Display Panel Light-Transmitting Region for Camera Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for high screen ratio in display devices is hindered by the need to accommodate a front camera, which typically requires a physical through-hole in the display screen, reducing the screen ratio and affecting the display area.
Innovation Solution
A display panel design featuring a main light-transmitting region surrounded by pixel units and an electrical control layer, where the orthographic projection of the light-transmitting region does not overlap with pixel units or metal wiring, allowing external light to pass through and be received by an image acquisition device without a physical through-hole, and optionally including auxiliary light-transmitting regions for enhanced light transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a physical through-hole is set in the display area to accommodate the front camera, then the camera function is achieved, but the screen ratio decreases
Solution Approach 1:
The patent extracts the light-transmitting function from the traditional through-hole structure and relocates it to a dedicated light-transmitting region. This separates the camera function from the display area, allowing the display to maintain its integrity while providing a specific zone for light transmission to the camera sensor.
Solution Approach 2:
The patent transitions from a two-dimensional through-hole concept to a three-dimensional light-transmitting region that extends through multiple layers of the display panel. This vertical integration allows light to pass through the dedicated region to reach the camera sensor without compromising the display area.
2Area of stationary object
If the light-transmitting region area is minimized to maintain high screen ratio, then screen ratio is improved, but light transmission efficiency may be reduced
Solution Approach 1:
The patent applies local quality by creating a dedicated light-transmitting region with specific optical properties in a localized area, while the rest of the display maintains its normal display characteristics. The light-transmitting region is strategically positioned and sized to balance screen ratio and light transmission efficiency.
Solution Approach 2:
The patent optimizes parameters such as the area, shape, and position of the light-transmitting region to achieve the best balance between screen ratio and light transmission efficiency. By carefully controlling these parameters, the design ensures sufficient light reaches the camera sensor while maintaining a high screen ratio.

AI summary
A display panel and a display device are provided, and the display panel includes a substrate and a pixel layer disposed on the substrate. The pixel layer includes a plurality of pixel units arranged in an array. The display panel includes a main light-transmitting region surrounded by the plurality of pixel units, and an orthographic projection of the main light-transmitting region on the substrate is not overlapped with orthographic projections of the plurality of pixel units on the substrate, so that external light is allowed to pass through the main light-transmitting region of the display panel, and then is received by an image acquisition device disposed on a side of the display panel.
