Abstract: Systems and methods for emoji prediction and visual sentiment analysis are provided. An example system includes a computer-implemented method. The method may be used to predict emoji or analyze sentiment for an input image. An example method includes the step of receiving an image. The example method further includes the steps of generating an emoji embedding for the image and generating a sentiment label for the image using the emoji embedding. The emoji embedding may be generated using a machine learning model.

Abstract: A display may store extended display identification data for communicating the capabilities of the display to a source device such as a graphics processing unit. The extended display identification data may include a red primary color value, a green primary color value, and a blue primary color value. The primary color values in the extended display identification data may be determined during manufacturing. For example, a light sensor may measure the native primary colors of the display, and calibration computing equipment may determine if the native primary colors of the display are within a target color gamut. If the native primary colors of the display are outside of the target color gamut by an amount larger than a threshold, the primary color values in the extended display identification data may be adjusted to account for the color variation.

Abstract: The embodiments discussed herein relate to systems, methods, and apparatus for synchronizing a pulse width modulation (PWM) dimming clock signal with a frame rate signal, line sync signal, and/or a horizontal sync signal of a display device. The PWM dimming clock signal can be generated by a synchronization block having a programmable offset/delay. The programmable offset/delay can control the offset or phase difference between an input and an output clock signal of the synchronization block. Depending on the clock rate of PWM dimming and/or panel resolution, the phase/offset delay can be adjusted to achieve the optimum front of screen performance. Additionally, an input clock generator/missing pulse detection block can output a programmed clock signal to the synchronization block in case of a missing external clock, or insert a pulse when there is a missing pulse detected.

Abstract: A method and system for modifying a pulse width modulation signal for controlling the backlit illumination intensity of a liquid crystal display. The modified pulse width modulated signal may be selected to operate with at least one pulse having a first duty cycle with the remaining pulses in the pulse width modulation signal having a second duty cycle across a selected number of pulses making up a given time period (i.e., frame). By utilizing more than one duty cycle for the pulses of the pulse width modulated signal to drive light sources in a display during a given frame, the overall number of backlit illumination intensities for the liquid crystal display may be increased. By distributing the differing pulse duty cycles within a group of pulses of within a frame, visible artifacts may be reduced.

Abstract: Display driver circuitry loads data into display pixels. A regulator produces a power supply voltage for display driver circuitry that is measured by a monitor circuit. The monitor circuit asserts a mode selection signal in response to detection of a drop in power supply voltage during a power-down event. The display driver circuitry contains mode selection circuitry that is controlled by the mode selection signal. The mode selection circuit allows a controlled parallel driver shutdown sequence. During normal operation, the mode selection signal is deasserted and the display driver circuitry loads image data for the display into the display pixels. When the mode selection signal is asserted, mode selection circuitry and other circuitry in the display driver circuitry continue to operate during the power down so as to load safe data into the display pixels to avoid damaging the display when the display has been powered off.

Abstract: Disclosed embodiments relate to techniques for enhancing luminance resolution in a backlight unit. A backlight unit may have light-emitting diode (LED) light sources arranged in strings. In one embodiment, a backlight controller provides enhanced luminance resolution by drive each LED string at either first or second consecutive luminance values corresponding to first and second duty cycles of a pulse width modulation (PWM) signal. The outputs of the LED strings are optically mixed to achieve intermediate luminance values between the first and second luminance values.
