Problems solved by technology

The display device can provide more various functions through such an optical sensor, but when the optical sensor is disposed in the non-active area, there is a limit in reducing the area occupied by the non-active area in the display panel
[0007] Therefore, a method of disposing optical sensors and the like required in the display device in some areas of the active area of ​​the display panel has been tried, but there is a problem that the area where an image is displayed is limited due to the arrangement of the optical sensor or the quality of the image is degraded.

Abstract

Embodiments of the disclosure are related to a display device comprisng a display panel comprising a first area having a first resolution and a second area having a second resolution, mutiple first thin film transistors arranged in each of the plurality of sub-pixels located in the first area; and a plurality of second thin film transistors are provided in each of the plurality of sub-pixels located in the second area, wherein each of the plurality of first thin film transistors may include a gate located on one surface of the channel area of the first thin film transistor, each of the plurality of second thin film transistors may include a plurality of gates located on both surfaces of the channel area of the second thin film transistor. The present invention can realize the sensing function of the optical sensor located in the active area, and can compensate the brightness of the low-resolution area and prevent the brightness deviation between the low-resolution area and the high-resolution area.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Korean Patent Application No. 10-2019-0169598 filed on December 18, 2019, which is hereby incorporated by reference for all purposes as if fully set forth herein. technical field [0003] Embodiments of the present invention relate to a display device.
