Patent number: 12272321Abstract: Systems and methods for electronic displays to use reference voltages to control driving current of illuminators are provided. The reference voltages are used to reduce or eliminate cross talk in driving voltages among different illuminators and driving voltage variations from frame to frame. The transient performance of the driving current of the illuminator (e.g., the current rise/decline time, current overshoot issue, current settling time) may be improved by implementing the reference voltages.Type: GrantFiled: September 6, 2023Date of Patent: April 8, 2025Assignee: Apple Inc.Inventors: Ming Sun, Nicola Rasera, Robert D Zucker, Johan L Piper, Denis M Darmon, Fabio Ongaro, Xiaofeng Wang

Patent number: 12273102Abstract: This application discloses a system for turning off power consumption of an auxiliary startup circuit. An oscillator generates a switch control signal based on a reference current output by a circuit to be started up to generate a working clock of a switch control signal generation circuit after the circuit to be started up works normally. After fixed clock signal counting, the switch control signal generation circuit outputs a switch control signal to control power consumption of normally open current of the auxiliary startup circuit to be turned off. At the same time, the switch control signal generation circuit stops counting the clock. This application can assist the circuit to be started up having a “degeneracy” bias point to power on normally, and can also turn off the power consumption of the auxiliary startup circuit after the circuit to be started up is powered on.Type: GrantFiled: September 15, 2023Date of Patent: April 8, 2025Assignee: Shanghai Huali Microelectronics CorporationInventors: Xiaofeng Su, Yifei Qian, Zhili Wang
