Flat board display of splayed inclined bar control structure and its making process

Abstract

This invention relates to a flat display of slant grid-control structure and its manufacturing method including a closed vacuum cavity composed of an anode glass panel, a cathode glass panel and glass frame around it, in which, an anode conductive layer is set on the anode glass panel and a fluorescent powder layer is prepared on the anode conductive layer, a supporting wall structure and attached elements of a getter is set between the anode glass panel and the cathode glass panel, a grid lead layer, carbon nanometer tubes and a slant grid-control structure are set on the cathode glass panel to control efficiency of the grid structure and increase the electronic emission efficiency and quantity to increase image quality of the device.

Description

technical field

[0001] The invention belongs to the fields of flat panel display technology, microelectronic science and technology, vacuum science and technology, and nano science and technology, and relates to device fabrication of flat panel field emission displays, in particular to carbon nanotube cathodes. The device manufacturing aspect of the flat field emission display, especially relates to a flat panel display with a figure-eight oblique grid control structure and its manufacturing process. Background technique

[0002] In recent years, flat panel display technology has been greatly developed. Driven by high-definition televisions, computer monitors, automotive terminal display equipment, and military helmet visors, display technology is moving towards high-resolution, low-efficiency Voltage, planarization, and large-scale development. Field emission display is a light-emitting device made by applying vacuum microelectronics technology to display equipment. It has...
