AI Technical Summary
⚠Technical Problem
Existing technologies for reducing driver IC temperature suffer from high costs, performance impact, and an inability to effectively reduce the temperature of non-display areas.
⚗Method used
The LCD panel driving circuit system adopts a variable drive level. The timing control module generates the control timing and adjusts the drive level of the LCD panel during non-display periods to be lower than the drive level during normal display periods, thereby reducing the power consumption of the data driving module.
🎯Benefits of technology
It effectively reduces the temperature of the data driver module and IC, improves working efficiency and stability, avoids overheating damage, and reduces production costs.

Abstract
The application provides a liquid crystal panel driving circuit system for reducing IC temperature, which comprises a timing control module, a data driving module, and the timing control module is used for generating control timing and image display required data by receiving front-end data signals; the data driving module is used for opening corresponding control end according to the control timing; and the data driving module is used for driving the liquid crystal panel to display data by using the brightness of each pixel point in the image display required data and a driving signal, and adjusting the driving gear of the liquid crystal panel to be lower than the driving gear in the normal display period in the stable output stage of adjacent lines or / and the non-display period of adjacent frames switching. The application reduces the driving capacity of the data driving module in the non-stable output stage or / and the non-display period by using the variable driving gear, so that the data driving module works in a low-power mode, the temperature of the data driving module is reduced, and the working temperature of the IC is reduced.
