US Patent 7145527 Field emission display device and driving method thereof

A field emission display device is provided which includes data lines formed in a panel, scan lines formed in the direction crossing the data lines in the panel, a first connector installed at an end of the data lines and electrically connected with the data lines, a second connector installed at an end of the scan lines and electrically connected with the scan lines and a printed circuit board which is installed on the rear surface of the panel. The flat emission display device can display an image of a uniform brightness regardless of the position of the screen. Also, the flat emission display device can maintain the brightness of the whole screen uniformly by differently supplying the driving voltage and pulse width of the driving voltage which are supplied to the data driving unit according to the position of the data line, and compensating voltage descending caused by differences in the resistance according to the is position of the scan line by converting the input data value.
