The techniques and apparatuses set a high-brightness value in a register of a display driver integrated circuit (DDIC) associated with the OLED display of on electronic device. A processor of the electronic device provides a fewer-pulses command to the DDIC, which adjusts a pulse number to control the OLED display at fewer pulses per period. A gamma correction is determined based on the high-brightness value and used to alter content to be presented on the OLED display. As a result, fewer pulses are used in combination with the gamma correction to provide content on the OLED display at a high brightness.
