Embodiment Construction

[0014] like figure 1 As shown, it is a schematic diagram of the operating environment of a preferred embodiment of the touch screen testing system of the present invention. The touch screen testing system 100 runs in a touch screen testing device 1 , and the touch screen testing device 1 includes a display 10 and an input device 11 . The input device 11 can be a keyboard, a mouse, and the like. The display 10 is an output device of the touch screen testing device 1 . In other embodiments, the display 10 may have a touch function and an input function of the input device 11 .

[0015] The touch screen testing device 1 has three motion axes, which are respectively located in the X-axis direction, the Y-axis direction, and the Z-axis direction. Hereinafter, the three motion axes are referred to as the X-axis, the Y-axis, and the Z-axis for short. Wherein, a voice coil motor 12 and a pen tip 13 are installed on the Z axis, and driving motors 14 are respectively installed on the...

Abstract

The invention relates to a method for testing a touch screen, which comprises the following steps of: receiving a pre-test parameter and a test parameter, which are set by a user, for testing the touch screen by using a pen point driven by a voice coil motor, wherein the pre-test parameter comprises a coordinate value of an ideal position at which the pen point is needed to arrive when the pen point approaches the touch screen; controlling the voice coil motor to drive the pen point to approach the touch screen to be tested according to the pre-test parameter; reading the coordinate value of an actual position at which the pen point arrives; determining that the pen point contacts the touch screen to be tested when a difference between the coordinate value of the actual position at which the pen point arrives and the coordinate value of the ideal position set by the user is beyond the allowable range; and controlling the voice coil motor to drive the pen point to test the touch screen to be tested according to the test parameter when the pen point contacts the touch screen to be tested. In addition, the invention provides a system for testing the touch screen. By the method and the system, the touch screen can be accurately tested.

Description

technical field [0001] The invention relates to a testing system and method, in particular to a touch screen testing system and method. Background technique [0002] The touch screen has many advantages such as ruggedness, fast response, space saving, and easy communication. Using this technology, our users can operate the computer host as long as they lightly touch the icons or text on the computer display screen with their fingers, so that the human-computer interaction is more straightforward. This technology greatly facilitates those who do not understand computer users. [0003] However, the durability of the touch screen must be tested before leaving the factory, that is, the wear resistance of the touch screen. When the current touch screen scratch testing machine is testing the touch screen, the pen tip of the testing machine may touch the touch screen due to excessive force before performing the scratch test, causing damage to the touch screen, making it difficult...
