Patent ID: 7585703

Claim:
A method for selectively transferring onto a planar display substrate pixel control devices each controlling a plurality of pixels, comprising the steps of: fixing a device substrate having pixel control devices for controlling the plurality of pixels onto a support substrate, each of said pixel control devices having an integrated circuit on a surface thereof; cutting the device substrate into individual pixel control devices with the integrated circuit; fixing the pixel control devices on the support substrate onto a pickup substrate; holding the pixel control devices on the pickup substrate by a pickup device and transferring the pixel control devices on the pickup device onto the planar display substrate; and forming the pixels on a surface of the planar display substrate; wherein a plurality of pixel control devices is formed on the device substrate at a first direction array pitch px/m that is obtained by dividing an array pitch px in a first direction on the planar display substrate by a natural number m and at a second direction array pitch py/n obtained by dividing an array pitch py in a second direction on the planar display substrate that is orthogonal to the first direction by a natural number n; wherein the pixel control devices only corresponding to the array pitches px and py of the planar display substrate are selected from the pixel control devices fixed onto the pickup substrate and then transferred onto the planar display substrate; and wherein each of the pixel control devices controls 3 colors×4 pixels arrayed in 2 columns and 6 rows and is transferred to a center of the pixels arrayed in 2 columns and 6 rows.
