One pedestal is coated and fixed on the link of the link of above-mentioned probe body and signal transmission line.
Wherein, above-mentioned signal transmission line end has a winding displacement, and terminal remittance of this winding displacement put in order in above-mentioned plug.
Wherein, these some signal transmission lines pass the outer part bundle of this pedestal and are combined in the heat-shrinkable T bush.
Wherein, the end of probe of above-mentioned probe body has the exposed portion of stretching out this pedestal outside.
Wherein, the exposed minister's degree of above-mentioned end of probe is less than the length of being fixed by this pedestal.
Wherein, has position, plurality of fixed hole on this pedestal.
The utility model progress effect:
The utility model is reached one of purpose and effect, and this probe body contacts with display panel to be measured to form electrically and engages, and sees through this signal transmission line and exports signal to the detecting computer, and whether the effect that detects each pixel according to this is normal.
The utility model is reached two of purpose and effect, the utility model detector probe can according to the specification modularity of display panel to be detected manufacture different size, when detecting, cooperate the display panel specification to change.
The utility model is reached three of purpose and effect; detector probe of the present utility model mainly is plugged in the specific connector of detecting computer circuits plate with the plug of specific kenel; and plug and circuit board connector have corresponding specific kenel; even what the operator was also can be with the mode of groping in the darkroom very fast engages both are corresponding; for the operator; the utility model has promoted practicality and convenience, and the protection detector probe can be not impaired because of engaging of mistake with detecting computer circuits plate.
The utility model is reached four of purpose and effect, has promoted the stability of this probe body, improves the accuracy of test result.
Below in conjunction with accompanying drawing the utility model preferred embodiment is described.

Embodiment
As Fig. 2, Fig. 3, Fig. 4, the utility model detects the device of display panel pixel unit, comprises:
The probe body 30 of some predetermined numbers, arranged side by side with predetermined little spacing, the one end is a link 31, the other end is an end of probe 32; This end of probe 32 contacts according to this corresponding to pixel in order to the glass plate with the LCD measured panel;
The signal transmission line 40 that some numbers and probe body 30 are corresponding, the link 41 of each transmission line 40 connects surely with the link 31 of this probe body 30;
One pedestal 60 is coated and fixed the link 31 of above-mentioned probe body 30 and the link 41 of signal transmission line 40.And therefore make the end of probe 32 of this probe body 30 stretch out this pedestal 60 outsides, and its exposed length L 1 is significantly less than the length L 2 of being fixed by this pedestal 60 with a predetermined exposed length L 1.More establish position, plurality of fixed hole 61 on this pedestal 60, retaining element is fixed in tester table according to this;
Above-mentioned some signal transmission lines 40 pass outside the said base 60, promptly close with a heat-shrinkable T bush 43 bundles; These some signal transmission line 40 ends are converted to winding displacement 50 patterns of commonly seeing, and these winding displacement 50 terminal remittances are whole to be the plug 51 of a specific kenel, and this plug 51 is connected on the specific connector of detecting computer 80 circuit boards.
As Fig. 5, one display panel 70 to be measured is positioned one can be in length and breadth on the mobile objective table 71 of axle (X, Y-axis), said base 60 is fixed in a tester table, corresponding according to this each pixel of glass plate contact of 32 of the end of probe of this probe body 30 and LCD panel, contact to form electrical joint with display panel 70 to be measured by this probe body 30, see through above-mentioned signal transmission line 40 and export signal to detecting computer 80, whether the effect that detects each pixel according to this is normal.
The utility model detector probe also needs according to display panel specification (for example 15 o'clock, 17 o'clock, 19 o'clock ...) manufacture, because open described structure sample attitude on the utility model, but so modularity manufacture the detector probe of different size, when detecting, cooperate the display panel specification to change.Detecting operation carries out in the darkroom, the operator is with the plug 51 of these winding displacement 50 terminal specific kenels, insert in the specific connector of detecting computer 80 circuit boards and get final product, and plug 51 has corresponding specific kenel (the fool proof design that promptly is commonly called as) with circuit board connector, even what the operator was also can be with the mode of groping in the darkroom very fast engages both are corresponding, finish detector probe and detect engaging of computer.The utility model and prior art are compared, true suitable practicality and the convenience of tool, and also detector probe can be not impaired because of engaging of mistake with detecting computer circuits plate.
In addition, the end of probe 32 of the utility model probe body 30 is stretched out this pedestal 60 outsides with a predetermined exposed length L 1, and its exposed length L 1 is significantly less than the length L 2 of being fixed by this pedestal 60.So can promote the stability of this probe body 30, improve the accuracy of test result.
Though the utility model is to do explanation with a most preferred embodiment, is skillful in this skill person and can makes various multi-form changes not breaking away under the utility model spirit and the category.Above illustrated embodiment is only in order to explanation the utility model, and is non-in order to limit scope of the present utility model.Such as do not disobey various modifications or the variation that the utility model spirit is engaged in, all belong to the utility model claim.
