Solid-State Total Reflection Display Light Adjusting Structures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Solid-state total reflection displays are affected by ambient light, leading to degraded display effects due to the lack of a shield structure between pixels, which causes interference and reduces contrast.
Innovation Solution
A solid-state total reflection display is designed with a drive circuit layer, a heating layer, and a pixel function layer, including light adjusting structures with a concave shape to redirect and absorb ambient light, preventing it from entering the pixel structures and enhancing contrast.

Engineering Contradiction Analysis
1Length of stationary object
If no shield structure is arranged among individual pixels to reduce thickness, then the display thickness is reduced, but ambient light is reflected by metal lines causing interference and degraded display effect
Solution Approach 1:
A light adjusting structure is introduced as an intermediary element between adjacent pixel structures. This structure includes a light adjusting layer with light adjusting particles that selectively adjust ambient light, preventing harmful light reflection from metal lines while maintaining display thinness. The light adjusting particles act as mediators that interact with ambient light to reduce interference without requiring traditional shield structures.
Solution Approach 2:
The light adjusting structure is locally positioned between adjacent pixel structures rather than implementing a comprehensive shield across the entire display. The light adjusting particles are distributed in specific regions where ambient light interference occurs most significantly, providing targeted light adjustment while maintaining overall display transparency and thinness.
2Object-affected harmful factors
If a shield structure is added to block ambient light interference, then the display effect is improved, but the thickness of the display increases
Solution Approach 1:
The light adjusting structure utilizes a thin light adjusting layer containing light adjusting particles, which functions as a flexible optical control layer rather than a rigid shield structure. This thin film approach provides effective ambient light management while maintaining the display's thin profile, avoiding the thickness increase associated with traditional shield structures.
Solution Approach 2:
The light adjusting particles serve as intermediaries that selectively interact with ambient light wavelengths, adjusting harmful light before it reaches the metal lines and drive circuit layer. This intermediary approach blocks interference light without requiring physical shields, thereby preventing thickness increase.
3Device complexity
If metal lines in the drive circuit layer reflect ambient light, then the display structure is simplified, but light interference occurs degrading display contrast
Solution Approach 1:
The light adjusting structure is positioned between the ambient light source and the metal lines in the drive circuit layer, acting as an intermediary that pre-adjusts the ambient light. The light adjusting particles selectively absorb or scatter harmful light wavelengths before they can be reflected by the metal lines, preventing contrast degradation while maintaining structural simplicity.
Solution Approach 2:
The light adjusting structure performs preliminary anti-action by adjusting ambient light before it reaches the metal lines that would cause harmful reflection. By pre-processing the ambient light in the light adjusting layer, the system prevents the formation of harmful reflected light, thereby protecting display contrast without adding complex shielding structures.
