Transparent Pixel Structure for Under-Display Camera Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses have low light transmittance, which affects the imaging quality of cameras integrated into the device, particularly when the camera is positioned behind the display screen.
Innovation Solution
The display apparatus is divided into distinct areas, with the area corresponding to the camera having higher light transmittance than other areas, incorporating light-transmitting wires and filling blocks with matching optical parameters to minimize diffraction effects, and reflective anodes to enhance both display and imaging capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If driving circuits are disposed on the transparent display region, then the display function is maintained, but the light transmittance rate of the transparent display region deteriorates
Solution Approach 1:
The display region is segmented into a transparent display region and a non-transparent display region. The transparent display region excludes driving circuits to maximize light transmittance, while the non-transparent display region contains the driving circuits. This spatial segmentation resolves the contradiction by allowing the transparent region to maintain high light transmittance while the overall display apparatus still provides complete display functionality through the non-transparent region.
2Measurement precision
If the display screen is made fully transparent to allow camera imaging, then the camera imaging quality improves, but the display brightness and uniformity deteriorate
Solution Approach 1:
Different regions of the display screen are assigned different optical properties. The transparent display region has high light transmittance optimized for camera imaging, while the non-transparent display region has standard display properties optimized for brightness and uniformity. This local differentiation allows the camera to achieve high imaging quality through the transparent region while the non-transparent region maintains excellent display brightness and uniformity.
3Measurement precision
If a light-transmitting display area is created for the front camera, then the camera imaging function improves, but the display area is reduced
Solution Approach 1:
The display screen is divided into transparent and non-transparent regions. The transparent display region serves dual purposes: it functions as a display area and simultaneously serves as the aperture for the front camera. The non-transparent display region provides additional display area. This segmentation allows the camera imaging function to improve without significantly reducing the total effective display area, as the non-transparent region compensates for the transparent region's reduced display capability.
