  • Display device
    Patent number: 6806857
    Abstract: Grey scale linearity and power efficiency in active matrix (O) LEDs are enhanced by storing the grey value in a memory circuit, coupled to an adjusting circuit, preferably via a current mirror.
    Type: Grant
    Filed: May 1, 2001
    Date of Patent: October 19, 2004
    Assignee: Koninklijke Philips Electronics N.V.
    Inventors: Adrianus Sempel, Iain Mcintosh Hunter, Mark Thomas Johnson, Edward Willem Albert Young
  • Light switching device with reset
    Patent number: 6654154
    Abstract: A reset driving scheme for addressing a switching mirror display enables current to flow in two directions through the switching elements. The display is forced into a predefined state and drives the display into the other optical states by using an addressable TFT providing a continous current.
    Type: Grant

    Assignee: Koninklijke Philips Electronics N.V.
    Inventors: Mark Thomas Johnson, Iain Mcintosh Hunter, Steven Charles Deane
  • Display device
    Patent number: 6509690
    Abstract: Grey scale linearity and power efficiency in active matrix (O) LEDs are enhanced by operating the display in a switched mode.
    Type: Grant
    Filed: May 2, 2001
    Date of Patent: January 21, 2003
    Assignee: Koninklijke Philips Electronics N.V.
    Inventors: Adrianus Sempel, Iain Mcintosh Hunter, Mark Thomas Johnson, Edward Willem Albert Young
  • Light switching device with reset
    Publication number: 20020109900
    Abstract: A reset driving scheme for adressing a switching mirror display (20) enables current to flow in two directions through the switching elements (30). The display is forced into a predefined state and drives the display into the other optical states by using an adressable TFT (31) providing a continous current. A circuit that fulfils these requirements is indicated.
