Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If functional elements (camera, sensor, etc.) are arranged on the front face of the display, then the display can perform additional functions (photography, video session, fingerprint recognition), but the screen-to-panel ratio deteriorates and visual effect is compromised
Solution Approach 1:
The patent applies local quality by creating distinct display regions with different pixel densities. The first display sub-area has a first pixel density while the second display sub-area has a second pixel density that is lower than the first. This allows functional elements to be positioned in the lower-density second sub-area where fewer pixels are needed, thereby preserving the screen-to-panel ratio in the high-quality first sub-area while still integrating functional elements into the overall display structure.
2Area of stationary object
If pixel density is reduced in certain areas to accommodate functional elements, then screen-to-panel ratio improves, but display quality in those areas deteriorates
Solution Approach 1:
The patent applies local quality by creating distinct display regions with different pixel densities. The first display sub-area has a first pixel density while the second display sub-area has a second pixel density that is lower than the first. This allows functional elements to be positioned in the lower-density second sub-area where fewer pixels are needed, thereby preserving the screen-to-panel ratio in the high-quality first sub-area while still integrating functional elements into the overall display structure.
Solution Approach 2:
The patent applies segmentation by dividing the display area into multiple distinct sub-areas (first display sub-area and second display sub-area) with different functional requirements and pixel density characteristics. This segmentation allows the display to optimize pixel distribution according to local needs, maintaining high display quality where needed while reducing pixel density in areas dedicated to functional elements.

AI summary
Disclosed are a display substrate, a drive method therefor, a display apparatus, and a high-precision metal mask template, a display region of the display substrate comprising a first display sub-region having high pixel distribution density and a second display sub-region having low pixel distribution density. As the pixel distribution density in the second display sub-region is low, components such as a camera can be arranged in the second display sub-region, thus increasing the screen occupation ratio of the display substrate by means of reducing the local pixel distribution density in order to increase the light transmittance of the screen.
