  • Publication number: 20090033589
    Abstract: An increase in the circuit size of a drive circuit that accompanies multi-gradation is reduced. Herein, VI0 to VIM are modulation circuit reference voltages in which a prescribed range, i.e., from a non-emission voltage VEOFF to a maximum emission voltage VEON, is divided in M equal parts. Higher-order dividing resistor (40) equally divides the parts of the modulation circuit reference voltages VI0 to VIM (where VI0>VI1 . . . >VIM?1>VIM) and generates 2J+1 higher-order gradation voltages v0 to v8M (where 8M is equal to 2J) A higher-order decoder unit (41) selects two adjacent voltages from the higher-order gradation voltages in accordance with the data of the higher-order J bits held in the data latch. Complimentary MOSFET selection switches (47-1) and (47-2) open and close in accordance with the lowest-order bit data inputted to the higher-order decoder unit (41).

  • Publication number: 20070103087
    Abstract: To detect a dark current when an abnormal discharge occurs between an anode and respective electrodes, on an inner surface of a front substrate, a dark current detection electrode is formed in a state that the dark current detection electrode is positioned adjacent to the outside of a screen display region on which an anode is formed and on a plane substantially equal to a plane on which the anode is formed. Then, between an electrode terminal of the dark current detection electrode and a ground, an ammeter which detects the flow of a dark current and a DC power source having a preset voltage value which is more or less lower than a high voltage supplied to the anode are connected in series.

  • Patent number: 7190107
    Abstract: A field emission type display device has a structure in which each pixel is constituted of a combination of a plurality of small apertures and a plurality of small electron sources. Due to such a constitution, it is possible to reduce undesired impact of electrons on control electrodes and the enhancement of the heat resistance of the carbon nanotubes of electron sources, whereby it is possible to obtain a display device of high quality and long lifetime, while exhibiting a high-performance electron emission characteristic. Boron (B) is adhered to carbon nanotubes, which constitute electron sources, through the small apertures of the control electrodes; and, hence, the alignment of the small apertures and the small electron sources is ensured and the area of the electron source is set to be equal to or less than the area of the aperture.

  • Publication number: 20070052655
    Abstract: In a display device which includes a scanning circuit, an ON resistance of a non-selection switch of the scanning circuit is set larger than an ON resistance of a selection switch. By setting the ON resistance of the non-selection switch of the scanning circuit larger than the ON resistance of the selection switch, an element size of the non selection switch can be made small and hence, a chip size of a scanning driver which is formed of a semiconductor integrated circuit constituting a scanning circuit can be made small without adversely influencing the display characteristics of the display device.
