Display Panel Data Line Reset Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Insufficient pixel charging time in display panels due to the time required for resetting data lines, which affects the display effect.
Innovation Solution
Implementing a display panel design where at least one data line receives a data signal while simultaneously resetting another data line, allowing the data reset process to overlap with the data writing process of other data lines, thereby extending charging time without occupying additional time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data lines are reset sequentially before data writing, then data lines are properly prepared for data reception, but pixel charging time is insufficient
Solution Approach 1:
The patent applies preliminary action by resetting data lines in advance during the previous row's data writing phase. Specifically, while data is being written to the current row's data lines, the signal writing unit simultaneously writes reset signals to the next row's data lines, preparing them for subsequent data reception without delaying the current charging process
Solution Approach 2:
The patent implements continuity of useful action by overlapping the reset operation with the data writing operation. The signal writing unit continuously writes signals (data or reset) to data lines without idle gaps, ensuring that reset signals are written to data lines during the data writing phase of other data lines, thereby eliminating wasted time and extending effective charging time
2Reliability
If separate reset processes are implemented for data lines, then data lines are properly reset, but charging time is reduced
Solution Approach 1:
The patent merges the reset process with the data writing process by using the same signal writing unit to perform both operations. Reset signals are written to data lines during the data writing phase of other data lines, combining two previously separate processes (reset and data writing) into a single integrated operation that eliminates the need for separate reset time
Solution Approach 2:
The reset operation is performed as a preliminary action during the data writing phase. The signal writing unit writes reset signals to data lines in advance, during the data writing phase of other data lines, so that when those data lines need data, they are already prepared and reset
Data Source
AI summary
Provided are a display panel and a display device. The display panel includes data lines arranged along the row direction, the operation of the data lines includes a data writing phase; and at least one data line meets the following: the at least one data line receives a data signal, while at least one of the other data lines receives a reset signal simultaneously. According to the provided display panel, the data reset process of the at least one data line overlaps with the data writing process of the other data lines.
