    Abstract: In various examples, latency of human interface devices (HIDs) may be accounted for in determining an end-to-end latency of a system. For example, when an input is received at an HID, an amount of time for the input to reach a connected device may be computed by the HID and included in a data packet transmitted by the HID device to the connected device. The addition of the peripheral latency to the end-to-end latency determination may provide a more comprehensive latency result for the system and, where the peripheral latency of an HID is determined to have a non-negligible contribution to the end-to-end latency, a new HID component may be implemented, a configuration setting associated with the HID component may be updated, and/or other actions may be taken to reduce the contribution of the peripheral latency to the overall latency of the system.

    Abstract: A system and method are provided for display of a 3D image on a video monitor. A characteristic of each of a plurality of sample LCD panels is measured and a display parameter is calculated based on the measured characteristics. A first 3D image is displayed on one of the sample LCD panels using the calculated display parameter and the displayed image is evaluated. Based on the evaluation, each of the sample LCD panels is assigned to one of a plurality of groups. For each group, a group display parameter is calculated based on the measured characteristics of the panels assigned to the group. A video monitor controller is configured to display a second 3D image on an installation LCD panel. The second 3D image is displayed based on the group display parameters and an indication of a group to which the installation LCD panel is assigned.

    IPC: G09G3/3208 ,  G09G3/20

    Abstract: Certain display types—such as organic light emitting diode (OLED) displays—may be more prone to burn-in or ghosting due to the varied luminance degradation rates of pixel cells of the display—especially in applications or content types that require display of prolonged, continuous, static textures. To account for this, aging of pixel cells (e.g., R, G, B, and/or W pixel cells) of a display may be tracked such that more aged pixel cells may be compensated for by reducing pixel values of one or more (e.g., each) other pixel cells of the display. As a result, the effect of burn-in or ghosting may be mitigated by tracking luminance degradation over time and compensating for the luminance degradation across some or all of the pixel cells of the display.

    Abstract: A display device includes an array of LEDs, an array of LCD pixels, and a display controller. The display controller is configured to compensate for one or more sources of color variation in light produced by the LEDs. The display controller can determine a first color variation at a given LCD pixel based on the distance between the given LCD pixel and one or more LEDs. The display controller can also determine a second color variation at the given LCD pixel based on a current level supplied to the one or more LEDs. The display controller configures the given LCD pixel to filter light that is received from the one or more LEDs in a manner that reduces or eliminates either or both of the first and second color variations.
