| 20080252196 | Active-Matrix Field Emission Display - Provided is a field emission display (FED) in which field emission devices are applied to a flat panel display. The FED includes: a cathode plate including a substrate, first and second thin film transistors (TFTs) that are serially connected on the substrate, a field emitter disposed on a drain electrode of the second TFT, a gate insulating layer having a gate hole surrounding the field emitter, and field emission gate electrodes disposed on the gate insulating layer; and an anode plate including a substrate, and red, green, and blue phosphors disposed on the substrate, wherein the cathode plate and the anode plate are vacuum-packaged parallel and opposite to each other. According to the present invention, uniformity of the FED panel can be significantly improved, and an inherent source-drain leakage current of the TFT can be significantly reduced, so that a contrast ratio of the FED can be significantly enhanced. | 10-16-2008 |
| 20080284314 | Active-Matrix Field Emission Pixel and Active-Matrix Field Emission Display - Provided is a field emission display (FED) capable of driving on the basis of current and preventing leakage current caused by thin film transistors (TFTs). The FED includes: a plurality of unit pixels including an emission element in which cathode luminescence of a phosphor occurs and a TFT for driving the emission element; a current source for applying a scan signal to each unit pixel; and a voltage source for applying a data signal to each unit pixel. Here, the on-current of the current source is high enough to take care of the load resistance and capacitance of a scan row within a given writing time, and the off-current of the current source is so low that the electron emission of each pixel can be ignored. In addition, the pulse amplitude or pulse width of the data signal applied from the voltage source is changed, and thereby the gray scale of the display is represented. | 11-20-2008 |
