Abstract: A liquid crystal display and its array substrate are disclosed. The array substrate includes a number of scan lines, a number of data lines, and a number of pixels arranged in an array. Each pixel includes four sub-pixels disposed in two lines and two columns. The four sub-pixels are red, green, blue, and white sub-pixels. Each sub-pixel is connected to a thin film transistor (TFT). The TFTs are driven by the data and scan lines. Any two sub-pixels of a same color on two neighboring lines and on two neighboring columns have reversed polarities.

Abstract: An electromagnetic touch device and an electromagnetic touch screen are provided. The electromagnetic touch device includes the electromagnetic touch screen. The electromagnetic touch screen is coupled with a stylus. The electromagnetic touch screen includes transmitting coils and receiving coils. The transmitting coils are correspondingly arranged in a peripheral area around the receiving coils. During interaction between the stylus and the electromagnetic touch screen, the transmitting coils transmit transmitting signals to generate a first magnetic field through which the stylus is charged. When a touch operation is performed, the receiving coils generate receiving signals according to a second magnetic field generated by the stylus, a touch point of the stylus is obtained according to the receiving signals.
