ALEXANDRIA, Va., Sept. 17 -- United States Patent no. 12,416,838, issued on Sept. 16, was assigned to Semiconductor Energy Laboratory Co. Ltd. (Atsugi, Japan).
"Display device" was invented by Hajime Kimura (Atsugi, Japan) and Atsushi Umezaki (Isehara, Japan).
According to the abstract* released by the U.S. Patent & Trademark Office: "An object is to provide a display device that performs accurate display. A circuit is formed using a transistor that includes an oxide semiconductor and has a low off-state current. A precharge circuit or an inspection circuit is formed in addition to a pixel circuit. The off-state current is low because the oxide semiconductor is used. Thus, it is not likely that a signal or voltage is leaked in the prechar...
