Pixel Circuit Wire Sharing for Display Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional pixel circuits require more signal lines due to the need for multiple wires as control signal lines and input signal lines, leading to increased pixel area and reduced display resolution.
Innovation Solution
The proposed pixel circuit design includes a second wire shared by the control terminal of the first light-emitting control unit and the compensation unit, reducing the number of wires needed and improving display resolution. Additionally, the compensation unit is connected to the driving unit to reduce leakage paths and currents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each transistor is equipped with separate control signal lines and input signal lines, then the control and operation of each transistor is ensured, but the number of signal lines increases, resulting in increased pixel area
Solution Approach 1:
The patent merges the control signal lines of multiple transistors into a shared wire. Specifically, the control terminal of the first light-emitting control unit and the control terminal of the compensation unit share a common control signal line, reducing the total number of signal lines required in the pixel circuit while maintaining proper control of each transistor
Solution Approach 2:
The shared control signal line serves multiple functions by simultaneously controlling both the first light-emitting control unit and the compensation unit. This multi-functional approach allows a single wire to perform what traditionally required separate dedicated lines for each transistor
2Ease of operation
If more signal lines are used to ensure proper transistor control, then the control functionality is improved, but the display resolution is reduced due to increased pixel area
Solution Approach 1:
By combining control signal lines into shared wires, the patent reduces the number of interconnects required in each pixel, thereby reducing pixel area and enabling higher display resolution while maintaining complete control functionality for all transistors through the shared signaling approach
3Reliability
If the compensation unit is connected with multiple wires, then the control and compensation functionality is ensured, but the number of wires increases, which is not conducive to improving display resolution
Solution Approach 1:
The compensation unit's control terminal shares a control signal line with the first light-emitting control unit, merging their control pathways. This reduces the wire count for the compensation unit from a dedicated separate line to a shared line, maintaining compensation functionality while reducing pixel area

AI summary
The present disclosure discloses a pixel circuit and a display panel. The pixel circuit comprises a second wire, a first light-emitting control unit, a driving unit, and a compensation unit. A control terminal of the first light-emitting control unit and a control terminal of the compensation unit share the second wire, which can save a wire quantity of the pixel circuit, thereby improving display resolution; at the same time, a control terminal of the driving unit is only equipped with the compensation unit, which reduces a leakage path of the control terminal of the driving unit.
