Embodiment Construction

[0008] figure 1 An enlarged cross-sectional view of a field emission device display 10 utilizing matrix addressing is schematically shown. The display 10 includes a substrate 11 on which other parts of the display 10 are formed. Generally, the substrate 11 is an insulating or semi-insulating material, such as a silicon material with a dielectric layer or glass. In a preferred embodiment, substrate 11 is glass. Typically, a cathode conductor or column 12 is formed on the surface of substrate 11 by which emitter tips or electrodes 13 and 17 are connected to a column of display 10 . The material used for column 12 may be a metal or a low resistance layer such as doped polysilicon. The first extraction gate or row 27 and the second extraction gate or row 19 are electrically isolated from the substrate 11 and the columns 12 by means of the dielectric layer 16 . Electrons are emitted by the emitters 13 and 17, and the emitted electrons are collected by the anode 18 disposed at a...

Abstract

A display (10) applys a show driving circuit, which can employ the reduction of the working frequency used in row (12) information in the image to minimize the power consumption, the reduction of working frequency is relied on a current level showing time which also has data to display, thus making the the row timing signal (32) postion near the terminal of the level showing time(38, 39, 48, 49).

Description

Technical field: [0001] The present invention relates to a display device, in particular to a novel control method for the display device. Background technique: [0002] Various display devices such as liquid crystal displays, light emitting diode displays and electroluminescent device displays have long been controlled using matrix addressing. Matrix addressed displays typically have many rows and many columns forming an X-Y matrix. Activation of a specific row and a specific column results in a visible pixel appearing at the intersection or intersection of the row and column. Usually each row is enabled sequentially, and data is added to each column simultaneously, so when each row is enabled, all columns are enabled simultaneously. [0003] One problem with this kind of matrix addressing is power consumption. In electroluminescent device displays, the majority of the power consumed within the display for each row is the concomitant capacitive power dissipation when the...
