摘要： The 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.A processing portion for conversion from RGB to RGBW 106 is formed of a W generating circuit 201, which is the same as in the prior art, a sub-pixel rendering circuit 202, a W intensity calculating portion 203 which transmits a W intensity setting value 205 to a W generating circuit 201, and a low power backlight control circuit 204 which expands data on the basis of the RGBW pixels generated by the sub-pixel rendering portion 202 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 203. A backlight control signal is generated in accordance with the amount of data expansion in the sub-pixel rendering portion 202.

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： An object of the present invention is to provide a signal line driving circuit capable of easily and optimally adjusting the gamma characteristics of R, G, and B self-emitting element groups (e.g., organic EL element groups) such that each gamma characteristic matches the characteristics of the self-emitting panel by accommodating variations among the characteristics of the R, G, and B self-emitting element groups, thereby providing enhanced image quality and versatility.A self-emitting display driving circuit (a signal line driving circuit) 302 includes 3 gray-scale voltage generating circuits 311 and 3 control registers 308 for R, G, and B self-emitting element groups, respectively, and these gray-scale voltage generating circuits and control registers can be adjusted separately. This arrangement makes it possible to accommodate variations among the characteristics of the R, G, and B self-emitting element groups and thereby provide enhanced image quality on the self-emitting display.
