Description
The application be according to female case application (application number: 201010214416.5, denomination of invention: what display panels) propose divides an application.
Technical field
The present invention relates to a kind of display panel, and relate in particular to a kind of display panels.
Background technology
Traditional display panels is made of colored optical filtering substrates (Color Filter Substrate), thin-film transistor array base-plate (TFT Array Substrate) and the liquid crystal layer (Liquid Crystal Layer) that is disposed between this two substrates.More proposed now color filter film directly is integrated in (Color Filter on Array on thin-film transistor array base-plate, COA) or will deceive matrix is made in (Black matrix on Array on thin-film transistor array base-plate, BOA) technology, this technology is mainly that COA substrate or BOA substrate and another subtend substrate in batch is vertical, and insert liquid crystal molecule between two substrates, to form display panels.
Generally speaking, the practice of inserting liquid crystal layer mainly contains the vacuum inhalation and drips two kinds of formula injection methods (One drop fill, ODF).More do greatlyr along with the size of display panels, adopt the vacuum inhalation to insert time-consuming that liquid crystal phase works as.Therefore, in the vertical technique (Assembly process) of the group of large scale liquid crystal display panel, mostly adopt the formula injection method that drips to reach.Particularly, before the formula injection method that drips, can be prior to forming a frame glue on the border, viewing area of active component array base board, with around a liquid crystal spatial accommodation.Then, estimate the amount of splashing into of liquid crystal according to the size of liquid crystal spatial accommodation and the spacing of two substrates (cell gap), and the liquid crystal of designated volume is splashed in this liquid crystal spatial accommodation.At last, then active component array base board and colored optical filtering substrates are carried out hyte vertical, and make the frame adhesive curing with sealing liquid crystal between two substrates.
Yet; employing is dripped the formula injection method when inserting liquid crystal layer; regional near frame glue; liquid crystal molecule must diffuse to by frame glue by capillarity; in the display panels with COA substrate or BOA substrate, when liquid crystal molecule diffuses to contiguous frame glue, often can face the capillary force deficiency; cause liquid crystal molecule can't insert fully the contacting in perforation (via) of drain electrode of pixel electrode and active member, and easily produce bubbles of vacuum (bubble) in the contact perforation.Bubbles of vacuum can cause the yield of display panels to descend.Because bubbles of vacuum corresponds to drain electrode and the position that contacts perforation, therefore usually be difficult for being discovered by visual or image identification system, therefore, existing fabricator's use test ball knocks the edge (zone of contiguous frame glue) of display panels, with the problem (bubble issue) that further determines whether bubbles of vacuum, whether there is bubbles of vacuum to exist but this practice only can detect, but can't effectively improves the problem of bubbles of vacuum.
