  • Patent number: 6097359
    Abstract: A cell driving device of a field emission display according to a passive matrix addressing method having a field emission pixel cell with a cathode (10) and a gate electrode (12) for emitting electrons from the cathode. The cell driving device includes at least two current sources (18, 20) disposed to provide a current signal to the cathode; and a controlling part (22) for selectively driving at least two current sources (18, 20) according to the size of a video signal.

  • Patent number: 6088011
    Abstract: A color plasma display panel including a pixel matrix array (R, G, B) in which discharge cells of the red (R), green (G) and blue (B) are grouped to constitute a pixel, wherein the pixel includes a blue discharge cell (B) having a height smaller than the entire height of the pixel and width equal to entire width of the pixel (R, G, B), and red and green discharge cells laterally aligned with each other, each of the red and green discharge cells having a height corresponding to a difference between the entire height of the pixel and the height of the blue discharge cell (B) and a width less than 1/2 the entire width of the pixel. The pixel further includes an assistant cell (M) disposed between the red and green discharge cells and priming holes (H) respectively provided at partition walls each disposed between each of the red (R) and green (G) discharge cells and the assistant cell (M).

  • Patent number: 5953003
    Abstract: A flat display driving includes a gate driving circuit for sequentially and selectively applying a high voltage to a plurality of gate lines to drives them; a data driving circuit which includes a shift register for sequentially inputting one line of pixel data, a current source array which inputs on line of pixel data from the shift register, generates one line of current signals corresponding to each logic value of the pixel data and applies one line of current signals to the data lines and a latch type transmission array connected between the shift register and the current source array, for adjusting the supply time of one line of pixel data to be applied to the current source array, thereby driving the pixels on one horizontal line of the field emission display by the current signals for a predetermined time period; and a control circuit which processes a video signal into a series type of pixel data, supplies it to the data driving circuit and generates control signals required for the data driving circu
