Abstract:
PURPOSE: A polymer is provided to have high triplet energy level, thereby providing an organic light emitting diode with high current density and high luminance. CONSTITUTION: A polymer includes m repeating units. The n^th repeating unit of the repeating units is a first repeating unit indicated in chemical formula 1. A first dihedral angle between the A_1 ring of the n^th repeating unit and the first aromatic ring of an n-1^th repeating unit and/or a second dihedral angle between the A_2 ring of the n^th repeating unit and the second aromatic ring of the n+1^th repeating unit have an angle of χ_50%=A+B(Φ+4Θ) or more.

PURPOSE: A polymer is provided to transfer all holes and electrons, to have a high triplet energy level, thereby being capable of improving performance of current density, brightness, etc. of an organic light emitting diode. CONSTITUTION: A polymer comprises repeating units in chemical formula 1 and has a weight average molecular weight of 2000-100000. An organic light emitting diode comprises a substrate, a first electrode, a second electrode, a first layer which comprises the polymer and is inserted between the first electrode and the second electrode. The first layer is an electroluminescent layer and comprises a phosphorescent dopant. The phosphorescent dopant is a metal complex comprising metal selected from of the following: Ir, Pt, Os, Re, Ti, Zr, Hf, or combinations thereof.

PURPOSE: By including an emitter including emitter composition for formation, emitter, and pointed materials the field emission capability can rise. Pointed materials the manufacturing method and field emission device expose to the cracked portion. CONSTITUTION: A cracked portion(14) is at least formed in the partial domain. A pointed material(15) exposes within the cracked portion. The organic residue is included in the material which remains behind after the emitter composition for formation is heat-treated. The first electrode is formed on a substrate(10). The emitter is formed on the first electrode.
Abstract:
An anode panel of a field emission type backlight unit and the field emission type backlight unit having the same are provided to improve luminance by increasing light utilization efficiency. An anode electrode(123) is formed on a lower surface of a substrate(121). A fluorescent substance layer(126) is applied to a lower surface of the anode electrode. A transparent cover(127) and a liquid pack(129) are prepared on an upper surface of the substrate. The transparent cover has lens-shaped curved units(127a). The liquid pack includes a transparent liquid filled in the curved units. The substrate is a transparent substrate. The anode electrode is made of a transparent conductive material. The anode electrode is made of ITO(Indium Tin Oxide). The transparent cover is made of synthetic resins. Spaces in the curved units are communicated with each other so that the transparent liquid circulates through the transparent cover. The transparent liquid is water or transparent oil.
