  • Patent number: 12004397
    Abstract: A display apparatus includes a substrate including a display area, a peripheral area surrounding the display area, a function-adding area, of which at least a portion is surrounded by the display area, and a detour area disposed between the display area and the function-adding area. The display apparatus includes a plurality of pixel circuits disposed in the display area. A plurality of driving lines are electrically connected to the pixel circuits and extend in a direction in the display area. A first detour line is disposed in the detour area and is electrically connected to a first driving line. A second detour line is disposed in the detour area. The second detour line is electrically connected to a second driving line and is disposed in a different layer from the first detour line.

  • Publication number: 20240166016
    Abstract: A vehicular air conditioning system includes: a refrigerant circulation line including first and second evaporators through which refrigerant can flow in a cooling mode, and first and second expansion valves configured to depressurize and expand the refrigerant introduced into each of the first and second evaporators; and refrigerant flow control part provided in front of the first evaporator and the first expansion valve and configured to control refrigerant flow. The first evaporator is used for cooling rear seat region of a passenger room and the refrigerant flow control part is configured to supply and block the refrigerant with respect to the first evaporator and the first expansion valve and is configured to block the refrigerant when the cooling governed by the first evaporator is controlled in a turn-off mode and supply the refrigerant to the first evaporator and the first expansion valve depending on the on/off condition of the cooling governed by the second evaporator.

  • Publication number: 20240107869
    Abstract: A display device includes a display area, a test pad, a plurality of first test transistors, and at least one outline. The display area includes pixels coupled to data lines and scan lines. The test pad receives a test signal. The first test transistors are coupled between the data lines of the display area and the test pad. The at least one outline is coupled between one of the first test transistors and the test pad. The at least one outline is located in a non-display area outside the display area.

  • Publication number: 20110034148
    Abstract: Disclosed are an apparatus and a method for detecting whether a content executed in a mobile platform of mobile communication terminal perform a communication operation without a user's reservation or permission, thereby preventing an unexpected communication operation. In this invention, if a content performs the communication operation due to its malfunction by a computer virus or a program error, the communication operation, such as voice calling or message transmission to unspecified communication terminal or access to arbitrary wireless internet server, is detected and interrupted. With the interruption of the unexpected communication operation, the user's damage, such as the payment of charges for communication services, is previously prevented. In case of the interruption of the communication operation, the user is informed of the erroneous content and the performed communication operation so that the user selects the corresponding contents to be deleted or preserved.
