Description
Technical field
The present invention relates to a kind of LCD, be meant especially and a kind ofly on the outer frame member of LCD, dispose fixture, be used for fixing the LCD of the connector between the deflection P.e.c. and printed circuit board (PCB) in the LCD.
Background technology
Generally speaking, as shown in Figure 1, existing LCD 100 comprises a panel of LCD 20, a backlight module 60, a metal framework 10 and a shell spare 70.Panel of LCD 20 has a plurality of winding carrying encapsulation 26, one X printed circuit board (PCB)s 22 and a Y printed circuit board (PCB) 24.Panel of LCD 20 mat winding carrying encapsulation 26 will be controlled and drive signal and be delivered to panel of LCD by two printed circuit board (PCB)s 22 and 24.X printed circuit board (PCB) 22 and Y printed circuit board (PCB) 24 are folded to backlight module 60 back (shown in arrow among the figure).Backlight module 60 comprises a fluorescent tube, a reflectance coating, a light guide plate and an optical thin film (not shown), is used to make light directive panel of LCD 20 equably.Shell spare 70 is used to carry backlight module 60, and is added on panel of LCD 20 and the metal framework 10.For example, United States Patent (USP) has promptly disclosed this type of LCD No. 6380998, and its title is " having LCD backlight ".As shown in Figure 2, in the assembling process of LCD 100, X printed circuit board (PCB) 22 and Y printed circuit board (PCB) 24 need to be electrically connected mutually.Therefore, a flexible printed circuit 28 is used to be electrically connected X printed circuit board (PCB) and Y printed circuit board (PCB) 24.Generally speaking, flexible printed circuit 28 common mat welding or a connector are connected to X printed circuit board (PCB) 22 or Y printed circuit board (PCB) 24.The major defect of welding connecting mode has 3: 1, belong to back-end process, use the possibility of welding automatically not high.2, be easy to generate dirty and the surface LCD of making dirty.3, the plumbous processing of tin is difficult for.With regard to the connector connected mode, shown in Fig. 2, Fig. 3 a and Fig. 3 b, two connectors 30 and 40 are respectively applied for flexible printed circuit 28 are electrically connected to X printed circuit board (PCB) 22 and Y printed circuit board (PCB) 24.Generally speaking, the connector 40 on the X printed circuit board (PCB) 22 generally inserts with horizontal direction, has long engagement travel, has preferable mechanical property.But the connector 30 on the Y printed circuit board (PCB) 24 generally is a vertical direction to be inserted, and is subject to the thickness of LCD 100, and the stroke of its engagement is short, is easy to become flexible or come off.More specifically, connector 30 has a male joint or plug end 34 and a female joint or socket end 32.Plug end 34 is placed on the Y printed circuit board (PCB) 24, and socket end 32 is placed in flexible printed circuit 28.Plug end 34 and socket end 32 engage mutually, are used to be electrically connected flexible printed circuit board 28 and Y printed circuit board (PCB) 24.Yet, because the plug end 34 of connector 30 is to insert the socket end 32 from vertical direction, therefore the engagement travel of connector 30 can be subjected to the restriction of the thickness of LCD 100, this makes the plug end 34 of connector 30 firmly to mesh or to be sticked in the socket end 32, causes flexible printed circuit 28 by breaking away from the Y printed circuit board (PCB) 24.In order to improve this shortcoming, prior art provides an adhesive tape, sticks on connector 30 and the metal framework 10.This adhesive tape not only increases manufacturing cost, also increases process time.
Summary of the invention
The objective of the invention is, a kind of LCD is provided, an one-body molded fixture is used for fixing the connector between flexible printed circuit and the printed circuit board (PCB) on the metal framework of LCD.
The objective of the invention is to realize: a kind of LCD by following technological means, comprise a panel of LCD, a backlight module and a metal framework, it is characterized in that: panel of LCD includes first and 1 second printed circuit board (PCB) that is electrically connected to panel of LCD, a flexible printed circuit, one flexible printed circuit is electrically connected to second connector of second printed circuit board (PCB) with first connector that is electrically connected to first printed circuit board (PCB) perpendicular to the residing in-plane of panel of LCD and with flexible printed circuit; But the backlight module throw light is to panel of LCD; The metal framework that is used to hold panel of LCD and backlight module comprises a fixture, the integrally formed manufacturing of metal framework and fixture, and fixture can prop up first connector with respect to the metal framework distortion.
The fixture mat bending of described LCD props up first connector, and fixture is semi-circular.But fixture also nationality reverses and props up first connector, and fixture also can be square.
The invention has the advantages that: 1, the integrally formed manufacturing of fixture and metal framework, metal framework and fixture generally are by the flexible material manufacturing, therefore after flexible printed circuit is fixed on the circuit board of LCD from the direction of vertical liquid crystal display through connector, the fixture deformable prevents by this that to prop up connector connector breaks away from from circuit board.2, integrally formed according to fixture of the present invention and metal framework, the manufacturing cost of unlikely increase LCD and the assembling man-hour.
