Display Panel Layout for ClearType Font Deformation Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies suffer from font deformation and unsatisfactory display effects when using ClearType, particularly due to the conventional tri-gate drive architecture, which increases manufacturing costs and power consumption.
Innovation Solution
A display panel design with a scan driving circuit on the long side and a drive circuit board on the short side, utilizing a chip on film to connect the drive circuit board to the display substrate, and arranging RGB sub-pixels in sequence along the long side to improve font display clarity.

Engineering Contradiction Analysis
1Ease of manufacture
If the tri-gate drive architecture is used to reduce the number of source driver chips, then manufacturing cost is reduced, but font deformation occurs and display effect deteriorates
Solution Approach 1:
The invention divides the drive circuit functionality into two separate components: a scan driving circuit integrated on the array substrate and a drive circuit board separate from the substrate. This segmentation allows the scan driving circuit to control gate lines while the drive circuit board handles data lines, eliminating the font deformation issues associated with integrated tri-gate architecture while maintaining cost efficiency through reduced chip usage.
Solution Approach 2:
The invention introduces a chip-on-film component as an intermediary element that connects the drive circuit board to the display substrate. This intermediary enables flexible signal transmission and electrical connection between the separate drive circuit board and substrate, allowing the system to achieve both cost reduction and improved font display accuracy by decoupling the drive functions.
2Reliability
If the scan driving circuit is located on the short side and drive circuit board on the long side, then ClearType compatibility is improved, but device complexity increases
Solution Approach 1:
The invention employs asymmetric placement of drive circuit components relative to the display substrate, with the scan driving circuit positioned on the short side and the drive circuit board on the long side. This asymmetric configuration optimizes signal transmission paths for ClearType font rendering while managing circuit complexity through strategic spatial distribution of functional elements.
