AI Technical Summary
Technical Problem
Existing flexible display devices suffer from flickering issues when displaying at low frequencies, which affects the display effect.
Method used
By employing low-temperature polycrystalline oxide (LTPO) technology and combining a first driving mode and a second driving mode, the driving method of the pixel circuit is optimized by using different types of signals in the refresh frame and the hold frame. This includes voltage control of the data signal line and the initial signal line, thereby achieving constant voltage and alternating voltage variation.
Benefits of technology
It effectively reduces flickering in low-frequency displays, improves display quality, and reduces power consumption.
