1. A liquid crystal display device comprising:
a plurality of pixels individually provided at an intersecting portion at which a plurality of column data lines intersects with a plurality of row scanning lines,
each of the pixels individually including:a display element configured to have liquid crystals filled and sealed between a pixel electrode and a common electrode opposing to each other;a first switching unit configured to sample subframe data for displaying every frame of a video signal in a plurality of subframes having a display period shorter than one frame period of the video signal through the column data line;a first signal holding unit configured to form a static random access memory together with the first switching unit and configured to store the subframe data sampled by the first switching unit, one first signal holding unit being provided for one display element;a second switching unit configured to output the subframe data stored in the first signal holding unit; anda second signal holding unit configured to form a dynamic random access memory together with the second switching unit, in which stored content is rewritten with the subframe data stored in the first signal holding unit supplied through the second switching unit, and configured to apply output data to the pixel electrode; and a pixel control unit configured to perform, for individual subframes, operations of:
after writing into all of the plurality of pixels, which configures an image display unit, by repeatedly writing the subframe data to the first signal holding unit for the individual pixels in units of rows;turning on the second switching units in all of the plurality of pixels with a trigger pulse; andrewriting stored content in the second signal holding units of the plurality of pixels with the subframe data stored in the first signal holding unit. |
