Abstract

A pixel and a display device including the same. The pixel includes: a pixel circuit configured to control the amount of current to be supplied to an organic light-emitting diode in response to a datasignal provided from a data line; and a light sensor circuit coupled between the data line and the pixel circuit and configured to control the amount of current to be supplied to the pixel circuit inresponse to incident light.

Description

[0001] This application claims priority and benefit from Korean Patent Application No. 10-2018-0114287, filed September 21, 2018, which is hereby incorporated by reference for all purposes as if fully set forth herein . technical field [0002] Exemplary embodiments of the present invention relate to a pixel and a display device including the same. Background technique [0003] The display device may include: a display panel configured to display an image; and a touch panel configured to recognize a touch when a user's hand or a stylus is placed on the touch panel. Touch recognition schemes of touch panels may be classified into various types such as a piezoresistive overlay type, a contact capacitance type, a surface acoustic wave (SAW) type, an infrared sensing type, and a piezoelectric type. [0004] Research is being conducted on an in-cell type display panel in which a touch sensor circuit is integrated with display pixels, and research is also being conducted on a tou...
