“Today, radio and television customers are more and more fond of using LED screens. Many new studios will explicitly request DLP and LED solutions in the bidding of large-screen equipment, which was unthinkable a few years ago.†Guangdong Weichuang Video Technology Chen Liang, sales manager of the company limited by shares (hereinafter referred to as “Weichuangâ€) said.
Therefore, following the successful display of 2.48mm small-pitch LEDs on BIRTV last year, Wistron once again launched this year, using a smaller pitch of 1.92mm products to jointly build an LED full-media studio system with the Chinese Ocean Ocean, and simulated the sports feast ( The World Cup), international current affairs (US Pacific Rim), weather reports and emergency reports have attracted many professional visitors to watch and consult, so that Chen Liang is busy.
Demanding is strict . Although the broadcasting and television industry is not as complicated as the command dispatching and control room requirements for the diversity of display signals, it is the most demanding for the quality and stability of large-screen displays. It is understood that for color temperature Accuracy, color reproduction The radio and television industry has strict standards, and safe and stable operation is the most important, especially the focus of the studio. Because of the stable operation and fine resolution, DLP splicing walls can dominate the broadcasting studio for decades. After 2011, small-pitch LEDs (with a dot pitch of 2.5 mm or less) gradually entered the public eye and began to be accepted by the studio.
In the past two years, LEDs have been leaps and bounds. With the improvement of LED display manufacturing technology, the resolution of small-pitch LED screens has been continuously improved, and the refresh rate, contrast, grayscale, and noise have been greatly improved. The LED screen has the advantages of complete visual seamlessness, wide color gamut, adjustable brightness, large visual range, slim screen and low maintenance cost, so it is increasingly favored by customers in the broadcasting industry.
Technological breakthroughs <br> <br> face of radio and television industries for applications with small spacing LED products, Chong Wei has increased the LED technology R & D investment, made a series of technological breakthroughs. For example, based on its rich accumulation of signal processing and display in the control room for many years, it has broken through the real-time synchronization problem between LED screen signal processing and realized powerful high-resolution multi-screen signal processing capability.
Secondly, the use of single-point brightness and chromaticity correction technology solves the problem of display color inconsistency caused by inconsistent LEDs, supports skin color reduction technology, makes the screen display content closer to the real picture, effectively eliminates the mosaic phenomenon, and makes the screen brightness. The color is highly consistent and the image becomes softer and more delicate.
Third, support refresh rate customization, with the current industry's highest refresh rate of 6800Hz, under the normal viewfinder and rotation of the camera, the LED screen display is stable and flicker-free, and the gray level is excessively smooth at the highest refresh rate, there is no cross color.
Fourth, the moiré is effectively eliminated. In the application scenes such as the live broadcast of the news and the recording scene of the variety show, the LED large-screen display wall is often used as the back view. When shooting with the camera, the LED screen will inevitably be captured, and the viewer watching the program often sees similar images. The texture of the water wave appears, and with the change of the shooting angle and the adjustment of the focal length of the camera lens, some changes will occur in the water ripple, which greatly affects the display effect of live broadcast and recording. This water ripple is called moiré.
Through the use of the optical screen, Wistron changed the display state of the LED screen from the original grid-like display to a continuous surface display. By displaying the discrete LED pixels, a continuous pixel display is formed on the surface of the optical screen. It improves the contrast while retaining high definition and eliminating moiré.
Fifth, the first system power supply integrated design, the power supply distributed in each display unit box is integrated and integrated, and the power supply hot swap design is supported to realize the power redundancy of the N+m system. When an abnormal power failure occurs in a certain power supply, other power supplies automatically perform automatic current sharing, which does not affect the normal use of the system, and effectively improves the system's trouble-free running time and reduces the fault maintenance time. At the same time, the high-heating power source is removed inside each display unit, and the pure die-cast aluminum is naturally dissipated, no fan is needed, and has ultra-quiet characteristics, which is more suitable for studio applications.
Since Weichuang DLP splicing wall has established a good reputation in the broadcasting industry, its small-pitch LED application program for the broadcasting industry has been widely concerned, and has been widely adopted by Phoenix TV, Beijing TV and other broadcasting companies. Today, Weichuang has a variety of LED products with a pitch of 2.48mm, 1.92mm, 1.86mm, 1.48mm, etc., for users with different needs.
<br> <br> comprehensive development of small pitch in Granville made a series of breakthroughs on the LED at the same time, Chong Wei did not relax DLP and LCD development. For some studios to meet the needs of large screen high brightness, Weichuang DLP display system has specially designed a high-brightness LED projection movement, which makes the studio lighting settings more flexible and enhances the performance. In addition, WeChuang also developed a 16:9 DLP splicing unit for HDTV display requirements, and adopted an anti-reflective screen, which is suitable for scenes with strong lighting in the studio environment. At the same time, it is widely used for broadcasting and television to adopt HD-SDI signals. Both the DLP display unit and the processor are equipped with an HD-SDI interface that supports high-score input and will support 4K input in the future.
In terms of LCD, Wistron aimed at the monitoring and broadcasting application of radio and television. The outstanding features of Weichuang LCD splicing system are equipped with core processing chips and boards with independent research and development and full intellectual property. No need for external matrix and processor, the splicing wall system can also realize various typical splicing display applications. A variety of signals in the room and monitoring room are directly on the screen, enabling roaming, superimposition, and multi-screen display.
At present, Weichuang large-screen splicing system has been successfully applied to CCTV news studios, Beijing TV stations, Qinghai TV stations and other broadcast and television industry customers, and its excellent adaptability and flexibility make all types of programs become more vivid.
“Weichuang does not rely on a certain display technology, but provides solutions based on the actual needs of customers, creating value for customers.†Chen Liang said. In fact, as early as 3 years ago, Weichuang determined the strategy of comprehensive development, combined with the technological development trend of the display and control market, DLP, LCD, LED three arrows, using the advantages of each product line, complement each other, to solve the solution The form of the user's complex information is presented in a flexible, centralized and intelligent way to help customers achieve diversified applications. This is the core competitiveness of Wistron. (This article is published by Wei Chuang)
