Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Reflective and trans-reflective displays have low power consumption but suffer from limited brightness due to insufficient reflectance, necessitating improvements in reflective efficiency.
Innovation Solution

Engineering Contradiction Analysis
1Illumination intensity
If a single reflective layer is used in reflective display, then the device structure remains simple, but the reflectance and display brightness are insufficient
Solution Approach 1:
The reflective layer is segmented into multiple reflective sub-layers (first reflective layer and second reflective layer) with different reflective characteristics. The first reflective layer provides base reflectance while the second reflective layer enhances reflectance in specific regions, collectively achieving high display brightness without excessive structural complexity.
Solution Approach 2:
Different regions of the reflective structure are assigned different reflective properties. The second reflective layer is positioned to cover specific areas (such as pixel electrode regions) to provide enhanced local reflectance, while the first reflective layer provides uniform base reflectance across the entire display area, optimizing overall brightness distribution.
2Illumination intensity
If multiple reflective layers are added to enhance reflectance, then display brightness improves, but device complexity increases
Solution Approach 1:
The reflective system is divided into functional segments: a first reflective layer for base reflectance and a second reflective layer with reflective sub-layers for enhanced reflectance in specific regions. This segmentation allows each layer to perform its specific function efficiently, achieving high overall reflectance without requiring excessive layers.
Solution Approach 2:
The second reflective layer with its plurality of reflective sub-layers provides enhanced reflectance action in specific regions where additional brightness is needed, while the first reflective layer handles the base reflectance requirements. This partial application of enhanced reflectance where needed optimizes overall display brightness without uniformly increasing complexity across the entire device.

Function Achieved in This Case
The enhanced reflective design improves display brightness and efficiency by maximizing the reflective area coverage with high reflectance materials, achieving desirable reflective and trans-reflective display effects.
Implementation Method 1
The first reflective layer is disposed on the first insulating layer. The second reflective layer is disposed on the second insulating layer. The second reflective layer includes a plurality of reflective sub-layers, and a portion of the first reflective layer is disposed corresponding to a gap between two adjacent ones of the plurality of reflective sub-layers.
