Abstract
(EN)
A pixel circuit and an OLED display panel. The pixel circuit comprises: a driving circuit (31), a light emitting circuit (32), a switch circuit (33), a first storage circuit (34), and a second storage circuit (35), wherein the second storage circuit (35) is used for charging in a light-emitting stage of a first display frame under the control of the switch circuit (33) and providing a working voltage for the driving circuit (31) in the case of a second display frame so as to trigger the driving circuit (31) to drive the light-emitting circuit (32) to emit light.
(FR)
L’invention concerne un circuit de pixels et un panneau d’affichage à DELO. Le circuit de pixels comprend : un circuit d'attaque (31), un circuit d'émission de lumière (32), un circuit de commutation (33), un premier circuit de stockage (34) et un second circuit de stockage (35), le second circuit de stockage (35) étant utilisé pour effectuer un chargement dans une phase d'émission de lumière d'une première trame d'affichage sous la commande du circuit de commutation (33) et fournir une tension de travail pour le circuit d'attaque (31) dans le cas d'une seconde trame d'affichage de façon à déclencher le circuit d'attaque (31) pour amener le circuit électroluminescent (32) à émettre de la lumière.
