Abstract:
An optical film includes liquid crystal layers and adhesive layers. The liquid crystal layers are disposed at a base substrate. Each of the liquid crystal layers reflects light having a first wavelength and transmits light having a wavelength different from the first wavelength. Each of the adhesive layers is disposed between adjacent ones of the liquid crystal layers to combine the liquid crystal layers.
Abstract:
A flat fluorescent lamp includes a first substrate, a second substrate combined with the first substrate to define a plurality of discharge spaces, and a first external electrode formed on the outer surface of the second substrate to cross the discharge spaces. A first region of the second substrate corresponding to an outermost discharge space has a thickness thinner than that of a second region of the second substrate corresponding to remaining discharge spaces not disposed outermost. Thus, the outermost discharge space may have a compensated luminance, thereby improving luminance uniformity of light emitted from the flat fluorescent lamp and display quality of the liquid crystal display device including the flat fluorescent lamp.
Abstract:
The present invention uses at least one array of complex-shaped fibers that contain at least one wire electrode running the length of the glass structure to fabricate a fluorescent lamp. At least one of the complex-shaped fibers has a complex cross-section that forms a channel, which supports a plasma gas. The array of fibers can be composed flat to form a fluorescent lamp or in a cylindrical or conical shaped fluorescent lamp.

A liquid crystal display includes a liquid crystal display panel which has first and second drain lines groups, a control circuit board which has a control unit, a first and second drain drivers groups connected to the corresponding first and second drain lines groups, a back light unit, a metal frame, and a shield member which shields against EMI. Both of the first and second drain drivers groups are arranged at a same peripheral side of the liquid crystal display panel. The control unit supplies first and second signals to the drain drivers groups via flexible printed circuits which are connected to the control circuit board. The control circuit board is sandwiched between the metal frame and the shield member, and the metal frame is arranged between the control circuit board and the liquid crystal display panel.

Abstract:
A surface light source device includes a light source body having an internal space into which a discharge gas is injected, and an electrode for applying a voltage to the discharge gas. Partition walls are arranged in the internal space to divide the internal space into a plurality of discharge spaces. To reduce areas of the partition walls, a groove is formed at a side face of each partition wall. Thus, each partition wall has a reduced area so that the partition walls may not act as dark fields of the surface light source device.
Abstract:
A backlight assembly includes a receiving container having a bottom and a side member to provide a receiving space, a flat-type fluorescent lamp received into the receiving container to emit a light, and a supporting member having a buffer disposed between the receiving container and the flat-type fluorescent lamp to buff an impact applied to the flat-type fluorescent lamp while supporting the flat-type fluorescent lamp. The buffer has protrusions protruding from a face of the supporting member. Thus, the backlight assembly may enhance impact resistance of the backlight assembly and prevent damage of the flat-type fluorescent lamp.

Abstract:
The present invention discloses a flat fluorescent lamp which can improve discharge efficiency and luminance by increasing a current density per discharge channel by forming a plurality of independent meandering discharge channels on a rear substrate, lowering a discharge initiation voltage by auxiliary electrodes and internal and external discharge electrodes, and minimizing non-luminescent regions by the external electrodes. A sidewall is installed to form an airtight space between front and rear substrates, cross walls for forming a plurality of independent meandering discharge channels are installed on the rear substrate, and discharge electrodes are disposed at both sides of the starting and terminating ends of the plurality of meandering discharge channels, for discharging the meandering discharge channels in parallel.

A dielectric barrier discharge lamp comprises a discharge vessel that has a principal axis, the discharge vessel encloses a discharge volume filled with a discharge gas. The discharge vessel further comprises end portions intersected by the principal axis. There are at least one electrode of a first type and at least one electrode of a second type in the lamp. The electrodes of one type are energized to act as a cathode and the electrodes of other type are energized to act as an anode. The electrodes are substantially straight, elongated and have a longitudinal axis substantially parallel to the principal axis of the discharge vessel. These electrodes are positioned within the discharge volume. The electrodes of at least one type are isolated from the discharge volume by a dielectric layer. A dielectric barrier discharge lamp is also disclosed, in which the electrodes are arranged within the discharge volume in groups, and each of the groups comprises one electrode of the first type and at least one electrode of the second type.
