Method of manufacture of the cathode of a microtip fluorescent screen and the product obtained by this process .

摘要

The present invention relates to a method of manufacture of the cathode of a microtip fluorescent screen, as well as the product obtained by this process. & br / the method consists in etching sets the three upper layers of the cathode, the grate (6), the gate insulator (5) and the resistive layer (3), in a single perforated pattern defining both the grid lines and the access resistance to the microtips (4) by the resistive layer, the column conductors (2) consisting of a metal grid. & br / & it relates to the industrial sector display screens flat matrix addressing lines - columns, and more particularly of the display screens using the technology of the microtips.
