Display Panel Luminance Correction for Camera Region Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Light-emitting display apparatuses with integrated cameras suffer from image quality degradation due to interference from wiring lines, resulting in luminance differences between camera and normal regions, making the camera region appear dimmer.
Innovation Solution
A method and apparatus that correct input image data using white and monochromatic correction values based on luminance differences between camera and normal regions, ensuring uniform image brightness across the display.

Engineering Contradiction Analysis
1Object-affected harmful factors
If pixel density in camera region is reduced to minimize interference from wiring lines, then camera image quality is improved, but luminance uniformity between camera region and normal region deteriorates
Solution Approach 1:
The patent applies different pixel densities to different regions of the display panel. Specifically, the camera region has a first pixel density while the non-camera region has a second pixel density that is different from the first. This local differentiation allows the camera region to have reduced wiring interference while the non-camera region maintains higher resolution, thereby resolving the contradiction between reducing interference and maintaining luminance uniformity.
2Object-affected harmful factors
If different pixel densities are used in camera and normal regions, then camera image quality is improved, but image uniformity across the display deteriorates
Solution Approach 1:
The patent implements local quality by assigning different pixel densities to different spatial regions. The camera region uses a first pixel density optimized for camera functionality, while the non-camera region uses a second pixel density for optimal display quality. This regional differentiation maintains overall image uniformity while allowing local optimization for camera performance.

AI summary
A method of correcting input image data for a display device can include receiving input image data by a controller in the display device, a first portion of the input image data corresponding to a first region of a display panel in the display device and a second portion of the input image data corresponding to a second region of the display panel having a pixel density different than a pixel density of the first region; and correcting, by the controller, at least some of the input image data to generate corrected image data based on at least one white correction value or at least one monochromatic correction value.
