Problems solved by technology

[0005] In addition, in the soldering process, the alignment mark of the printed circuit board and the alignment mark of the adjacent digitizer are photographed, and based on their distance, the solder (Solder) is sprayed (Jet) to the printed circuit board. Edge (Edge): Since the distance between the edges of the alignment mark of the printed circuit board is different due to the deviation of the cutting process of the printed circuit board, the position of the solder moves as a whole, which may cause short circuit defects and uneven solder formation

Abstract

The invention provides a printed circuit board and a display device including the same. The display device includes a wiring pattern portion including a wiring pattern and a wiring pad connected to the wiring pattern; a printed circuit board electrically connected to the wiring pattern portion; and a conductive substance for electrically connecting the wiring pattern portion and the printed circuit board, and the printed circuit board includes a base substrate; a plurality of circuit pads disposed on the base substrate and electrically connected to the wiring pattern through the conductive material; and a dummy pad provided between the adjacent circuit pads. A wiring pad includes a first portion overlapping the circuit pads and a second portion not overlapping the circuit pads, and the conductive material is provided at the second portion and is in contact with side surfaces of the circuit pads.

Description

technical field [0001] The present application relates to a printed circuit board and a display device including the printed circuit board. Background technique [0002] Organic light-emitting display devices have excellent luminance, driving voltage, and response speed characteristics, and are capable of multi-coloring, and thus are used in various products centering on smartphones. An organic light emitting display device includes a display panel including organic light emitting elements. An organic light-emitting element is provided with a cathode electrode and an anode electrode centered on an organic light-emitting layer, and when a voltage is applied to these two electrodes, visible light is generated from the organic light-emitting layer connected to the two electrodes. [0003] A panel lower sheet is attached to the lower part of the display panel. The panel undersheet may include various functional sheets for protecting the display panel from heat generation, exte...
