Abstract: A pixel circuit includes a pixel unit and a memory circuit. The memory circuit includes a first switch, a switch unit, a second switch, and a plurality of memory units. Each of the memory units includes a third switch and a capacitor, where the capacitors of the memory units have a same capacitance. A data accessing method applied on the pixel circuit includes determining an order of writing a plurality of first voltages, which are loaded from a data line, according to weights of bits within a first bit string, where the bits are respectively corresponding to the first voltages, and includes determining an order and loading durations of loading a plurality of second voltages, which are previously stored in the memory units, according to weights of bits within a second bit string, where the bits are respectively corresponding to the second voltages.
