    • A black matrix, a method for preparing the black matrix, a flat panel display and an electromagnetic interference filter using the black matrix. The black matrix may comprise a substrate, a titanium oxide layer, a Ni plating layer, and a Ni/Pd alloy layer. The method may comprise the steps of forming a titanium oxide layer, forming a metal particle-deposited pattern on the titanium oxide layer, forming a Ni electroless plating layer on the metal particle-deposited pattern, and forming a Ni/Pd alloy layer on the Ni electroless plating layer. Since the black matrix may have a high blackening density via simple selective multilayer plating without using a high-price vacuum sputtering apparatus and undergoing photolithography, unlike conventional chromium-based black matrices, it may be employed in various flat panel displays. In addition, since the black matrix may exhibit superior electrical conductivity, it may be used in electromagnetic interference filters without additional front-surface blackening.
    • 黑矩阵,黑矩阵的制备方法,平板显示器和使用黑矩阵的电磁干扰滤波器。 黑色矩阵可以包括基底,氧化钛层,Ni镀层和Ni / Pd合金层。 该方法可以包括以下步骤:在氧化钛层上形成氧化钛层,形成金属颗粒沉积图案,在金属颗粒沉积图案上形成Ni化学镀层,并在其上形成Ni / Pd合金层 镍化学镀层。 由于黑色矩阵可以通过简单的选择性多层电镀具有高的黑化密度,而不使用高价格的真空溅射装置并进行光刻,与常规的铬基黑色矩阵不同,可以用于各种平板显示器。 此外,由于黑矩阵可以表现出优异的导电性,所以它可以用于电磁干扰滤光器中,而没有额外的前表面变黑。
