    Abstract: A capacitive sensing device includes a switch circuitry, a counter circuit, a comparator circuit, an amplifier circuit including first and second input terminals and an output terminal, and a feedback capacitor coupled between the output terminal and the first input terminal. The switch circuitry transmits a reference voltage to the second input terminal and couples the first input terminal to the output terminal during a first phase, transmits another reference voltage to the second input terminal during a second phase, and adjusts a voltage of the output terminal during a third phase. The counter circuit starts counting and the comparator circuit generates the control signal according to the output voltage and the second reference voltage during the third phase. The counter circuit stops counting according to the control signal to generate a count value indicating a capacitance value change of a capacitor under-test coupled to the first input terminal.

  • Patent number: 11967290
    Abstract: An electronic display device has a panel that operates in conjunction with a light-emitting diode (LED) backlight. The device “slopes” or gradually ramps a change in brightness of an LED based on a target brightness value of the LED, a current brightness value of the LED, and temperature at the LED. The device also may limit power to the backlight based on an estimated power consumption of a current row of LEDs of the backlight and power consumption of the other rows of LEDs. The device also may determine a reduced voltage to supply to an LED based on a current to supply to the LED to cause the LED to operate. The device also may send an interrupt to the backlight to block updates to the backlight while image content is written to pixels of the panel. The device further compensates for aging of and temperature at an LED.
