Patent number: 8519627Abstract: Provided is a field emission device having a simple structure and capable of pulse driving and local dimming. The field emission device turns a current flowing from each cathode electrode block on or off in response to a switching control signal having a very low voltage ranging from 0 to 5 V while a constant voltage is applied to an anode electrode and a gate electrode to control a field emission current. Compared with a conventional field emission device, the field emission device having a simple structure is capable of pulse driving and local dimming without using a separate pulse driving high voltage power source.Type: GrantFiled: July 14, 2009Date of Patent: August 27, 2013Assignee: Electronics and Telecommunications Research InstituteInventors: Jin Woo Jeong, Yoon Ho Song, Dong Il Kim, Jun Tae Kang, Ji Seon Kim

Patent number: 8264151Abstract: 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.Type: GrantFiled: August 31, 2009Date of Patent: September 11, 2012Assignee: Electronics and Telecommunications Research InstituteInventors: Jin Woo Jeong, Yoon Ho Song, Dong Il Kim, Jun Tae Kang, Ji Seon Kim
