Publication number: 20240143931Abstract: Disclosed herein is a system that automatically correlates related instances of written feedback associated with a computer product to relevant telemetry data so that a performance and/or reliability issue associated with the computer product can be identified and fixed in a more efficient manner. The system applies a natural language processing model to instances of written feedback that have been received for the computer product to identify a cluster of instances of written feedback which describe the same issue. For each instance of written feedback in the cluster, the system uses an identification and a timestamp to retrieve a telemetry event log. The system analyzes the telemetry event logs to identify a common telemetry event. This effectively correlates meaningful written descriptions with common telemetry behavior(s). Information regarding this correlation is provided to a computing device of a user (e.g., a developer) tasked with examining the performance and/or reliability issue.Type: ApplicationFiled: October 26, 2022Publication date: May 2, 2024Inventors: Ryan Sung Jun BAE, Prachur BHARGAVA, Anjali S.

Patent number: 9362516Abstract: An organic light emitting device including a plurality of organic layers between a first electrode and an emitting layer, wherein the organic layer includes an electron blocking layer. In one embodiment, a first organic layer, an electron blocking layer, a second organic layer and an emitting layer are formed on the first electrode. The electron blocking layer has a Lowest Unoccupied Molecular Orbital (LUMO) level which is lower than that of the first organic layer. Thus, the electron blocking layer traps excess electrons injected from the emitting layer, thereby improving lifetime characteristics of the OLED.Type: GrantFiled: June 5, 2015Date of Patent: June 7, 2016Assignee: Samsung Display Co., Ltd.Inventors: Ji-Hwan Yoon, Kwan-Hee Lee, Sung-Jun Bae
