Publication number: 20070120993Abstract: In realizing an entire-screen simultaneous shutter function using a solid-state imaging device having a device structure as a CMOS solid-state imaging device, the restriction undergone by exposure time is relieved to secure a sufficient exposure time with swift operation. Separately from a transfer Tr for transferring a signal charge of a buried-type PD to an FD, a drain Tr is provided to exclude a signal charge of the buried PD. Both a channel potential on the drain transistor when turned on and a channel potential on the transfer transistor when turned on are set higher than a depleting potential for the PD. This makes it possible to completely transfer the signal charge of the PD by both the transfer Tr and the drain Tr. In the operation to sequentially read out a signal charge from the FD on a pixel-row basis, PD exposure operation is started in a course of reading out the same.Type: ApplicationFiled: January 17, 2007Publication date: May 31, 2007Inventor: Keiji Mabuchi

Publication number: 20070121033Abstract: The invention provides a display device of which a contrast ratio is enhanced. By providing stacked polarizing plates so as to be in a cross nicol state, a contrast ratio of a display device can be enhanced. The stacked polarizing plates are stacked outside a light-transmissive insulating substrate in a parallel nicol state. When the number of polarizing plates is four or five in total, a contrast ratio becomes the highest.Type: ApplicationFiled: October 27, 2006Publication date: May 31, 2007Applicant: SEMICONDUCTOR ENERGY LABORATORY CO., LTD.Inventors: Tetsuji ISHITANI, Yuji EGI, Takeshi NISHI, Koji MORIYA

Publication number: 20070121039Abstract: In order to make a boundary inconspicuous, which is located between an image area which displays an image by translucent pixels and a dummy area which always displays a white color by reflection pixels, a size ratio of transparent areas in color filters of the reflection pixels with respect to reflection areas therein is made larger than a size ratio of transparent areas in color filters of the translucent pixels with respect to reflection areas therein. In such a way, brightness of the display is balanced by adjusting quantities of transmission light through the transparent areas of the reflection pixels with respect to quantities of reflection light generated unexpectedly on transmission areas of the translucent pixels. Then, degrees of whiteness in the translucent pixels and the reflection pixels are approximated to each other.Type: ApplicationFiled: November 2, 2006Publication date: May 31, 2007Applicant: Toshiba Matsushita Display Technology Co.,Ltd.Inventors: Keiji Tago, Hiroshi Tabatake, Hiroyuki Kimura, Tetsuya Iizuka
