Patent ID: 7245276

Claim:
An electro-optical apparatus, comprising: a pixel matrix in which pixels including light-emitting devices are disposed in a matrix; a plurality of scanning lines respectively connected to pixel groups disposed in one of a row direction and a column direction of the pixel matrix; a plurality of data lines respectively connected to pixel groups disposed in the other one of the row direction and the column direction of the pixel matrix; a scanning-line drive circuit connected to the plurality of scanning lines so as to select one row or one column of the pixel matrix; and a data-line drive circuit to generate, based on a digital signal, a control signal having a current value in accordance with a light-emission grayscale of the light-emitting device, and to output the generated control signal to at least one of said plurality of data lines in a predetermined period, the data-line drive circuit including a first current-value setting device to set the current value of the control signal in each first period, which is provided in the predetermined period, and a second current-value setting device to adjust the current value of the control signal in each second period, which is provided plurally in the predetermined period, and is different from the first period, and is shorter than the first period; the first current-value setting device setting the current value of the control signal in each of the first period based on part of digital data forming the digital signal; and the second current-value setting device adjusting the current value of the control signal in each of the second period based on the remaining data other than the part of the digital data used by the first current-value setting device for a portion set by the first current-value setting device based on the same digital data of the control signal.
