The method (the meaning of the first signal and the second signal) is the same as the touch panel module lion shown in FIG. 3, and therefore the same process as the touch panel module 300 in the operation of the touch panel module 1000 I won't go into details. When the first signal generated by the first optical unit leg has four pulses in a scanning period as shown in FIG. u, it means that there are two pressure-contact objects on the surface panel ι〇ι〇, and the control unit is controlled at this time. The cap enables the second wire and the second wire unit in the first optical unit _, and the first light unit surface is received via a second reflecting unit of the second and third return reflecting units 1〇14, 1〇16 Reflecting the second band of light to generate a second signal, and the second optical unit 1 〇 32 generates a Lu beam at this time, and receives the beam through the first and second reversion reflecting units 1 〇 12, ι 4 Reconstructing the light reflected by the reflecting unit to generate a third signal, wherein the control unit 1040 simultaneously detects the first signal generated by the first optical unit 1030, the second signal, and the third signal generated by the second optical unit 1032. Two pressure contacts on the surface panel 1010 and the position of the two pressure contacts can be calculated. The operation flow of the touch panel module 1000 is only more than the operation flow of the touch panel module 3 shown in FIG. 5, and the third signal generated by the second optical unit 1〇32 is used to simultaneously detect the surface. The steps of the two pressure contacts on the panel 1010, those skilled in the art should be able to simultaneously detect the surface of the surface of the touch panel module 3 after the operation of the touch panel module 3 The step of pressing the contact is added to the flow shown in Fig. 5 (4) = the step is added to the step shown in Fig. 5), the _ fine flow is no longer here = in addition, in the actual _, the second optical unit The level of the salary is: and can be connected to the (four)-, and the second beam of the unit 1 is set to reflect the reflected light beam to generate the third signal. However, in other practical aspects of the invention, The second optical unit 1032 can receive the county reflected by the first, second, third, and third reversion reflection units (4), 1GM, and the brain-return reflection unit by changing the position of the second optical unit working face panel. Generate three signals, these design changes should belong to the Ming Fan . The descriptions of the present invention are merely preferred embodiments of the present invention, and all modifications and modifications made in accordance with the scope of the present invention are within the scope of the present invention.
