  • LCD in which the transparent electrode of a pixel is coated with a conducting material to modify its electrode work function to prevent flicker
    Patent number: 7006183
    Abstract: In a display device comprising a first substrate having at least one transparent, first picture electrode of a first material, a second substrate comprising at least one second picture electrode of a second material which, jointly with the picture electrode on the first substrate and an intermediate opto-electronic material, defines a pixel, and means for supplying electric voltages to the picture electrodes, the work function between the two picture electrodes is decreased in that at least one of the picture electrodes is coated with at least one layer of conducting material, or a layer of a material comprising a dipole.
    Type: Grant
    Filed: February 6, 2001

  • Display device in which one of the two electrodes of a pixel is coated with a dipole material to equalize the electrode work functions
    Patent number: 6236440
    Abstract: In a display device comprising a first substrate having at least one transparent, first picture electrode of a first material, a second substrate comprising at least one second picture electrode of a second material which, jointly with the picture electrode on the first substrate and an intermediate opto-electronic material, defines a pixel, and means for supplying electric voltages to the picture electrodes, the work function between the two picture electrodes is decreased in that at least one of the picture electrodes is coated with at least one layer of conducting material, or a layer of a material comprising a dipole.
