AI Technical Summary

Technical Problem

In miniaturized display panels, the pulse width of the nth stage driving signal exceeds 1H, causing the waveform to cross the change edge of the enable signal, resulting in partial refresh failure due to incomplete output of the nth stage driving signal.

Method used

A driving circuit comprising a driving signal generation circuit, control signal generation circuit, and control circuit, with additional components like output inverter circuits and energy storage circuits, to accurately control and invert signals, ensuring complete output of the nth stage driving signal.

Benefits of technology

The solution enables accurate partial refresh operations in display panels by precisely controlling and inverting signals, preventing abnormal pixel operations and ensuring complete signal output.

Abstract

The device comprises a drive circuit, a display board, and a display device. The drive circuit includes a drive signal generation circuit (11), a control signal generation circuit (12), and a control circuit (13). The drive signal generation circuit (11) is for generating the nth stage drive signal, where n is a positive integer. The control signal generation circuit (12) is for generating a control signal according to an enable signal. The control circuit (13) is for outputting the nth stage drive signal or an reactive voltage signal to the nth stage drive output terminal under the control of the control signal. Because the drive circuit can accurately output the nth stage drive signal or an reactive voltage signal to the nth stage drive output terminal, partial refresh can be performed accurately.
