Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies, particularly reflective and transflective type LCDs, suffer from low reflectivity due to refracted light caused by uneven surfaces, which affects imaging quality and energy consumption.
Innovation Solution
Incorporating a groove in the overcoating layer with a non-parallel configuration of the reflective layer's side and bottom surfaces, and optionally adding a light penetration enhancement layer or reflective micro-structure layer to enhance light reflection and transmittance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a reflective layer with an uneven surface is used to reduce manufacturing complexity, then the manufacturing process is simpler, but light reflection efficiency decreases due to refracted light
Solution Approach 1:
The reflective layer is segmented into multiple reflective sub-layers with different reflection rates, allowing each layer to contribute differently to the overall reflection efficiency while maintaining a relatively simple manufacturing process. The groove structure further segments the light path to enhance reflection.
Solution Approach 2:
Different regions of the reflective layer are given different properties through the groove structure and multiple sub-layers. The side surfaces of the groove have different reflection rates than the bottom surface, creating local quality variations that optimize light reflection while maintaining manufacturing simplicity.
2Use of energy by moving object
If the side surface of the groove and the side surface of the reflective layer are made non-parallel to enhance light reflection, then light reflection efficiency improves, but manufacturing precision requirements increase
Solution Approach 1:
The groove structure is designed with asymmetric angles where the side surface of the groove and the side surface of the reflective layer are intentionally made non-parallel. This asymmetric design optimizes light reflection efficiency while the patent provides specific angle ranges (110-130 degrees) to make manufacturing more controllable.
3Use of energy by moving object
If a light penetration enhancement layer is added to increase transmittance, then utilization rate of reflected light improves, but device complexity increases
Solution Approach 1:
A light penetration enhancement layer is introduced as an intermediary between the reflective layer and the overcoating layer. This intermediary layer enhances the transmittance of reflected light without requiring fundamental changes to the existing structure, thereby improving light utilization while adding only moderate complexity.
4Use of energy by moving object
If reflective type display is used to reduce power consumption, then energy consumption decreases, but imaging quality is affected by ambient light intensity
Solution Approach 1:
The display structure uses a composite reflective layer with multiple sub-layers having different reflection rates, combined with a groove structure and light penetration enhancement layer. This composite structure maintains the low power consumption advantage of reflective displays while improving imaging quality stability across different ambient light conditions through enhanced and more controlled light reflection.
