Technical Field

The present invention relates to the field of transparent display, and in particular, to a transparent display panel and a transparent display device.

Background

In the field of Display technology, flat panel Display devices such as Liquid Crystal Display (LCD) devices and Organic Light Emitting Diode (OLED) Display devices have gradually replaced CRT (Cathode Ray Tube) Display devices. The liquid crystal display device has many advantages of thin body, power saving, no radiation, etc., and is widely used.

In recent years, with the vigorous development of display technology, transparent display devices have been increasingly emphasized. Generally, a transparent display device can provide a user with a display image, and the user can see through the transparent display device to view a display object or scene behind the transparent display device. That is to say, the transparent display device has the original display function and also has the characteristic of displaying the background behind the picture, and can be widely applied to the display windows of large-scale commercial exhibition, shop windows or commodity display cabinets, so as to achieve the purpose of displaying advertisement images and displaying commodities at the same time, and greatly enrich the visual perception of users.

The transparent display screen enables audiences to see screen images and see objects behind the screen through the screen, enhances the efficiency of information transmission, increases much interest, brings unprecedented visual experience and brand new experience for users, and is widely applied to various fields.

It is to be noted that the information invented in the above background section is only for enhancing the understanding of the background of the present invention, and therefore, may include information that does not constitute prior art known to those of ordinary skill in the art.

Disclosure of Invention

In order to solve the above problems, the present invention provides a transparent display panel and a transparent display device to solve the technical problem of the prior art that contrast and display effect are reduced due to pursuit of a high transparency display panel.

The technical scheme for solving the problems is as follows: the invention provides a transparent display panel, which comprises a first array substrate; the first liquid crystal layer is arranged on the first array substrate; the second array substrate is arranged on one side, far away from the first array substrate, of the first liquid crystal layer; the second liquid crystal layer is arranged on one side, far away from the first liquid crystal layer, of the second array substrate; and the transparent substrate is arranged on one side of the second liquid crystal layer, which is far away from the second array substrate.

Further, the first liquid crystal layer and the second liquid crystal layer are scattering liquid crystal layers.

Furthermore, the thickness range of the first liquid crystal layer and the second liquid crystal layer is 3 um-50 um.

Further, the transparent cover plate is a glass substrate.

Further, a first circuit pattern is arranged on the first array substrate and used for driving the first liquid crystal layer; and a second circuit pattern is arranged on the second array substrate and used for driving the second liquid crystal layer.

Further, the first circuit pattern and the first circuit pattern are identical and aligned with each other.

Further, the first liquid crystal layer and the second liquid crystal layer have the same thickness.

Further, the material of the first liquid crystal layer and the second liquid crystal layer includes at least one of polymer scattering liquid crystal and polymer network liquid crystal.

Furthermore, the contrast ratio of the transparent display panel is 100: 1-1600: 1.

The invention also provides a transparent display device which comprises the transparent display panel.

The invention has the advantages that: according to the transparent display panel and the transparent display device, the transparent display panel comprises the first array substrate and the second array substrate, circuit patterns of which are accurately aligned, and the liquid crystal layers arranged on the first array substrate and the second array substrate, the contrast of the transparent display panel is improved through double-layer liquid crystal display, meanwhile, the loss of the light transmittance of the transparent display panel is avoided due to the accurate alignment of the circuit patterns of the first array substrate and the second array substrate, and the liquid crystal layer adopts scattering liquid crystals, so that pictures displayed by the transparent display panel are softer, and the display quality of the transparent display panel is improved.
