摘要: An apparatus for detecting a change in a voltage level of a power supply is disclosed. An inverter coupled to a first power supply may generate a signal dependent upon a voltage level of a second power supply. A latch coupled to the first power supply may be set based on a first voltage level of the second power supply and a first value of the signal, and re-set based on a second voltage level of the second power supply and a second value of the signal different than the first value of the signal.

摘要: A display may have an active area that includes display pixels. The display may include an inactive notch region that extends into the active area. Data lines may provide image data from display driver circuitry to the display pixels. The image data may include data signals that correspond to portions of the display that do not include pixels, such as the inactive notch region. The null data signals may cause nonuniformities in the displayed image. The null data signals may be adjusted to minimize the nonuniformities. Null data signals corresponding to the inactive notch region may be adjusted to have gray levels that gradually decrease with distance from the border between the inactive notch and the active area. All of the data signals corresponding to the inactive notch may be set to a uniform gray level.

摘要: An apparatus includes a master latch circuit including a first circuit and a second circuit, and a slave latch circuit including a third circuit and a fourth circuit. The first circuit and the second circuit may be coupled to a first shared circuit node, and the third circuit and the fourth circuit may be coupled to a second shared circuit node. The master latch circuit may be configured to store a value of an input signal in response to an assertion of a clock signal. The slave latch circuit may be configured to store an output value of the master latch circuit in response to a de-assertion of the clock signal. The master latch circuit may also be configured to de-couple the first shared circuit node from a ground reference node in response to the de-assertion of the clock signal.

摘要: In an embodiment, an apparatus includes an input circuit coupled to a first power supply with a first voltage level, a power circuit coupled to a second power supply with a second voltage level, and an output driver. The input circuit may receive an input signal, and generate an inverted signal dependent upon the input signal. The power circuit may generate a power signal in response to first values of the input and the inverted signals, wherein a voltage level of the power signal may be dependent upon the second voltage level. The power circuit may also generate a third voltage level on the power signal in response to second values of the input and the inverted signals. The output driver may generate an output signal dependent upon the input signal. The output signal may transition between the voltage level of the power signal and the ground reference level.

摘要: An electronic device display may have an active area with pixels. An optical sensor may be formed under a sensor region in the active area. During operation, ambient light and/or other light associated with the optical sensor may pass through the sensor region. To ensure that the light for the optical sensor can pass through the display, the display may have one or more layers with sensor openings such as a metal layer and a pressure sensitive adhesive layer that attaches the metal layer to the pixels of the display. To help minimize visibility of the openings in the sensor region, the pressure sensitive adhesive layer may be configured to have a reflectivity that matches the appearance of the display in the sensor region to surrounding areas. Undesired light output uniformity can be reduced by ensuring that the substrate material in the display has a low light absorption coefficient.
