[0030] With the increasing demand from customers for diverse design expressions and high-end aesthetics, higher requirements are being placed on the decorative design of display panels in home appliances and other fields. For example, the need to improve the concealment of display panels is becoming increasingly strong.

[0031] Current LCD screens often appear as a single black when not lit, making them visually difficult to blend into their surroundings and appearing rather jarring. If patterns are created on the LCD screen by applying an ink printing coating to the film, there is a risk that the brightness and clarity of the panel will decrease when it is lit.

The display panel 4 can also serve as a touch information input section, allowing users to operate the display device 2 by touching it, for example, for displaying and inputting information during interface navigation and function switching. The display device 2 also includes a housing 5, within which the display panel 4 is installed. The housing 5 protects the display panel 4 and reduces the risk of damage from external forces.

[0035] Please refer to Figure 2 , Figure 2 This is a schematic diagram of the structure of a display system according to one or more embodiments.

In some embodiments, the background device 3 may have a groove, and the display device 2 is embedded in the background device 3 through the groove, thereby making the outer shell of the display device 2 hidden in the background device 3, further improving the stealth effect of the display device 2. For example, the background device 3 is a background wall with a groove, and the display device 2 is embedded in the groove of the background wall.

[0037] Please refer to Figure 3 , Figure 3 This is a first structural schematic diagram of a display panel according to one or more embodiments.

[0038] To improve the aforementioned problems and enable the liquid crystal display screen to better integrate into its surroundings visually, this application provides a display panel 4. The display panel 4 includes a liquid crystal display layer 10, a first substrate 20, and an invisible decorative film 30. The liquid crystal display layer 10 includes a reflective layer 14. The first substrate 20 is disposed on the light-emitting side of the liquid crystal display layer 10. The invisible decorative film 30 is disposed on the side of the first substrate 20 facing away from the liquid crystal display layer 10. The invisible decorative film 30 receives an incident light beam 40, which includes a first incident light 41 and a second incident light 42. The first incident light 41 is reflected by the invisible decorative film 30, and the second incident light 42 is transmitted through the first substrate 20 to the liquid crystal display layer 10. The reflective layer 14 reflects at least a portion of the second incident light 42. The invisible decorative film 30 can be an optical decoration film (ODF). The invisible decorative film 30 can have good light transmittance. The invisible decorative film 30 can have certain surface effects, which can include at least one of texture, pattern, gloss, and color. In some applications, the invisible decorative film 30 may include a light-transmitting cover plate, a pattern layer, and an optical adhesive layer arranged sequentially. The optical adhesive layer may be located on the side of the first substrate 20 facing away from the liquid crystal display layer 10, for adhesion to the liquid crystal display layer 10. The pattern layer is used to display specific patterns to form a certain surface effect. The light-transmitting cover plate may be made of transparent or semi-transparent materials such as glass, allowing light beams to pass through and revealing the pattern layer. Simultaneously, the light-transmitting cover plate also protects the pattern layer, reducing the risk of damage. The surface effect of the invisible decorative film 30 may match the visual effect of the environment in the application scenario. For example, if the color of the application scenario is blue and has a spiral texture, the invisible decorative film 30 may also have a blue spiral pattern to visually blend into the environment. When the display panel 4 is lit, the user can observe the light-emitting side of the liquid crystal display layer 10 to appreciate the image displayed on the display panel 4. The first substrate 20 may be a glass substrate, disposed on the light-emitting side of the liquid crystal display layer 10, to improve the reflectivity of the display panel 4 to the incident light beam 40. Therefore, the invisible decorative film 30 is disposed on the side of the first substrate 20 away from the liquid crystal display layer 10, so that the liquid crystal display panel 4 can better blend into the surrounding environment in the user's viewing direction, thereby achieving the invisibility effect of the display panel 4.

[0039] The incident beam 40 can be a portion of the ambient light projected onto the display panel 4. The first incident light 41 in the incident beam 40 is reflected by the invisible decorative film 30, which has good light transmittance. Therefore, the remaining portion of the incident beam 40 can be transmitted through the invisible decorative film 30 to the first substrate 20, and then reflected by the first substrate 20. The remaining portion of the incident beam 40 is then transmitted through the first substrate 20 to the liquid crystal display layer 10 as the second incident light 42. The liquid crystal display layer 10 then reflects at least a portion of the second incident light 42, thereby increasing the reflectivity of the incident beam 40 of the display panel 4, thereby increasing the brightness of the display panel 4 and enhancing the stealth effect of the display panel 4.

[0040] In some embodiments, the liquid crystal display layer 10 further includes a second substrate 11 and a liquid crystal layer 12, with the liquid crystal layer 12 and the reflective layer 14 located between the first substrate 20 and the second substrate 11. The reflective layer 14 is closer to the first substrate 20 than the liquid crystal layer 12. The second substrate 11 may also be a glass substrate. The liquid crystal layer 12 may be made of liquid crystal. The reflective layer 14 may be made of materials including, but not limited to, aluminum, copper, etc. The reflective layer 14 is closer to the first substrate 20 than the liquid crystal layer 12 to better reflect at least a portion of the incident light, thereby improving the reflectivity of the incident light beam 40 of the display panel 4.

