Abstract (en)
[origin: GB2440783A] A field emission backplate 5a used in a field emission device such as a display device, and an associated method of manufacture. A field emission backplate 5a comprises a substrate 10a, a cathode metal layer 11a upon which is deposited an amorphous semiconductor layer 15a comprising hydrogenated amorphous silicon. The backplate 5a is exposed to laser irradiation so as to form a plurality of conductive or conducting particulates or particles 20a within the amorphous silicon layer 15a. The surface 25a may be substantially flat or planar, or may comprise a plurality of tips.
