DETAILED DESCRIPTION

[0031] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0032] Example 1

[0033] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0034] Please refer to Figure 1 As shown, an embodiment of the utility model provides a hidden display screen, which includes: an LCM module layer 1, a double-sided laminate layer 2 and a hidden cover layer 5 which are sequentially bonded together; the hidden cover layer 5 is provided with an environmentally-simulated light-transmitting material, and its light transmittance is 17-19%.

[0035] In the above embodiment, the hidden display screen has a hidden cover layer 5 and an environment-simulating light-transmitting material to solve the problem of the single function and the inharmonious visual experience of the existing display screen. Specifically, the hidden display screen provides the needs of camouflage and hiding. By adding a hidden cover layer and an environment-simulating light-transmitting material, the display screen can be integrated with the surrounding environment when not in use, presenting a camouflage effect, thereby avoiding the limitation of a single function; wherein, the hidden cover layer uses an environment-simulating light-transmitting material with a transmittance of 17-19%, and the material can make the hidden display screen consistent with the visual characteristics such as brightness and color of the surrounding environment when the display screen is closed, reducing the inharmonious visual experience; when the display screen is turned on, the image can be displayed normally. Through the design of the hidden cover layer and the environment-simulating light-transmitting material, the hidden display screen can be integrated with the surrounding environment when not in use, providing a better camouflage effect, so that the display screen is not easily detected. For example, in decoration, it can be hidden in the wall, and when not in use, it is used as part of the wall. When the device is turned on, the image is displayed after the display screen receives the signal. The simulated ambient light-transmitting material on the hidden cover layer can adjust the light transmittance of the display screen so that the display screen is consistent with the surrounding environment when it is closed, reducing the visual disharmony. The hidden display screen not only has the functions of an ordinary display screen, but can also provide camouflage and hiding effects when needed, increasing the flexibility and diversity of its application.

[0036] Example 2

[0037] The utility model embodiment provides a hidden display screen, referring to Figures 3 to 6 As shown, the hidden cover layer 5 includes: an ambient light-transmitting material layer 53, a second optical adhesive layer 52 and a transparent cover layer 51; the ambient light-transmitting material layer 53 is bonded and connected to the LCM module layer 1 through the double-sided bonding layer 2; the ambient light-transmitting material layer 53 is one of integrated gray, integrated silver brushed, integrated white, integrated carbon fiber, integrated mahogany wood grain color and integrated tile color.

[0038] By using one of the above-mentioned integrated gray, integrated silver brushed, integrated white, integrated carbon fiber, integrated mahogany wood grain color and integrated tile color as the ambient light-transmitting material layer 53, the above-mentioned hidden display screen can more flexibly select materials close to the environment, so that the above-mentioned hidden display screen can have better flexibility.

[0039] In one embodiment of the present application, Figure 2 As shown, it also includes a functional sheet layer 3 and a first optical adhesive layer 4; one side of the functional sheet layer 3 is bonded and connected to the LCM module layer 1 through the double-sided bonding layer 2, and the other side is bonded and connected to the hidden cover layer 5 through the first optical adhesive layer 4; the two sides of the functional sheet layer 3 are electrically connected to the driving circuit board 6. The above-mentioned LCM module layer 1 can be a TFT-LCD screen, wherein the above-mentioned LCM (Liquid Crystal Module) is the abbreviation of liquid crystal module, which is an integral component containing a liquid crystal display and related driving circuits. The above-mentioned functional sheet layer 3 is used to provide a touch operation function for the display screen, so that the above-mentioned hidden display screen supports touch operation.

[0040] It should be noted that the liquid crystal module itself does not have a touch operation function. In the prior art, the touch screen is realized by adding a touch sensor module on the basis of the liquid crystal module; the touch sensor module is usually directly pasted on the surface of the liquid crystal module, or connected to the liquid crystal module at a certain distance. On the touch sensor module, there will be a layer of transparent conductive material (such as ITO) to transmit touch signals. When the user touches the screen, the conductive material on the touch screen (such as the human body) will cause disturbances in the electric field around the conductive material, which will be captured by the sensor and converted into digital signals, and finally output to the electronic device for processing through the controller.

[0041] In one embodiment of the present application, Figure 4 and Figure 7 As shown, the driving circuit board 6 is an FPC board, which includes an FPC cable 62 and a circuit area 61 that are set as one body; wherein, the back of the circuit area 61 is at least partially covered with a steel sheet for reinforcement. The FPC board and the related electronic components are soldered on it to form the above-mentioned driving circuit board, and the above-mentioned FPC cable 62 and the circuit area 61 are an integrated FPC, which can reduce the thickness and is conducive to the ultra-thinness of the hidden display screen, and at least the chip position in the circuit area 61 is reinforced with a steel sheet, and the steel sheet reinforcement can also cover the back of the entire circuit area 61, so that it can increase the strength of its FPC.

[0042] In addition, heat dissipation can also be achieved through steel sheet reinforcement. Windows can be opened at the grounding position to make the steel sheet reinforcement grounding connection. At the same time, the heat dissipation is directed to the steel sheet reinforcement position through the metal ground wire (generally the grounding is the copper-clad area), thereby dissipating heat through it and enhancing its heat dissipation effect.

[0043] Example 3

[0044] The utility model provides a hidden display screen, wherein a protective film 7 is attached to the surface of the hidden cover layer 5 to protect the transparent cover layer 51 of the hidden cover layer 5, wherein the transparent cover layer 51 has a thickness of 1.1 mm and is made of glass material; Figure 7 As shown, a positive protection handle 71 is provided at one corner of the protective film. For example, the film can prevent dust or other things from dirtying the surface of the display screen. Especially during decoration or installation, dust or sweat on the hands can be easily printed on it, and it can also prevent scratches to a certain extent. When it is necessary to remove the protective film, it can be directly torn off through the positive protection handle 71.

[0045] In one embodiment of the present application, the double-sided adhesive layer 2 preferably uses 3M4930 double-sided adhesive. The above 3M4930 is a foam-based double-sided adhesive among 3M double-sided adhesives. 3M 4930 has strong bonding force, can firmly bond a variety of surface materials, can maintain good adhesion performance in high temperature environments, can withstand temperatures up to 149°C, and has excellent weather resistance and chemical resistance, is not easily affected by moisture, water and some chemical solvents, can provide excellent shear strength, can withstand large shear stress, and is easy to peel off during pasting.
