摘要： There is a provided a surface light source device comprising: a light source body having an inner space therein in which a discharge gas is contained; a plurality of electrodes formed on the light source body in such a manner as to electrically divide the inner space into at least three blocks and applying discharge voltages to the blocks; and a driving unit sequentially applying the discharge voltages to the blocks through the electrodes in synchronization with a video signal of an external display device. The light source body may have a plurality of discharge spaces or a single discharge space therein. In accordance with the present invention, the surface light source device sequentially applies the discharge voltages to the blocks, and thereby can reduce an after-image occurring in a liquid crystal display device. Further, the surface light source device is driven with a duty ratio varied depending on brightness of the video signal, and thereby integrated power consumption can be reduced and a contrast ratio can be improved.

摘要： A flat fluorescent lamp which can be used with an LCD display includes a plurality of discharge channels. Pairs of electrodes are formed on both ends of the discharge channels. Each of the plurality of channels has an emitting section at the middle, and electrode sections on both ends thereof. A width of the electrode sections is the same as that of the emitting section. However, a height of the electrode sections is greater than a height of the emitting section, resulting in the electrode section having a cross-sectional area that is larger than that of the emitting section.
