Abstract
A pixel device including a first floor including a first LED, a first lower pad, and a first upper pad electrically connected to the first LED; a second floor disposed over the first floor, and including a second LED, a second lower pad, and a second upper pad electrically connected to the second LED; and a third floor disposed over the second floor, and including a third LED, a third lower pad, and a third upper pad electrically connected to the third LED.
Claims18
A pixel device, comprising:
- a first floor including a first LED, a first lower pad, and a first upper pad electrically connected to the first LED;
- a second floor disposed over the first floor, and including a second LED, a second lower pad, and a second upper pad electrically connected to the second LED, the second floor further including a second insulation layer covering the second LED and a second planarization layer covering the second insulation layer;
- and
- a third floor disposed over the second floor, and including a third LED, a third lower pad, and a third upper pad electrically connected to the third LED,
- wherein the third floor further includes a third insulation layer covering the third LED and a third planarization layer covering the third insulation layer, the third LED, and the third lower pad;
- the third lower pad is disposed between the third insulation layer and the second planarization layer;
- and
- the third upper pad is disposed above the third planarization layer, and the third lower pad extends from a bottom of the third LED toward an outside of the third LED.
