  • Patent number: 12207498
    Abstract: An object of the present disclosure is to implement a coloring pattern with a constant illuminance value on an electrode substrate to thereby increase display reliability and lifetime while reducing delamination of the hole transport layer (HTL) in the post-process. That is, when the roughness of the pattern after post-baking treatment is low, it may cause delamination of the hole transport layer (HTL) and a decrease in lifetime due to defective pixels, and thus a certain roughness can be obtained by minimizing the surface flow by leaving the substrate at a high temperature during post-baking treatment according to the present disclosure.

  • Patent number: 11575772
    Abstract: A group-based communication platform is configured to initialize processing actions executable via validated external resources. Moreover, the group-based communication platform may recommend specific processing actions to a user based at least in part on the user's activity in interacting with the group-based communication platform (e.g., via a client device), wherein such activity may be represented as environmental contextual data. Moreover, once the user selects a particular processing action for execution, the group-based communication retrieves at least a portion of the generated environmental contextual data to be passed to the validated external resource for use in executing the selected processing action.

    Abstract: An electronic device includes a semiconductor memory. The semiconductor memory includes word lines, bit lines intersecting the word lines, and memory cells coupled to and disposed between the word lines and the bit lines, each of the memory cells including a variable resistance layer in an amorphous state regardless of a value of data stored in the memory cells. In a reset operation, a memory cell is programmed to a high-resistance amorphous state by applying, to the memory cell, a sub-threshold voltage that is lower than a lowest threshold voltage among threshold voltages of the memory cells.
