Problems solved by technology

However, in the case of a digital driving method, crosstalk may occur due to a voltage drop occurring in the driving voltage line
In particular, as the size of the display panel increases, the occurrence of crosstalk may increase due to the voltage drop of the driving voltage caused by the resistance of the driving voltage line

Embodiment Construction

[0043] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of various embodiments or implementations of the invention. As used herein, "embodiment" and "implementation" are interchangeable words that are non-limiting examples of apparatuses or methods that employ one or more of the inventive concepts disclosed herein. It is evident, however, that various embodiments may be practiced without these specific details, or with one or more equivalent arrangements. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring the various embodiments. Furthermore, various embodiments may be different, but not necessarily exclusive. For example, the specific shape, configuration and characteristics of an embodiment may be used or implemented in another embodiment without departing from the inventive concept.

Abstract

A display device includes: a plurality of pixels disposed in a display area; a plurality of first voltage lines electrically connected to the plurality of pixels, the plurality of first voltage lines including a plurality of first common voltage lines extending in a first direction and a plurality of second common voltage lines extending in a second direction intersecting the first direction; and a plurality of second voltage lines electrically connected to the plurality of pixels, the plurality of second voltage lines including a plurality of first driving voltage lines extending in the first direction and a plurality of second driving voltage lines extending in the second direction. The number of the first common voltage lines is greater than the number of the first driving voltage lines.

Description

technical field [0001] Embodiments of the present invention relate generally to a display device, and more particularly, to a display device having vertical voltage lines and horizontal voltage lines. Background technique [0002] An organic light-emitting display includes two electrodes and an organic emission layer interposed between the two electrodes. Electrons injected from one electrode and holes injected from the other electrode recombine in the organic emission layer to generate excitons, and the excitons pass through The energy of the excitons is converted to emit light. [0003] An organic light emitting display includes a plurality of pixels including an organic light emitting element as a self light emitting element. Each of the pixels includes a plurality of thin film transistors and one or more capacitors for driving organic light emitting elements. [0004] Due to the recent trend toward larger areas, display devices are manufactured with large-area display ...
