Abstract: A shading device is described for use with a display system. The shading device includes a first component, typically a rigid component, and a second component. The second component at least partially covers the first component. The second component is a solid continuous film which has a lower reflectivity than the first component. In a particular embodiment, the second component is more elastic or flexible than the first component and/or has a hardness smaller than the first component, and is furthermore adapted such that it can provide a sealing contact with a plurality of light sources. The latter allows using the shading device also as a sealing arrangement for sealing electronics and other components of the display system from the ambient of the display system.

Abstract: The method and apparatus uses pulse-width-modulation to drive display elements, such as light emitting diodes, within an active matrix display. At least one of the shift cycles is a sub-pulse-width-modulation cycle in which the display is disabled for a fraction of the shift cycle. This provides an increased number of possible display colors for the display elements. Additionally, the display can be disabled for some portion of the remaining shift cycles in order to provide a dimming of the display without losing color resolution.
