Embodiment Construction

[0047] The invention provides a three-dimensional display device and a backlight module used therein. In a preferred embodiment, the three-dimensional display device is a liquid crystal panel display device, and can be used as a flat-screen TV, a display of a personal computer, a display of a notebook computer or a display of other electronic devices to provide stereoscopic visual effects.

[0048] Such as figure 2 As shown, the three-dimensional display device includes a display panel 100 and a backlight module 300 . In a preferred embodiment, the display panel 100 is, for example, a liquid crystal display panel, including transmissive, transflective or other types. The display panel 100 is disposed above the backlight module 300 to receive the light provided by the backlight module 300 , and the display panel 100 controls the incident light to form a displayed image. In addition, in this embodiment, the rhombic sheet 200 is further included between the backlight module 30...

Abstract

A three-dimensional display apparatus and a backlight module thereof are provided. The display apparatus further includes a display panel disposed on the backlight module. The backlight module has a light guide plate, a plurality of microstructures, a first light source, and a second light source. The light guide plate has a bottom surface and a light emitting surface opposite to the bottom surface, wherein the microstructures are disposed on at least one of the two surfaces. The first light source is at a first corner of the light guide plate while the second light source is at a second corner opposite to the first corner. A first surface and a second surface of the microstructure define an orientation direction (or form a distribution direction) along or parallel to the diagonal line through the first and second corners.

Description

【Technical field】 [0001] The present invention relates to a three-dimensional display device and its backlight module; specifically, the present invention relates to a three-dimensional display device and its backlight module. The three-dimensional display device has the function of displaying stereoscopic images in multiple directions. 【Background technique】 [0002] As the market's demand for stereoscopic visual effects gradually grows, the applications of stereoscopic 3D display devices in various fields are increasing, such as televisions, desktop monitors, notebook computers, mobile handheld devices, cameras, and so on. Three-dimensional display technology uses the parallax of human eyes to synthesize different images, making people feel three-dimensional. Traditionally, display devices for generating stereoscopic visual effects are mainly divided into two types: using special glasses and not using special glasses. In terms of 3D image display technology that does not ...
