A display device may include: a display panel including a display area in which a plurality of pixels are disposed, and a non-display area disposed around the display area; and a gate driver configured to receive a start signal and a clock signal and to supply a gate signal to the display panel. Each of the plurality of pixels may include at least one first transistor and at least one second transistor having characteristics different from characteristics of the at least one first transistor. The gate driver may include at least one third transistor and at least one fourth transistor having characteristics different from characteristics of the at least one third transistor.

Display device having pixel circuits and gate driver with different transistor characteristics

An organic light emitting display device and a method for providing low luminance power thereof includes a data driver including a lookup table storing therein a low potential voltage and an initialization voltage corresponding to each gamma set such that a low potential voltage and an initialization voltage in a 60 Hz operation mode are respectively different from a low potential voltage and an initialization voltage in a 90 Hz operation mode and a method compensates for an anode charging time in the low luminance range, thereby improving seamlessness.
