Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing stereoscopic display devices suffer from reduced resolution due to the inefficient use of pixels, where some pixels are dedicated to displaying images for the left eye while others are for the right eye, leading to a loss in overall display quality.
Innovation Solution
A display driving method and device that alternately arranges first and second pixel units with sub-pixels of different colors in a matrix, using a grating with light shading and transmitting regions to calculate and determine the display brightness of each sub-pixel based on color components, effectively increasing the display brightness output area and avoiding resolution loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all pixels are dedicated to displaying images for left eye or right eye separately, then the stereoscopic display function is achieved, but the resolution is reduced
Solution Approach 1:
The patent combines the display of left eye and right eye images by arranging first pixel units (for left eye) and second pixel units (for right eye) in an alternating matrix pattern. This merging approach allows both stereoscopic function and full pixel utilization, resolving the contradiction between achieving stereoscopic display and maintaining resolution.
Solution Approach 2:
The patent introduces a grating structure with light shading regions and light transmitting regions that directs light from adjacent pixel units to different eyes. This adds a spatial dimension (light direction control) to the display system, enabling full pixel utilization while maintaining stereoscopic separation.
2Reliability
If a grating with light shading regions is used to direct light to different eyes, then the stereoscopic effect is improved, but the display brightness output area is reduced
Solution Approach 1:
The grating is designed with local differentiation: light shading regions are positioned to shade only specific areas (first region of first pixel unit and second region of second pixel unit) while light transmitting regions allow light from other areas to pass through. This local quality approach maintains stereoscopic effect while maximizing the effective display brightness output area.

Function Achieved in This Case
The method enhances the resolution of stereoscopic displays by optimizing the use of sub-pixels, allowing for a higher display effect with improved brightness distribution and reduced resolution loss, enabling a more effective stereoscopic display experience.
Implementation Method 1
The grating includes a plurality of light shading regions and a plurality of light transmitting regions provided alternately both in the row direction and the column direction, each of the light shading regions being configured for shading a first region of the first pixel unit and a second region of the second pixel unit opposite to the first region of the first pixel unit which are adjacent in the row direction
