Title:
An organic emitting display device and its drive method
Document Type and Number:
Japanese Patent JP6037391
Kind Code:
B2
Abstract:
An organic light emitting display device includes a display panel (100) including a plurality of pixels (P) having an organic light emitting diode (OLED) and a pixel circuit (PC); a gate driver (300) to supply the plurality of pixels (P) with a scan signal (scan), a sensing signal (sense), and a driving voltage; a data driver (200) to supply data voltages to the data lines (DL) and a reference voltage (Vpre_r) to the sensing lines (RL) in a driving mode, to supply a reference voltage (Vpre_s) to the sensing lines (RL) during parts of the sensing mode, and sense voltages charged into the plurality of pixels (P) in a sensing mode; a discharging driving unit (250) to initialize voltages of a plurality of sensing power lines (RL) when the display device switches from the driving mode to the sensing mode; a timing controller (400) to control the gate driver (300), the data driver (200), and the discharging driving unit (250) to operate in and switch between the driving mode and the sensing mode; and a memory (500) to store compensation data for the plurality of pixels (P).
