摘要： A gamma-correction circuit is formed by a switch circuit (52) for receiving a reset pulse and connecting a terminal pin (XR) to a predetermined potential line, a correction data generation circuit (7) for generating correction data (TDi) for correcting a light emission period in accordance with display data in order to subject the luminance of an OEL element (9) to the gamma-correction, and a reset pulse generation circuit (51) for receiving a timing control signal (TP) and the correction data (TDi) and generating a reset pulse of the pulse width corresponding to the gamma-correction. By providing the gamma-correction circuit corresponding to the terminal pin (XR), it is possible to suppress the area occupied by the organic EL drive circuit and the gamma-correction circuit of the organic EL display device.

摘要： An organic EL display device (10) is provided with first and second drivers (1, 2), a multitude of switching circuits (US, DS) and a control circuit (5). The first and second drivers are provided with a multitude of output terminals (P). The multitude of switching circuits alternately connect n-number of the output terminal(s) of the first driver (1) (n is an integer of 1 or more) with one and the other of driving lines, which are of the 2n number of organic EL elements and are divided into two, and alternately connect n-number of the output terminal(s) of the second driver (2) with the remaining n-number of the other and the one of the driving lines. The control circuit (5) controls the multitude of switching circuits to switch at the same time by generating a control signal by m frame(s) (m is an integer of 1 or more) or by m horizontal line(s). Thus, brightness variation and brightness nonuniformity can be reduced.
