Display Panel Sub-Pixel Segmentation for 3D Crosstalk Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D display devices suffer from crosstalk issues, which reduce image quality, and existing solutions either compromise the Low Color Washout function or significantly decrease vertical resolution when switching between 2D and 3D modes.
Innovation Solution
A display panel design where sub-pixels are configured to form shielding areas in 3D mode without turning off primary areas, maintaining image quality and resolution, by adjusting the optical transmission or brightness of specific sub-pixels to increase the separation distance between images.

Engineering Contradiction Analysis
1Object-affected harmful factors
If the primary area of sub-pixels is turned off to increase shielding area in 3D mode, then crosstalk is reduced, but the Low Color Washout function is disabled and color shifting problems occur
Solution Approach 1:
The sub-pixel is divided into two distinct functional areas: a primary area for color display and a secondary area for shielding. This segmentation allows the primary area to remain active and maintain the Low Color Washout function while the secondary area provides the necessary shielding to reduce crosstalk in 3D mode.
Solution Approach 2:
Different regions of the sub-pixel are assigned different functions with distinct optical properties. The primary area maintains full optical transmission for color display, while the secondary area has reduced transmission for shielding. This local differentiation enables simultaneous achievement of color accuracy and crosstalk reduction.
2Object-affected harmful factors
If every third row is turned off to increase shielding area in 3D mode, then crosstalk is reduced, but vertical resolution is reduced by 33%
Solution Approach 1:
Instead of turning off entire rows, the sub-pixels within each row are segmented into primary and secondary areas. This allows shielding functionality to be achieved at the sub-pixel level rather than the row level, preserving vertical resolution while still providing adequate shielding for crosstalk reduction.
Solution Approach 2:
The shielding function is moved from the row dimension (turning off entire rows) to the sub-pixel dimension (using secondary areas within sub-pixels). This dimensional shift allows shielding to be achieved without sacrificing vertical resolution.
3Object-affected harmful factors
If the shielding area is increased by turning off sub-pixels, then crosstalk is reduced, but the number of functional sub-pixels for image display is reduced
Solution Approach 1:
Each sub-pixel is segmented into a primary area for color display and a secondary area for shielding. This ensures that every sub-pixel contributes to image display through its primary area, while the secondary area provides shielding functionality, maximizing both image display capability and crosstalk reduction.
Solution Approach 2:
The sub-pixel structure is designed to perform multiple functions simultaneously: the primary area displays color information while the secondary area provides shielding. This multi-functionality ensures that shielding does not come at the expense of image display capability.

AI summary
Pixel structural designs on a display panel are disclosed. Each pixel on the display panel includes a plurality of sub-pixels. The sub-pixels are arranged sequentially along a vertical direction and used for displaying different colors in a circle. The display panel in the disclosure can be switched between a two-dimensional mode and a three-dimensional mode. In the three-dimensional mode, parts of the sub-pixels are disabled for forming a shielding area. Other adjacent sub-pixels form a pixel displaying unit.
