  • Publication number: 20220261110
    Abstract: The present invention relates to a terminal comprising a display, a central processing device, and an input device. When a phase operating command for distinguishing phases is inputted on the display, the input device outputs the phase operating command, and the central processing device recognizes the phase of the phase operating command and outputs information which matches the recognized phase to the display. Thus, information which is associated with information displayed on the current screen can be effectively displayed on a display screen even without executing several screen changing commands.

    Abstract: A semiconductor light emitting device may include a light emitting package. A light emitting package may include a light emitting stack including a sequential stack of a first conductivity type semiconductor layer, an active layer, and a second conductivity type semiconductor layer. An encapsulation layer may at least partially surround the second conductivity type semiconductor layer, and a wavelength conversion layer may cover the first conductivity type semiconductor layer. One or more of the encapsulation layer and the wavelength conversion layer may have a greater coefficient of thermal expansion (CTE) than a GaN-based compound semiconductor. The semiconductor light emitting device may include a stress applying structure that may apply a tensile stress to the light emitting stack. The light emitting stack may have reduced thermal droop at an operation temperature and improved luminous efficiency.
