Display Panel Pixel Blocks for Independent Viewing Angle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses lack the ability to independently control the viewing angle and adjust the ratio of regions based on user requirements, necessitating a method for freely adjusting the viewing angle control.
Innovation Solution
A display panel with a plurality of pixel blocks and mode control line sets, including first and second mode control lines, allows for independent control of viewing angles by selectively driving first and second light emitting devices with different lens regions, enabling flexible adjustment of viewing angle regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display apparatus uses a single viewing angle mode for the entire display area, then the device complexity is reduced, but the adaptability to different user requirements and content types is limited
Solution Approach 1:
The display area is divided into multiple independent pixel blocks, where each pixel block can be controlled to have different viewing angle characteristics. This segmentation allows different regions to display content with appropriate viewing angles (wide for shared content, narrow for private content) without requiring a completely complex system redesign, as each block operates independently with similar internal structures
Solution Approach 2:
The patent implements dynamic switching between wide viewing angle mode and narrow viewing angle mode for each pixel block. By using mode control lines to dynamically adjust the viewing angle characteristics of different pixel blocks based on content requirements and user preferences, the system achieves high adaptability while maintaining a relatively simple static structure that can be reconfigured through control signals
2Measurement precision
If the display area is divided into multiple pixel blocks with independent viewing angle control, then the viewing angle control precision is improved, but the device complexity increases due to additional control lines and circuits
Solution Approach 1:
The mode control lines are designed to serve multiple functions: they can control the viewing angle mode of individual pixel blocks, work in combination with scan lines to activate specific pixel blocks, and integrate with the existing display control architecture. This multi-functionality reduces the need for separate dedicated control circuits for each pixel block, thereby limiting the increase in overall device complexity while maintaining precise control capability
3Ease of operation
If multiple mode control line sets are used to control different pixel blocks, then the ease of operation for adjusting viewing angles is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent merges the mode control functionality with the existing scan line structure of the display. Mode control lines are integrated into the regular grid of scan lines and data lines, allowing them to be manufactured using the same photolithography and wiring processes as the rest of the display. This merging approach enables easy operation through software-controlled signal patterns while avoiding the need for separate manufacturing processes that would increase complexity and cost
