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.

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.

A signal voltage is written in the pixel electrode I when the gate line G1a is in the “on” state, a signal voltage is written in the pixel electrode II when the gate line G1b is in the “on” state, and a signal voltage is written in the pixel electrode III when the gate lines G1a and G1b are both in the “on” state. Signal voltages are written in the pixel electrodes III, I and II in this order mentioned.
