Solution Overview
Problem
The hexagonal pixel configuration in organic EL displays poses challenges in forming well-deposited organic layers, making it difficult to achieve effective multi-grayscale display due to its complex structure.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hexagonal pixel configuration is used in organic EL displays, then multi-grayscale display capability is improved, but the organic layer deposition quality deteriorates due to complex structure
Solution Approach 1:
The pixel is divided into multiple sub-pixels (first, second, and third display regions) that can be independently controlled. This segmentation allows the organic layer to be deposited in a simpler, more uniform manner across each sub-region while still achieving multi-grayscale display through selective activation of different sub-pixels.
Solution Approach 2:
The patent implements dynamic pixel configuration where the pixel unit can change between different states (first state with first and second regions, second state with second and third regions). This dynamic reconfiguration enables multi-grayscale display without requiring a fixed complex hexagonal structure, thereby improving organic layer deposition quality.
2Adaptability or versatility
If a hexagonal pixel configuration is used, then display versatility is improved, but device complexity increases making manufacturing difficult
Solution Approach 1:
The pixel configuration is made dynamic rather than static. The same physical pixel structure can be configured in different states (first state using first and second display regions, second state using second and third display regions), providing display versatility without requiring physically complex hexagonal arrangements.
Solution Approach 2:
The display device achieves multiple functions (different grayscale levels, different display modes) using a universal pixel structure composed of first, second, and third display regions. This universal structure can be configured differently to achieve various display objectives, eliminating the need for specialized complex structures for each function.
3Measurement precision
If multiple display regions are used for gray scale expression, then grayscale precision is improved, but control complexity increases
Solution Approach 1:
The pixel is segmented into multiple independent display regions (first, second, and third regions) that can be individually controlled. This segmentation enables precise grayscale control by selectively activating different combinations of regions, while each region's independence simplifies the control logic compared to controlling a single complex structure.

AI summary
The present invention provides a display device which can display characters clearly and display images smoothly. An area gray scale method is adopted and a configuration of one pixel is changed depending on a mode, by selecting one or more display regions in each pixel. When characters are needed to be displayed clearly, one pixel is configured by selecting a stripe arrangement. Thus, clear display can be conducted. When images are needed to be displayed, one pixel is configured by selecting an indented state. Thus, smooth display can be conducted.
