Embodiment Construction

[0025] Referring to FIG. 1 , the display unit includes two glass substrates: a front glass substrate 100 and a rear glass substrate 170 . The space between the front glass substrate 100 and the rear glass substrate 170 is a vacuum space 180, and the vacuum degree requires 10 -5 ~10 -1 Torr. The front glass substrate 100 and the rear glass substrate 170 are supported by the supporting pillars 130 so that the distance between the two substrates is consistent, and the height of the supporting pillars is between 0.1-5mm. Scanning electrodes 160 are formed on the rear glass substrate, ferroelectric thin films 150 are formed on the scanning electrodes, and grid-shaped address electrodes 140 are formed on the ferroelectric thin films 150 . An ITO anode 110 is fabricated on the side of the front glass substrate 100 opposite to the rear glass substrate, and phosphor powder 120 is coated on the ITO anode 110 . Ferroelectric thin film material can adopt ferroelectric materials such as...

Abstract

This invention discloses a panel display device adopting iron conductive film as cathode, which comprises two base boards made of glass and isolated by a distance of 0.1-5mm, wherein, its middle is vacuum-pumped and supported by bracing column; the said rear glass base plate is located with a set of parallel scanning bar electrodes with iron conductive film with a set of parallel bar grid address finding electrodes vertical to the scanning electrode; the said former glass base plate has a ITO anode coating fluorescent powder corresponding to the rear one; there is one display unit in the crossing position between each scanning electrode and address finding electrode; three display units adjacent are coated separately with red, green and blue fluorescent powder to form a picture element.

Description

technical field [0001] The invention relates to a ferroelectric flat panel display device, in particular to a structure of a flat panel display device using a ferroelectric thin film as a cathode. Background technique [0002] The electron emission phenomenon of ferroelectric thin film cathodes has been extensively studied in recent years. Different from the cold cathode field electron emission, the ferroelectric thin film cathode repels the compensation electrons on the surface through the polarization reversal inside the film, and can emit electrons without the extraction voltage. It is a new type of low voltage electron emitting material. In order to reduce costs and facilitate mass production, it is expected that flat panel display devices can operate at the voltage level of integrated circuit devices, ie, from a few volts to 100 volts. In 1995, O.Auciello and others in the United States found experimentally (Applied Physics Letters, volume 66, period 17, 1995, pages 2...
