US 2022/0044629 A1 · High-Brightness Mode on an OLED Display

Abstract

This document describes techniques and apparatuses for a high-brightness mode on an organic light emitting diode (OLED) display. 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.

Dependent claims

A method for controlling screen brightness on an organic light emitting diode (OLED) display, the method comprising:

setting a first display brightness value within a display driver integrated circuit (DDIC) associated with the OLED display;
providing, in accordance with the first display brightness value, a first brightness on the OLED display by:
driving the OLED display at a first frequency, two or more pulses, and a first gamma correction set;
setting a second display brightness value within the DDIC associated with the OLED display, the second display brightness value greater than the first display brightness value;
and
providing, in accordance with the second display brightness value, a second brightness on the OLED display by:
adjusting, by at least one processor separate from with the DDIC, to fewer pulses;
and
driving the OLED display at the first frequency, the fewer pulses, and a second gamma correction set.
