AI Technical Summary

Technical Problem

OLED displays suffer from insufficient low-latency performance in high-resolution, high-refresh-rate scenarios, resulting in image ghosting, trailing, and uneven brightness, which affect the user's visual experience and operational feedback.

Method used

By receiving a continuous image input stream through the display interface, pixel parsing is performed to construct a pixel state stream. The stream is then scanned line by line and written to the storage capacitor. Drive current compensation and emission window period constraints are then applied to generate an emission enable signal, thereby achieving short-time synchronous emission processing.

Benefits of technology

Reduce inter-frame latency and visual ghosting, improve the smoothness of dynamic images and display accuracy, reduce brightness abrupt changes and response time, improve grayscale linearity and dynamic image clarity, while reducing power consumption and extending OLED lifespan.

Abstract

The present application relates to the field of display screen delay optimization, and particularly relates to a low-delay transmission method, device and equipment of OLED display screen, and a storage medium. The method comprises the following steps: receiving a continuous display image input stream based on a display interface, performing pixel analysis, and constructing a pixel state stream; writing the pixel state stream into a storage capacitor in a pixel driving unit row by row, and marking as a pre-light state; performing driving current compensation on the pixel state stream based on the pre-light state, to obtain a light compensation current; performing light window period constraint based on the display image input stream, to output a short-time light window; generating a light enable signal based on the light compensation current and the short-time light window; and driving the pixel driving unit based on the light enable signal to perform short-time synchronous light processing. The present application realizes low-delay and low-energy-consumption display screen image transmission processing.
