The autostereoscopic 3D display can include a display panel including a plurality of pixels; a plurality of lenticular lens disposed on a front surface of the display panel and having a slanted axis; a position detector measuring the distance of an observer from the display panel; and a view-map selector selecting one of view-maps in accordance with the distance of the observer from the display panel.

Autostereoscopic 3-dimensional display

Provided is a stereoscopic image display device comprising a display panel displaying a multi-view image in a three-dimensional (3D) mode, a switchable barrier forming a barrier in the 3D mode, a user position detecting unit outputting a user position data including a user position information, a switchable barrier controlling unit calculating an average picture level of the multi-view image in the 3D mode and controlling an aperture ratio of the switchable barrier according to the average picture level and the user position information, a switchable barrier driving unit supplying driving voltages to divided electrodes of the switchable barrier and supplying a common voltage to a barrier common electrode, and a display panel driving unit converting the multi-view image into data voltages to supply the data voltages to data lines of the display panel and sequentially supplying gate pulses to gate lines of the display panel.

Stereoscopic image display device and method for driving the same

The embodiments herein provide a stereoscopic image display device and method for driving the same capable of improving 2D image quality. The stereoscopic image display device comprises a display panel including a plurality of pixels; a 2D data converter configured to received two-dimensional data for each of a plurality of sub-pixels of the pixels and to convert the 2D data for each of the plurality of sub-pixels into converted 2D data for each of the plurality of sub-pixels based on all of the 2D data for the plurality of sub-pixels; and a display panel driving circuit configured to receive the converted 2D data for each of the plurality of sub-pixels and to supply each of the converted 2D data to a corresponding one of the plurality of sub-pixels in a two-dimensional mode of the stereoscopic image display device.

An image data processing method comprises: extracting a depth map from an input image; separating the input image into a foreground area and a background area based on grayscales of the depth map; and modulating the maximum depth value of the input image to become smaller and the difference between depth values of a gray grayscale segment of the depth map to be greater than the difference between depth values of the foreground area and background area of the input image.

Image data processing method and stereoscopic image display using the same

This embodiments herein relate to an image processing method and a stereoscopic image display device that provide high readability of a text area when implementing both 2D images and 3D images. The embodiments described herein convert the left(right)-eye image data corresponding to the left(right)-eye coordinates into a mean of the left(right)-eye image data corresponding to the left(right)-eye coordinates and the left(right)-eye image data adjacent to thereof on the other line. Therefore, the embodiments described herein may compensate for the left(right)-eye conversion data which are not arranged on a 3D format. As a result, the embodiments described herein may improve readability of the text area in the 3D mode. Also, the embodiments described herein may improve readability on the text area by applying a sharpness filter to the original 2D image corresponding to the 2D coordinates which is detected as the text area in the 2D mode.

Image processing method, image processor and stereoscopic image display device using the image processor

A stereoscopic image display device and method of removing jagging of a stereoscopic image. The method comprises: detecting left edges and right edges by analyzing left-eye image data and right-eye image data; detecting a row line as a complicated line if a number of the left edges or the right edges in the row line is equal to or more than a complicated line threshold value, and counting a number of complicated lines; generating a complexity signal having a first logic level if the number of the complicated lines is equal to or more than a complexity detection threshold value; and generating the complexity signal having a second logic level if the number of the complicated lines is less than the complexity detection threshold value.
