Description
Technical field
The utility model relates to display technique field, and the lighting especially relating to a kind of liquid crystal panel detects tool.
Background technology
Liquid crystal indicator has that image quality is good, volume is little, lightweight, low driving voltage, low-power consumption, the advantage that radiationless and manufacturing cost is relatively low, occupy an leading position in flat display field at present.The principle of work of liquid crystal indicator is: be applied to the liquid crystal layer between thin-film transistor array base-plate and colored filter (color filter) substrate by suitable voltage, liquid crystal molecule in liquid crystal layer is deflected under voltage effect, by different Control of Voltage to obtain different penetrances, thus realize picture display.
The manufacture process of liquid crystal indicator is divided into the vertical processing procedure (cell processing procedure) of array process (array processing procedure), group and module group procedure (module processing procedure) substantially.Array process makes on the glass substrate, thin film transistor (TFT) to obtain thin-film transistor array base-plate.The vertical processing procedure of group is combined with colored filter substrate by the thin-film transistor array base-plate obtained, and enclose liquid crystal between two substrates, more large stretch of glass-cutting is become multiple liquid crystal panel.Module group procedure is fitted together the liquid crystal panel obtained and other assemblies such as backlight, driving chip etc.
In the vertical processing procedure of group, general needs carry out lighting detection (light on test to the liquid crystal panel obtained, LOT), lighting detects and refers to the detection mode being adopted short bar (shorting bar) by lighting machine, test signal is sent in liquid crystal panel by short bar panel is lighted, whether have picture element flaw to detect liquid crystal panel.Please refer to the drawing 1, by R, G, B data lines all in liquid crystal panel 10 is gone out test point 12,13,14 in periphery by short bar 11 short circuit respectively, simultaneously by all odd-numbered scan lines 18 and all even-line interlace lines 19 respectively short circuit go out test point 15,16.When carrying out picture test, test signal is applied to corresponding test point 12,13,14,15,16 by lighting machine, can light liquid crystal panel 10 and carry out pixel defect check.After completing detection, by using laser machine (laser), short bar test lead is cut off, namely in the position at dotted line 17 place of Fig. 1, short bar test lead is cut off, on liquid crystal panel, attach polaroid again after cut-out, then carry out the module group procedure of next stage.
In order to lighting testing result is associated with tested liquid crystal panel, be beneficial to after liquid crystal panel is sold away, be convenient to producer and consumer carries out quality tracing (finding that product problem can look for producer's maintenance free etc. as consumer is under warranty) to product, the operation of the identify label (ID) of the tested liquid crystal panel of one reading was also comprised before lighting detects, each liquid crystal panel is printed on the identify label of a uniqueness, the identify label of each liquid crystal panel is different and have uniqueness, therefore the result finding the early stage lighting of corresponding liquid crystal panel to detect can be reviewed by identify label.
In prior art, before lighting detection is carried out to liquid crystal panel, in a upper procedure, first the identify label of liquid crystal panel is read in scanning, after the identify label that have read liquid crystal panel, is placed in by liquid crystal panel on lighting machine and carries out lighting detection in next process.In other words, in existing mode, identify label reading and lighting detect separately to be carried out on two boards (scanning machine and lighting board), liquid crystal panel is first placed on scanning machine by operator, calibrate positions of panels, with scanning machine, liquid crystal panel is scanned, to read the identify label being imprinted on liquid crystal panel; Afterwards, then liquid crystal panel is transferred on lighting board, has calibrated positions of panels, with lighting machine, liquid crystal panel has been tested.But, above-mentioned identify label reading and lighting detect because separately two procedures is carried out, need to use mechanical arm or shifting apparatus to transfer liquid crystal panel between different platform, add probability liquid crystal panel being polluted or damages, in every procedure, all need the program of liquid crystal panel being carried out to position correction simultaneously, cause pitch time (tact time) to extend, reduce detection efficiency and production capacity.
Utility model content
The purpose of this utility model is that the lighting providing a kind of liquid crystal panel detects tool, the identify label reading of liquid crystal panel and lighting is detected to be incorporated on a board and carries out, shorten pitch time, improve detection efficiency and production capacity.
The utility model embodiment provides a kind of lighting of liquid crystal panel to detect tool, comprise probe base, probe and ID reading devices, described probe and described ID reading devices are all arranged on described probe base, described probe is for contacting to send into test signal when lighting detects in liquid crystal panel with the test point on liquid crystal panel, and described ID reading devices is for reading the identify label on liquid crystal panel.
Further, described ID reading devices closes on the setting of described probe on described probe base.
Further, the quantity of described probe base is two, and be respectively the first probe base and the second probe base, each probe base is provided with described probe, described ID reading devices is only arranged on one of them probe base.
Further, described ID reading devices is CCD reading device or laser reading device.
The utility model embodiment has the following advantages: arrange ID reading devices by integrated on the probe base of lighting detection tool, ID reading devices being incorporated into lighting detects on tool, the reading of identify label and lighting combining data detection are completed in same procedure, be equivalent to decrease a procedure, also just liquid crystal panel is transferred between different platform without the need to mechanical arm or shifting apparatus, reduce probability liquid crystal panel being polluted or damages, also save the one position correction program of liquid crystal panel on existing scanning machine simultaneously, decrease the pitch time (tact time) needed for lighting inspection process, improve detection efficiency, due to single liquid crystal panel lighting detect needed for pitch time can save at least 5 seconds, therefore entirety can promote production capacity about 8%.
