A display apparatus and a manufacturing method of the display apparatus are provided. The display apparatus includes a substrate and a first sub-pixel located on the substrate. The first sub-pixel includes a first bottom electrode, a first light-emitting layer, and a first top electrode. The first light-emitting layer is located on the first bottom electrode. The first light-emitting layer includes a first groove structure or a first protrusion structure. The first top electrode is located on the first light-emitting layer.

Display apparatus and manufacturing method thereof

The present invention discloses a phosphorescent tris-chelated transition metal complex comprising i) two identical non-conjugated cyclometalated ligands being incorporated into a coordination sphere thereof with a transition metal, and one ligated chromophore being incorporated into the coordination sphere; or ii) one non-conjugated cyclometalated ligand forming a coordination sphere thereof with a transition metal, and two ligated chromophores being incorporated into the coordination sphere, wherein the metal is iridium, platinum, osmium or ruthenium, and the ligated chromophore possesses a relatively lower energy gap in comparison with that of the non-conjugated cyclometalated ligand, the latter afforded an effective barrier for inhibiting the ligand-to-ligand charge transfer process, so that a subsequent radiative decay from an excited state of these transition complexes will be confined to the single ligated chromophore. The architecture and energy gap of the ligated chromophore are suitable for generation of high efficiency blue, green and even red emissions.

Phosphorescent iridium complex with non-conjugated cyclometalated ligands, synthetic method of preparing the same and phosphorescent organic light emitting diode thereof

A series of noble metal organometallic complexes of the general formula (I): MLX(FBC), wherein M is a noble metal such as iridium, ruthenium or osmium, and L is a neutral ligand such as carbonyl, alkene or diene; X is an anionic ligand such as chloride, bromide, iodide and trifluoroacetate group; and FBC is a fluorinated bidentate chelate ligand such as beta diketonate, beta-ketoiminate, amino-alcoholate and amino-alcoholate ligand, wherein a is an integer of from zero (0) to three (3), b is an integer of from zero (0) to one (1) and c is an 10 integer of from one (1) to three (3). The resulting noble metal complexes possess enhanced volatility and thermal stability characteristics, and are suitable for chemical vapor deposition(CVD) applications. The corresponding noble metal complex is formed by treatment of the FBC ligand with a less volatile metal halide. Also disclosed are CVD methods for using the noble metal complexes as source reagents for deposition of noble metal-containing films such as Ir, Ru and Os, or even metal oxide film materials IrO, OsOand RuO.
