  • Publication number: 20220157264
    Abstract: A local-dimming display generally includes a light source configured to generate a backlight, a first display aligned with the light source and having multiple first pixels, wherein each first pixel is configured to selectively pass and block the backlight, and a second display aligned with the first display and having multiple second pixels. A particular pixel is controlled to pass the backlight. The particular pixel corresponds with an aligned pixel and multiple parallax pixels of the first pixels controlled at a first transmit level, and multiple neighboring pixels of the first pixels controlled at one or more second transmit levels. The one or more second transmit levels are less than or equal to the first transmit level. The first pixels cooperating at the first transmit level and the second transmit levels selectively presents the backlight to the second display with a declining intensity pattern in the neighboring pixels.

  • Publication number: 20220155638
    Abstract: A high dynamic range display includes a light source, a first display and a second display. The light source is configured to generate a backlight. The first display is aligned with the light source and has multiple first pixels. Each first pixel is configured to selectively pass and block the backlight. The second display is aligned with the first display and has multiple second pixels. A particular pixel is controlled to pass the backlight at a first transmit level. The particular pixel corresponds with an aligned pixel of the first pixels controlled to pass the backlight at a second transmit level and a multiple parallax pixels controlled to pass the backlight.
