| 20100156297 | COLOR VARIABLE FIELD EMISSION DEVICE - A field emission device having a simple structure and capable of readily changing emission colors of light by adjusting emission intensity of red, green and blue light is provided. In the field emission device, current that flows into each cathode electrode block is adjusted according to a very low control pulse signal of 0 to 5 V with a predetermined voltage applied to an anode electrode and a gate electrode over time, so that emission intensities of red, green and blue are individually adjusted. Therefore, the current that flows into each cathode electrode block is adjusted in a simple manner using a control pulse signal of a low level without a separate pulse driving high-voltage power supply, so that emission intensities of red, green and blue can be arbitrarily adjusted and emission colors of the field emission device can be readily changed. | 06-24-2010 |
| 20110148310 | FIELD EMISSION LAMP - Provided is a field emission lamp (FEL), which includes a plurality of cathode electrodes formed above a first substrate, an anode electrode formed under a second substrate to face the cathode electrode, a fluorescent layer composed of red, green and blue (RGB) patterns formed alternately on the anode electrode in an oblique direction, and a plurality of emitters formed on the cathode electrodes to correspond to the RGB patterns. According to the present invention, as an FEL having a fast response time is used as a backlight unit, a color breaking phenomenon can be prevented in a color sequential driving method. | 06-23-2011 |
