Description
Technical field
The utility model relates to detect jig field more particularly to a kind of backlight detection jig.
Background technique
For liquid crystal display device, since liquid crystal itself does not have the characteristics of luminescence, it is therefore necessary in liquid crystal display panel
Incident side add an illuminating source, such as backlight can realize the display function of liquid crystal display panel.The function of backlight
It can be to provide the area source that brightness is higher and is evenly distributed for liquid crystal display panel, liquid crystal display panel is enable normally to show
Image.And to backlight and display panel assembling when, due to the area BM (black matrix area) at display panel edge be it is lighttight,
At this moment it just needs backlight region corresponding with the area BM at display panel edge sticking openning glue and carrys out shielding light, it is existing with light leakage
As occurring.
During openning sticker is attached, often occur to attach exception, for example attach to the output optical zone of backlight, thus
Backlight output optical zone is caused to be blocked, light cannot appear, and then influence the display of liquid crystal display panel.Therefore it needs to paste in backlight
It is checked after attached good openning glue, be pasted with confirmation without exception, and currently used reviewing party's rule is that operator is direct
Human eye inspection, since the attached required precision of openning sticker is higher, there is very big error in personnel inspection, can not accurately determine, in turn
Cause detectability lower, missing inspection ratio is high, therefore is badly in need of designing a kind of detection instrument and accurately to detect backlight openning glue
It is pasted with without exception.

Fig. 1 is a kind of backlight detection jig structure figure of the utility model；Fig. 2 is a kind of backlight detection of the utility model
The warning device equivalent circuit diagram of jig；As shown in Figure 1, the utility model discloses a kind of backlights to detect jig 100, including
Pedestal 1 and the placing groove 11 for being used to place backlight 4 on pedestal 1, backlight 4 are equipped with openning glue 41.It further include cover board 2
And backlight 4 is lighted when detecting 41 attaching precision of openning glue and covers cover board 2 on backlight 4 by warning device 22, when
When openning glue 41 attaches abnormal, warning device 22 is alarmed.
Specifically, warning device 22 includes power supply 223, switch 224, photo resistance 222 and indicator light 221 in conjunction with Fig. 2,
Power supply 223, switch 224, photo resistance 222 and indicator light 221 are sequentially connected in series into circuit；Photo resistance 222 is set on cover board 2,
When cover board 2 is placed on backlight 4, photo resistance 222 will be located at the openning on 4 output optical zone 42 of backlight and close to backlight 4
Glue 41, when openning glue 41 attaches normal, indicator light 221 is bright；When openning glue 41 attaches abnormal, indicator light 221 goes out, and then makes
Warning device 22 is obtained to alarm.In the present embodiment, when cover board 2 is placed on backlight 4, photo resistance 222 is located at backlight 4 and goes out light
Add attaching precision most in area 42 and positioned at the width since the attaching edge of openning glue 41 toward 42 direction openning glue 41 of output optical zone
The position being worth greatly.Specifically, because the area BM (black matrix area) at display panel edge be it is lighttight, at this moment just need backlight
Region corresponding with the area BM at display panel edge sticks openning glue and carrys out shielding light, to prevent light leakage phenomena generation, therefore, openning glue
41 will be attached to the region of the corresponding liquid crystal display panel black matrix of backlight 4, and the width requirement of openning glue 41 and the width of black matrix are poor
It is few equal；And openning glue 41 can not attach to the region of the corresponding liquid crystal display panel black matrix of backlight 4 when attaching completely, therefore
There are problems that an attaching precision, in the present embodiment, attaching precision is less than 0.3mm.That is, in the present embodiment, photo resistance
222 will be located on cover board 2, in 4 output optical zone 42 of backlight and be located at since the attaching edge of openning glue 41 toward 42 side of output optical zone
The position attaching precision maximum value, that is, 0.3mm is added to the width in the corresponding area liquid crystal display panel BM.
Further, backlight 4 is surrounded by barricade 43, openning glue 41 be attached in output optical zone 42 and with backlight 4
On barricade 43 offset.Openning glue 41 positioned at 4 surrounding of backlight is connected or is not connected to two-by-two；Photo resistance 21 and openning glue
41 are arranged in a one-to-one correspondence.Specifically, in the present embodiment, it is corresponding when the openning glue 41 for being located at 4 surrounding of backlight is connected two-by-two
, photo resistance 21 is arranged in a one-to-one correspondence with openning glue 41 to be also connected two-by-two.Power supply 223, switch 224 and indicator light 221 are
One, when the openning glue 41 of 4 surrounding of backlight has a position to alarm when attaching abnormal.Preferably, being located at back
41 liang of openning glue of 4 surrounding of light source are all right one way or the other to be not connected to, at this point, photo resistance 21 and openning glue 41 are arranged in a one-to-one correspondence also two neither
It is connected, at this time the corresponding one group of power supply 223 of a photo resistance 21, switch 224 and indicator light 221, at this point, every openning glue 41 pastes
It can alarm when attached abnormal, can be as accurate as being that openning glue 41 attaches exception, and then corresponding carry out heavy industry in this way
Power consumption and material consumption are saved in repairing.
A kind of further backlight detection jig of the utility model further includes connector 3, and pedestal 1 and cover board 2 pass through company
Fitting 3 connects, and in the present embodiment, connector 3 is bolt or hinge.
Fig. 3 is structure chart when a kind of backlight detection jig backlight of the utility model is placed；Fig. 4 is the utility model one
Structure chart when kind backlight detection jig test；Illustrate that a kind of backlight detection of the utility model is controlled below with reference to Fig. 3 and Fig. 4
The use process of tool, as shown, in use, first backlight 4 can be placed in the placing groove 11 of pedestal 1, then
By the lighting terminal 12 being set on pedestal 1, backlight 4 is lighted.Then, cover board 2 is covered on backlight 4, and opens electricity
Source 223, at this time if openning glue 41 attach it is without exception if because the illumination of backlight 4 makes photo resistance 222 make photo resistance
222 photoresist reduces, then the circuit conducting that power supply 223, switch 224, photo resistance 222 and indicator light 221 are formed, indicator light
It is bright.If openning glue 41 attaches exception, the corresponding output optical zone of photo resistance 222 is completely or partially covered by openning glue 41, then photosensitive
Light under resistance 222 is not through, and such photo resistance 222 is not illuminated, and the resistance value of photo resistance 222 is constant, then power supply 223,
The circuit that switch 224, photo resistance 222 and indicator light 221 are formed is not turned on, and indicator light off.Therefore it can determine that the back tested at this time
If the openning glue 41 of light source 4 attaches exception.
A kind of backlight according to the present utility model detects jig, by the way that cover board and alarm dress are arranged on detection jig
It sets, when the detection attached precision of openning sticker, the backlight is lighted and by the cover plate lid on the backlight, when the mouth
When sub- sticker is attached abnormal, the warning device alarm.The backlight detection jig of the utility model not only can be convenient efficiently
The attaching for detecting backlight openning glue is abnormal, and designs simple, detection accuracy height.
