Abstract
Embodiments relate to a display device with reduced scanning time by using a reference line separate from a data line to improve frame rate of the display device. A first pixel in a first row samples a reference voltage during a first period and samples a data voltage during a second period. A second pixel in a second row adjacent to the first row samples the reference voltage during a third period and samples the data voltage during a fourth period, where the third period overlaps with at least a portion of the second period. The reference voltage is provided by the reference line that is connected to a reference buffer, and the data voltage is provided by the data line connected to a source driver circuit.
