[0049] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0050] like Figure 1As shown in FIG. 1 , the structure of the embedded touch device is, from bottom to top, a backlight layer, a lower polarizer layer, an array glass layer, a liquid crystal layer, a color filter glass layer, and an upper polarizer layer, wherein the touch electrodes and the display electrodes are located on the upper side of the array glass layer. Figure 2 As shown, the touch electrodes are arranged in a two-dimensional array, and there are tiny gaps between each touch electrode. Each touch electrode is individually led out to the controller through a metal wire to realize signal collection and processing.

[0051] Due to the limitation of manufacturing process, there may be abnormal connection between touch electrode and metal wire (such as Figure 3 If the touch electrode is abnormally connected to the metal wire, the touch electrode will be out of the control of the controller, causing the area to lose touch response capability. The current detection scheme can only judge the detection result of the touch device as a whole, but cannot locate the specific physical location of the faulty touch electrode. Since the side length of each touch electrode is only about 4 to 5 mm, it is difficult to identify the faulty touch electrode. Therefore, in order to detect such faulty touch electrodes in a timely manner, the present disclosure proposes the following technical solutions.

[0052] According to a first aspect of an embodiment of the present disclosure, a touch control component detection device is provided. Figure 4 As shown, the detection device includes multiple detection units, and the detection units correspond one-to-one to the touch electrodes in the touch component; the detection unit is used to obtain a detection voltage based on the excitation signal of the touch electrode; the detection voltage is compared with a reference voltage to obtain a comparison result; based on the comparison result, it is determined whether the detection unit is an abnormal detection unit; if so, it is characterized that the touch electrode corresponding to the abnormal detection unit is an abnormal touch electrode.

[0053] Specifically, the touch component detection device includes a plurality of detection units, and the installation position of each detection unit in the detection device is the same as the installation position of the touch electrode in the touch component, and one detection unit corresponds to one touch electrode. Figure 4 As shown, during the detection process, the detection device is placed directly above the touch control component to ensure that the detection unit is located directly above the corresponding touch control electrode.

[0054] During the operation of the touch component, each touch electrode will periodically send an excitation signal Sx. When each detection unit in the detection device is in operation, it will obtain a detection voltage based on the excitation signal Sx sent by its corresponding touch electrode. Then the detection voltage is compared with the preset reference voltage to obtain a comparison result. According to the comparison result, the detection device can determine whether the current detection unit is in an abnormal state. Due to the one-to-one correspondence between the detection unit and the touch electrode, when the detection unit is in an abnormal state, it can be directly determined that the corresponding touch electrode is in an abnormal state, thereby accurately detecting the abnormal touch electrode.

[0055] In the touch component detection device of this embodiment, there is a one-to-one correspondence between the detection unit and the touch electrode, and the detection device can directly and accurately locate the specific touch electrode with a problem, saving the tedious process of manual one-by-one troubleshooting, greatly improving the accuracy and efficiency of touch electrode fault location, and providing great convenience for subsequent maintenance work.

[0056] In one embodiment of the present disclosure, Figure 5 As shown, the detection unit includes a detection electrode, which is arranged on the lower side of the substrate and is used to determine the electric field change between the touch electrode and the detection electrode based on the excitation signal of the touch electrode; and obtain the detection voltage based on the electric field change.

[0057] The characteristic capacitance Ct is formed between the touch electrode and the detection electrode due to the electric field. When the touch electrode sends an excitation signal, it can periodically charge the characteristic capacitance Ct, thereby causing the electric field to change. This electric field change is captured by the detection electrode and converted into a measurable voltage signal, namely the detection voltage.

[0058] In one embodiment of the present disclosure, Figure 5 As shown, the detection unit also includes a comparison module, which is arranged on the upper side of the substrate, and is used to determine that the detection unit is a normal detection unit if the comparison result is that the detection voltage is greater than the reference voltage; if the comparison result is that the detection voltage is not greater than the reference voltage, determine that the detection unit is an abnormal detection unit.

[0059] Specifically, the comparison module compares the detection voltage with a preset reference voltage to determine the magnitude relationship between the detection voltage and the reference voltage. If the detection voltage is greater than the reference voltage, it means that the detected electric field changes significantly and the touch electrode sends the excitation signal normally, so that its corresponding detection module behaves as a normal detection unit. If the detection voltage is not greater than the reference voltage, it means that the touch electrode may be damaged or poorly connected and fails to send the excitation signal successfully, so that its corresponding detection module behaves as an abnormal detection unit.

