Abstract: A display panel disposes a first display area and a second display area. The display panel includes a plurality of OLED pixel units disposed in the first display area, and a plurality of Micro LED pixel units disposed in the second display area. By replacing the OLED pixel units corresponding to the under-screen camera or used to display a fixed picture with the Micro LED pixel units, the image quality of an under-screen camera can be improved, and the burning screen problem caused by displaying the same picture for a long time can be solved.

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.
