New description: [New technical field] This creation has touch screen device and electronic device using the touch button device, especially for the touch button device and the use of the light-emitting element and the button position in the same area. The electronic device of the touch button device. [Prior Art] FIG. 1 is a schematic diagram of a touch button 100 of the prior art. As shown in Fig. i, the touch button 100 includes a light-emitting element 101, a light guide plate 103, and a button area 1〇5. As shown in Fig. 1, when the key area 105 is pressed, the light-emitting element 101 emits light, and then the light is guided to the key area 1 () 5 by the light guide plate 103. However, such a structure has the disadvantage that the light-emitting element 101 and the key area 105 are separated, which is complicated in the manufacturing process and requires the cost of the light guide plate 103, and the light-emitting element 101 and the key area 1〇5 often require different power sources. [New content] Therefore, one of the purposes of the present invention is to provide a touch button device in which the touch area and the light-emitting element are in the same area. The embodiment of the present invention discloses a touch button device having a touch light emitting surface, a touch sensing conductor 'a touch sensing element, and a light emitting element below the touch light emitting surface'. When the touch-object touches, the touch-sensitive element will detect the loss of the touch-sensitive inductor, and the rib depends on the light-emitting element M381114. Further, an electronic device including the above touch button device is disclosed. According to the above embodiment, the touch button, the light-emitting element, and the touch-sensitive conductor can be located in the same area (or the light-emitting element is between the touch button and the touch-sensitive conductor). This simplifies the process and makes the peripheral circuits easy to design. Embodiment 2 FIG. 2 is a schematic diagram showing the principle of operation of a touch button device according to an embodiment of the present invention. According to this picture, you can understand the concept of this creation. As shown in FIG. 2, the touch button device according to the embodiment of the present invention may include an input area 201 and an output area 203. The input area 201 includes a plurality of sensing areas 205, 207, and 209, and the output area 203 includes a plurality of Light-emitting elements 213, 215, and 217. The sensing area 205, 207 or 209 is touched (e. In one embodiment, the touch sensing device 21A can include a touch sensing conductor and a touch sensing component, wherein the touch sensing system senses whether the touch key device is touched by an object, and the touch sensing component is The change of the capacitance value of the touch sensing conductor is detected, so as to determine whether the sensing area 2〇5, 2〇7 or 2〇9 is touched. The illuminating control element 212 receives the signal from the touch sensing element in the touch sensing device 210 and determines whether the illuminating element or 217 is illuminated. In one embodiment, the touch sensing device and the illumination control element 2 are integrated in a control π (integrated circuit). Fig. 3 is a schematic view showing the touch button 3 (8) according to the embodiment of the present invention. As shown in FIG. 3, the touch button 300 includes a touch light emitting surface 3〇1, a touch sensing body 3体3 (ie, a touch sensing conductor in the touch sensing splitting diagram in FIG. 2) A light-emitting element 305. The touch sensing conductor 3 〇 3 is used to sense whether the touch illuminating surface view is '# body (for example, a human finger), and the illuminating element 305 is located below the touch illuminating surface, preferably just below the middle, further The touch-sensitive light-emitting surface 303 is not coplanar, and the light-emitting element 305 is surrounded by the touch-sensitive conductor 3〇3. When the touch-sensitive conductor 3〇3 is touched, the touch hair surface is touched. When the 301 is touched by an object, the touch sensing element (ie, the touch sensing element in the touch sensing device 210 in FIG. 2) detects the change in capacitance of the touch sensing conductor 303, thereby determining the touch light emitting surface 301. For the object to touch, and then provide - signal to the illuminated J element (ie, the illumination control element added in Figure 2), and then the illumination control element determines whether the illumination element is (open) or dark (off). In other words, the illuminating control element determines the point u of the illuminating element. For example, when the illuminating element go; when not illuminating, if the touch sensing conductor 3 〇 3 senses being touched, then the illuminating element 305 will be activated to emit Light. If the light-emitting element 3〇5 is already in the light state and touch When the touch-sensitive conductor 3〇3 is touched, the light-emitting element 3〇5 will be turned off to stop emitting light. At least part of the light emitted by the light-emitting element 3〇5 will pass through the touch light-emitting surface 301, and thus The touch light-emitting surface 301 can be regarded as a light-emitting area. In an embodiment, the touch-sensing conductor 303 is a capacitive sensing detection point, when the user's finger touches the touch light-emitting surface 3〇1, The inductive-charge value is touched through the touch-emitting surface to the touch-sensitive conductor, thereby causing a change in capacitance. The touch-sensing element detects a change in capacitance and senses that the touch-emitting surface 301 is touched. All of the 疋 can cause the touch sensing conductor to sense a charge value that can be used to activate the touch illuminating surface, and is not limited to a part of the human body.
