Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention provides a kind of array base palte detection method, as shown in Figure 2, can comprise:
S101, as shown in Figure 3, can be connected a line the first grid line 100 at least with the first detection line 11; At least one first signal Transmit-Receive Unit 200 is set on the first grid line 100, to send or to receive detection signal.
S102, general at least a line the second grid line 101 are connected with the second detection line 12; Or, be connected with the second detection line 12 with the first detection line 11; At least one secondary signal Transmit-Receive Unit 201 is set on the second grid line 101, to send or to receive detection signal.
It should be noted that, in said method, preferably the first grid line 100 and the second grid line 101 intervals can be arranged, as shown in Figure 3,2nd, the first grid line 100 of 4,6,8 even number lines is connected with the first detection line 11, and the second grid line 101 of the the 1st, 3,5,7 odd-numbered lines is connected with the second detection line 12.So, can make the wire structures of testing circuit neat, succinct.Certainly, those skilled in the art, also can be according to actual needs, the connected mode of the grid line to each row and the first detection line 11 and the second detection line 12 is adjusted, for example, the grid line of the 1st, 2,3 row can be connected with the first detection line 11, the grid line of the 4th, 5,6 row is connected with the second detection line 12, at this moment the grid line of the 1st, 2,3 row is that the grid line of the first grid line 100, the 4,5,6 row is the second grid line 101.Other connected mode is given an example no longer one by one at this, but all should belong to protection scope of the present invention.
It should be noted that, above-mentioned detection signal, for detection of the on off operating mode of the first grid line 100 or the second grid line 101.First signal Transmit-Receive Unit 200 and secondary signal Transmit-Receive Unit 201 can receive above-mentioned detection signal, can receive again this detection signal.

Again for example, for the 7th row the second grid line 101, one end of this second grid line 101 is connected with the first detection line 11, and the other end is connected with the second detection line 12 simultaneously.And eighth row first grid line 100 adjacent with the 7th row the second grid line 101 is only connected the first detection line 11.At this moment, can a secondary signal Transmit-Receive Unit 201 be set respectively at the two ends of the 7th row the second grid line 101; Near one end of the second detection line 12, a first signal Transmit-Receive Unit 200 is set at eighth row the first grid line 100.So, in the time that on the second grid line 101, the secondary signal Transmit-Receive Unit 201 near first detection line 11 one end sends detection signal, if the 7th row the second grid line 101 and eighth row the first grid line 100 are all in conducting state, on the 7th row the second grid line 101, on the secondary signal Transmit-Receive Unit 201 of close second detection line 12 one end and eighth row the first grid line 100, the first signal Transmit-Receive Unit 200 of one end of close the second detection line 12 all can be subject to above-mentioned detection signal.If the secondary signal Transmit-Receive Unit 201 near second detection line 12 one end on the 7th row the second grid line 101 fails to be subject to above-mentioned detection signal, illustrate that the 7th row the second grid line 101 is in off state; If the first signal Transmit-Receive Unit 200 of one end of close the second detection line 12 fails to be subject to above-mentioned detection signal on eighth row the first grid line 100, illustrate that this eighth row first grid line 100 is in off state.The break-make of other row grid line detects and can, with reference to said method, again give an example no longer one by one.
It should be noted that; above-mentioned is take the first grid line 100 as even number line grid line; the second grid line 101 for odd-numbered line grid line be the explanation that example is carried out; when the first grid line 100 is odd-numbered line grid line; when the second grid line 101 is even number line grid line; or detection method when from the first grid line 100 of other type of the different generations of the first detection line 11 and the second detection line 12 connected modes and the second grid line 101 is the same, does not repeat them here, but all should belong to protection scope of the present invention.
The embodiment of the present invention provides a kind of array base palte detection method, and the method comprises: the first grid line is connected with the first detection line, and the second grid line is connected with the second detection line; Or, be connected with the second detection line with the first detection line; At least one first signal Transmit-Receive Unit is set on the first grid line, at least one secondary signal Transmit-Receive Unit is set on the second grid line; Send respectively or receive the detection signal for detection of the first grid line or the second grid line.So, can avoid two adjacent grid lines to be connected with the first detection line and the second detection line time simultaneously, test signal can be by being received by the signal receiver on grid line to be measured after the grid line adjacent with grid line to be detected, and cause the phenomenon that the off state of grid line to be measured cannot detect to produce, thereby can detect the break-make situation of grid line to be measured exactly.
