Technology advances to promote LED full-color display indoor applications

On November 4th, the Beijing International Exhibition Center opened the seventeenth Beijing International Radio, film and television equipment exhibition (BIRTV 2008), LED large screen display. Several venues inside and outside, more than and 10 color LED display screen has become the most color of the exhibition products.

Radio and television show, including MITSUBISHI, akami, Zhaotong, Hongyuan, Richland, Hibino and many other brand manufacturers or dealers shows the number can be used for indoor studio hall, lecture hall, venue or lobby areas such as full color LED electronic display screen products. Indoor LED screen to become the most important display of radio and television show LED types. The collective emergence of various manufacturers, indicating that the LED indoor application market has entered a mature stage.

Previously, outdoor LED screen and data display type LED screen applications has been the main market for LED display". A participant of the manufacturers to the author, but now the indoor full-color video applications are gradually becoming another mainstream market LED big screen". According to reports, LED large screen display reduced greatly enhance the resolution due to the pixel size. This makes the interior of the screen with the best viewing distance becomes smaller, the picture is also significantly enhanced the degree of fineness. Our screen is the biggest characteristic of the distance is only 3 mm, akami LED screen vendors of this introduction, "in the picture on the screen is delicate, hitherto unknown...... At the same time, it also reached 1700 lumens brightness, the lowest brightness can also be adjusted to 1200 lumens". To see this product with red pixel size for small introduced products manufacturers and many. In addition to the red saw 3 mm products, MITSUBISHI also exhibited a only 3*3 mm LED mm spacing screen.

Narrowing the pixel spacing must ensure that the mechanical strength and brightness of the product, a professional and technical personnel to the author, the previous pixel spacing smaller product brightness is always not up to the requirements". See the red LED screen vendors also indicates the importance of brightness of the LED display screen, the screen (point spacing of 3 mm LED screen brightness) and most of the LCD or plasma display products compared to the much higher, so a large studio is more suitable for LED display products, 3 mm spacing screen "best watch at the distance of 5 meters outside the" fully meet the needs of the ultra clear picture appreciation.

In addition to the products from the index on the radio show, MITSUBISHI also emphasized the stability and application of the product. A product of MITSUBISHI LED terminal display all hidden in the box body, and a maximum of six layers of stacked assembly does not need special support stable LED wall can rely on its mechanical strength support the weight of the screen box. According to reports, MITSUBISHI's LED products are fully used in Japan's original products, including a screw are original products in japan". At the same time, MITSUBISHI also guide lists MITSUBISHI heavy industries, the fact that the world's most important ship manufacturer, to illustrate the usability, stability and comprehensive quality of the importance of product in MITSUBISHI corporate culture.

Radio and television show another very interesting LED products from Japan's Hibino brand. Hibino exhibited a thin structure of LED splicing products. This product adopts the rope hoisting mode display, display and screen wall type LED floor type ordinary completely different. Hibino LED screen really attractive place is excellent performance. Whether it is pixel fineness, color or grayscale images have their unique performance, especially the scene of the sense of hierarchy, three-dimensional sense can bring people almost immersive perception.

Hibino LED screen performance and special way of lifting, show a broader space for indoor applications LED screen to the audience: bar lifting, film and television program production application stage application, high quality field is the screen play the charm of the place.

LED outdoor applications are mainly brightness upgrade, the exhibition exhibitors Beijing Regent photoelectric manufacturers on behalf of the author, the indoor application of the LED products are highly integrated performance requirements". The company exhibited a variety of indoor and outdoor products in the radio and television show, one indoor whole package "LED TV", and adopts the tricolor single integration, interior waterproof design of outdoor LED products is very characteristic, but also one of the company's exclusive products.

The Regent's comments represent a general view of the LED manufacturers' indoor applications for LED products. Indoor applications tend to be closer to the audience and the product, so that the product will be exposed to any display defects. Interior applications on the LED point spacing, color uniformity, gray scale effect, the installation process, such as the requirements of the screen flatness is higher, a participant in the profession pointed out

The radio show, can be regarded as an overview of recent development of the indoor LED display technology. Many manufacturers, all kinds of technology products into battle, indicating that the technical bottleneck of LED large screen indoor applications has been a breakthrough, LED display industry is about to usher in the golden period of explosive growth in the indoor market.
