Abstract: The method of the present invention produces a plurality of bi-level waveforms on the ROW/common lines and COLUMN/segment lines of a passive multiplexed liquid crystal display (LCD). These waveforms drive the LCD display using binary data from display memory locations. At periodic intervals a counter is incremented while the counter value is then used to 1) look-up in a table the bi-level data to output on the ROW/commons; 2) look-up memory locations associated with the active COLUMN/segments; and 3) to provide inverted COLUMN/segments data before sending the bi-level data to the COLUMN/segment lines of the LCD. The counter increments from zero to four times the number of ROW/commons before being reset to zero and the waveforms repeated. Thus, an algorithm produces one ON/select voltage and one OFF/non-select voltage that are provided to the LCD.

Abstract: A shielding enclosure (10) shields an electronic circuit (12) from radio frequency interference (RFI) or electromagnetic interferences (EMI). The shielding enclosure is an electrically conductive polyhedron having at least one aperture (18). The enclosure has a closable member (20), which is a part of the polyhedron, arranged to enable the aperture to be opened and closed. The polyhedron can be an electrically conductive metal enclosure that covers the shielded circuit, and is mechanically and electrically attached to the circuit. The aperture has an integral flap (21) connected to the enclosure at one end (23), so that it is able to be opened and closed to reveal the shielded circuit. Any openings remaining in the polyhedron when the aperture is closed are less than or equal to 1/4 wavelength of the interfering radio frequency energy.
