Abstract

The invention discloses a drive circuit for display device which comprises a driving integrated circuit configured to generate various signals needed to display images on a panel display unit; a surface mounting type package including a mounting region, a plurality of input patterns and a plurality of output pattern; a logic power input pattern configured to transmit the logic power from externalsystems; a logic input pin connected to the logic power input pattern; a logic power transmission line connected with the logically power input pin for transmitting logic power; a plurality of data driving units connected with the logic power transmission line by parallel while operated by the logic power from the logic power transmission line; external auxiliary transmission lines with each one side connected with each logic power input pattern; internal auxiliary transmission lines with each one end connected with one or each of the plurality of data driving units; and auxiliary input pins configured to connected with the other side of the internal auxiliary transmission line or the other side of the external auxiliary transmission line.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2009-0091234 filed Sep. 25, 2009, which is hereby incorporated by reference in its entirety as if fully set forth herein. technical field [0002] The present invention relates to a driving circuit for a display device, and more particularly, to a driving circuit for a display device capable of preventing the A block dim phenomenon and a noise phenomenon occur at edges in order to improve image quality. Background technique [0003] The driving integrated circuit includes a plurality of data driving units for providing image data to the data lines of the panel. These data drive units are driven by received logic power. Compared with the rest of the data driving units, the logic power supplied to the data driving unit farthest from the input pin supplying the logic power among the data driving units is significantly distorted. Therefore, the image data output from the data driving unit located at...
