Description

Technical Field

[0001] This utility model relates to the field of touch display technology, and in particular to a touch display structure. Background Technology

[0002] Touchscreen displays, as the core interactive interface of modern electronic devices, have been widely used in smartphones, tablets, computer monitors, and many other fields. Touchscreen displays typically feature button icons, and conventional button designs often employ a semi-transparent black effect. That is, when the button backlight is off, the buttons appear uniformly black. However, since backlighting for these buttons can only provide white light, this results in a monotonous button color and insufficient aesthetic appeal. Meanwhile, with the advocacy of carbon peaking and green energy, and the development of green energy technologies, more and more green energy technologies will be applied to various products in our lives.

[0003] In view of the above, a touch display structure is provided that not only allows for changing the button color so that the buttons can display different colors when the light is on, but also has a self-charging function to reduce waste and increase product battery life. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a touch screen structure that not only enables the buttons to display different colors when the lights are on, but also has a self-charging function to increase the product's battery life.

[0022] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0023] Please see Figure 1 , Figure 2 and Figure 3 As shown, a touch display structure includes: a cover plate 100, a touch display 200, and a backlight assembly 300. The cover plate 100 has a viewing area and a frame area, and a button area is provided on the frame area. The touch display 200 is attached to one side of the cover plate 100, and an upper polarizer 210 is provided on the side of the touch display 200 facing the cover plate 100. An electrochromic functional layer is provided on the upper polarizer 210, which is located directly below the button area, and a solar charging functional layer is provided around the button area. The backlight assembly 300 is provided on the side of the touch display 200 away from the cover plate 100.

[0024] It should be noted that by setting an electrochromic functional layer and a solar charging functional layer on the upper polarizer 210 in the touch display screen 200, and placing the electrochromic functional layer directly below the button area, the button icons 111 on the button area can display different colors when the light is on through the electrochromic functional layer. At the same time, the solar charging functional layer enables the touch display screen structure to achieve self-charging function, saving energy and thus increasing the product's battery life. Specifically, the electrochromic functional layer uses existing electrochromic materials (electrochromic materials undergo electrochemical oxidation-reduction reactions under an applied electric field, gaining and losing electrons, causing the material's color to change). By coating the electrochromic material onto one side of the upper polarizer 210, when the light is on after power is applied, the button icons 111 on the button area can display a variety of different colors, making the touch display screen 200 more aesthetically pleasing. The solar charging functional layer generally includes conductive material layers and photoelectric conversion material layers (e.g., a combination of ITO, a-Si, molybdenum metal wires, etc.). The solar charging function is located in the non-button area, avoiding the viewing area. In this way, the buttons of the touch display screen structure can have an electrochromic function, while the touch display screen structure can also have a self-charging function, reducing waste, saving energy, and improving the product's battery life. Specifically, the touch display screen 200 also includes a display body 220 and a lower polarizer 230. The upper polarizer 210, the display body 220, and the lower polarizer 230 are stacked sequentially to realize the display function of the touch display screen 200 structure. In this embodiment, the upper polarizer 210 is bonded and fixed to the display body 220 by OCA optical adhesive. OCA optical adhesive has high light transmittance, high adhesion, and strong weather resistance, thus ensuring the connection stability between the cover plate 100 and the touch display screen 200, thereby improving the service life of the touch display screen 200 structure. The backlight assembly covers the upper polarizer, the display body, and the button area, and is attached to the back of the cover plate.

[0025] In one embodiment, a black ink layer 110 is provided in the border area. The black ink layer 110 is printed on the cover plate 100 and serves as a light-shielding and decorative element.

[0026] Furthermore, the button area is provided with multiple button icons 111, each button icon 111 is formed by hollowing out a black ink layer 110, and the button icon 111 is provided with a black semi-transparent ink 120. In this way, the light from the backlight assembly 300 can pass through the black semi-transparent ink 120 to display the button icon 111.

[0027] Furthermore, a touch sensor layer is provided on the side of the upper polarizer 210 facing the cover plate 100, and the touch sensor function covers the viewing area and the button icon 111. Thus, both the viewing area and the button icon 111 have touch functionality.

[0028] Furthermore, the electrochromic functional layer and the solar charging functional layer are disposed on the side of the upper polarizer 210 away from the cover plate 100. In this way, the solar charging functional layer can easily receive the light emitted by the backlight assembly 300, thereby realizing the conversion of the light emitted by the backlight assembly 300 into electrical energy for reuse.

[0029] Furthermore, an FPC400 is provided on the upper polarizer 210, and the metal pins of the touch sensor functional layer, the electrochromic functional layer, and the solar charging functional layer are respectively bonded and connected to the FPC400 to realize the bonding and conduction of each functional layer.

[0030] In one embodiment, the cover plate 100 and the touch display screen 200 are bonded together using optical adhesive. For example, OCA optical adhesive is used, which has high light transmittance, high adhesion and weather resistance, thus ensuring the stability of the connection between the cover plate 100 and the touch display screen 200, thereby improving the service life of the touch display screen 200 structure.

[0031] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
