Fig. 1 shows a configuration of a display system of an electronic blackboard according to an embodiment of the present invention, and for convenience of explanation, only a portion related to the embodiment of the present invention is shown.
Referring to fig. 1, the display system of the electronic blackboard includes an electronic blackboard 1 and a sensing pen 2. The electronic blackboard 1 is provided with a pressure sensor, and the pressure sensor is used for sensing the contact of the induction pen 2.

The electronic blackboard 1 changes the display color of the current written content according to the acting force, thereby achieving the effect of marking.
Fig. 2 shows an implementation flow of the display method of the electronic blackboard provided by the embodiment of the invention.
Referring to fig. 2, the display method of the electronic blackboard includes:
in step S201, a corresponding relationship between the force of the sensing pen and the display color is set.
In the embodiment of the invention, the acting force of the induction pen refers to the force of the user acting on the induction pen. The display color refers to a color displayed on the electronic blackboard. Here, the sensing pen has a certain acting force range, and the display color corresponding to each acting force in the acting force range is established in advance in the embodiment of the present invention, so that the electronic blackboard can adjust the display color of the written content according to the acting force of the user on the sensing pen.

In step S302, display colors corresponding to each of the force sections are set, wherein one of the force sections corresponds to one of the display colors, and the display colors corresponding to different force sections are different from each other.
Here, in order to increase the visual difference between different writing contents, the embodiment of the present invention divides the force range of the sensing pen into a plurality of force sections, and sets a corresponding display color for each force section. Wherein, an acting force interval corresponds to a display color, and the color difference between the display colors of different acting force intervals should be more obvious. Exemplarily, assuming that the acting force range of the induction pen is 1 to 5, the acting force range can be divided into four acting force intervals, and when the acting force is greater than or equal to 1 and less than 2, the corresponding display color is 1; when the acting force is more than or equal to 2 and less than 3, the corresponding display color is 3; when the acting force is more than or equal to 3 and less than 4, the corresponding display color is 3; when the acting force is more than or equal to 4 and less than 5, the corresponding display color is 4. The display colors 1, 2, 3 and 4 should be selected from different colors and have a significant color difference from each other, so that the user can quickly recognize the label content on the electronic blackboard.

Referring to fig. 4, the step S203 includes:
in step S401, a contact trajectory of the sensing pen on the electronic blackboard is acquired, and writing content is displayed on the electronic blackboard according to the contact trajectory.
In step S402, a display color corresponding to the applied force is obtained according to the correspondence, and the color of the written content is adjusted to the display color.
The electronic blackboard acquires contact information of the induction pen based on a pressure sensor of the electronic blackboard to obtain a contact track of the induction pen, and then matches corresponding writing content according to the contact track and displays the writing content. Meanwhile, the electronic blackboard searches for the corresponding relation preset in the step S201 according to the received user acting force to obtain an acting force interval to which the acting force belongs, and adjusts the color of the current written content to the display color by taking the display color corresponding to the acting force interval as the display color of the acting force; therefore, the color of the written content is automatically changed according to the acting force of the user in the process of writing on the blackboard by the electronic blackboard, the written content is marked, marking operation of line drawing or circle drawing of the user is avoided, the existing marking mode is simplified, and the experience of the user is effectively improved.
In summary, in the embodiment of the present invention, the corresponding relationship between the acting force of the sensing pen and the display color is set; when the induction pen is detected to write on the electronic blackboard, acquiring the acting force of a user on the induction pen; then, according to the acting force, the color of the current written content on the electronic blackboard is adjusted to be a display color corresponding to the acting force; therefore, the color of the written content on the electronic blackboard can be changed according to the acting force of the user, so that the user can synchronously mark the content on the electronic blackboard through different writing forces when writing on the electronic blackboard; the embodiment of the invention changes the usual labeling mode and effectively simplifies the labeling operation of the user; also make the student can distinguish key content fast according to the colour of writing the content, richened the teaching mode.
