[0022] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0023] This application proposes a touch screen display with variable button light colors. Figure 1 and Figure 2 , including: a backlight assembly 10, an electrochromic layer, a cover plate 11, a display assembly 12, a touch sensor functional layer 20 and a button. The backlight assembly 10, the display assembly 12, the touch sensor functional layer 20 and the cover plate 11 are connected in sequence. The touch sensor functional layer 20 is provided with buttons, and the backlight assembly 10 provides lighting for the display assembly 12 and the buttons, so that the display assembly 12 can display a picture of a certain brightness, and the buttons are also illuminated by light, making it easier for users to identify the buttons with their naked eyes. An electrochromic layer is provided around the buttons along the optical path of the backlight assembly 10, and the electrochromic layer is provided below the buttons, and the light emitted by the backlight assembly 10 needs to pass through the electrochromic layer to reach the buttons. Among them, the touch sensor functional layer 20 is used for touch control, and the electrochromic layer is used to adjust the color change of the buttons. When the main board or solar charging layer supplies power to the electrochromic layer, the electrochromic layer can reversibly adjust its own optical properties, so that the color of light irradiated on the key is diversified, and the use of light colors in different environments during the day and at night can be realized. Preferably, the cover plate 11 is a LENS cover plate.

[0024] It should be noted that the electrochromic layer refers to the phenomenon that the optical properties of the material, such as reflectivity, transmittance, and absorptivity, undergo stable and reversible color changes under the action of an external electric field, which is manifested in the reversible changes of color and transparency. The electrochromic layer undergoes an electrochemical redox reaction under the action of an external electric field, gaining and losing electrons, causing the color of the material to change.

[0025] In one embodiment, the touch display screen with a key light that can change color also includes a solar charging layer, which is arranged on the side of the touch sensor functional layer 20 close to the display component 12. The solar charging layer supplies power to the electrochromic layer, so that the product has a self-charging function, improves energy utilization, increases product endurance, and reduces power consumption. Furthermore, the touch display screen with a key light that can change color also includes a rechargeable battery, and the solar charging layer is electrically connected to the battery, so that the solar charging layer converts excess electrical energy and stores it in the rechargeable battery. At night or on cloudy days, the rechargeable battery can supply power to the electrochromic layer.

[0026] For further information, see Figure 2 The touch display screen with a key light that can change color also includes a touch FPC 30, and the metal pins of the touch sensor functional layer 20, the metal pins of the solar charging layer, and the metal pins of the electrochromic layer are respectively bound and contacted with the touch FPC 30.

[0027] In addition, the touch FPC 30 is provided with a charging pin interface 31 to directly supply power to the electrochromic layer, or to charge a rechargeable battery, so that the power supply mode of the electrochromic layer is more diversified to meet the needs of users.

[0028] In one embodiment, see Figure 2 The touch sensor function layer 20 is provided with a pattern layer 21 above the key. The pattern layer 21 is designed to facilitate the user to visually identify the key with the corresponding function, and then perform touch operation on the key of the currently required function.

[0029] Furthermore, the cover plate 11 includes a visible area 111 and a non-visible area, wherein the visible area 111 is used for the display component 12 to display images, and the non-visible area is used to cover the messy components under the cover plate 11 to enhance the aesthetics. Among them, the non-visible area is provided with an ink layer on the side close to the display component 12, and the ink layer is black.

[0030] Furthermore, the size of the touch sensor functional layer 20 is larger than that of the display component 12, and the user's touch area on the touch display screen with changeable button lights is larger. The buttons can be set in the non-visible area without occupying the display screen of the visible area 111 and affecting the display effect. Moreover, when there is no light on the button, the button is integrated with the non-visible area and hidden in the non-visible area.

[0031] In addition, the touch display screen with a key light that can change color also includes OCA glue 40. One side of the touch sensor functional layer 20 is bonded to the visible area 111 of the cover plate 11 through the OCA glue 40, and the other side is bonded to the display component 12 through the OCA glue 40. The OCA glue 40 has good light transmittance and strong adhesiveness. The OCA glue 40 is used to connect the visible area 111 of the cover plate 11 to the display component 12, so that the internal structure of the cover plate 11 and the display component 12 is more stable.

[0032] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