[0041] In some embodiments, the reflective layer 14 includes a metal electrode layer 141, the liquid crystal display layer 10 includes a transparent electrode layer 13, and the liquid crystal layer 12 is located between the transparent electrode layer 13 and the metal electrode layer 141. The transparent electrode layer 13 may be made of materials including, but not limited to, indium tin oxide. The metal electrode layer 141 can cooperate with the transparent electrode layer 13 to control the orientation and rotation of liquid crystal molecules in the liquid crystal layer 12, thereby changing the degree of light transmission and obstruction through the liquid crystal layer 12 to achieve a display effect. The metal electrode layer 141 has good light reflectivity, thus improving the reflectivity of the second incident light 42, thereby improving the brightness of the display panel 4. In some other embodiments, the reflective layer 14 includes a metal electrode layer 141, the metal electrode layer 141 being made of aluminum and copper, the transmittance at the center of the display panel 4 is 5.56%, the contrast ratio is 4100, and the reflectivity reaches 14.02 w / o plc.

[0042] In some embodiments, the liquid crystal display layer 10 further includes a color filter layer 15 and a black matrix 16, which are disposed on the side of the transparent electrode layer 13 facing away from the liquid crystal layer 12. The color filter layer 15 may include a red sub-filter layer, a green sub-filter layer, and a blue sub-filter layer, used to select the color of light transmitted through the color filter layer 15 to form pixel units. Depending on the combination of the red, green, and blue sub-filter layers for each pixel, the color of light can be easily adjusted, thereby enabling the display panel 4 to display a richly colored image. The material of the black matrix 16 may be a black organic dye or a black organic resin. The black matrix 16 can be located between the pixel units, preventing light leakage between the red, green, and blue sub-filter layers and preventing interference between the light from each pixel unit, thereby enhancing the contrast and clarity of the image.

[0043] Please refer to Figure 4 , Figure 4 This is a second structural schematic diagram of a display panel according to one or more embodiments.

[0044] In some embodiments, the liquid crystal display layer 10 further includes a second substrate 11 and a liquid crystal layer 12. The reflective layer 14 includes a black matrix 16, with the liquid crystal layer 12 and the black matrix 16 located between the first substrate 20 and the second substrate 11. The black matrix 16 is closer to the first substrate 20 than the liquid crystal layer 12, and is used to reflect at least a portion of the second incident light 42. In other embodiments, the black matrix 16 is used to reflect at least a portion of the second incident light 42, and the transmittance at the center of the display panel 4 is 5.53%, the contrast ratio is 4034, and the reflectance is 5.69 w / o plc. In other embodiments, the reflective layer 14 may also include a reflective coating, which may be disposed on the side of the black matrix 16 closer to the first substrate 20, further improving the reflectivity of the reflective layer 14 and facilitating the black matrix 16 to reflect at least a portion of the second incident light 42, thereby improving the stealth effect.

[0045] In some embodiments, the liquid crystal display layer 10 further includes a color filter layer 15, with a black matrix 16 disposed on the same layer as the color filter layer 15 and embedded therein. For example, the color filter layer 15 includes a red sub-filter layer, a green sub-filter layer, and a blue sub-filter layer, wherein the red, green, and blue sub-filter layers are spaced apart, and the black matrix 16 can be embedded in the spaces between them. This allows the black matrix 16 to further prevent light leakage between the red, green, and blue sub-filter layers and interference between the light from each pixel unit, thereby enhancing image contrast and clarity.

[0046] In some embodiments, the liquid crystal display layer 10 includes a metal electrode layer 141 and a transparent electrode layer 13, with the liquid crystal layer 12 located between the transparent electrode layer 13 and the metal electrode layer 141. The metal electrode layer 141 is closer to the second substrate 11 than the transparent electrode layer 13. The transparent electrode layer 13 may be made of materials including, but not limited to, indium tin oxide. The metal electrode layer 141 can cooperate with the transparent electrode layer 13 to control the orientation and rotation of liquid crystal molecules in the liquid crystal layer 12, thereby changing the degree of light transmission and obstruction through the liquid crystal layer 12 to achieve a display effect.

[0047] In some embodiments, the display panel 4 further includes a backlight layer 50, which is disposed on the side of the liquid crystal display layer 10 opposite to the first substrate 20. The backlight layer 50 may be, but is not limited to, a cold cathode fluorescent lamp, a light-emitting diode, etc. The backlight layer 50 can provide a light source for the display panel 4 to illuminate the display panel 4, thereby enabling the display panel 4 to emit light so that the image can be seen by an observer.

[0048] In summary, this application provides a display panel 4, which includes a liquid crystal display layer 10, a first substrate 20, and an invisible decorative film 30. The liquid crystal display layer 10 includes a reflective layer 14. The first substrate 20 is disposed on the light-emitting side of the liquid crystal display layer 10, and the invisible decorative film 30 is disposed on the side of the first substrate 20 opposite to the liquid crystal display layer 10. The invisible decorative film 30 is used to receive an incident light beam 40, which includes a first incident light 41 and a second incident light 42. The first incident light 41 is reflected by the invisible decorative film 30, and the second incident light 42 is transmitted through the first substrate 20 to the liquid crystal display layer 10. The reflective layer 14 reflects at least a portion of the second incident light 42. Therefore, the first incident light 41 in the incident beam 40 is reflected by the invisible decorative film 30. Since the invisible decorative film 30 has good light transmittance, the remaining portion of the incident beam 40 can be transmitted through the invisible decorative film 30 to the first substrate 20. The first substrate 20 then reflects a portion of the remaining incident beam 40, and the remaining incident beam 40 becomes the second incident light 42 transmitted through the first substrate 20 to the liquid crystal display layer 10. The liquid crystal display layer 10 then reflects at least a portion of the second incident light 42, thereby increasing the reflectivity of the incident beam 40 of the display panel 4, thus increasing the brightness of the display panel 4 and enhancing its stealth effect. Compared to other display panels, the display panel 4 provided in this application blends more easily into the surrounding environment, has a better stealth effect, and higher brightness.
