Holographic projection defines more places

Holographic projection applications are one of the most popular projection methods available today. "Hatsune Miku" is the world's first virtual idol to use holographic projection technology to hold concerts. Although the technology at that time was not mature enough, the stunning effect of the holographic projection prototype has already impacted many people's nerves. Other industries have also borrowed holographic projections. In the catering field, the holographic restaurant serves as the next outlet for the restaurant, satisfying both the taste of the diners and the vision of the diners. The rapid development of the consumer industry has prompted the public to pay more attention to the experience. In the choice of restaurants, not only is it good to eat, but also has an atmosphere. Users want to have a sense of ritual for every meal. In the field of exhibitions, holographic projections have become the “dancing” of digital exhibition halls, especially in exhibition halls,such as science and technology museums, corporate exhibition halls and museums. This kind of projection display technology does not need to be carried by physical objects, and can realize stereoscopic images "out of thin air" in real space. The display form has the advantages of flexible projection, high definition, cost saving and novel form. The current tourism industry, not only attractions can attract passengers, but also need to add new elements, so that attractions attract attention, "eye- catching" is more "golden"! Adding holographic projections to the scenic area can easily bring exciting and interesting interactive experiences in any public area, mobilizing the enthusiasm of the audience and helping to gather popularity. Holographic projection technology can enhance the value of the product, and let the audience leave a deep brand impression in the process of shocking the technology display. DHN will bring more surprises to everyone!

DHN Laser projectors promote the transformation of traditional teaching mo

As multimedia technology enters the school, multimedia tools such as computers and projectors are increasingly becoming indispensable equipment in classroom teaching. However, the lack of operation and function of these devices is also increasingly obvious, mainly in the following: content display is dull, can not mobilize the enthusiasm of teachers and the enthusiasm of students to learn; lack of interaction and communication between teachers and students, can not receive the ideal Teaching effect. As a result, many schools have begun to replace teaching equipment, and the application of interactive large-screen projection has brought new inspiration to the transformation of traditional classrooms. For some problems in the traditional classroom, let's take a look at how the DHN laser projector DM907 is playing its functional role in the education field. Question 1: After writing on the whiteboard, it is easy to leave a mark, which is not clean and affects the next use effect. Solution: DM907 uses touch as a human-computer interaction method. The hardware uses a high-precision recognition infrared camera. The infrared pen can smoothly and accurately perform writing, drawing and touch operations on the curtain wall. It can replace the current interactive mode of electronic whiteboard + projection on the market, providing a more convenient solution for education and teaching. Question 2: In order to ensure the clarity of the projected picture, the traditional classroom needs to close the doors and windows, pull the curtains, and turn off the front lights, but the darkness in the room is not conducive to writing and reading. Solution: DM907 adopts the latest laser light source, in addition to color, it can synthesize the color gamut coverage of more than 90% of the natural color seen by the human eye, achieving perfect color reproduction, at the same time, brightness up to 4500 lumens, higher brightness and comparison The long service life greatly reduces the maintenance cost in the later period. The color gamut is wide, the brightness is high, and the service life is long. It can be seen clearly without pulling the curtains off the lights, and does not affect the students' copying notes. Question 3: The traditional projector is easy to be blocked by the human body, and the light is easy to glare on the face and the LCD screen is easy to use. Solution: DM907 is an ultra-short-focus laser display projector, which is installed on the wall. It can project a 100-inch large screen at a distance of 0.5 meters from the blackboard. People are usually in the area outside the projector and the screen. The area will not have projected light to the eyes, and the DM907 will be designed with more care and health. Teachers and students can use it with peace of mind.

