Problems solved by technology

[0004] In other words, one of the main factors affecting the color gamut rendering capability of the display is the choice of backlight. With a backlight with a high color gamut, the colors presented by the display will be richer, closer to the color of the object itself and the color Bright, low-color-gamut backlights will deviate the color displayed by the display, and cannot fully represent the actual color of the object

Abstract

The invention discloses an optical film, a light-emitting apparatus containing same and a display. The optical film includes a first base material, a second susbtrate, and a scattering layer. The scattering layer contains a plurality of quantum dots and a plurality of scattering particles. Each quantum dot is excited after receiving a first color light and transmits a second color light having a wavelength greater than that of the first color light. The light-emitting apparatus includes the optical film and a light-emitting module. The light-emiting moduel is disposed on one side of the first base material and can transmit the first color light which enters the scattering layer and excites the quantum dot to transmit the second color light. Each color light is subject to light mixing and is transmitted by the second base material. The display includes the light-emitting apparatus and a panel. The panel is arranged on one side of the light-emitting apparatus, and presents image with the aid of the light effects generated by light transmitted by the light-emitting appartus. The optical film increases the light path radiated by the first color light on the scattering layer by means of the scattering particles so as to excite more quantum dots and achieve a wide color gamut.

Description

technical field [0001] The invention relates to an optical film and a light-emitting device and a display containing the optical film, in particular to an optical film capable of improving color gamut, and a light-emitting device and a display containing the optical film and having a wide color gamut. Background technique [0002] One of the existing light emitting diode (LED) light-emitting devices to generate white light is to use quantum dots (quantum dots) as the light-emitting layer of the light-emitting diode, and the quantum dots of different materials or particle sizes are irradiated by the excitation light source , which is obtained by mixing light after emitting secondary light with a wavelength different from that of the excitation light source. For example, blue light is mostly used as the excitation light source, and quantum dot materials with different particle sizes are excited to generate red light and green light, and then the red light, green light, and blu...
