[0032] In related display technology, a display panel capable of being hidden under the skin of a terminal is usually applied on a smart terminal, which usually includes a display layer and a texture layer. The display layer is used to display the content required to be displayed by the user. The texture layer is placed on the side of the display layer presenting the display picture, which is provided with a texture pattern that can be integrated with the environment, so as to hide the display layer through the texture pattern when the display layer does not need to display, so as to achieve the effect of integration of the skin of the smart terminal, and make the existence of the display panel more natural. However, this display panel is essentially equivalent to a semi-transparent material printed with a texture pattern, when the display layer below is lighted, the texture layer above will block the picture displayed by the display layer, thereby affecting the display effect, and may cause misjudgment operation, etc., reducing the use experience of customers.

[0033] In order to solve the problems existing in the above display technology, the display device provided in the embodiments of the present application can be a smart terminal with display function such as a smart sofa, a smart sound box, etc., and the shell thereof is covered with a decorative material such as leather, wood, textile, plastic, etc.

[0034] The display device includes a display panel 100, as shown in Figure 1 and Figure 2 The display panel 100 includes a display layer 1, a texture layer 2, a warming layer 3 and a substrate layer 4. The texture layer 2 is arranged on one side of the display layer 1, the warming layer 3 is arranged between the texture layer 2 and the display layer 1, and the substrate layer 4 is arranged on the side of the texture layer 2 away from the display layer 1.

[0035] The display layer 1 has a lighted state and an off state. In the lighted state, the light-emitting surface of the display layer 1 emits light, so as to present a display picture; in the off state, the light-emitting surface of the display layer 1 cannot emit light, so as to also not present a display picture.

[0036] The texture layer 2 is arranged on the display surface of the display layer 1, which is provided with a texture pattern, the texture pattern is the same as the texture of the decorative material covered on the shell of the display device, the light transmittance of the texture pattern when the display layer 1 is in the lighted state is greater than the light transmittance of the texture pattern when the display layer 1 is in the off state, so as to make the display layer 1 in the off state blend with the surrounding environment, hidden in the display device, so as to realize the integrated design, and improve the aesthetic degree of the display device.

[0037] The warming layer 3 is arranged on the side of the texture layer 2 close to the display layer 1, which is connected with the driving assembly 7 in the light-transmitting display panel 100, and can raise or lower its own temperature under the control of the driving assembly 7, so as to control the light transmittance of the texture layer 2 by changing the temperature of the warming layer 3.

[0038] Specifically, the reversible thermosensitive colorless ink is included in the preparation material of the texture layer 2, and is used to form the texture pattern and has a heating colorless effect. The color of the reversible thermosensitive colorless ink can be changed by heating the texture layer 2, that is, the light transmittance of the reversible thermosensitive colorless ink is proportional to the temperature of the heating layer. Under the heating effect of the heating layer 3, the texture pattern in the texture layer 2 has a hidden state and an appearance state, and the light transmittance of the reversible thermosensitive colorless ink in the hidden state is greater than that in the appearance state.

[0039] When the display layer 1 is in the lighting state, the driving assembly 7 is connected to the heating layer 3, so as to control the heating layer 3 to rapidly heat up. The heat in the heating layer 3 is conducted to the texture layer 2, so as to cause the reversible thermosensitive colorless ink in the texture layer 2 to be colorless, that is, to be converted from colored to colorless (transparent). The texture pattern in the texture layer 2 is colorless and transparent, and is in the hidden state, so as to prevent the texture pattern in the texture layer 2 from shielding the picture displayed by the display layer 1, to enhance the display effect, and to improve the user experience.

[0040] When the display layer 1 is in the closed state, the driving assembly 7 is disconnected from the heating layer 3, so as to cause the temperature of the heating layer 3 to decrease, and to stop heating the texture layer 2. After the temperature in the texture layer 2 decreases to a certain temperature, the reversible thermosensitive colorless ink in the texture layer 2 reappears color, that is, is converted from colorless (transparent) to colored. The texture pattern in the texture layer 2 reappears, and is in the appearance state, so as to hide the display layer 1 by the texture pattern in the texture layer 2, and to cause the light-transmitting display layer 1 to be integrated with the surrounding environment.

