Display device and method for driving the same

A method for driving a display device, wherein the display device includes:

• a display panel including at least one of a first sub-pixel, a second sub-pixel, a third sub-pixel and a fourth sub-pixel;
• a light-emission transistor connected to each of the first to fourth sub-pixels;
• a driving transistor connected to the light-emission transistor;
• and
• a driver configured to control a light-emission operation of the at least one of the first to fourth sub-pixels,
• wherein the method comprises:
• receiving a light-emitting control signal in response to application of an image signal from a timing controller;
• turning on the driving transistor;
• switching the driving transistor so that a data voltage set in a first control mode is applied to the at least one of the first to fourth sub-pixels;
• turning on the light-emission transistor;
• switching the light-emission transistor for a set pulse width in a second control mode;
• and
• emitting a light of the at least one of the first to fourth sub-pixels in the pulse width set in the second control mode by the data voltage set in the first control mode,
• wherein in the second control mode, the current value and the data voltage value of the at least one of the first to fourth sub-pixels are fixed respectively to a first specific value and a second specific value, and the pulse width is variable.
