摘要
A head mounted display (HMD) device is provided with reduced motion blur by reducing row duty cycle for an organic light emitting diode (LED) panel as a function of a detected movement of a user s head. Further a panel duty cycle of the panel is increased in concert with the decrease in the row duty cycle to maintain a constant brightness. The technique is applicable e.g. to scenarios in which an augmented reality image is displayed in a specific location in world coordinates. A sensor such as an accelerometer or gyroscope can be used to obtain an angular velocity of a user s head. The angular velocity indicates a number of pixels subtended in a frame period according to an angular resolution of the LED panel. The duty cycles can be set e.g. once per frame based on the angular velocity or the number of pixels subtended in a frame period.
