The effect of video processor on full color LED display

Recently, many customers have asked why the full-color LED display has to use the video processor. It is no exaggeration to say that the quality of the video processor directly determines the display effect of the full-color LED display.

Today, the company will bring a large number of users to understand this issue:

1. Motion compensation
Motion compensation for slow images and fast images. Good motion compensation technology can well reduce the edge aliasing of moving images during full-color LED display.

2, deinterlacing
Video signals are better for reducing bandwidth, so increasing the resolution requires interlaced scanning. Full color screens require pre-processed signals for interlaced signals. It is good to handle interlaced scanning technology and eliminate the effect of line drawing during live broadcast and shooting.

3, zoom
Full color screens are typically modular and spliced, as they are the most flexible display of all flat panel display media. However, this product has some drawbacks, that is, the flexibility will be slightly slower, especially the display resolution of each engineering application is difficult to find in the standard. Therefore, the video processor is especially required to provide a zoom function.

4, the image is reduced
In general, the dot matrix resolution of display engineering applications is below 1024*768). The video processor is required to reduce the respective signals accessed to the resolution of the corresponding terminal, and the video processing device is required to have a pixel-by-point pixel scaling function.

5, image enlargement
Due to the rapid development of more and more engineering application advertising volume, the resolution of full-color LED display is no longer limited to the conventional resolution, and some engineering applications even reach the level of 2048 points in these applications. The video processor needs to have image magnification processing technology, and the internal processing bandwidth of the video processor can reach or exceed the dot matrix area in atypical applications.

6, noise suppression
Due to the dot-matrix characteristics of full-color LED display, the insignificant noise in other flat panel display media will greatly challenge the LED to show the audience's psychological tolerance. The noise mainly comes from the compression noise of the video signal and the random noise of the system itself. The excellent video processor can suppress the interference of the image quality itself by noise suppression.

Here are a few of the commonly used LED display video processors:
1. Kayida KS600

★ HD multi-format signal input
★ Any signal fade in and out
★ 1920×1200 HD output
★ Two LED sending cards can be built in
★ Support PC software control
★ Offline scheduled tasks

Superb design
User-friendly panel design
The KS600 is equipped with a color display panel and two-way adjustment knobs. The friendly human-computer interaction interface greatly facilitates the user's use!
Multiple high definition signal inputs
The KS600 supports 5-channel high-definition clear signal processing, including: DVI × 1, VGA × 1, HDMI × 1, CVBS × 2. In addition, the KS600 can be built with two LED transmit cards and is designed with a pull-out design for easy installation. Free zoom display
Image scaling
The KS600 can zoom in or out at any time to complete the full-screen display of the source. In addition, the KS600 allows the LED display to play only partial images of the same resolution and can be quickly switched between full-screen and partial.
Fade effect switching
When the KS600 is switching signals
Supports the effects of fades and fades, eliminating black spots, blue screens and other undesirable phenomena. The coverage includes all signal switching between the external signal and the internal decoded signal.
Quick and easy operation

Navigation settings
The KS600 provides guided navigation settings, and users only need to make corresponding selections based on the prompts on the color screen to complete the device debugging, which is very simple.
Software and offline planning tasks
The KS600 can be connected to a computer via an RS232 serial port, which is perfectly compatible with KYSTAR control software. Through the software, the user can preset the device and command the machine to automatically complete the signal switching, brightness change and other instructions at a specified time.
