Abstract

Display driving method and device capable of selecting driving pulse types. The display device includes a plurality of pixels, each of the plurality of pixels including a luminous element and a pixel circuit connected to the luminous element; and a data driver configured to provide image data and luminance data of the pixels to the pixel circuit, wherein the image data comprises multi-bit values including a Most Significant Bit (MSB) and a Least Significant Bit (LSB); and a processor configured to generate a Pulse Width Modulation (PWM) signal based on the multi-bit values when the luminance data is greater than a threshold value, and control light-emission and non-emission of the luminous element through the PWM signal, and drive the LSB using an impulse signal when the luminance data is less than the threshold value.
