Abstract:
A display apparatus includes a plurality of pixels. A pixel includes a first capacitor connected between a first voltage line receiving a first driving signal and a first node, a first transistor comprising a control electrode connected to the first node, a first electrode connected to a second voltage line receiving a first power source signal and a second electrode connected to a second node, an organic light emitting diode comprising an anode electrode connected to the second node and a cathode electrode receiving a second power source signal, a second capacitor connected between an m-th data line and the second node (wherein, ‘m’ is a natural number) and a second transistor comprising a control electrode connected to an n-th scan line (wherein, ‘n’ is a natural number), a first electrode connected to the first node and a second electrode connected to the second node.
