Display Subpixel Circuit for Dynamic Area Ratio Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a display apparatus that can freely adjust the ratio of multiple display areas in response to user requests or display images, particularly for large-scale electronic devices like automobiles.
Innovation Solution
The display apparatus includes a display panel with a configuration of subpixels, each comprising a driving transistor, an emission control transistor, and light emitting elements, along with mode control transistors that allow the display area to be driven in different modes, enabling the adjustment of the ratio of first and second display areas by controlling the emission of light in specific areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display apparatus is designed with a fixed display area configuration, then the manufacturing process is simple, but the display area ratio cannot be adjusted according to user requests or display images
Solution Approach 1:
The display area is segmented into multiple independent display areas (first display area and second display area), each controlled by separate light emitting elements and mode control transistors. This segmentation enables independent control of each display area's emission state, allowing flexible adjustment of display area ratios without affecting the overall display structure
Solution Approach 2:
The display apparatus transitions from a static display area configuration to a dynamic one where the display area ratio can be changed in real-time. Mode control transistors dynamically switch between different emission modes (first mode and second mode), enabling the display to adapt to different user requests and display image requirements
2Adaptability or versatility
If mode control transistors are added to enable display area ratio adjustment, then adaptability is improved, but the number of transistors per subpixel increases
Solution Approach 1:
The mode control transistors serve multiple functions: they control the switching between different light emitting elements, manage the emission timing of each display area, and enable the display apparatus to operate in different modes. This multi-functionality reduces the need for separate control circuits for each function, thereby limiting the increase in transistor count
