Abstract: A display method used for a display which has a backlight module suitable to provide more than M types of primary color lights, where M=3. The display panel of the display has an array of pixel regions. The display method provides these pixels regions to display multiple image data to be display in multiple frame times. Each of the image data includes (L1N, L2N, . . . , LMN) each representing the brightness of the M primary color light in each pixel region, where N is a positive integer. The backlight module sequentially provides M-1 primary color lights within any two successive frame times, so allow the image data to drive the pixel regions. The first and the Mth primary color lights provide the frame times for these two successive frame times.
Abstract: A light emitting diode (LED) circuit includes first and second terminals, a forward circuit including a number of LEDs electrically connected in series, and a forward steering diode electrically connected in series with the LEDs. The series combination of the forward steering diode and the LEDs is electrically connected between the first and second terminals, and is structured to conduct current in a first direction with respect to the first and second terminals in order to illuminate the LEDs. A reverse circuit includes a resistor, and a reverse steering diode electrically connected in series with the resistor. The series combination of the reverse steering diode and the resistor is electrically connected between the first and second terminals, and is structured to conduct current in an opposite second direction with respect to the first and second terminals such that the LEDs are not illuminated. An LED drive circuit is also disclosed.
Abstract: A source driver for driving a source line included in an electro-optical device, includes: an impedance conversion circuit which drives the source line based on a grayscale voltage corresponding to display data; a first switch circuit including one end to which a non-display voltage is supplied and another end coupled to an output of the impedance conversion circuit; a power save data holding circuit provided corresponding to each impedance conversion circuit or to impedance conversion circuits corresponding to a plurality of dots making up a pixel, and for holding power save data; and a first mask circuit for masking the power save data based on a first mask control signal that varies in unit of a horizontal scan period.
