In raised 21 with liquid crystal display module rear-face contact, attachment structure can adjust the distance between pressing plate 2 and fixed frame.
That is, above testing equipment includes the fixed frame for accommodating liquid crystal display module.The front frame of the fixed frame
11 are used to be contacted with the edge part of liquid crystal display module front (i.e. liquid crystal display panel is used for the one side for being shown), so as to limit
The forward movement of liquid crystal display module is made, while not influenceing display again；And the after-frame 12 of fixed frame is then used for and liquid crystal display
The back side (i.e. one side of the backlight away from the liquid crystal display panel) contact of module, so as to limit the shifting backward of liquid crystal display module
It is dynamic.Thus, liquid crystal display module is stuck between front frame 11 and after-frame 12.
And (i.e. side of the after-frame 12 away from front frame 11) is additionally provided with pressing plate 2 after after-frame 12, it is provided with the pressing plate 2
Raised the 21 of fixed frame, and pressing plate 2 is connected by attachment structure with fixed frame, the attachment structure can adjust fixed frame and pressing plate 2
Between distance, so as to can also change raised 21 the distance between with fixed frame, that is, change raised 21 pairs in fixed frame
Liquid crystal display module apply power.
In the testing equipment of the present embodiment, liquid crystal display module can be fixed between front frame 11 and after-frame 12, by even
Distance between binding structure adjustable pressure plate 2 and fixed frame, also with regard to the raised 21 pairs of liquid crystal display module back sides on adjustable pressure plate 2
The pressure of applying is simulating finger pressure；Because raised 21 position determines, and the regulation that attachment structure is adjusted the distance is controllable, therefore the detection
Equipment can accurately control to simulate position and the pressure of finger pressure, so as to accurately carry out finger pressure detection, improve the efficiency of detection, reduce
False Rate.
Preferably, front frame 11 includes for the vertical portion that is connected with the edge part of after-frame 12, and be connected to vertical portion away from
The one end of after-frame 12 and to inside liquid crystal display module extend horizontal part, formed for holding between horizontal part, vertical portion, after-frame 12
Receive the draw-in groove of liquid crystal display module edge part.
That is, as shown in Fig. 2 front frame 11 preferably include bending structure so that it can shape when being located on after-frame 12
Into the draw-in groove for accommodating liquid crystal display module edge part.
Preferably, as a kind of mode of the present embodiment, front frame 11 is fixedly connected with after-frame 12, at least side of front frame 11
With the opening for feed flow crystalline substance display module insertion.
That is, front frame 11 can be structure as a whole with after-frame 12, thus, fixed in order to liquid crystal display module can be entered
In basket, then front frame 11 can not four sides close, but should in an at least side opening, so as to by liquid crystal display module along the opening
Insertion.
Preferably, as the another way of the present embodiment, front frame 11 is detachably connected with after-frame 12.
That is, front frame 11 can also be pulled down from after-frame 12, thus can first by liquid crystal display module as
On after-frame 12, front frame 11 is connected with after-frame 12 again afterwards, liquid crystal display module is fixed.
It is furthermore preferred that being detachably connected as clamping above.
That is, front frame 11 and after-frame 12 are preferably by clamping (such as after 11 points of front frame is two parts, and there is confession inner side
Frame 12 insertion draw-in groove) mode realize being detachably connected.Certainly, if realizing front frame by other manners such as screw connections
11 are detachably connected with after-frame 12, are also feasible.
Preferably, after-frame 12 includes the back plate for supporting the liquid crystal display module back side, has in back plate multiple for supplying
Raised 21 through holes for passing through.
That is, as shown in Figure 1 to Figure 3, after-frame 12 can be integrally tabular, and in the plate respective protrusions 21 position
Multiple holes are provided with, for being passed through for raised 21.
Certainly, after-frame 12 or other forms, such as after-frame 12 can be similar with front frame 11, is also only corresponding liquid crystal display
The framework of module marginal position.
Preferably, as a kind of mode of the present embodiment, the quantity of pressing plate 2 is one, which is provided with multiple raised 21.
In a display device, the back side of liquid crystal display module is typically mainly subject to from multiple high points for determining in housing
Pressure, and the pressure value of these high points is typically more or less the same.Therefore, the projection of each high point of correspondence can be set on a pressing plate 2
21, in detection, these projections 21 are synchronized with the movement with pressing plate 2, and essentially identical to the pressure of liquid crystal display module, so that
Realize that finger pressure is detected with simplest structures and methods.Certainly, above testing equipment enters to the liquid crystal display module of different model
, it is necessary to use different pressing plates 2 during row detection.
Preferably, as the another way of the present embodiment, the quantity of pressing plate 2 is multiple.
That is, it is also possible to have multiple pressing plates 2, each pressing plate 2 is individually connected by attachment structure with fixed frame,
And one or more projections 21 are designed with each pressing plate 2.So, can be determined to use according to the concrete model of liquid crystal display module
Which pressing plate 2 applies pressure to which position.
Preferably, attachment structure includes bolt 31, the one end of bolt 31 connection knob 32；It is provided with after-frame 12 and 31, bolt
The screw matched somebody with somebody, is provided with the via for being passed through for bolt 31 in pressing plate 2, bolt 31 passes through screw and via, knob 32 to be stuck in pressure
Side of the plate 2 away from fixed frame.
As shown in Figure 2 and Figure 3, a bolt 31 is connected on after-frame 12 by screw, and the other end fixation of bolt 31 sets
Have knob 32, knob 32 is stuck in outside pressing plate 2, therefore by turn knob 32 bolt 31 can be driven to rotate, make knob 32 away from or lean on
Nearly after-frame 12, while also make to be screwed 32 pressing plates 2 for blocking away from or near after-frame 12, and then adjust on pressing plate 2 raised 21
To the pressure of liquid crystal display module.
Certainly, the concrete form of attachment structure is not limited to this.For example, it is also possible to be after the one end of bolt 31 is fixedly connected on
On frame 12, knob 32 is still stuck in outside pressing plate 2, but there is screw the inner side of knob 32, therefore can be in bolt 31 by turn knob 32
Diverse location is moved, and also be may move so as to be screwed 32 pressing plates 2 for blocking.
Preferably, knob 32 is provided with scale.
That is, scale can be set on knob 32, to indicate the rotational case or liquid crystal display module of knob 32
Stressing conditions (stressing conditions want measured in advance with the relation of the position of knob 32), accurately to control to be applied to liquid crystal display module
Plus pressure, realization more accurately detect.
It is understood that embodiment of above be merely to illustrate that principle of the present utility model and use it is exemplary
Implementation method, but the utility model is not limited thereto.For those skilled in the art, this is not being departed from
In the case of the spirit and essence of utility model, various changes and modifications can be made therein, and these variations and modifications are also considered as this reality
With new protection domain.
