Solution Overview

Problem

Display panels with integrated sensor modules suffer from inconsistent display effects due to differing sub-pixel densities in normal and semi-transparent regions, leading to noticeable boundaries and poor overall display quality.

Innovation Solution

A method for driving a display panel that divides the image into specific partition pictures for different regions, adjusting sub-pixel densities and luminance to create a seamless transition between regions, using a transition region with intermediate sub-pixel density and luminance to bridge the normal and semi-transparent regions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If light emitting elements are disposed in the sensor module region to meet high screen ratio, then the screen ratio is improved, but the display effect becomes inconsistent with normal display region due to lower sub-pixel density

Engineering Contradiction:
Improvescreen ratioVSAvoiddisplay effect consistency
Core Design Contradiction:
Area of stationary objectVSManufacturing precision

Solution Approach 1:

A transition region is introduced between the normal display region and the sensor module display region. This transition region contains light emitting elements with intermediate density that bridges the gap between the two regions, making the boundary less obvious and improving overall display quality while maintaining the high screen ratio

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If sub-pixel density is reduced in the sensor module region to ensure sensor work, then sensor functionality is improved, but display quality deteriorates due to obvious boundaries

Engineering Contradiction:
Improvesensor module functionalityVSAvoiddisplay quality
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The display panel is divided into different regions with different sub-pixel densities: the normal display region has high density for excellent display quality, the sensor module region has low density for sensor functionality, and the transition region has intermediate density to bridge the two regions and reduce boundary visibility

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The transition region acts as an intermediary between the high-density normal display region and the low-density sensor module region, using intermediate sub-pixel density to make the transition gradual and less noticeable, thereby improving overall display quality while maintaining sensor functionality

Inventive Principle:
Principle #24Intermediary (Mediator)

3Manufacturing precision

If sub-pixel density is increased in the normal display region to improve display quality, then display quality is improved, but the boundary with sensor module region becomes more obvious

Engineering Contradiction:
Improvedisplay qualityVSAvoidboundary consistency
Core Design Contradiction:
Manufacturing precisionVSStability of the object's composition

Solution Approach 1:

Different regions are assigned different sub-pixel densities according to their functional requirements: high density in the normal display region for excellent display quality, low density in the sensor module region for sensor functionality, and intermediate density in the transition region to bridge the two

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The transition region with intermediate sub-pixel density serves as a buffer between the high-density normal display region and the low-density sensor module region, creating a gradual transition that reduces the visibility of boundaries and improves overall composition consistency

Inventive Principle:
Principle #24Intermediary (Mediator)
