ALEXANDRIA, Va., Sept. 21 -- Synaptics, San Jose, Calif., has been assigned a patent (8,537,099) developed by Ovidiu Aioanei, San Jose, Calif., for a "dynamic voltage supply for LCD timing controller."
The abstract of the patent published by the U.S. Patent and Trademark Office states: "An integrated circuit voltage supply circuitry for liquid crystal display and a method are disclosed. The voltage supply comprises a DC voltage regulator having a reference voltage input and a feedback voltage input; a positive voltage pin and a negative voltage pin providing power to the DC voltage regulator; a network of resistors comprising a plurality of parallel branches, each branch having at least one resistor and one node; a plurality of LCD modules supported by the DC voltage regulator, each module connecting to the node of each parallel branch; a plurality of diodes each formed between the node of one module and a feedback diode; and the feedback diode connected to the feedback voltage input of the DC voltage regulator, wherein the DC voltage regulator keeps the voltage for each LCD module not lower than the reference voltage, regardless of each module's consumption of current."
The patent application was filed on Sept. 8, 2010 (12/877,246). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=8537099.PN.&OS=PN/8537099&RS=PN/8537099
