Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple signal lines are used to independently control pixels of different colors, then independent control capability is improved, but layout space is increased
Solution Approach 1:
The patent merges the control functions for different color pixels into a single emission control circuit that processes multiple emission signals sequentially. Instead of having separate control lines for each color, the circuit integrates the control logic to handle red, green, and blue pixels through time-division, thereby reducing the number of physical signal lines required while maintaining independent control capability.
Solution Approach 2:
The emission control circuit operates periodically by sequentially processing emission signals for different colors in a time-division manner. The circuit receives multiple emission signals corresponding to different colors and processes them in periodic cycles, allowing independent control of each color's emission timing without requiring simultaneous separate control lines for all colors.
2Manufacturing precision
If multiple control signals are used to independently adjust emission times, then emission control precision is improved, but wiring layout area is increased
Solution Approach 1:
The patent combines multiple emission control signals into a single integrated control path within the emission control circuit. The circuit receives multiple emission signals for different colors and integrates their control logic, allowing precise adjustment of emission times for each color through a unified control mechanism rather than through separate wiring paths for each color.
Solution Approach 2:
The emission control circuit dynamically adjusts the emission timing for different colors by processing emission signals in a time-division manner. The circuit can flexibly control the emission period of each color pixel independently by manipulating the timing of emission signals in sequence, achieving precise control without requiring static separate control lines for each color.

AI summary
A display panel is provided. The display panel includes multiple emission circuits, multiple emission control circuits, multiple pixel circuits, and multiple emission control lines. The emission circuit receives multiple clock signals to provide multiple emission signals. The emission control circuit receives one of the emission signals and receives multiple emission control signals to provide multiple pixel emission signals based on the received emission signal and the emission control signals. The pixel circuits are arranged in an array. The emission control lines are respectively coupled to one of the emission control circuits and pixel circuits of a same color among the pixel circuits in a row to transmit a corresponding one of the pixel emission signals to the coupled pixel circuits.
