Display Pixel Layout for Under-Panel Camera Transmittance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices often experience reduced transmittance and visibility due to the presence of components like cameras, which are not integrated into the pixel array, resulting in 'black holes' on the screen and interference with image viewing.
Innovation Solution
A display device design with a first region for pixel display and a second region for component integration, where the number of pixels and wires is reduced in the second region, allowing for increased transmittance and luminance without affecting component function, and including a light blocking member to form an auxiliary capacitor.

Engineering Contradiction Analysis
1Adaptability or versatility
If components like cameras are disposed in regions surrounded by pixel display regions, then component integration is achieved, but transmittance is reduced and black holes appear on the screen
Solution Approach 1:
The display device is divided into a first region with a first pixel density and a second region with a second pixel density, allowing different areas to have different characteristics. The second region, where components are disposed, has a lower pixel density which reduces the blocking effect and improves transmittance while the first region maintains high pixel density for normal display quality.
2Adaptability or versatility
If components like cameras are disposed in regions surrounded by pixel display regions, then component integration is achieved, but image viewing is interfered with due to black holes
Solution Approach 1:
Different regions of the display device are given different pixel densities according to their specific functions. The second region where components are disposed has a lower pixel density (one sixth or more and half or less of the first region), which creates a visual transition that reduces the black hole effect and improves overall image viewing experience while maintaining component integration.
3Illumination intensity
If the number of pixels per unit area is reduced in the second region, then transmittance is increased, but display resolution may be affected
Solution Approach 1:
The display area is segmented into multiple regions with different pixel densities. The second region has a reduced pixel density (one sixth or more and half or less of the first region) which increases transmittance and reduces the black hole effect, while the first region maintains high pixel density to ensure overall display resolution is not significantly compromised.
4Illumination intensity
If the number of wires per unit area is reduced in the second region, then transmittance is increased, but signal transmission capability may be affected
Solution Approach 1:
Multiple initialization voltage supply lines (both first and second initialization voltage supply lines) are merged into a single consolidated wiring structure in the second region. This reduces the number of wires per unit area, increases transmittance, and simplifies the wiring complexity while maintaining the necessary signal transmission capability through the combined voltage supply.

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.
