Abstract
Official abstract text for this publication.
A stereoscopic image display device includes a liquid crystal display panel on which frame data is addressed, a frame rate conversion unit that divides 3D input data into left eye image data and right eye image data, and inserts reset frame data including black grayscale data between the left eye image data and the right eye image data, and a luminance difference compensation unit that generates compensation values for compensating a luminance difference depending on positions in a screen of the liquid crystal display panel, wherein a compensation value added to the left eye image data and the right eye image data to be displayed on an upper part of the screen of the liquid crystal display panel is higher than a compensation value added to the left eye image data and the right eye image data to be displayed under the upper part of the screen.
First claim
Opening claim text (preview).
What is claimed is: 1. A stereoscopic image display device, comprising: a liquid crystal display panel on which frame data is addressed in order of a (n+1)-th frame data to a (n+4)-th frame data, n being a positive integer; a frame rate conversion unit that divides 3D input data into left eye image data and right eye image data, and inserts reset frame data including black grayscale data between the left eye image data and the right eye image data, thereby generating the (n+1)-t…
