Background
With the popularization of 5G, intelligent education and paperless office, digital writing is already reflected in our eyelids. When the electronic pen is used for writing, handwriting is displayed on the transparent antenna plate. However, the handwriting transparent antenna board mode in the prior art is easily interfered by the outside, and particularly, four edge signals of the prior transparent antenna board are affected by an iron frame of a screen, the signals become very weak, and the edge jitter is more severe during writing. The main reason is that the metal wires used by the screen are thick, shadows appear after the screen is lightened, and certain influence is exerted on the vision of a user. The eyes of the user may be injured by the long-term use. Although it is only one-area type, it cannot write the original handwriting normally if it is interfered by the outside and the shadow affects the vision. Thereby causing a waste of resources.
