Variable Density Display Panel for Under-Display Camera Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panel designs face challenges such as increased failure rates, thickness, and dust accumulation due to the integration of front operating apparatuses like cameras, which also affect the screen-to-body ratio and display quality.
Innovation Solution
A display panel design featuring a base substrate with distinct regions: a low-display-density region, a transition region, and a high-display-density region, where the low-display-density region has a lower pixel density to accommodate the operating apparatus, ensuring optimal light collection and reducing the need for mechanical lifting or sliding mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the operating apparatus is disposed under the screen with reduced opening, then the screen-to-body ratio is increased, but the display quality deteriorates and the operating apparatus cannot operate normally
Solution Approach 1:
The display panel is divided into different display density regions: a first display density region with higher pixel density for normal display areas, and a second display density region with lower pixel density where the operating apparatus is located. This local differentiation allows the screen-to-body ratio to be increased while maintaining display quality in non-critical areas and ensuring proper light transmission for the operating apparatus underneath.
2Area of moving object
If electric lifting or push-pull slide-type mechanisms are used for the front camera, then the screen-to-body ratio can be maintained, but the device thickness and weight increase along with failure rate
Solution Approach 1:
The invention extracts the operating apparatus from the mechanical lifting or sliding structure and places it directly underneath the display panel in a fixed position. By creating a specific low-display-density region beneath the operating apparatus, the design eliminates the need for complex mechanical mechanisms while maintaining the screen-to-body ratio, thereby reducing device thickness, weight, and potential failure points.
3Measurement precision
If the display density is uniformly high across the entire screen, then the display quality is maximized, but the operating apparatus cannot function properly due to insufficient light transmission
Solution Approach 1:
The display panel employs spatially varying pixel density: high display density in the first region for optimal visual quality, and low display density in the second region beneath the operating apparatus to allow sufficient light transmission. This local quality differentiation ensures that display quality is maximized where needed while enabling the operating apparatus to function properly underneath.

AI summary
A display panel (10) and an electronic device are provided. The display panel (10) includes a base substrate, a low-display-density region (200), a transition region (300) and a high-display-density region (400), the low-display-density region (200), the transition region (300) and the high-display-density region (400) being located on the base substrate. The transition region (300) is located between the low-display-density region (200) and the high-display-density region (400). The low-display-density region (200), the transition region (300) and the high-display-density region (400) are provided with pixel units (101) for emitting light, respectively. A display density of the low-display-density region (200) is less than a display density of the transition region (300), and the display density of the transition region (300) is less than a display density of the high-display-density region (400). Therefore, a clear border between the high-display-density region (400) and the low-display-density region (200) is avoided, and a display effect of the display panel (10) and the electronic device is ensured.
