  • Patent number: 11963403
    Abstract: A display device includes a first substrate. A transistor is disposed on the first substrate. A light-emitting element is connected to the transistor. An insulating layer is disposed between the transistor and the light-emitting element. A second substrate at least partially overlaps the first substrate. A color conversion layer is disposed on the second substrate. The insulating layer includes a first insulating layer and a second insulating layer. A distance between the first insulating layer and the first substrate is less than a distance between the second insulating layer and the first substrate. The first insulating layer includes a light blocking material.

  • Patent number: 10252723
    Abstract: A slip factor learning method of a dual clutch transmission (DCT) may include: determining, by a control unit, whether the DCT is up-shifted or down-shifted; comparing an engine speed to a shift start reference speed, and determining whether the engine speed enters an actual gear shifting period or actual gear shifting is completed, in response to the determined type of the gear shifting; comparing a magnitude of an engine torque to a magnitude of a clutch torque at a point of time that the engine speed enters the actual gear shifting period or the actual gear shifting is completed; and learning a slip factor at the point of time that the engine speed enters the actual gear shifting period or the actual gear shifting is completed, based on the magnitude comparison result between the engine torque and the clutch torque.

  • Patent number: 10125861
    Abstract: The present invention relates to a method and apparatus for controlling a transmission of a vehicle and, more particularly, to a method and apparatus for controlling synchronization of a synchronizer included in a transmission. The method includes determining a speed change mode of a vehicle and a target time corresponding to the speed change mode; calculating a difference in speed between an input shaft and an output shaft with respect to a current time; calculating a speed increment or decrement of the output shaft from the current time to the target time; calculating a synchronization torque using the difference in speed and the speed increment or decrement; determining a target displacement of a synchronizer using the synchronization torque; and controlling the synchronizer according to the target displacement and recognizing a sleeve with a clutch gear.
