Description

Structure of three-section type tearing release film

Technical Field

The utility model belongs to the technical field of LCM, and particularly relates to a three-section type tearing release film structure.

Background

LCM (LCD Module) it is an LCD display module and a liquid crystal module, and is a component for assembling the LCD display device, the connecting piece, the peripheral circuits for controlling and driving, the PCB circuit board, the backlight source, the structural component, etc., wherein the LCD display module and the PCB circuit board need to be attached with a conductive cloth, the conductive cloth is covered with a release film, and the release film is torn off to attach the conductive cloth on the LCD display module and the PCB circuit board to enhance the ESD resistance of the product.

The traditional release film is generally divided into one or two sections when the LCD display module and the PCB are attached, taking two sections as examples, the first section release film is generally torn off to attach the exposed conductive cloth on the LCD display module, then the second section release film is torn off to attach the rest conductive cloth on the PCB, when the design is limited to attach the PCB, the size of the conductive cloth cannot exceed the size of the PCB, if the size of the conductive cloth exceeds the size, dust is easy to be attached to the PCB or the PCB can be pulled by an turnover disc, so that the PCB is poor in function, and meanwhile, when the release film is arranged into two sections, the conductive cloth is not easy to attach after the release film is torn off, sticky parts can be touched, so that the attaching precision is influenced when the package is attached, and meanwhile, the size of the conductive cloth cannot exceed the size of the PCB and the ESD resistance is not strong.

Disclosure of Invention

The utility model aims to provide a three-section type tearing release film structure so as to solve the problems in the background technology.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a three-section type tears structure from type membrane, includes conductive cloth, conductive cloth covers one deck from type membrane, from type membrane with conductive cloth size is the same, from type membrane separation is from type membrane first section, from type membrane second section, from type membrane third section, from type membrane first section connection corresponding from type membrane first section tear the hand, from type membrane second section connection corresponding from type membrane second section tear the hand, from type membrane third section connection corresponding from type membrane third section tear the hand, from type membrane first section corresponds conductive cloth part pastes on LCD display module assembly, from type membrane second section, from type membrane third section corresponds conductive cloth part pastes on the FPC board.

Preferably, the overall dimension of the second section of the release film is smaller than that of the FPC board, and the added overall dimension of the second section of the release film and the third section of the release film is larger than that of the FPC board.

The utility model has the technical effects and advantages that:

1. through the design of syllogic dyestripping, will earlier from the conductive cloth subsides package that corresponds after tearing of type membrane first section is in after the LCD display module assembly, then will from the conductive cloth subsides package that corresponds after tearing of type membrane second section is in on the FPC board, paste again at last and paste on being shaded the rubber iron from the conductive cloth subsides that the third section of type membrane was torn the hand corresponds, make in the laminating process need not touch conductive cloth viscidity position, laminating precision is higher, and is difficult to be infected with the dust and influence FPC board performance.

2. Because the third section of the release film corresponding to the conductive cloth part exceeds the FPC board during packaging, the release film is adhered to the backlight rubber iron, and the anti-ESD capability of the product is improved, and the problem that the PCB circuit board is pulled when the release film is adhered to the turnover disc is solved.
