Active matrix display
View Patent ↗An active matrix display includes a substrate, a video signal line on the substrate, first and second power lines on the substrate, a self-emitting element having two display electrodes facing each other and connected to one of the first and second power lines, a drive transistor connected between the first power line and one of the display electrodes, a storage capacitor having a first electrode connected to a gate electrode of the drive transistor and a second electrode facing the first electrode with interposing an insulating layer, the storage capacitor and the gate electrode of the drive transistor being arranged under the display electrode, and a shield electrode arranged between the display electrode connected to the drive transistor and at least one of the first electrode of the storage capacitor and the gate electrode with interposing an insulating layer, and set at a constant potential.
1. An active matrix display comprising:
a substrate;
a video signal line formed on the substrate and extending in a first direction;
a control line provided on the substrate and extending in a second direction perpendicular to the first direction;
an self-emitting element including two display electrodes facing each other;
a drive transistor connected to one of the display electrodes of the self-emitting element and having a gate electrode arranged under the display electrode connected to the drive transistor;
a storage capacitor having a first electrode connected to the gate electrode of the drive transistor and arranged under the display electrodes, and a second electrode facing the first electrode interposing an insulating layer;
an output switch connected between the drive transistor and the self-emitting element, and configured to control light emission of the self-emitting element, and wherein the control line includes a light emission control line connected to the output switch and configured to turn on or off the output switch; and
a shield electrode arranged between the display electrode connected to the drive transistor and the capacitor with interposing an insulating layer, and connected to the light emission control line.
2. The active matrix display according to claim 1 , wherein the self-emitting element includes an organic light-emitting layer interposed between the two display electrodes.
3. The active matrix display according to claim 2 , wherein the self-emitting element is configured to emit light toward a side opposite to a side of the substrate.
4. The active matrix display according to claim 3 , wherein one of the two display electrodes of the self-emitting element is provided on the side of the substrate and faces the shield electrode interposing an insulating layer, and the other display electrode is provided on a side opposite to the substrate with respect to said one of the display electrodes and has optical transparency.
