Abstract
The invention discloses a manufacturing method of an LCM (Liquid Crystal Module). The manufacturing method comprises the processes that an anisotropic conductive adhesive is attached on an LCD mainboard after the LCD mainboard is cleaned; a circuit pin of a flexible circuit board with a plurality of drive chips and an ITO (Indium Tin Oxide) electrode pin on the LCD mainboard are welded together and cleaned; the flexible circuit board is electrically connected with the LCD mainboard; a polarizer is attached on the two sides of the LCD mainboard; after a semi-finished product is electrically connected with a backlight board circuit, an upper metal frame and a lower metal frame are mounted to fix the LCM. The manufacturing method further comprises the process that a plurality of mean field ring structures are arranged on the flexible circuit board to prolong the service life of the flexible circuit board before the circuit pin of the flexible circuit board and the ITO electrode pin on the LCD mainboard are welded. The craft process is simple, the LCM manufactured by using the method guarantees the excellent display effect and the excellent transmission of light, the electrostatic produced in the production and manufacturing processes is effectively eliminated, and meanwhile, the service life is prolonged with the use of the mean field ring structure.
Description
Technical field
The present invention relates to technical field of liquid crystal display, relate to a kind of manufacture method of LCM liquid crystal display module specifically.
Background technology
LCM is that a kind of LCD of excellent performance shows module or perhaps Liquid Crystal Module, and it is by liquid crystal display device, web member, controls to wait peripheral circuit, PCB, backlight, the assembly that structural member etc. are assembled together with driving.
LCM provides the LCD display driver interface of standard for user, and user carries out operation according to interface requirement and correctly shows to control LCD.LCM is a kind of LCD product of high integration, and to small size LCD display, LCM can be connected with various microcontroller (such as single-chip microcomputer) more easily; Show the LCD of large scale or colour, generally can take the quite most resource of control system or cannot realize controlling at all, process data volume is huge.LCM product can effectively solve the problem.
Summary of the invention
In view of the defect that prior art exists, the object of the invention is the manufacture method that a kind of novel LCM will be provided.
To achieve these goals, technical scheme of the present invention:
A manufacture method for LCM liquid crystal display module, is characterized in that: comprise following technique:
