摘要： A display matrix is provided for forming a composite image from a series of sub-images. In general, the display matrix includes a plurality of display elements, each display element including a pixel, and a display circuit electrically connected to the pixel. An illumination source illuminates each of the pixels. Logic controls the intensity of each pixel utilizing a digitally controlled waveform for controlling a duration of time that illumination is allowed to pass through liquid crystal of the display elements. A method for driving a digital display is also provided. Each of a plurality of pixel timers is set with an intensity value, where the pixel timers are associated with pixels of a display. The pixels of the display are set to a first state. Each of the timers is initiated. Illumination is applied to the display. Each of the pixels is switched to a second state upon expiration of the timer. The process is repeated for a predetermined number of times for generating an image. A method for producing a grayscale image on a digital display is also provided according to an embodiment of the present invention. Intensity values for each of the pixels are stored in pixel memories that are each associated with the individual pixels of a display. Each of the pixels is set to a first state. A first intensity level is broadcast to the pixels. The first intensity level is analyzed with the intensity values stored in the pixel memories. The pixels whose associated intensity value matches the first intensity level are switched to a second state. Illumination is applied to the display. A predetermined amount of time is allowed to transpire. A next intensity value is broadcasted to the pixels. The next intensity level is analyzed with the intensity values stored in the pixel memories. The pixels whose associated intensity value matches the next intensity level are switched to the second state. The final two steps of the process are repeated for each level of desired intensity.
