Under-Display Pixel Layout for Camera Region Transmittance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices often experience reduced transmittance and visibility in regions where components like cameras are integrated, leading to 'black holes' in the screen.
Innovation Solution
The display device is designed with a first region and a second region, where the second region has a lower density of pixels and wires compared to the first region, allowing for increased transmittance and uniform luminance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pixels and wires are densely arranged in a region, then screen visibility and resolution are improved, but components like cameras cannot be integrated into that region
Solution Approach 1:
The display panel is divided into multiple regions with different pixel densities. A first region has a first pixel density suitable for high-resolution display, while a second region has a second pixel density that allows integration of components such as cameras. This segmentation enables both high screen resolution in the first region and component integration in the second region without mutual interference.
2Adaptability or versatility
If pixels are removed from a region to accommodate components, then component integration is enabled, but screen transmittance and luminance are reduced
Solution Approach 1:
Different regions of the display panel are assigned different pixel densities according to local requirements. The first region maintains high pixel density for optimal luminance and resolution, while the second region uses lower pixel density to accommodate components. This local differentiation ensures that component integration does not unnecessarily reduce overall screen luminance.
3Adaptability or versatility
If wire density is reduced in a region, then component integration is facilitated, but signal transmission quality may be affected
Solution Approach 1:
The display panel is segmented into regions with different wire densities matching the pixel density of each region. The first region has higher wire density for robust signal transmission, while the second region has reduced wire density compatible with component integration. This segmentation ensures signal transmission quality is maintained where needed while enabling component integration where required.

AI summary
A display device includes a first region and a second region each including a plurality of pixels, and a plurality of wires connected to the plurality of pixels, respectively, to transmit a signal, where the number of pixels per unit area in the second region is less than the number of pixels per unit area in the first region, and the number of wires per unit area in the second region is less than the number of wires per unit area in the first region.
