Solution Overview
Problem
Light-diffusing particles in functional layers of display devices for enlarging chromaticity viewing angle exhibit poor dispersibility, leading to aggregation and reduced light transmission.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If light-diffusing particles are included in the functional layer for enlarging chromaticity viewing angle, then the chromaticity viewing angle is improved, but the particles tend to be poorly dispersed and aggregate
Solution Approach 1:
The patent changes the surface parameters of the whiskers by coating them with a polymer material that has compatible solubility characteristics with the resin composition. This parameter change in surface chemistry enables better dispersion of the light-diffusing particles throughout the functional layer, preventing aggregation while maintaining the chromaticity viewing angle enhancement effect.
Solution Approach 2:
The patent creates a composite structure by coating the whisker surface with a polymer layer, forming a core-shell composite material. This composite approach combines the light-diffusing properties of the whisker core with the improved interfacial compatibility of the polymer shell, achieving both good dispersion and effective light diffusion functionality.
2Adaptability or versatility
If the actual usage amount of light-diffusing particles is increased to compensate for poor dispersion, then the chromaticity viewing angle may be maintained, but the light transmission rate of the display device is reduced
Solution Approach 1:
By changing the surface parameters of the light-diffusing particles through polymer coating, the patent achieves uniform dispersion at lower concentrations. This eliminates the need to increase particle dosage, thereby maintaining high light transmission rates while still achieving the desired chromaticity viewing angle enhancement through efficient, evenly distributed light diffusion.
3Ease of manufacture
If unmodified whiskers are used in the resin composition, then the manufacturing process is simpler, but the dispersibility of the whiskers is poor leading to aggregation
Solution Approach 1:
The patent applies preliminary action by pre-coating the whisker surfaces with polymer material before incorporating them into the resin composition. This preliminary surface modification ensures that the whiskers are already dispersed-compatible with the resin matrix, preventing aggregation during mixing and application processes while maintaining manufacturing efficiency.

Implementation Method 1
the second polymer is attached to the whisker to obtain the polymer-modified whisker, and both the second polymer and the first polymer are a lipophilic polymer, thereby improving the dispersibility of the polymer-modified whisker in the resin composition
Implementation Method 2
a functional layer for enlarging chromaticity viewing angle is generally provided in a polarizer... light-diffusing particles included in the functional layer
