Provided is an organic light-emitting diode display device () in which an anode electrode () extends to cover sides of a reflective metal () below the anode electrode ().

Organic light-emitting diode display device and manufacturing method thereof

An organic light emitting display device in which a sidewall of a reflective metal layer in a blue pixel region is covered with an inorganic film and in which the reflective metal layer is thus prevented from being damaged or rendered defective when performing subsequent processes, such as etching and cleaning, for forming an anode on the reflective metal layer.

Organic emitting display device having reflective metal layers on different levels above red, green and blue pixel regions and method of manufacturing same

A hydrochromic polydiacetylene polymer patch and a method of manufacturing the same are provided. The hydrochromic polymer patch comprises a polymer matrix; and polydiacetylene present in the polymer matrix. The polydiacetylene has an ionic functional group in the repeating unit thereof. The ionic functional group is RMor RX. Ris a carboxylate anion, Mis an alkali metal cation, and Ris a quaternary ammonium group, and Xis F, Cl, Br, I, PF, BF, bis(trifluoromethane)sulfonimide (TfN), trifluoromethanesulfonate (TfO), SCN, or CHCOO.

Hydrochromic polydiacetylene polymer patch and method of manufacturing the same

A water-based ink comprising a diacetylene monomer, a hydrochromic polydiacetylene paper prepared using the ink, and uses therefor are provided. The water-based ink includes a diacetylene monomer, and a solvent mixture comprising water and an alcohol. The diacetylene monomer has a ionic functional group represented by RX, wherein Xis F, Cl, Br, I, PF, BF, bis(trifluoromethane)sulfonimide (TFSI) (TfN), trifluoromethanesulfonate (TfO), SCN, or CHCOO, and Ris N&#x2014;R-heterocyclic quaternary ammonium.

Water-based diacetylene ink, hydrochromic polydiacetylene paper prepared using the ink, and use thereof

The present invention relates to a hydrochromic polydiacetylene composite composition, a hydrochromic thin film using same, and a use thereof, and more specifically, to a hydrochromic polydiacetylene composite composition reacting sensitively to moisture, providing the hydrochromic thin film using same, and to applying same to biorecognition or fingerprint recognition. According to the present invention, moisture secreted from a fingerprint or pores on the skin can be detected with high sensitivity. Thus, the position of pores unique to a fingerprint of an organism can be amplified and displayed through selective color change and fluorescent change patterns exhibited when moisture is absorbed.
