DISPLAY DEVICE

When transparency information (T) is externally inputted along with RGB image data (DV1), the RGB image data (DV1) is converted to YUV image data (DV2) in YUV422 formal, and the transparency information (T) is added to information about a color-difference component U or V therein, thereby generating...

Zusammenfassung:	When transparency information (T) is externally inputted along with RGB image data (DV1), the RGB image data (DV1) is converted to YUV image data (DV2) in YUV422 formal, and the transparency information (T) is added to information about a color-difference component U or V therein, thereby generating YUV image data (DV3) to be inputted to a signal processing portion (20). The signal processing portion 20 extracts the transparency information (T) and converts the YUV image data (DV2) to RGB image data (DV1). When the RGB image data (DV1) and the transparency information (T) are inputted to an LCD timing controller (30). the LCD timing controller 30 renders a liquid crystal display panel (90) transparent on the basis of the transparency information (T). thereby allowing background light to be transmitted therethrough, or when only the RGB image data (DV1) is inputted, the liquid crystal display panel (90) displays an image.
