Description
Technical field
The invention relates to a kind of circuit board fixed form of flat-panel screens, particularly a kind of can the protection simultaneously and the fixed form of fixing circuit board.
Background technology
Consult shown in Figure 1ly, the flat-panel screens processing procedure of known technology mainly comprises the following step.In the predetermined position of wanting fixing circuit board 2 of the lateral surface of backboard 1, stick an insulating trip 3 earlier, it is to cause short circuit for fear of the backboard 1 of circuit board 2 contacting metal systems or foreign object.Then light tube group and light-guide device are arranged in the backboard 1, are assembled into module 4 backlight.Simultaneously, paste in liquid crystal panel 5 after the blooming pieces such as polaroid, following polaroid and diffusion sheet, be electrically connected liquid crystal panels 5 and circuit boards 2 with soft arranging wire 6.Then liquid crystal panel 5 is inserted in the module 4 backlight, with side frame 7 in conjunction with liquid crystal panel 5 and module backlight 4.Circuit board 2 and soft arranging wire 6 around to the backboard 1 of module 4 dorsal parts backlight, and are locked circuit board 2, screening glass 9 on backboard 1 with most screws 8.The process of aforementioned attaching insulating trip 3 all quite expends man-hour with the process that locks screw 8, screening glass 9.In addition, though 2 protected 9 protections of circuit board, the side of circuit board 2 is not complete crested, and particularly circuit board 2 has partly or entirely to be open state towards a side of backboard 1 zone line especially.Therefore, when flat-panel screens was erected, the foreign material on the backboard 1 along backboard 1 surface, fell on the circuit board 2 easily, caused circuit board 2 short circuits to be lost efficacy.
No. 7365812 patent cases of U.S. Pat propose a kind of flat-panel screens, and it utilizes the support rib to make circuit board not contact backboard, and with support protrusion portion locating circuit board, makes circuit board not at the backboard top offset.The screening glass that last ambroin is made is covered in circuit board, and screening glass pastes with the glue material and showing on the module, simultaneously with screening glass protection and fixing circuit board.Yet in the US73658512 patent case, circuit board still is an open state towards a side in zone between backboard, therefore when flat-panel screens is erected, foreign material is fallen on the circuit board, causes the circuit board short circuit to be lost efficacy.
Summary of the invention
One object of the present invention is to provide a kind of flat-panel screens, and described flat-panel screens has a flexible insulation sheet, can the Fast Installation circuit board and the insulation protection of circuit board is provided.
For reaching above-mentioned purpose, a kind of flat-panel screens of the present invention comprises and shows module, side frame, backboard, flexible insulation sheet and circuit board.Side frame is around the demonstration module, and the backboard correspondence is arranged at the demonstration module.Flexible insulation sheet has first fixed part, covering part and second fixed part, and wherein first fixed part sticks on the backboard, and covering part is disposed at first fixed part top.Second fixed part extends from covering part, and sticks on the side frame.Circuit board is arranged between first fixed part and the covering part, and sticks in first fixed part and covering part,, and coats and the holding circuit plate with flexible insulation sheet in flexible insulation sheet so as to fixing circuit board.
Another object of the present invention provides a kind of fixing means of circuit board.
The fixing means of a kind of circuit board provided by the invention, in flat-panel screens, this method is pasted the part of flexible insulation sheet earlier on backboard in order to fixing circuit board, then places circuit board on flexible insulation sheet.At last that flexible insulation sheet is folding towards side frame, with covering board, and another part of pasting flexible insulation sheet is on side frame.Wherein, paste circuit board on flexible insulation sheet, with fixing circuit board, and with flexible insulation sheet coating and holding circuit plate.
Flexible insulation sheet also can be the combination of one first lamellar body and one second lamellar body except that can be integrally formed.
The fixing means of a kind of circuit board that the present invention proposes, in flat-panel screens, this method is pasted the part of first lamellar body earlier on backboard in order to fixing circuit board, then places circuit board on first lamellar body.Overlap second lamellar body on first lamellar body, at last that second lamellar body is folding with covering board towards side frame, and another part of pasting second lamellar body is on side frame.Wherein, paste circuit board on first lamellar body or second lamellar body, with fixing circuit board, and with flexible insulation sheet coating and holding circuit plate.
Effect of the present invention is, by folding and paste flexible insulation sheet, and both fixing circuit boards apace.And the two side faces of circuit board and at least dual side-edge coated by flexible insulation sheet, therefore, can effectively avoid foreign object contact circuit plate, strengthen protection effect to circuit board.