DHN Laser Projector Application Immersive Project Hotel

The emergence of hotels has a history of nearly 600 years since the embryonic Hotel appeared around 1400 A.D. in Britain. Although China was also the first country in the world to emerge hotels, the Beijing Hotel built in 1900 and the Chinese Hotel built on the Bund of Shanghai were the real representatives of the emergence of Chinese hotels. Since then, the hotel industry has begun to flourish. Especially since China's reform and opening up, the rapid development of the market economy and tourism economy has brought unprecedented opportunities to China's Hotel industry. But at present, most hotels in China have the same design, lacking characteristics and creativity. Many star-rated hotels in major cities in China are strikingly similar in Hotel planning, architectural design, functional layout, interior style, materials, and techniques, resulting in exhaustion and inadequate competition, and causing a lot of losses to the state and investors. In fact, every hotel should have a completely different temperament and characteristics because of the different city, region, adjacent buildings, local human and ecological environment, different hotel management, different market positioning. However, it is a common phenomenon in many hotels in China that interior design only emphasizes wall design and ignores the overall atmosphere. Hotel is a special building enclosed space, not only to meet the people's accommodation, catering requirements but also to meet the meeting, business, entertainment, fitness, and many other needs. It is not only a functional application but also a spiritual sublimation so that customers can experience cultural infection and artistic edification while staying in hotels. Most mid-level hotels in China are full of high-grade materials, and the decoration interface is extremely luxurious. But the overall atmosphere is not very ideal, and even makes people feel bauble. At the same time, with the development of the information industry, we can find pictures, videos and comments of related hotels anytime and anywhere, which makes the hotel industry more and more demanding for decoration and services. At the same time, with the rise of major social platforms, operators urgently need to publicize their hotspots on public social platforms such as Tik Tok, Wechat and Weibo, which once made many hotels. Industry-related personnel wants to break their heads and even lost their way in Hotel operation. In the past two years, "holographic hotel" and "Immersive project hotel" rely on laser projector technology, with a new style began to enter people's horizons, showing their prominence in the hotel industry. When a brand new thing begins to develop, people must have many doubts: Is the projector reliable now? With the development of science and technology, the former bulb projector has gradually declined, and laser projection has gradually occupied the market by virtue of its own technological advantages. In the past, the life of projectors was short, averaging 2000 to 3000 hours, and good projectors were only 4000 to 5000 hours. Because of the inevitable heat dissipation problem of the bulb machine, it could only be used for about 4 hours continuously. The Laser Projector of DHN had a life span of 20,000 hours, and it had no problem using 24*7 hours continuously. In addition, DHN's Lesser Projector uses a fully sealed dust-proof design and a liquid heat dissipation system to ensure that the projector will not cause too much loss to the life length of the machine itself under all-weather working conditions. Is the cost of such decoration very high? Traditional hotel decoration investment in human, material and financial resources is very large, in order to make the hotel unique, often need to invest more cost in design, but may not be able to achieve the desired results. The construction of a holographic hotel can be accomplished with only a few projectors, a fuse, and a computer. The wall does not need gorgeous decoration, and the white screen can be done well. Moreover, as long as a specific film source is made, different themes can be changed at any time and different styles of these hotels can be created, which is equivalent to having many different hotels at the same time. Why choose the Laser Projector of DHN? 1. Brand Integration DHN Laser Display Projector provides a complete set of technical solutions, with fusion and advertising system, which integrates control, integration, content, and publishing. The brand has a higher degree of professionalism. By using the advertisement publishing system in the hotel, a hotel information wall can be built on the prominent wall. The real-time information and various dynamic information in the hotel can be released in time for customers and staff to read. To a certain extent, it meets the needs of public announcement information. In addition, through WAN, the centralized management of multi-city terminal equipment and the unified release of programs can be carried out remotely, which can support the timing switch of equipment and truly achieve unmanned management. 2. Product differentiation The product itself has a built-in fusion function and 17*17 grid correction function. Short-focus and ultra-short-focus lenses have a projection ratio as low as 0.25:1. A single projector installed at a distance of about 1 meter can project a large picture of 4 meters wide. Many unique advantages can ensure that customers want to create a variety of different effects. Make the difference between hotel and hotel more obvious, which is more conducive to the formation of their own brand unique style. 3. Brand Authority DHN's aser project has passed a series of international certifications such as FCC, CE, CB and a series of domestic certifications such as 3C, ISO 9001 (Quality Assurance System) and ISO 14001 (Environmental Management System Certification). At the same time, it has also obtained a large number of relevant certificates in professional technology. 4. A large project design team DHN's Lesser Projector has a professional project design team behind it. Years of on-site experience can enable them to provide corresponding project solutions to different needs of customers. Therefore, DHN's Lesser Projector not only has a large number of excellent cases in the catering and hotel industries but also in the exhibition, new media, new applications, education, government, and enterprise fields and has been widely recognized. The development and management of modern hotels need convenience and efficiency. In order to highlight the characteristics of hotel management, we need to keep pace with the times. Under the background of the hotel industry with serious homogeneity nowadays, if we make timely use of high-tech transformation, we can play a very good positive role in meeting the personalized needs of customers.

