AI Technical Summary

Technical Problem

On the premise of ensuring visual effects, how to reduce the system power consumption of high refresh rate display screens to improve the system usage time and ensure the service life of the battery, especially in low frame rate application scenarios.

Method used

By determining the target frame rate of the current application scenario and adjusting the screen refresh rate of the display panel in real time according to the target frame rate, it matches the target frame rate of the current application scenario.

Benefits of technology

It realizes that the system power consumption of the high refresh rate display is reduced without affecting the visual effect, extending the system's service time and extending the battery life.

Abstract

The present invention provides a driving method and system for a display, the driving method comprising the following steps: determining a target frame rate of content in a current application scene; adjusting a screen refresh rate of a display panel in real time according to the target frame rate of the content in the current application scene, so that the screen refresh rate of the display panel matches the target frame rate of the content in the current application scene in real time. The present invention determines the target frame rate of the content in the current application scene, and then adjusts the screen refresh rate of the display panel in real time according to the target frame rate of the content in the current application scene, so that the screen refresh rate of the display panel matches the target frame rate of the content in the current application scene in real time, so that the display panel can quickly adapt to the current application scene, and adjusts the screen refresh rate to the best matching state with the current content frame rate, so that power consumption and performance are well balanced, and the problem of how to reduce the system power consumption of a high-refresh display screen to increase the system usage time and ensure the battery life while ensuring visual effects is solved.
