摘要： A driving circuit includes: a plurality of scan stages each corresponds to a plurality of scan lines, receives clock signals and a carry signal, and outputs a scan signal; and a plurality of masking circuits corresponding to some scan stages, respectively, among the scan stages. each masking circuit outputs one of the scan signal output from a corresponding scan stage and a first voltage as a masking carry signal in response to a masking signal. A j-th scan stage receives a scan signal output from a (j−a)th scan stage as the carry signal when the (j−a)th scan stage is not one of the some first scan stages, and the masking carry signal output from a masking circuit corresponding to the (j−a)th scan stage as the carry signal when the (j−a)th scan stage is one of the some first scan stages.

摘要： A pixel includes a light emitting element, a data write switching element, a driving switching element, a light emitting element initialization switching element and a boosting capacitor. The data write switching element is configured to receive a data voltage from the outside. The driving switching element is configured to apply a driving current to the light emitting element based on the data voltage. The light emitting element initialization switching element is configured to apply an initialization voltage to a first electrode of the light emitting element. The boosting capacitor includes a first electrode connected to a control electrode of the light emitting element initialization switching element and a second electrode connected to an output electrode of the data write switching element.

摘要： A display device includes: scan lines extending in a first direction; data lines extending in a second direction intersecting the first direction and receiving data voltages; first driving voltage lines extending in the second direction and receiving a first driving voltage; second driving voltage lines extending in the second direction and receiving a second driving voltage different from the first driving voltage; and pixels connected to the scan and data lines. Each of the pixels includes first, second, and third subpixels arranged in the first direction. The first driving voltage lines and the second driving voltage lines are alternately arranged in the first direction. A location of the first driving voltage line in a first pixel differs from a location of the second driving voltage line in a second pixel. The second pixel is adjacent to the first pixel in the first direction.
