Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Polarization spectacles type stereoscopic displays have a narrow viewing angle due to the limited width of the black matrix, which increases the complexity and cost of control when using an active black matrix scheme, requiring twice the number of gate and data lines.
Innovation Solution
An array substrate with sub-pixel structures comprising a first and second sub-pixel, each with a pixel electrode and thin film transistor, connected via control lines to allow independent control, reducing control complexity and increasing the 3D viewing angle by effectively widening the black matrix.

Engineering Contradiction Analysis
1Length of moving object
If an active black matrix scheme is used to increase the 3D viewing angle, then the viewing angle is improved, but the control complexity and cost increase due to requiring twice the number of gate and data lines
Solution Approach 1:
The pixel electrode is divided into a first sub-pixel electrode and a second sub-pixel electrode, which are controlled by different gate lines. This segmentation allows the black matrix width to be effectively increased for improved 3D viewing angle while maintaining the original number of gate lines, thus resolving the contradiction between viewing angle improvement and control complexity increase.
2Length of moving object
If the black matrix width is increased to improve 3D viewing angle, then the viewing angle is improved, but the pixel area is reduced
Solution Approach 1:
By segmenting the pixel electrode into two sub-pixel electrodes and using different gate lines to control them, the effective black matrix width is increased without sacrificing pixel area. The segmentation allows for optimized light blocking in the vertical direction while maintaining horizontal pixel dimensions.
Solution Approach 2:
The solution addresses the viewing angle problem by operating in the vertical dimension through gate line control rather than increasing horizontal black matrix width. This dimensional approach allows viewing angle improvement without reducing pixel area.
3Length of moving object
If the black matrix width is increased to improve 3D viewing angle, then the viewing angle is improved, but the resolution is reduced
Solution Approach 1:
The pixel electrode segmentation into first and second sub-pixels, controlled by different gate lines, effectively increases the black matrix width for improved viewing angle while maintaining the original pixel density and resolution through electrical control rather than physical expansion.
