Display Device Fading Pattern for Light Shielding Boundary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with light shielding layers suffer from obvious boundaries due to color contrast when switched off, and manufacturing damage can lead to visible differences between original and new shielding layers, affecting the visual effect.
Innovation Solution
A display device with fading patterns adjacent to the light shielding layer, comprising multiple light transmissible areas with varying transmittances that gradually change color from the shielding layer to the display area, eliminating the obvious boundary and potential differences between new and original shielding layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a light shielding layer is formed on the periphery of the display area, then light leakage is prevented and components are hidden, but an obvious boundary appears between the light shielding layer and display area when switched off
Solution Approach 1:
The fading pattern introduces local quality variation by creating multiple light transmissible areas with different transmittances within the peripheral region. Each area has a specific transmittance value that gradually changes from the light shielding layer to the display area, making the boundary less obvious while maintaining light shielding functionality.
Solution Approach 2:
The invention changes the optical parameter (transmittance) of the peripheral pattern by dividing it into multiple areas with different transmittance values. This parameter variation creates a gradient effect that reduces the visual contrast at the boundary between the light shielding layer and display area.
2Ease of manufacture
If the display device is cut and ground during manufacture, then processing is completed, but the outside of the light shielding layer may be damaged to peel easily
Solution Approach 1:
The fading pattern with multiple light transmissible areas serves as a cushioning structure that prevents peeling before it occurs. The gradual transmittance transition creates a buffer zone that absorbs stress and prevents the light shielding layer from peeling during cutting and grinding operations.
3Reliability
If a new light shielding layer is added to the outside of the original light shielding layer, then damage is covered, but an obvious boundary appears due to color difference between new and original layers
Solution Approach 1:
The fading pattern creates local quality differences in the peripheral region, where each light transmissible area has a specific transmittance. This local variation in optical properties helps to mask the boundary between new and original light shielding layers by providing a gradual transition zone.
Solution Approach 2:
By introducing multiple light transmissible areas with different transmittance parameters, the invention creates a gradient effect that reduces the visual contrast at the boundary between new and original light shielding layers, making the repair less noticeable.
