AI Technical Summary

Technical Problem

The display device has insufficient visual effect when displaying light spots or small bright objects, and the visual accuracy of the boundaries of large bright objects is insufficient, resulting in uneven brightness.

Method used

A brightness calculation module is used to calculate the brightness difference value, and a brightness enhancement module adjusts the driving current of the backlight module based on the average difference value and the original brightness value to improve the brightness of the display area.

Benefits of technology

It increases the brightness of small bright spots or objects on the display screen and improves the visual uniformity of large bright objects, thus improving the problem of uneven brightness and providing a good visual brightness effect.
