AI Technical Summary

Technical Problem

The LED beads on the existing backlight board emit light uniformly, resulting in the same brightness in different areas. This makes it difficult to improve the display contrast, affects visual perception and display clarity, and the brightness does not adapt to changes in the environment during the day and at night.

Method used

Multiple light-emitting areas are set on the backlight panel, and the brightness of each light-emitting area is controlled by a circuit board to achieve brightness adjustment of different areas and adapt to the brightness requirements of different environments.

Benefits of technology

It improves the contrast ratio of different areas of the display screen, enhances the visual experience, ensures good brightness adaptability of the display screen in different environments, and improves the clarity of the displayed content.