Further, as shown in Figure 4, in the time that the first grid line 100 is connected with the first detection line 11; The method that first signal Transmit-Receive Unit 200 is set on the first grid line 100 can also comprise:
First signal is set in one end of the first grid line 100 and sends subelement 2001, for sending detection signal to the first grid line 100, the other end arranges first signal and receives subelement 2002, for receiving above-mentioned detection signal.
When the second grid line 101 is connected with the second detection line 12; The method that secondary signal Transmit-Receive Unit 201 is set on the second grid line 101 can also comprise:
Secondary signal is set in one end of the second grid line 101 and sends subelement 2011, for sending detection signal to described the second grid line 101, the other end arranges secondary signal and receives subelement 2012, for receiving detection signal.
Wherein, above-mentioned connected mode can be, all the first grid lines 100 are only connected with the first detection line 11, and the second grid line 101 is only connected with the second detection line 12.This method of testing is concrete, and as shown in Figure 4, the first grid line 100(is even number line the 2nd, 8 row grid lines for example) be connected with the first detection line 11; The second grid line 101(is odd-numbered line the 1st, 7 row grid lines for example) be connected with the second detection line 12.In the time that first signal transmission subelement 2001 sends detection signal to the first grid line 100, if receiving subelement 2002, first signal receives above-mentioned detection signal, illustrate that the first grid line 100 is in conducting state; If first signal receives subelement 2002 and fails to receive above-mentioned detection signal, illustrate that the first grid line 100 is in off state.Detection case for the second grid line 101 is the same.So, because the first grid line 100 connects different detection lines from the second grid line 101, therefore can avoid in the time that the first grid line 100 or the second grid line 101 connect the first detection line 11 and the second detection line 12 simultaneously, because test signal is received by the signal receiver on grid line to be measured after by the grid line adjacent with grid line to be detected, and cause the phenomenon that the off state of grid line to be measured cannot detect to produce, thereby can detect the break-make situation of grid line to be measured exactly.
It should be noted that; below be all take the first grid line 100 as even number line grid line, the explanation carried out as odd-numbered line grid line as example of the second grid line 101; when the first grid line 100 is odd-numbered line grid line; when the second grid line 101 is even number line grid line; or testing process when from the first grid line 100 of other type of the different generations of the first detection line 11 and the second detection line 12 connected modes and the second grid line 101 in like manner can obtain; here repeat no more, but all should belong to protection scope of the present invention.
Further, as shown in Figure 5, when the first grid line 100 is connected with the first detection line 11; First signal is set in one end of the first grid line 100 and sends subelement 2001, the other end arranges first signal and receives subelement 2002; When the second grid line 101 is connected with the second detection line 12 with the first detection line 11; The method that secondary signal Transmit-Receive Unit 201 is set on the second grid line 101 can also comprise:
Secondary signal is set on the second grid line 101 and receives subelement 2012.
Concrete, as shown in Figure 5, the first grid line 100(is even number line the 2nd, 8 row grid lines for example) be connected with the first detection line 11; The second grid line 101(is odd-numbered line the 1st, 7 row grid lines for example) be connected with the second detection line 12 with the first detection line 11.In the time that the first signal transmission subelement 2001 on the first grid line 100 sends detection signal, because second grid line 101 adjacent with this first grid line 100 is connected with the second detection line 12 with the first detection line 11 simultaneously, therefore this detection signal can be divided into two parts, a part is sent to the first grid line 100, and another part is sent to the second grid line 101 by the first detection line 11.Therefore, can receive above-mentioned detection signal if the first signal on the first grid line 100 receives subelement 2002, illustrate that this first grid line 100 is in conducting state; If the first signal on the first grid line 100 receives subelement 2002 and fails to receive above-mentioned detection signal, illustrate that this first grid line 100 is in off-state.In like manner, can receive above-mentioned detection signal if be arranged at the second grid line 101 near the secondary signal reception subelement 2012 of the second detection line 12 1 sides, illustrate that this second grid line 101 is in conducting state; Fail to receive above-mentioned detection signal if secondary signal receives subelement 2012, illustrate that this second grid line 101 is in off-state.So, can avoid in the time that the first grid line 100 or the second grid line 101 connect the first detection line 11 and the second detection line 12 simultaneously, because test signal is received by the signal receiver on grid line to be measured after by the grid line adjacent with grid line to be detected, and cause the phenomenon that the off state of grid line to be measured cannot detect to produce, thereby can detect the break-make situation of grid line to be measured exactly.
It should be noted that, preferred, secondary signal can be received to subelement 2012 and be arranged at the side of the second grid line 101 near the second detection line 12, so, can detect the break-make situation of whole the second grid line 101.Certainly, the position that those skilled in the art can also receive subelement 2012 to secondary signal by actual conditions is adjusted, for example, only need to detect the second grid line 101 of close the first detection line 11 parts time, this secondary signal reception subelement 2012 can be arranged to the centre position of the second grid line 101.
It should be noted that; below be all take the first grid line 100 as even number line grid line, the explanation carried out as odd-numbered line grid line as example of the second grid line 101; when the first grid line 100 is odd-numbered line grid line; when the second grid line 101 is even number line grid line; or testing process when from the first grid line 100 of other type of the different generations of the first detection line 11 and the second detection line 12 connected modes and the second grid line 101 in like manner can obtain; here repeat no more, but all should belong to protection scope of the present invention.
Further, as shown in Figure 6, in the time that the first grid line 100 is connected with the first detection line 11; The method that first signal Transmit-Receive Unit 200 is set on the first grid line 100 can also comprise:
First signal is set on the first grid line 100 and receives subelement 2002.
In the time that the second grid line 101 is connected with the second detection line 12 with the first detection line 11; The method that secondary signal Transmit-Receive Unit 201 is set on the second grid line 101 can also comprise:
Secondary signal is set in one end of the second grid line 101 and sends subelement 2011, the other end arranges secondary signal and receives subelement 2012.
Concrete, as shown in Figure 6, the first grid line 100(is even number line the 2nd, 8 row grid lines for example) be connected with the first detection line 11; The second grid line 101(is odd-numbered line the 1st, 7 row grid lines for example) be connected with the second detection line 12 with the first detection line 11.In the time that the secondary signal transmission subelement 2011 arranging on the second grid line 101 sends detection signal, because second grid line 101 adjacent with this first grid line 100 is connected with the second detection line 12 with the first detection line 11 simultaneously, therefore this detection signal can be divided into two parts, a part is sent to the second grid line 101, and another part is sent to the first grid line 100 by the first detection line 11.
Therefore, can receive above-mentioned detection signal if the secondary signal on the second grid line 101 receives subelement 2012, illustrate that this second grid line 101 is in conducting state; If the secondary signal on the second grid line 101 receives subelement 2012 and fails to receive above-mentioned detection signal, illustrate that this second grid line 101 is in off-state.In like manner, can receive above-mentioned detection signal if be arranged at the first grid line 100 near the first signal reception subelement 2002 of the second detection line 12 1 sides, illustrate that this first grid line 100 is in conducting state; Fail to receive above-mentioned detection signal if first signal receives subelement 2002, illustrate that this first grid line 100 is in off-state.So, can avoid in the time that the first grid line 100 or the second grid line 101 connect the first detection line 11 and the second detection line 12 simultaneously, because test signal is received by the signal receiver on grid line to be measured after by the grid line adjacent with grid line to be detected, and cause the phenomenon that the off state of grid line to be measured cannot detect to produce, thereby can detect the break-make situation of grid line to be measured exactly.
It should be noted that, preferred, first signal can be received to subelement 2002 and be arranged at the side of the first grid line 100 near the second detection line 12, so, can detect the break-make situation of whole the first grid line 100.Certainly, the position that those skilled in the art can also receive subelement 2002 to first signal by actual conditions is adjusted, for example, only need to detect the first grid line 100 of close the first detection line 11 parts time, this first signal reception subelement 2002 can be arranged to the centre position of the first grid line 100.
