Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] Due to the high color gamut of the quantum dot material, applying the quantum dot material to the backlight module and providing light to the liquid crystal display panel through the quantum dot material can improve the display color gamut of the liquid crystal display. The related art provides two kinds of backlight modules using quantum dot materials. In a side-entry backlight module integrated with quantum dot materials, the glass tube encapsulated with quantum dot materials is arranged between the light bar and the light guide plate, and the light emitted by the light bar excites the quantum dot materials to emit light, and the quantum dots The light emitted by the material enters the liquid crystal display panel after being...

Abstract

The invention discloses a light guide plate as well as a manufacturing method, a backlight module and a display device thereof and belongs to the field of display technology. The light guide plate comprises a light guide plate body and a quantum dot film layer arranged on a light emergent surface of the light guide plate body, wherein the quantum dot film layer is prepared from a transparent material mixed with a quantum dot material in a nano imprinting way. The light guide plate disclosed by the invention encapsulates the quantum dot material by virtue of the transparent material, and the selected transparent material has relatively high tightness on the quantum dot material, thereby avoiding failure of the quantum dot material after being contacted with water and oxygen and improving encapsulation reliability on the quantum dot material.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light guide plate and a manufacturing method thereof, a backlight module and a display device. Background technique [0002] A liquid crystal display (Liquid Crystal Display, LCD) includes a liquid crystal display panel and a backlight (Backlight) module arranged on the back of the liquid crystal display panel. The backlight module is usually divided into a side-type backlight module and a direct-type backlight module. The traditional side-type backlight module includes a light bar and a light guide plate. The light bar is arranged on the side of the light guide plate. The light emitted by the light bar enters the liquid crystal display panel after being transmitted by the light guide plate to provide light for the liquid crystal display panel. Due to the high color gamut of the quantum dot material, applying the quantum dot material to the backlight module and providing light...
