PIXEL CIRCUIT, A DISPLAY DEVICE, AN ELECTRONIC DEVICE AND A DRIVING METHOD OF THE PIXEL CIRCUIT FOR PROVIDING A CURRENT TO A STORAGE CAPACITY THROUGH A DRIVING TRANSISTOR

摘要

PURPOSE: A pixel circuit, a display device, an electronic device and a driving method of the pixel circuit are provided to comprise a control unit preventing turn-on of an electronic optical device, thereby preventing a display unevenness phenomenon.;CONSTITUTION: A record transistor records a driving voltage in a storage capacity(120). A control input end of a driving transistor(121) is connected to one side in the storage capacity and a first node. The driving transistor drives an electronic optical device. A main electrode end in the driving transistor, the other side in the storage capacity, and one side in the electronic optical device are connected to a second node.;COPYRIGHT KIPO 2013;[Reference numerals] (104) Record injection unit; (106) Horizontal operating unit(horizontal selector, data operating unit); (625) Light emitting injection unit; (627) Threshold value voltage correction control injection unit; (AA) Power circuit
