1Area of stationary object
If traditional conductive structures are used to connect different conductive layers in pixel arrays, then electrical connection between common electrodes is achieved, but the aperture ratio is restricted due to the large area occupied by conductive structures
Solution Approach 1:
The patent merges the connection function of multiple conductive structures into a shared conductive structure. The first common electrode and third common electrode are connected through a shared conductive structure that serves both pixel units, reducing the total number of conductive structures and increasing the aperture ratio while maintaining electrical connectivity.
Solution Approach 2:
The shared conductive structure performs multiple functions: it connects the first common electrode to the third common electrode, and also provides a common reference potential for multiple pixel units. This multi-functional design reduces the number of dedicated conductive structures needed for each pixel unit.
2Reliability
If multiple conductive structures are used to connect common electrodes in each pixel unit, then electrical connection is ensured, but the manufacturing complexity and area occupation increase
Solution Approach 1:
Adjacent pixel units share common conductive structures for connecting common electrodes. The first conductive structure connects the first common electrode to the second common electrode, while the third conductive structure connects the third common electrode to the fourth common electrode, with shared structures between adjacent pixel units, reducing manufacturing steps and complexity.
Solution Approach 2:
The conductive structures are segmented into pixel-unit-specific portions and shared portions. Each pixel unit has its own pixel electrode connections, while the common electrode connections are segmented to be shared between adjacent pixel units, optimizing both reliability and manufacturability.
