One frame is divided into three subfields SF1, SF2, and SF3 having periods corresponding to respective bits of 3-bit gradation data. In cycles T of the subfield SF1 having the shortest period in one frame, an L or H data signal is written seven times to respective pixels to make a display with 2<SP>3</SP>gradations. Consequently, a holding period wherein pixel voltages written to the respective pixels in one frame are held up to next writing becomes short and drops of the pixel voltages in the holding period become small.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Filed: 2003-04-25
Abstract: <P>PROBLEM TO BE SOLVED: To provide an adjustable capacitor used for an LC or RC matching network in a micro-circuit.  <P>SOLUTION: A set of individual capacitors having a bottom portion electrode in common for them are formed. The areas of the top portion electrodes of the individual capacitors are so selected as to have their integer ratio to each other. Thereby, they can be so combined as to produce arbitrary capacitance within the scope of a unit values. For example, when providing the four capacitors whose areas have such ratio to each other as 5:2:1:1, arbitrary capacitors whose capacitance fall in the scope ranging from 1 to 9 can be generated depending on how their top portion electrodes are connected with the common bottom portion electrode. Such connections are performed in a wire-bonding mode at the final wiring level for providing an factory adjustable capacitor. Alternatively, such connections can be performed in a site via a programmable apparatus in order to provide in the field programmable capacitors. The process for manufacturing the device is also explained.  <P>COPYRIGHT: (C)2004,JPO
