Advantages Of LED Display Video Processor

Why do full color LED displays screen require a video processor?

A good video processor is not only used to transmit signals, it also determines the quality of the final display effect of the LED display, otherwise the LED display will not be able to work normally and with high quality.

1. Solve signal source compatibility issues

Common video signal sources (such as computers, cameras, and Blu-ray players) typically output standard resolution signals (e.g., 1920×1080), and the signal formats (such as HDMI, DP, and DVI) are also designed for standard displays.

LED displays have irregular dot arrays, and their native resolution often doesn’t match the source resolution. A video processor acts like a high-level “translator,” accepting input signals of various formats and resolutions and translating them into specific control signals recognized by the LED display.

2. Improve image display quality, which is the core function of the video processor

(1) Noise reduction: Removes noise and aliasing from the video source to make the image cleaner.

(2) Sharpening enhancement: Enhances the edges and details of the image to make the image clearer and sharper.

(3) Color enhancement and correction: Improves the saturation and vividness of colors to make the image more vivid.

Performs color space conversion (such as YUV to RGB) to ensure accurate color reproduction.

Performs point-by-point correction on the LED display to compensate for slight differences in brightness and chromaticity between different lamp beads, eliminates “pitting” and color blocks, and ensures a uniform image.

(4) Contrast and brightness optimization: Dynamically adjusts the contrast and overall brightness of the image to make dark details clearer and bright areas less overexposed, adapting to different ambient light conditions.

3. Achieve resolution scaling and matching

Displaying a non-standard aspect ratio signal source (such as a 16:9 video) completely on an LED screen of any aspect ratio (maybe an extra-long screen, a vertical screen, a circular screen, etc.) will result in stretching or black edges. The video processor has a powerful image scaling engine. It can intelligently scale the image to adapt to the physical resolution of the LED screen and provide multiple display modes:

(1) Proportional scaling: maintains the original image ratio, but may have black edges.

(2) Full screen stretching: fills the entire screen, but may cause image distortion.

(3) Crop mode: crop the redundant part of the image to ensure that the key content is displayed.

(4) Picture-in-picture/multi-screen: display multiple signal source windows simultaneously on a large screen and arrange them freely.

4. Control and Management System

(1) Multifunctional Interface: Provides a wide range of input and output interfaces for easy connection to various signal sources and can control multiple LED cabinets or screen units.
(2) Frame Rate Synchronization: Perfectly synchronizes the output frame rate with the refresh rate of the LED display, fundamentally eliminating flickering and tearing of the image, ensuring stable and clear images even when shooting with high-speed cameras.
(3) High Grayscale Processing: Enables the LED display to display richer color levels and smoother color transitions, especially when displaying dark scenes, without losing details.

5. Achieve a variety of display effects

(1) Correction of special-shaped screens: For non-planar LED screens such as curved, spherical, and wavy shapes, the processor can perform geometric correction to ensure that the image fits the shape of the screen perfectly without deformation.

(2) 3D/LED virtual shooting: In film and television shooting and high-end events, the processor is the key to achieving high refresh rate, high grayscale, and low latency display, ensuring synchronization with the camera shutter.
