In order to achieve the effect of integrating the ink frame and the display area in vision when the screen is not lighted, if the ink frame and the display area are integrated into a whole, multiple tests and matching can be carried out on the ink, the touch screen and the liquid crystal screen. However, due to the offset relationship between the laminating layers, the light reflected by the glass cover plate has different brightness and darkness, and the integral sense of full-angle vision cannot be achieved.

In view of this, it is urgently needed to improve the existing glass cover plate so as to achieve the full-view visual integration effect of the ink frame and the display area when the screen is not lighted.

Detailed Description

To make the purpose, technical solution and advantages of the present invention clearer, the following will combine the embodiments of the present invention and the corresponding drawings to clearly and completely describe the technical solution of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

As shown in fig. 1 and fig. 2, the present invention provides an electrochromic glass cover plate, which includes a first glass layer 10, a first transparent conductive layer 20, an ion storage layer 30, an electrolyte layer 40, an electrochromic layer 50, a second transparent conductive layer 21, and a second glass layer 11, which are stacked. A groove is arranged on the electrochromic layer 50, and the second transparent conducting layer 21 is arranged in the groove; the size of the second glass layer 11 is larger than that of the groove; the thickness of the second transparent conductive layer 21 is equal to the height of the groove. The second glass layer 11 can cover the upper surface of the second transparent conductive layer 21. The electrochromic layer 50 and the second glass layer 11 can form a closed space for wrapping the second transparent conducting layer 21, because the upper and lower layers of the electrochromic layer 50 are transparent layers, the color of the electrochromic glass cover plate is the color of the electrochromic layer 50 when the electrochromic layer is not electrified, after the electrochromic layer is electrified, the middle part of the electrochromic layer 50 is reduced in an electric field to form a middle transparent visual area, and the periphery of the electrochromic layer 50 is not in the electric field, so that the electrochromic form is kept oxidized to form a colored frame. The screen keeps the integrative effect of full visual angle vision in display area when not bright, promotes user's experience and feels.

The first transparent conductive layer 20 is connected with the positive electrode; the second transparent conductive layer 21 is connected to the negative electrode.

The electrochromic layer 50 is colored when not energized. In this embodiment, a dark color is preferably used, such as: iridium dioxide and nickel oxide. Wherein the oxidation state of the iridium dioxide is bluish black, the reduction state is transparent, the oxidation state of the nickel oxide is dark brown, and the reduction state is transparent.

When the electrochromic layer 50 is powered on, the single-layer transmittance reaches 90%, and the transmittance after the electrochromic layer is correspondingly overlapped with the first transparent conductive layer 20 and the second transparent conductive layer 21 is 80% -83%. The whole transparency of the cover plate is high, and daily use of a user is met. Since the electric field reduces the oxide of the electrochromic layer 50 to form transparent regions after the application of electricity, the positions not corresponding to the first transparent conductive layer 20 and the second transparent conductive layer 21 are not in the electric field, and thus maintain the oxidized state, and a colored frame is formed.

It is preferable in this embodiment that the size of the first glass layer 10 is equal to the size of the electrochromic layer 50 corresponding to the first transparent conductive layer 20 and the second transparent conductive layer 21, since the region in the electric field after the electrochromic layer 50 is powered is transparent. The first glass layer 10 is thus sized to be the same as the transparent regions of the electrochromic layer 50, maximizing the display area.
