Abstract

The present disclosure relates to an electroluminescent lighting device embedding touch function. The present disclosure provides an electroluminescent light device that includes a substrate includingan emission area and a non-emission area surrounding the emission area. An emission element is disposed on a first surface of the substrate in the emission area. A first pad and a second pad are disposed on the first surface of the substrate in the non-emission layer. A touch layer is disposed on a second surface of the substrate opposite the first surface, and a cover plate is attached on a bottom surface of the touch layer.

Description

technical field [0001] The present disclosure relates to electroluminescent lighting devices embedded with touch functionality. In particular, the present disclosure relates to an electroluminescent lighting device including an organic light emitting element and a touch layer on the same substrate. Background technique [0002] Recently, based on many advantages and / or strengths of organic light emitting devices, a series of studies have been actively conducted to use organic light emitting elements as light sources of lighting devices or display devices. For example, surface light sources and / or point light sources provided with organic light-emitting elements are applied to lighting systems of vehicles, such as interior ambient lights, headlights, fog lights, telescopic lights, car lights, digital lights, tail lights, brake lights, turn lights Wait. [0003] When an organic light emitting element is applied to a lighting device, it must have a strong structure against fo...
