Assignee:

Flextronics AP, LLC - Broomfield CO

International Classification:

H04M 1/00

US Classification:

4555621, 455101, 4555501, 343893

Abstract:

Generally, an antenna module includes a plurality of monopole antenna elements (e. g. , 3 to 4 antenna elements) that can be coupled together by one or more switches to provide for a tunable, wideband antenna module. For example, the switches may change the overall length of the antenna such that the frequency range of the antenna is changed. The frequency response may also be controlled by a low voltage micro sized varicap, or a varactor diode, and instantiated as a tuned, resonant matching filter network residing with the antenna module. Additionally, switches may be used to “switch in” and “switch out” capacitive elements to adjust the bandwidth of the antenna. The resonant matching filter network may then be used for fine tuning the frequency of that bandwidth.

International Classification:

G09G 300

US Classification:

345 89

Abstract:

The video memory and the half-frame buffer frame accelerator of a dual scan LCD display are integral in a single memory device. Flat-panel read and write cycles to the frame accelerator designed area inside the memory are optimized in order to minimize memory bandwidth requirements. Extra memory space in the memory device may be used to buffer multiple half-frames of shaded data in such a manner as to save a considerable amount of power in the LCD display graphics system.
