An outer pin pressing area of ​​a panel

Abstract

The invention discloses an outer pin pressing zone of a face plate. The outer pin pressing zone comprises a TFT first cutting line, a first shorting stub assembly, a first group of binding terminals, a TFT second cutting line, a second group of binding terminals and a display zone, wherein the first shorting stub assembly, the first group of binding terminals, the TFT second cutting line, the second group of binding terminals and the display zone are sequentially arranged starting from the TFT first cutting line from outside to inside, the first shorting stub assembly and the first group of binding terminals are connected through a first metal wire, the first group of binding terminals and the second group of binding terminals are connected through a second metal wire, and meanwhile a connecting unit is added between the TFT second cutting line and the second group of binding terminals. By the adoption of the outer pin pressing zone, a conventional-frame face plate and a narrow-frame face plate can be tested by adopting a conventional Cell lighting-on mode, and accordingly the face plate manufacturing cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of thin film transistor liquid crystal display (TFT-LCD), in particular to an Out Lead Bonding (OLB) area of ​​a panel. Background technique [0002] In the market, LCD panels all have a bezel. According to the width of the bezel, the panels are divided into narrow bezel panels and regular bezel panels. Narrow bezel panels are a very important trend in current panel design, but regular bezel panels still occupy In a certain market, panels with different frame specifications will coexist in the market for a foreseeable period of time. [0003] figure 1 It is a schematic diagram of the panel frame, which can be a TFT-LCD panel or an OLED panel. Take the TFT-LCD panel as an example, such as figure 1 , the entire panel includes two substrates, namely a TFT substrate 13 and a CF substrate 12, with a display area 11 in the middle. When the panel is working normally, the display area 11 is responsible for...

Problems solved by technology

[0004] like figure 2 As shown, the left side is the status of the panel before the Cell cutting process. Different products are completely the same at this stage, including the display area 11, the first TFT cutting line 131, the CF first cutting line 121, and the TFT second cutting line. Line 132, CF second cutting line 122, during Cell cutting process, cut along the different cutting lines designed in advance, just can obtain the product of two kinds of different frames, i.e. conventional frame panel (refer to figure 2 top right) and narrow bezel panels (reference figure 2 Bottom right), in the traditional design, two sets of masks are required for products with two different borders. Take the 4Mask TFT substrate as an example, when the border of the panel is changed, four masks need to be modified at the same time, resulting in higher product cost high
