Display Panel Wide View Angle Adjustment via Pixel Gray Scale
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The adjustment cost of the wide view angle for display panels is relatively high due to the need for additional circuits and wires, which reduces the aperture ratio and increases the area of backlight strips.
Innovation Solution
A method that adjusts the gray scale values of two pixels located in the same column and adjacent rows to achieve a target difference value, allowing for wide view angle adjustment without additional circuits or wires, by reducing or increasing the gray scale values based on a determined target difference value, ensuring the total brightness remains constant.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional circuits and wires are added to adjust wide view angle, then the wide view angle adjustment capability is improved, but the aperture ratio decreases and the backlight area increases
Solution Approach 1:
The patent changes the parameter of gray scale values of pixels to achieve wide view angle adjustment. Instead of adding physical circuits, the system adjusts the display parameters (gray scale values) of existing pixels to create the desired brightness distribution pattern, thereby improving adaptability without increasing hardware complexity or reducing aperture ratio
Solution Approach 2:
The patent replaces the mechanical/electrical system of additional circuits and wires with a software-based parameter adjustment system. By substituting physical hardware modifications with parameter changes in the display signal processing, the system achieves the same functional goal without the adverse effects of increased component area
2Adaptability or versatility
If additional circuits and wires are added to adjust wide view angle, then the wide view angle adjustment capability is improved, but the adjustment cost increases
Solution Approach 1:
The patent extracts the wide view angle adjustment function from the physical hardware domain and relocates it to the signal processing domain. By removing the dependency on additional circuits and wires, the system eliminates the associated manufacturing complexity and cost while preserving the adjustment capability
Solution Approach 2:
The patent creates a virtual representation of the adjustment function through parameter modification rather than physical duplication of hardware components. The gray scale value adjustment serves as a software copy of the hardware adjustment mechanism, achieving the same effect with significantly lower cost
