Abstract:
A field emission anode plate (1), a filed emission light source and a manufacturing method for the light source are provided. The field emission anode plate comprises a transparent ceramic base (10) and an anode conductive layer (11) provided on the surface of the transparent ceramic base which can be excited to produce light by cathode rays. The filed emission light source comprises the field emission anode plate, a field emission cathode plate (2) and a supporter (3). The field emission cathode plate comprises a substrate (20) and a cathode conductive layer (21) provided on the surface of the substrate. The anode conductive layer and the cathode conductive layer are arranged opposite to each other, and two ends of the supporter are hermetically connected to the field emission anode plate and the field emission cathode plate respectively, thus the field emission anode plate, the field emission cathode plate and the supporter constitute a vacuum chamber. As the transparency and electron-impact resistance are improved and the corrosion and wear resistance properties are increased, the field emission anode plate is low-cost with luminance uniformity, and the filed emission light source also exhibits high luminance intensity, luminance uniformity and a long service life.
