    Abstract: A single substrate AC and/or DC gas discharge (plasma) display device with hollow shells containing ionizable gas at a predetermined pressure, each shell being positioned on the surface of the substrate or within a substrate cavity, well, or hollow. Each shell is in electrical contact with at least one electrode, typically two, three, or more electrodes. The AC or DC gas discharge within each shell emits photons in the visible and/or invisible range. In one embodiment, photons from the gas discharge within a shell excite a luminescent substance or material such as a phosphor that emits photons in the visible and/or invisible spectrum. The shell may contain the luminescent substance or the substance may be located separately from, but in close proximity to the shell.

An organic electro-luminescent diode is formed on the first substrate. The sealant contains a frit glass and a light-heat converter. The frit glass can reduce the moisture and oxygen transmission rate by preventing the organic electro-luminescent diode from being thermally decomposed during a curing process. Since the two substrates are encapsulated by the frit glass, the lifetime and reliability of the organic electro-luminescence display device can be increased.

  • Patent number: 8692463
    Abstract: A protective film (6) having a high secondary-emission coefficient is formed on a dielectric layer (5) so as to lower the discharge voltage of a plasma display panel. When the protective film (6) is exposed to the air, it will transform or become cloudy, or the secondary-emission coefficient will lower. To prevent this problem, an inert film (60) is formed on the surface of the protective film (6). As the inert film (60), a film of a metal oxide such as SiO2 and a film of a metal such as Tb are simultaneously formed. Thus, an inert film (60) excellent in barrier property against oxygen and water in the air and enabling easy sputtering from near the discharge electrode at the aging step can be obtained. With this, a plasma display panel exhibiting a low discharge voltage can be realized.

    Abstract: A method of manufacturing a flexible display device and a carrier substrate for manufacturing the same are disclosed. In one aspect, the method includes preparing a first release area and a first attachment area around the first surface area on a first surface, attaching a base substrate to the first surface, and forming a display unit on the base substrate corresponding to the first release area of the carrier substrate. The method also includes cutting the area of the base substrate corresponding to the first release area of the carrier substrate so as to include the display unit, and separating the cut base substrate from the carrier substrate. Thus, the carrier substrate and the base substrate may be smoothly combined with each other and separated from each other without an additional mask deposition process. Also, damage to a product that may occur during combination and separation of the substrates may be much reduced.
