Embodiment Construction

[0100] figure 1 It is a schematic cross-sectional view of a transparent display device according to an embodiment of the present invention. Please refer to figure 1 , the transparent display device 100 is disposed on the transmission path of the background light beam X. The transparent display device 100 includes a backlight module 110 , a display panel 120 and a switching panel 130 . The backlight module 110 includes at least one light source 112 for emitting an illumination beam L and a light guide plate 114 . The light guide plate 114 has a light emitting surface 114a, a bottom surface 114b opposite to the light emitting surface 114a, and a light incident surface 114c connecting the light emitting surface 114a and the bottom surface 114b. The light source 112 is disposed beside the light incident surface 114 c of the light guide plate 114 . The illumination beam L enters the light guide plate 114 from the light incident surface 114c and leaves the light guide plate 114 ...

Abstract

The invention provides a transparent display device. The transparent display device comprises a backlight module, a display panel and a switching panel. The backlight module comprises a light source and a light guide board. The display panel is arranged on the light emergent surface of the light guide board. The switching panel and the backlight module are arranged on the same side of the display panel. The switching panel comprises a first substrate, a second substrate, a polymer dispersion liquid crystal layer, a first electrode layer and a second electrode layer, wherein the second substrate is opposite to the first substrate, the polymer dispersion liquid crystal layer is arranged between the first substrate and the second substrate, the first electrode layer is arranged between the first substrate and the polymer dispersion liquid crystal layer, and the second electrode layer is arranged between the polymer dispersion liquid crystal layer and the second substrate. The first substrate is divided into a plurality of first electrode patterns which are separated from one another and electrically independent of one another. In addition, the invention further provides another transparent display device.

Description

technical field [0001] The present invention relates to a display device, and in particular to a transparent display device. Background technique [0002] With the development of the display field, transparent display devices have been gradually developed. The transparent display device means that the transparent display device itself has a certain degree of penetration, so that the user can clearly see the background image behind the display panel. Transparent display devices can be applied to various applications such as building windows, automobile windows, shop windows, etc., and thus attract market attention. However, in the known technology, all the display areas of the transparent display device are used for transparent display, that is, all the display areas of the transparent display device display the background image and the display image of the display panel at the same time, and cannot switch to the display of the display panel. The non-transparent display mod...
