AI Technical Summary
When the existing dimming glass etches the segmentation line of the conductive layer, it is necessary to open the conductive layer in the edge position or add it to the edge channel, resulting in limited pattern selection and the pattern cannot be freely displayed and hidden.
Using a dimming film including a first substrate, a first conductive layer, a liquid crystal mixed layer, a second conductive layer and a second substrate, it is divided into a plurality of regions by etching the segmentation line on the conductive layer, and these regions are embedded. Set in another area to ensure that the electrical conductivity is not conducted, thereby setting electrodes at any position to achieve the presentation and hiding of the graphics and text patterns.
It realizes the composition of the original pattern without destroying it, enriches the pattern selection, and makes it easier to switch the pattern to show and hide the pattern.

Abstract
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 capable of presenting graphic 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, and the smart glass can be quickly switched between transparent (on state) and atomized (off state) by turning power on and off. In order to enable the smart glass to block some privacy while presenting a certain visual effect, the usual operation method is to etch a dividing line on the conductive layer, and the conductive layer is divided into a first area and a second area through the dividing line. The first area and the second area are respectively connected to electrodes, so that the first area and the second area are respectively turned on or off.
[0003] This operation mode has the following disadvantages: in order to allow the first region to be connected to the electrode independently, the first region needs to be opened at the edge of the conductive layer or added to the side channel, which results in very limited choices of the pattern of the first region. 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 graphic patterns.
[0005] The purpose of the utility model is achieved by the following technical solutions:
[0006] A dimming film capable of presenting graphic patterns comprises a first substrate, a first conductive layer, a liquid crystal mixed layer, a second conductive layer and a second substrate arranged in sequence, wherein the first conductive layer and / or the second conductive layer are respectively etched with a dividing line, wherein the dividing line divides the first conductive layer and / or the second conductive layer into a first area and a second area, wherein the first area is embedded in the second area, and there is no conductivity between the first area and the second area.
[0007] Furthermore, the first region includes at least two sub-regions, each of the sub-regions is non-conductive with the second region, and edges of each of the sub-regions form the same or different numbers or patterns.
[0008] Furthermore, the width of the dividing line is 0.1 μm-1 mm.
[0009] Furthermore, the second region of the first conductive layer and the second region of the second conductive layer are respectively provided with electrodes.
[0010] Furthermore, an antistatic coating is provided on a side of the first substrate away from the first conductive layer and / or on a side of the second substrate away from the second conductive layer.
[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] The first area of the utility model does not need to be deliberately placed on the edge or added to the side channel, and can be opened at any position of the first conductive layer or the second conductive layer, without destroying the composition of the original pattern, and the pattern selection is more abundant. Compared with traditional dimming films and dimming glasses, this product can show and hide patterns at will, and the switching is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
