Title:
ORGANIC LIGHT-EMITTING DISPLAY DEVICE AND METHOD OF DRIVING THE SAME
Document Type and Number:
Japanese Patent JP2016105192
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an organic light-emitting display device which prevents sensing defects and offers better display quality by enhancing external compensation accuracy, and to provide a method of driving the same.SOLUTION: An organic light-emitting display device includes: a display panel (100) including a plurality of pixels, each comprising an organic light-emitting diode and a pixel circuit that drives the organic light-emitting diode; a gate driver (300) that supplies the plurality of pixels (P) with a scan signal, sensing signal for sensing, and drive voltage; a data driver (200) that supplies respective pixels with data voltages and a reference voltage in a driving mode, and senses voltages charged in the plurality of pixels in a sensing mode; a timing controller (400) that controls the gate driver (300) and the data driver (200) to have them operate in either of the driving mode and sensing mode; and a memory (500) that stores compensation data for compensating the plurality of pixels (P).SELECTED DRAWING: Figure 4
