Description

Technical Field

[0001] The utility model relates to a polarizer, more specifically, to a polarizer protective film with an identification mark. Background Art

[0002] Usually, after the LCD module is assembled, a protective film is attached to the polarizer to prevent the LCD module from being contaminated by dirt or dust before it reaches the customer. At the customer's end, this protective film needs to be torn off, but because the material of the protective film is transparent and the visual distinction from the module is not obvious, the customer may miss to tear off the protective film, causing problems with the subsequent products.

[0003] Chinese utility model patent document CN205809464U discloses a polarizer protective film removal device and a polarizer protective film removal tape, and the technical solution is as follows: In the first aspect, a polarizer protective film removal tape is provided, and the polarizer protective film removal tape includes a hollow area and a non-hollow area located around the hollow area, and the area of ​​the hollow area is greater than or equal to the area of ​​the display area of ​​the display panel with the polarizer protective film. The hollow area is a rectangular area; the non-hollow area is an annular area. The inner ring and the outer ring of the annular area are both rectangular, and any side of the inner ring is equidistant from the corresponding side of the outer ring. The width of the annular area is 10 mm. In the second aspect, a polarizer protective film removal device is provided, the device includes the polarizer protective film removal tape described in the first aspect, and the device also includes: a carrier and a pressing component, the carrier is used to carry a display panel with a polarizer protective film; the pressing component is provided with the polarizer protective film removal tape, and the non-hollow area of ​​the polarizer protective film removal tape adheres to the polarizer protective film located in the peripheral area of ​​the display panel under the pressing force of the pressing component. The carrier is provided with a raised structure on one side of the display panel, and the raised structure is in contact with the peripheral area. The cross-section of the raised structure is a rectangle, and the width of the rectangle is greater than or equal to the width of the peripheral area. The width of the rectangle is 10 mm. The raised structure is a layered structure made of rubber, sponge, fiber cloth or carbon fiber. The raised structure and the carrier are an integral structure. The pressing component is a roller.

[0004] Obviously, the patent mainly involves the polarizer protective film removal tape, which prevents the display area of ​​the display panel from being affected by excessive pressure from the pressing component, or the polarizer protective film from being unable to be removed due to too little pressure, thereby improving the reliability of removing the polarizer protective film. This solution cannot solve the problem of the existing protective film being missed.

The non-adhesive layer of the polyester film is an antistatic layer formed by a high molecular conductive polymer.The polyester film adhesive layer is further laminated with a release film.
