Abstract: Front-of-screen performance of the electronic display may be highly sensitive to timing settings of emission and anode reset frequencies. Changes in the timing settings may result in diverging brightness and color performance on the electronic display, which may negatively impact user experience. In some cases, emission frequency of the self-emissive display pixels may be fixed at a value, such as 120 Hertz (Hz), 240 Hz, or 480 Hz. The anode reset frequency may be set at a divisor of the emission frequency. Some refresh rates may be divisors of the pixel emission frequency. However, other refresh rates may not be divisors of the pixel emission frequency. For such non-divisor refresh rates, different driving schemes may be used to compensate for a difference from the pixel emission frequency.
