Detailed Description
In order that the utility model may be readily understood, a more complete description of the utility model will be rendered by reference to the appended drawings.
The utility model provides a solve cotton layered structure of bubble, refer to fig. 1, including bubble cotton body 10, one side of bubble cotton body 10 is used for pasting with the display screen, and the opposite side of bubble cotton body 10 is used for pasting with being shaded, and bubble cotton body 10 pastes between display screen and being shaded, can absorb the deformation that comes from being shaded in order to reduce the uneven problem of display screen luminance that the deformation of display screen leads to.
Referring to fig. 1 and 2, the foam body 10 is a spliced double-sided adhesive tape 11 with a four-corner spliced structure, and the foam body 10 is formed by splicing four double-sided adhesive tapes 11 in a shape of a Chinese character kou. The both sides of foam body 10 all are attached with from the type membrane, because foam body 10 is the concatenation of four corners and forms, the four corners department of foam body 10 connects unstably to make when tearing from the type membrane, the concatenation department in foam body 10 four corners can produce effort, carries out the layering with foam body 10 easily, consequently, foam body 10 is used for and is provided with non-adhesive area 21 for foam body 10's four corners department from the type membrane of attached one side of display screen.
Referring to fig. 1, the foam body 10 has adhesive on both upper and lower sides for bonding with a display screen and backlight, respectively. The foam body 10 is provided with a weak adhesive 12 on the side where the display screen is adhered, and a strong adhesive 13 on the side where the foam body 10 is adhered to the backlight.
Referring to fig. 1 and 3, the release films on two sides of the foam body 10 are a first release film 20 and a second release film 30, the first release film 20 is located on one side of the weak adhesive 12 on the upper side of the foam body 10 away from the foam body 10, and the first release film 20 is used for protecting the weak adhesive 12 which is not adhered to the display screen. The second release film 30 is located at one side of the strong adhesive 13 at the lower side of the foam body 10 away from the foam body 10, and the second release film 30 is used for protecting the strong adhesive 13 which is not adhered to the backlight.
Further, referring to fig. 1, both the side of the first release film 20 facing the weak adhesive 12 and the side of the second release film 30 facing the strong adhesive 13 are adhesive, so that the first release film 20 and the second release film 30 can be adhered to the foam body 10.
Further, referring to fig. 1, the first release film 20 has strong adhesion towards the weak adhesive 12, and the second release film 30 has weak adhesion towards the strong adhesive 13, so that when the first release film 20 has strong adhesion, the first release film 20 may be torn off, and four corners of the foam body 10 may be lifted up to delaminate the foam body 10 due to the weak adhesive 12 of the foam body 10 being adhered to the display screen. Therefore, the four corners of the first release film 20 facing the foam body 10 are provided with non-adhesive areas 21.
Referring to fig. 1 and 3, the non-adhesive area 21 is provided in a rectangular shape, and the non-adhesive area 21 covers the splice of two adjacent double-sided adhesives 11.
