When the user's finger or other member touches the transparent protective layer 12 of the touch screen 10, an instantaneous capacitance is generated and the control module 19 detects a change in current so that the touched portion is touched. The coordinates of the signal are determined, and a corresponding command signal is generated and transmitted to the terminal equipment such as a computer.

1 and 3, in the present embodiment, the transparent substrate 30 is made of a transparent material such as glass or resin, and the whole exhibits an arc-shaped structure, the center portion of which is slightly ohm wide. Entered. The transparent substrate 30 has an upper surface 32 and a lower surface 33. The upper surface 32 of the transparent substrate 30 is attached to a surface remote from the transparent protective layer 12 of the touch screen 10.

The upper surface 32 of the transparent substrate 30 is provided with a plurality of key markers 34 and a driving circuit 36. In the present embodiment, the key mark 34 is formed by spraying, painting or printing a transparent electroluminescent material. The key marker 34 may be designed according to demand, such as English alphabet, Chinese alphabet, or Japanese, and the shape and arrangement of the key marker 34 may be designed according to demand. The information of the key marker 34 (for example, the coordinate range information of the K key and the corresponding command information) is stored in advance in the control module 19 of the touch screen 10, and such information is stored at the touched position. Respectively. The drive circuit 36 is provided around the key mark portion 34 of the transparent substrate 30 by applying a transparent conductive material. The drive circuit 36 is electrically connected to the key marker 34 and the control module 19 through electrical wiring. The driving circuit 36 controls the light emission or non-light emission of the key marking unit 34. That is, when the driving circuit 36 is energized by the control of the control module 19, the key marking part 34 emits light and is expressed through the touch screen 10. If the furnace 36 is not energized, the key marker 34 does not emit light.

One side of the lower surface 33 of the transparent substrate 30 is provided with a transparent support 38 having the same length as that of the transparent substrate and having an inverted triangle shape.
