Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels face a challenge in achieving full-screen displays due to the need for a camera area, which results in diffraction light spots when light passes through the gaps between pixel units, compromising image quality and display effect.
Innovation Solution
Incorporating at least two image capturing regions in the display area with driving circuits and metal traces, and using image capturing components to capture images from these regions, processing them with an algorithm to eliminate diffraction light spots, thereby improving display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the camera area is used for display by arranging pixel units, then the screen proportion and aesthetic are improved, but diffraction light spots occur due to gaps between pixel units
Solution Approach 1:
The display area is segmented into multiple independent image capturing regions, each with its own pixel units arranged in arrays. By dividing the camera area into multiple regions (e.g., first and second image capturing regions), the patent enables display functionality while managing the diffraction issue through regional separation and independent control of pixel arrangements in each segment.
2Adaptability or versatility
If pixel units are arranged neatly in the camera area, then the display function is achieved, but slender gaps form between pixel units causing light diffraction
Solution Approach 1:
Different image capturing regions have different local characteristics - each region's pixel units are arranged with specific gap patterns that create different diffraction characteristics. The first image capturing region has pixel units with gaps producing certain diffraction light spots, while the second region has pixel units with different gap arrangements producing different diffraction patterns, allowing local optimization of display quality while managing diffraction effects.
3Device complexity
If a single image capturing region is used, then the structure is simple, but diffraction light spots cannot be eliminated effectively
Solution Approach 1:
The patent merges multiple image capturing regions with different diffraction characteristics into a single display system. By combining the first and second image capturing regions, each with distinct pixel arrangements and diffraction patterns, the system achieves effective elimination of diffraction light spots through algorithmic processing that leverages the complementary nature of the different regions' optical characteristics.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach allows for a full-screen display without diffraction light spots, maintaining consistent pixel density and enhancing the overall display effect by eliminating diffraction issues.
Implementation Method 1
a slender gap is formed between neatly arranged pixel units, which is prone to diffraction of light, resulting in light spots when taking pictures or taking videos

AI summary
Disclosed are a display panel and a display device. By setting at least two image capturing regions and providing at least two image capturing components corresponding to the at least two image capturing regions respectively, the at least two image capturing components capture images through the at least two image capturing regions to obtain at least two images, and process the at least two images to eliminate a plurality of diffraction light spots, so as to obtain a final image without the diffraction light spots, thereby improving a display effect.