DHN Laser Projector The Introduction of 3D Projection Technology

3D projection technology relies on 3D technique, the following passage is the principle of 3D technique, let's look at how do 3D projectors work. Barrier 3D technique is also called parallax barrier or parallax barrier technology, its working principle is similar to polarimetric 3D's, it is researched for decades by engineers of Xiapu European laboratory. Barrier 3D technique is compatible with LCD technology, so it has advantages on productivity and cost, however, its image resolution and lightness will be reduced. The implement method of barrier 3D technique is using a switching LCD, polarization film and polymer liquid crystal layer to produce a series of vertical stripes with 90°. These stripes are dozens of micron, vertical stripes are formed through their light, it is called parallax barrier. This technology is using the parallax barrier that is put on the back light unit and LCD panel, in stereoscopic mode, an image that should be seen by the left eye appears on the LCD screen, with opaque stripes blocking the right eye, in a similar way, when the image that should be seen by the right eye is displayed on the LCD screen, the opaque stripes will block the left eye. By separating the visual images of the left eye and the right eye, the viewer can see the 3D image, which is full of dreams. Advantages: It has advantages on productivity and cost, which is suitable for civilian consumption. Disadvantages: At low brightness, the resolution decreases inversely with the increase of the image broadcast at the same time. Lenticular lens technology is also called biconvex lens or microcylindrical lens 3D technology. Its biggest advantage is its lightness won't be influenced. The principle of lenticular lens technology: the image plane of the LCD screen is located on the focal plane of the lens. In this way, the pixels of the image below each column lens are divided into several sub-pixels, so that the lens can project each sub-pixel in different directions. Therefore, eyes can see different sub-pixel from different angles.However, the gap between pixels will also be magnified, you can't simply superimpose sub-pixels so that the column lens is not parallel to the pixel column, but at a certain angle so that each set of sub-pixels can project the viewport repeatedly, instead of just projecting a set of parallax images. The reason why its brightness will not be affected is that the columnar lens will not block the backlight, so the picture brightness can be well guaranteed,However, the basic principle of 3D display is similar to parallax barrier technology, so the resolution is still a difficult problem. Advantages: its lightness won't be influenced with better effects of display. Disadvantages: related manufacturing is not compatible with existing LCD processes and requires investment in new equipment and production lines.

DHN Laser Projector How to Overlay Projection of Two Projectors

Laser projector suppliers Shanghai DIDON Industrial Co., Ltd. wholeheartedly provides customers with high-quality projection solutions. Usually, according to the situation of the project site, if the distance is long, the environment in the room is brighter, and the brightness of using a DIDON machine is certainly not enough, so two DIDON projectors are needed to superimpose. Superposition is widely used, and lumen superposition of projector is an important aspect. The advantages of projection superposition and the equipment used: 1.Ultra-high brightness and ultra-low-cost Superposition system is suitable for users with brightness requirement of 7000 A NSI lumen or more. But the price of 5000 ANSI lumen or more is extremely expensive. In order to save cost, many users have to sacrifice brightness, and then choose a projector with lower brightness and lower price to replace it. The use of the two-machine superposition scheme, you can exchange for a very small investment in high-performance and high brightness effect, the performance-price ratio will be increased by 3-10 times. 2.Control software The application of projector overlay includes two ways: standing and hoisting. Users can simply click through the mouse to set the start, shutdown and use mode of any projector, and the software interface. 3. Choosing rotation mode can boot for a long time Users can control the boot mode to turn the projector on in turn and can set the single boot time. The system provides default time and optional time range. After choosing this mode, the projector will switch on and off alternately. In this way, for users, it solves the problem that ordinary projectors cannot start for a long time. Powerful superposition function projection fusion technology is a major innovation. Simple superposition can be achieved without any software assistance, generating double lumen brightness. Digital courtyard line into the mainstream market 4K can live in the family as expected. At present, projector superposition is not only used in conference rooms, theatres, museums, auditoriums, public places, schools, research laboratories and other application fields, but also in the main control system of traffic or power detection, as well as the command center of public security, fire control, aviation control, space development center and other units. As an economical solution, the high-brightness overlay of projectors brings users not only a larger picture and higher brightness but also effective control of the purchase cost. All these indicate that the lumen Superposition Technology of the projector is becoming mainstream. Laser Projector Suppliers Shanghai DIDON Industrial Co., Ltd. provides system integration, information solutions and IT services for Industry and enterprise customers. Not only has an excellent distribution management team, long-term cooperation with customers and manufacturers to create common growth and common profits, but also devotes to expanding diversified products and markets, has excellent technical team, has a strong accumulation of program design and integration capabilities.

