Abstract

The invention discloses a flexible light-emitting panel and a handwriting board, and relates to the technical field of printed electronics. The flexible light-emitting panel comprises a substrate layer, a conductive layer and a light-emitting layer. The substrate layer is made of a flexible material. The conductive layer is arranged on the substrate layer. The conductive layer comprises a positiveelectrode strip and a negative electrode strip which are alternately arranged. The light-emitting layer is made of an electroluminescent material. The light-emitting layer is arranged on the conductive layer and fills the gap between the positive electrode strip and the negative electrode strip. The thickness of the portion, protruding out of the conductive layer, of the light-emitting layer is smaller than the distance between the adjacent positive and negative electrode strips. In the flexible light-emitting panel, by forming conductive writing traces on the light-emitting layer, transitionof electrons of the light-emitting layer can be excited, so that a writing part emits light, and the selection range of writing pens is wide; and the flexible light-emitting panel can be freely curled and carried around.

Description

technical field [0001] The invention relates to printed electronic technology, in particular to a flexible luminescent panel and a handwriting board. Background technique [0002] At present, there are two mainstream handwriting boards on the market. One is to emit light through LED, and the fluorescent powder absorbs the LED light to emit light after writing with a highlighter. Because this type of writing board is made of LED, the entire panel is hard. The sheet material cannot be flexibly folded or curled. At the same time, the writing pen of the tablet can only be a highlighter, which is mainly used as a signboard at night, and the use function is also limited due to the characteristics of the product. The other is a liquid crystal light-emitting panel, which uses a layer of liquid crystal film to display and write, but this liquid crystal film needs a hard flat plate as a substrate to ensure that the thickness of the liquid crystal film is consistent without external f...
