Claim Text:
1. A device, comprising: a plurality of pixel circuits arranged in a matrix having columns and rows, the pixel circuits to supply light-emitting currents to light-emitting elements according to data voltages being written; a plurality of data lines including n data lines (n being an integer of 2 or more) extending along each column, wherein the n data lines include first and second data lines being respectively connected to first and second pixel circuits in a same column and selectively receiving the data voltages and an initial voltage; a plurality of gate lines to supply scan signals to the plurality of pixel circuits; and a plurality of light-emitting control lines to supply light-emitting control signals indicating whether to supply the light-emitting currents of the plurality of pixel circuits, and wherein each pixel circuit includes: a driving transistor to control an amount of a light-emitting current to be supplied to a light-emitting element in response to a data voltage; a write control transistor to control whether gate and drain electrodes of the driving transistor are electrically connected in response to a scan signal; a light-emitting control transistor between the driving transistor and the light-emitting element, the light-emitting control transistor to control whether to supply the light-emitting current to the light-emitting element in response to a light-emitting control signal; a capacitive element between a data line and the gate electrode of the driving transistor, the capacitive element to retain the data voltage; and a reset transistor to set the gate electrode of the driving transistor with the initial voltage before storing the data voltage to the capacitive element, and wherein when a light-emitting element of the first pixel circuit in the same column emits light, the second pixel circuit in the same column receives the data voltage through the second data line and the first pixel circuit receives the initial voltage through the first data line, and when a light-emitting element of the second pixel circuit in the same column emits light, the first pixel circuit in the same column receives the data voltage through the first data line and the second pixel circuit receives the initial voltage through the second data line.
