Display Substrate With Segmented Pixel Units for Contrast Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies with transparent display functions suffer from low display contrast due to the transmission of backlight through the display substrate, which affects the screen display quality.
Innovation Solution
A display substrate with pixel units featuring a first region with a single-sided light-emitting unit and a second region containing color-variable components that can switch between transparent and non-transparent statuses, allowing for controlled light emission and absorption to enhance contrast and display effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a transparent display function is implemented, then the display panel can achieve transparent display effect, but the display contrast deteriorates due to backlight transmission
Solution Approach 1:
The pixel unit is divided into two distinct regions: a first region containing a single-sided light-emitting unit for light emission, and a second region containing color-variable components for light modulation. This segmentation allows each region to perform its specific function independently, achieving both transparent display effect and improved contrast.
Solution Approach 2:
The color-variable components in the second region are configured to dynamically switch between transparent and non-transparent states based on display requirements. When the light-emitting unit is active, the color-variable components transition to a non-transparent state to enhance contrast; when inactive, they return to transparent state to maintain the transparent display effect.
2Illumination intensity
If color-variable components are added to control light transmission, then display contrast improves, but the device complexity increases
Solution Approach 1:
The color-variable components are integrated directly into the second region of the pixel unit structure, merging the light modulation function with the existing display architecture. This combination approach avoids adding separate complex control systems while achieving contrast enhancement.
Solution Approach 2:
The color-variable components are selectively placed only in the second region of the pixel unit, where they are needed for contrast enhancement, rather than throughout the entire display panel. This localized approach minimizes the overall device complexity while achieving the desired contrast improvement in specific areas.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution improves display contrast and effectiveness by controlling the color-variable components to either absorb or transmit light based on the display status, thereby enhancing the overall display experience.
Implementation Method 1
each of the at least one color-variable component is switchable between a transparent status and a non-transparent status
Implementation Method 2
the first region includes a first light-emitting unit which is a single-sided light-emitting unit
