Abstract

An embodiment of the invention provides a backlight module and a display device and relates to the technical field of display with an aim to realize repeat adjustment of LED lamps during regional dimming. The backlight module comprises a light source assembly and a light-rendering film arranged on the light emerging side of the light source assembly; the light-rendering film comprises a plurality of dimming unit arrayed in matrix form; the dimming units are used for receiving dimming signals and changing transmittance of the dimming units according to the diming signals. The backlight module is used for providing backlight.

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] In recent years, the development of HDR (High-Dynamic Range, High Dynamic Light Rendering) technology has once again set off a wave of application of Local Dimming technology on display devices. The regional dimming technology can make the displayed image have more dynamic range of light and dark and image details, so as to present users with images of higher quality. However, in the prior art, in order to realize the above-mentioned regional dimming technology, it is usually necessary to adjust the LED lights in the backlight individually. In this way, it is easy to cause damage to the LED lamp in the process of repeated adjustment, reducing the service life of the backlight source. Contents of the invention [0003] Embodiments of the present invention provide a backlight module and a display device, wh...
