AI Technical Summary
Technical Problem
Insufficient color gamut performance of LCD displays affects the color reproduction capability and visual experience of images.
Method used
A narrowband filter is added to the display device, and the light from the light-emitting device is filtered by using the Fabry-Perot resonant cavity structure to narrow the half-width of the forward emitted light, thereby improving the color purity and color gamut of the light.
Benefits of technology
It improves the color gamut and half-viewing angle brightness of the display device, enhances in-plane uniformity, reduces light absorption loss, and improves environmental stability.

Abstract
The application discloses a display device to improve the color gamut of the display device. The display device includes a light-emitting substrate and one or more narrow-band filters. The light-emitting substrate includes a substrate and a plurality of light-emitting devices. The plurality of light-emitting devices are located on the substrate. One narrow-band filter is located on the light-emitting side of a corresponding light-emitting device. One narrow-band filter includes a first Bragg reflection layer, a second Bragg reflection layer, and a spacer layer located between the first Bragg reflection layer and the second Bragg reflection layer and including a resonant cavity, and the first Bragg reflection layer is located on the side of the spacer layer close to the light-emitting device.
