Sideway-entering type quantum dot backlight module and display screen

Abstract

The invention discloses a sideway-entering type quantum dot backlight module which comprises a light guide plate, a support, a quantum pipe and at least one laser emitter. The support is in a strip shape and is arranged on one side of the light guide plate. A strip-shaped installation groove is formed in the length direction of the support. The shape of the installation groove is matched with that of the quantum pipe so that the quantum pipe can be contained. The opening of the installation groove faces the lateral side of the light guide plate so that light emitted by the quantum pipe can be emitted in from the lateral side of the light guide plate. The laser emitters are arranged on at least one end of the quantum pipe. The invention further discloses a display screen. The laser emitters serve as a light-entering source, emitted light is concentrated and high in penetrating power, the luminous flux in the quantum pipe is effectively increased, the backlight brightness of the quantum dot backlight module is easily improved, the laser emitters are arranged on the side face of the quantum pipe, and heat dissipation is facilitated.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a side-entry quantum dot backlight module and a display screen. Background technique [0002] With the development of display technology, the design of backlight becomes more and more diverse. Considering various factors such as picture quality, environmental protection and energy saving, the quantum dot backlight module came into being. The traditional quantum dot backlight module can refer to figure 1 As shown, a plurality of blue LEDs are installed on one side of the light guide plate 10, and quantum tubes 20 made of quantum dot materials are installed between the LEDs and the light guide plate 10. The blue LEDs excite the quantum dot materials on the quantum tubes 20 to form white light from a line source. , the white light from the line source passes through the light guide plate 10 to form a surface light source, and then passes through the optical film to form a quantum...

AI Technical Summary

Problems solved by technology

But due to figure 1 The side-entry backlight space shown is too small to place too many blue LEDs, resulting in low brightness of the side-entry quantum dot backlight module, which cannot further increase the brightness

If the blue LED is replaced with a high-power LED chip, the heat dissipation problem of the LED cannot be solved
