The present disclosure relates generally to a touch testing system and the fixture thereof, and particularly to a multi-touch testing system and the fixture thereof.
In the history of the development of electronic equipment, the emergence of the input interfaces such as keyboards, mice, and touch pads solves the problem of input control. Nonetheless, these input interfaces occupy substantial spaces. For example, the keyboard occupies a half of the volume of a notebook computer or a cell phone. If the space for keyboards can be saved, the portability of products can be certainly improved. The most feasible method is to operate on the panel directly through touch controls. Touch panels surely can replace most functions of keyboards and mice; they also provide users with more intuitive and convenient operating experience. By replacing the keyboards with larger panels, lighter, thinner, and more fashionable designs can be further delivered. In addition, thanks to the completely solid-state panel technology, it is not necessary to worry about the failure problem of mechanical components such as keyboards or wheelers.
Technically, touch panels can be categorized into resistive, capacitive, infrared, surface acoustic wave, electromagnetic, and optical touch panels. By considering endurance, costs, response speed, and convenience, resistive and capacitive touch panels has become the mainstream in the market.
Recently, owing to their considerate touch interfaces, smartphones are favorable for many people. The emergence of multi-touch functions even results in new revolution in user interface. Users can use multi-touch electronic products more intuitively.
The single-touch testing fixture according to the prior art uses an actuator, such as a motor or an oil cylinder, to drive a test head for performing single-touch testing. If the testing method is used for testing a multi-touch panel, multiple actuators are required for driving the corresponding test heads for performing multi-touch testing. Because the test head are not connected to each other and are driven by different actuators, the pressure of each test head on the panel is not uniform with that of any other. Besides, the structure of the overall testing fixture is complicated; it has larger volume and occupies large space.
Accordingly, the present disclosure provides a multi-touch testing system and the fixture thereof. A plurality of test heads of the multi-touch testing system and the fixture thereof are disposed on a movable frame. Then at least a driving module is used for driving the movable frame, which drives the plurality of test heads simultaneously. The pressure of each of the plurality of test heads on the panel is identical to that of any other. Thereby, the testing fixture is simplified.
An objective of the present disclosure is to provide a multi-touch testing system and the fixture thereof. The multi-touch testing fixture allows multiple test heads to press on a device under test simultaneously for performing multi-touch testing.
Another objective of the present disclosure is to provide a multi-touch testing system and the fixture thereof. The multi-touch testing fixture allows the pressure of each test head on the device under test to be identical to that of any other. In addition, the structure of the multi-touch testing fixture is simple.

According to the prior art, when the single-touch testing fixture is adopted for performing multi-touch testing on a panel, the pressure of each test head on the panel is difficult to be kept identical to that of any other. Moreover, the structure of the testing fixture becomes complicated.
Next, the step S12 is executed. The monitoring device 12 activates the multi-touch testing fixture 10 and enabling the multi-touch testing fixture 10 to perform multi-touch testing on the device under test 2. Then, the step S14 is executed. The device under test 2 generates at least a signal and transmits the signal to the monitoring device 12. Finally, the step S16 is executed. The monitoring device 12 produces a testing result according the signal generated by the device under test 2 and judges if the device under test 2 passes the test according to the testing result. The criterion of judging if the device under test 2 passes the test is whether the device under test 2 shows the multi-touch function after multiple presses without damages in the device under test 2. If so, it means that the device under test 2 has excellent pressure tolerance. If the monitoring device 12 judges that the device under test 2 fails to pass the test, the steps S12 to S16 are repeated for re-assuring if the testing result is correct. As the monitoring device 12 judges that the device under test 2 passes the test, the multi-touch test stops.
