AI Technical Summary

Technical Problem

Existing LED display panels face challenges in maintaining uniform brightness across replaced LED modules, leading to non-uniform brightness characteristics and increased power consumption due to unnecessary standby power in display operations.

Method used

The LED display panel employs Gray Scale Pixel (GSP) control to calculate grayscale values for each display section, using a pre-stored table to generate control signals for blinking frequencies, and integrates RGB pixel control to minimize power consumption by cutting off standby power during brightness correction.

Benefits of technology

This approach ensures uniform brightness and clear images while reducing power usage by minimizing current consumption and shortening brightness correction times, stabilizing display operations, and enhancing image quality.

Abstract

The present invention relates to a power-saving LED electronic display board having a remote correction function through gray scale pixel (GSP) control, in which individual RGB pixel control of a pixel current value, changed to a pixel correction value by pixel power control, is enabled through power pixel control of an LED module drive circuit, so that display is rendered on an electronic display board by a stable circuit configuration not only during display driving but also during display driving of the electronic display board after luminance correction, thereby minimizing current consumption of the electronic display board.
