Reference may be made to the following embodiments.
Referring to fig. 1, fig. 1 is a flowchart of a method for detecting a panel routing according to an embodiment of the present invention. The method may include:
s101: and acquiring an upper threshold voltage and a lower threshold voltage obtained by detecting the panel wiring voltage by a voltage detection circuit of the driving IC chip.
The implementation main body of the embodiment is panel wiring detection equipment. In the embodiment, the voltage detection circuit of the driving IC chip is used to detect the panel wiring voltage, and the detection process may refer to the conventional step of detecting the panel wiring voltage by using the voltage detection circuit of the driving IC chip. In contrast to the prior art, in this embodiment, by acquiring the upper limit voltage and the lower limit voltage of the panel wiring, a range value within a voltage allowable range can be obtained. In this embodiment, the upper limit voltage and the lower limit voltage of the panel wiring are the specific voltage values at which the panel state is converted, and the panel state is not changed when the panel wiring voltage reaches between the upper limit voltage and the lower limit voltage from above the upper limit voltage of the panel or below the lower limit voltage of the panel. The voltage detection circuit of the driving IC chip in this embodiment may refer to fig. 2, and fig. 2 is a schematic structural diagram of the voltage detection circuit of the driving IC chip according to an embodiment of the present invention. The voltage detection circuit 21 disposed in the driving IC chip 20 is coupled to the panel trace 11 to detect the panel trace 11 of the panel 10.
S102: and determining the value range of the resistance value of the panel wiring according to the upper threshold voltage and the lower threshold voltage based on the hysteresis corresponding relation between the panel wiring voltage and the panel wiring resistance value.

S103: and obtaining the wiring resistance value of the panel.
In this embodiment, the actual resistance value of the panel wiring is obtained, and the embodiment is not limited to a specific manner of obtaining the panel wiring resistance value, so long as the actual wiring resistance value of the current panel can be accurately obtained. The specific timing for acquiring the panel wiring resistance is not limited in this embodiment as well. For example, the step of acquiring the panel wire resistance value may be performed before acquiring the upper and lower threshold voltages of the panel wire voltage, or the step of acquiring the panel wire resistance value may be performed after acquiring the upper and lower threshold voltages of the panel wire voltage.
Further, in order to ensure that the current actual wiring resistance of the panel is obtained, the detection cost is reduced, and the obtaining of the wiring resistance of the panel may include:
Step S11: and acquiring the panel wiring resistance value detected by the voltage detection circuit of the driving IC chip.
It should be noted that, in this embodiment, the voltage detection circuit of the driving IC chip is used to detect the actual resistance value of the panel wire, so that the voltage detection circuit can be adapted to the upper threshold voltage and the lower threshold voltage of the obtained panel wire, and the panel wire detection cost is reduced. The embodiment is not limited to a specific manner of detecting the actual resistance of the panel wiring by the voltage detection circuit of the driving IC chip, as long as the accurate resistance of the panel wiring can be detected.
S104: if the resistance of the panel wiring is in the range of the resistance, determining that the panel wiring is qualified.
In this embodiment, whether the panel is qualified is determined according to the correspondence between the resistance value and the resistance value range. In this embodiment, if the current panel routing resistance is within the resistance value range, it is determined that the current panel is qualified. According to the embodiment, the obtained actual resistance value of the current panel wiring is compared with the value range of the resistance value, the unqualified panel can be effectively removed, the situation that the qualified panel is wrongly brushed due to poor contact, short measurement time and other reasons is avoided, the accuracy of panel wiring detection is improved, and meanwhile whether the resistance value of the panel wiring is in an acceptable range or not can be detected, and the accuracy of panel wiring detection is further improved.
Further, in order to further improve the accuracy of detecting the panel through the panel wiring resistance, after determining the resistance value range of the panel wiring according to the upper threshold voltage and the lower threshold voltage based on the hysteresis correspondence between the panel wiring voltage and the panel wiring resistance value, the method may further include:
step S21: adjusting the resistance value range according to the standard resistance value range to obtain a final resistance value range;
correspondingly, if the resistance of the panel wiring is within the range of the resistance, determining that the panel wiring is qualified may include:
step S22: if the resistance value of the panel wiring is in the final resistance value range, determining that the panel wiring is qualified.
In this embodiment, the standard resistance value range is used to adjust the resistance value range to obtain a final resistance value range, and the final resistance value range and the panel wiring resistance value are used to determine whether the panel is qualified. In this embodiment, the setting value of the standard resistance value range is not limited, and the setting basis of the standard resistance value range is not limited, and may be set by user definition according to an operator or provided by a panel manufacturer. It should be further noted that, in this embodiment, the standard resistance value range is used to adjust the resistance value range, so that flexibility of determining whether the panel wiring is qualified or not by using the resistance value of the panel wiring can be improved, so as to implement an acceptable resistance value range for elastic adjustment.
Further, in order to improve the efficiency of panel routing detection, reference may be made to fig. 3, and fig. 3 is a flowchart of another panel routing detection method provided in an embodiment of the present invention. Before the resistance value range is adjusted according to the standard resistance value range to obtain the final resistance value range, the method can further comprise:
S201: calling a mapping table of the resistance value and the characterization value to obtain a standard characterization value range corresponding to the standard resistance value range and a characterization value range corresponding to the resistance value range;
correspondingly, the adjustment of the resistance value range according to the standard resistance value range to obtain a final resistance value range may include:
S202: adjusting the value range of the representation values according to the value range of the standard representation values to obtain a final value range of the representation values corresponding to the final value range of the resistance values;
If the resistance value of the panel wiring is in the final resistance value range, determining that the panel wiring is qualified comprises the following steps:
S203: if the characterization value corresponding to the panel wiring resistance value is in the final characterization value range, determining that the panel wiring is qualified.
It should be noted that, in this embodiment, by calling the mapping table of the resistance value and the characterization value, the specific resistance value is replaced by the characterization value during the detection processing, and in the process of detecting the panel wiring, the detection of the panel wiring can be realized only by using the characterization value, so that the efficiency of detecting the panel wiring can be improved. In addition, it should be noted that, in the present embodiment, the mapping table of the resistance value and the characterization value should be a table established in advance.
Further, in order to improve the functionality of the panel wiring detection, it may be set that when the resistance value of the panel wiring is greater than the maximum value of the resistance value range, the information of overlarge resistance value of the panel wiring is output;
And outputting information of too small panel wiring resistance when the panel wiring resistance is smaller than the minimum value of the resistance range.
It should be noted that, in this embodiment, when the resistance value of the panel wire is greater than the maximum value of the resistance value and the resistance value of the panel wire is less than the minimum value of the resistance value, prompt information is output, so that a inspector can timely and intuitively obtain the result of the panel wire inspection. In this embodiment, the voice output module and the image output module may be used to output prompt information, so that relevant personnel may obtain prompt information in time.
Further, in order to improve the accuracy of the panel routing detection, the steps of the panel routing detection method may be executed again when the panel routing resistance is greater than the maximum value of the resistance range and the panel routing resistance is less than the minimum value of the resistance range.
It should be noted that, when the panel wiring resistance value simultaneously satisfies a maximum value greater than the resistance value range and a minimum value smaller than the resistance value range, the detection result is obviously incorrect, and the steps of the panel wiring detection method need to be re-executed at this time to obtain an accurate panel detection result. The accuracy of panel wiring detection and the efficiency of panel wiring detection are improved.
