AI Technical Summary
Technical Problem
In active matrix organic electroluminescent displays, data transmission loss caused by capacitors affects data transmission rate and power consumption of the display device.
Method used
A pixel circuit design is adopted, including driving elements, multiple switching elements and capacitors. The switching elements are turned on and off by a specific scanning signal, which optimizes the storage and transmission process of data voltage and avoids the loss of data voltage distribution by the capacitor.
Benefits of technology
It improves data transmission rate, reduces power consumption of display device, and enables accurate sensing of threshold voltage, thereby improving brightness uniformity.

Abstract
Embodiments disclose a pixel circuit and a display device including the same. The pixel circuit includes: a driving element including a first electrode to which a pixel driving voltage is applied, a gate connected to a first node, and a second electrode connected to a second node; a first switching element turned on in response to a first scan signal to connect a data voltage line and a third node; the second switching element is turned on in response to a second scanning signal so as to connect the third node and the first node; a third switching element which is turned on in response to a second scanning signal so as to connect the reference voltage line and the fourth node; the fourth switching element is turned on in response to a second scanning signal so as to connect the fourth node and the first node; a first capacitor connected between the third node and the fourth node; and a second capacitor connected between the fourth node and the second node.
