摘要： Systems and methods for inaudible enhanced pulse width modulation (PWM) backlight dimming are provided. By way of example, an electronic display backlight system according to the present disclosure may include a backlight element and backlight driver circuitry. The backlight driver circuitry may drive the backlight element at various brightness levels using at least two individual duty cycles that occur immediately after one another. The backlight driver circuitry may vary the individual duty cycles such that none will ever reach 100% unless all are 100%, thereby preventing the occurrence of audible noise that might otherwise arise if an “on” PWM period from one individual duty cycle continued into the next.

摘要： Systems, devices, and methods for using a hot plug detect (HPD) signal to reduce turn on time of a backlight of a display are disclosed. The backlight controller may pre-charge the backlight based at least in part on receiving the HPD signal prior to receiving a BL_EN signal to turn on the backlight. The HPD signal may be a multipurpose signal used by components of a system in addition to the backlight driver. The backlight driver may turn on the pre-charged backlight immediately upon receiving the BL_EN signal. The backlight controller may maintain the pre-charge of the backlight while the device is in a sleep state to reduce the turn on time of the backlight from the sleep state. Embodiments of the HPD signal may also power down the display and backlight.

摘要： The disclosed embodiments provide an apparatus that controls a current drawn from an adapter by a computer system. During operation, the apparatus senses the current drawn from the adapter using a first current sensor and a second current sensor, wherein a response time of the first current sensor is faster than a response time of the second current sensor. Then, when the current sensed using the first current sensor exceeds a predetermined high-current threshold, the apparatus limits the current drawn from the adapter to a first predetermined current limit. Additionally, when the current sensed using the second current sensor exceeds a predetermined thermal-limit current, the apparatus limits the current drawn from the adapter to the predetermined thermal-limit current.
