Solution Overview

Problem

Inconsistent pixel densities between display areas in terminals, such as those with a camera under panel (CUP), result in poor user experience due to varying visual display effects.

Innovation Solution

Extracting image texture data from one display area and performing pixel mapping to achieve consistent visual display effects across areas with different pixel densities, without altering the original pixel density, thereby maintaining functional requirements like high-transparency image capturing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a camera under panel (CUP) scheme is used to improve image capturing effect, then transparency is improved, but pixel density becomes inconsistent with other display areas, resulting in poor visual display effects

Engineering Contradiction:
ImprovetransparencyVSAvoidpixel density consistency
Core Design Contradiction:
Illumination intensityVSManufacturing precision

Solution Approach 1:

The patent applies parameter changes by dynamically adjusting the pixel density parameter of the CUP display area. The system detects the actual pixel density of the CUP area and compares it with adjacent display areas, then adjusts the rendering parameters (such as scaling factors, texture filtering, or pixel sampling rates) to compensate for the density difference. This allows the CUP area to maintain its high transparency while achieving visual consistency with other display areas that have different pixel densities.

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If pixel density is increased to improve visual display effects, then visual quality is improved, but the image capturing effect and transparency of the CUP area are compromised

Engineering Contradiction:
Improvevisual display consistencyVSAvoidtransparency
Core Design Contradiction:
Manufacturing precisionVSIllumination intensity

Solution Approach 1:

The patent applies local quality by implementing display area-specific rendering strategies. The system identifies the CUP area as a special region with different pixel density characteristics and applies customized rendering parameters only to that local area, while other display areas use their standard rendering parameters. This local adaptation allows the CUP area to maintain its high-transparency image capturing function while achieving visual consistency with surrounding areas, without compromising the overall transparency of the CUP region.

Inventive Principle:
Principle #3Local quality

AI summary

The disclosure relates to a display control method, a display control device, and a computer-readable storage medium. The display control method is applied to a terminal including a first display area and a second display area with different pixel densities. The display control method includes: image texture data of the first display area is extracted (S11); a pixel mapping is performed on the image texture data to enable the first display area and the second display area to obtain consistent visual display effects (S12); and the image texture data of the first display area is updated to the pixel-mapped image texture data for displaying (S13). Through the disclosure, it is possible to achieve consistent visual display effects of display areas with inconsistent pixel densities.
