Abstract

The invention relates to the field of display technologies, and discloses a light guide device, a backlight module group and a display device, wherein the light guide device comprises a light guide plate made from a transparent material, and at least one pair of electrodes; a plurality of lattice points are arranged in the light guide plate; each lattice point comprises a cavity chamber, and white cataphoresis particles; the cavity chamber is formed in the light guide plate; the white cataphoresis particles are arranged in the cavity chamber; the electrodes are used for forming electric field in lattice points when in electrification; the electric field is parallel to the light-emitting surface of the light guide plate. When the light guide device is out of a working state, the lattice point structure on the light guide plate cannot be seen; the transparent effect is good; the transparent displaying effect of the displaying device can be improved by utilizing the light guide device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light guide device, a backlight module and a display device. Background technique [0002] The transparent display device displays images on the display screen when it is in the working state, and the objects on the back of the display screen can be seen through the display screen when it is not in the working state. Generally, LCDs or OLEDs with high transmittance are used to prepare transparent displays. [0003] The display device provides light source through the backlight module. When the traditional transparent display device is not working, that is, when the backlight is not used, the dots on the light guide plate in the backlight module can be seen, so the transparent effect is not good. Contents of the invention [0004] The invention provides a light guide device, a backlight module and a display device, wherein, when the light guide device is in a non-working stat...
