AI Technical Summary

Technical Problem

In mobile devices, spatial competition between the camera and the display panel leads to a degradation of image quality, especially when brightness difference and unexpected lines appear at the boundaries between different areas of the display panel, affecting image quality.

Method used

By setting an area including the first and second pixel groups in the display panel and compensating the image data using a compensation circuit, the brightness is adjusted to ensure image quality consistency at the boundary while maintaining high transparency of the second area to facilitate the camera to capture the image.

Benefits of technology

Improves the image quality of the display panel, reduces brightness difference and unexpected lines at the boundary, improves display and image capture performance, while meeting the camera's light transmission needs.

Abstract

An electronic device includes a display panel and a compensation circuit. The display panel includes a first region including a first pixel group and a second region including a second pixel group. The compensation circuit can receive first image data. In response to determining that the first image data corresponds to at least one of one or more specific first pixel groups adjacent to a boundary between the first region and the second region, or one or more specific second pixel groups adjacent to the boundary, the compensation circuit can perform compensation to generate second image data. The compensation circuit outputs the second image data to the display panel.
