Description
Technical field
The present invention relates to a kind of method and device thereof that detects electrodes of flat panel display parts.
Background technology
The most advanced in the short circuit of electrode and the detection method that opens circuit in the existing flat-panel display device is that publication number is that the application for a patent for invention of CN1353858A " detects the short circuit of plasma display panel and the probe of the usefulness that opens circuit ", thereby it is the test of popping one's head in accurately and contacting the realization short circuit and open circuit with electrode by using, and its advantage is simple to operate and less to the electrode injury.But there is following deficiency simultaneously in it: 1. since general electrodes of flat panel display parts quantity about several thousand, using the probe test all is to detect by root usually, so efficiency of measurement is extremely low, and need compare through the data of microprocessor processes, further reduced its detection speed; 2. involve great expense.
Summary of the invention
In order to overcome above-mentioned deficiency, the purpose of this invention is to provide a kind of short circuit and method that opens circuit and device thereof that detects the electrode of flat-panel display device, the short circuit that it can the fast detecting electrode and open circuit and cheap.
The objective of the invention is to realize by following technical proposals.
Method of the present invention comprises following step:
1, add signal for an end of odd number strip electrode:, to illustrate that this odd electrode is a path, otherwise be to open circuit if can receive signal at the other end of odd number strip electrode.
2, add signal for an end of every strip electrode of even number bar:, to illustrate that this even electrode is a path, otherwise be to open circuit if can receive signal at the other end of even number strip electrode.
3, it is as follows specifically to be confirmed to be the method for short circuit between which two: in the process of execution in step 1 and step 2, if the other end of certain two adjacent electrode can both receive signal all the time, this two electric pole short circuit is described; If certain three adjacent electrode can both receive signal all the time, all short circuits between this three strip electrode are described then.
The described end of odd number strip electrode of giving adds that signal is a 220V DC voltage.
The described end of even number strip electrode of giving adds that signal is a 220V DC voltage.
The described signal that can receive at the other end of odd number strip electrode is a luminous signal.
The described signal that can receive at the other end of even number strip electrode is a luminous signal.
Device of the present invention is made up of the signal receiver of signal generator and series connection with it, and intervention 220V direct current, signal generator is made up of single-chip microcomputer, electromagnetic relay, flexible board and the current-limiting resistance of series connection successively, signal receiver is a pilot lamp, and the two ends of electrode to be measured are connected with signal generator and signal receiver respectively by flexible board.
The present invention is by the expansion and the use multi-disc single-chip microcomputer of single-chip processor i/o mouth, measure when can realize hundreds of electric pole short circuits and opening circuit, only need during detection respectively to add signal at an end of odevity strip electrode, whether luminous by the signal lamp that the identification other end receives, can illustrate that the odevity electrode is path or opens circuit or short circuit, thereby improve detection efficiency greatly; Because the present invention adopts the high pressure detecting electrode, the indeterminacy phenomenon of two inter-electrode short-circuit resistance when M Ω is above when having avoided low pressure to detection is so testing result is accurate simultaneously; Also because the electrode two ends adopt flexible board to be connected with circuit, because of not having any rolling or sliding friction between flexible board and electrode, so electrode is not had any injury.Structure of the present invention is very simple, and is cheap, and detecting operation is convenient and efficient, is easy to promote the use of.

Fig. 1 is a circuit block diagram of the present invention.
Fig. 2 is circuit theory diagrams of the present invention.
Specific embodiment
Below will be described in further detail the present invention by specific embodiment.
As shown in Figures 1 and 2, device of the present invention reaches the signal receiver that is connected in series with it by signal generator and forms, and intervention 220V direct current, signal generator is by single-chip microcomputer PIC, electromagnetic relay Z, and current-limiting resistance R and flexible board are formed, they are connected in series successively, signal receiver is a pilot lamp L, and electrode E to be measured draws with flexible board at two ends, is connected with relay and current-limiting resistance respectively.Its principle of work is:
(1) make it respectively in single-chip microcomputer odd number delivery outlet output 1 by the control knob control single chip computer, 10101010 signals are promptly exported in even number delivery outlet output 0.The relay that is connected with delivery outlet by single-chip microcomputer output signal control, when output signal is 1 when being high level, its corresponding relay adhesive, corresponding high-tension circuit connection.Because with the adhesive of odd electrode corresponding relays, so,, illustrate that electrode is disconnected if correspondingly pilot lamp does not work if corresponding this electrode of the bright explanation of pilot lamp is not disconnected.Because with the not adhesive of even electrode corresponding relays, so, illustrate that there are not short circuit in this electrode and adjacent electrode if the corresponding pilot lamp of the electrode of even number is dark.If the corresponding pilot lamp of even electrode is bright, then illustrate between the electrode that corresponding electrode is adjacent to have short circuit.
(2) detected confirm after, by control knob, control single chip computer makes it export 01010101 signal, i.e. odd number delivery outlet low level, even number delivery outlet output high level.Because with the adhesive of even electrode corresponding relays, so,, illustrate that electrode is disconnected if corresponding pilot lamp does not work if corresponding this electrode of the bright explanation of pilot lamp is not disconnected.Because with the not adhesive of odd electrode corresponding relays, so, illustrate that there are not short circuit in this electrode and adjacent electrode if the corresponding pilot lamp of the electrode of odd number is dark.If the corresponding pilot lamp of odd electrode is bright, then illustrate between the electrode that corresponding electrode is adjacent to have short circuit.
(3), short circuit between the electrode of these two or three correspondences is described then if in above two step operations, have adjacent two or three situations that pilot lamp is bright all the time.
