Light guide plate, backlight module, display device and driving method thereof

Abstract

The invention provides a light guide plate, a backlight module, a display device and a driving method thereof. The light guide plate has a light inlet surface and a light outlet surface which are relatively arranged. The light inlet surface of the light guide plate is used for facing a light emitting panel. The light guide plate is divided into a plurality of sub light guide plates. Each sub lightguide plate has a sub light surface and a sub light outlet surface. All sub light inlet surfaces form the light inlet surface. All sub light outlet surfaces form the light outlet surface together. The sub light outlet surface of the sub light guide plate is provided with an optical microstructure which is used for guiding the light which is incident from the sub light inlet surface of the sub light guide plate to the same direction. Furthermore the optical microstructure in at least two sub light guide plates is used for guiding the light which is incident from each light inlet surface to deflect in different directions. The light guide plate can realize double-vision displaying or multiple-vision displaying. Furthermore the light guide plate, the backlight module, the display device andthe driving method have advantages of simple structure, simple process and relatively high brightness.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a light guide plate, a backlight module including the light guide plate, a display device, and a driving method of the display device. Background technique [0002] The vehicle-mounted dual-view display technology enables drivers and passengers to see different images on the same screen. Refer to Chinese patent document CN04091523A, which uses a method of double barriers to realize double vision. However, this solution is difficult in process and high in cost, and the display brightness is reduced due to the shielding of the double gate barrier. Another example is the Chinese patent document CN03838034A which proposes a new backlight film structure to realize double viewing. This solution is also complex in structure, cannot avoid crosstalk problems, and cannot switch between dual-view and normal modes. There is no effective multi-view display technology in t...
