FIG. 3A is a schematic view showing the upper electrode plate and the lower electrode plate of the touch region 31A according to an embodiment of the present invention. Here, please refer to FIG. 3 电阻 Resistive type 201224743 The touch panel has a touch area 310, and the touch area 310 has an upper electrode board 320 and a lower electrode board 330. For convenience of explanation, the axial direction of the upper electrode plate 320 is defined as the X-axis direction, and the axial direction of the lower electrode plate 330 is defined as the Y-axis direction. There is a first pair of axial ends XL and XR in the X-axis and a second pair of axial ends YU and YD in the Y-axis. A touch position POS1 is drawn on the touch area 310, and is represented by "+" in FIG. 3A. When the touch position POS1 is touched, its coordinate value is transmitted to the equivalent resistance measurement of the unit to be tested UUTq with respect to the touch position POS1, which is described in detail below.

When the detecting device 2 ι wants to perform the function test of the touch position PQS1, since the actual coordinate value is (χ & Yn), the control unit 120 needs to turn on the line of the output terminal XI of the first series resistor 22A, and will be the second The line of the output of the series resistor 23A is turned on, thereby providing the simulated coordinate value (Χ1, , unit υυτ. So-to, the unit to be tested υυτ (will be the function of the value (XI, Υ5) and output the test result TR, thereby causing The control unit 120 can determine that the function performed by the unit to be tested υυτ is normal according to the test result TR. Similarly, when the detecting device 210 wants to perform the power month test of the touch position p〇S5, the touch position POS5 corresponds to the actual coordinate The value (χη, Ya). The control unit 201224743 needs to turn on the line of the output terminal χ5 of the first series resistor 220, and turn on the line of the output end γι of the second series resistor 23〇, thereby providing a simulated coordinate value ( Χ5,, γι,) is given to the unit to be tested υσΓ.

The value U'' γ')' is such that the coordinate value (χ, γ') is output to the unit to be tested for rain. In this way, the unit to be tested υυτ can be associated with the coordinate value (χ,,Υ,) 12 201224743 The function outputs the test result TR, so that the control unit 52 can determine whether the function performed by the unit UUT to be tested is normal according to the test result TR. This also achieves similar effects to the above embodiments. However, this embodiment differs from the foregoing embodiments in that: Φ Φ control unit 520 can also control some of the switches (eg, relays) in switching unit 54A to provide the operation of the unit UUT to be tested. Operating voltage. In addition, the control unit 520 can also directly transmit commands to the menu το UUT through the input and output unit 55, thereby performing a function test or other control operation of the touch position, and the control unit 52() and the unit UUT to be tested Bidirectional data transfer can be performed by this input output unit 55G. According to the red, the detecting device and the detecting system of the present invention mainly provide electric and type touch position information for the unit (the circuit board) to perform the second type, so that the device can be installed before testing the unit to be tested. The physical = touch panel, and the test does not require artificial pressing, and does not require complicated testing mechanism, so it can save the test cost, and record the test speed and test accuracy of the test π.
