You should be familiar with Gobang. Let's play a game, using black chessmen to represent the frame of Chinese characters and white chessmen to represent other blank areas of Chinese characters. The game shows that to spell a complete Chinese character, a total of 256 black and white chessmen are required. If we change the chessmen into LED, turn on the diode in the black chessmen area, and turn off the diode in the white chessmen area, An electronic Chinese character is written. Isn't it a bit magical!
