A method of controlling a liquid crystal display (LCD) device including an LCD panel and an edge-type backlight unit is provided. The method includes: controlling turn-on and turn-off periods of an upper light source unit and a lower light source unit of the edge-type backlight unit to be synchronized with a period during which a 3D image is output on the LCD panel, wherein the upper light source unit includes a light source disposed at an upper edge of the edge-type backlight unit, and the lower light source unit includes a light source disposed at a lower edge of the edge-type backlight unit.

Methods and apparatuses are provided for compensating for a temperature of a liquid crystal display (LCD) panel. The method includes selecting a lookup table corresponding to a detected temperature of the LCD panel from among lookup tables for a 3-dimensional (3D) display of the LCD panel; and adjusting luminance to be output to the LCD panel based on the selected lookup table.

Provided are methods and apparatuses for displaying a stereoscopic image. The method includes alternately generating repeated left-eye images and repeated right-eye images; turning off a backlight unit during a period in which a left-eye image and a right-eye image are mixed and turning on the backlight unit during a period in which only one of the left-eye and right-eye images is displayed; and controlling a left-eye shutter and a right-eye shutter of shutter glasses during a period in which the backlight unit is turned on.

An image display method includes alternately receiving left and right images of a 3D image; and turning on a backlight such that the backlight is on only in periods when the left images are displayed or only in periods when the right images are displayed. A method of controlling shutter glasses separately for left and right images of a three-dimensional (3D) image includes alternately receiving the left and right images of the 3D image; and opening two shutters of the shutter glasses only in periods when the left images are received or only in periods when the right images are received.

A method and apparatus for controlling a backlight unit of a three-dimensional (3D) display apparatus receiving a 3D video sequence is provided. The method includes determining the image brightness level of the 3D video sequence displayed on a liquid crystal display (LCD) unit, for each of a plurality of partial regions of the LCD unit to which a plurality of sub-blocks of the backlight unit emit light; determining turn-on times of the plurality of sub-blocks of the backlight unit, based on the image brightness of each of the partial regions of the LCD unit; and determining turn-on periods of the plurality of sub-blocks of the backlight unit by synchronizing with a switching period between a set including a left visual point frame and a right visual point frame of the 3D video sequence.

A display apparatus which displays two-dimensional (2D) and three-dimensional (3D) images and a method of driving the same. In the 2D/3D image display apparatus, an image signal input unit inputs, to a display panel, a left image signal, a left inversion image signal, at least one 2D image signal, a right image signal and a right inversion image signal, a left shutter of shutter glasses is open in synchronization with the left image signal, a right shutter of the shutter glasses is open in synchronization with the right image signal, and the left shutter and the right shutter of the shutter glasses are closed in synchronization with the left inversion image signal, the at least one 2D image signal, and the right inversion image signal.
摘要:
A stereoscopic display apparatus is provided. The display apparatus includes a display panel for scanning an image alternately at a first frame frequency and a second frame frequency, different from the first frame frequency, an image signal input unit for inputting an image signal to the display panel, a backlight unit for emitting light to the display panel, and a shutter controller for selectively controlling an opening and closing of a left eye shutter and a right eye shutter of shutter glasses.

A stereoscopic display apparatus includes a display panel which scans an image at a frame frequency that is an odd-numbered multiple of a field frequency, an image signal input unit which inputs an image signal to the display panel, a backlight unit which emits light to the display panel, and a shutter controller which controls an opening and a closing of a left eye shutter and a right eye shutter of shutter glasses.
摘要:
An image signal processing device, a display apparatus, and a display method are provided. The image signal processing device includes: a light source driver which turns on a plurality of light sources providing different colors, in a given order; a sub-frame calculator which divides a frame of an input image signal into a plurality of sub-frames; a display processor which sequentially outputs the plurality of sub-frames on a display panel; and a sync signal processor which outputs a sync signal to the backlight driver to turn on the plurality of light sources in each of the plurality of sub-frames, in the given order.
