Description

Technical Field

[0001] The utility model relates to a dimming film and a dimming glass, in particular to a dimming film and a dimming glass which can present hollow patterns. Background Art

[0002] Smart glass is a type of glass that is atomized when not powered on and transparent when powered on. The main principle is that after power is turned on, the light transmittance of the conductive layer inside the smart glass changes from low transmittance to high transmittance. The smart glass can be quickly switched between transparent (on) and atomized (off) by turning power on and off. Since it can block privacy in the off state and achieve a transparent effect in the on state, it is widely used in doors and windows, furniture, electrical appliances and other fields.

[0003] At present, the demand for dimming glass is becoming more and more diversified. In some application scenarios, dimming glass is not only required to block some privacy, but also to present a certain visual effect. The common operation method is to etch a separate pattern area on the conductive layer, connect the pattern area to the electrode and power supply separately, so that the pattern area and the non-pattern area can be turned on and off respectively. However, this operation scheme is relatively cumbersome to present the pattern, and the production cost is also high. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a dimming film and a dimming glass that can present a hollow pattern.

[0005] The purpose of the utility model is achieved by the following technical solutions:

[0006] A dimming film that can present a hollow pattern includes a first substrate layer, a first conductive layer, a liquid crystal mixing layer, a second conductive layer and a second substrate arranged in sequence, wherein the first conductive layer and the second conductive layer are respectively provided with hollow areas at the same positions, and the hollow areas form numbers or patterns.

[0007] Furthermore, hollow areas are respectively provided on the first substrate layer, the liquid crystal mixing layer and the second substrate, and the hollow areas on the first substrate layer, the liquid crystal mixing layer and the second substrate have the same position and shape as the hollow areas on the first conductive layer.

[0008] Furthermore, the edges of each of the hollow areas are smooth edges.

[0009] Furthermore, the first conductive layer and the second conductive layer are respectively provided with electrode lines.

[0010] Furthermore, the thickness of the first substrate layer and the second substrate layer is between 25um and 300um.

[0011] A dimming glass comprises a first light-transmitting plate, a second light-transmitting plate and a dimming film, wherein the dimming film is arranged between the first light-transmitting plate and the second light-transmitting plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] By opening a hollow area, in the non-powered state, the hollow area is transparent, and the non-hollow area is foggy. The non-hollow area can block part of the privacy, and the numbers or patterns formed in the hollow area can be presented; in the powered state, the dimming film and the dimming glass are transparent, hiding the numbers or patterns formed in the hollow area. The method of presenting numbers or patterns in the utility model is simpler, and a section of graphic information can be quickly hidden and switched. While taking into account both aesthetics and privacy protection, the production cost is lower. BRIEF DESCRIPTION OF THE DRAWINGS
