Abstract
Provided are an organic light-emitting diode (OLED) display and method of driving the same. An OLED display includes: a display panel including a plurality of pixels, each pixel including an OLED, an emission timing of each pixel being controlled in response to an EM signal, a shift register configured to generate an anti-phase EM signal based on gate shift clocks, and an inverter configured to: invert a phase of the anti-phase EM signal based on emission shift clocks, and generate the EM signal, wherein a driving frequency of the shift register and a driving frequency of the inverter are lower in a low-speed driving mode than in a normal driving mode, and wherein in the low-speed driving mode, an amplitude of the emission shift clocks is less than an amplitude of the gate shift clocks.
