Solution Overview
Problem
The display quality of display devices is compromised due to a decrease in image resolution in luminance compensation display areas, which affects the ability to simultaneously display images and capture external light effectively.
Innovation Solution
A display device design featuring a luminance compensation display area with a higher light transmittance than normal display areas, utilizing a specific structure of semiconductor patterns, conductive layers, and inorganic insulating layers to enhance light emission and signal transmission, including a shielding electrode and conductive layers that contact the conductive regions through holes, allowing for improved light transmission and image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a display device uses a uniform structure across all display areas, then manufacturing is simple, but light transmittance cannot be optimized for different functional regions
Solution Approach 1:
The patent implements different structural configurations in different display areas: the first display area has a first semiconductor pattern with first source/drain regions and first electrode contacts, while the second display area has a second semiconductor pattern with second source/drain regions and second electrode contacts. This local differentiation allows the first display area to have higher light transmittance while the second display area maintains different electrical connection characteristics, resolving the contradiction between uniform manufacturing simplicity and localized optical optimization.
2Illumination intensity
If the display area is reduced to accommodate additional functional areas, then external light capture is improved, but image display resolution deteriorates
Solution Approach 1:
The patent divides the display device into distinct functional segments: a first display area optimized for light transmission and external light capture, and a second display area with different structural characteristics. By segmenting the display area rather than using a uniform design, the device can simultaneously achieve good light capture capability in the first area while maintaining adequate display resolution through the structured arrangement of semiconductor patterns and electrode contacts in both areas.
3Illumination intensity
If different semiconductor patterns are used in different display areas, then light transmittance is optimized, but manufacturing complexity increases
Solution Approach 1:
The patent employs a unified semiconductor layer that serves multiple functions across different display areas. The same semiconductor layer forms both the first semiconductor pattern in the first display area and the second semiconductor pattern in the second display area. This universal semiconductor layer approach allows different functional configurations to be achieved through selective patterning and contact formation rather than requiring separate semiconductor layers, thereby reducing manufacturing complexity while still optimizing light transmittance in the first display area.
