摘要： A demultiplexer circuit selects one of data signals, which are sent via an output port of a data driver circuit, on a time division basis, and distributes the data signals to data lines. For high-resolution display, the demultiplexer sequentially distributes data signals to associated data lines. For low-resolution display, the demultiplexer distributes identical data signals to data lines or parts of the data lines. Gate driver circuits each sequentially drive scan lines for high-resolution display, and concurrently or temporarily concurrently drive the scan lines for low-resolution display.

摘要： In RGB time division drives, there is capacitor coupling due to the effects of fluctuation in the drain lines, and thus, the image quality deteriorates (lateral smearing), so that the display brightness becomes different from the desired display brightness due to delay in the convergence of the fluctuation of the common potential, and thus, it is a goal to prevent the image quality from deteriorating (lateral smearing). In RGB time division drives, the order of time division is switched for each frame, or in the direction of the horizontal lines.

摘要： A processing portion for conversion from RGB to RGBW includes a W generating circuit, a sub-pixel rendering circuit, a W intensity calculating portion which transmits a W intensity setting value to a W generating circuit, and a low power backlight control circuit which expands data on the basis of the RGBW pixels generated by the sub-pixel rendering portion and lowers the backlight in accordance with the amount by which the data is expanded. The inputted RGB data is used as the RGBW data with the W intensity calculated by the W intensity calculating portion. A backlight control signal is generated based on the amount of data expansion in the sub-pixel rendering portion. Deterioration (darkness) of image quality due to a reduction in the brightness of a single color as a result of the conversion from RGB pixels to RGBW pixels is prevented and a reduction in the power is achieved.
