Problems solved by technology

[0004] However, when the user's finger 12 is attached to the button 113, the button area 13 where the button 113 is located will be completely illuminated, which will easily cause a waste of power, and the button 113 will not be confirmed by the user. Thermal energy, it is judged that the input signal is sent to the mobile phone, and it is easy to cause the input signal not to be input by the user.

Embodiment Construction

[0096] The button structure of the electronic device of the present invention. The electronic device has a body and a display screen, and the display screen is located on the body. The button structure includes a plurality of light-emitting components, a processing unit and several buttons. The light-emitting component is located inside the body. The processing unit is located in the body and is electrically connected with the light-emitting component and the display screen. The buttons are electrically connected to the processing unit, and are located on the body, and each button corresponds to each light-emitting component. Wherein, when the user leans against one of the keys, the key senses the heat energy emitted by the user to generate an induction signal, and the light-emitting component corresponding to the key emits light. When the user presses the button, a pressing signal is generated, and the processing unit receives the pressing signal, converts the pressing sig...

Abstract

The invention discloses a key structure of an electronic device. The electronic device is provided with a body and a display screen, and the display screen is positioned on the body. The key structure comprises a plurality of luminous components, a processing unit and a plurality of keys. The luminous components are positioned in the body. The processing unit is positioned in the body and electrically connected with the luminous components and the display screen. The keys are electrically connected with the processing unit and positioned on the body, and each key corresponds to each luminous component. When a user is close to one of the keys, the key induces thermal energy released by the user to generate an induction signal, and then the luminous component corresponding to the key lightens. When the user presses the key to generate a press signal, the processing unit receives the press signal, and converts the press signal into an input signal to be displayed on the display screen.

Description

technical field [0001] The present invention relates to a button structure and its usage method, in particular to a button structure for electronic devices and its usage method, which utilizes the property of emitting light by thermally sensing user's thermal energy. Background technique [0002] Please also refer to Figure 1A to Figure 1B , which respectively show a three-dimensional cross-sectional view of a thermal touch keyboard of a known electronic device, and a schematic diagram of its operation. In the figure, the known electronic device 11 is a mobile phone, and it has a main body 111 , a display screen 112 , several buttons 113 and a plurality of light emitting components 114 . Both the display screen 112 and the buttons 113 are located on the main body 111 . The buttons 113 are made of a pyroelectric material, and each button 113 has a predetermined pattern 115 on it. The light emitting component 114 is disposed in the body 111 and is electrically connected to ...
