    • 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.
    • 本发明涉及一种多孔聚脲材料及其制备方法。 多孔聚脲材料可以通过四(4-氨基苯基)甲烷与单体二至四个异氰酸酯(-NCO)基团的聚合和交联来制备。 该方法包括:将四(4-氨基苯基)甲烷的有机溶液与具有2-4个异氰酸酯基团的单体的有机溶液混合; 在氮气氛下使混合溶液反应; 并干燥通过反应溶液的凝胶化形成的半固体或固体物质,或在将反应溶液凝胶化之前将反应溶液加入到非溶剂中以形成沉淀物,然后干燥,或将反应溶液施用于基材 在反应溶液凝胶化之前,然后干燥。 根据本发明,引入具有四面体结构的单体可以赋予多孔聚脲材料良好的耐化学性,耐热性和耐久性。

    • 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。
