| 20110199359 | DISPLAY PANEL - An EL light-emitting element is driven digitally to reduce power consumption using a pixel having three transistors and two capacitors. A reset transistor for diode connection writes the threshold voltage of the drive transistor onto a coupling capacitor. The data voltage plus threshold voltage is then written onto the gate of the drive transistor. This reduces the amplitude of the data voltage required, further reducing power consumption. | 08-18-2011 |

| 20100231484 | LED DEVICE HAVING IMPROVED LIGHT OUTPUT - A light-emitting microcavity diode device includes a reflective electrode and a semi-transparent electrode, formed over a substrate, with an unpatterned light-emitting layer formed between the reflective electrode and the semi-transparent electrode. The reflective electrode, semi-transparent electrode, and unpatterned light-emitting layer form an optical cavity. Either the reflective or semi-transparent electrode is patterned to form independently-controllable, light-emitting sub-pixels. At least one, and fewer than all, of the sub-pixels emit light through a color filter. A first sub-pixel emits light having a first primary color and a second sub-pixel emits a complementary colored light. The light emitted from the first and second sub-pixels changes at one or more different angles. The color of the combined light of the first and second sub-pixels changes less at the one or more different angles than the light from at least one of the first or second sub-pixels. A third sub-pixel emits light through a color filter of a second primary color, different from the first primary color. | 09-16-2010 |
