Reversal coplanar type ballast structural panel display device and its production technique

Abstract

The invention relates to a plate display in reversed coplanar rectify structure and relative production, wherein it comprises an anode glass panel, a cathode glass panel, and a sealing vacuum chamber surrounded by four glass frames; the anode glass panel is arranged with anode conductive layer and a fluorescent powder layer is above the conductive layer; a support wall structure and a gattering additional element are between the anode glass panel and the cathode glass panel; a control grid, a carbon nanometer tube cathode and reversed coplanar rectify structure are arranged on the cathode glass panel. The invention can effectively control the current of cathode, to control its field activated emission ability, to increase or reduce the number of emitted electrons to adjust the pixel brightness to improve the light uniformity of display image, with lower cost and simple structure.

Problems solved by technology

With the increase of the display area in the display device, the number of corresponding carbon nanotube cathodes increases geometrically. Then, in such a large number of carbon nanotube cathodes, it is difficult to ensure that all carbon Nanotube cathodes all have the same field emission capability, and it is difficult to ensure that the phosphor layer corresponding to the carbon nanotube cathode emits the same intensity of visible light; because the luminance of different phosphor pixels may be different, it also causes display devices poor display image quality
