Display Panel Pixel Segmentation for Full-Screen Camera Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies face challenges in implementing a full-screen display due to the presence of front cameras, which restrict screen size and require compromises such as reduced pixel density or light interference from touch sensors.
Innovation Solution
A display panel design with separate pixel areas, one for light emitting elements and another for optical sensors, using transparent extension lines to maintain pixel density and avoid light interference, combined with touch and optical sensor drivers to recognize inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a front camera is added to a smartphone, then multimedia capabilities are improved, but the screen size is reduced and full-screen display cannot be realized
Solution Approach 1:
The patent embeds the camera module within the display panel structure by placing the camera sensor behind the display area. The camera module is nested within the display panel's layered structure, allowing the camera to be positioned at a specific depth level without occupying additional external space, thereby enabling full-screen display while maintaining camera functionality
2Area of stationary object
If the camera module is disposed to overlap with the screen, then full-screen display is implemented, but pixel density is lowered in the overlapping area
Solution Approach 1:
The patent divides the display panel into multiple pixel areas at different depth levels. The first pixel area contains display pixels for normal viewing, while the second pixel area contains camera pixels for camera functionality. This segmentation allows each area to be optimized independently, maintaining high pixel density in the display area while dedicating a separate depth level for camera sensors
3Object-affected harmful factors
If touch sensor wires are removed from the second pixel area, then light interference is reduced, but touch sensitivity cannot be maintained in that area
Solution Approach 1:
The patent resolves the conflict between light transmission and touch sensitivity by adding a depth dimension. The touch sensor layer is positioned at a different depth level (z-axis) than the camera module, allowing touch functionality to be maintained through the third dimension while the camera area remains optically clear in the display plane. This multi-layered approach enables both camera and touch functions to coexist without compromising either
