Abstract

A display device includes: a pixel array and a driving part for driving the pixel array, wherein the pixel array part includes first scanning lines and second scanning lines arranged in rows, and signal lines arranged in columns are provided on the first scanning line, the second scanning line The matrix pixels at the intersection of the two scanning lines and the signal lines provide power to each pixel's power line and ground line. The driving section includes a first scanner for sequentially line-scanning the pixel row by sequentially supplying the first control signal to each of the first scanning lines, sequentially supplying the second control signal to each of the second scanning lines together with the sequential line scanning A second scanner, and a signal selector that provides video signals to the signal line columns along with sequential line scanning.

Description

technical field [0001] The present invention relates to a display device for displaying images by driving light-emitting elements arranged by pixels with current. More specifically, the present invention relates to a so-called active matrix type display device in which the amount of current passing through a light emitting element such as an organic EL element is controlled by an insulated gate type field effect transistor provided in each pixel circuit. More specifically, the present invention relates to techniques for optimizing the dimensioning of transistors formed within each pixel circuit, and also relates to electronic equipment in which such a display device is incorporated. Background technique [0002] In an image display device such as a liquid crystal display, for example, many liquid crystal pixels are arranged in a matrix, and an image is displayed by controlling transmission intensity or reflection intensity with respect to incident light for each pixel accord...
