A container receives lamps each having a lamp tube and a conductive member. The container includes a container body exposing the lamp tube and covering the conductive member, and a clip type power-supply unit holding the conductive member in a clip-coupling manner so that the container securely receives the lamps. The clip type power-supply unit supplies power to the conductive member. The clip type power-supply unit has a conductive base body coupled to the container body, a clip body protruded perpendicularly from the conductive base body, and a clip section protruded from the clip body to grip the conductive member. The container also has a shock absorbing member disposed between the container body and the clip type power-supply unit.

In a backlight assembly and a liquid crystal display apparatus, a plurality of lamps disposed in a receiving space of the backlight assembly is spaced apart from each other by various intervals between the lamps depending upon positions at which the lamps are disposed. Each of the lamps may also have an external electrode having a different area from each other or due to the positions at which the lamps are disposed. Furthermore, each of the lamps may have a different amount of discharge gas injected thereinto due to the positions at which the lamps are disposed. Accordingly, the liquid crystal display apparatus may provide a uniform brightness, and prevent deterioration of display quality thereof.

Disclosed are a displaying substrate and a liquid crystal display device having the same. A pad portion formed on the displaying substrate has a plurality of via holes for exposing a pad metal layer. A width of the via hole is smaller than a diameter of a conductive particle. Where the width of the via hole is larger than the diameter of the conductive particle, a depth of the via hole is smaller than the diameter of the conductive particle. Thus, a driving failure which may occur in the pad portion is prevented while maintaining a deformation ratio of the conductive particle at about 20˜60%, thereby enhancing a connecting force between the pad portion and a circuit substrate.

A planar light source device includes a lower substrate, a cathode electrode a carbon nanotube, an upper substrate, a fluorescent layer, and an anode electrode. The cathode electrode is on the lower substrate. The carbon nanotube is electrically connected to the cathode electrode. The upper substrate faces the lower substrate. The fluorescent layer and the anode electrode are formed on the upper substrate. Therefore, the planar light source device generates light without using mercury.

A lamp assembly includes a lamp and a lamp driving device. The lamp includes a body and first and second electrodes. The body converts invisible ray generated by a discharge into visible ray, and the electrodes are disposed on the body. The lamp driving device provides the first and second electrodes with first and second driving voltages, respectively, to generate the discharge. The first driving voltage is less than a first critical voltage at which a corona discharge occurs at the first and second electrodes. When the first electrode is electrically connected to a ground, the first critical voltage may be about 1,200 volts. When the second driving voltage has an inverted phase with respect to the first driving voltage, the first critical voltage is about 2,400 volts. An ozone gas may not be generated at the first and second electrodes to prevent the damage of the electrodes.
摘要:
In a lamp and method for fabricating the same, an outer surface of the lamp tube is dipped into a conductive transparent solution for forming an electrode by a predetermined depth, and then the lamp tube is pulled out from the solution. Accordingly, an electrode having different profiles is formed on the outer surface of the tube body. Also, the outer surface of the lamp tube is dipped into the solution by an acute angle, and is pulled out from the solution. Therefore, a problem of a nonuniform brightness between lamps is not generated, and light utilization efficiency is much enhanced even when using a plurality of lamp in parallel connected to a power supply.

A lamp assembly for a liquid crystal display device includes a lamp tube for generating light, and electrodes each having a suitable shape for receiving end portions of the lamp tube. The lamp tube and the electrodes are combined to generate the light by applying electric power to the electrodes. The lamp assembly may include multiple lamp tubes having different brightness from each other, in which the brightness difference between the lamp tubes is compensated by uniformly diffusing the light generated from the lamp tubes.
