Organic light emitting diode

A planar lighting mirror in which nano-patterns are formed on an entirety or at a specific local area of a mirror surface of a mirror glass and a light source is disposed around the nano-patterns to be used like a mirror in normal operation. In particular, when the light source is activated, the entirety or the specific local area of the mirror surface with the nano-patterns formed thereon planarly emits light from the light source which flows into the side of the mirror glass so as not to deteriorate a mirrors reflective functions.

Disclosed are a synthetic resin composition for use as building materials such as window frames, as well as a product manufactured using the same. More particularly, the synthetic resin composition comprises a tetrapolymer of acrylic rubber-styrene monomer-butadiene rubber-vinyl cyanide monomer and a styrene-vinyl cyanide copolymer having a high molecular weight and a high degree of dispersion. Unlike products manufactured using prior polyvinyl chloride (PVC), building material such as window frames manufactured using the synthetic resin composition are recyclable, and thus can contribute to a reduction in the generation of hormone-disrupting chemical dioxin, which is released in the burning thereof. Also, the resin composition can be manufactured into products having excellent properties of weather resistance and colorability without using environmental pollutants such as cadmium stearate or lead stearate, which are used as thermal stabilizers.
