[0030] The coating layer 2 of the embodiment is non-conductive brightening layer, which can increase the brightness of the display panel, make the display picture of household electrical appliances brighter and clearer, and have better display effect under different ambient light, for example, in the brightly lit living room, users can clearly see the display content.

[0031] The etching layer 4 and the optical texture layer on the outer surface of the glass substrate 1 of the embodiment cooperate with each other to scatter and refract light, so that the light propagates more uniformly on the surface of the panel, the reflection and glare of the light are reduced, the interference of external light on the display picture is reduced, the contrast and viewing angle of the picture are improved, and the user can obtain a better visual experience when viewing from different angles. The optical texture layer can be designed into various different texture patterns to bring a unique optical appearance effect to the household appliance display panel 7, increase the aesthetic and fashion of the product, and make the household appliance become a decorative item when not displaying content, thereby improving the overall quality and artistic value of the household appliance.

[0032] More preferably, the etching layer 4 comprises a photosensitive glue coated on the outer surface 12 of the glass substrate 1; the outer surface of the etching layer 4 has an optical texture layer formed by chemical etching, the height of the corresponding texture in the optical texture layer is any value in the range of 1 to 10 microns; and the optical texture layer is obtained by etching after the texture pattern is developed on the glass coated with the photosensitive glue by using a laser developing plate making machine.

[0033] The texture height of 1 to 10 microns can accurately control the scattering and refraction angles of light. In different ambient light, the light can be uniformly scattered, and the reflection glare is reduced. The laser developing plate making machine can realize high-precision texture pattern making, so that the modulation of the display panel on the light is more fine, thereby improving the delicacy and level of the display picture, and making the details of the image more rich and the color transition more natural.

[0034] Compared with the traditional plate making method, the laser developing plate making machine has higher production efficiency and precision. The designed texture pattern can be quickly and accurately transferred to the glass, the error of manual operation is reduced, and large-scale industrial production is facilitated. The chemical etching process cooperates with the laser developing plate making, has good process stability and repeatability, and can ensure that the optical texture layer of each display panel has consistent quality and performance in large-scale production, thereby reducing the product failure rate. The photosensitive glue as part of the etching layer 4 can enhance the bonding force between the glass substrate 1 and the optical texture layer. The optical texture layer is more firmly attached to the glass surface and is not easy to fall off or be damaged, thereby improving the durability and reliability of the display panel and prolonging the service life of the product. The optical texture layer after the chemical etching and laser developing treatment has a specific microstructure on the surface, which improves the corrosion resistance and wear resistance of the display panel to a certain extent. The optical texture layer can resist scratches, stains and chemical erosion in daily use, and maintain the appearance and performance of the display panel.

[0035] More preferably, the pattern of the optical texture is a periodic arrangement of texture shapes, the texture shapes being any one of a circle, a square or a triangle.

[0036] More preferably, the etching layer 4 comprises a first region and a second region, the first region being an optical texture region 41; the second region being provided with a transparent region 42.

[0037] The optical texture of the first region can scatter, refract and the like of light, optimizing the display effect, such as reducing reflection glare, increasing the viewing angle and the like; the transparent region 42 of the second region can ensure the direct transmission of light at a specific position, for example, when displaying important information or operation prompts, the transparent region 42 can be used to realize clear display without interference, making the display content more hierarchical and flexible. The transparent region 42 here is essentially a corresponding dynamic display region, which can enable the subsequent display module to display, and can realize dynamic interaction with the user through the region.

[0038] A specific pattern or texture can be designed in the optical texture region 41, combined with the transparent region 42, to create a unique visual effect, such as presenting an artistic painting or decorative pattern effect when the display panel is turned off, improving the overall appearance and artistic sense of the household appliance. The transparent region 42 can provide better light transmission conditions for functional components such as touch sensors, ensuring the accuracy and sensitivity of touch operation. When performing touch operation, light can pass through the transparent region 42 more smoothly, allowing the touch sensor to better sense the touch action of the finger, improving the user's interaction experience with the household appliance display panel 7.

[0041] Specifically, during implementation, the color or transparency can be quickly and reversibly changed according to the change of the electrical signal. The display content and the background color can be dynamically switched, making the display picture more vivid and rich, and improving the user's visual experience. For example, the color and transparency can be automatically adjusted. The transmission and reflection of light can be adjusted by changing the color or transparency. In a strong light environment, the electrochromic layer can be changed to a dark color to reduce the interference of strong light on the display picture and improve the display contrast; in a weak light environment, it can be changed to a light color or transparent, increasing the display brightness and making the display content clearer.

[0042] If it is a thermochromic layer, it can change color according to the change of ambient temperature or its own temperature, and can be used as a temperature indicator to intuitively display the working temperature state of the household appliance. For example, when the internal temperature of the household appliance is too high, the thermochromic layer turns red, reminding the user to pay attention to heat dissipation and avoid damaging the equipment due to overheating, thereby improving the safety and reliability of the household appliance.

[0043] By utilizing the characteristics of the thermochromic layer, different appearance atmospheres can be created according to different environmental temperatures or user needs.

[0045] By adjusting the voltage signal between the first transparent electrode layer 51 and the second transparent electrode layer 53 through the control module, the molecular arrangement of the liquid crystal layer 52 can be accurately controlled, thereby realizing precise adjustment of the color and transparency of the display panel. According to different display contents and environmental needs, various colors and different degrees of transparency changes can be quickly and reversibly presented, making the display picture more rich and lively.

[0046] Specifically, the liquid crystal layer 52 can effectively control the transmission and blocking of light under the action of an electric field, and in combination with the high light transmittance of the transparent electrode layer, a high-contrast display effect can be realized.

[0047] The embodiment realizes dynamic changes of the texture by adding electrochromic or thermochromic materials. For example, when different voltages are applied, the texture shape, color or glossiness of the glass surface can change, bringing more interesting and interactive appearance to the household appliance.

[0048] More preferably, the cover bottom protective layer 3 includes a window area 32 and a base area 31, the base area 31 surrounds the window area 32, the window area 32 corresponds to the transparent area 42 in the longitudinal position, and the size of the window area 32 is the same as that of the transparent area 42.

[0049] In the embodiment, the base area 31 surrounds the window area 32, can block the stray light entering from the non-window area 32 such as the edge of the glass panel, reduce the scattering and reflection of light, improve the visual clarity of the window area 32, make the observation of the internal condition of the household appliance through the window area 32 more clear, and reduce the interference.

[0050] When the glass panel is subjected to external force, the cover bottom protection layer 3 can play a certain stress dispersion role, uniformly distribute the external force on the surface of the glass panel, avoid stress concentration to cause glass breakage, and improve the impact resistance of the glass panel.

[0051] More preferably, the number of the window area 32 is one or more. The user can set the corresponding window area 32 according to actual needs.