[0060] In one embodiment of the present disclosure, the comparison module includes a display module, which is arranged on the upper side of the substrate, and is used to determine that the display module is in a first display state if the comparison result is that the detection voltage is greater than the reference voltage, and the first display state indicates that the detection unit is a normal detection unit; if the comparison result is that the detection voltage is not greater than the reference voltage, the display module is determined to be in a second display state, and the second display state indicates that the detection unit is an abnormal detection unit.

[0061] In order to observe the comparison result more intuitively, the comparison result is displayed by the display module in this embodiment. Specifically, the comparison result from the comparison module is received, and if the comparison result is that the detection voltage is greater than the reference voltage, the display module is triggered to the first display state. The first display state can be characterized by lighting an indicator light (such as a green LED), displaying a specific icon or text, etc. to indicate that the detection unit is in a normal state, that is, the touch electrode corresponding to the detection unit can work normally. On the contrary, if the comparison result is that the detection voltage is not greater than the reference voltage, the display module is triggered to the second display state. The second display state can be characterized by turning off the indicator light, displaying an error code, or sounding an alarm, etc. to indicate that the detection unit is in an abnormal state, that is, the touch electrode corresponding to the detection unit is faulty.

[0062] In this embodiment, through the cooperation of the comparison module and the display module, the detection unit can realize real-time monitoring and feedback of the state of the touch component, and provide the user with more intuitive detection results through different display states of the display module.

[0063] In one embodiment of the present disclosure, the comparison module is a voltage comparator, and the display module includes a switch tube and an indicator light. Figure 6 As shown, the device includes a low-pass filter LF, a voltage comparator, a transistor Q, an indicator light LED, and three resistors R1, R2 and R3 for circuit protection.

[0064] During the operation cycle of the touch control component, each touch control electrode regularly emits an excitation signal Sx, which is transmitted through the characteristic capacitor Ct, thereby periodically charging the characteristic capacitor Ct. The detection unit also includes a voltage comparator U1, whose negative input terminal is connected to a fixed reference voltage Vref as a comparison reference, and whose positive terminal Vin receives a sample of the characteristic capacitor from the detection unit.

[0065] When the touch component is in normal operation, the excitation signal Sx emitted by the touch electrode is collected by the detection unit, and after filtering out high-frequency noise through the low-pass filter LF, it enters the voltage comparator U1 as the positive input signal Vin. At this time, Vin is greater than Vref, which triggers the indicator LED to light up. This intuitively feeds back to the user or system that the touch electrode corresponding to the detection unit is in normal working condition.

[0066] On the contrary, Figure 7 As shown, if the touch electrode is abnormal, the detection unit will not be able to effectively collect the excitation signal Sx of the touch electrode, and the positive input terminal Vin of the voltage comparator U1 will have no effective signal input, and its voltage value will drop below Vref, thereby triggering the indicator light LED to go out, indicating that the touch electrode corresponding to the detection unit is in an abnormal state.

[0067] The device adopts a one-to-one physical mapping strategy between the detection unit and the touch unit, which can quickly and accurately locate the position of the touch electrode where the abnormality occurs, greatly improving the efficiency of fault detection.

[0068] Figure 8 A schematic diagram of the implementation process of a touch component detection method according to an embodiment of the present disclosure is shown. Figure 8 As shown, according to the second aspect of the embodiment of the present disclosure, a touch component detection method is provided, and the detection method is applied to the touch component detection device described in the above embodiment. The method includes:

[0069] Step 101, obtaining a detection voltage based on an excitation signal of the touch electrode;

[0070] Step 102, comparing the detection voltage with a reference voltage to obtain a comparison result;

[0071] Step 103: determining whether the detection unit is an abnormal detection unit according to the comparison result; if so, indicating that the touch electrode corresponding to the abnormal detection unit is an abnormal touch electrode.

[0072] The specific implementation of the detection method can refer to the above discussion on the detection device, which will not be repeated here.

[0073] In one embodiment of the present disclosure, the detection unit includes a detection electrode; and obtaining the detection voltage based on the excitation signal of the touch electrode includes: determining the electric field change between the touch electrode and the detection electrode based on the excitation signal of the touch electrode; and obtaining the detection voltage based on the electric field change.

[0075] In one embodiment of the present disclosure, the detection unit also includes a display module; if the comparison result is that the detection voltage is greater than the reference voltage, determining that the detection unit is a normal detection unit includes: if the comparison result is that the detection voltage is greater than the reference voltage, determining that the display module is in a first display state, and the first display state indicates that the detection unit is a normal detection unit; if the comparison result is that the detection voltage is not greater than the reference voltage, determining that the detection unit is an abnormal detection unit includes: if the comparison result is that the detection voltage is not greater than the reference voltage, determining that the display module is in a second display state, and the second display state indicates that the detection unit is an abnormal detection unit.
