Display Panel Light-Shielding Layout for Uniform Reflectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices experience a display effect difference between light collection areas and other areas due to reflectivity differences, affecting user viewing experience, as light sensors are primarily located on non-display surfaces and require specific light transmittance for light collection.
Innovation Solution
A display panel design with a substrate, light-emitting layer, and light-shielding layer featuring first and second light-transmitting holes in non-opening areas of respective display areas, ensuring equal reflectivity and reducing display differences by positioning light-transmitting holes in non-opening areas of both light collection and non-collection areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a light collection area is set in the display area to enable light acquisition functions, then the display device can perform image acquisition or fingerprint recognition, but there is a display effect difference between the light collection area and other display areas
Solution Approach 1:
The patent applies local quality by configuring different light-transmitting hole patterns in different regions of the light-shielding layer. Specifically, the first light-transmitting holes are arranged in the first light-shielding layer while second light-transmitting holes are arranged in the second light-shielding layer, creating region-specific optical properties that enable both light collection functionality and uniform display effect across different display areas.
Solution Approach 2:
The light-shielding layer is segmented into multiple regions (first light-shielding layer and second light-shielding layer) with different light-transmitting hole configurations. This segmentation allows independent optimization of each region's optical properties, enabling the light collection area to have different characteristics from other display areas while maintaining overall display uniformity.
2Use of energy by moving object
If light-transmitting holes are configured in the light-shielding layer to enable light transmission, then light collection function is achieved, but reflectivity difference between light collection area and non-light collection area increases
Solution Approach 1:
Different light-transmitting hole patterns are implemented in different light-shielding layers to achieve local optimization of light transmission and reflectivity. The first light-transmitting holes in the first light-shielding layer and second light-transmitting holes in the second light-shielding layer create region-specific optical characteristics that balance light transmission efficiency with reflectivity uniformity.
Solution Approach 2:
The patent introduces a multi-layer dimension to the light-shielding structure, with light-transmitting holes distributed across different layers (first light-shielding layer and second light-shielding layer). This dimensional approach allows independent control of light transmission and reflectivity properties by configuring holes at different depths, thereby resolving the contradiction between light transmission efficiency and reflectivity uniformity.
