Abstract: Disclosed relates to an LCD panel driving device that improves power input ends for inputting driving signals and connection patterns of the LCD panel driving device and the LCD panel, thus eliminating a block dim phenomenon generated when driving the LCD panel. The LCD driving device connected electrically with conductive patterns formed on a lower glass of an LCD and outputting driving signals for driving the LCD panel based on driving signals input from the conductive patterns, the LCD driving device of the invention comprising: a plurality of first input bumps for inputting driving signals; and a plurality of second input bumps coupled electrically with the first input bumps, respectively, at least two of the first input bumps being connected with each other via resistors having at least two different resistance values.

Abstract: The present invention relates to a driving integrated circuit IC for driving a liquid crystal display LCD and, more particularly, to an LCD panel driving device and a circuit array using the same, which simplifies the circuit array and reduces its manufacturing cost. The LCD panel driving device of the invention comprises output bumps 311 for outputting driving signals to the LCD panel and at least an input bump group 312 arranged in a perpendicular direction with the output bumps 311. The input bumps are coupled electrically with conductive patterns 32 formed on a base film 30 or a lower glass 1.
