In view of this, embodiments of the present invention provide a device and a method for testing touch latency, which are used to test a delay time from when a touch screen is clicked to when a device under test of a mobile terminal is turned on. This will be described in detail below.
Referring to fig. 1, fig. 1 is a schematic structural diagram illustrating a touch delay testing apparatus 10 according to an embodiment of the present invention. The touch delay test device 10 includes a control module 101, a driving module 102, a touch input module 103, and a waveform test module 104.

The control module 101 may be, but is not limited to, an integrated circuit chip having signal Processing capability, the control module 101 may be a general-purpose Processor including a Central Processing Unit (CPU), a Network Processor (NP), a voice Processor, a video Processor, etc., and may also be a digital signal Processor, an application specific integrated circuit, a field programmable gate array or other programmable logic device, a discrete gate or transistor logic device, or a discrete hardware component. As an embodiment, the control module 101 may be, but is not limited to, a single chip.
In this embodiment, the driving module 102 is configured to trigger a first signal according to the control instruction, and drive the touch input module 103 to simulate clicking a touch screen of the mobile terminal 20 according to the first signal, where the first signal may be a preset voltage value. After receiving the control instruction sent by the control module 101, the driving module 102 triggers a first signal meeting the requirement of the control instruction, and sends the first signal to the touch input module 103, so that the touch input module 103 simulates clicking the touch screen of the mobile terminal 20. The driving module 102 may be composed of two independent functional modules of a functional module for triggering the first signal and a driving function, or may be a unified module integrating the function for triggering the first signal and the driving function.
In this embodiment, the touch input module 103 is configured to operate the touch screen of the mobile terminal 20 according to the first signal when receiving the first signal, so as to simulate clicking the touch screen of the mobile terminal 20. The touch input module 103 is pre-disposed in an area of the touch screen corresponding to the tested device 201, and the tested device 201 can be started by simulating and clicking the area of the touch screen corresponding to the tested device 201. The area corresponding to the device under test 201 may be a position where an icon corresponding to the device under test 201 is displayed on the touch screen display interface. Different tested elements 201 correspond to different areas in the touch screen. When the touch screen of the mobile terminal 20 is a capacitive screen, the capacitive screen utilizes current induction to change the capacitance value of the corresponding position of the screen to achieve the purpose of simulating clicking of the touch screen, at this time, the touch input module 103 is arranged above the touch screen and contacts with the touch screen, the touch input module 103 can be an electronic finger, and the electronic finger is a foil made of conductive metal. When the touch screen of the mobile terminal 20 is a resistive screen, the resistive screen achieves the purpose of simulating the click of the touch screen by changing the pressure of the corresponding position on the touch screen, at this time, the touch input module 103 may be disposed above the touch screen and in contact with the touch screen, or disposed above the touch screen and at a preset distance from the touch screen, the touch input module 103 may be an electronic pen, and the driving module 102 needs to drive the electronic pen to generate a pressure to the touch screen, so that the effect same as that of a real finger of a person clicking the touch screen is achieved.

The test parameter may be a default value pre-stored in the control module 101, or may be a value set by the user through the input module 105, where if the user does not set through the input module 105, the default value is used as the standard, and if the user sets through the input module 105, the value set by the user is used as the standard. For example, the default values are: the frequency is 12MHz, the amplitude is 5, the preset voltage threshold is 1.5, and when the user is not set, the test parameters in the control command are as follows: the frequency is 12MHz, the amplitude is 5, and the preset voltage threshold is 1.5. When the test parameters set by the user are as follows: the frequency is 15MHz, the amplitude is 8, the preset voltage threshold is 2, and the test parameters in the control command are as follows: the frequency is 15MHz, the amplitude is 8, and the preset voltage threshold is 2.
In step S2, the driving module 102 triggers a first signal according to the control instruction, and drives the touch input module 103 to simulate clicking an area corresponding to the detected component in the touch screen of the mobile terminal 20 according to the first signal.

As an embodiment, the first signal may be a preset voltage value, and the driving module 102 may periodically generate the preset voltage value to continuously perform simulated clicking on the touch screen of the mobile terminal 20, and finally obtain a plurality of touch delay test data. The generation period of the first signal may be determined by the frequency in the control command, for example, the frequency is 50Hz, and the period is 0.02 seconds, i.e., a preset voltage value is generated every 0.02 seconds.
In this embodiment, as an implementation manner, the driving module 102 includes a signal generator 1021 and a driving circuit 1022, the signal generator 1021 receives a control command sent by the control module 101, and triggers a first signal according to the control command, the driving circuit 1022 drives the touch input module 103 to simulate clicking on the touch screen according to the first signal, and step S2 includes sub-step S21 and sub-step S22.

As a specific embodiment, the second signal may be a voltage value greater than a preset threshold, and when the waveform test module 104 captures the second signal, it determines whether the second signal is greater than the preset threshold, and if so, it determines that the device 201 is activated and operated, and records the generation time of the second signal. In this embodiment, the preset threshold may be set by the input module 105, for example, if the preset threshold is 3, and the voltage value of the current second signal is 2.5, the waveform testing module 104 may determine that the second signal does not excite the device under test 201 to enter the working state, and may not record the time when the second signal occurs, and if the voltage value of the current second signal is 3.5, the waveform testing module 104 may determine that the second signal excites the device under test 201 to enter the working state, and the time when the second signal occurs is the second time.
