In the present embodiment, in order to improve the accuracy of the voice coil motor 12, the correction compensation operation for the voice coil motor 12 can be repeated. If the difference between the actual output force and the ideal output force is within the allowable error range, the voice coil motor 12 does not need to be compensated. [0017] The receiving module 20 is further configured to receive text input by the user, and establish a font according to the received text. In this embodiment, the user can input text through the input device 11 or directly import text from other external devices. The receiving module 20 is further configured to receive a pre-test parameter and a test parameter of the voice coil motor 12 that is set by the user to drive the pen head 13 to test the touch screen 2. The pre-test parameters include the ideal output force and moving speed when the pen tip 13 is close to the touch screen 2 to be tested, and the coordinate value of the ideal position at which the pen tip 13 reaches. The coordinate value described in the present invention refers to the space coordinate value in the work space of the touch panel test device 1. The ideal output force and moving speed when the pen tip 13 is close to the touch screen 2 to be tested can be determined by the material of the touch screen 2 to be tested. The test parameters include: a range of regions of the X-axis and the Y-axis, that is, a horizontal working range of the pen tip 13, a test mode selected by the user, a pen height of the pen tip 13, and a use of the pen tip 13 when performing a test on the touch screen 2. The size of the force. The test methods include: clicking, writing, drawing, and the like. [0019] The control module 21 is further configured to control the voice coil motor 12 to drive the pen tip 13 to approach the touch screen 2 to be tested according to the pre-test parameter set by the user, and control the voice coil motor 12 to drive the pen tip 13 to be tested according to the test parameter. Measured touch screen 2 099113392 Form number A0101 Page 7 / Total 17 page 0992023613-0 201137696 [0020] The reading module 2 2 is also used when the test mode set by the user is writing, from the created font library Read the text you need. The reading module 22 is also used to read the coordinate value of the actual position reached by the pen tip 13. [0021] The judging module 24 is configured to determine whether the difference between the coordinate value of the actual position reached by the pen tip 13 and the coordinate value of the ideal position set by the user is within an allowable range. In this embodiment, the allowable range may be (-2 0/zm, 20/zm). If the difference between the coordinate value of the actual position reached by the pen tip 13 and the coordinate value of the ideal position set by the user is not within the allowable range, the judging module 24 determines that the pen tip 13 is in contact with the touch screen 2 to be tested. If the difference between the coordinate value of the actual position reached by the pen tip 13 and the ideal position coordinate value set by the user is within the allowable range, the judging module 24 determines that the pen tip 13 does not touch the touch screen 2 to be tested. [0022] As shown in FIG. 3, it is a flowchart of the operation of the preferred embodiment of the touch screen testing method of the present invention. [0023] In step S30, the receiving module 20 receives the ideal output force of the voice coil motor 12 set by the user. [0024] Step S31, the control module 21 inputs the ideal output force to the voice coil motor 12, and controls the voice coil motor 12 to drive the pressure sensor 3 on the Z-axis according to the ideal output force. [0025] Step S32, the reading module 22 reads the actual output force sensed by the pressure sensor 3, and displays the actual output force on the display screen 30 of the pressure sensor 3 and the display 10 . [0026] In step S33, the correction module 23 determines whether the difference between the actual output force and the ideal output force is within an allowable error range. In this embodiment, the allowed 099113392 form number A0101 page 8/17 page 0992023613-0 201137696 The error range is [-10g, l〇g]. If the difference between the actual output force and the ideal output force is not within the allowable error range, the process proceeds to step S34. If the difference between the actual output force and the ideal output force is within the allowable error range, the process proceeds directly to step S35. [0027] Step S34, the correction module 23 calculates the compensation value of the voice coil motor 12 based on the actual output force and the ideal output force, and compensates the voice coil motor 12 by using the compensation value. In the present embodiment, in order to improve the accuracy of the voice coil motor 12, steps S30 to S34 may be repeatedly performed. [0028] Step S35, the receiving module 20 receives the text input by the user, and creates a font according to the received text. In this embodiment, the user can input text through the input device 11 or directly import text from other external devices. The font can be created at any time prior to testing, as before step S30. [0029] Step S36, the receiving module 20 receives the pre-test parameters and test parameters of the touch screen 2 that the user controls the voice coil motor 12 to drive the pen head 1 to test. The pre-test parameters include the ideal output force and the moving speed of the pen tip 13 as it approaches the touch screen 2 to be tested and the coordinate 〇 value of the ideal position reached by the pen tip 13. The ideal output force and moving speed when the pen tip 13 is close to the touch screen 2 to be tested are determined by the material of the touch screen 2 to be tested. The test parameters include: a range of regions of the X-axis and the Y-axis, that is, a horizontal working range of the pen tip 13, a test mode selected by the user, a pen height of the pen tip 13, and a use of the pen tip 13 when performing a test on the touch screen 2. The size of the force. The test methods include: clicking, writing, drawing, and the like. [0030] Step S37, the control module 21 controls the voice coil motor 12 to drive the pen tip 13 to approach the touch screen 2 to be tested according to the pre-test parameters set by the user. 099113392 Form No. A0101 Page 9 of 17 0992023613-0 201137696 [0031] Step S38, the determination module 24 determines whether the difference between the coordinate value of the actual position at which the pen tip 13 arrives and the coordinate value of the ideal position set by the user is allowed. In the range. In the present embodiment, the allowable range is (-20#m, 20//m). If the difference between the coordinate value of the actual position at which the pen tip 13 arrives and the coordinate value of the ideal position set by the user is not within the allowable range, the process proceeds to step S39. If the difference between the coordinate value of the actual position reached by the pen tip 13 and the ideal position coordinate value set by the user is within the allowable range, then the process proceeds to step S40 °. [0032] Step S39, the determination module 24 determines that the pen tip 13 is in contact with The touch screen 2 to be tested is moved to step S41. [0033] Step S40, the determining module 24 determines that the pen tip 13 does not touch the touch screen 2 to be tested, and returns to step S37. [0034] Step S41, the control module 21 controls the voice coil motor 12 to drive the pen head 13 to test the touch screen 2 to be tested according to the test parameters set by the user. If the test mode set by the user is writing, the text is read from the created font, and the control module 21 controls the voice coil motor 12 to drive the pen tip 13 to write the read character on the touch screen 2.
