The invention also provides a preferred embodiment, which provides a touch display delay test method of the capacitive touch screen.
Referring to fig. 3, a schematic block diagram of a preferred embodiment of the present invention is described below with reference to fig. 3, wherein the principle of the test method of the preferred embodiment is as follows:
1, the whole test system is divided into three parts, namely a control panel, a screen flash acquisition unit (a light shield and a photosensitive diode) and a touch control execution unit; as shown in fig. 4, a structure of the touch execution unit is shown.
As shown in fig. 4, the touch execution unit includes: the device comprises an electromagnet, an armature, two metal probes and conductive cloth.
2, the terminal PC can supply power to the control board through a USB interface (VCC5V, USB +, USB-, GND), read test data in the MCU on the control board and send a control command to the MCU;
and 3, a control signal DO _1 of the MCU is used for controlling the electromagnet coil to be electrified, the default is low level, namely the electromagnet is not electrified, the metal probe below is in contact with the conductive foam, the two probes are in short circuit, and a DI _2 input signal of the MCU is low level. At this time, the touch screen has an external touch capacitor (the metal probe and the fixed bracket and the corresponding finger capacitor) which is pressed on the touch screen for a long time.
And 4, the MCU controls the DO _1 to output a high level, the electromagnet coil is electrified to generate magnetic force, the metal probes are quickly attracted, when the two probes leave the conductive foam, the finger capacitor attached to the touch screen drops, meanwhile, the two metal probes are opened, the DI _2 signal input of the MCU is the high level, and the MCU detects the rising edge of the DI _2 in an interruption mode, so that the moment of touch failure can be known and recorded as T0. Cell-phone or other equipment are equipped with the test APP, and when the APP detected that the finger electric capacity that long pressed drops, the display screen was become white screen by the black screen, and photosensitive diode detects white screen back, and DI _1 becomes the low level by original high level. The MCU detects the falling edge of DI _1 in an interrupt mode, and once a valid falling edge signal is detected, it proves that the screen has completed displaying from black screen to white screen, and records the time T1. As shown in fig. 5, the photodiode detects a signal in a schematic diagram.
5, T1-T0 is the overall time delay that needs to be tested. Fig. 6 shows a schematic diagram of the time delay analysis. As shown in fig. 6, the difference between the touch failure time T0 and the display update completion time T1, T1, and T0 is the time duration of the delay. The touch failure time T0 is a first time when the touch execution unit receives the second touch signal and leaves the touch screen, and the first touch signal is generated at the first time. The update completion time T1 is a second time when the screen flash collecting unit detects that the screen is bright, and a second touch signal is generated at the second time.
With the preferred embodiment described above, error analysis: the MCU program is simple, and the delay of the MCU can be smaller than 10us by adopting the edge change of DI _1 and DI _2 in an interrupt mode. The display acquisition end adopts a pure semiconductor device, the inversion from black screen to white screen is acquired, the delay is in ns level and can be ignored. Thereby ensuring the precision (<10us) of the acquisition time delay on the whole link.
After the external interrupt signal is generated, the MCU can generally acquire the interrupt signal in at most 2-4 cycles, and for a 51-chip microcomputer with a clock frequency of 12M, the clock cycle is 1/12us, i.e., one cycle is 1us, i.e., at most 4 us. This delay can be made smaller if a higher frequency MCU is used.
Therefore, the preferred embodiment can ensure that the touch event time detected by the controller is the screen triggering time without time delay, improve the testing precision from touch to display time delay, realize full-automatic testing, and improve the working efficiency, the operation consistency and the safety. The damage to the touch screen caused by improper operation due to manual operation is avoided.
