Benefits of technology

This invention relates to a display device that reduces heat and power consumption by using a fan-out line and low-voltage power supply line in the display area. By connecting the horizontal transmission lines to vertical transmission lines and data lines in the lower display area, a border reduction structure can be achieved. In the upper display area, the horizontal lines are connected to low-voltage power lines, allowing for a low-voltage power supply line structure. Combining these two techniques reduces the risk of heat generation and prevents an increase in power consumption. The design space of the power line unit is secured using the fan-out line technique.

Problems solved by technology

However, a CRT display apparatus is large and lacks portability.

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...
