Electroluminescence sheet and luminous writing board using electroluminescence sheet

Abstract

The invention discloses an electroluminescence sheet and a luminous writing board using the electroluminescence sheet. The electroluminescence sheet comprises a first body, a base material layer and aheat dissipation base, wherein the first body is arranged at the upper end of the base material layer and is in bonding fit with the upper end of the base material layer, and the first body and the base material layer are inserted into the heat dissipation base matched with the first body and the base material layer. The luminous writing board comprises a second body matched with the electroluminescent sheet in an inserted mode. A writing board body matched with the electroluminescent sheet for use is arranged on the second body. A cleaning device used for automatically removing handwriting on the writing board body is arranged on the left side of the writing board body. A thermocouple capable of achieving heating and refrigeration and an electric heating and refrigeration piece are arranged on the other side, matched with the electroluminescence sheet in an inserted mode, of the second body. According to the electroluminescence sheet and the luminous writing board using the electroluminescence sheet, the handwriting on the writing board body can be automatically removed; and heating and refrigerating functions are achieved so that hands can be warmed in winter and can be cooled in summer.

Description

technical field [0001] The invention relates to the technical field of writing boards, in particular to an electroluminescent sheet and a light-emitting writing board using the electroluminescent sheet. Background technique [0002] Luminous writing board is a writing board that glows when turned on. It needs to be used with a (water-based) highlighter. The color of the highlighter is the color of the written word. The writing board is equipped with 4 lighting modes. One is fully opened, that is, the entire writing board is illuminated; the second is half-opened, that is, the entire writing board is illuminated once every 2 seconds; the third is left and right circular partition scanning, that is, the layout is divided into 5 equal areas, starting from the left After lighting up for the same time from right to left, and then lighting up from right to left for the same time; the fourth is right-to-left circular partition scanning, that is, each area emits light in turn, and t...

Problems solved by technology

[0003] However, after writing on the writing board, it needs to be wiped off within 7 days, otherwise it will be difficult to wipe off after the time is exceeded, and because of the cold weather in winter, you will feel inconvenient when using the writing board with gloves on, and it is hot in summer. Sweat may appear in the palm of the hand when holding the tablet, which may cause inconvenience when using it
