| titleOfInvention | Writing board and writing device therewith |
| abstract | The invention discloses a writing board comprising a first electrode layer, a writing layer, a second electrode layer and an internal light source, wherein the first electrode layer and the second electrode layer are respectively positioned on two opposite sides of the writing layer and used for providing voltage for the writing layer; the writing layer is made of material of the photochromic properties and the electroluminescence properties, the writing layer can be subjected to structural change under the irradiation of the internal light source to lose the electroluminescence properties, and the writing layer can restore the structure with the electroluminescence properties under the irradiation of the external light source; and thus, the writing board forms a luminescence track corresponding to an external light source irradiation track. |
