ADHESIVES TO REPLACE INK STEP BEZELS IN ELECTRONIC DEVICES
The present invention is a two-part adhesive layer including a first, optically clear adhesive composition and a second, light-blocking adhesive composition substantially surrounding the first, optically clear adhesive composition.
POLARIZING PLATE AND OPTICAL DISPLAY APPARATUS COMPRISING THE SAME
A polarizing plate and an optical display apparatus including the same are provided. A polarizing plate includes a polarizer and a protective film stacked on at least one surface of the polarizer, and the polarizer includes a hydrophobic polyvinyl alcohol resin, the polarizer has a surface roughness (Ra) of about 10 nm or less on a surface thereof facing the protective film, and the polarizing plate has a maximum metal ion-infiltration length of about 400 μm or less between the polarizer and the protective film when metal powder-containing pastes are deposited on a surface of the polarizing plate in a thickness direction thereof and left at 60° C. and 95% relative humidity (RH) for 240 hours.
FLEXIBLE DISPLAY APPARATUS
A flexible display apparatus includes a display unit, a first adhesive film on the display unit, an optical film on the first adhesive film, a second adhesive film on the optical film, and a window film on the second adhesive film, and the second adhesive film has a higher modulus than the first adhesive film at −20° C. to 25° C.
Method and apparatus for continuously producing optical panel assemblies
A method of producing an optical panel assembly including the polarizing film in a continuous manner by laminating a polarizing film to a surface of a rectangular-shaped optical panel, is disclosed. The polarizing film is formed by performing a step of subjecting a laminate including a continuous web of a thermoplastic resin substrate and a PVA type resin layer formed on the substrate, to a 2-stage stretching consisting of a preliminary in-air stretching and an in-boric-acid-solution stretching, to reduce a thickness of the PVA type resin layer to 10 μm or less, and a step of causing a dichroic material to be absorbed in the PVA type resin layer.
FUNCTIONAL LAMINATED FILM
Provided is a functional laminated film having a functional layer formed by dispersing functional materials in a binder, in which the functional laminated film can inhibit generation of bubbles in the functional layer, and can prevent the functional material from being deteriorated by water or oxygen. The functional layer is formed by dispersing functional materials in a binder, and the binder is formed by polymerizing monomers. The monomers include 50% by mass or more of monomers X having a molecular weight of 100 to 1,500 with respect to the total mass of the monomers, and the gas barrier performance of a gas barrier film is 0.005 [g/(m.sup.2.Math.day)] to 0.8 [g/(m.sup.2.Math.day)].
Copolyesters plasticized with polymeric plasticizer
Polyester-based films contain certain copolyesters (A) and polyester plasticizers (B). The copolyesters (A) may be selected from those in which the force required to stretch a film of the copolyester (A) by itself, from 2× to 5×, increases by less than 200%. The polyester plasticizers (B) have a weight-average molecular weight of 900 to 12,000 g/mol, and contain (i) a diol component comprising residues of diols having 2 to 8 carbon atoms, and (ii) a diacid component comprising residues of dicarboxylic acids having 4 to 12 carbon atoms. These polyester-based films are particularly useful for preparing ultra-thin LCD or OLED polarizers, because they can be stretched very thin with a high stretch ratio at lower temperatures.
SUPPORT FILM LAYER AND FLEXIBLE DISPLAY PANEL
The present application discloses a support film layer and a flexible display panel. By periodically arranging at least one elliptical hollow structure and a plurality of shuttle-shaped hollow structures in a bending region of the support film layer, stress concentrations in the bending region can be weakened, which is beneficial to increase a bending lifespan of the support film layer. The present application can improve an overall ductility of the flexible display panel, increase a bending performance of the flexible display panel, reduce a risk of peeling and fracture between film layers, and increase production yields of products.
Display device including bonding member
A display device includes a display panel including a front surface and a second surface which is opposite to the front surface; a front laminated structure attached to the front surface of the display panel; and a rear laminated structure attached to the second surface of the display panel. Each of the front laminated structure and the rear laminated structure includes a bonding member, and an average modulus of the bonding member of the front laminated structure is smaller than an average modulus of the bonding member of the rear laminated structure.
Polymer resin, window module including the same, and display apparatus including the same
A window module including a window, a first print layer, an ink layer, and a protective layer covering the ink layer. The protective layer includes a polymer resin polymerized from monomers including a first monomer which is an acrylic monomer substituted with a hydroxy group, a second monomer having an epoxy group, and at least one of a third monomer having a substituted or unsubstituted phenyl group or a fourth monomer which is an acrylic monomer having a substituted or unsubstituted bicyclic alkyl group, and thus, has excellent durability, chemical resistance, and abrasion resistance.
ELECTRONIC DEVICE INCLUDING DISPLAY
