AI Technical Summary

Technical Problem

In existing technologies, Demura technology, which uses a fixed-area detection method, results in a huge amount of data in flash memory, increased costs, and a lack of flexibility.

Method used

By dividing the display panel into multiple pixel blocks, determining detection points and comparing data, recording the position and compensation data of abnormal pixel rows, and storing only the start and end positions and compensation data of abnormal pixel rows in the flash memory.

Benefits of technology

This significantly reduced the amount of stored data, improved flash memory utilization, lowered device costs, and enhanced product competitiveness.
