In addition, in order to improve the degree of regulation to distance between test equipment 6 and LCM to be measured, in the present embodiment, branch
Scale (not indicated in figure) is additionally provided with fagging 3, length direction of the scale along slideway 31 is set, in test equipment 6 in supporting plate 3
On along slideway 31 slide when, the distance that test equipment 6 is slided can be determined by scale, and then can more accurately adjust test
The distance that equipment 6 is slided along slideway 31.
Also, in the present embodiment, as shown in figure 1, fixed mount includes the first fixed plate 21 and the second fixed plate 22, and
First fixed plate 21 and the second fixed plate 22 are oppositely arranged, and are integrally formed with substrate 1, thus it is seen that, the first fixed plate
21 and second fixed plate 22 and substrate 1 form space for accommodating LCM to be measured, and test equipment 6 can be in the space
Slide up and down or slided along the slideway 12 on substrate 1, so as to adjust the position relationship between test equipment 6 and LCM, with reality
Existing test equipment 6 is under diverse location to LCM testing requirement.Certainly, in the application process of reality, first can also be fixed
It is arranged to be detachably connected between the fixed plate 22 of plate 21 and second and substrate 1, for example, can be in substrate 1 relative to the first fixed plate
21 side sets Elastic buckle, while sets Elastic buckle relative to the side of the second fixed plate 22 in substrate 1, and first fixes
Fastener is provided with the fixed plate 22 of plate 21 and second accordingly, between the fixed plate 21 of substrate 1 and first and the second fixed plate 22
Realized and be detachably connected by buckle and fastener, first fixed plate 21 and the second fixed plate 22 are carried out more so as to convenient
Change, while can conveniently carry measurement jig.
Second embodiment of the present utility model is related to display module LCM measurement jig, second embodiment and first
The difference of embodiment is：In the first embodiment, as shown in figure 1, fixed mount includes the first fixed plate 21 and the
Two fixed plates 22, and the first fixed plate 21 and the second fixed plate 22 are formed in one with substrate 1.And in the present embodiment,
It is arranged to be detachably connected between first fixed plate 21 and the second fixed plate 22 and substrate 1.
Specifically, as shown in figure 4, the first fixed plate 21 includes horizontal segment and is connected with horizontal segment and vertical vertical
Section, the second fixed plate 22 includes horizontal segment and is connected with horizontal segment and vertical vertical section, and offers cavity in substrate 1, and
Cavity is extended up to through substrate towards the direction of the first fixed plate and the second fixed plate respectively in substrate, the first fixed plate 21
It is can be inserted into the horizontal segment of the second fixed plate 22 in cavity, and the horizontal segment of the first fixed plate 21 and the second fixed plate 22 can be
In cavity slidably.
By the above it is seen that, by the horizontal segment of the first fixed plate 21 and the second fixed plate 22 in substrate cavity
Inside slidably, the distance between the first fixed plate 21 and the second fixed plate 22 can be changed, so as to realize that measurement jig 6 is right
Different size LCM to be measured adaptability.When testing the less LCM to be measured of size, the first fixed plate of readjusting prices can be passed through
21 and second the distance between the fixed plate 22, reduce display module LCM measurement jig size.
It will be understood by those skilled in the art that the respective embodiments described above are to realize specific implementation of the present utility model
Example, and in actual applications, can to it, various changes can be made in the form and details, without departing from spirit of the present utility model
And scope.
