Abstract: 디스플레이는둥근코너들과같은만곡형에지들을가질수 있다. 디스플레이의픽셀들은디스플레이의활성영역이원하는만곡형에지형상을갖도록제어될수 있다. 만곡형에지의겉보기매끄러움을최대화하기위해, 디스플레이는만곡형에지에대한스플라인에대한픽셀들의위치에기초하여픽셀들의일부를디밍하는회로부를포함할수 있다. 디스플레이회로부는제1 입력으로서이미지데이터를수신하고제2 입력으로서이득테이블로부터디밍인자들을수신하는승산회로를포함할수 있다. 이미지데이터는픽셀들의어레이의각각의픽셀에대한밝기레벨을포함할수 있다. 승산회로는각각의픽셀에대한밝기레벨과그의개개의디밍인자를곱할수 있다. 이수정된이미지데이터는이어서디스플레이드라이버회로부를사용하여이미징픽셀들에공급될수 있다.

Abstract: Abstract A display may have an array of organic light-emitting diode display pixels. Each display pixel may include a drive transistor coupled in series with one or more emission transistors and a respective organic light-emitting diode (OLED). A semiconducting-oxide transistor may be coupled between a drain terminal and a gate terminal of the drive transistor to help reduce leakage during low-refresh-rate display operations. To compensate for variations in the threshold voltage of the semiconducting-oxide transistor, the magnitude of a high voltage level of a scan control signal provided to the gate terminal of the semiconducting-oxide transistor may be adjusted. Sensing circuitry may be used to sense a display current while displaying a calibration image. The sensed display current may be compared to an expected display current associated with the calibration image. Processing circuitry may update the high voltage level based on the actual display current compared to the expected display current.
