The display screen 212 is located on the body 211. The button structure 22 includes at least a plurality of buttons 221, a plurality of light-emitting elements 222, and a processing unit 223. The buttons 221 are made of a thermoelectric material, each button 221 has a pre-pattern 224, and the button 221 is On the body 211. Light-emitting element form number A0101 Page 6 of 22 [0015] [0016] [0019] [0020] [0020] 096145794 On September 30, 099, the replacement page 222 is located in the body 2Π, and each The position of a light-emitting element 222 overlaps with the position of each button 221, and each light-emitting element 222 is adjacent to each button 221. The processing unit 223 is located in the body 211 and is electrically connected to the display screen 212, the light-emitting element 222, and the button 221 . When the user touches (abuts) the finger 23 on one of the buttons 221, the button 221 senses the heat energy emitted by the user's finger 23 by the thermoelectric material characteristic, so that the button 221 generates an inductive signal, and The sensing signal is transmitted to the processing unit 223. After the processing unit 223 determines the position of the button 221, the light-emitting element 2 2 2 corresponding to the position of the button 221 is controlled to emit light. Then, when the finger 23 further presses the button m of the same button, the button 221 generates the pressing processing unit 223, and then the processing unit 223 determines the button 221 corresponding to the pressing signal and the predetermined reservation thereon. The pattern 224' is converted into an input signal and displayed on the display screen. Fig. 3 is a flow chart showing the method of using the electronic device according to the above embodiment; The electronic device has a display screen and the display screen is located on the body. Referring to FIG. 3, the method of using the method is as follows: Step 31: providing a plurality of buttons, a plurality of light-emitting elements, and a processor, wherein a position of each of the light-emitting elements overlaps with a position of each button (corresponding), and The buttons, the light-emitting elements, and the display screen are electrically connected to the processing unit. Step 32. The user touches (abuts) one of the buttons with a finger. Step 33. The form number of the button is sensed by the characteristics of the thermoelectric material Α0101 Page 7 / Total 22 pages 0993352532-0 [0022] [0022] I 099 Q9S 3Q 日纽_Page 1 [0023] [0024 [0028] [0028] 096145794 thermal energy and generate an inductive signal. Step 34: Send the sensing signal to the processing unit, so that the processing unit determines the location of receiving the sensing signal. Step 35: The light-emitting element corresponding to the button is controlled by the processing unit to emit light. Step 36: The user greets whether the button to which the button is pressed is the button to be input. If no, go back to step 32. If yes, proceed to the next step. Step 37: The user presses the pressed button with the finger to cause the button to generate a pressing signal to be transmitted to the processing unit, and then the processing unit determines that the button corresponding to the pressing signal and the button represent a lack of: The pattern signal, .;· .·''* .... . is converted into an input signal and displayed on the display screen. ::- .r ; ' The button structure of the above electronic device is preferably that the display screen has a small screen.

The electronic device has a body, a display screen and a small screen, and is displayed. The screen is on the body and the small screen is on the display screen. Please refer to FIG. 5, and the usage method is as follows: Step 51: provide a plurality of buttons, a plurality of light-emitting components, and a processor, each of the light-emitting components corresponding to each button, and the buttons, the light-emitting components, and the display screen system. It is electrically connected to the processing unit. 096145794 Form No. A0101 Page 9 of 22 0993352532-0 [0033] 1334152 [0035] Step 52: The user corrects the replacement page with a finger on September 30, 099, and is buried on one of the buttons. [0036] Step 53: By thermoelectric energy, and generating a step 54: transmitting the sensing positional material characteristic of the sensing signal causes the button to sense the sensing signal emitted by the finger. The signal is sent to the processing unit, so that the processing unit judges the connection step 55: the button unit displays the predetermined « on the button on the small screen. [0040] [0042] [0042] [0042] Step 56. The processing unit 70 controls the illumination of the illumination unit corresponding to the button, and the other illumination elements surrounding the illumination member. In step 57, the user confirms whether the button of the button (4) is the button to be input. If no, go back to step 52. If yes, go to the next step. Step 58: The user presses the pressed button with the finger to transmit the button generating-pressing signal to the processing unit, and after the processing unit confirms the pressing signal, the corresponding button win button represents the predetermined pattern number. After being converted into a round signal, it will be displayed on the display screen. It can be seen from the above that the improved feature of the present invention is that when the user + & is pressed against its t-button, the processing unit controls the light-emitting component corresponding to the button and the other light-emitting elements around the light-emitting component. The illuminating element is used to improve the conventional technique. When the finger touches the button, the rest of the buttons of the mobile phone are illuminated together, resulting in a problem of high power consumption. In addition, the user can pre-display through the small screen to confirm whether the button to which the finger is pressed is the button to be input, and then input the signal to the electronic device by pressing the button, thereby improving the conventional skill, the finger touches the form No. A0101 Page 10 of 22 0993352532-0 1334152 When the page is being replaced by the shuttle button on September 30, 2009, the electronic device judges that the user inputs the button signal, which is liable to cause a mistake. [0043] The foregoing is illustrative only and not limiting. Any equivalent modifications or alterations to the spirit and scope of the invention are intended to be included in the scope of the appended claims.
