Integrated OLED-LCD Wearable Display Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wearable devices with two independent OLED and LCD display units suffer from non-uniform color distribution under the same lighting conditions, leading to one display being bright while the other is dim.
Innovation Solution
A single integrated display panel with both LCD and LED components, driven by a driver circuit that controls different frequencies and power levels for each portion, allowing for uniform illumination and improved readability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two independent display units (OLED and LCD) are used, then different display functions can be achieved, but uniform color distribution deteriorates and one display becomes bright while the other becomes dim
Solution Approach 1:
The patent merges two independent display units (OLED and LCD) into a single integrated display panel structure. The OLED layer and LCD layer are combined in one display unit, allowing them to work together as a unified system rather than separate independent displays, thereby achieving uniform color distribution while maintaining different display functions
Solution Approach 2:
The patent uses composite material structure by combining OLED (organic light-emitting diode) and LCD (liquid crystal display) technologies in a single display panel. This composite approach allows the display to leverage the strengths of both technologies - OLED's high brightness and LCD's color accuracy - while achieving uniform color distribution across the entire display area
2Adaptability or versatility
If two independent display units are used, then different display functions can be achieved, but device complexity increases
Solution Approach 1:
The patent merges two independent display units into a single integrated display panel, reducing the number of separate components. By combining OLED and LCD layers in one unified structure with shared control circuits, the patent simplifies the overall device architecture while maintaining the ability to perform different display functions through software control of different display regions
3Adaptability or versatility
If two independent display units are used, then different display functions can be achieved, but manufacturing precision requirements increase due to alignment issues
Solution Approach 1:
The patent merges OLED and LCD displays into a single integrated panel structure where both display technologies are fabricated together as one unit. This approach eliminates the need for precise alignment between separate display components, as the OLED and LCD layers are manufactured and integrated in a unified process, thereby reducing manufacturing precision requirements
Solution Approach 2:
The patent segments the single integrated display panel into different controllable regions (first display region and second display region) that can be independently controlled by the driver circuit. This segmentation allows different display functions to be achieved within the unified structure without requiring alignment between separate physical components
