Light emitting display having decreased parasitic capacitance
View Patent ↗A light emitting display including a plurality of scan lines; a plurality of data lines crossing the scan lines; a plurality of pixels defined by the scan lines and the data lines; and a light emitting device formed on a pixel and comprising a first electrode and a second electrode. A pixel connected to an n th data line includes a switching transistor that turns on in response to a selection signal supplied from a scan line; a storage capacitor to store a voltage corresponding to a data signal supplied from the n th data line when the switching transistor is turned on; and a driving transistor to supply a current corresponding to the voltage stored in the storage capacitor to the first electrode. The storage capacitor is formed between the first electrode and an (n+1) th data line.
1. A light emitting display, comprising:
a plurality of scan lines;
a plurality of data lines crossing the scan lines;
a plurality of pixels defined by the scan lines and the data lines; and
a light emitting device formed on a pixel and comprising a first electrode and a second electrode,
wherein a pixel connected to an n th data line comprises:
a switching transistor that turns on in response to a selection signal supplied from a scan line;
a storage capacitor to store a voltage corresponding to a data signal supplied from the n th data line when the switching transistor is turned on; and
a driving transistor to supply a current to the first electrode,
the storage capacitor being formed between the first electrode and an (n+1) th data line and not overlapping with the first electrode,
wherein the switching transistor and the driving transistor are arranged on a first side of the pixel, and the storage capacitor and the first electrode are arranged on a second side of the pixel,
wherein the scan line is arranged between the first side of the pixel and the second side of the pixel, and
wherein the switching transistor, the driving transistor, the storage capacitor, and the first electrode are all disposed in the same pixel.
2. The light emitting display of claim 1 , wherein the pixel connected to the n th data line further comprises:
a first parasitic capacitor between the first electrode and the n th data line; and
a second parasitic capacitor between the storage capacitor and the (n+1) th data line.
3. The light emitting display of claim 2 , wherein a distance between the first electrode and the n th data line is set so that a capacity of the first parasitic capacitor is one tenth or less of a capacity of the storage capacitor.
4. The light emitting display of claim 2 , wherein a distance between the storage capacitor and the (n+1) th data line is set so that a capacity of the second parasitic capacitor is one tenth or less of a capacity of the storage capacitor.
5. The light emitting display of claim 1 , wherein the first electrode is an anode of the light emitting device.
