Patent ID: 7491559

Claim:
A method for producing a display panel on a substrate having a first area and a second area, the display panel having a display area in the first area and an electronic circuit area in the second area electrically connected to the display area, the display area comprising display components, the electronic circuit area comprising electronic components, said method comprising the steps of: disposing an amorphous silicon layer on the substrate; converting the amorphous silicon layer in both the first and second areas into substantially a poly-silicon layer by a solid-phase cystallization process; further annealing the poly-silicon layer in the second area by a laser beam for providing a further annealed poly-silicon layer; fabricating the display components in the poly-silicon layer in the first area; fabricating the electronic components in the further annealed poly-silicon layer in the second area; and providing electrical connections between the display area and the electronic circuit area.
