Problems solved by technology

When the protective layer 104b does not protrude into the glass substrate 102b, the flexible substrate 106b will produce a stress concentration effect in the area B and be prone to bending damage. At the same time, the flexible substrate 106 in the area B is also lacking the protection of the protective layer 104b. and easily scratched by the sharp edges of the glass substrate 102b
In this way, it will not only affect the quality of the transmission signal, but also lead to the problem of poor picture quality

Embodiment Construction

[0046] Examples of exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings of the present invention.

[0047] Figure 2A It is a schematic partial top view of a liquid crystal display in an exemplary embodiment of the present invention. Figure 2B for further targeting Figure 2A A schematic top view of the flexible substrate 205. Please refer to Figure 2A and Figure 2B The liquid crystal display 200 of this exemplary embodiment includes a display panel 203 having a substrate 202 and a flexible substrate 205 having a protective layer 204 (Protective Layer or Solder Resistor). Wherein, the substrate 202 can be a glass substrate or a quartz substrate, and a plurality of contact pads (Pads) are arranged on it, and can be connected with the flexible substrate 205 by pasting an adhesive film, such as an anisotropic conductive adhesive film (ACF). Metal wires (or conductive pins (Lead)) are electrically connec...

Abstract

The invention relates to a liquid crystal display, which comprises a display panel with a substrate and a flexible substrate with a plurality of leads and a protective layer, wherein the protective layer covers on the leads, and the flexible substrate is jointed together with the substrate by a fit technology; part of protective layer at the joint of the display panel and the flexible substrate is provided with a plurality of first regular or irregular salients; part of first salients extends into the substrate and is overlapped with the substrate to form a plurality of first overlap regions; and part of first salients does not extend into the substrate, and thereby, a plurality of first gaps are formed at the joint of the substrate and the flexible substrate.

Description

technical field [0001] The present invention relates to a bonding technology, and in particular to a bonding technology of a display panel and a flexible substrate. Background technique [0002] In recent years, with the vigorous development of semiconductor technology, portable electronic products and flat panel display products are also emerging. Among the types of flat panel displays, Liquid Crystal Display (LCD) has become the mainstream of display products due to its advantages of low voltage operation, no radiation scattering, light weight and small size. [0003] Generally speaking, the process of liquid crystal display includes a modularized (Modularized) process. The purpose is to combine single modules such as Display Panel, Backlight Module, Driving Circuit and Control Board into a liquid crystal display, which includes edge grinding and chamfer , polarizer attachment (Polarizer Attachment), tape carrier package (Tape Carrier Package, TCP) or flexible substrate ...
