Embodiment Construction

[0019] Existing double-sided display devices only have a single-sided or double-sided display function, and do not have a transparent display function.

[0020] In view of this, the present invention provides a double-sided display device, comprising:

[0021] Two PDLC displays opposite to each other; wherein, each of the PDLC displays includes: a TFT array substrate with pixel electrodes, a common electrode substrate opposite to the TFT array substrate, and a substrate located between the TFT array substrate and the TFT array substrate. A PDLC layer between the common electrode substrates, switchable transparent state and scattering state;

[0022] A toner located between two TFT array substrates; wherein, the toner includes: two transparent electrode layers opposite to each other, and a transparent state and a black state can be switched between the two transparent electrode layers color layer.

[0023] The present invention utilizes the characteristic that the PDLC displa...

Abstract

The invention relates to the technical field of liquid crystal display and in particular to a double-sided display device. The double-sided display device is used for realizing single-sided display, double-sided display or transparent display. The invention discloses the double-sided display device which comprises two PDLC (Polymer Dispersed Liquid Crystal) displays arranged back to back, wherein each PDLC display comprises a TFT (Thin Film Transistor) array substrate with a pixel electrode, a common electrode substrate opposite to the TFT array substrate and a PDLC layer positioned between the TFT array substrate and the common substrate as well as a toning device positioned between the two TFT array substrates; and the toning device comprises two transparent electrode layers opposite in position and a toning layer which is positioned between the two transparent electrode layers and can be switched between a transparent state and a black state. By using the characteristic that the toning device can be switched between the transparent state and the black state and the characteristic that the PDLC display can be switched between the transparent state and a scattering state, the double-sided display device has functions of single-sided display and double-sided display and a transparent display function.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a double-sided display device. Background technique [0002] With the continuous development of liquid crystal display technology, information display panels used in airport waiting halls, railway station waiting halls or large exhibition halls, or in business halls of communication industry, government window, financial industry, transportation industry and other window industries The display panel generally adopts a double-sided display device, so that the user can obtain the required information. Existing double-sided display devices generally include: two single-sided displays facing each other are pasted together, and each liquid crystal display corresponds to a driving circuit independently, so that the double-sided display device can realize single-sided or double-sided screen display . For example, the double-sided display in the prior art includes a firs...
