Display panel driving method, display panel, device and storage medium

By determining the corresponding multiple N of the row in the stacked architecture and delaying the scan line of the secondary display screen, and combining the scroll cache data of the row cache unit to calculate the luminous intensity, the display anomaly caused by the data delay of the secondary display screen is solved, and the synchronous display of the primary and secondary displays is realized.

AI Technical Summary

Technical Problem

In a stacked architecture, the secondary display screen experiences a display anomaly due to a one-frame data delay.

Method used

By determining the row correspondence multiple N between the main display screen and the secondary display screen, the second row of the secondary display screen is delayed by two rows, and the target pixel data is buffered in the row buffer unit. The luminous intensity of the target scan row of the secondary display screen is calculated, and the secondary display screen is driven to display based on the delayed two rows of scan lines.

Benefits of technology

It achieves synchronized display between the main display screen and the secondary display screen, avoiding display abnormalities caused by a one-frame data delay on the secondary display screen, and making the display of dynamic images smoother.

Abstract

This application relates to a display panel driving method, display panel, device, and storage medium. The method determines the line correspondence multiple N between the main display screen and the secondary display screen based on their resolutions. The main display screen is driven to display according to the first data line of the main display screen based on the first scan line, while the second scan line of the secondary display screen is delayed by two lines. The target pixel data of the first scan line is buffered in a row buffer unit. The target pixel data includes at least the first pixel data corresponding to the current scan line of the main display screen and the second pixel data corresponding to the 2N-1 lines following the current scan line. The luminance of the target scan line of the secondary display screen corresponding to the current scan line of the main display screen is calculated based on the target pixel data. The target scan line of the secondary display screen is driven to display according to the luminance based on the second scan line that is delayed by two lines. This eliminates the need for a one-frame delay in the secondary display screen, avoiding display anomalies.
