    • A stereoscopic image display device comprises a frame rate conversion unit that divides 3D input data into left eye image data and right eye image data, inserts reset frame data containing black grayscale data between the left eye image data and the right eye image data, and generates the (n+1)-th frame data to the (n+4)-th frame data containing the left eye image data, the black grayscale data, the right eye image data, respectively, and the black grayscale data, a look-up table that stores local dimming values used to control brightness for the overall local dimming zones to the minimum during the (n+2)-th and (n+4)-th frame periods, and local dimming values used to control brightness for each local dimming zone to target brightness during the (n+1)-th and (n+3)-th frame periods, and a backlight controller that controls light source brightness of the backlight unit for each local dimming zone.
    • 立体图像显示装置包括将3D输入数据分割为左眼图像数据和右眼图像数据的帧率转换单元,在左眼图像数据和右眼图像数据之间插入包含黑色灰度数据的复位帧数据,并生成 第(n + 1)帧数据分别包含左眼图像数据,黑色灰度数据,右眼图像数据和黑色灰度数据的第(n + 4)帧数据, 将在第(n + 2)和第(n + 4)帧周期期间将用于将整个局部调光区域的亮度控制到最小的局部调光值存储在一起,以及用于控制每个 在第(n + 1)和第(n + 3)帧周期期间的目标亮度的局部调光区域以及控制每个局部调光区域的背光单元的光源亮度的背光控制器。
