Display Screen Etched Anti-Glare Layer for Light Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display screens cause visual discomfort and are not conducive to eye protection, leading to potential eye damage due to issues such as glare and uneven light distribution.
Innovation Solution
The display screen incorporates an anti-glare layer formed by etching on the cover plate and/or the flexible screen, along with a light-homogenizing structure, to scatter and uniformize light emission, and may include an anti-reflection and transmission enhancement layer to reduce glare and improve light transmittance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional display screens are used, then the display function is achieved, but visual discomfort and eye damage occur due to glare and uneven light distribution
Solution Approach 1:
The patent applies an anti-glare layer with microlens array structure on the display screen surface. This layer converts harmful direct glare into beneficial diffuse light distribution. The microlenses refract and scatter the light from the light-emitting unit, transforming concentrated glare into uniform ambient illumination that protects eyes while maintaining display functionality
Solution Approach 2:
The patent changes the optical parameters of the display screen by introducing an anti-glare layer with specific microlens geometry (lens diameter, depth, spacing). This modifies the light emission characteristics from the light-emitting unit, transforming the light distribution pattern from concentrated and glary to diffuse and uniform, thereby reducing visual discomfort
2Illumination intensity
If the anti-glare layer is added to scatter light, then light uniformity improves, but light transmittance may be reduced
Solution Approach 1:
The anti-glare layer employs a microlens array structure with controlled spacing between lenses, creating an optically porous configuration. This allows light to pass through the gaps between microlenses while the lens surfaces provide the necessary scattering function. The porous-like structure enables simultaneous achievement of light diffusion and high transmittance
Solution Approach 2:
The patent uses spherical microlens elements in the anti-glare layer. The curved surfaces of these microlenses refract light in multiple directions, achieving uniform light distribution. The spherical geometry optimizes light scattering efficiency while maintaining high light transmission through the layer, as the curved surfaces guide light paths to emerge uniformly without excessive absorption or reflection losses
