Abstract (en)
[origin: WO02069259A2] 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 (1014), each display element including a pixel, and a display circuit electrically connected to the pixel. An illumination source (3002) illuminates each of the pixels. Logic controls (3016) 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 (3014). Intensity values for each pixels are stored in memories (3006,3010) that are 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 (3004) with the intensity value stored in the pixel memories (3006,3010).
