[Embodiment] The first preferred embodiment of the present invention, as shown in the first figure, includes: a printed circuit board (10); I a plurality of light-emitting members (100) spaced apart from each other in the printed circuit In the present embodiment, each of the light-emitting members (100) is a single white light-emitting diode, and an insulating member (101) is disposed between adjacent light-emitting members (100), and the insulating member (101) The light of the adjacent illuminating member (100) can be opened to prevent light leakage; and a glass substrate (20) is disposed on the bottom surface of the illuminating printed circuit board (1 〇) toward the illuminating members (1 ,). A transparent electrode layer (21) including a plurality of transparent electrodes (21〇) is disposed under the glass substrate (2〇), and the transparent electrodes (21〇) constitute a plurality of touch blocks capable of providing sensing, and the transparent portions are transparent. The electrodes (21〇) g correspond to the positions of the light-emitting members (彳〇〇) on the printed circuit board (1 〇), and each transparent electrode (21 0) transmits a signal to a driving chip when a weak electrostatic charge change is sensed. The driving chip drives the light-emitting member corresponding to the transparent electrode (2) 根据 according to the signal (1) 00) shines. The embodiment further includes a diffusion plate (30) disposed between the glass substrate (20) and the light-emitting members (1), so that the light emitted by the light-emitting member can be uniform. Dispersing, in addition, in this embodiment, a black matrix layer (4 〇) and a color filter (50) are disposed between the bottom surface of the glass substrate (20) and the transparent electrode (210), and are provided by a flat layer. (202) and the buffer layer (201) achieve planarization and insulation purposes. The flat layer (202) is made of epoxy resin or acrylic resin, and the high molecular weight is 5 M363641 molecular material; and the buffer layer (201) is made of dioxide.黑色(Si02); the black matrix layer (40) is formed with a button pattern (41) corresponding to the position of the transparent electrode (210); the color filter (5〇) is disposed under the black matrix layer (4〇), It also forms a photoresist block (51) corresponding to the position of the transparent electrode (21 0). The background color and font color of the touch block can be formed by the button pattern (41) of the black matrix layer (40) and the photoresist block (51) of the color filter (5〇), for example, the first figure The digital pattern shown in . Each of the transparent electrodes (21 〇) has a corresponding one of the light-emitting members (1 00). When the finger presses one of the touch blocks, the associated transparent electrode (210) transmits and transmits a signal. To a driving chip, the corresponding light-emitting member (1〇〇) is driven by the driving chip, and since the driving chip only causes the corresponding light-emitting member (1〇0) of the touch block to be bright, only the driver The area covered by the touch block has a light source passing through the black matrix layer (4 〇) and the color filter (50) to display the color, and the remaining illuminating members are closed without the area of other touch blocks. The area displays the color. Please refer to the third embodiment for an exploded view of the second preferred embodiment of the present invention. The difference from the previous embodiment is that each of the illuminating members (100) is a three-primary color LED module. Driving the wafer control and mixing the red, blue and green colors into different colors, so that the bottom surface of the glass substrate (2〇) does not need to be provided with a color filter, only the black matrix layer (40) is required. (4〇) As in the previous embodiment, the transparent electrode (21〇) is formed. The shape and position form a button pattern (41). The third preferred embodiment of the present invention is shown in the fourth and fifth figures. The difference between the first embodiment and the first embodiment is that a first transparent electrode layer (21A) is disposed under the glass substrate (2〇). And a second transparent electrode layer (21 B), the sixth M363641 a transparent electrode (21A) and the second transparent electrode (21 B) are separated by a buffer layer (201), wherein the first transparent electrode layer ( 21A) comprising a plurality of first transparent electrodes (21 0A) 'The second transparent electrode layer (21B) comprises a plurality of second transparent electrodes (210B)' as shown in the fifth figure 'the first transparent electrodes (2A And the second transparent electrode (21 0B) together constitutes a plurality of touch-blocks (22) capable of providing sensing, and the button pattern (41) of the black matrix layer (40) corresponds to the touch block (22) position. In the third embodiment, it is also possible to determine whether or not the color filter (50) is provided by a single white light emitting diode or a two primary color light emitting diode module. In summary, the main purpose of the present invention is to make the transparent electrodes constitute a plurality of illuminating members corresponding to the button pattern area, and the individual illuminating members are controlled to be turned on and off by the driving chip, so that when the finger is pressed against one of the touch blocks, since the driving chip is only The illuminating member corresponding to the touch block is illuminated, so that only the area covered by the touch block can have a light source through to display the color, and the area of the other touch block does not display the color. - Come, the light source feedback mechanism generated by the finger touch, that is, the user can confirm whether the touch position is correct.
