摘要： A display system comprises an interface circuit (706) for receiving various data from a network (704) to output to a downstream circuit system; a data separation circuit (708) to separate from data outputted from the interface circuit (706) still picture file and moving picture file concerning image and control data; an output control circuit (710) (control for still picture and control for moving picture) for a display controller (228), for example, in a unit of display component (14), on the basis of the control data from the data separation circuit (708); and a compressed file decoder circuit (712) installed upstream from an image data-processing circuit (224), for expanding the compressed file image to restore into still picture data and moving picture data.

摘要： A display system includes a light guide plate for transmitting light therethrough, and a panel portion arranged opposite to a back of said light guide plate. The panel portion includes a driving portion provided with actuators of the number corresponding to that of a number of pixels. The panel portion causes a video image to be displayed on the light guide plate according to an inputted image signal, by introducing light into the light guide plate and controlling displacement operations in contact and separation directions of the actuators with respect to the light guide plate according to properties of the image signal, and thereby controlling leakage light in a predetermined region of the light guide plate. The display system further includes a cooling device for controlling flow of a fluid in contact with the back of the light guide plate, to cool the light guide plate from its backside.
