LCD Panel Sub-Pixel Layout for Crosstalk Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LCD panels experience mura phenomenon and increased power consumption due to crosstalk effects caused by insufficient response time of sub-pixels when displaying high-resolution images, particularly with alternate black and white patterns.
Innovation Solution
The LCD panel is designed with a sub-pixel array where odd and even rows are connected to odd and even-numbered data lines, respectively, and uses a column-inversion or dot-inversion driving method to neutralize voltage coupling effects, reducing the number of data driving chips and eliminating crosstalk.

Engineering Contradiction Analysis
1Ease of manufacture
If the number of data lines is reduced to decrease the number of data driving chips, then manufacturing cost is reduced, but the response time of sub-pixels becomes insufficient leading to crosstalk effect and mura phenomenon
Solution Approach 1:
The invention divides the data lines into two separate groups: first data lines connected to even-numbered gate lines and second data lines connected to odd-numbered gate lines. This segmentation allows independent control and optimization of each group, enabling reduced overall data line count while maintaining adequate response time for each sub-pixel group.
Solution Approach 2:
The invention introduces a new dimension of control by separating data line connections based on gate line parity (odd/even). This dimensional reorganization allows the system to achieve both cost reduction through fewer data driving chips and performance maintenance through differentiated timing control for different data line groups.
2Manufacturing precision
If the turn-on time of each scan line is reduced to meet high resolution requirements, then display resolution is improved, but the response time becomes insufficient causing crosstalk effect
Solution Approach 1:
The invention implements dynamic control by applying different timing sequences to different data line groups. The first data lines (even columns) and second data lines (odd columns) receive data signals at different times, allowing the system to adaptively manage the trade-off between resolution and response time for different regions of the display.
Solution Approach 2:
The invention uses preliminary action by pre-charging or pre-positioning liquid crystal molecules in anticipation of the incoming data signal. This preliminary preparation allows the liquid crystal to respond faster when the actual switching signal arrives, effectively compensating for the reduced turn-on time required for high resolution displays.

AI summary
A liquid crystal display panel includes a sub-pixel array, a plurality of scan lines, and a plurality of data lines. The sub-pixel array has a plurality of sub-pixels arranged in array. Any two neighboring scan lines of the scan lines and a row of the sub-pixels disposed between the two neighboring scan liens are electrically connected. The sub-pixels arranged in odd rows are electrically connected to the odd-numbered data lines, and the sub-pixels arranged in even rows are electrically connected to the even-numbered data lines. Thus, the liquid crystal display panel is able to reduce mura phenomenon through the above-mentioned layout. A driving method of the above-mentioned liquid crystal display panel is also provided.
