Pixel Matrix Peep-Proof Sub-Pixel Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display apparatuses with peep-proof functions face challenges in achieving effective peep-proof effects while minimizing the use of optical films, which are expensive and increase the thickness of the display module, leading to reduced display quality and wide viewing angle luminance.
Innovation Solution
A display apparatus with a pixel matrix comprising 12 sub-pixels arranged in a matrix, including first, second, and third color sub-pixels, and a sub-pixel rendering unit using wide and narrow viewing angle gamma lookup tables to adjust performance values for sub-pixels, allowing for peep-proof display without additional optical films.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If optical films (light control film, prism film, diffuser) are added to achieve peep-proof function, then peep-proof capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts the peep-proof function from the optical film layer and relocates it to the pixel arrangement structure. By arranging sub-pixels in specific patterns (e.g., alternating color patterns like RGBRGB or RRBBGG in 2x2 blocks) and controlling their emission characteristics, the peep-proof effect is achieved directly from the pixel matrix without requiring additional optical films.
Solution Approach 2:
The patent replaces the mechanical/optical film-based peep-proof solution with an electronic/pixel-control-based solution. Instead of using physical optical films to block or redirect light, the system uses electronic control of individual sub-pixel emission to create directional light distribution and achieve peep-proof effects through software-driven pixel rendering.
2Reliability
If optical films are added to achieve peep-proof function, then peep-proof capability is improved, but display quality and wide viewing angle luminance deteriorate
Solution Approach 1:
The patent applies different emission characteristics to different sub-pixels within the same pixel unit. By assigning specific colors and emission intensities to individual sub-pixels based on their position and the desired viewing angle, the system achieves directional light control (peep-proof) while maintaining high luminance in the intended viewing direction. Each sub-pixel is optimized for its specific role in the overall display performance.
3Reliability
If optical films are added to achieve peep-proof function, then peep-proof capability is improved, but manufacturing cost increases
Solution Approach 1:
The patent uses software-based pixel rendering to create virtual optical effects that replace physical optical films. By copying and adapting the peep-proof function from optical film behavior into software control algorithms that manipulate pixel emission patterns, the system achieves the same functional effect without the cost of expensive optical film materials and their associated lamination and alignment processes.
4Reliability
If optical films are added to achieve peep-proof function, then peep-proof capability is improved, but display module thickness increases
Solution Approach 1:
The patent extracts the peep-proof function from the optical film layer and relocates it to the pixel arrangement structure. By arranging sub-pixels in specific patterns (e.g., alternating color patterns like RGBRGB or RRBBGG in 2x2 blocks) and controlling their emission characteristics, the peep-proof effect is achieved directly from the pixel matrix without requiring additional optical films.
