Scan Signal Conversion Circuit for High-Resolution Display Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the resolution of electronic devices increases, the width and length of scan lines become shorter, leading to susceptibility of scan signals to delay or distortion due to resistance and capacitance, which can cause abnormal operations of electronic circuits.
Innovation Solution
The implementation of a scan signal conversion circuit that converts first scan signals into second scan signals, adjusting them to mitigate delays and distortions, ensuring normal operation of electronic circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the resolution of the electronic device is increased, then the display quality is improved, but the scan line becomes shorter and the scan signal becomes susceptible to delay or distortion
Solution Approach 1:
The patent divides the scan signal transmission path into multiple segments by introducing scan signal conversion circuits at different locations along the scan line. Each conversion circuit independently processes and regenerates the scan signal, effectively segmenting the long transmission path into shorter segments that are less susceptible to RC delay and distortion effects.
Solution Approach 2:
The scan signal conversion circuit acts as an intermediary between the scan line and the electronic circuits. It receives the degraded scan signal from the scan line, converts it back to a clean signal with proper timing characteristics, and then provides it to the electronic circuits, thereby mediating the signal degradation problem.
2Productivity
If the scan line length is reduced to achieve higher resolution, then the display density is improved, but the scan signal experiences greater delay and distortion
Solution Approach 1:
The scan signal conversion circuits perform preliminary signal regeneration and timing adjustment before the scan signal reaches the electronic circuits. By proactively compensating for expected delays and distortions in advance, the circuits ensure that the scan signal arrives at the electronic circuits with correct timing, preventing operational abnormalities.
Solution Approach 2:
The patent changes the timing parameters and voltage levels of the scan signal through the conversion circuits. These circuits adjust the scan signal parameters (such as pulse width, amplitude, and timing) to compensate for the effects of reduced scan line length and higher display density requirements, maintaining signal integrity despite the physical constraints.
