Description
Technical field
The invention belongs to display technique field, be specifically related to a kind of display panel detection architecture, display panel and display device.
Background technology
In thin-film transistor LCD device (TFT-LCD) product, along with the continuous lifting of user's demand for experience, the demand of high resolving power (PPI) product is also improved constantly.Therefore in order to meet the demand of high definition pixel product, with more pixel cell (namely data line now and the quantity of sweep trace increase) will be set in the measure-alike display panel of display panel in the past, now whether existed the normal data signal line of detection architecture of data line line bad (X-Line) and the wire laying mode of switch signal line (Switch) (being provided with detector switch unit at the infall of data detection signal line and switch signal line) can not meet high PPI designing requirement in Fanout district (fan section) in for detection of display panel in the past, detector switch unit need to be increased to 6 rows and design the intensive winding displacement mode of the data line that meets display panel from original 2 rows.But also bring much bad, mainly wherein between equipment and substrate, easily to produce in process of production static, 1/2 place in display panel detection architecture produces electrostatic discharge (ESD) (the namely position of a in figure), causes occurring under E/T 6% line bad (X-Line).
As shown in Figure 1, for being located at a kind of display panel detection architecture in Fanout district in prior art, comprise: data-signal port one 01, data detection signal line 103, switch signal line 102, and the detector switch unit K of data detection signal line 103 and switch signal line 102 infalls is set; Described data detection signal line 103 connects by the described detector switch unit K data-signal port one 01 corresponding with it; The detector switch unit K that is located at same row is chained together, and controls by same switch signal line 102, and the detector switch unit K of two adjacent column controls by different switch signal line 102.Produce in the detection architecture process of this display panel manufacturing, easily be subject to the impact of environment static, be 8000V according to the antistatic effect of product, illustrate that the right side being easy in Fanout zone centerline, near the position of first detector switch unit K of display panel, ESD occurs, bring and have a strong impact on to the stable yield of product, be badly in need of finding feasible way thoroughly to stop this bad generation.In design by symmetric points and other positions, contrast, infer and only occurring that the fixed position that ESD is ordered is the most easily to assemble electric charge do not having other channels to disperse, under the condition of electric charge, easily to produce high temperature, make Gate(grid) and SD(source-drain electrode) metal punctures, and produces short circuit (short).Therefore, how the electric charge of a of first K place, detector switch unit of Fanout district is disperseed to become key factor.
By existing design, as shown in Figure 2.By first and second detector switch unit K laser cutting in normal Fanout district, be labeled as analog D ummy Switch(redundancy switching element Q) district, therefore, the detector switch unit K in the square frame of right side will become first detector switch unit Kb on actual Fanout zone centerline right side.Afterwards this SD Cutting place is impacted 5 times continuously with 10000V static, after microscopy, in 21, there are 3 this position ESD, therefore, can judge that the SD line below first detector switch unit K of a position in this ESD and Fig. 1 is irrelevant, meanwhile, also verified the generation that can effectively prevent ESD at the Dummy Switch of a same design of first detector switch unit K left side increase.
