    • A method, apparatus, and system for encoding or decoding a broadband voice signal are provided. The method includes extracting a linear prediction coefficient (LPC) from the broadband voice signal; outputting a linear prediction (LP) residual signal; pitch-searching a spectrum of the LP residual signal; extracting spectral magnitudes and phases of the LP residual signal, which correspond to a damping factor; obtaining, from among the extracted spectral magnitudes and phases, a first spectral magnitude and a first phase at which a power value of the LP residual signal is minimized; quantizing the first spectral magnitude and the first phase; and decoding the broadband voice signal. The apparatus includes a linear prediction coefficient (LPC) analyzer; an LPC inverse filter; a pitch searching unit; a sinusoidal analyzer; and a phase and spectral magnitude quantizer. The system includes a broadband voice encoding apparatus and a broadband voice decoding apparatus.

    • A display substrate includes a plurality of gate wirings, a plurality of source wirings, a plurality of pixel portions, an electrical short pad part and a short element. The electrical short pad part is formed in a peripheral area surrounding the display area and formed from at least one of the gate metallic layer and the source metallic layer to receive a common voltage. The short element makes contact with the electrical short pad part and has electric conductivity. The electrical short pad part includes a first metallic layer and a second metallic layer in sequence, and the second metallic layer has greater ionization energy than the first metallic layer. The electrical short pad part is exposed onto the surface of the display substrate. Accordingly, an extra cover electrode for preventing the electrical short pad part from corrosion may be omitted, so that static electricity is prevented from being applied into the display substrate.
    • 显示基板包括多个栅极布线,多个源极布线,多个像素部分,电短焊盘部分和短元件。 电短焊盘部分形成在围绕显示区域的周边区域中,并由栅极金属层和源极金属层中的至少一个形成,以接收公共电压。 短元件与电短焊盘部分接触并具有导电性。 电短衬垫部分依次包括第一金属层和第二金属层,并且第二金属层具有比第一金属层更大的电离能。 电短焊盘部分暴露在显示基板的表面上。 因此,可以省略用于防止电短衬垫部分腐蚀的额外的覆盖电极,从而防止静电施加到显示基板。
