Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display panels experience slow response times due to differences in electric field forces between the pixel electrode and the light-shielding electrode, particularly in the middle region of the pixel electrode, leading to chaotic liquid crystal alignment and slow response.
Innovation Solution
The liquid crystal display panel incorporates a pixel electrode with a middle region and a peripheral region, where the liquid crystals in the middle region have a greater pretilt angle than those in the peripheral region, achieved through the use of wider first branch electrodes in the middle region and narrower second branch electrodes in the peripheral region, with a specific ratio of their areas to enhance electric field force and stabilize liquid crystals faster.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the pixel electrode and light-shielding electrode are used with uniform branch electrode widths, then the manufacturing process is simple, but the liquid crystals in the middle region of the pixel electrode experience weak electric field force causing slow response
Solution Approach 1:
The patent applies local quality by dividing the pixel electrode into different regions (middle region and peripheral region) with different branch electrode widths. The middle region has wider branch electrodes to generate stronger electric field force for faster liquid crystal response, while the peripheral region has narrower branch electrodes. This non-uniform design optimizes the electric field distribution to address the slow response problem in the middle region without compromising manufacturing feasibility.
2Speed
If wider branch electrodes are used in the middle region to improve response time, then the liquid crystal response speed improves, but the device structure becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the pixel electrode into distinct regions (middle region and peripheral region) with different branch electrode configurations. The middle region contains wider branch electrodes for enhanced electric field force and faster response, while the peripheral region has narrower branch electrodes. This segmented approach allows optimization of different regions for their specific functions while maintaining overall structural organization and manufacturability.
