  • Patent number: 10762834
    Abstract: Brightness irregularities that develop in a light emitting device due to is persion among pixels in the threshold values of TFTs used for supplying electric current to light emitting devices become obstacles to improved image quality of the light emitting device. As an image signal input to a pixel from a source signal line, a desired electric potential is applied to a gate electrode of a TFT for supplying electric current to an EL device, through a TFT having its gate and drain connected to each other. A voltage equal to the TFT threshold value is produced between the source and the drain of the TFT 105. An electric potential in which the image signal is offset by the amount of the threshold value is therefore applied to the gate electrode of the TFT. Further, TFTs are disposed in close proximity to each other within the pixel, so that dispersions in the TFT characteristics do not easily develop.

  • Patent number: 10755615
    Abstract: An intelligent, self-learning display uses knowledgebase rules to determine how to deform its flexible, touch-sensitive upper surface into a three-dimensional representation of displayed content. The upper surface is deformed by selectively inflating balloons, pistons, or other devices embedded into a lower layer of the display, such that the inflated devices exert upward pressure on specific regions of the surface. The flexible upper surface consists of two sublayers that each contain a grid of small strips. The two grids are skewed such that the lower-sublayer strips fill in otherwise-visible gaps between upper-sublayer strips during a deformation. A user may use tactile feedback to adjust characteristics of the deformation, such as the deformation's height. A machine-learning mechanism records user adjustments in a corpus that is then used to train the display to more accurately deform its surface when representing three-dimensional content.
