  • Patent number: 9997584
    Abstract: A load, a transistor which controls a current value supplied to the load, a capacitor, a power supply line, and first to third switches are provided. After a threshold voltage of the transistor is held by the capacitor, a potential in accordance with a video signal is inputted and a voltage that is the sum of the threshold voltage and the potential is held. Accordingly, variation in current value caused by variation in threshold voltage of the transistor can be suppressed. Therefore, a desired current can be supplied to a load such as a light emitting element. In addition, a display device with a high duty ratio can be provided by changing a potential of the power supply line.

  • Patent number: 9977514
    Abstract: The invention provides a digital painting apparatus and method that captures the natural textures in physical painting tools. It is comprised of a plurality of sensors below a painting surface and a light source arranged such that reflective objects near the sensors are imaged, with the nearer parts of the objects forming brighter parts of those images. The images are thresholded to include only the parts of those objects nearest the painting surface and accumulated in a display buffer to leave painted strokes that preserve those textures as the objects are moved. A display is located below the painting surface, substantially coincident with the sensors, and feedback from the display is substantially removed from the sensor images before they are thresholded, providing more uniform sensitivity.
