A flat panel display device including a display area where an image is displayed and a non-display area located at an outside of the display area includes bank portions arranged in a pattern in the display area and partitioning a plurality of openings, emission elements located in the openings, dummy bank portions formed in the non-display area and integrated therewith, and a sealing passivation layer having a multi-layered structure of organic films and inorganic films alternately arranged, one organic film being located at an interface directly contacting the emission element and one inorganic film located firstly on an outermost portion of the dummy bank portions when the sealing passivation layer extends from the display area to the non-display area.

Flat panel display device and method thereof

An active matrix electrochromic device array and a method of manufacturing the active matrix electrochromic device array may include a first substrate including a pixel electrode corresponding to each of the pixels, and an electrochromic layer; a second substrate including a counter electrode and a reflective layer arranged on the counter electrode, wherein the first substrate and the second substrate are coupled to each other having a distance therebetween by a partition wall supporting the first substrate and the second substrate; and the partition wall isolates a space between the first substrate and the second substrate with respect to each of the pixels, thereby preventing or reducing an electrolyte filled in the space from being diffused toward a neighboring space.

A foldable display device includes; a plurality of substrates separated from one another by predetermined intervals, a plurality of driving units including at least one driving unit disposed on each of the plurality of substrates, a flexible display unit disposed above the plurality of substrates and including a plurality of pixel electrodes respectively corresponding to the plurality of driving units, and a flexible connection unit disposed between the plurality of substrates and the flexible display unit and which electrically connects the plurality of driving units and the plurality of pixel electrodes.

Foldable display device

A flat panel display device includes a display area in which a desired image is displayed, and a non-display area arranged outside the display area and bordering the display area, and further includes bank portions arranged in a pattern in the display area and partitioning a plurality of first openings, emission elements arranged at the first openings, dummy bank portions formed in the non-display area in substantially a same pattern as the bank portions and partitioning a plurality of second openings, an absorbing material layer for removing oxygen/moisture located at the second openings, and a sealing passivation layer isolating the emission elements from the outside air and including a structure having at least two layers comprising an organic film and an inorganic film deposited alternately. Thus, the emission elements are prevented from being oxidized or corroded by a harmful material, and in a manner that minimizes additional processes.

A panel for a multi-panel display effectively reduces the width of its connecting portion. The panel for a multi-panel display comprises a substrate, a display element mounted on the substrate, a glass cover attached to the substrate, and a recess in the substrate between the display element and an end of the substrate, wherein the glass cover is attached to the substrate within the recess. The panel for a multi-panel display of the present invention reduces the width of the connecting portion so that a high quality continuous screen image formed on two panels can be obtained.

Panel for multi-panel display and method of manufacture

A flat panel display device comprises a substrate, an organic light emitting diode formed on the substrate, an inner stack encapsulating the light emitting diode and comprising at least one organic layer and one inorganic layer, and an outer stack deposited to cover the inner stack and comprising at least two polymer layers and an adhesive and bonding layer disposed therebetween to combine the at least two polymer layers and a polymer heat-curing film disposed at an interface of each of the polymer layers and the adhesive and bonding layer and cured by heat treatment. According to the present invention, the flat panel display device and a manufacturing method for the same reliably seals the organic light emitting device and prevents degradation by permeation of external harmful materials, while providing high flexibility and low manufacturing cost.

An organic light emitting display including an ultraviolet protecting layer and a method of manufacturing the same include a lower substrate; an ultraviolet hardening adhesive formed on the lower substrate; a driving unit and a light emitting unit deposited on the lower substrate and surrounded by the ultraviolet hardening adhesive; an encapsulation layer covering the driving unit and light emitting unit and preventing moisture and oxygen penetration from an outside; an upper substrate arranged on the encapsulation layer facing the lower substrate and fixed by the ultraviolet hardening adhesive; and an ultraviolet ray blocking film formed in a region to block the driving unit and the light emitting unit from being irradiated by UV rays radiated to harden the ultraviolet hardening adhesive. The ultraviolet ray blocking film is disposed in the encapsulation layer or on the upper substrate to protect the driving unit and light emitting unit from ultraviolet rays.

An organic electroluminescent device having an improved structure includes; a duo-bank defining a unit pixel on a substrate, the duo-bank including a first bank and a second bank which are spaced apart from each other, and an organic luminescent material layer formed by inkjet printing a solution containing an organic luminescent material in the unit pixel and a gap between the first bank and the second bank.

Organic electroluminescent device and method of manufacturing the same

An organic light emitting display and a manufacturing method thereof include an improved encapsulation layer. The encapsulation layer of the organic light emitting display includes an organic layer uniformly covering bank portions and light emitting areas on a substrate; and an inorganic layer formed thicker on the light emitting areas than on the bank portions. In the organic light emitting display, the inorganic layer is thick on the light emitting area in which a sealing ability is required and the bank portion is thin in order to provide flexibility. Therefore, the encapsulation layer can be formed more easily compared to an encapsulation layer on a device in which the organic layer and inorganic layer are alternately formed at least 10 times.
