Embodiment Construction

[0051] Embodiments of the present disclosure will be described in detail with reference to the drawings. Description will be made in the following order.

[0052] 1. Embodiment (display device)

[0053] 2. Modify (display device)

[0054] 3. Application example (electronic unit)

[0055] [1. Example]

[0056] [Configuration]

[0057] figure 1 An example of a general configuration of a display device 1 according to an embodiment of the present disclosure is illustrated. The display device 1 includes a display panel 10 and a driving circuit 20 arranged around the display panel 10 .

[0058] (display panel 10)

[0059] The display panel 10 includes a plurality of display pixels 14 all two-dimensionally arranged on a display area 10A of the display panel 10 . The display panel 10 drives each display pixel 14 in an active matrix manner to display an image based on an externally input video signal 20A. Each display pixel 14 includes, for example, a pixel for red 13R, a pix...

Abstract

Provided is a pixel circuit capable of obtaining high luminance while suppressing power consumption. In addition, a display panel with the pixel circuit and a display device including the display panel are provided. Furthermore, an electronic unit comprising the display device is provided. The pixel circuit includes: a first transistor for driving a light emitting element; a plurality of holding capacitors connected in series between the gate and source of the first transistor; between a first signal line and the gate of the first transistor a second transistor provided between; and a third transistor provided between the second signal line and one of the nodes of the hold capacitor.

Description

technical field [0001] The present disclosure relates to pixel circuits included in pixels of a display panel. The present disclosure also relates to a display panel in which a plurality of pixels each including the above-described pixel circuit are arranged two-dimensionally, and a display device having the display panel. Furthermore, the present disclosure relates to an electronic unit including the above-mentioned display device. Background technique [0002] In recent years, in the field of display devices for displaying images, display devices using current-driven optical elements such as organic EL (electroluminescent) elements as light-emitting elements of pixels have been developed and commercialized. The luminance of light emission varies according to the value of the current flowing therethrough. Unlike liquid crystal elements and the like, organic EL elements are self-luminous elements. Therefore, since a light source (backlight) is not required, a display devi...
