Abstract: In a Q-tuple anode matrix vacuum fluorescent display (VFD), a plurality of selected pixels are turned on one by one to sequentially emit lights in accordance with a display signal. Each selected pixel is selected from Q anode segments to be turned on to emit lights by turning on a first and a second grid electrode positioned adjacent to each other. Each selected pixel is formed of Q/2 anode segments in total including R anode segments sequentially disposed from a position closest to the first grid electrode and facing the second grid electrode and (Q/2?R) anode segments sequentially disposed from a position closest to the second grid electrode and facing the first grid electrode, R being an integer ranging from 1 to (Q/2?1).

Abstract: An active matrix display device includes a CPU; a glass substrate; and a display panel unit formed on the glass substrate, the display panel unit including a control unit and a display section together. The display panel unit is provided with a data input terminal, a clock terminal and a data latch terminal, which are connected to the CPU, a test terminal to which a test signal from the CPU is inputted, and a data output terminal for outputting data written to the display section upon input of the test signal. The display panel unit may be further provided with a write enable terminal for receiving a write control signal; and a blank terminal for adjusting brightness of the display section.

Abstract: A high-intensity, uniformed luminescence, high-density active matrix fluorescent display tube having plural pixels, plural scanning lines and plural signal lines is disclosed. The display element includes a logic circuit, a holding unit, an AND circuit, a pre-driver circuit, and a pixel driver. The logic circuit is composed of a row address selection circuit for each pixel, input data and a logic control circuit. The holding unit drives an anode electrode disposed for each pixel. The AND circuit performs logical product on a signal held in the holding unit and a blanking reverse signal from an input data signal line. The pre-driver circuit drives the output transistor in the previous stage. The pixel driver is conformed of the driver output circuit connected to the pre-driver circuit. The pre-driver circuit is formed of an enhancement-mode P-channel field-effect transistor and a depletion-mode P-channel field-effect transistor.
