摘要： A novel method for driving a display device includes the steps of receiving video data of a first type, converting the video data to data of a second type, dithering the data of the second type to form dithered pixel data, and outputting the dithered pixel data. The step of converting the video data to data of a second type includes inserting dither bits indicative of a particular dithering scheme into the data of the second type. An example display driver circuit includes an input for receiving video data, a data converter coupled to receive the video data and operative to convert the video data into pixel data to be written to pixels of a display, and a ditherer operative to receive the pixel data and to dither the pixel data to generate dithered pixel data. The video data is data of a first type, and the pixel data is data of a second type, different from the first type. In the disclosed example, the first type of data includes a binary data word, and the second type of data includes a compound data word. The compound data word includes a first set of binary weighted bits, a second set of arbitrarily weighted bits, and dither bits.

摘要： A novel method for driving a display having an array of pixels arranged in a plurality of columns and a plurality of rows includes the steps of defining a modulation period for a row of pixels, dividing the modulation period into a number of coequal time intervals equal to n times the number of rows in the array, receiving a multi-bit data word that indicates an intensity value, and updating the signal asserted on the pixel during a plurality of the time intervals such that the intensity value is displayed by the pixel. Note that n is an integer greater than zero. The method can be applied to all rows, which can be driven asynchronously. A display driver for performing the novel methods is also disclosed. The present invention facilitates driving the display at 100% bandwidth efficiency during each time interval in the modulation period.
