摘要： In a pixel circuit formed by using a MOS process, a constant current is applied from a second transistor (T2) as a constant current source to an organic EL device coupled to a third transistor (T3) so that the organic EL device emits light, during the period when the third transistor (T3) is in the conductive state. The third transistor (T3) is switched on and off based on its gate voltage dependent upon a signal value written to a capacitor (Cs) and a ramp signal voltage (Vcs). Thus, the organic EL device emits light during the period dependent upon the signal value. That is, displaying operation is implemented with gray-scale being controlled according to a video signal value.

摘要： An organic electroluminescent display device includes scanning lines, signal lines, and pixels formed in a matrix, each pixel being at an intersection of each of the scanning lines and each of the signal lines. Each pixel includes a light-emitting element, a light-emitting circuit composed of a thin-film transistor, and a light-receiving circuit composed of a thin-film transistor. When the light-emitting circuit is selected by the scanning line, the light-emitting circuit drives the light-emitting element according to a video signal that is input from the signal line, thereby displaying an image on the pixels formed in the matrix. The light-receiving circuit is selected in a period of time during which the light-emitting circuit does not operate, and outputs a light-receiving signal in accordance with the amount of light incident on the pixel to a different signal line.

摘要： A plurality of scanning periods are combined to form a composite period (2H). Within the first period of the front half, threshold value (Vth) correction is carried out all at once, and within the second period of the latter half, signal (Vsig) writing operation is carried out. High speed writing can be carried out even where the scanning period is shortened.
