[0034] The touch screens of electronic devices such as mobile phones, smart watches, and bracelets are basically a layer of ITO material for touch control bonded to the tempered glass, and the capacitance change on the ITO material is sensed by the touch chip on the circuit board. However, the process of bonding the ITO material to the tempered glass is relatively complex and delicate, resulting in a high production cost for the touch screen.

[0035] In order to solve the above problems, Figures 1 to 3 As shown, the embodiment of the utility model first provides a touch screen to simplify the process and reduce the cost.

When the user presses the key block 33 provided on the transparent part 31, the capacitance value at the key block 33 will change accordingly. The control component can read the capacitance value change of the ITO color film 3 and convert it into a corresponding signal to send a corresponding instruction to the display screen 2 to control the display content of the display screen 2, so that the screen touch effect of the display screen 2 can be achieved while ensuring the normal display of the display screen 2. In addition, the ITO color film 3 is set separately, and there is no need to process the ITO material onto the tempered glass, so that the overall structure of the touch screen is simple, the process is simplified, and it is easy to produce and assemble, thereby reducing the cost of the touch screen.

[0038] The display screen 2 can be set as a TFT screen, an LED screen or an OLED screen to be suitable for different types of screens. In addition, the control unit can include a circuit board and a touch chip and a micro control unit arranged on the circuit board. The touch chip can read the capacitance value of the ITO color film 3 in real time. When the touch chip reads that the capacitance value of the ITO color film 3 changes, the touch chip converts the capacitance value change into a corresponding signal and transmits the signal to the control unit. After receiving the signal, the micro control unit sends a corresponding instruction to the display screen 2 to control the display content of the display screen 2.

[0039] like Figure 2 As shown, the housing 1 is provided with an installation cavity 14, and the control component is arranged in the installation cavity 14 to avoid the control component from being exposed, so as to protect the control component.
