  • Patent number: 7812832
    Abstract: A display is capable of displaying images in response to signals of a plurality of signal formats. The display includes a controller that is coupled to a plurality of image data interfaces. When the plurality of image data interfaces are simultaneously operating, the controller selects one of the plurality of image data interfaces according to preference variables associated with each of the plurality of image data interfaces. Each of the preference variables may indicate a relative priority of an image data signal format associated with the corresponding image data interface. In addition, each of the preference variables may indicate one or more performance metrics associated with the quality of image data signals received from the corresponding image data interface.

  • Patent number: 7009616
    Abstract: A display is capable of displaying images in response to differently formatted signals. The display includes a switch that enables a user to select among a plurality of signal formats. The switch has a first setting that corresponds to a first of the plurality of signal formats and a second setting that corresponds to a second of the plurality of signal formats. The display also includes a memory module that receives requests from a channel and transmits a response associated with the setting of said switch.

  • Patent number: 6359389
    Abstract: A flat panel display having a programmable gamma without incidental loss in gray scale resolution. In one embodiment, the flat panel display is a liquid crystal display (LCD). The invention includes applying and adjusting a set of gamma controlling voltages to the DC reference circuit (a.k.a. ladder voltages) of an LCD module producing a change in the gamma response (or profile) of the LCD module without incidental loss of gray scale resolution. An adjustable ladder circuit (ALC) is thereby realized. Separate ALCs can be provided for red, green and blue primaries. By adjusting, in a predetermined fashion, the reference voltages applied to the row and column drivers of an LCD display, the gamma response of the LCD can be changed to a different value. Because the input digital signals are not affected, the same color resolution and dynamic range are maintained. The DC reference circuit can be a multi-node voltage divider.
