Display systems are incorporated in, or used by, a plurality of devices, including televisions, computer monitors, laptop computers, personal digital assistants (PDAs), mobile phones and watches. Often, there is a need for these devices to incorporate a more or less static component into the image or images that they project. The static image component may take various forms, including those of: a company logo, a battery status indicator, a signal strength indicator, a recording indicator, or an alarm indicator. Static image components may also take the form of text and/or graphic images. To display such an indicator, a new set of control signals must typically be generated for the display system. Sometimes, this can require a great deal of overhead.
