Abstract

A display device includes a plurality of pixels on a substrate, each of the plurality of pixels including a pixel circuit to drive a plurality of light emitting elements, wherein the pixel circuit of each of the plurality of pixels includes: a first transistor configured to supply a driving current to a first electrode of the light emitting elements; and a plurality of light emitting groups, each of which includes some of the light emitting elements and a bypass unit connected between the first electrode and a second electrode of the some of the light emitting elements to selectively bypass a part of the driving current.

Description

technical field [0001] The present disclosure relates to display devices. Background technique [0002] With the advancement of an information-oriented society, more and more demands are being placed on display devices that display images in various ways. For example, display devices are used in various electronic devices such as smart phones, digital cameras, laptop computers, navigation devices, and smart TVs. The display device may be a flat panel display device such as a liquid crystal display device, a field emission display device, and an organic light emitting display device. In a light-emitting display device among flat panel display devices, since each of the pixels of the display panel includes a light-emitting element capable of emitting light by itself, an image can be displayed without a backlight unit for supplying light to the display panel . [0003] Each of the plurality of pixels of the display panel may include a plurality of light emitting elements. T...
