Abstract

A liquid crystal display (LCD) device with a register-type gamma reference voltage generating unit inside a data driving IC, thus to remove a source block dim phenomenon in a Chip on Glass (COG) cascade structure, and a driving method thereof. The LCD device comprises an LCD panel on which a plurality of gate lines and data lines intersect with each other. A TFT is formed at each intersection, to thus define images. A data driving unit supplies a gradation voltage to the LCD panel through a gamma voltage generating unit. A gate driving unit supplies a gate pulse to each gate line on the LCD panel. A timing controller controls the gate driving unit, the data driving unit and the gamma voltage generating unit.

Description

[0001] The present application relates to the contents of a prior Korean Application No. 10-2006-0061634 filed on Jun. 30, 2006, which is incorporated herein by reference in its entirety. technical field

[0002] The present invention relates to a liquid crystal display device, in particular to a liquid crystal display device having a register-type gamma (gamma) reference voltage generating unit in a data driving IC and a driving method thereof, thereby achieving a chip-on-glass (COG) level Remove the source block dimphenomenon from the link structure. Background technique

[0003] Generally, a liquid crystal display (LCD) device has optical anisotropy, which obtains a certain direction when the liquid crystal is arranged in a thin and long molecular structure, and the liquid crystal display device has a polarization state, when the liquid crystal is arranged in an electric field, the molecular arrangement direction depends on the magnitude of the electric field Variety. ...