[0041] In the embodiment, the reversible thermosensitive colorless ink has a heat colorless temperature of 15-65℃. Preferably, the reversible thermosensitive colorless ink has a color change temperature of 40℃ or higher, for example, 45℃ or 50℃, so as to avoid the influence of normal temperature weather on the reversible thermosensitive colorless ink, and to avoid the temperature being too high to cause the display layer 1 to age rapidly at high temperature, and to prolong the service life. Similarly, the user can be effectively prevented from being scalded by high temperature when operating, and the user safety is protected.

[0042] Further, the heating layer 3 is provided with a plurality of heating traces 31, which are intersected and form a mesh structure. The temperature of the heating traces 31 when the display layer 1 is in the lighting state is higher than the temperature of the heating traces 31 when the display layer 1 is in the off state, and the orthographic projection of the heating traces 31 on the display layer 1 coincides with the orthographic projection of the texture pattern in the texture layer 2 on the display layer 1, so that the texture layer 22 can be accurately heated by the heating layer 3 to achieve the color-eliminating effect of the reversible heat-sensitive color-eliminating ink. Preferably, the mesh structure formed by the intersected heating traces 31 is the same as the structure of the texture pattern in the texture layer 2. The material of the heating traces includes metal, which can be silver, aluminum, copper, or other metals with excellent heat conduction performance. The metal has fast heat conduction and rapid heating and good heat dissipation performance, can quickly heat when the display layer 1 is in the lighting state, and promote the texture layer 2 to quickly enter the hidden state. The metal can also quickly dissipate heat and absorb the heat dissipation of the texture layer 2 when the display layer 1 is in the off state, so that the texture layer 2 quickly switches to the appearance state, and improves the user experience.

[0043] In order to further improve the display effect, in the embodiment, the heating traces 31 are nanoscale traces with a line width less than or equal to 1 micrometer, thereby reducing the influence of the heating traces 31 on the light transmittance of the display panel 100, and the nanoscale traces are invisible to the human eye, thereby not affecting the display effect of the display panel 100. Preferably, the line width of the heating traces 31 can be one of 5 nanometers, 7 nanometers, 20 nanometers, or 30 nanometers.

[0044] In the embodiment, the display panel 100 has a display area 101 and a non-display area 102 connected to the display area 101, and the picture is only presented in the display area 101, and the non-display area 102 cannot present the display picture. The texture layer 2 and the heating layer 3 are located in the display area 101 of the display panel 100, and the non-display area 102 of the display panel 100 can be directly shielded by pasting a decorative material on the outside of the display device, thereby reducing the production cost of the product.

[0045] The substrate layer 4 is arranged on the surface of the texture layer 2 away from the display layer 1, which is used to protect the surface of the display panel 100, improve the impact resistance and wear resistance of the display panel 100, and thereby improve the service life of the display panel. Preferably, the material of the substrate layer 4 can be a hard substrate such as a glass substrate or a quartz substrate.

[0046] Further, the display panel 100 further includes a support layer 5 and a light-transmitting ink layer 6.

[0047] The support layer 5 is arranged between the texture layer 2 and the warming layer 3, and is made of one or more of glass, light-transmitting inorganic material or light-transmitting organic material. The support layer 5 is used to support the texture layer 2 and flatten the surface of the warming layer 3 towards the texture layer 2, thereby reducing the difficulty in manufacturing the texture layer 2. Preferably, the support layer 5 is made of ultra-thin glass with a thickness of 0.1-1.1 mm, so that the support layer 5 has the support ability and reduces the influence of the support layer 5 on the heat conduction between the texture layer 2 and the warming layer 3.

[0048] The light-transmitting ink layer 6 is arranged between the display layer 1 and the warming layer 3 and is made of semi-transparent ink (light transmittance less than 75%). When the display layer 1 is in the lighting state, the light emitted by the display layer 1 can pass through the light-transmitting ink layer 6 and clearly display the pattern. When the display layer 1 is in the off state, the light-transmitting ink layer 6 blocks the display layer 1 located thereunder, thereby reducing the presence of the display layer 1 in the off state.

[0049] In the display panel, the texture layer capable of changing the light transmittance and color by temperature is arranged, so as to adapt to the lighting state and the off state of the display layer. Under the control of the temperature, the texture layer can eliminate the decorative pattern when the display layer is lighted, so as to enhance the display effect and improve the use experience of the user. The texture layer can also display the decorative pattern again when the display layer is off, so as to integrate the display layer with the surrounding environment and improve the aesthetic degree of the display device.
