    • The present invention relates to a porous polyurea material and a method for preparing the same. The porous polyurea material may be prepared by polymerization and crosslinking of tetra(4-aminophenyl)methane with a monomer two to four isocyanate (—NCO) groups. The method includes: mixing an organic solution of tetra(4-aminophenyl)methane with an organic solution of a monomer having two to four isocyanate groups; reacting the mixed solution under a nitrogen atmosphere; and drying a semi-solid or solid material formed by gelation of the reaction solution, or adding the reaction solution to a non-solvent before gelation of the reaction solution to form a precipitate, followed by drying, or applying the reaction solution to a substrate before gelation of the reaction solution, followed by drying. According to the present invention, the introduction of the monomer having a tetrahedral structure can impart good chemical resistance, heat resistance and durability to the porous polyurea material.

    • A porous polyurea material may be prepared by polymerization and crosslinking of tetra(4-aminophenyl)methane or tetra(4-aminophenyl)silane with a monomer having two to four isocyanate (—NCO) groups, or by polymerization and crosslinking of tetra(4-isocyanatophenyl)methane or tetra(4-isocyanatophenyl)silane with a monomer having two to four amino groups. The method includes: mixing an organic solution of tetra(4-aminophenyl)methane with an organic solution of a monomer having two to four isocyanate groups; reacting the mixed solution under a nitrogen atmosphere; and drying a semi-solid or solid material formed by gelation of the reaction solution, or adding the reaction solution to a non-solvent before gelation of the reaction solution to form a precipitate, followed by drying, or applying the reaction solution to a substrate before gelation of the reaction solution, followed by drying.

    • In a control board and a display apparatus, the control board includes a timing controller, and first and second connectors. The timing controller receives a first external image control signal having one of a first and a second frequency, and selectively receives a second external image control signal having the first frequency when the first external image control signal has the first frequency. The timing controller selects one of the first and second frequencies based on the first and second external image control signals to output an image driving signal. The first connector connects the timing controller to an external video system to transfer the first external image control signal to the timing controller. The second connector connects the timing controller to the external video system to transfer the second external image control signal to the timing controller. Thus, the control board is commonly used in the first and second frequencies.
    • 在控制板和显示装置中,控制板包括定时控制器以及第一和第二连接器。 定时控制器接收具有第一和第二频率之一的第一外部图像控制信号,并且当第一外部图像控制信号具有第一频率时选择性地接收具有第一频率的第二外部图像控制信号。 定时控制器基于第一和第二外部图像控制信号选择第一和第二频率中的一个,以输出图像驱动信号。 第一个连接器将定时控制器连接到外部视频系统,以将第一外部图像控制信号传输到定时控制器。 第二连接器将定时控制器连接到外部视频系统,以将第二外部图像控制信号传送到定时控制器。 因此,控制板通常用于第一和第二频率。
