AI Technical Summary
As display resolution increases, the data transmission rate of the data driver chip increases, leading to increased power consumption, heat generation, and temperature rise. Furthermore, differences in transmission delay caused by variations in data line resistance affect the display effect and can easily result in vertical stripe issues.
The control unit triggers image and clock conversion operations to convert the image frame to be displayed into the target image frame. The gate scanning signal and data signal are output through the gate driving unit and the data driving unit. The voltage change amplitude of the data signal is controlled to be less than the first threshold, thereby extending the transition period of the data signal and preventing the data voltage of the data driving chip from changing rapidly.
The power consumption of the driver chip was reduced, the temperature rise was decreased, the display effect was improved, and the problem of vertical stripes under heavy load was solved.
