Abstract
A source driver integrated circuit comprises a common node; a plurality of pads for inputting power, a portion of which are connected to an external power source and the remainder of which are connected to the portion through the common node; and a common power line which is connected to the plurality of power input pads through the common node. As a result, the resolution of adjacent channels varies very little and block dimming between channels can be resolved.
Claims14
A source driver integrated circuit comprising:
- a plurality of pads for inputting power, a portion of the pads being directly connected to an external power source, a remainder of the pads being indirectly connected to the external power source;
- an internal power line that connects the plurality of pads for inputting power to each other;
- a common power line that connects a plurality of panel driving circuits to each other;
- and
- a common node that connects a substantial center point of the internal power line to a substantial center point of the common power line.
