SYSTEMS FOR AND METHODS OF AMBIENT-LIGHT REDUCTION IN OLED DISPLAY SYSTEMS AND LCD SYSTEMS

摘要

Systems and methods for ambient-light reduction in display systems with OLED or LCD based displays are disclosed. The base display is interfaced with an ambient-light-reducing (ALR) structure to form the display system. The ALR structure includes an ALR component. The ALR component can be a photochromic component or a fixed neutral-density component. The ALR structure attenuates incoming ambient light as well as outgoing redirected ambient light that is generated within the base display and is then emitted from the display system into the ambient environment. This increases the ambient contrast relative to that of the base display alone.

主权项

1. A display system that displays a display image in either a low-light or a bright-light ambient environment, the display system comprising:
a base display configured to generate the display image, the base display including at least one of an organic light-emitting diode (OLED) display or a liquid crystal display (LCD), the base display having an upper surface and structures that form redirected ambient light from ambient light incident thereon; an ambient-light-reducing (ALR) structure interfaced with the upper surface of the base display and having an upper surface, and a photochromic component, and an antireflection coating, wherein the ambient light travels through the photochromic component toward the base display and interacts with the structures to form the redirected ambient light, which travels through the photochromic component and out of the upper surface of the ALR structure; the photochromic component having a transparent mode in the low-light ambient environment wherein the photochromic component does not substantially attenuate either the ambient light or the redirected ambient light that passes therethrough; and the photochromic component having a darkened mode in the bright-light ambient environment wherein the photochromic component substantially attenuates the ambient light and the redirected ambient light that passes therethrough.
