Background technology
Liquid crystal display, that is, LCD (Liquid Crystal Display), is the display device of planar ultra-thin, it is by certain
Colour or the monochrome pixels composition of quantity, are positioned in front of light source or reflecting surface.
The displaying principle of LCD is the filling liquid crystal material between two blocks of parallel-plates, is changed by voltage in liquid crystal material
Part comes column-shaped condition, to achieve the purpose that shading and the printing opacity image deep mixed, in picturesque disorder to show, and only
The filter layer of three-primary colours is added between two pieces of tablets, so that it may realize and show coloured image.Monochromatic LCD is almost moved back at present
Go out laptop market, and colored LCD still sustainable developments.Color LCD is mainly divided into two kinds of STN and TFT, wherein TFT again
(Thin Film Transistor) LCD, also known as active electric crystalline substance thin film transistor liquid crystal display screen, that is, by many people
The very color liquid crystal display being commonly called as;DSTN (Dual-Scn Twisted Nematic) LCD, i.e., double scanning liquid crystal displays, are
A kind of display mode of STN LCD, has logged out market now.
The electric signal component of liquid crystal display is mainly made of backlight circuit and display circuit, and wherein display circuit is used for
Transmission liquid crystal panel pixel drives required electric charge and control signal, mainly utilizes printed circuit board, that is, PCB (Printed
Circuit Board) transmit, while need to be through the IC i.e. Driver IC of overdriving by electric charge and control signal transmission to liquid crystal surface
In plate.Generally one end connection liquid crystal panel of i.e. Driver IC, other end connection PCB.Usually by liquid crystal panel adjacent two
Side is divided into Gate ends and Source ends, and the Driver IC at Gate ends are linked to the Gate ends of liquid crystal panel, is responsible for each row
The switch of transistor, when scanning, once open the transistor of a permutation, the Driver IC at Source ends be linked to liquid crystal panel it
Gate ends, when transistor is opened, the Driver IC at Source ends can be line by line by control brightness, the control of grayscale, color
The passage that voltage is formed through transistor Source ends, Drain ends enters in the picture element of liquid crystal panel.Thus in manufacture liquid crystal
, it is necessary to which liquid crystal panel, Driver IC and PCB three are pressed successively during display screen.
Bonding processes are broadly divided into two processing procedures, i.e. precompressed and this pressure, and precompressed is the processing procedure before this pressure.Precompressed exists
The both ends join domain of Driver IC stamps conductive adhesive film, then applies certain pressure again and is positioned at Driver IC and leads
On electric glued membrane;This pressure will Driver IC after positioning apply after certain pressure with PCB or liquid crystal panel Joint.
It is intended to use the draw frame machine for drawing Driver IC in this pressure or precompressed processing procedure, due to Driver IC
Size it is smaller, only several millimeters mostly, this just there are certain requirements the precision of draw frame machine, and existing draw frame machine is adjustable
The free degree of section is less, thereby results in limitation of the existing draw frame machine due to the free degree without adapting to different dimensions
