The detection method of the present embodiment adopts the data line of the pick-up unit shown in Fig. 1 to liquid crystal panel to detect, and does not repeat at this.The detection method of the present embodiment comprises the following steps:
Step S201, is connected the first sensor of pick-up unit and the second sensor correspondence with adjacent two data to be tested lines;
As can be seen from figures 8 and 9; Described first sensor 11, second sensor 12 is connected to the end of adjacent two data to be tested lines 102,101 or 104,103, and first sensor 11, second sensor 12 is positioned at the same side of data to be tested line 101,102,103,104.
Step S202, controls the detection signal that first sensor receives to the input of data to be tested line, starts timing simultaneously, and controls the detection signal of the second sensor reception through data line transfer to be detected;
As shown in Figure 8, described control module 13 sends control signal to signal module 14, signal module 14 inputs detection signal according to this control signal to first sensor 11, the detection signal input data to be tested line 102 that first sensor 11 will receive, described second sensor 12 is for receiving the detection signal transmitted through data to be tested line 101.As shown in Figure 9, the detection signal input data to be tested line 104 that first sensor 11 will receive, described second sensor 12 is for receiving the detection signal transmitted through data to be tested line 103.
Step S203, judges whether the second sensor receives detection signal;
After inputting detection signal to data to be tested line 102, judge whether the second sensor 12 receives signal, when the second sensor 12 receives signal (spiking 105 as shown in Figure 10), perform step S204; When the second sensor 12 does not receive detection signal, perform step S205.
As shown in Figure 8, when first sensor 11 inputs detection signal to data to be tested line 102, without being electrically connected, therefore, when the second sensor 12 be connected with data to be tested line 101 one end does not receive detection signal between data to be tested line 102 and adjacent data to be tested line 101.
As shown in Figure 9, when first sensor 11 inputs detection signal to data to be tested line 104, there is short circuit between data to be tested line 104 and adjacent data to be tested line 103 and be connected 106, then a part for the detection signal of first sensor 11 input will continue to transmit along data to be tested line 104, another part then transmits along data to be tested line 103 after short circuit connects 106, therefore the second sensor 12 be connected with data to be tested line 103 one end can receive detection signal, spiking 105 as shown in Figure 10.
Step S204, judges that there is short circuit between described two adjacent testing data lines stops timing simultaneously, calculates the position of short circuit, and proceeds to step S205;
When the second sensor 12 receives detection signal, then can judge to there is short circuit between described two adjacent data to be tested lines.As shown in FIG. 9 and 10, when the second sensor 12 receives detection signal, then represent data to be tested line 103 and there is short circuit between data to be tested line 104 and be connected, data line 103,104 to be detected is marked.
The position calculating short circuit is specially: calculate the transmission time of detection signal in data to be tested line; According to the position of the distance computation short circuit between the transmission time of detection signal in data to be tested line, transmission speed and adjacent two data lines.
In the present embodiment, in step S202, first sensor 11 starts timing when data to be tested line 104 inputs detection signal, and stop timing when the second sensor 12 receives detection signal, therefore can be calculated the transmission time t of detection signal in data to be tested line; And detection signal is electric signal, and its transmission speed v is known, can calculate the transmission range S of detection signal, S=vt.In addition the space D between data to be tested line is known, and first sensor 11 and the second sensor 12 are set up in parallel, therefore the distance L=(S-D between location of short circuit and first sensor 11 or the second sensor 12)/2, the short circuit that can draw between data to be tested line 103,104 connects the position of 106.In other embodiments, after determining that short circuit connects the position of 106, can the methods such as cut be adopted, disconnect short circuit and connect 106, thus the circuit defect between adjacent two data to be tested lines can be repaired.
Step S205, controls first sensor and the second sensor moves according to the direction of presetting.
After these two adjacent data to be tested lines detections terminate, then control first sensor 11 and the second sensor 12 move according to the direction of presetting, and return step S201, data line to be detected is detected, until all data to be tested lines all detect complete.
The detection method of the present embodiment, not only can detect the data line that there is short circuit exactly, and accurately can also mark the particular location of short circuit between two data lines, further increases the efficiency of short-circuit detecting.
