Static field with line charge density in angular space of conductor electrostatics is formally described. 对导体平板构成的角域内具有线电荷密度的静电场进行了求解。
Since these modes are defined only by the method of addressing the array, the panel can switch between modes in less than one second. 因为这些模式被定为阵列的寻址方法，平板可以在不到一秒钟内在两种模式之间转换。
