Abstract

The invention provides a backlight module and a display device. The backlight module comprises a light source and a quantum conversion layer located on the light source, wherein the quantum conversionlayer is made of a mixture of a quantum dot material and a quantum rod material. By arranging the quantum conversion layer on the light source, the visual angle of the backlight module can be increased, so that the visual angle of the display device is increased, and the problems of narrow visual angle and serious color cast of the display device are well solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a display device. Background technique [0002] Liquid crystal display technology is widely used in many fields such as televisions, notebook computers, mobile phones, and monitors due to its advantages such as high display quality, light and thin body, low power consumption, large viewing area, and low cost. Among them, the VA display mode is widely used in liquid crystal displays due to its high contrast ratio and fast response time. However, because it uses liquid crystal rotation to control light, it causes problems such as narrow viewing angle and serious color shift. In large-scale liquid crystal display screens, the defect of its wide viewing angle is more obvious. Generally, the problem of viewing angle is solved by attaching a wide viewing angle film, but the cost of the wide viewing angle film is high, and after the film is pasted, the screen wi...
