Display fabrication using modular active devices
View Patent ↗A method for fabricating a display device patterns a conductive layer on a display substrate and forms pixel electrodes on the display substrate. A plate is employed for carrying separately fabricated active devices to the display substrate. The separately fabricated devices are connected to the conductive layers and the pixel electrode.
1. A display device, comprising:
gate lines and data lines patterned from a single layer of conductive material;
pixel electrodes formed in operative relationship with the gate lines and data lines; and
a plurality of chiplets connected to the gate lines, the data lines and the pixel electrodes such that the chiplets activate the pixel electrodes in accordance with the gate lines and the data lines.
2. The display device as recited in claim 1 , wherein the display device includes one of an active matrix liquid crystal display and an organic light emitting diode display.
3. The display device as recited in claim 1 , wherein the plurality of chiplets are connected to the gate lines, the data lines and the pixel electrodes by conductive attachments.
4. The display device as recited in claim 3 , wherein the conductive attachments include at least one of solder bumps, conductive adhesive bumps and thermocompression bond pads.
5. The display device as recited in claim 1 , wherein the plurality of chiplets provide a cross-over connection between data line segments.
6. The display device as recited in claim 1 , wherein the chiplets each include a transistor which is connected to at least a data line and a gate line.
7. The display device as recited in claim 1 , wherein the chiplets each include a storage capacitor.
8. The display device as recited in claim 1 , wherein the chiplets include a size related to a fraction of sub-pixel size for sub-pixels of the display device.
