Embodiment Construction

[0013] see figure 1 The embodiment of the present invention provides an electronic writing board 100, which includes a base color board 10, an electrochromic board 20 arranged on the surface of the base color board 10, a touch screen 30 arranged on the surface of the electrochromic board 20, a driving circuit module 40 and user interface 50 .

[0014] The base color plate 10 is the base color display panel of the electronic writing board 100. When the electrochromic plate 20 is in a transparent state, the color of the base color plate 10 can be seen from the outside of the touch screen 30, which is displayed by the user. It can be seen that when a certain color is displayed in the partial area of ​​the electrochromic panel 20, the color of the base color panel 10 can set off the display color of the electrochromic panel 20, so that the display of the electrochromic panel 20 Colors are easy to distinguish. Generally, the color of the base color plate 10 is white or black.

Abstract

An electronic writing board comprises a background color board, an electrochromic board and a touch panel which are stacked in order. The background color board is used for displaying a background color. The electrochromic board is an electrochromic device. The touch panel is used for detecting a location of an object which contacts with the surface of the touch panel and transmitting a location message to the electrochromic device, so that the electrochromic device displays the preset color at the contact position of the touch panel.

Description

technical field [0001] The invention relates to the field of an electronic writing board. Background technique [0002] The traditional teaching blackboard uses chalk to write, and the dust of chalk is very easy to cause harm to human health. With the advancement of science and technology, the application of electronic writing board system is becoming more and more extensive, and there is a tendency to gradually replace traditional blackboards. A known electronic writing board system includes an electronic whiteboard, a computer and a projector. The electronic whiteboard has the property of electromagnetic induction, and the projector and the electronic whiteboard are connected to the computer. When in use, the electromagnetic induction pen is used to touch the surface of the electronic whiteboard and write. The electronic whiteboard senses the position of the electromagnetic induction pen and transmits it to the computer. The computer detects the movement track of the elec...
