Abstract:
A video display device including a display screen (30, 40) having a first aspect ratio displays a video image (32, 47) having a second aspect ratio, together with framing images (34/36, 48/49, 54/56, 68/69), either above and below or at both sides of the video image (32, 47). The pattern and/or color of the framing images (34/36, 48/49, 54/56, 68/69) may be pre-selected to match a color of a cabinet housing the display screen (30, 40), or selected by a user based on whatever the user finds to be least distracting. Alternatively, a selection circuit may select a pattern and/or color for the framing image (34/36, 48/49, 54/56, 68/69) based on color content of the video image (32,47). Moreover, the program material containing the video image (32, 47) may include a code/codes that identifies a pattern and/or color to be used for the framing images (34/36, 48/49, 54/56, 68/69).
Abstract:
The present invention involves a semiconductor device, such as a shift register, wherein information in the form of charge carriers is moved laterally through the bulk of a semiconductor layer by means of an electric field, while the charge carriers are stored at the surface of the semiconductor layer. According to this invention, information containing regions can be separated from each other by depletion zones extending through the thickness and the width of the semiconductor layer. Charge transport laterally through the interior of the semiconductor layer results in a considerable reduction of the transport time. Majority charge carriers are advantageously used.
