摘要： A liquid crystal display includes: a light source section including emission subsections; a LCD panel including pixels each having sub-pixels for four colors of R, G, B, and Z, and modulating light from the emission subsections based on input image signals for three colors of R, G, and B; and a display control section including a partitioning-drive processing section, driving the emission subsections with an emission pattern signal, and driving the four sub-pixels with partitioning-drive image signals for the four colors. The partitioning-drive processing section generates pixel signals for the four colors through performing a first color-conversion based on the input image signals, generates the emission pattern signal from pixel signals for the three colors, primary partitioning-drive image signals for the three colors from both the input image signals and the emission pattern signal, and the partitioning-drive image signals through performing a second color-conversion on the primary partitioning-drive image signals.

摘要： A liquid crystal display includes: a light source section including light emission subsections; a liquid crystal display panel modulating, based on an input picture signal, light emitted from each light emission subsection to display pictures through switching of picture streams from one to another in order; and a display control section including a divisional-drive processing section generating a light emission pattern signal for the light emission subsections and a divisional-drive picture signal based on the input picture signal. The display control section performs a light emission drive on the light emission subsection with use of the light emission pattern signal and performs a display drive on the liquid crystal display panel with use of the divisional-drive picture signal. The divisional-drive processing section determines a logical-OR picture of the picture streams, and generates the light emission pattern signal and the divisional-drive picture signal with use of the logical-OR picture.

摘要： A liquid crystal display device including: a light source section including emission subsections; a LCD panel; and a display control section having a partitioning-drive processing section which generates an emission-pattern signal and a partitioning-drive image signal based on the input image signal. The display control section performs light-emission drive on each emission subsection based on the emission-pattern signal, and performs display-drive on the LCD panel based on the partitioning-drive image signal. The partitioning-drive processing section generates a primary emission-pattern signal corresponding to a primary pattern formed from lighting emission subsections based on the input image signal, performs a first frame-rate-increasing conversion on the primary emission-pattern signal to create the emission-pattern signal, performs a second frame-rate-increasing conversion on the input image signal by frame interpolation method with motion compensation, and generates the partitioning-drive image signal, based on the emission-pattern signal and the resultant of the second frame-rate-increasing conversion.
