Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-glare coatings with large or unevenly distributed diffusion particles result in uneven surface haze and refraction capabilities, leading to reduced anti-glare effects and 'flashing points' in display devices, particularly when applied to high-resolution displays.
Innovation Solution
A surface finishing method involving a resin material with spherical diffusion particles of controlled density, where the thickness of the resin layer is greater than the particle size, ensuring even dispersion and exposure of particles, thereby maintaining consistent surface haze without increasing particle sizes or stacking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the particle sizes of diffusion particles are enlarged to enhance anti-glare effect, then surface haze increases, but particle distribution becomes uneven and flashing points occur
Solution Approach 1:
The patent changes the density parameter of the resin material to be less than the density of diffusion particles, which fundamentally alters the distribution mechanism from random suspension to controlled sinking, achieving both large particle size and uniform distribution
Solution Approach 2:
The patent creates a composite material system combining resin material and diffusion particles with specific density relationships, where the composite structure enables uniform distribution of large particles through density-driven positioning during curing
2Illumination intensity
If diffusion particles of various particle sizes are used to enhance anti-glare effect, then surface haze increases, but particle distribution becomes uneven
Solution Approach 1:
The patent changes the density parameter of the resin material to be less than the density of diffusion particles, which fundamentally alters the distribution mechanism from random suspension to controlled sinking, achieving both large particle size and uniform distribution
Solution Approach 2:
The patent applies preliminary action by establishing the density relationship between resin and particles before curing, causing particles to automatically position themselves uniformly during the curing process rather than requiring post-processing
3Manufacturing precision
If the thickness of resin layer is increased to embed diffusion particles, then particle distribution improves, but production efficiency decreases
Solution Approach 1:
The patent applies self-service by utilizing the natural density difference between resin and particles to achieve automatic uniform distribution during curing, eliminating the need for complex multi-layer stacking processes and improving production efficiency

AI summary
A surface finishing method, an anti-glare coating, and a display device having same are provided. The surface finishing method includes adding diffusion particles which have a density less than that of a resin material, and controlling the thickness of the resin material in an anti-glare material coated on a surface of a substrate to be greater than the particle size of the diffusion particles, so that the diffusion particles are evenly dispersed in the resin layer, and a part of the volume of the diffusion particles are exposed on a surface of the resin layer. Thus, the uniformity of the surface haze of the anti-glare coating can be enhanced, and flashing points of the display device can be avoided.
