Embodiment Construction

[0046] Embodiments of the present invention have been described in detail with reference to the accompanying drawings. FIG. 1 is a schematic block diagram of an overall configuration of an instruction display device according to an embodiment of the present invention. As shown in the figure, the image display device basically includes a pixel array section 1, and a driving section including a scanner section and a signal section. The pixel array section 1 includes: scanning lines WS, AZ1, AZ2, and DS arranged in rows; signal lines SL arranged in columns; and a pixel circuit 2 connected to these scanning lines WS, AZ1, AZ2, and DS and the signal lines SL , and they are arranged in rows and columns; and a plurality of power supply lines, which provide the first potential Vss1 , the second potential Vss2 and the third potential Vcc necessary for the operation of each pixel circuit 2 . The signal section includes a horizontal selector 3, and supplies a video signal to a signal li...

Abstract

A display apparatus, comprising a pixel array section and a drive section that drives the pixel array section, wherein the pixel array section includes first scanning lines and second scanning lines arranged in rows, signals lines arranged in columns, pixels that are provided where the first scanning lines, the second scanning lines, and the signal lines meet and that are arranged in rows and columns, a power line that supplies power to each of the pixels, and an earth line. The drive section includes a first scanner that sequentially line scans the pixels in rows by sequentially supplying a first control signal to each of the first scanning lines, a second scanner that sequentially supplies a second control signal to each of the second scanning lines in conjunction with the sequential line scanning, and a signal selector that supplies a video signal to the columns of signal lines in conjunction with the sequential line scanning.

Description

technical field [0001] The present invention relates to a display device and its driving method. The display device displays images by driving each light-emitting element arranged in pixels by 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, etc.) Insulated Gate Field Effect Transistor control is provided. Background technique [0002] In an image display device (such as a liquid crystal display), for example, a large number of liquid crystal pixels are arranged in a matrix, and an image is displayed by controlling the transmission intensity or reflection intensity of each pixel for incident light according to the image information of the image to be displayed. The same principle applies to an organic EL display that uses organic EL elements for its pixels, but unlike liquid crystal pixels, the organic EL elements ...
