Abstract:
A display device includes a display panel and a window coating layer disposed directly on an upper surface of the display panel. The window coating layer includes a first region which has an increasing elastic modulus in a direction from the display panel toward the window coating layer.
Abstract:
A flexible display device is disclosed. In one aspect, the display device includes a substrate, a display unit formed over the substrate and a filler formed over the substrate and the display unit. An encapsulation substrate is formed over the encapsulation substrate, and a barrier layer is formed over the encapsulation substrate. The encapsulation substrate includes a base layer and a plurality of protrusions formed over a first surface of the base layer and spaced apart from each other. The barrier layer is formed over the first surface so as to cover the plurality of protrusions and a portion of the base layer exposed between the plurality of protrusions, and the first surface faces the display unit.
Abstract:
A display apparatus includes a display panel including a display element, a first film comprising an elastomeric material and disposed on the display panel, the first film having a first thickness, a first adhesive layer disposed on the first film, the first adhesive layer having a second thickness, and a second adhesive layer disposed between the display panel and the first film and having a third thickness equal to or greater than the second thickness of the first adhesive layer.
Abstract:
Disclosed is a display device including a display module that has at least one folding area, a first film disposed on the display module and having a first modulus, a second film disposed on the first film, being farther from the display module than the first film, and having a second modulus less than the first modulus, and a third film disposed on the second film, being farther from the display module than the second film, and having a third modulus less than the second modulus. The third modulus is equal to or less than about one-sixth of the first modulus.
Abstract:
An electronic apparatus includes an electronic panel foldable together with a window; and a first functional layer and a second functional layer each foldable together with the window and the electronic panel. The second functional layer is disposed farther from the window than the first functional layer, and has a thickness in a range from about 30 micrometers to about 50 micrometers and a modulus in a range from about 3 gigapascals to about 8 gigapascals, and the first functional layer is disposed closer to the window than the second functional layer, and has both a thickness equal to or greater than that of the second functional layer, and a modulus less than that of the second functional layer.
Abstract:
A window for a display device includes: a film having flexibility; and at least one coating layer disposed on the film. As tensile stress acting on the film increases, the film is elastically deformed in a first range of strains of the film and plastically deformed in a second range of strains of the film greater than the first range, the first and second ranges being defined by a relationship between the tensile stress and a strain of the film in accordance with the tensile stress. The film has a yield strain in a third range from about 1.9% to about 2.25%, and the yield strain is defined as the strain of the film when a yield stress of the relationship in the first range is applied to the film.