It should be noted that; below be all take the first grid line 100 as even number line grid line, the explanation carried out as odd-numbered line grid line as example of the second grid line 101; when the first grid line 100 is odd-numbered line grid line; when the second grid line 101 is even number line grid line; or testing process when from the first grid line 100 of other type of the different generations of the first detection line 11 and the second detection line 12 connected modes and the second grid line 101 in like manner can obtain; here repeat no more, but all should belong to protection scope of the present invention.
Further, above-mentioned array base palte detection method can also comprise:
Intensity and the preset value of the detection signal that first signal Transmit-Receive Unit 200 or secondary signal Transmit-Receive Unit 201 are received compare, so that the first grid line 100 or the second opening circuit of grid line 101 are detected.So, can be using above-mentioned preset value as reference, make the judgement of the on off operating mode to the first grid line 100 or the second grid line 101 more directly perceived.
Wherein, those skilled in the art can need to set above-mentioned preset value according to actual production processing.Preferably, above-mentioned preset value can be numerically equal to the intensity of the above-mentioned detection signal that first signal Transmit-Receive Unit 200 or secondary signal Transmit-Receive Unit 201 receive.Take Fig. 3 as example, above-mentioned preset value can be numerically equal to first signal and receive subelement 2002 or secondary signal and receive the intensity of the detection signal that subelement 2012 receives.
Concrete, when the first grid line 100(is as the grid line of even number line the 2nd row) and the second grid line 101(as the grid line of odd-numbered line the 1st row) during all in conducting state, first signal receives the intensity that subelement 2002 and secondary signal receive the detection signal that subelement 2012 receives and equals above-mentioned preset value.When the first grid line 100(is as the grid line of even number line eighth row) in conducting state, and the second grid line 101(is as the grid line of odd-numbered line the 7th row) in the time of off state.The intensity of the detection signal that first signal reception subelement 2002 receives can be greater than preset value.Because, because the second grid line 101 opens circuit, so secondary signal receives subelement 2012 and does not receive the detection signal that secondary signal transmission subelement 2011 sends, and this detection signal is all received by first signal reception subelement 2002, so the intensity of the detection signal that first signal reception subelement 2002 receives can be greater than preset value.So, can make the judgement of the on off operating mode to the first grid line 100 or the second grid line 101 easier, directly perceived.
The embodiment of the present invention provides a kind of array substrate detecting device, as shown in Figure 7, can comprise:
At least one first signal Transmit-Receive Unit 200, is arranged on the first grid line 100, for sending or receive detection signal.
At least one secondary signal Transmit-Receive Unit, is arranged on the second grid line 101, for sending or receive above-mentioned detection signal.
It should be noted that, above-mentioned detection signal, for detection of the on off operating mode of the first grid line 100 or the second grid line 101.First signal Transmit-Receive Unit 200 and secondary signal Transmit-Receive Unit 201 can receive above-mentioned detection signal, can receive again this detection signal.
The embodiment of the present invention provides a kind of array substrate detecting device, this device comprises: be arranged on the first grid line, for sending or receive at least one first signal Transmit-Receive Unit of detection signal and being arranged at the second grid line, for sending or receive at least one secondary signal Transmit-Receive Unit of above-mentioned detection signal.During due to detection, the first grid line is connected with the first detection line, and the second grid line is connected with the second detection line; Or, be connected with the second detection line with the first detection line.So, can avoid two adjacent grid lines to be connected with the first detection line and the second detection line in testing process by this device time simultaneously, test signal can be by being received by the signal receiver on grid line to be measured after the grid line adjacent with grid line to be detected, and cause the phenomenon that the off state of grid line to be measured cannot detect to produce, thereby can detect the break-make situation of grid line to be measured exactly.
Preferably, first signal Transmit-Receive Unit 200 comprises:
First signal sends subelement 2001, for sending detection signal to the first grid line 100.
First signal receives subelement 2002, for receiving the detection signal of the first grid line 100.
