[0029] The embodiment of the utility model provides a touch display component, such as Figure 1 and Figure 2 As shown, the touch display film 100, the display box 200, the circuit board 300 and the back cover 400 are included. The touch display film 100 is fixed to the front side of the display box 200, the back side of the display box 200 is provided with a receiving groove to accommodate other components, the circuit board 300 is fixed in the receiving groove, and the back cover 400 is fixed on the display box 200 and covers the receiving groove to provide dust protection for the components inside the receiving groove.

[0030] The touch display film 100 includes a display film 110 and a touch film 120 that are pasted together. The display film 110 can be arranged on the front side of the touch film 120 or on the back side of the touch film 120. The surface of the touch display film 100 has a touch key area 111 and an information display area 112. The touch key area 111 can form specific numbers, words, patterns or pictures for users to perform touch operations. For example, the touch key area 111 can include a power button, an unlock button, an alarm button, a temperature adjustment button, etc. The information display area 112 can form specific numbers, words or patterns. When the information display area 112 is lit, corresponding information can be displayed, for example, by lighting up the corresponding numbers to display the temperature and time, by lighting up the corresponding patterns to display the opening or closing of a certain function, by lighting up the corresponding patterns to display the working status of the electrical product, etc. The display film 110 can form the above-mentioned touch key area 111 and the information display area 112 by reserving blank areas so that the lights can illuminate these areas. When the user touches the touch key area 111, the touch film 120 can cause the corresponding voltage signal to change, thereby obtaining the user's touch operation. The touch display film 100 has a first opening 113 that runs through it.

[0031] The front side of the display box 200 is respectively provided with a first through hole 211, a second through hole 212 and a second opening 213 corresponding to the touch key area 111, the information display area 112 and the first opening 113. Specifically, each touch key area 111 corresponds to at least one first through hole 211, the information display area 112 corresponds to at least one second through hole 212, and the second opening 213 corresponds to the first opening 113. The first through hole 211, the second through hole 212 and the second opening 213 all penetrate to the receiving groove. A light-emitting module corresponding to the first through-hole 211 and the second through-hole 212 and a liquid crystal display screen 600 corresponding to the second opening 213 are fixed on the circuit board 300. Each first through-hole 211 and each second through-hole 212 corresponds to a light-emitting module. The light-emitting module includes a plurality of lamp beads 500. When the lamp beads 500 emit light, the light can be irradiated onto the touch display film 100 through the first through-hole 211 and the second through-hole 212. The liquid crystal display screen 600 is arranged in the second opening 213 and leaks out of the first opening 113 to display information.

[0032] In this embodiment, the user can operate the touch button area 111 on the surface of the touch display film 100 to form a touch button that can be touched and operated by the user. The lamp bead 500 can illuminate the touch button area 111 and the information display area 112 through the first perforation 211 and the second perforation 212 respectively, so as to perform conventional information display; at the same time, information is further displayed through the liquid crystal display 600; therefore, the display component of this embodiment integrates touch buttons, information display functions and liquid crystal displays, enriches the display mode, and improves the user experience.

[0033] In some embodiments, the size of the first opening 113 is smaller than the size of the second opening 213. Specifically, if the first opening 113 and the second opening 213 are both square openings, the length and width of the first opening 113 are respectively smaller than the length and width of the second opening 213. If the first opening 113 and the second opening 213 are both circular openings, the radius of the first opening 113 is respectively smaller than the radius of the second opening 213. This allows the touch display film 100 to have a portion extending to the second opening 213, and this portion forms a frame around the second opening 213. The frame covers the frame 610 of the liquid crystal display screen 600, so that the portion of the liquid crystal display screen 600 that is displayed is exposed to the first opening 113. The frame 610 of the liquid crystal display screen 600 is blocked by the touch display film 100, thereby improving the display effect and enhancing the aesthetics of the overall appearance.

[0034] In some embodiments, in the forward direction, that is, in the direction from the back side of the display box 200 to the front side of the display box 200, the cross-sectional area of ​​the first perforation 211 and the second perforation 212 gradually increases, which is equivalent to the gradual increase in the aperture. This structure prevents the openings of the first perforation 211 and the second perforation 212 on the back side of the display box 200 from being too large. The light from the lamp bead 500 is reflected after being irradiated onto the side walls of the first perforation 211 and the second perforation 212, which can increase the brightness of the light and improve the display effect.

[0035] In some embodiments, the touch film 120 has a first cable 121, which is used to transmit electrical signals. The front side of the display box 200 is provided with a cable hole 221 that penetrates the receiving groove. The first cable 121 passes through the cable hole 221 and is connected to the circuit board 300, so that the touch film 120 can be connected to the touch display circuit on the circuit board 300.

[0036] Among them, the front side of the front side of the display box 200 may be provided with a groove, and the touch display film 100 may be embedded in the groove to keep the front side of the display box 200 relatively flat, and the wire hole 221 may be provided in the groove, thereby, the touch display film 100 will cover the first row of wires 121, so that the surface of the touch display film 100 is flat, and the visual effect of the appearance is improved.

[0037] In some embodiments, both sides of the display box 200 have an outwardly extending mounting portion 230, and the mounting portion 230 is used to be fixed at a preset mounting position to install and fix the entire display assembly. The mounting portion 230 can be an extension of the front side plate of the display box 200, or it can be two mounting plates respectively fixed on both sides of the display box 200.

[0038] Furthermore, a mounting groove 231 is provided on the front side of the mounting portion 230, and a through mounting hole 232 is provided in the mounting groove 231. A screw or other connecting member can be passed through the mounting hole 232 and then fixed to a preset mounting position, thereby fixing the entire display assembly. The mounting groove 231 can accommodate the head of a screw or other connecting member, thereby preventing the head of the screw or other connecting member from protruding from the surface of the mounting portion 230, and relatively improving the flatness of the surface of the mounting portion 230.

[0039] In some embodiments, at least a portion of the information display area 112 is a digital tube display area, and the second perforation 212 corresponding to the digital tube display area and the lamp beads 500 included in the light-emitting module are distributed in a digital tube shape. In this way, a portion of the information display area 112 will form the effect of a digital tube display screen to display a variety of numbers or letters, enrich the displayed content, and further enhance the display effect.

[0040] In some embodiments, a pad is fixed to the rear side of the LCD screen 600, and the pad is glued and fixed to the front side of the circuit board 300 to prevent the LCD screen 600 from being directly attached to the circuit board 300, providing sufficient heat dissipation space for the LCD screen 600, thereby facilitating heat dissipation of the LCD screen 600.

[0041] In some embodiments, the circuit board 300 is a double-sided printed circuit board, and the rear side of the double-sided printed circuit board is fixed with electronic components for forming a touch display circuit, the electronic components including but not limited to resistors, capacitors, inductors and chips, thereby reducing the space occupied by the front side of the circuit board 300, so that more lamp beads 500 can be fixed on the front side of the circuit board 300, so as to have more touch button areas 111 and information display areas 112, so as to facilitate human-computer interaction.

[0042] Furthermore, the LCD screen 600 has a second row of cables 620, and the double-sided printed circuit board is provided with a through hole. The second row of cables 620 passes through the through hole and is further connected to the touch display circuit on the rear side of the double-sided printed circuit board to drive the LCD screen 600 to work.

[0043] In some embodiments, the back cover 400 can be fixed on the display box 200 in a detachable manner to facilitate assembly and disassembly and reduce the workload of later maintenance. For example, the back cover 400 can be fastened to the display box 200 by screws.
