    • Provided are a method for preparing metallic nickel powders capable of decreasing the content of an alkaline metal in the metallic nickel powders, metallic nickel powders with the low content of an alkaline metal, a conductive paste including metallic nickel powders with the low content of an alkaline metal, and a multi-layer ceramic capacitor (MLCC) including a nickel inner electrode with the low content of an alkaline metal. The method for preparing the metallic nickel powders includes heating a mixture including an organic base, a nickel precursor compound, and a polyol. Wherein, the nickel precursor compound is converted to the metallic nickel powders through reduction by the organic base and the polyol. In the method, the organic base is used instead of the hydroxide of an alkaline metal such as NaOH and KOH. Therefore, the content of an alkaline metal such as sodium and potassium that can be incorporated as an impurity into the metallic nickel powders can be significantly reduced.
    • 提供了一种能够降低金属镍粉末中的碱金属含量的金属镍粉末的方法,碱金属含量低的金属镍粉末,含有碱性低的金属镍粉末的导电膏 金属和包含碱金属含量低的镍内电极的多层陶瓷电容器(MLCC)。 制备金属镍粉末的方法包括加热包括有机碱,镍前体化合物和多元醇的混合物。 其中,镍前体化合物通过有机碱和多元醇的还原转化为金属镍粉末。 在该方法中,使用有机碱代替NaOH和KOH等碱金属的氢氧化物。 因此,可以显着降低作为杂质掺入到金属镍粉末中的碱金属如钠和钾的含量。

    • A display driver and display driving method process display data received from a central processing unit (CPU) and output display data voltages. The display driver includes a synchronization controller that sends a reference synchronization signal to the CPU, and controls the CPU to synchronize a write clock with the reference synchronization signal and to send the write clock. A write clock detector detects whether the write clock is received from the CPU and outputs a selection signal in response. A frame memory receives and stores display data of a current frame synchronized with the write clock. A gray-level compensator generates gray-level compensated display data based on the display data of a current frame and display data of a previous frame previously stored in the frame memory. A selector outputs one of the gray-level compensated display data or the display data previously stored in the frame memory as scan data in response to the selection signal.
    • 显示驱动器和显示驱动方法处理从中央处理单元(CPU)接收的显示数据并输出显示数据电压。 显示驱动器包括同步控制器,其向CPU发送参考同步信号,并且控制CPU将写入时钟与参考同步信号同步并发送写入时钟。 写入时钟检测器检测是否从CPU接收到写入时钟并且响应地输出选择信号。 帧存储器接收并存储与写入时钟同步的当前帧的显示数据。 灰度级补偿器基于当前帧的显示数据和先前存储在帧存储器中的先前帧的显示数据生成灰度补偿显示数据。 响应于选择信号,选择器输出灰度级补偿显示数据之一或先前存储在帧存储器中的显示数据作为扫描数据。
