ALEXANDRIA, Va., Sept. 28 -- Sanyo Semiconductor, Japan, and Semiconductor Components Industries, Phoenix, have been assigned a patent (8,542,166) developed by Tsutomu Murata, Mizuho, Japan, and Takashi Ogawa, Gifu, Japan, for an "electroluminescence display apparatus with video signal rewriting."
The abstract of the patent published by the U.S. Patent and Trademark Office states: "In performing a display in accordance with a video signal, a display signal for inspection is supplied to a pixel within a predetermined inspected row to operate an EL element therein and to thereby detect a current that flows through the EL element. The current detection data is stored in a volatile primary memory. In accordance with data obtained in this manner, a variation correcting section sequentially corrects data signals to be supplied to the respective pixel. At the time of turning on power, the variation correcting section performs the correction using the current detection data saved in a secondary memory. With this arrangement, it is possible to execute display variation correction from immediately after turning on power, and it is also possible to execute real-time correction."
The patent application was filed on Dec. 19, 2007 (11/959,663). 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=8542166.PN.&OS=PN/8542166&RS=PN/8542166