Projector Resolution and Contrast Selection

Resolution: the projection resolution can be selected according to the actual projection content for deciding what grade of projector to buy. If the demonstration content is dominated by general teaching and word processing, you can select SVGA(800 600); if the demonstration of fine images (such as graphic design), you can choose XGA(1024 768). Since the mainstream resolution of laptop and desktop is to meet the XGA(1024 768) standard, it is recommended to choose the projector with the XGA(1024 768) resolution if the budget allows. No matter what kind of digital products, the resolution is everyone's concern factor. Common resolutions and representations are as follows: SVGA: common resolution for 800x600 budget projector XGA: 1024x768 projector resolution for mainstream business and education projectors 720p: 1280x720 or 1280x768 mid-range resolution for home projectors 1080p: 1920x1080 or 1920x1200 resolution for high-end home projectors At present, the price of 4K is more expensive than market price. Therefore, the general 800*600-1080p resolution of the projector in the office and home use can according to the personal requirements and pursuit Contrast is a concept that everyone is very familiar with. In daily photo editing, it is estimated that contrast determines how many color levels an image can recognize, and it is the key to see more details. In addition, the contrast has a great impact on the imaging of the projector. Usually, after the resolution reaches 1080p, the contrast has a greater impact than the increase of the resolution. Most LCD projectors have a nominal contrast of about 400:1(ANSI), while most DLP projectors have a nominal contrast of more than 1500:1(all white/all black). The higher the contrast, the higher the price of the projector, if only using the projector to demonstrate text and black and white pictures, projectors whose contrast is about 400:1 projector can meet the needs, if it used to demonstrate colorful photos and play video animation, the best choice is 1000:1 high contrast projector.

What is Edge Blending Technology

Edge blending technology is to overlap the edges of the images projected by a group of projectors, and show a brighter, larger and higher resolution whole picture without gaps through fusion technology. The effect of the picture is just like the picture quality projected by a projector. When two or more projectors project a picture on both sides, some of the image lights will overlap. The main function of edge fusion is to gradually lower the light brightness of the overlapping part of two projectors, so that the brightness of the whole picture is consistent. Edge blending projection technology has experienced three stages of development: hard edge stitching, overlapping patchwork and edge blending technology. Hard edge stitching(simple stitching): it refers to the edges of the two projectors are aligned without overlap. The display effect shows that the whole picture is divided by a seam. If the projector edge is not enhanced with brightness, the seam is shown as black. If the edges of the projector are enhanced, the seam appears white. Simple stitching: that is to say, the pictures of the two projectors are partly overlapped, but there is no light in and out, so the brightness of the overlapped part is twice of the rest of the whole picture. In terms of the display effect, the overlapped part is a bright strip. Edge blending technology: compared with the simple overlapping method, the brightness of the right overlapping part of the left projector decreases linearly, and the brightness of the left overlapping part of the right projector increases linearly, which shows that the brightness of the whole picture is completely consistent in the display effect.

What are the Special Parts of Short Throw Laser Projector and Ultra Short T

We all may experience such situations: When you stand on stage to preside over a meeting or give a speech, a projected light may hit you in the face and irritate your eyes; or the part of light onto you, so the image is blocked and can not be presented to the audience. It affects the visual experience of the audience. The main reason is that the projectors installed in most meeting rooms and classrooms are equipped with telephoto lenses. Due to the limitations of the telephoto lens, it gradually fails to meet the needs of users in various scenes and venues. At the same time, with the development of projection technology, short - and ultra-short - focus lenses begin to market. Short throw laser projector and ultra short throw projector are far beyond the confines of space. Compared with the long or medium throw laser projector, it can give full play to its advantages. Therefore, they have developed rapidly in various market fields, especially in the field of education. So, what are the characteristics of a short throw laser projector and ultra short throw projector? Why are they preferred by users? Let's take a look. High flexibility, suitable for small space DHN has two-star products, DM350X with a 0.6 short focus lens, DM907 with a 0.25 ultra short focus lens. Projectors can be installed closer to the picture, so panoramic applications can be performed in a smaller indoor space, providing more flexibility in installation. Project big pictures in small space Since the projection ratio of the two projectors is lower than 0.25 and 0.6 respectively, it only needs 0.55 meters and 1.2 meters to project a 100-inch picture, which can also project a big picture in a narrow space. Give users more space to move around Since the projection ratio is very low, the projected light occupies a very small space distance. Users can move in areas beyond the projected light without being stimulated by the light to their eyes. Picture integrity will not be damaged for being blocked by people. There is also more room for users or speakers. In addition, short throw laser projector and ultra short throw projector are also the first choices for interactive handwriting, with a rear projection. It is these advantages, short throw laser projector and ultra short throw projector are preferred by users. Its sales are also on a year-on-year growth trend. Especially in the field of education, it overcomes the problem that the strong light from the projector can directly shoot into the speaker's eyes, bringing direct stimulation and affecting the vision health. They achieve the best sharing of a clear large picture in the smallest space. Short throw laser projector can also reduce the projection distance of the projector. More importantly, it can effectively increase the interactivity of teaching. In addition to the education field, the application field of a short throw laser projector and ultra short throw projector is wider. It is believed that in the near future, short throw laser projector and ultra short throw projector will occupy all fields with the advantages. We will come to the age of short throw laser projector and ultra short throw projector.
