Patent number: 6756962Abstract: A liquid crystal image display comprising differential amplifiers composed of polycrystalline Si TFTs incorporated in buffer for a signal line driver. The image display includes buffer outputting switches for turning off the outputs of the buffers and signal line shunting switches for shorting the input and output terminals of the buffer. For the first half of one horizontal period, the signal line shunting switches are held off whereas the buffer outputting switches are held on, to feed signal lines with an image signal voltage selected by level select switches through the buffers.Type: GrantFiled: June 7, 2002Date of Patent: June 29, 2004Assignee: Hitachi, Ltd.Inventors: Hajime Akimoto, Yoshirou Mikami

Publication number: 20040061671Abstract: A display apparatus is arranged in a manner that each pixel includes a light emitting element for emitting light in response to a current flowing therein, a first switching element for fetching luminance information into a pixel from a signal line, and a second switching element for controlling a current amount to be supplied to the light emitting element in accordance with the luminance information thus fetched; the luminance information is fetched by fetching the signal voltage of the signal line when a scanning line connected to the pixel is selected; and the luminance information thus fetched in each of the pixels is kept in a capacitor even after the scanning line connected to the pixel is place in a non-selection state.Type: ApplicationFiled: August 14, 2003Publication date: April 1, 2004Applicant: Hitachi Displays, Ltd.Inventors: Masahiro Kawasaki, Yoshirou Mikami, Hajime Murakami, Masahiko Andou, Kenichi Onisawa, Akitoyo Konno
