[Embodiment] The present invention will be further described in detail below with reference to the accompanying drawings. The display device according to the first embodiment of the present invention includes a magnetic pen 11 and a display module 12, and the display module U includes a display unit (10) of 8 200847085 plural king arrays. The magnetic pen η includes a first One end 4 112 and a second end portion 114 opposite to the first end portion 112, the fourth end 112 is a drain, and the second end portion 114 is an S pole. The magnetic pen 11 ' can be rounded The square or other shape is preferably a user-friendly and ergonomic shape. In the present embodiment, the magnetic pen 11 has a cylindrical pen-shaped structure. Referring to FIG. 2 and FIG. 3, the display unit 120 includes a light-emitting unit 121', a switch unit 122, and a fixing plate 123. The light-emitting unit 121 is not disposed on one side of the fixed plate 123. The switch unit The 122 is disposed in the fixing plate 123 and opposite to the light emitting unit 121. The light emitting unit 121 includes a first electrode 1211, a second electrode 1212', an illuminant 1213, a wire 1214, and a reflector 1215. The first electrode 1211 and the second electrode 1212 are disposed in parallel with the bottom of the reflector 1215 and connected to the fixing plate 123. The illuminant 1213 is disposed on the first electrode 1211 and opposite to the fixing plate 123. • Both ends of 1214 are respectively connected to the illuminant 1213 and the second electrode 1212. The illuminant 1213 has an opening 1216 above the wire 1214, that is, away from the side of the fixing plate 123. The opening 1216 can be filled with a transparent colloid 1217. The illuminant 1213 may be a Light Emitting Diode (LED), an Organic Light Emitting Diode (OLED) or other electroluminescent element. In this embodiment, the illuminant 1213 is an LED. . The opening 1216 can be circular, square or other shape suitable for actual needs. The reflector 1215 can reflect the light emitted by the body 1213, such that the light exits the opening 1216 better. The switch unit 122 includes a switching element 1221 connected to the first electrode 1211 and a magnet 1222 adjacent to the switching element 1221. The opening and closing member 1221 is made of a conductive material, and includes a first fixing piece m3, a first fixing piece 1225 and an elastic piece 1227. The first fixing piece 1223 is opposite to the second fixing piece 1225. One end of the first fixing piece 1223 is connected to the first electrode 1211, and one end of the elastic piece 1227 is connected to one end of the second fixing piece i225, and the other end of the elastic piece 1227 can be combined with the first fixing piece 1223. One end of the second fixing piece 1225 is connected to the external power source, and the other end of the elastic piece 1227 is separated from the other end of the first fixing piece 1223 without being subjected to an external force. It can be understood that the second fixing piece 1225 and the elastic piece 1227 can be a unitary structure. The magnet 1222 can be a ferrite magnet, an alnico magnet, a neodymium magnet or a samarium cobalt magnet. In the present embodiment, the magnet 1222 is a ferrite magnet; the magnet 1222 can be cylindrical, square. Or other shapes, in the present embodiment, the magnet 1222 is cylindrical. The fixing plate 123 has a receiving portion 1231. The receiving portion 1231 is disposed on a side opposite to the light emitting unit 121. The switching element 1221 is located at a side wall of the receiving portion 1231. The magnet 1222 is disposed in the receiving portion ι231. The distal magnet 1222 is in contact with the second fixing piece 1225 when it is not subjected to an applied magnetic force. When the second electrode 1212 is connected to a positive voltage, and the second fixing piece 1225 of the switching element 1221 is connected to a negative voltage, the first end 112 of the magnetic pen 11 is adjacent to the illuminant 1213 and the illuminant When the 1213 is adjacent to each other, the magnet 1222 moves to the illuminator along the accommodating portion 1231 of the fixing plate 123 in a manner close to the magnetic pen 11 under the force of the opposite attraction of the first end portion 112. Below the 1213, the elastic piece 1227 of the switching element 1221 is brought into contact with the first fixing piece 1223, so that the electrical circuit in which the illuminating body 1213 is placed is turned on to illuminate, so the first of the magnetic pen 11 ^ After the end portion 112 is close to the different display unit 120, the illuminant 1213 included in the different display unit 120 is illuminated, so that the image formed by the illuminating display unit 120 is the information to be displayed. It can be seen that the display device 10 displays information by illuminating the image formed by the plurality of display units 120 included in the display module 12, and does not require chalk or a whiteboard pen, thereby not detrimental to human health and environmental pollution. In addition, when the second end 114 of the magnetic pen 11 is adjacent to the illuminated illuminator 1213 and adjacent to the illuminating illuminator 1213, the magnet 1222 will be at the second end 114. When the accommodating portion 1231 of the fixing plate 123 moves away from the magnetic pen 11 to be in contact with the second fixing piece 1225, the elastic piece 1227 of the switching element 1221 pops up to The first fixing piece 1223 is separated, so that the electrical circuit in which the illuminant 1213 is located is disconnected and turned off, so that the second end portion 114 of the magnetic pen 11 is close to the different illuminated display unit 120. The illuminants 1213 included in the different illuminated display units 120 are turned off, so that the image formed by the illuminated display unit 120, that is, the information displayed by π 200847085, is erased. Referring to FIG. 4 and FIG. 5 simultaneously, the display device 20' provided by the second embodiment of the present invention is substantially the same as the display device 1' provided in the first embodiment. The difference is that the display device 20 is different. A plurality of display units 220 arranged in an array are included. One end of the second fixing piece 1225 is connected to the first electrode 1211, and the other end of the second fixing piece 1225 is connected to one end of the elastic piece 1227.
