Display Panel Encapsulation Opening for Protected Driver Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The exposure of wirings between the display driver and the display area in display panels can lead to damage and instability in the connection between the display controller and the display panel, causing malfunctions and complicating the structure.
Innovation Solution
A display panel design that includes a substrate with a protrusion and an encapsulation member defining an opening to shield the display layer, with a display controller recessed away from the substrate protrusion and connected via a connection member, reducing the exposure of wirings and ensuring a robust connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wirings are exposed between the display driver and display area, then the structure is simpler and easier to manufacture, but the wirings may be damaged and the connection becomes unstable
Solution Approach 1:
The encapsulation member is segmented to include a specific opening that exposes only the display driver while covering the wirings. This selective segmentation allows the wirings to be protected from damage while maintaining connection stability, resolving the contradiction between reliability and structural simplicity.
Solution Approach 2:
The encapsulation member acts as an intermediary element that mediates between the exposed display driver and the protected wirings. By introducing this intermediate protective structure, the patent achieves stable connections without requiring complete wiring exposure, thus improving reliability while accepting moderate structural complexity.
2Reliability
If the display controller is connected to the display panel, then signal transfer is enabled, but the connection structure becomes complicated and power supply stability decreases
Solution Approach 1:
The display controller is extracted from the display panel structure and positioned separately. This extraction eliminates the need for complex internal connection structures within the panel while maintaining signal transfer capability. The separate positioning also improves power supply stability by reducing interference and connection points, thus resolving the contradiction between reliability and structural complexity.
Solution Approach 2:
Instead of integrating the display controller directly into the panel with complex connections, the patent uses a simplified connection interface that copies only the essential signal transfer function. This approach reduces the connection structure complexity while maintaining the necessary power supply stability and signal transfer capability.
3Reliability
If the encapsulation member covers the entire display layer, then protection is maximized, but the display driver cannot be accessed for connection
Solution Approach 1:
The encapsulation member is segmented with a strategically positioned opening that allows the display driver to be accessed while the rest of the display layer remains fully protected. This segmentation enables both maximum protection and driver accessibility, resolving the contradiction between reliability and ease of operation.
Solution Approach 2:
The encapsulation member exhibits local quality by providing full coverage protection to the display layer while creating a localized opening for driver access. This localized modification maintains high protection effectiveness overall while enabling necessary accessibility operations, thus resolving the contradiction between reliability and ease of operation.
