Switchable AMOLED Reflective Display Panel for Eye Strain Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices with smaller sizes, such as smartphones and tablets, cause eye fatigue and physical discomfort due to improper reading, especially in outdoor conditions, and existing dual-mode displays require complex operation to switch between reflective and color modes, risking damage.
Innovation Solution
A display panel integrating a top emission AMOLED display sub-panel and a normally-white mode reflective display sub-panel with a switching element, allowing seamless switching between the two modes on the same interface without the need for a backlight, reducing eye strain and simplifying operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dual-mode display products with separate reflective and color screens are used, then both reflective display and color display functions are achieved, but the device becomes complex in operation and easily damaged when switching between modes
Solution Approach 1:
The patent combines the reflective display sub-panel and color display sub-panel into a single integrated display device with a unified operation interface. The switching element is controlled through the same touch screen interface, eliminating the need for separate screens and reducing operational complexity while maintaining both display mode functions.
Solution Approach 2:
The unified operation interface serves multiple functions: it acts as the display interface for both reflective and color modes, and as the control interface for switching between modes. This multi-functional design simplifies the overall device structure and reduces the number of separate components needed.
2Ease of manufacture
If traditional AMOLED display is used, then color display function is achieved, but eye fatigue and physical discomfort occur during prolonged use, especially in outdoor conditions
Solution Approach 1:
The display dynamically switches between color display mode and reflective display mode based on ambient lighting conditions and user needs. The switching element can be controlled to select the appropriate display mode, providing eye protection in outdoor conditions by using the reflective mode which reflects ambient light rather than emitting light.
3Object-affected harmful factors
If reflective display sub-panel is placed on the display surface, then eye protection is achieved, but the display structure becomes complex and occupies more space
Solution Approach 1:
The reflective display sub-panel and color display sub-panel are merged into a single integrated display structure sharing common components including the switching element, control circuitry, and operation interface. This integration reduces the overall device complexity and space occupation compared to having separate reflective and color display devices.
