Abstract:
A portable display system comprising:a housing having a volume of less than 300 cm3; a color sequential liquid crystal display mounted to the housing, the color sequential liquid crystal display including an array of pixel electrodes in a first plane, and a counter electrode panel extending ina second plane that is parallel to the first plane; a light source positioned within the housing to illuminate the array of pixel electrodes; a lens that focuses an image on the display for viewing by a user; an audio transducer device mounted to the housing that generates an audio sound; a memory card reader positioned within the housing that receives input to be displayed on the display from a memory card that docks with the card reader; and a display circuit that generates images from the input to be displayed on the liquid crystal display and connected to the liquid crystal display, the counter electrode panel receiving an applied voltage such that the display circuit actuates the pixel electrodes to write an image, flashes the light source to illuminate the image, and switches the applied voltage to the counter electrode to erase the image.
