Mechanoluminescent display device

#This application is a National Stage of International Application No. PCT/KR2014/012089 filed Dec. 10, 2014, claiming priority based on Korean Patent Application No. 10-2014-0070171 filed Jun. 10, 2014, the contents of all of which are incorporated herein by reference in their entirety.

#The following description relates to a display device, and more particularly, to a display device emitting light in a mechanical method using wind and vibration.

#A phenomenon of emitting light in a mechanical method, that is, light generated by applying a strength to a material has been known as mechanoluminescence (a superordinate concept including triboluminescence, fractoluminescence, deformation-luminescence, etc.) for a long time, but a principle of emitting the light is uncertain even until now and also has been treated as only an academic interest.

#FIG. 1 is a diagram for describing optical characteristics of a stress luminescent device in various stretching-releasing speeds according to an embodiment of the present invention;

#FIG. 2 is a diagram for describing a stretching-releasing test for testing optical characteristics of a stress luminescent device according to an embodiment of the present invention;

#FIG. 3 is a diagram for describing sample fabrication of the wind-stress luminescent device according to an embodiment of the present invention;

#The above and other objects, features and advantages of the present invention will become more apparent with reference to exemplary embodiments which will be described hereinafter with reference to the accompanying drawings. However, the present invention is not limited to exemplary embodiments which will be described hereinafter, and can be implemented by various different types. Exemplary embodiments of the present invention are described below in sufficient detail to enable those of ordinary skill in the art to embody and practice the present invention. The present invention is defined by claims. Meanwhile, the terminology used herein to describe exemplary embodiments of the invention is not intended to limit the scope of the invention. The articles “a,” “an,” and “the” are singular in that they have a single referent, but the use of the singular form in the present document should not preclude the presence of more than one referent.

#Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, when allocating reference numerals to components of each drawing, the same reference numeral will be allocated to the same component even when being shown in different drawings. Further, in the following description with respect to the exemplary embodiments of the present invention, when it is determined that a detailed description of well-known technology related to the present invention can unnecessarily obscure a subject matter of the present invention, the description will be omitted.
