The patent application discusses an organometallic compound and its integration into organic light-emitting devices (OLEDs) and electronic apparatuses. These OLEDs exhibit superior characteristics such as wide viewing angles, high contrast ratios, and fast response times. The core of the invention is the use of a specific organometallic compound represented by Formula 1, which enhances the performance of OLEDs by facilitating efficient light emission through the recombination of carriers in the emission layer.
Organic light-emitting devices are self-emissive and offer advantages over traditional displays, including better luminance and lower driving voltages. Typically, an OLED structure includes a substrate with a first electrode, a hole transport region, an emission layer, an electron transport region, and a second electrode. The organometallic compound is integrated into the emission layer to improve exciton formation and light emission efficiency.
The organometallic compound is detailed through chemical formulas. In Formula 1, M1 can be metals like platinum, palladium, or gold. Ar1 is defined by Formula 2, with Z1 and Z2 being various alkyl or aryl groups. The compound's structure allows for flexibility in its chemical composition, enabling it to be tailored for specific OLED applications.
The chemical structure of the organometallic compound includes numerous variables such as k1, k2, A10 to A40, Y10 to Y30, T1 to T4, L11 to L13, and others. These variables define the bonding sites and the types of chemical bonds present within the compound. The flexibility in these variables allows for customization to enhance specific properties of OLEDs.
This organometallic compound can be used in various electronic devices that incorporate OLED technology. Its integration into consumer products promises improved display characteristics due to its ability to efficiently manage exciton transitions and light emission. This results in better energy efficiency and potentially longer device lifespans.
