Using Liquid Crystals (epo) Patents (Class 348/E3.015)
  • Patent number: 11741913
    Abstract: An electronic display includes a plurality of pixels, each pixel including a data line, first and second selection lines and a common electrode. A control circuit element includes first and second diode-like elements coupled between the first and second selection lines and a charging node. A charging capacitive element is coupled between the charging node and the date line. An active pixel element is coupled between the charging node and the common electrode. The common electrode can overly the entire electronic display and is a suitable transparent conductive material. Each of the first and second diode-like elements includes an amorphous metal non-linear resistor. The active pixel element may include one of liquid crystal display circuitry, light emitting diode circuitry, and electrophoretic circuitry.

  • Patent number: 11521579
    Abstract: An electronic device may be provided with a display. The display may be formed from liquid crystal display pixels, organic light-emitting diode pixels, or other pixels. The display may have an active area that is bordered along at least one edge by an inactive area. The active area contains pixels and displays images. The inactive area does not contain any pixels and does not display images. The inactive area may have a layer of black ink or other masking material to block internal components from view. The active area may have an opening that contains an isolated portion of the inactive area or may contain a recess into which a portion of the inactive area protrudes. An electrical component such as a speaker, camera, light-emitting diode, light sensor, or other electrical device may be mounted in the inactive area in the recess or opening of the active area.

  • Patent number: 11475815
    Abstract: The present disclosure provides a driving method, a driving circuit, and a display device. The driving method includes steps of receiving a data signal of a first standard, generating a first data frame, and driving a display panel at a refresh frequency of the first data frame; and receiving the data signal of the second standard, calculating and generating at least one transition frame according to the data signal of the first standard and a data signal of a second standard, and driving the display panel at a refresh frequency corresponding to the at least one transition frame. A length of one frame time of the at least one transition frame is between a length of one frame time of the first data frame and a length of one frame time of the second data frame.

  • Patent number: 10373590
    Abstract: An automotive vehicle includes a cabin, a controller, and a multi-view display. The multi-view display has a first side facing the cabin and a second side facing the exterior of the vehicle. The multi-view display has a first-side display screen, a second-side display screen, and a blocking layer disposed between the first-side display screen and the second-side display screen. The first-side display screen and the second-side display screen are in communication with the controller and operable to display a first pattern on the first-side display screen and a second pattern, distinct from the first pattern, on the second-side display screen.
