Abstract: A single panel display may have discrete, dedicated segments associated with each of the primary colors. The segments may not be equally sized in some embodiments. The light from a light source may be split into color portions that are adjusted to accommodate to the differently sized segments dedicated to different colors.

Abstract: A display may be implemented with a pulse width modulated system in which the number of pulse width modulated slots may be divided up across the frame using less than the full number of available pulse width modulated slots per color. In addition, within any given field time, the pixels may be operated on in slots spread relatively evenly across the entire field time in some embodiments. In one embodiment, a spatial light modulator directly controls the pixel values at a pulse width modulated slot.

Abstract: Embodiments of the invention provide a driver device for delivery of pixel values in a digitally encoded (PWM) fashion to a LCOS imager, such as a 2-megal pixel imager. In particular, modulated pixel values may be delivered to a LCOS imager. Driver device functions as a high definition imager driver and transmits a PWM pixel stream through interface to imager. Pixel input stream may be received by low I/O buffer which may be implemented as a voltage differential signaling (LVDS) I/O buffer. The data may then be processed at input block, and restored into frame buffer banks. Through pixel lookup tables, the frame data gets transformed into a PWM pulse train and shifted off driver device onto an imager. Frame buffer to signal generator interface may include multiplexers for reordering bits before signal generation.

Abstract: A method and apparatus for performing transparent data transfer operations on graphics data (such as video data), in which a source image currently displayed as part of a destination image (or stored in memory) is moved to a selected destination location on the destination image without obliterating background portions of the destination image. In a class of embodiments, the invention accomplishes a transparent bit-block transfer by clocking out source data (stored in an internal memory) to a bank of arithmetic logic units (ALUs), and processing the source data in the ALUs to identify portions of the source data representing transparent (or background) data which should not replace corresponding destination data, and which represent foreground data (new text to replace destination data). The marked source data are selectively written into a video memory containing the destination data, to selectively overwrite only those destination data pixels corresponding to new text.

Abstract: The present invention provides a contrast enhancing method and circuit for mapping color signals into signals for driving a display which is capable of displaying shades of gray. With the present invention a preliminary translation is first made between a foreground-background color combination and the various shades of gray that can be displayed. The contrast or separation between the foreground level of gray and the background level of gray produced by this preliminary translation is then compared to parameters set by the operator.

Abstract: A display processor for displaying data in one or more windows on a display screen. The display processor divides a display screen into a plurality of horizontal strips with each strip further subdivided into a plurality of tiles. Each tile represents a portion of a window to be displayed on the screen. Each tile is defined by tile descriptors which include memory address locations of data to be display in that tile. The descriptors need only be changed when the arrangement of the windows on the screen is changed or when the mapping of any of the windows into the bit-map is changed. The display processor of the present invention does not require a bit map frame buffer to be utilized before displaying windowed data on a screen. Each horizontal strip may be as thin as 1 pixel, which allows for the formation of windows of irregular shapes, such as circles.
