Abstract: In conventional liquid crystal display controllers such as for portable telephone sets, the display is reduced in the stand-by state but the liquid crystal display duty is not changed, i.e., even the common electrodes of the rows that are not producing display are scanned, and the consumption of electric power is not decreased to a sufficient degree in the stand-by state.

Abstract: Pixel clock frequency and optimum sampling phase adjustment is an important requirement in Flat panel display monitors (FPDM) with an analog video interface. This invention proposes a new and more advanced method for frequency and optimum sampling phase determination. It is based on analyzing the content of the image to arrive at an optimum value of phase and frequency by directly optimizing image quality. The method differs from existing methods on two counts. First, no assumptions are needed about the precise value of expected frequency. Second, instead of following a two step approach of first determining frequency and then phase, this invention makes possible a single pass phase-frequency optimization.

Abstract: In a graphics pipeline, a rasterizer circuit generates fragments for an image having multiple surfaces that have been tessellated into primitive objects, such as triangles. First and second fragments are associated with the same pixel.

A frame buffer receives fragments from the merge buffer, stores the fragments, combines the fragments into pixels, and outputs the pixels to a display.

Abstract: Elements of a graphical user interface that are switchably translucent and opaque are disclosed. In one embodiment, such an element is initially set to a default, first mode in which the element is translucent when the pointer is not positioned over the element.

Abstract: Network management can be made more efficient by using a graphical user interface that is clear and concise in what network information is identified and subsequently displayed. One key to improving graphical user interfaces is the categorizing of network entities into a series of attribute layers that define different features of the network entities. For instance, a layer of attributes may include geographical regions, services, customers, or types of network entities. By selecting a base view from the group of geographical regions and then network features for filtering operations from one or more of the other attribute layers, the network entities defined by the selected network features can be identified and isolated with all other irrelevant network entities being filtered out. The advantages to this graphical user interface is especially evident when considering the case that a specific customer, service, or network entity requires special attention.
