Under-Panel Display Layout for Higher Camera Light Transmittance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing OLED display apparatuses with camera under panel technology suffer from low light transmittance in the CUP region, which affects the photosensitive effect of elements like cameras and sensors.
Innovation Solution
A display panel design with a light-blocking layer that includes specific opening regions, allowing for greater transmittance in light-transmitting regions compared to pixel regions, and optimizing the distance between these regions to maximize space utilization and light entry for photosensitive elements.

Engineering Contradiction Analysis
1Area of stationary object
If multiple pixels are disposed in the CUP region to achieve full-panel display, then the display coverage is improved, but the light transmittance in the CUP region decreases
Solution Approach 1:
The CUP region is segmented into multiple light-transmitting regions and pixel regions. The light-blocking layer is divided into multiple light-blocking portions that correspond to different pixel regions, allowing selective light transmission and blocking in different areas of the CUP region.
Solution Approach 2:
Different regions within the CUP area are assigned different optical properties. The light-transmitting regions have high light transmittance for camera light entry, while the pixel regions have light blocking capability for display function, creating local quality differentiation to resolve the contradiction between display coverage and light transmittance.
2Illumination intensity
If the distance between light-transmitting region and pixel region is increased to improve light transmission, then the light transmittance is improved, but the space utilization decreases
Solution Approach 1:
The light-blocking layer is positioned in a different dimensional plane (below the display panel) to achieve light blocking without occupying lateral space in the CUP region. This vertical dimensionality change allows the light-transmitting regions to be closely positioned with pixel regions while maintaining effective light transmission paths.

AI summary
A display panel and a display apparatus are provided in the present disclosure. The display panel includes a first display region and a light-blocking layer. The first display region includes a plurality of light-transmitting regions and a plurality of pixel regions; and a transmittance of a light-transmitting region is greater than a transmittance of a pixel region. The light-blocking layer includes a first opening region and a second opening region; along a direction perpendicular to a plane of the display panel, the first opening region is overlapped with the light-transmitting region, and the second opening region is overlapped with the pixel region; and along a direction in parallel with the plane of the display panel, a minimum distance between the light-transmitting region and the pixel region is D1, and a minimum distance between two adjacent pixel regions is D2, where D1<D2.
