In the prior art, the display panel detection process comprises two types, namely optical detection and electrical detection; the defect of the display panel is detected optically, only a small part of defects can be recorded due to the limited number of pictures taken, and the specific position of the defect in the display panel can be reported by electrical detection, but sometimes the defect is smaller or cannot be positioned due to the fact that the defect is close to the edge, so that the defect leaks to subsequent manufacture and the product is scrapped.
In order to solve the above problem, the present invention provides a method for detecting a display panel, as shown in fig. 1, which is a schematic flow chart of an embodiment of the method for detecting a display panel provided by the present invention, and the method for detecting a display panel includes the following steps:

In the embodiment of the present invention, the display panel may be optically detected for multiple times or/and electrically detected for multiple times, so as to improve the accuracy of the optical detection and the electrical detection of the display panel and avoid the leakage of defects, and therefore, the optically detecting the display panel in step S11 may include: carrying out first optical detection on the display panel to obtain first optical detection data; and carrying out second optical detection on the display panel to obtain second optical detection data. At this time, the optical detection data includes first optical detection data and second optical detection data.

For the specific operations of the optical detection and the electrical detection of the display panel, reference may be made to the prior art, which is not described herein in detail.
In some embodiments of the present invention, since it is necessary to determine a specific location of a defect in a display panel, it is necessary to determine whether optical detection and electrical detection of the display panel record location information of the defect in the display panel, and therefore before the merging the optical detection data and the electrical detection data according to a preset condition to generate panel detection data, the method further includes:
judging whether the electrical detection data has identification data or not;
if the electrical detection data contains identification data, determining that the display panel has defects;
the merging the optical detection data and the electrical detection data according to a preset condition to generate panel detection data includes:
and when the display panel has defects, merging the optical detection data and the electrical detection data to generate panel detection data.

(1) And combining the optical detection data and the electrical detection data to obtain panel detection data.
Specifically, in the embodiment of the present invention, the electrical property detection data includes first electrical property detection data and second electrical property detection data, the first electrical property detection data includes first identification data, and the second electrical property detection data includes second identification data. Determining whether the electrical detection data includes the identification data includes determining whether the first electrical detection data includes the first identification data, or determining whether the second electrical detection data includes the second identification data. If the first electrical detection data contains the first identification data or the second identification data or both the first identification data and the second identification data contain identification data, it is indicated that the display panel has defects and the positions of the defects cannot be located.
And if the display panel has defects, merging the optical detection data and the electrical detection data according to a preset condition to generate panel detection data.
Specifically, in some embodiments of the present invention, the determining whether the first electrical detection Data includes the first identification Data is to determine whether Data =1 exists in the first electrical detection Data, in a normal case, the defect coordinate should be greater than 1, and if the defect coordinate is equal to 1, it indicates that the defect of the display panel is not accurately located. Or judging whether a Gate =1 exists in the second electrical detection document, wherein in a normal condition, the defect coordinate should be greater than 1, and if the defect coordinate is equal to 1, the defect of the display panel is not accurately positioned.
If Data =1 exists in the first electrical detection Data or a Gate =1 exists in the second electrical detection Data, or Data =1 exists in the first electrical detection Data and a Gate =1 exists in the second electrical detection Data, the first electrical detection Data and the second electrical detection Data are combined to generate electrical detection Data.
And simultaneously combining the first optical detection data and the second optical detection data to generate optical detection data. At this time, the electrical detection data and the optical detection data are combined to obtain panel detection data.
It should be noted that after the optical detection data and the electrical detection data are generated, the data are both uploaded to a preset data analysis system, and in the data analysis system, whether the electrical detection data have identification data or not is judged, and the optical detection data and the electrical detection data are merged.
(2) And combining the first optical detection data and the first electrical detection data to obtain first panel detection data, combining the second optical detection data and the second electrical detection data to obtain second panel detection data, and combining the second panel detection data and the second panel detection data to obtain panel detection data.
As shown in fig. 2, a schematic flow chart of another embodiment of the present invention is shown, in which the merging the optical detection data and the electrical detection data according to a preset condition to generate panel detection data includes:
s21, merging the first optical detection data and the first electrical detection data to generate first panel detection data.
And S22, merging the second optical detection data and the second electrical detection data to generate second panel detection data.
And S23, merging the first panel detection data and the second panel detection data to generate the panel detection data.
Specifically, in the above embodiment, the step S21 of merging the first optical detection data and the first electrical detection data to generate the first panel detection data is:
when a piece of glass carries out first electrical detection to generate first electrical detection data, the data analysis system reads that Gate =1 appears in the first electrical detection data, which indicates that the electrical defect position of the display panel cannot be accurately positioned, at the moment, the data analysis system reads the first optical detection data obtained by the first optical detection, combines all defect coordinates within +/-2 of scanning line coordinates in the same display panel in the first optical detection data into the first electrical detection data, and finally regenerates and stores the first panel detection data again according to the time point of completion of combination.
Further, step S22 is to combine the second optical detection data and the second electrical detection data, and generate second panel detection data as follows:
when a piece of glass is subjected to second electrical detection to generate second electrical detection Data, the Data analysis system reads that Data =1 appears in the second electrical detection Data, which indicates that the electrical defect position of the display panel cannot be accurately positioned, at the moment, the Data analysis system reads the second optical detection Data obtained by the second optical detection, combines all defect coordinates within +/-2 Data line coordinates of the same display panel in the second optical detection Data into the second electrical detection Data, and finally regenerates and stores the second panel detection Data according to the time point of completion of combination.
And at the moment, combining the first panel detection data and the second panel detection data to obtain panel detection data. Then the data analysis system reads the panel detection data, and the machine repairs the display panel according to the panel detection data, so that the display panel with defects is prevented from being missed to the subsequent processing.
(3) And merging the optical detection data and the first electrical detection data to obtain third panel detection data, and merging the third panel detection data and the second electrical detection data to obtain panel detection data.
As shown in fig. 3, a schematic flow chart of another embodiment of the present invention is shown, in which the merging the optical detection data and the electrical detection data according to a preset condition to generate panel detection data includes:
and S31, merging the first optical detection data and the second optical detection data to generate the optical detection data.
And S32, combining the optical detection data and the first electrical detection data to generate third panel detection data.

