  • Patent number: 10997946
    Abstract: Methods and systems relating generally to information displays, and more particularly to systems and methods for setting or dynamically adjusting the illumination pulses of a display or portions of a display on an individual color channel (typically R, G, B) basis. The illumination pulses may be adjusted for a plurality of frames at once, or on a frame by frame basis. The illumination pulses may be controlled for an entire image frame, or the illumination pulse may be controlled on a finer basis, for instance on separate areas or sub-regions of a display. Such adjustments can lead to improved sharpness, brightness, or useable lifetime of the display, and can eliminate or reduce discrepancies of visual artifacts in the visual field by providing separate or variable duty cycle capability on an individual color channel basis to the display for use in combination with display images, particularly for use with close-eye display orientations such as those used in augmented reality or virtual reality applications.

  • Patent number: 10957872
    Abstract: An electrode and an organic electroluminescent device using the same are provided. The electrode comprises a first conductive layer (1), a second conductive layer (2) and a third conductive layer (3) that are arranged in a stacked manner The second conductive layer (2) has a single-layer structure or multi-layer composite structure formed by at least one of alkali earth metal, alkali earth metal alloy and alkali earth metal compound, and the third layer (3) has a work function of less than 3 eV. The respective conductive layers of the electrode can compensate with respect to the defects in one another, thereby making the performance of the electrode more stable. In the meantime, because the work function of the third conductive layer (3) is less than 3 eV, the barrier of organics-metal interface can be effectively reduced for guiding the electron injection, thereby increasing the light-emitting efficiency of device.
