Abstract
The utility model discloses a liquid crystal displayer and a connecting structure thereof. The liquid crystal displayer and the connecting structure thereof are used for connecting a flexible printed circuit (PFC) or an integrated circuit (IC). The connecting structure comprises a glass substrate, a metal grid, an insulating protecting layer and an indium tin oxid (ITO) layer, wherein the glass substrate, the metal grid, the insulating layer and the ITO layer are attached sequentially. The ITO layer is connected with the metal grid in an electric mode. The middle area of the metal grid is hollow. In the middle hollow area of the ITO layer, the ITO layer is directly attached on the glass substrate to form a transparent view finder. The utility model further provides the corresponding liquid crystal displayer. The technical scheme includes that the liquid crystal displayer and the connecting structure thereof enable the density and state of conducting particles in an anisotropic conductive adhesive (AFC) bonding area to be presented clearly through the transparent view finder. Detecting people can detect and affirm bonding effects of an AFC intuitively. Detecting efficiency and detecting precision are very high.

Background technology
Flexible PCB (Flexible Printed Circuit, FPC) is that make take polyimide or mylar as base material a kind of has height reliability, excellent flexual printed circuit board (PCB).In the production run of liquid crystal display, by anisotropic conductive film (Anisotropic Conductive Film, ACF) and hot bonding technique, FPC is tied on the FPC pin of syndeton of liquid crystal display.As depicted in figs. 1 and 2, the syndeton of liquid crystal display comprises the glass substrate 101 of fitting successively, metal gates 102, and insulating protective layer 103 and tin indium oxide ITO layer 104, ITO layer 104 is electrically connected with metal gates 102 by equally distributed a plurality of via holes 105.
The method of judging ACF binding effect is, observes the impression of conducting particles from the glass substrate back side, and general conducting particles number more multilist shows that to engage effect better, if but conducting particles too assemble or break and also may cause short circuit phenomenon.In the actual production, the testing staff is difficult to fast and accurately the ACF bonding effect to be detected affirmation, inefficiency and cause easily various erroneous judgements.
The utility model content
The utility model embodiment provides a kind of liquid crystal display and syndeton thereof, to solve the difficult technical matters that detects of ACF bonding effect in the prior art.
A kind of syndeton of liquid crystal display; be used for connecting flexible PCB FPC or integrated circuit (IC); this syndeton comprises the glass substrate of fitting successively; metal gates, insulating protective layer and tin indium oxide ITO layer, described ITO layer is electrically connected with described metal gates; the zone line hollow out of described metal gates; at the zone line of this hollow out, described ITO layer directly is fitted on the described glass substrate, forms transparent picture window.
A kind of liquid crystal display comprises aforesaid syndeton.
The utility model adopts the zone line hollow out with metal gates, zone line in this hollow out, directly be fitted in the ITO layer on the glass substrate, form the technical scheme of transparent picture window, so that density and the state of the conducting particles in ACF binding zone are presented clearly, the testing staff can pass through this transparent picture window, intuitively the ACF bonding effect is detected affirmation, and detection efficiency and accuracy rate are all higher.
