Abstract: An electroluminescent device includes a first electrode and a second electrode facing each other; an emission layer disposed between the first electrode and the second electrode and including a plurality of quantum dots and a first hole transporting material having a substituted or unsubstituted C4 to C20 alkyl group attached to a backbone structure; a hole transport layer disposed between the emission layer and the first electrode and including a second hole transporting material; and an electron transport layer disposed between the emission layer and the second electrode.

Abstract: A quantum dot light-emitting device including first electrode and a second electrode, a quantum dot layer between the first electrode and the second electrode, a first electron transport layer and a second electron layer disposed between the quantum dot layer and the second electrode. The second electron transport layer is disposed between the quantum dot layer and the first electron transport layer, wherein each of the first electron transport layer and the second electron transport layer includes an inorganic material. A lowest unoccupied molecular orbital energy level of the second electron transport layer is shallower than a lowest unoccupied molecular orbital energy level of the first electron transport layer, and a lowest unoccupied molecular orbital energy level of the quantum dot layer is shallower than a lowest unoccupied molecular orbital energy level of the second electron transport layer. An electronic device including the quantum dot light-emitting device.

Abstract: The present invention relates to a system and method for unidirectional data transmission. Data is unidirectionally transmitted from a network having a higher security level to a network having a lower security level and a corresponding data verification result is received through a separate line. Hence, it is possible not only to physically block access to the network having a higher security level from the network having a lower security level but also to improve reliability of data delivery by appropriately handling packet loss and bit errors that may occur during data transmission.

Abstract: Provided are an apparatus and method for detecting a Dynamic Link Library (DLL) inserted by a malicious code. The method includes collecting first DLL information from an image file of a process before the process is executed; collecting second DLL information loaded into a memory as the process is executed; comparing the first DLL information with the second DLL information to extract information on an explicit DLL; and determining whether the explicit DLL is a DLL inserted by a malicious code or not.
