发明名称 ELECTRO-OPTICAL DEVICE AND DRIVING METHOD THEREOF
摘要 An electro-optical device selects a detection target pixel independently and obtains correction data to perform a correction operation. Under a control of the electro-optical device, remaining pixels other than the detection target pixel emit light to display an image.

主权项 1. A panel, comprising: a plurality of pixels arranged in a row direction and column direction, each of the pixels including: a driving transistor having a drain electrode connected to an anode of an organic electroluminescence (EL) element,a selection transistor to control connection between a gate electrode of the driving transistor and a data signal line,a first switching transistor to control connection between a source electrode of the driving transistor and a power line for supplying current to the EL element, anda second switching transistor to control connection between the source electrode of the driving transistor and the data signal line, wherein: during a data programming period, the selection transistor is turned on and a data voltage is provided from the data signal line to the gate electrode of the driving transistor, during an emission period, the source electrode of the driving transistor of a detection target pixel is connected to the data signal line by turning off the first switching transistor and turning on the second switching transistor of the detection target pixel, so that detection current is provided to the driving transistor from the data signal line, in each of the pixels in a same row as the detection target pixel, the source electrode of the driving transistor is connected to the data signal line by turning off the first switching transistor and turning on the second switching transistor, so that a same power supply voltage on the power line is provided to the driving transistor from the data signal line, and in each of the pixels in a row different from the detection target pixel, the source electrode of the driving transistor is connected to the power line by turning on the first switching transistor and turning off the second switching transistor, so that the EL element emits light.
