Abstract

The invention provides a transparent display device including a display panel and a backlight module. The display panel is arranged on the backlight module. The backlight module includes a light guide board and a light source module. The light guide board includes a body and a light incoming part. The body is provided with a light emitting face and a light receiving side, wherein the light receiving side is on the edge of a side of the light emitting face. The light receiving part is connected with the light incoming side of the body. The light source module is arranged corresponding to the light incoming part. Light beams produced by the light source module enter into the body through the light incoming part. The light beams have a comparatively contracting light beam type after entering into the light receiving part than before entering into the light receiving part. Possibilities of light leakage in a transparent area can be reduced. Transparent degree of the transparent zone is increased. And backlight zone production can be controlled.

Description

technical field [0001] The present invention relates to a display device and its backlight module; specifically, the present invention relates to a partially see-through display device and its backlight module. Background technique [0002] In recent years, flat panel display devices have been widely used in various fields, and can be used as displays alone or embedded in electronic devices for information display. There are various types of flat panel display devices, such as organic light emitting diode displays, liquid crystal displays, electrophoretic displays, etc., among which liquid crystal displays are currently the most common flat panel display devices. [0003] As far as the traditional liquid crystal display device is concerned, it only simply provides image display, but cannot see through the display device to see behind the scene. However, in the recent development direction, in order to meet the needs of specific applications, see-through display devices have...
