US Patent Issued to GOOGLE on Oct. 7 for "Variable refresh rate control using PWM-aligned frame periods" (California Inventors)

ALEXANDRIA, Va., Oct. 8 -- United States Patent no. 12,437,727, issued on Oct. 7, was assigned to GOOGLE LLC (Mountain View, Calif.).

"Variable refresh rate control using PWM-aligned frame periods" was invented by Sang Young Youn (Cupertino, Calif.), Sun-il Chang (San Jose, Calif.), Wonjae Choi (San Jose, Calif.) and Sangmoo Choi (Palo Alto, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "PWM-frame rate misalignment is mitigated through implementation of a discrete variable refresh rate (VRR) scheme. A target frame rate is limited to a frame rate selected from only those frame rates that facilitate alignment of each frame period to a specified edge of a PWM cycle of a brightness control signal of a dis...
