Patent number: 8664739Abstract: In accordance with the invention, an improved image sensor includes an array of germanium photosensitive elements integrated with a silicon substrate and integrated with silicon readout circuits. The silicon transistors are formed first on a silicon substrate, using well known silicon wafer fabrication techniques.

Patent number: 7808008Abstract: A display device in which not only a variation in a current value due to a threshold voltage but also a variation in a current value due to mobility are prevented from influencing luminance with respect to all the levels of grayscale to be displayed. After applying an initial potential for correction to a gate and a drain of a driving transistor, the gate and the drain of the driving transistor is kept connected in a floating state, and a voltage is held in a capacitor before a voltage between the gate and a source of the driving transistor becomes equal to a threshold voltage. When a voltage obtained by subtracting the voltage held in the capacitor from a voltage of a video signal is applied to the gate and the source of the driving transistor, a current is supplied to a light-emitting element. A value of an initial voltage for correction differs in accordance with the voltage of the video signal.Type: GrantFiled: June 19, 2008Date of Patent: October 5, 2010Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventor: Hiroyuki Miyake
