Liquid Crystal Display Pixel Array Inclination Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid crystal display devices face inefficiencies in designing pixel arrays with inclination angles, leading to increased work time and decreased work efficiency due to design limitations on grid patterns and data processing units.
Innovation Solution
A liquid crystal display device configuration where pixels are arranged in a matrix form with varying pitches and angles, specifically with first and second pixels having equal pitches in one direction and different pitches in another, and third and fourth pixels having specific rational angle relationships, allowing for efficient inclination of pixel arrays by angles such as 28 to 32 degrees.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pixels are arranged with an inclination angle to prevent disclination and moire, then image quality is improved, but design complexity and work time increase due to grid pattern limitations
Solution Approach 1:
The patent applies parameter changes by using rational number relationships for pixel array pitches (e.g., Px/Py = m/n where m and n are integers) and setting inclination angles based on rational trigonometric values (sinθ, cosθ, tanθ as rational numbers). This allows the pixel array to be inclined while maintaining compatibility with standard grid patterns, thus improving image quality by preventing disclination and moire without significantly increasing design complexity or work time.
2Reliability
If pixels are arranged with an inclination angle to prevent moire, then image quality is improved, but device complexity increases due to non-uniform pitch arrangements
Solution Approach 1:
The patent resolves the contradiction by changing parameters to rational number relationships. By defining pixel pitches Px and Py with integer ratios (m/n) and setting inclination angles where sinθ, cosθ, and tanθ are all rational numbers, the patent achieves inclined pixel arrangements that prevent moire while maintaining regular, manufacturable patterns that do not significantly increase device complexity.
3Adaptability or versatility
If different pitch arrangements are used for first and second pixels, then inclination capability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent addresses manufacturing precision concerns by using rational number relationships for pitch ratios (Px/Py = m/n where m and n are integers). This ensures that even though different pitch arrangements are used for first and second pixels to achieve inclination, the ratios remain simple and manufacturable, avoiding overly complex precision requirements while maintaining good inclination capability.
