  • Publication number: 20240153459
    Abstract: A display device includes a display panel including a pixel and a sensor pixel, the pixel including a light emitting element and a driving transistor controlling a current flowing through the light emitting element, the sensor pixel including sensor transistors, a data driver that supplies a data signal to the pixel through a data line and provides a sensor data signal to the sensor pixel through a sensor data line, and a sensing driver that obtains sensing information on a current flowing through the sensor pixel. The sensor transistors are electrically connected in parallel to each other and are commonly electrically connected to the sensor data line. The sensor transistors and the driving transistor include a substantially same characteristic.

  • Patent number: 11582391
    Abstract: An electronic device includes a first camera, a second camera, a display, a memory, and a processor. The processor collects a first image obtained by the first camera with respect to an external object and a second image obtained by the second camera with respect to the external object, generates a third image with respect to the external object using a first area of the first image and a second area of the second image, which corresponds to the first area, identifies an input associated with the third image displayed through the display, and displays an image generated using at least one of the first image, the second image, or depth information in response to the input. The generating operation of the third image includes generating the depth information with respect to the third image.

  • Publication number: 20180284979
    Abstract: An electronic device is provided. The electronic device includes a display, at least one processor, and a memory, wherein the memory is configured to store instructions that, when executed by the electronic device, cause the at least one processor to control the display to display a first icon relating to image capture, enable a preset function and control the display to display a first object representing an execution step of the preset function, in response to movement of the first icon by a predetermined distance in a first direction, and execute the preset function and control the display to modify and display the first object, in response to movement of the first icon beyond the predetermined distance.

  • Patent number: 8355743
    Abstract: In a Push-To-Talk (PTT) communication method, during a PTT conversation between multiple mobile terminals in a PTT chat-room, a first mobile terminal specifies a second mobile terminal as a target for a forced leave and makes a request to a PTT server for a forced leave of the second mobile terminal. The PTT server forces the second mobile terminal to leave the PTT chat-room. During a PTT chat-room conversation, a disruptive member can be forced to leave the PTT chat room and is not allowed to later re-join the PTT chat room. Thus, it is possible to more smoothly run a PTT chat room in a manner fitting for the purpose, enhancing user convenience.
