Abstract
The utility model discloses integral type back glue, which belongs to back glue for manufacturing a liquid crystal display (LCD) and a touch panel. The integral type back glue comprises a frame-shaped glue body and protective layers arranged on two faces of the glue body. The protective layers arranged on two faces of the glue body are whole-face release films, a ripper is arranged on one layer of the release films, and the bonding force between the release film with the ripper is larger than that between the frame-shaped glue body and the other layer of the release films. Pollutant is prevented from being transferred onto the touch panel during the bonding process of the touch panel and the LCD. Needed materials and manufacture method are simple. The back glue is supported by the whole-face release films, thereby well maintaining the structure of the frame-shaped glue body and facilitating adhering with the touch screen.
Description
Technical field
The utility model belongs to the gum of making liquid crystal display, touch-screen.
Background technology
Nowadays, the development of handset touch panel and liquid crystal display more and more obtains popular popularizing at present.
Touch-screen (Touch Panel) is meant when finger touches Sensor; Have analog signal output; Convert analog signal into computingmachine acceptable digital signal by unit; Integrate each assembly compiling via the touch-control driver in the computingmachine again, on screen, demonstrate the position of being touched by display card output screen signal at last.
Divide into the different of sensing form according to structure: resistive touch screen, capacitive touch screen, acoustic wave touch-screen, optical profile type touch-screen, electromagnetical type touch screen.
The most general use at present for utilizing the unit of USB port transmission; The function of unit is that the analog signal that Sensor is sent converts digital signal into; Go to differentiate via driver again; Utilize the various Design and Features increases of touch-control driver can accomplish various variations, for example present the multi-lingual client of convenience and use, increase handwriting identification function, the support of multi-screen system, support of computer game or the like.
For touch-screen (Touch Panel) is assembled with LCD fast; Used a kind of double sticky tape bonding at touch-screen (Touch Panel) with LCD is middle; Owing in carrying out operating process, cause dust easily; Various source of pollution such as fingerprint, this source of pollution can directly be transferred to above the touch-screen (Touch Panel).
Prior art is when handling the problems referred to above; Respectively covered two-layer whole dicing film on shaped as frame colloid two sides; And be provided with whole the dicing film that band tears hand; But when tearing wherein one deck dicing film, tend to tear another layer dicing film and shaped as frame colloid, just do not reach when operation and make pollution can not drop to the effect on the touch-screen (Touch Panel).
The utility model content
The purpose of the utility model provides a kind of integral type gum, prevents when touch-screen (Touch Panel) bonds with LCD, pollutent to be transferred to above the touch-screen (Touch Panel).
A kind of integral type gum; The resist that comprises shaped as frame colloid and colloid two sides; The resist on described colloid two sides is whole a dicing film; Wherein one deck dicing film is provided with and tears hand, and said band tears dicing film and the shaped as frame colloidal cohesive force of the hand cohesive force greater than shaped as frame colloid and another layer dicing film.
Tear at described whole band and also to be provided with protective membrane on the hand dicing film.
Described protective membrane tears the cohesive force of the cohesive force of hand dicing film greater than shaped as frame colloid and another layer dicing film with band.
For achieving the above object, the integral type gum of this programme is specifically related to content and comprises: PET dicing film, PE protective membrane, double sticky tape.
The involved PET that gets in the PET dicing film is meant one deck polyethylene terephthalate in the such scheme, and English Polythylene terephthalate by name is called for short PET.So-called PET dicing film is meant on the polyethylene terephthalate surface one deck silicone oil is set, and lets it can show extremely light and stable off-type force for various organic pressure sensitivity glue.
Related PET dicing film among the present invention, its thickness can be done corresponding adjustment according to demand, 0.05mm for example, 0.075 mm, 0.1 mm etc.
PE in the such scheme in the involved PE protective membrane is meant sealed polyethylene plastic, and full name is Polyethylene.So-called PE protective membrane is meant and on sealed polyethylene plastic, is coated with the last layer glue paste, lets it can be attached to the surface that will protect product.PE protective membrane biggest advantage be protected product in process for processing, transportation, store with use in not contaminated, corrosion scratches, and protects original bright and clean glossy surface, thus the quality and the market competitiveness of raising product.
PE protective membrane thickness related in the utility model also can be done corresponding adjustment as required, and for example used thickness is 0.06 mm in the utility model, 0.14 mm etc.
Related double faced adhesive tape is meant the adhesive tape that is used between bonding touch-screen (Touch panel) and the LCD in the such scheme; Related adhesive tape uses a kind of base material in the middle of being in this programme; On base material, be coated with the last layer glue paste, make it possess adhesive effect, because it is bonding to relate to the product needed two sides among the present invention; So adhesive tape is referred to as double sticky tape for all to coat glue paste on the base material two sides.Relating to the classification of double faced adhesive tape intermediary base material in this programme has: PET base material, cotton base material, non-woven fabrics base material etc., the glue paste that on base material, is coated with in this programme is divided into two types: acrylic glue (Acrcily) and silica gel (Silicon).
Since use in the utility model be acrylic glue, so above the PET dicing film that relates to only told about the silicone oil dicing film, in fact also having a kind of dicing film is fluorine element dicing film, is applicable to that glue paste is that silica gel is serial.
Beneficial effect:
(1) prevents when touch-screen (Touch Panel) bonds with LCD, pollutent to be transferred to above the touch-screen (Touch Panel).
(2) and required material, making method simple.
(3) gum has whole dicing film to support, and can be good at keeping frame type colloidal structure, makes things convenient for the applying touch-screen.
