Abstract

The invention discloses a typeface-scalable writing board. The type-face scalable writing board comprises a back plate provided with a groove. The groove is filled with electric conduction liquid. A dielectric elastomer film is arranged on the groove edge of the groove in a tightened manner. The face, facing the groove, of the dielectric elastomer film is in contact with the electric conduction liquid, and the other face of the dielectric elastomer film is coated with a nano wire electrode. The electric conduction liquid and the nano wire electrode are connected with a power source. Corresponding dynamic effects can be generated on characters or pictures on the writing board by changing the driving voltage and the changing frequency, and therefore the purpose of highlighting display is achieved.

Description

technical field [0001] The invention relates to the field of writing or drawing utensils, in particular to a writing board with scalable fonts. Background technique [0002] In daily life, the writing board has become very popular. People use the writing board to express the knowledge to be learned or shared on the board during study, class, and training, so as to facilitate communication. With the popularity of applications, writing boards have penetrated into every aspect of our daily life, and can be seen in schools, offices, shopping malls and other occasions. [0003] After a long period of development, in daily life, the writing board has various forms. The most common are black and white writing with chalk, and writing whiteboards with whiteboard markers. [0004] The invention of the magnetic writing board has a history of 20 or 30 years. It is widely used because of its less pollution, convenient use, low price and reusability. The traditional magnetic writing bo...
