Benefits of technology

The present disclosure provides a liquid crystal display panel and a manufacturing method to solve problems in current technology and optimize the external structure of panels to achieve narrower frames. The invention reduces processes related to gold ball, effectively narrows the external space of a panel, improves product yield, and enhances production efficiency and competitiveness by improving the external structure of display panels.

Problems solved by technology

In TV and commercial display panel markets, narrow frame products have become more popular, and narrowing frame widths of display panels is a very important design issue.
In conventional panels, center positions of transfer pads and gold ball are usually staggered by a distance when manufacturing, so that the two occupy a greater external space, which is very unfavorable for narrowing frames of panels.
In designs of periphery of an entire panel, the total width occupied by the sealing bezel adhesive layer 31 and the gold ball 41 are d1+d2, it is greater than 1 mm in conventional, the width is greater for video wall products, and this will make panel frames difficult to continue to narrow down, which is unfavorable to achieve narrow frame panels.
Existence of this distance will also make it difficult to continue to narrow the display panel frames of VA mode and TN mode.

embodiment 1

[0032]Referring to FIG. 6 to FIG. 8, FIG. 6 is a schematic bonding diagram of a liquid crystal display panel according to an embodiment of the present disclosure. FIG. 7 is a schematic structural diagram of two conducted substrates in a liquid crystal display panel according embodiment 1 of the present disclosure. FIG. 8 is a schematic planar diagram of an external setting of the liquid crystal display panel in FIG. 7.

[0033]As shown in FIG. 6, the liquid crystal display panel comprises a first substrate 61, a second substrate 62, and a liquid crystal layer 63 disposed between the two substrates. The two substrates are paired to form a liquid crystal box. A closed ring pattern of a sealing bezel adhesive layer 64 is formed on surrounding (non-display area) of the liquid crystal display panel by a sealing material (sealant), and the liquid crystal layer 63 is sealed therein. A side bond pad 65 is disposed on one side surface of the liquid crystal display panel which is used to bond a ...

embodiment 2

[0039]Referring to FIG. 9 and FIG. 10, FIG. 9 is a schematic structural diagram of two conducted substrates in a liquid crystal display panel according embodiment 2 of the present disclosure. FIG. 10 is a schematic planar diagram of an external setting of the liquid crystal display panel in FIG. 9. The difference from the embodiment as shown in FIG. 7 is that, in the embodiment, the common voltage signal line on the COF is electrically connected to the CF substrate-side transparent conductive layer (CF-ITO), and meanwhile is connected to the TFT array substrate-side common voltage signal line, so that the driver IC can input common voltage signals into the plane through the CF-ITO and the TFT array substrate-side common voltage signal line at the same time.

[0040]Specifically, a CF substrate 91 includes a first base substrate 911 and a first transparent conductive layer (ITO) 912 disposed on the first base substrate 911. The first transparent conductive layer 912 includes a first com...

Abstract

The present disclosure provides a liquid crystal display panel and a manufacturing method thereof by disposing a side bond pad on sides of a first substrate and a second substrate, and a side of a sealing bezel adhesive layer away from a liquid crystal layer. Wherein, the side bond pad is in contact with a first transparent conductive layer of the first substrate, and a chip on film is bonded to the side bond pad in a side bonding way. It can achieve that a common voltage signal is transmitted from a side of the first substrate to the first substrate, processes relating to gold ball are reduced, and an external space of a panel is effectively narrowed.

Description

FIELD OF INVENTION[0001]The present disclosure relates to the field of liquid crystal display technologies, and more particularly to a liquid crystal display panel and a manufacturing method thereof.BACKGROUND OF INVENTION[0002]In TV and commercial display panel markets, narrow frame products have become more popular, and narrowing frame widths of display panels is a very important design issue.[0003]Thin film transistor-liquid crystal displays (TFT-LCDs) are generally composed of a first substrate, a second substrate, and a liquid crystal (LC) layer disposed between the two substrates. The first substrate and the second substrate are respectively fabricated, the first substrate may be a color film (CF) substrate, the second substrate may be a thin film transistor (TFT) array substrate, and the first and second substrate are paired to form a liquid crystal box. Vertical alignment (VA) mode and twisted nematic (TN) mode are two important liquid crystal display modes. A liquid crystal...
