Systems, devices, and methods for using clock detector circuitry to reduce turn-on time of an electronic display, improve image quality, and reduce operations of a host are provided. In one example, a system may include a host configured to transmit a number of signals and a display driver coupled to the host. The number of signals may include a clock signal and data signals. The display driver is configured to drive a display based at least in part on the data signals. The display driver is also configured to be reset upon detection of the clock signal without waiting for a host-issued reset signal. A clock detect circuit configured to detect the clock signal may be configured to transmit an internal reset signal to reset the display driver without a dedicated host-issued reset signal.

Using clock detect circuitry to reduce panel turn-on time

A system and method for characterizing the power and luminance values for a display. This may include testing a device to determine a luminance value for a display of a given device at a given current and determining whether the first current is to be adjusted during future uses based on a comparison of the luminance with at least one threshold value. This may also include storing an adjusted current value if it is determined that the first current is to be adjusted.
