Embodiment 1

[0027] Such as Figure 2 to Figure 4 As shown, this embodiment provides a transparent display device, which includes a liquid crystal display panel 1 without a color film and a plurality of light emitting units 3 arranged outside the light-incident surface of the liquid crystal display panel 1 .

[0028] Among them, the liquid crystal display panel 1 includes two substrates facing each other, a liquid crystal layer is arranged between the two substrates, and polarizers are respectively arranged on the outside of the two substrates; at the same time, gate lines, data lines, thin film transistors, and pixels are also arranged on the substrates. Array structures used for displaying, such as electrodes, common electrodes, common electrode lines, alignment films, and black matrices, will not be described in detail here. However, the liquid crystal display panel 1 does not include a color filter, that is to say, it can only change the brightness of the light, but not the color of th...

Abstract

The invention provides a transparent display device and belongs to the technical field of transparent display. The transparent display device can solve the problem that an existing transparent display device is low in transmittance. The transparent display device comprises a liquid crystal display panel without a colorful film. The liquid crystal display panel comprises a plurality of pixel units used for display. The transparent display device further comprises a plurality of light-emitting units arranged outside a light incoming face of the liquid crystal display panel. Each light-emitting unit is used for emitting light of corresponding color to one pixel unit. The projection of one light-emitting unit on one pixel unit is smaller than the pixel unit.

Description

technical field [0001] The invention belongs to the technical field of transparent display, and in particular relates to a transparent display device. Background technique [0002] Transparent display technology refers to a display technology that can not only see the image displayed on the display panel, but also see the real scene behind the display panel. It is widely used in shop windows, booths, car windows, etc. [0003] Such as figure 1 As shown, in a transparent display device, the liquid crystal display panel 1 is used to filter the light from the direction of the real scene 9, so as to achieve the effect of transparent display; wherein, the liquid crystal display panel 1 usually includes two substrates for the box, A liquid crystal layer is arranged between the two substrates, and a polarizer is respectively arranged outside the two substrates. Since the liquid crystal display panel 1 itself does not emit light, it is easy to achieve transparency, and is especial...
