Abstract
Official abstract text for this publication.
The present disclosure relates to a backlight module and a display apparatus. The backlight module includes at least one light source; a light guide plate, including a bottom surface and a plurality of screen dot recessed parts arranged in a two-dimensional manner, where the screen dot recessed parts are located on the bottom surface, and each of the screen dot recessed parts is filled with a quantum dot material; and a substrate, disposed on the bottom surface of the light guide plate, and sealing the quantum dot material in the screen dot recessed parts of the light guide plate. The display apparatus includes a display panel and the backlight module.
First claim
Opening claim text (preview).
What is claimed is: 1 . A backlight module, comprising: at least one light source; a light guide plate, comprising a bottom surface and a plurality of screen dot recessed parts arranged in a two-dimensional manner, wherein the screen dot recessed parts are located on the bottom surface, and each of the screen dot recessed parts is filled with a quantum dot material; and a substrate, disposed on the bottom surface of the light guide plate, and sealing the quantum dot material in the screen dot recessed parts of the light guide plate. 2 . The backlight module according to claim 1 , wherein the substrate comprises a reflective surface. 3 . The backlight module according to claim 1 , wherein a refractive index coefficient of the substrate is less than or equal to a refractive index coefficient of the light guide plate. 4 . The backlight module according to claim 1 , wherein light excited by the light source has a wavelength in a range of 435 nanometers to 470 nanometers. 5 . The backlight module according to claim 1 , wherein the density of the screen dot recessed parts disposed decreases in a direction towards the light source and increases in a direction away from the light source. 6 . The backlight module according to claim 1 , wherein the quantum dot material has a yellow quantum dot material and a green quantum dot material. 7 . The backlight module according to claim 1 , wherein each of the screen dot recessed parts further comprises a separation glue, used for sealing the quantum dot material. 8 . A display apparatus, comprising: a display panel, configured to display an image; and a backlight module, comprising: at least one light source; a light guide plate, comprising a bottom surface and a plurality of screen dot recessed parts arranged in a two-dimensional manner, wherein the screen dot recessed parts are located on the bottom surface, and each of the screen dot recessed parts is filled with a quantum dot material; and a substrate, disposed on the bottom surface of the light guide plate, and sealing the quantum dot material in the screen dot recessed parts of the light guide plate. 9 . The display apparatus according to claim 8 , wherein the substrate comprises a reflective surface. 10 . The display apparatus according to claim 8 , wherein a refractive index coefficient of the substrate is less than or equal to a refractive index coefficient of the light guide plate. 11 . The display apparatus according to claim 8 , wherein light excited by the light source has a wavelength in a range of 435 nanometers to 470 nanometers. 12 . The display apparatus according to claim 8 , wherein the density of the screen dot recessed parts disposed decreases in a direction towards the light source and increases in a direction away from the light source. 13 . The display apparatus according to claim 8 , wherein the quantum dot material has a yellow quantum dot material and a green quantum dot material. 14 . The display apparatus according to claim 8 , wherein each of the screen dot recessed parts further comprises a separation glue, used for sealing the quantum dot material. 15 . A backlight module, comprising: at least one light source, exciting light having a wavelength in a range of 435 nanometers to 470 nanometers; a light guide plate, comprising a bottom surface and a plurality of screen dot recessed parts arranged in a two-dimensional manner, wherein the screen dot recessed parts are located on the bottom surface, each of the screen dot recessed parts is filled with a quantum dot material, and each quantum dot material has a yellow quantum dot material and a green quantum dot material; and a substrate, disposed on the bottom surface of the light guide plate, and sealing the quantum dot material in the screen dot recessed parts of the light guide plate, wherein a refractive index coefficient of the substrate is less than or equal to a refractive index coefficient of the light guide plate, wherein the density of the screen dot recessed parts disposed decreases in a direction towards the light source and increases in a direction away from the light source, wherein each of the screen dot recessed parts further comprises a separation glue, used for sealing the quantum dot material.
