AI Technical Summary

Technical Problem

Existing always-on display technology cannot flexibly adapt to changing application scenarios in terms of refresh rate adjustment, resulting in inaccurate power consumption control, and the backlight zoning technology has uneven brightness issues.

Method used

The refresh rate is adjusted in each independent always-on display area according to the static and dynamic conditions of the image content. Combined with backlight zoning technology, white balance is consistent by adjusting the backlight intensity and the grayscale relationship of the original image, and the duty cycle of the backlight is adjusted to reduce power consumption.

Benefits of technology

It achieves adaptive adjustment of screen refresh rate based on the degree of motion difference in image content, reduces power consumption, and maintains consistent white balance and brightness in multi-region display, adapting to diverse application scenarios.

Abstract

本发明公开了一种熄屏显示中刷新率的调节方法和计算机可读存储介质。该方法包括:根据该区域的当前帧灰度图像中任意像素P(x,y)与下一帧灰度图像中任意像素P’(x,y),计算前后两帧图像,得到残差图像里的任意像素△P(x,y);根据残差图像里的任意像素△P(x,y)计算在M行*N列像素里属于相对运动的像素个数Pd,以及属于相对静止的像素个数Ps;根据相对运动的像素个数Pd,相对静止的像素个数Ps,以及提前根据不同的应用场景设置的刷新率阈值组,确定该区域当前所需的刷新率Refresh。采用本发明的方法能使每个独立的熄屏显示区域根据图像内容的静态和动态情况调整各自区域的刷新率从而降低功耗。
