Abstract
A method for digital driving of an active matrix display with a predetermined frame rate is described. The display contains a plurality of pixels organized in a plurality of rows and a plurality of columns. The method includes representing each of the plurality of pixels of an image to be displayed within a frame by an n-bit digital image code. The method also includes dividing the image frame into sub-frames, which may be of substantially equal duration. Within each sub-frame, the method includes sequentially selecting at least one of the plurality of rows twice. Upon a first selection, a first digital code is written to the selected row and upon a second selection a second digital code is written to the selected row. There is a predetermined time delay between the second selection and the first selection. Digital driving circuitry is also described.

21. A method for digital driving of an active matrix display with a predetermined frame rate, the display comprising a plurality of pixels logically organized in a plurality of rows and a plurality of columns, the method comprising:
-
representing each of the plurality of pixels of an image to be displayed within a frame by an n-bit digital image code; dividing the image frame into a natural number of sub-frames; within each sub-frame, sequentially selecting at least one of the plurality of rows twice, wherein upon a first selection a first digital code is written to the selected row and upon a second selection a second digital code is written to the selected row, there being a predetermined time delay between the second selection and the first selection. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)

35. Digital driving circuitry for driving, with a predetermined frame rate, an active matrix display that includes a plurality of pixels logically organized in a plurality of rows and a plurality of columns, so as to display subsequent frames of an image to be displayed, the image being represented by an n-bit digital image code for each pixel, the digital driving circuitry comprising:
-
digital select line driving circuitry configured to sequentially select the plurality of rows; and digital data line driving circuitry configured to write the digital image code to corresponding pixels in a selected row; wherein the digital select line driving circuitry is further configured to sequentially select, within one sub-frame, at least one of the plurality of rows twice, so as to, upon a first selection, write a first digital code to the selected row and, upon a second selection, write a second digital code to the selected row, there being a predetermined time delay between the second selection and the first selection. - View Dependent Claims (36, 37, 38, 39, 40)
