Abstract
A display device includes a display panel and an infrared sensing module. The display panel includes an active region in which a pixel that emits light based on a data signal is disposed. The infrared sensing module transmits a first infrared light that passes through the active region and receives a second infrared light that passes through the active region to recognize an object. The wavelength of the first infrared light may have a wavelength greater than a predetermined value so that a luminance of light emitted by the pixel is not affected by operation of the infrared sensing module.
Claims20
A display device comprising:
- a display panel having a front surface and a rear surface, the display panel including an active region in which a pixel that emits light based on a data signal is disposed, and the active region including a first region and a second region that is different from the first region;
- and
- an infrared sensing module that transmits a first infrared light that passes in a first direction away from the front surface of the display panel and through the first region of the active region, and that receives a second infrared light that passes in a second direction toward the front surface of the display panel and through the first region of the active region by which the infrared sensing module recognizes an object external to the display device,
- wherein a first pixel density of the first region of the active region is lower than a second pixel density of the second region of the active region.
