A stereoscopic three-dimensional image display device is disclosed which includes: a liquid crystal display panel defined into a plurality of pixel regions; a data driver to supply data voltages to the pixel regions; a patterned retarder disposed on a front surface of the liquid crystal display panel to polarize light from the liquid crystal display panel. The patterned retarder includes a first patterned retarder, to circularly polarize light from the liquid crystal display panel in a first direction and formed in a height greater than that of a pixel region of the plurality of pixel regions, and second patterned retarder to circularly polarize light from the liquid crystal display panel in a second direction opposite the first direction and formed in a height greater than that of the pixel region.

3-dimensional image display device including a patterned retarder

Disclosed is a system and method for correcting a gamma for shortening a gamma correction time period and improving gamma correction efficiency and reliability thereof, and simplifying a gamma correction device for reducing a production cost of image display devices.

System and method for correcting gamma

A gray scale voltage generator includes a voltage dividing resistor string to generate blue (B), red (R), and green (G) gamma voltage signals, the voltage dividing resistor string including a B gamma voltage signal generating section, a R/G gamma voltage generating section, and a common (COM) gamma voltage generating section to individually control a B gray scale voltage and a R/G gray scale voltage to maintain a constant color temperature.

Data driving device and liquid crystal display device using the same

A backlight unit capable of preventing an initial driving malfunction is disclosed. The backlight unit includes a bottom cover opened upwardly, a reflective sheet disposed in the inner surface of the bottom cover; a plurality of lamps arranged at a fixed interval on the reflective sheet; an auxiliary light source disposed at the outer side surface of the bottom cover; and a light guide member, opposite to the emitting surface of the auxiliary light source, configured to guide light emitted from the auxiliary light source to the lamps through first and second penetration holes formed on one of the side walls of the bottom cover and the reflective sheet.

Backlight unit and liquid crystal display device having the same

The present invention relates to a liquid crystal device to which a line on glass structure and a cascade structure are both applied, and a manufacturing method thereof. The liquid crystal device includes: a liquid crystal panel including a plurality of pixels defined by gate lines and data lines that cross each other, wherein a first group of signal lines is formed on the liquid crystal panel in an on-glass-configuration; a plurality of tape carrier packages mounted with source drivers that provide data signals through the data lines to the liquid crystal panel and mounted on the liquid crystal panel in a cascade structure, wherein a second group of signal lines connected to the first group of signal lines is formed thereon; and a printed circuit board combined directly with only one of the plurality of tape carrier packages so as to supply a plurality of driving signals and control signals to the liquid crystal panel.
