Display device

Abstract

A display device includes a data line, a vertical transmission line and a horizontal transmission line. The data line extends in a first direction and is arranged in a second direction on a display area divided into upper and lower display areas, and is connected to pixels. A vertical transmission line extends in the first direction on the display area. The vertical transmission line receives a ground power supply voltage from an upper side of the display area to transfer the ground power supply voltage to the pixels, and receives a data voltage from a lower side of the display area. A horizontal transmission line extends in the second direction on the display area and is arranged in the first direction. The horizontal transmission line is connected to the vertical transmission line and the data line on the lower display area to transfer the data voltage to the data line.

Description

[0001]This application claims priority to Korean Patent Application No. 10-2020-0166121, filed on Dec. 1, 2020, and all the benefits accruing therefrom under 35 U.S.C. § 119, the content of which in its entirety is herein incorporated by reference.BACKGROUND1. Field[0002]Embodiments of the invention relate to a display device. More particularly, embodiments of the invention relate to a display device configured to reduce the risk of heat generation and to reduce power consumption.2. Description of the Related Art[0003]Recently, a lightweight and small display apparatus has been manufactured. A cathode ray tube (“CRT”) display apparatus has been used in the past due to its performance and competitive price. However, a CRT display apparatus is large and lacks portability. Therefore, flat display apparatuses such as a plasma display apparatus, a liquid crystal display apparatus or an organic light-emitting display apparatus have been widely used due to various desired characteristics s...

Benefits of technology

[0023]According to embodiments of a display device, as disclosed herein, in a lower display area, both ends of the horizontal transmission lines are connected to a vertical transmission line and a data line, respectively, so that a border reduction structure (“BRS”) in which fan-out lines are in the display area may be realized. In such embodiments, in the upper display area, the horizontal transmission lines may be connected to the vertical transmission lines that deliver low-voltage power, so that a low-voltage power supply line structure in the display area (ELVSS On Active or “EOA”) may be realized. In such embodiments, infrared rays that may be generated in the display device may be reduced by combining the BRS, which is a technology for reducing a dead area at a lower end of the display device, and the EOA, a technology for forming a low-voltage power line formed in a display area. In such an embodiment, based on the BRS, a design space of the power line unit may be secured, such that a risk of heat generation is substantially reduced and an increase in power consumption is effectively prevented.
