Abstract
The present invention relates to design and processes for the manufacture of backplane for segment displays.
Claims19
A direct drive display which comprises segment electrodes wherein said segment electrodes are separated by a non-conductive material hardened from a thermal or radiation curable material.
A process for plugging gaps between segment electrodes in a direct drive display which process comprises filling the gaps with a thermal or radiation curable material and hardening said thermal or radiation curable material.
A process for the manufacture of a backplane which process comprises:
- a) forming conductive lines on a non-conductive substrate layer;
- b) covering the conductive lines with a photoimageable material;
- c) forming conductive areas connected to the conductive lines and embedded in the photoimageable material;
- d) plating a conductive material over the photoimageable material to form segment electrodes;
- and
- e) optionally filling gaps between said segment electrodes with a thermal or radiation curable material followed by hardening said thermal or radiation curable material.
A process for the manufacture of a backplane which process comprises:
- a) forming via holes on a non-conductive substrate layer laminated or coated with a conductive material on both sides;
- b) filling the via holes with a conductive paste;
- c) if necessary, removing protrusions formed from the conductive paste at the openings of the via holes;
- d) forming segment electrodes on the conductive material laminated or coated on one side of the non-conductive substrate layer and conductive lines on the conductive material laminated or coated on the other side of the non-conductive substrate layer;
- and
- e) optionally filling gaps between said segment electrodes with a thermal or radiation curable material followed by hardening said thermal or radiation curable material.
