Abstract
The utility model discloses a liquid crystal display module (LCM) with flexible flat cable (FFC) suitable for chip on board (COB) test. The LCM module comprises a printed circuit board (PCB), and a thimble connector capable of connecting with a thimble is arranged on the PCB. Due to the fact that the thimble connector is arranged on the PCB, the thimble can be inserted into the thimble connector directly when the COB test is conducted, the COB test is greatly facilitated, test supports are simplified correspondingly, and reliability is improved simultaneously.
Description
Technical field
The utility model relates to field of liquid crystal display, relates in particular a kind of LCM module with the FFC interface, and it can realize carrying out fast the COB test.
Background technology
The LCM module is LCD and shows module or Liquid Crystal Module, and it refers to assembly that the peripheral circuits such as liquid crystal display device, web member, control and driving, PCB circuit board, backlight and other structural member etc. are assembled together.
FFC, be that flexible flat cable is a kind of with PET insulating material and zinc-plated flat copper wire as thin as a wafer, by the new types of data cable that the pressing of high-tech automation equipment production line forms, have softness, arbitrarily bending fold, thin thickness, volume is little, connection is simple, convenient disassembly, easily solve the advantage such as electromagnetic screen.
At present, for the LCM module, when it adopts FFC to carry out the COB test as splicing ear, because FFC winding displacement and the single fillet welded limit, the test connected mode of bad employing thimble when carrying out the COB test, so wiring bothers very much when carrying out the COB test, and testing efficiency is low.
In view of this, the inventor furthers investigate for defects of the prior art, then has this case to produce.
The utility model content
The purpose of this utility model is to provide a kind of LCM module with the FFC interface of the COB of being convenient to test, has wiring with the solution prior art when carrying out the COB test and bothers very much the problem that testing efficiency is low.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of LCM module with the FFC interface of being convenient to the COB test, wherein, this LCM module has pcb board, and offering on this pcb board can be for the thimble connector that links to each other with thimble.
Described thimble connector is that a round directly is the through hole of 2.0mm.
After adopting said structure, a kind of LCM module with the FFC interface that the utility model relates to, it is by establishing the thimble connector, so when carrying out the COB test, can directly thimble be inserted in the thimble connector, greatly facilitate like this COB test, greatly simplified corresponding testing jig simultaneously, improved reliability.
Description of drawings
Fig. 1 is the structural representation with the LCM module of FFC interface that the utility model relates to a kind of COB of being convenient to test.
Among the figure:
Embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
As shown in Figure 1, the LCM module 1 with the FFC interface of a kind of COB of being convenient to test that the utility model relates to, this LCM module 1 has pcb board 11, offers thimble connector 111 on this pcb board 11, this thimble connector 111 can for linking to each other with thimble, be tested thereby carry out COB.
More specifically, described thimble connector 111 is that a round directly is the through hole of 2.0mm.So, a kind of LCM module 1 with the FFC interface that the utility model relates to, it is by being provided with thimble connector 111, so when carrying out the COB test, can directly thimble be inserted in the thimble connector 111, greatly facilitate like this COB test, also greatly simplified simultaneously corresponding testing jig, improved the reliability of whole test.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
Claims (2)
1. the LCM module with the FFC interface of being convenient to the COB test is characterized in that this LCM module has pcb board, and offering on this pcb board can be for the thimble connector that links to each other with thimble.
2. a kind of LCM module with the FFC interface of being convenient to the COB test as claimed in claim 1 is characterized in that described thimble connector is that a round directly is the through hole of 2.0mm.
