3D IMAGE DISPLAY DEVICE

摘要

PURPOSE: A 3D image display device is provided to prevent a 3D cross talk by increasing the response speed of a liquid crystal and improve a MPRT(Motion Picture Response Time) without brightness lowering in a video. CONSTITUTION: A liquid crystal display panel displays a unit frame period as a cycle on a left eye image and a right eye image by turns. A data driving circuit drives data lines of a LCD panel. A gate driving circuit drives the gate lines of the LCD panel. A timing controller partitions a unit frame period into a subframe periods of N. The timing controller supplies unit frame data for subframe periods of N to data driving circuit repetition. The light source generates the light researched to the LCD panel. The light source control circuit generates a back light control signal for controlling lighting timing of light sources. A light source driving circuit altogether lights light sources in response to the back light control signal among the subframe periods of N in a final subframe period.