s41, judging whether the first electrical property detection data has first identification data.
And S42, if the first electrical detection data contains first identification data and the first position in the display panel is determined to be defective, merging the optical detection data and the first electrical detection data to generate third panel detection data.
And S43, if the optical detection data and the second electrical detection data do not exist, generating the panel detection data according to the optical detection data and the second electrical detection data.
Specifically, after the first electrical detection is completed, first electrical detection data is generated, and the data analysis system analyzes the first electrical detection data to determine whether first identification data exists in the first electrical detection data. And if the first identification data exists in the first electrical detection data, it is indicated that the Gate layer of the display panel has defects when the display panel is electrically detected, and the positions of the defects are not accurately positioned.
Specifically, the first identification Data may be Data =1. That is, if Data =1 appears in the first electrical detection Data, the electrical detection of the display panel detects that the display panel has a defect, and the electrical detection does not accurately position the defect position.
At this time, the optical detection data and the first electrical detection data are combined to generate third panel detection data.
If the first electrical detection data does not have the first identification data, it indicates that the Gate layer in the display panel has no defect or the defect is accurately positioned, and if the defect is accurately positioned, the repairing machine can directly read the first electrical detection data to repair the display panel, so as to prevent the display panel with the defect from being missed to the subsequent manufacturing process.
In another embodiment of the present invention, as shown in fig. 5, which is a schematic flow chart of an embodiment of step S43 provided in the present invention, the step S43 of generating the panel inspection data according to the optical inspection data and the second electrical inspection data may include:
and S51, judging whether second identification data exist in the second electrical property detection data.
And S52, if second identification data exist in the second electrical detection data, merging the optical detection data and the second electrical detection data to generate the panel detection data.
And S53, if the optical detection data do not exist, using the optical detection data as the panel detection data.
Specifically, the Data analysis system determines whether second identification Data exists in the second electrical detection Data, and if the second identification Data exists in the second electrical detection Data, it indicates that the Data layer of the display panel has a defect in the second electrical detection Data, and the position of the defect is not accurately positioned.
If the second electrical detection Data does not have the second identification Data, it indicates that the Data layer in the display panel has no defect or the defect has been accurately positioned, and if the defect has been accurately positioned, the repairing machine can directly read the second electrical detection Data to repair the display panel, thereby avoiding the display panel with the defect from being leaked to the subsequent manufacturing process.
Specifically, the second identification data may be Gate =1, that is, if Gate =1 exists in the second electrical detection number, it is obvious that a defect exists in the panel, and the position of the defect cannot be specifically located.
At this time, the optical detection document obtained by optically detecting the display panel is the panel detection data.
In other embodiments of the present invention, after the combining the optical inspection data and the first electrical inspection data to generate third panel inspection data, the method may further include:

and if the third panel detection data does not exist, taking the third panel detection data as the panel detection data.
Specifically, the data analysis system may determine whether the second identification data exists in the second electrical detection data, that is, the data analysis system may determine whether a Gate =1 exists in the second electrical detection data, and if the second identification data exists, it indicates that a defect exists in a Date layer of the display panel and a position of the defect cannot be accurately located, and at this time, the third panel detection data and the second electrical detection data are merged to generate the panel detection data. The repairing machine repairs the display panel according to the panel detection data, and the display panel with the defects is prevented from being placed in the subsequent processing procedure in a missing mode.
If the second electrical detection data does not have the second identification data, that is, the Gate =1 does not exist, it indicates that there is no defect in the Date layer of the display panel or the defect can be accurately located, at this time, the repairing machine can directly repair the display panel according to the second electrical detection data, and the third panel detection data is used as the panel detection data.
