ABSTRACT:
A display device and a method of driving liquid crystals in an array of pixels of the display device include providing dual port memory cells that isolate write operations to the pixels from read operations within the pixels. Preferably, each pixel has an array of integrated dual port memory cells, with the number of cells in the array being equal to the number of bits per pixel within each frame of pixel data. The dual port memory cell may be an electrical series connection of a bit-storage device having write access circuitry (e.g., a write access transistor) on one side and read access circuitry (e.g., two read access transistors) on the opposite side. Such a series connection of devices enables the rate of driving the liquid crystal to be set independently from the rate of receiving pixel data at the pixels.
