We designed novel reflective metal groove plates as the anode, and there are different groove structures on them. By mixing the white color phosphor and cellulose acetate butyrate (BCA) solution and spraying it uniformly on the groove surface, then the metal groove plate was fixed on the indium tin oxide (ITO) glass substrate. In cathode, thick film screen printing method was used to print long narrow strips of CNT paste on the surface of cathode electrode that had been fabricated by the same method. And, the anode and cathode plates have been set up in the vacuum chamber for the measurements.
The reflective metal groove plate had five advantages listed in the following：
1.It can sustain high field emission current.
2.It can quickly deliver the space charges from the phosphor surface to the outside chamber by the anode circuit.
3.It can rapidly transmit the thermal energy of the anode created by the electron bombardment and reduce the anode temperature.
4.It has groove structure and reflective surface which can increase the illumination area and light uniformity outside the panel.
5.No spacers in packaging the backlight panel, it can avoid the fracture of the glass within vacuum pumping.
We successfully fabricated a 7 inches backlight panel with the light coming out from the cathode plate. With one diffuser and two brightness enhanced films (BEFs), the results showed that the illumination of 11530nits at high uniformity with the applied voltage of 3.75KV was demonstrated and I-V measurements were also illustrated.
