Problems solved by technology

[0005] However, the existing transparent displays represented by the above-mentioned patent documents have the disadvantage of low contrast, which is much lower than ordinary displays.
The reason is that since the transparent display has a certain degree of light penetration, the background on the back side of the transparent display will interfere w

Example Embodiment

[0030] As the best embodiment of the present invention, please refer to FIG. 1, the transparent display provided by the embodiment of the present invention includes a normally white mode TFT-LCD (Thin Film Transistor Liquid Crystal Display) layer 1 and a quantum conversion layer 2, PDLC (Polymer Dispersed) Liquid Crystal) or PNLC (Polymer Network LiquidCrystal) layer 3, light guide plate layer 4, liquid crystal light changing layer 5.

[0031] As shown in the figure, the design of the TFT-LCD layer 1 is a combined array substrate structure including front and rear polarizers, and has two states of imaging and transparency. The composite array substrate structure in the figure refers to the 1, 9, 10 three-layer composite structure, and the whole is called an array substrate. Among them, 9 is the front polarizer structure, which plays a polarizing role. 10 Rear polarizer, analyzing polarization. The substrate is a transparent glass substrate or a plastic substrate. In addition...

Abstract

The invention discloses a transparent display, and relates to the technical field of electro-optic display. The transparent display comprises a TFT-LCD layer, a quantum conversion layer, a PDLC or PNLC layer, a light guide plate layer and a liquid crystal changing light layer which are arranged in sequence in a stacked mode, the TFT-LCD layer is a combined array substrate structure which contains a front polaroid and a rear polaroid; the quantum conversion layer is used for transforming an optical wavelength which is transmitted by light into light with another wavelength, which correspondingly illuminates an image under a TFT-LCD imaging pattern; the PDLC or PNLC layer is used for making penetrated light show a scattering state or a transparent state; the light guide plate layer is used for making LED strong light scatter and illuminate the image in the TFT-LCD layer; the liquid crystal changing light layer is of a layered shape structure which becomes mirror glass when electrified or becomes transparent glass when not electrified. Through the adoption of the transparent display, the contrast and the transmittance of the display are improved while the energy consumption is low and the service life is longer, compared with an ordinary scheme which relies on reflective light, the display effect is more excellent, the permeability is better, under the existing process technology, implementation is easier, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of photoelectric display, in particular to a transparent display. Background technique [0002] With the development of display technology, liquid crystal display devices are widely used in a wide range of fields from small information terminals to transmissive large-scale projection equipment. More and more manufacturers have successively introduced transparent displays with see-through function. With transparent displays, the information displayed on the display can be seen when voltage is applied, and the information on the back of the display can be seen through the display when no voltage is applied. object. In addition to the original display function, the transparent display device can also have future display features such as providing information. Therefore, it has attracted market attention and may replace some markets that use displays in the future. It is expected that a large number of existing...
