It can be understood that the touch electronic device 100 can also be other touch electronic devices, such as a tablet computer.

The glass panel 10 includes an inner side 11 and an outer side 12 opposite the inner side 11. The glass panel 10 has a central region 13 and an edge region 14 surrounding the central region 13. In the embodiment, the glass panel 10 is a glass panel located in front of the touch electronic device 100 .

The touch layer 20 is disposed in a central region 13 of the inner side 11 of the glass panel 10 . Place The touch layer 20 is a capacitive touch layer. It can be understood that the touch layer 20 can also be other types of touch layers, for example, a resistive touch layer. When the user touches the central region 13 of the outer side 12 of the glass panel 10, the capacitance at the corresponding contact position on the touch layer 20 changes, so that the frequency of the oscillator connected thereto changes. The touch position can be determined by measuring the frequency change. When the touch layer 20 senses the touch, a color change touch command is output.

The thermochromic pattern layer 30 may be disposed on the inner side 11 and/or the outer side 12 of the glass panel 10.

Alternatively, the heat source 42 may be other heat-generating electronic components in the touch electronic device 100, such as a processor, and is not limited to an independent heat source device that supplies heat to the thermochromic pattern layer 30. The heat generated by the processor is conducted to the thermochromic pattern layer 30 through the thermal conductive sheet 41.

The control module 50 is connected to the touch layer 20 and the heat source 42. When the control module 50 receives the color changing touch command sensed by the touch layer 20, the control module 50 controls the heat source 42 to generate heat. Further, the control module 50 determines the touch frequency according to the frequency of receiving the color change touch command, and controls the magnitude of the current input to the heat source 42 according to the touch frequency, thereby controlling the heat source 42. The amount of heat output. The higher the touch frequency, the greater the current input by the control module 50 to the heat source 42; the lower the touch frequency, the smaller the current input by the control module 50 to the heat source 42.

Alternatively, when the heat source 42 is another heat generating component, the heat source 42 may directly generate heat without setting the control module 50 to control the heat source 42.

The circuit board 60 is used to carry the control module 50. The heat generating unit 40 and the control module 50 are electrically connected through the circuit board 60. In this embodiment, the circuit board is a flexible circuit board.

The outer casing 70 has a rectangular parallelepiped shape including an outer surface 71 facing the glass panel 10 and an inner surface 72 opposite the outer surface 71. The inner side 11 of the glass panel 10 is in contact with the outer surface 71 of the outer casing 70.

The control module 50 and the circuit board 60 are located on the side of the inner surface 72 of the outer casing 70. The heat generating unit 40 may be in direct or indirect contact with the thermochromic pattern layer 30.

During the use, when the user touches the central area 13 of the outer side 12 of the glass panel 10, the touch layer 20 senses the touch of the user and outputs the color touch command to The control module 50 controls the heat source 42 to generate heat, and the heat conductive sheet 41 conducts heat generated by the heat source 42 to the thermochromic pattern layer 30, the thermochromic The color of the pattern layer 30 changes after being heated. When the user continuously touches the central area 13 of the outer side 12 of the glass panel 10, the control module 50 controls the magnitude of the current input to the heat source 42 according to the frequency of the received color-changing touch command, thereby causing the The thermochromic pattern layer 30 exhibits a variety of different colors.
