AI Technical Summary

Technical Problem

Display apparatuses suffer from undesirable characteristics such as pixel-to-pixel crosstalk and edge leakage, particularly in applications like LCDs, EPDs, and OLEDs.

Method used

A display apparatus design incorporating a substrate with light emitting diodes, a spacing member made of semiconductor, inorganic, or organic material, an optically clear adhesive, and a light scattering layer with dispersed light scattering particles, all of which are positioned to maintain spacing and enhance light scattering properties.

Benefits of technology

The solution improves light emission characteristics by reducing crosstalk and edge leakage, enhancing rigidity, and maintaining optical clarity while supporting high-temperature operations.

Abstract

A display apparatus (101) includes a substrate (103), a plurality of light emitting diodes (105) coupled to the substrate, and a spacing member (121) coupled to the substrate and positioned in a gap between a first light emitting diode (131) and a second light emitting diode (133). The spacing member (121) includes a semiconductor material, an inorganic material, or an organic material which can handle high temperature. The display apparatus includes an optically clear adhesive (107) over the plurality of light emitting diodes and the spacing member. The optically clear adhesive is spaced apart from the substrate by the spacing member. The display apparatus includes a light scattering layer (109) coupled to the optically clear adhesive. The display apparatus includes a glass layer (111) coupled to the light scattering layer. Methods of manufacturing a display apparatus are provided.
