Abstract
The utility model discloses a kind of TP holding wire line test plate, comprise the TP test interface be connected with TP interface connector on LCM, the packaged resistance be connected with TP test interface by circuit, the LED connected one to one with packaged resistance and the test PAD be connected with each LED negative pole.The utility model is plugged on the TP interface connector of LCM by TP test interface, and, by module FPC? the circuit that PIN interface is corresponding receives the positive pole of digital power, the test PAD that LED negative pole connects receives the negative pole of digital power, upper electrical testing, thus TP holding wire circuit OK when LCM produces can be realized, bad without open circuit, short circuit etc.Further, defect ratio and scrap cost after sale can be reduced.
Description
Technical field
The utility model relates to LCM testing equipment, a kind of TP holding wire line test plate particularly related to.
Background technology
In prior art, in LCM testing equipment, generally TP holding wire circuit is not tested, thus when causing LCM to produce, cannot know that the TP holding wire circuit on LCM FPC is bad with or without open circuit, short circuit etc., and, after sale time, client reaches the standard grade assembling, and because LCM FPC TP holding wire short out (breaking) road causes TP ineffective or lost efficacy, it is bad that this is judged to module entirety, need reprocess or scrap, strengthen cost.
Therefore, prior art existing defects, needs to improve.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of and can apply FPC in LCM and walk holding wire line test needed for TP, reduce the TP holding wire line test plate of defect ratio and scrap cost after sale.
The technical solution of the utility model is as follows: a kind of TP holding wire line test plate, comprises the TP test interface be connected with TP interface connector on LCM, the packaged resistance be connected with TP test interface by circuit, the LED connected one to one with packaged resistance and the test PAD be connected with each LED negative pole.
Be applied to technique scheme, in described TP holding wire line test plate, it is provided with six packaged resistances and is provided with and packaged resistance six LED one to one, and each packaged resistance is connected with TP test interface by a circuit.
Adopt such scheme, the utility model is plugged on the TP interface connector of LCM by TP test interface, and, circuit corresponding for module FPC PIN interface is received the positive pole of digital power, the test PAD that LED negative pole connects receives the negative pole of digital power, upper electrical testing, thus TP holding wire circuit OK when LCM produces can be realized, bad without open circuit, short circuit etc.Further, defect ratio and scrap cost after sale can be reduced.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Present embodiments provide a kind of TP holding wire line test plate, as shown in Figure 1, TP holding wire line test plate comprises TP test interface 101, LCM, i.e. liquid crystal display, FPC, namely TP interface connector is provided with in FPC, TP test interface 101 is plugged on the TP interface connector of LCM, TP test interface 101 is connected with packaged resistance 102 by circuit, wherein, be provided with six encapsulated circuits 102, i.e. packaged resistance R1, packaged resistance R2, packaged resistance R3, packaged resistance R4, packaged resistance R5 and packaged resistance R6, each packaged resistance by one independently circuit be connected with TP test interface 101 respectively, and, the LED103 connected one to one with packaged resistance is also set, six corresponding LED are such as set, comprising LED D1, LED D2, LED D3, LED D4, LED D5, LED D6, and, the test PAD104 be also provided with, test PAD104 is connected with the negative pole of each LED.
Wherein testing PAD is a testing weld pad, when testing, first, test board is reached TP circuit on LCD module FPC by TP test interface 101 and test board is connected.Then, circuit corresponding for module FPC PIN interface is received the positive pole of digital power, the test PAD104 that LED negative pole connects receives the negative pole of digital power, powers on.So, during path, LED is single bright; During open circuit, LED does not then work; Short circuit then corresponding KED lamp is bright, and wherein at least 2 lamps are bright.
These are only preferred embodiment of the present utility model, be not limited to the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
