  • Publication number: 20230073431
    Abstract: High resolution displays, such as OLED displays, utilize complex driving circuits that can suffer from crosstalk. The crosstalk can affect the brightness of pixels in a row the display, which can be observed by a viewer as a crosstalk artifact. The severity of a crosstalk artifact may correspond to a contrast ratio of a high-contrast transition in which vertically adjacent pixels are sequentially driven by different driving signals during a scan. When a contrast ratio is above a maximum-perceptible contrast ratio, reducing the contrast ratio to the maximum-perceptible contrast ratio and can reduce, or eliminate, crosstalk artifacts. Disclosed herein are methods and devices that adjust pixels to reduce a crosstalk artifact without having a noticeable effect on contrast.

  • Patent number: 9858872
    Abstract: An electronic is provided. An input unit provides a multimedia content. An image processor transforms the multimedia content into frame data. A display unit displays images including blue pixels, green pixels, and red pixels. A backlight unit generates a source light. A source light includes a deep blue-light of a low blue waveband and a far blue-light of a high blue waveband. A display panel transforms the source light into the images based on the frame data and emits the images through a surface. An optical path travels through the backlight unit and the surface. A deep blue-light filter is arranged in the optical path through which the source light passes, for restricting a light transmission rate in the low blue waveband. The image processor adjusts a color hue of the frame data to be transformed by the display panel.

  • Patent number: 8933915
    Abstract: A display apparatus, an integrated circuit and method thereof are disclosed. The display apparatus includes a frame buffer, a controller circuit, and a display driver circuit. The frame buffer is configured to retain a plurality of image frames to be displayed. The controller circuit, coupled to the frame buffer, is configured to determine whether a change in the image frames has occurred and whether a refresh time is expired. The display driver circuit, operatively coupled to the frame buffer and adapted to couple to an active display device, is configured to receive the image frames to be displayed from the frame buffer and dynamically refreshing the active display device when the change is determined or when a refresh time is expired.
