Recently, many customers asked why the LED display must use the
video processor this problem, it is not an exaggeration to say that the merits of the video processor directly determines the full-color LED display a display effect. Today LED Controller Store to bring the majority of users to understand this issue in depth:
1, motion compensation
On the slow image and fast image motion compensation. Good motion compensation technology can be very good to reduce the full color LED display motion image edge jagged phenomenon.
2, de-interlacing
Video signal for better reduce bandwidth, so improve the resolution must also use interlacing technology. Full color screen this time the need for interlaced signal preprocessing signal. Good to deal with the interlacing technology and eliminate the live broadcast and filming of the tracing effect.
3, scaling
LED screen is usually a modular design and splicing display, because it is the most flexible of all flat panel display media in a display product. But this product also has some disadvantages, that is, the flexibility will be slightly slowed down, especially each engineering application of the display resolution in the standard are difficult to find. So especially need video processors to provide scaling capabilities.
4, image reduction
General display project applications in the dot matrix resolution of 1024 * 768) below. Need to have access to the video processor will be accessed by the various signals reduced to the corresponding terminal resolution, the video processing equipment is required to have a point-by-point pixel scaling function.
5, image enlargement
As more and more engineering applications such as the amount of advertising and other business surges, full-color
LED display resolution is no longer limited to the conventional resolution, some engineering applications and even reached the level of 2048 points in similar applications, the need for video processors can have image amplification processing technology, and video processor internal processing bandwidth can be reached or exceeded atypical applications. The dot matrix area.
6, noise suppression
Due to the full-color LED display dot matrix characteristics, in other flat panel display medium in the insignificant noise, will greatly challenge the LED display audience's psychological tolerance. Noise mainly from the video signal compression noise and the system itself random noise, excellent
video processor can be noise suppression, minimize the noise on the picture quality of the interference itself.
8. High service life
DIDLCD LCD backlighting service life of up to 5-10 million hours or more. This ensures that the splicing display using each piece of
LCD screen after a long period of time, the brightness, contrast and color consistency and to ensure that the service life of the display is not less than 50,000 hours.
9. Reliability is better
Ordinary LCD screen for TV, PC monitor design does not support continuous use day and night. DID LCD screen for monitoring center, display center design support in 7x24 hours continuous use.