Preferably, secondary signal Transmit-Receive Unit 201 comprises:
Secondary signal sends subelement 2011, for sending detection signal to the second grid line 101;
Secondary signal receives subelement 2012, for receiving the detection signal of the second grid line 101.
So, can be according to the first grid line 100 and the second grid line 101 connected mode different from the first detection line 11 or the second detection line 12, the position that above-mentioned first signal is sent to subelement 2001, first signal reception subelement 2002 and secondary signal transmission subelement 2011, secondary signal reception subelement 2012 arranges.
For example, shown in Fig. 4, the first grid line 100(is even number line the 2nd, 8 row grid lines for example) be connected with the first detection line 11; The second grid line 101(is odd-numbered line the 1st, 7 row grid lines for example) be connected with the second detection line 12.First signal can be set in one end of the first grid line 100 and send subelement 2001, the other end arranges first signal and receives subelement 2002; Secondary signal transmission subelement 2011 other ends are set in one end of the second grid line 101 secondary signal reception subelement 2012 is set.In the time that first signal transmission subelement 2001 sends detection signal to the first grid line 100, if receiving subelement 2002, first signal receives above-mentioned detection signal, illustrate that the first grid line 100 is in conducting state; If first signal receives subelement 2002 and fails to receive above-mentioned detection signal, illustrate that the first grid line 100 is in off state.This array substrate detecting device is the same for the detection case of the second grid line 101.So, because the first grid line 100 connects different detection lines from the second grid line 101, therefore pass through above-mentioned detection device, in testing process, can avoid in the time that the first grid line 100 or the second grid line 101 connect the first detection line 11 and the second detection line 12 simultaneously, because test signal is received by the signal receiver on grid line to be measured after by the grid line adjacent with grid line to be detected, and cause the phenomenon that the off state of grid line to be measured cannot detect to produce, thereby can detect the break-make situation of grid line to be measured exactly.
Again for example, shown in Fig. 6, the first grid line 100(is even number line the 2nd, 8 row grid lines for example) be connected with the first detection line 11; The second grid line 101(is odd-numbered line the 1st, 7 row grid lines for example) be connected with the second detection line 12 with the first detection line 11.Can near one end of the second detection line 12, first signal be set at the first grid line 100 and receive subelement 2002; Secondary signal is set in one end of the second grid line 101 and sends subelement 2011, the other end arranges secondary signal and receives subelement 2012.In the time that the secondary signal transmission subelement 2011 arranging on the second grid line 101 sends detection signal, because second grid line 101 adjacent with this first grid line 100 is connected with the second detection line 12 with the first detection line 11 simultaneously, therefore this detection signal can be divided into two parts, a part is sent to the second grid line 101, and another part is sent to the first grid line 100 by the first detection line 11.
Therefore, can receive above-mentioned detection signal if the secondary signal on the second grid line 101 receives subelement 2012, illustrate that this second grid line 101 is in conducting state; If the secondary signal on the second grid line 101 receives subelement 2012 and fails to receive above-mentioned detection signal, illustrate that this second grid line 101 is in off-state.In like manner, can receive above-mentioned detection signal if be arranged at the first grid line 100 near the first signal reception subelement 2002 of the second detection line 12 1 sides, illustrate that this first grid line 100 is in conducting state; Fail to receive above-mentioned detection signal if first signal receives subelement 2002, illustrate that this first grid line 100 is in off-state.So, pass through above-mentioned detection device, in testing process, can avoid in the time that the first grid line 100 or the second grid line 101 connect the first detection line 11 and the second detection line 12 simultaneously, because test signal is received by the signal receiver on grid line to be measured after by the grid line adjacent with grid line to be detected, and cause the phenomenon that the off state of grid line to be measured cannot detect to produce, thereby can detect the break-make situation of grid line to be measured exactly.
Other sends subelement 2001, first signal for first signal and receives subelement 2002 and secondary signal and send subelement 2011, secondary signal and receive being arranged on this and giving an example no longer one by one of subelement 2012 positions, but all should belong to protection scope of the present invention.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, any be familiar with those skilled in the art the present invention disclose technical scope in; can expect easily changing or replacing, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of described claim.
