Solution Overview
Problem
Display devices face challenges in integrating components like cameras or sensors while maintaining high light transmittance and efficient operation, especially with the trend towards thinner and larger display areas.
Innovation Solution
A display device design with a substrate that includes a high light transmittance area for components, featuring a non-display area allowing light transmission and a zigzag pattern of lines connected to pixels, with disconnection points to optimize space utilization and reduce RC delay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If non-display areas are integrated into the display device to accommodate components such as cameras or sensors, then component functionality is improved, but the planar area available for display purposes is reduced
Solution Approach 1:
The patent moves the non-display area containing components (camera, sensor, etc.) from the planar display surface to a spatial dimension below the display area. This is achieved by positioning the component on a lower substrate that is disposed below the display area, allowing light to pass through the display area from the component. This dimensional transition resolves the contradiction by accommodating components without reducing the planar display area.
2Reliability
If non-display areas are created within the display area for component placement, then component operation is improved, but light transmittance is reduced
Solution Approach 1:
The patent positions the non-display area in a lower dimension below the display area rather than within it. The component is disposed on a lower substrate below the display area, and light passes through the display area to reach the component. This spatial arrangement allows the display area to maintain high light transmittance while the component operates effectively in the lower dimension.
Solution Approach 2:
The patent introduces a lower substrate as an intermediary structure that supports the component (camera, sensor, etc.) below the display area. This lower substrate acts as a mediator that enables component placement without interfering with light transmission through the display area, thus maintaining both component operation reliability and light transmittance.
3Area of stationary object
If the display area is enlarged to occupy more planar area, then display functionality is improved, but the area available for integrating connecting functions is reduced
Solution Approach 1:
The patent relocates the connecting functions (camera, sensor, and their interconnections) from the planar display area to a lower dimension. The component providing connecting functions is disposed on a lower substrate below the display area, allowing the display area to be enlarged while maintaining adaptability for connecting functions through vertical spatial utilization.
