  • Patent number: 10366663
    Abstract: A display device can use clock dithering to spread the frequency spectrum of the clock signal (and the signals derived therefrom) to mitigate interference with other components or systems in a host device. However, dithering the clock signal can introduce display artifacts into the display device. For example, lines or rows in the display may flicker, the brightness of display lines may be non-uniform, or color shifts in displayed pixels. To reduce display artifacts, the embodiments herein synchronize clock dithering to a display update event. That is, the display device varies a parameter of clock dithering so that the dithering is synchronized to the display update event. In another embodiment, the clock dithering is set according to the rate at which display lines or sub-pixels are updated. In another embodiment, clock dithering is synchronized to a display frame update period.

  • Patent number: 10331240
    Abstract: The invention discloses a device and a method to control an object on a surface using motion sensor measurements and relative and absolute pointing algorithms. Relative pointing is preferred at low speeds and absolute pointing is preferred at high speeds. Transition between the results of the two algorithms has to be smoothed, using a weighted combination of the two results. The weights may be made dependent over time or over speed of the device. Maximum and minimum values of different parameters may have to be set to avoid jumps or changes in direction which may affect the user's experience negatively. The goal is that the user has consistent perceptions what he or she sees on the screen and the movements he or she imparts on the device, while still keeping the position of the object as close as possible to the position calculated by an absolute pointing algorithm.

  • Patent number: 10311791
    Abstract: The purpose of the present invention is to suppress the fluctuation of a data line voltage that occurs when an analog voltage signal is sampled and held in a data line in a display device provided with a current-driven display element. Transistors (SWr, SWG, SWb) of each demultiplexer (252) are successively switched on, for each predetermined period, in a selection period of a write control line (SW_LR(i)). In a period when the transistor (SWr) is switched on, an analog video signal (Dj) from a data voltage output unit circuit (211d) is applied to a data line (SLrj) and a pixel circuit (50r). When the transistor SWr is then switched off, the voltage held by the data line (SLrj) decreases below the voltage of the analog video signal (Dj) due to a parasitic capacitance (Cssdr). However, the voltage of a voltage fluctuation compensation line (G3_Cnt (i)) changes from a low level to a high level within the selection period.

  • Patent number: 10277943
    Abstract: Peripheral visualizations are based on user movements and/or interactions with elements in a scene. Various user movements are detected while a scene is being rendered. Afterwards, the embodiments determine whether one of the movements corresponds with an increase in a level of focus by the user to the one or more elements and/or an interaction by the user with the one or more elements. Thereafter, peripheral visualizations are rendered on one or more peripheral displays proximate elements that correspond with the user movements/interactions/focus. In some instances, the selective rendering is performed in response to a determination that the user movement does correspond with the increase in the level of focus by the user to the one or more elements and/or the interaction by the user with the one or more elements.
