Patent ID: 8884852

Claim:
A display device comprising: a pixel circuit that includes at least one capacitive component and at least one switching component; a signal line disposed in a form of a column on a pixel array where the pixel array is arranged in a form of a matrix; at least one scanning line disposed in a form of a row on the pixel array; a signal line driving section configured to output a plurality of signal potentials to the signal line within one horizontal period, each respective value of the plurality of signal potentials being variably selected from among a plurality of potential values based on an input video signal; and a scanning line driving section configured to cause the at least one switching component of the pixel circuit to sequentially introduce each of the plurality of signal potentials into the capacitive component of the pixel circuit within the one horizontal period by driving the at least one scanning line, wherein the pixel circuit is configured such that the plurality of signal potentials that are sequentially input to the capacitive component are synthesized, thereby generating a display value, the display value corresponding to the value of one of the plurality of signal potentials plus a change amount, the change amount being proportional to a difference between respective values of at least two of the plurality of signal potentials, and the pixel circuit is configured to display at a gradation corresponding to the display value, wherein the plurality of signal potentials includes at least a first signal potential and a second signal potential, values of both the first and second signal potentials being variably selected based on an input video signal, and the pixel circuit generates the display value by synthesizing the first signal potential and the second signal potential input within the one horizontal period, the display value corresponding to the value of the first signal potential plus the change amount, the change amount being proportional to a difference between the value of the first signal potential and the value of the second signal potential multiplied by a constant corresponding to a ratio between capacitances present within the pixel circuit.
