The display unit layer 30 is connected with the inner layer glass 10 through a first adhesive layer or a second adhesive layer.
In this embodiment, the glass with display function 100 includes an edge area 101 and a display area 102, and the display unit layer 30 is located in the display area. Of course, the display unit layer 30 may occupy the entire used area of the glass. The inner layer glass 10, the first bonding layer 20, the second bonding layer 40 and the outer layer glass 50 may be of an approximately rectangular sheet structure (the shape is not limited thereto). The display unit layer 30 may be one or a combination of Light Emitting Diodes (LEDs), Organic Light Emitting Diodes (OLEDs), Liquid Crystal Displays (LCDs), projection display films, electroluminescence. Among them, the LED, LCD and OLED use an external electric field to make the internal light emitting material emit light, thereby achieving a display effect. The projection display utilizes the principle that the projection display film is specially used for achieving the display effect and has high reflectivity to the light of a projector. Electroluminescence utilizes an electric field to make electrons collide with a luminescence center to generate energy level transition, and finally luminescence is realized. These display technologies have fast response speed, low energy consumption and wide viewing angle. In this embodiment, a projection display film is taken as an example, and a projection light source is arranged to project information on the display area.

The outer layer glass 50 is a flat plate, or the outer layer glass 50 is curved glass. When the outer layer glass 50 is curved glass such as arc-shaped glass, the whole glass with practical functions can also be arc-shaped, such as front windshield glass of an automobile. The outer layer glass 50 comprises an outer side 51 and an inner side 52, and the display unit layer 30 is laminated on the inner side 52 of the outer layer glass 50 and is connected through the second bonding layer 40; the method specifically comprises the following steps: the second bonding layer 40 is bonded to the surface of the inner side 52 of the outer layer glass 50, and the display unit layer 30 is bonded to the side, opposite to the outer layer glass 50, of the second bonding layer 40. One side of the first adhesive layer 20 is adhered to the inner surface of the inner glass 10, and the other side of the first adhesive layer 20 is adhered to the surface of the display unit layer 30 facing away from the second adhesive layer 40. In this embodiment, the outer glass 50 is a gray glass, wherein the gray glass is generally produced by a transparent glass body-coloring techniqueAnd (4) completing. It is prepared by adding colorant based on the formula of common colorless transparent glass, controlling certain redox atmosphere to form uniform gray color, wherein the colorant comprises ferric oxide (Fe)2O3) Cobalt protoxide (CoO), nickel oxide (NiO), selenium (Se), and the like. The transmittance of natural light transmitted through the outer glass layer 50 may be 50% or less, for example, 18% or less, and preferably 10% or less, and the natural light transmittance may be set during the manufacturing process of the outer glass layer 50, and may be selectively matched during the use process. In this embodiment, the outer layer glass 50 is made of gray glass, and does not need to be conductive to adjust transmittance. The glass 100 with the display function effectively inhibits the interference of sunlight on the image displayed by the display unit layer 30 in the using process under the condition of the enhancement of external light, so that people in a vehicle can see clear images, and the image contrast is improved. Meanwhile, ultraviolet and heat radiation of sunlight to the interior of the vehicle can be reduced, the using amount of an air conditioner is reduced, and energy conservation and emission reduction are realized; and only grey glass is used, so that the cost is lower, and the product is lighter and thinner.
In an embodiment, the display unit layer 30 may also be disposed on the outer side of the inner glass 10, and when the display unit layer is used for a window of an automobile, the outer side is exposed in a natural environment, even if the display unit layer 30 is damaged, the display unit layer only needs to be taken down and attached again, and the later maintenance cost is saved.
In another embodiment of the present invention, in addition to the above-mentioned examples, the second adhesive layer 40 may be a low transmittance adhesive material, and the second adhesive layer is used for quantitatively controlling the natural light transmittance. The second adhesive layer 40 can be gray PVB film with natural light transmittance of 2-45%, light gray PVB film with natural light transmittance of 50%, blue PVB film with natural light transmittance of 2-8%, light blue PVB film with natural light transmittance of 31-37%, green PVB film with natural light transmittance of 21-36%, gray PVB film with natural light transmittance of 32-38%, or brown PVB film with natural light transmittance of 30-38%.

Specifically, the natural light transmittance of the second adhesive layer 40 made of gray polyvinyl butyral (PVB) is not more than 50%, and preferably, the natural light transmittance is not more than 8%; more preferably, the transmittance of natural light is 2% or less. The combination of the second bonding layer 40 and the outer glass 50 can effectively reduce the influence of external ambient light, enhance the contrast of the displayed image, and ensure that the product is thinner and lighter and has lower cost without adding a new layer structure of glass.

One or both of the outer ply of glass 50 and the inner ply of glass 10 may be laminated glass. The display unit layer 30 is disposed inside the inner glass 10 through the second adhesive layer 40. Of course, the display unit layer 30 can also be arranged on the outer side surface of the inner glass layer 10, and the second bonding layer 40 can be bonded, so that even if the display unit layer 30 is damaged, the display unit layer is only required to be taken down and attached again, and the later maintenance cost is greatly saved. In this embodiment, the second adhesive layer 40 may be used to quantitatively control the natural light transmittance. The second adhesive layer 40 is made of the natural light low transmittance material exemplified in the above embodiments.

The projection light source can be a fixed light source in a vehicle, and can also be a movable light source, such as a mobile phone. The display unit layer 30 of the glass with display function 100 is a projection display. And light beams emitted by the projection light source are incident to the display area where the display unit is positioned at a certain angle. The automobile can be unmanned or has an automatic driving function, and when the automobile needs a display unit to display a picture in an environment with stronger light, the outer layer glass 50 is gray, so that the light transmittance can be reduced, and the definition of the display picture is ensured. If the glass is also provided with a light modulation diaphragm 60, the light modulation function is started, and further picture display is ensured. For example, the glass is used on the windows of high-speed rails, when the display function is opened when the sunlight is strong during high-speed rail running, the display can still normally display without being influenced by ambient light, the glass can be used for screen projection, video watching, game entertainment, office work, advertisement putting, information prompting and the like by a mobile phone, and when the display function is closed, the glass does not influence passengers to watch scenery outside the windows. And later-period quick low-cost maintenance.
