Abstract
(EN)
An OLED pixel compensation circuit, and OLED display device including the pixel compensation circuit. The compensation circuit comprises a multiplexer and multiple pixel compensation sub-circuits. A connection relationship between any switch of the multiplexer and a corresponding pixel compensation sub-circuit thereof is: a first connection end of said switch receives a data voltage, a control end of said switch receives an enable signal to enable said switch to turn on in response to an active voltage of the received enable signal at the control end, and a second connection end of said switch is connected to the corresponding pixel compensation sub-circuit to provide a data voltage thereto.

Circuit de compensation de pixels OLED et dispositif d'affichage à OLED comprenant ce circuit de compensation de pixels. Le circuit de compensation comporte un multiplexeur et plusieurs sous-circuits de compensation de pixels. Une relation de connexion entre n'importe quel commutateur du multiplexeur et son sous-circuit de compensation de pixel correspondant est la suivante : une première extrémité de connexion dudit commutateur reçoit une tension de données, une extrémité de commande dudit commutateur reçoit un signal de validation pour que le commutateur se déclenche en réponse à une tension active du signal de validation reçu à l'extrémité de commande, et une seconde extrémité de connexion dudit commutateur est connectée au sous-circuit de compensation de pixel correspondant pour lui fournir une tension de données.
