CROSS-REFERENCE TO RELATED APPLICATION

Korean Patent Application No. 10-2018-0129206 filed on Oct. 26, 2018, in the Korean Intellectual Property Office, and entitled: “Display Device,” is incorporated by reference herein in its entirety.

BACKGROUND

1. Field

The present disclosure relates to a display device.

2. Description of the Related Art

A light emitting diode display has a self-luminance characteristic, i.e., does not require a separate light source, so a thickness and a weight of the display may be reduced. Further, the light emitting diode display has additional desirable characteristics, e.g., low power consumption, high luminance, high reaction speed, etc. In general, the light emitting diode display includes a substrate, a plurality of transistors on the substrate, and a light-emitting device connected to the transistors.

SUMMARY

An exemplary embodiment provides a display device including: a display panel including a first region and a second region; and a sensing module on a rear side of the display panel. The first region includes a first pixel area to display an image. The second region overlaps the sensing module. The second region includes a second pixel area to display an image and a transmission area to transmit light output by the sensing module. The second pixel area overlaps a first layer that blocks light output by the sensing module and the transmission area does not overlap the first layer.

The second pixel area may include a plurality of transistors, and the first layer may overlap all of the transistors.

The second pixel area may include a plurality of transistors, and the first layer may overlap some of the transistors.

The transmission area may be separated from the first layer in a plan view.

The first pixel area may be separated from the first layer in a plan view.

The first pixel area may overlap the first layer.

The first layer may overlap part of the first pixel area.

The first pixel area may include a plurality of transistors, and the first layer may overlap some of the transistors.

The second pixel area may include a plurality of transistors, and the first layer may overlap at least one of the transistors.

The first pixel area may not overlap the first layer.

The first pixel area may include the first layer overlapping some of a plurality of transistors, and the second pixel area may overlap more of the first layer than the first pixel area.

An area occupied by the transmission area may be 20% to 90% of the second region.

The display panel may include a first substrate on which a transistor is provided, and the first layer may be between the sensing module and the transistor.

Another embodiment provides a display device including: a display panel including a first region and a second region; and a sensing module on a rear side of the display panel. The second region overlaps the sensing module. The first region includes a first pixel area to display an image. The second region includes a second pixel area to display the image and a transmission area to transmit light output by the sensing module. Overlap percentages of first layers in the first pixel area and in the second pixel area are different with respect to a same area, the first layers to block light output by the sensing module.

The transmission area may not overlap the first layer.

The first pixel area may not overlap the first layer, and at least part of the second pixel area may overlap the first layer.

An entirety of the second pixel area may overlap the first layer.

Part of the first pixel area may overlap the first layer, and an entirety of the second pixel area may overlap the first layer.

The first layer overlapping the first pixel area may receive a predetermined voltage.
