Video display

Abstract

The present disclosure provides a video display comprising a substrate having electrodes. A mask layer covers a portion of the electrodes, stacked gates is over the mask layer. Emitters are formed on a portion of the electrodes to emit electrons, wherein the stacked gates are used for extracting electron beam from the emitters, wherein the emitters is formed with carbon nanotube emitter to improve video images and local brightening for display; and a panel disposed above the stacked gates; a fluorescent film attached to a surface of said panel and the fluorescent film being hit by electron emitted from the emitter to emit color for display.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The application is a continuation application of Ser. No. 11 / 724,262, filed on Mar. 15, 2007, now pending, which is a continuation in part application of U.S. patent application Ser. No. 11 / 011,465, filed on Dec. 13, 2004, now abandoned, which are herein incorporated by reference in its integrity.TECHNICAL FIELD[0002]The present invention relates generally to a portable device, and more particularly to a computing device with field emitter.BACKGROUND OF THE RELATED ART[0003]Cellular communications systems typically include multiple base stations for communicating with mobile stations in various geographical transmission areas. Each base station provides an interface between the mobile station and a telecommunications network. Mobile telephone systems are in use or being developed in which the geographic coverage area of the system is divided into smaller separate cells, it communicates with the network via a fixed station located in the c...

AI Technical Summary

Benefits of technology

[0008]A device comprises a control unit; a memory coupled to the control unit to store data; a substantially transparent panel to minimizes EM shielding effect, wherein the substantially transparent panel includes a first substrate having a transparent electrode coupled to the control unit, a stacked gate formed over the first substrate and emitters formed adjacent to the stacked gate, a second substrate having fluorescent substances spaced apart from the first substrate, wherein the fluorescent substances emits green, blue or red light while electrons emitted by the emitter contact to the fluorescent substances. The portable device further comprises an antenna located corresponding to the substantially transparent panel to minimize the EM shielding effect, thereby improving signal receiving / transmitting performance. Alternatively, the portable device comprises at least one transparent antenna attached on the substantially transparent panel to minimize the EM shielding effect.

Problems solved by technology

Furthermore, the conventional LCD display has a lot of drawbacks, for example, the LCD display needs back light module which increases the thickness of the panel and it is not transparent.

Moreover, the device requires large arrays of thin film transistors, the manufacture is complicated and the resolution is not high enough.

The mouse is inconvenient to a user, especially, to a portable device.

But the goal of size reduction is frustrated by the present of the elements mentioned above.
