Abstract
Official abstract text for this publication.
An electrical writing board includes a bottom color plate, an electrochromic board, a touch panel, and a driving circuit module. The electrochromic board is covered on the bottom color plate, and includes a plurality of electrochromic units. The touch panel is covered on the electrochromic board, and outputs a touch signal when the touch panel is touched. The driving circuit module is electrically connected between the electrochromic board and the touch panel, and enables a part of the electrochromic units according to the touch signal to display a handwriting. The handwriting displaying on the electrochromic board is the same as a touch route sensed by the touch panel.
