    • The invention relates to an LED package having a large beam angle of light emitted from an LED, simplifying a shape of a lens and an assembly process, and to a backlight unit using the same. The LED package includes a housing with a seating recess formed therein and at least one LED seated in the seating recess. The LED package also includes a lens having a predetermined sag on an upper side thereof, covering an upper part of the LED. The LED package and the backlight unit using the same can emit light uniformly without bright spots formed in an output screen, uses a simpler shaped lens with an increased beam angle, and minimizes a color mixing region to achieve miniaturization.
    • 本发明涉及一种LED封装,其具有从LED发射的大的光束角度,简化透镜的形状和组装过程,以及使用该LED封装的背光单元。 LED封装包括壳体,其具有形成在其中的座部凹部和位于座部凹部中的至少一个LED。 LED封装还包括在其上侧具有预定凹陷的透镜,覆盖LED的上部。 LED封装和使用该LED封装的背光单元可以均匀地发光而不会在输出屏幕中形成亮点,使用具有增大的光束角的更简单形状的透镜,并且使混色区域最小化以实现小型化。

    • Provided are an apparatus and method for writing data to a phase-change random access memory (PRAM) by using writing power calculation and data inversion functions, and more particularly, an apparatus and method for writing data which can minimize power consumption by calculating the power consumed while input original data or inverted data is written to a PRAM and storing the data consuming less power. A PRAM consumes a significant amount of power in order to store data in a memory cell since a large electric current is required to flow for a long period of time. According to the present invention, since the PRAM consumes different amounts of power when writing data with a value of 0 and data with a value of 1, the power consumed when input original data is stored and the power consumed when the input original data is inverted and stored are compared to each other, the data with a smaller power consumption is stored when the data is written to the PRAM as a word unit, and thus the power consumption of the PRAM can be reduced.
    • 提供了一种通过使用写入功率计算和数据反转功能将数据写入相变随机存取存储器(PRAM)的装置和方法,更具体地,涉及一种用于写入数据的装置和方法,该装置和方法可通过计算功率来最小化功耗 在输入原始数据或反相数据被写入PRAM并存储消耗较少功率的数据时消耗。 由于需要大电流长时间流动,所以PRAM消耗大量的功率以便将数据存储在存储单元中。 根据本发明,由于在写入值为0的数据和值为1的数据时,PRAM消耗不同的功率量,所以当输入原始数据被存储时消耗的功率和当输入的原始数据被反相时消耗的功率 并将其进行存储,将数据作为字单元写入PRAM时,存储具有较小功耗的数据,从而能够降低PRAM的功耗。
