Abstract: A method for operating an electronic display includes displaying image frames and receiving operational parameters of the electronic display based on illuminating a sense pixel of at least one row of pixels of the electronic display when displaying the image frames. A first set of pixels below the at least one row of pixels renders a portion of a first image frame and a second set of pixels above the at least one row of pixels renders a portion of a second image frame. The method also includes adjusting image display of a third image frame on the electronic display based on the operational parameters.

Abstract: A mobile electronic device includes a display having a pixel and processing circuitry separate from but communicatively coupled to the display. The processing circuitry prepares image data to send to the pixel and adjusts the image data to compensate for operational variations of the display based on feedback received from the display that describes a present operational behavior of the pixel. The mobile electronic device also includes additional electronic components that affect the present operational behavior of the pixel depending on present operational behavior of the additional electronic components.

Abstract: Systems, methods, and devices are provided to reduce noise present in sensing circuits used for calibrating light emitting diodes (e.g., organic light emitting diodes) in electronic display devices. Such a system may include a display that renders image data using self-emissive pixels. Values on the pixels may be sensed using a current source that outputs a current and a comparator that receives the current. The comparator changes states when a voltage signal output by the capacitor crosses a first threshold voltage or a second threshold voltage. A controller receives a first time when the comparator component changes states based on the voltage signal, receives a second time when the comparator component changes states based on the voltage signal, determines a current value based on the first time and the second time, and calibrates a pixel based on the current value.

Abstract: An electronic device includes a display panel with pixels arranged in at least one row and at least one column. The electronic device also includes a sensing channel coupled to the at least one column. The sensing channel indirectly calculates a threshold voltage of the plurality of pixels based on an application of a first current level and a second current level to a data line of a first column of the at least one column of the pixels.

Abstract: An electronic device includes a display and a controller. The controller is configured to receive one or more operational characteristics of the display. The controller is also configured to calculate a blank time voltage level for a data line of the display based on the one or more operational characteristics, wherein the blank time voltage level corresponds to a voltage transmitted along the data line of the display immediately subsequent to image data being transmitted along the data line.

Abstract: This application sets forth a circuit configuration for a light emitting diode (LED) or organic light emitting diode (OLED) display. The circuit configuration allows for the pulse-width modulation (PWM) of each emission signal sent to each line of the display. The PWM of each emission signal is accomplished using a gate-in-panel (GIP) controller of the display. The GIP controller uses an arrangement of shift register outputs and a programmable clock input to control an output of an inverter that provides the emission signal. The programmable clock input can be programmed according to a desired timing or duty cycle for the emission signal. In this way, by limiting the duty cycle of the emission signal, dimming and other display features can be exhibited by the LED or OLED display.

Abstract: Systems, methods, and devices to control a transistor to maintain one or more substantially constant characteristics while activated or deactivated are provided. One such system includes a transistor that receives an activation signal on a gate terminal to become activated during a first period and receives a deactivation signal on the gate terminal to become deactivated during a second period. The transistor receives an input signal on an input terminal during the first period and the second period. The input signal varies during the first period and during the second period. The transistor may have improved reliability (e.g., substantially constant on resistance RON) because a first difference between the input signal and the activation signal substantially does not vary during the first period and a second difference between the input signal and the deactivation signal substantially does not vary during the second period.
