    • The present invention is related to an apparatus and a method for controlling operations of low sound output in an audio system. Embodiments of an apparatus and a method for controlling an operation of an audio woofer in a machine provided with an audio system such as a portable computer can operate using at least one or more information of an audio data type, an audio signal, an audio channel number and a power source. Therefore, it is possible to accurately select and listen to an audio of a high-pass component only by stopping operations of a low-pass component for an audio as reproduced. In addition, embodiments of the present invention can extend a time for using a battery by controlling operations of a woofer, when using the battery power.
    • 本发明涉及一种用于控制音频系统中低声音输出的操作的装置和方法。 用于控制设置有诸如便携式计算机的音频系统的机器中的音频低音扬声器的操作的装置和方法的实施例可以使用音频数据类型,音频信号,音频信道的至少一个或多个信息来操作 数量和电源。 因此,只有通过停止对再现的音频的低通分量的操作,才能准确地选择和收听高通分量的音频。 此外,本发明的实施例在使用电池电力时可以通过控制低音扬声器的操作来延长使用电池的时间。

    • An exemplary embodiment of the present invention discloses a light emitting diode including a substrate having a first edge and a second edge opposite to each other, a light emitting structure disposed on the substrate, the light emitting structure including a first semiconductor layer and a second semiconductor layer, a plurality of first electrode pads arranged on an upper surface of the first semiconductor layer, the first electrode pads arranged in a vicinity of the first edge, a plurality of second electrode pads arranged on the second semiconductor layer, the second electrode pads arranged in a vicinity of the second edge, a plurality of first extensions, each first extension extending from a first electrode pad, and a plurality of second extensions, each second extension extending from a second electrode pad. The first extensions include intrusion parts extending in a direction from the first edge to the second edge, wherein the intrusion parts are spaced apart from each other and not connecting with the second electrode pads. Further, the second extensions include intrusion parts extending in a direction from the second edge to the first edge, wherein the first extension intrusion parts each extend into a region between two of the second extension intrusion parts.
    • 本发明的一个示例性实施例公开了一种发光二极管,其包括具有彼此相对的第一边缘和第二边缘的基板,设置在基板上的发光结构,所述发光结构包括第一半导体层和第二半导体 布置在第一半导体层的上表面上的多个第一电极焊盘,布置在第一边缘附近的第一电极焊盘,布置在第二半导体层上的多个第二电极焊盘,布置在第二半导体层上的第二电极焊盘 在第二边缘附近,多个第一延伸部,每个第一延伸部从第一电极焊盘延伸,以及多个第二延伸部,每个第二延伸部从第二电极焊盘延伸。 第一延伸部包括在从第一边缘到第二边缘的方向上延伸的侵入部分,其中入侵部分彼此间隔开并且不与第二电极焊盘连接。 此外,第二延伸部包括在从第二边缘到第一边缘的方向上延伸的侵入部分,其中第一延伸入侵部分各自延伸到两个第二延伸入侵部分之间的区域中。
