Display device and pen touch system

A touch display device comprising a display panel including a plurality of light emitting elements and a plurality of transistors and an infrared absorption pattern formed on an emission surface of the display panel, wherein electrodes included in the plurality of light emitting elements or electrodes included in the plurality of transistors are infrared reflective electrodes.

Touch display device

A touch display device is disclosed. The touch display device includes a display panel. The display panel includes a light emitting element and a transistor made of a plurality of metal electrodes. The touch display device includes an infrared blocking film disposed on an emission surface of the display panel. The touch display device includes an infrared reflective pattern disposed on an inner or outer surface of the infrared blocking film.

The present disclosure provides a display device including a substrate, an encapsulation layer over the substrate, a touch sensor layer on the encapsulation layer and including a plurality of touch sensors, and a transmittance control layer on or under the touch sensor layer.

Display device

Embodiments of the disclosure relate to a wavelength control film and a display device. A wavelength control layer for absorbing part of light of a specific wavelength band is disposed on an outer surface of a transparent substrate of the display device to enable a correction to the color temperature of white light, thus allowing for high-efficiency driving and a high color gamut upon implementing white light. Further, adjustment of the light absorption peak wavelength and transmittance of the light absorption material included in the wavelength control film enables wavelength control, with the characteristics of the light emitting element considered, and reduce external light reflectivity to thus provide the functions of a polarization plate.

Wavelength control film and display device

The present application presents a light emitting diode module comprising a substrate including a first insulating layer, a second insulating layer, and a metal layer between the first and the second insulating layers; a groove formed at the first insulating layer for exposing the metal layer; and a light emitting element disposed at the groove, and including an LED chip and body part surrounding the LED chip, wherein the LED chip contacts the metal layer for radiating heat.
