  • MITIGATION OF LIGHT EMITTING DIODE (LED) DISPLAY DRIVER INPUT PEAK POWER IN AUGMENTED REALITY (AR) / VIRTUAL REALITY (VR) DEVICES
    Publication number: 20250203731
    Abstract: A power management system for a display light emitting diode (LED) driver for an augmented reality/virtual reality (AR/VR) device mitigates (e.g., attenuates) an input peak power delivered to the LED driver from a DC source and decreases a voltage ramp rate of the LED driver while maintaining the default current ramp rate or vice versa. A liquid crystal on silicon (LCOS) digital process is used to provide a current reference with a slow ramp rate and/or to provide an offset. The offset (e.g., a delay) may be implemented between the voltage ramp and the current ramp to achieve a non-overlapping output voltage and output current.
