Abstract:
Provided is a flat fluorescent lamp that can emit white light composed of color components with enhanced color purity and/or white light having enhanced brightness and enhanced brightness uniformity. The flat fluorescent lamp includes a front substrate and a rear substrate separated from each other and defining a discharge space therebetween, a discharge gas filled in the discharge space and generating a first ultraviolet (UV) light with a wavelength of 260 nm or less by discharge of the discharge gas, at least a pair of electrodes inducing the discharge of the discharge gas, a second phosphor layer disposed on an inner surface of the rear substrate and including a phosphor excited by the first UV light and generating a second UV light having a wavelength of 200 to 400 nm which is longer than the wavelength of the first UV light, and a first phosphor layer disposed on an inner surface of the front substrate and including a phosphor excited by the first UV light and the second UV light and generating a visible light. Provided are also novel UV light-emitting phosphors excited by vacuum UV light and generating UV light.
Abstract:
Provided is a flat lamp. The flat lamp comprises an upper substrate, a lower substrate, first electrode portions, and second electrode portions. The lower and upper substrates are arranged to face each other with a certain distance and form at least one discharge cell between the upper and lower substrates. A pair of first and second electrode portions is formed in each of the discharge cells on at least one of the upper and lower substrates. Each of the first and second electrode portions includes a plurality of electrodes.
Abstract:
A design for a plasma display panel (PDP). The novel PDP has two separate layers of fluorescent material. One layer of fluorescent material can generate long wavelength from VUV rays and the other fluorescent layer can convert either of VUV or long wavelength ultraviolet rays into visible rays. Such a PDP improves the luminance efficiency by more efficiently using the UV and VUV rays generated during plasma discharge.
Abstract:
A plasma display panel including front and rear substrates facing each other to form a discharge space therebetween; a plurality of address electrodes on an upper surface of the rear substrate; a first dielectric layer covering the address electrodes on the upper surface of the rear substrate; partitions provided on a upper surface of the first dielectric layer to partition the discharge space; a plurality of second dielectric layers provided on a lower surface of the front substrate and extending in a direction perpendicular to the address electrodes; first and second sustaining electrodes provided to be slanted to face each other on both sides of each of the second dielectric layers; a third dielectric layer provided on a lower surface of the second dielectric layers to cover the first and second sustaining electrodes; and a protective layer provided on a lower surface of the third dielectric layer.
