Abstract: |
The method includes following steps: a) provides a insulation base board with two flat surfaces; b) a metal film is formed on each of two flat surfaces; c) uses photo etching method to form bar grid on the metal film; d) on the place of metal film at another side of insulation base board where bar grid opposites to, a part of metal film and insulation base board is etched and removed to form through-hole and acquire electrode module with bar grid focusing electrode; e) the electrode module, field emission cathode and screen are aligned and packaged to form field emission display. |
