Embodiment Construction

[0029] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0030] refer to Figures 1 to 2 , figure 1 It is a schematic flowchart of the display method of the digital push-pull board of the present invention; figure 2 It is a schematic diagram of the structure of the digital push-pull board of the present invention. A method for displaying a digital push-pull board provided by this embodiment includes the following steps:

[0031] Step S10, controlling the display interface to display two display layers.

[0032] The two display layers are the first display layer and the second display layer, respectively. Wherein, the first display layer is always arranged on the top layer, and the second display layer is arranged on the bottom layer. When there is an overlapping area between the first display layer and the second display layer, the current display interface disp...

Abstract

The invention discloses a display method of a digital push-pull board and the digital push-pull board. The display method of the digital push-pull board includes the steps that a display interface is controlled to display at least two display layers, the display layers selected by a user are identified, and whether an operating instruction input by the user is a commonly-used operating instruction suitable for all the display layers is judged. In the classroom teaching process of the user, outline content and explanation content can be arranged on different display layers, the user inputs the operating instruction on the display layers, and if the input operating instruction is the commonly-used operating instruction, corresponding operation can be carried out on the display layers selected by the user; if the operating instruction input by the user is a specific operating instruction, corresponding operation can be carried out on the display layer corresponding to the specific operating instruction. The phenomenon that display of the outline content is affected when the user operates the explanation display layer is effectively avoided, and therefore the classroom teaching adaptability of the digital push-pull board is improved.

Description

technical field [0001] The invention relates to the field of digital writing boards, in particular to a display method of a digital push-pull board and a digital push-pull board. Background technique [0002] All-in-one computers currently on the market generally provide the function of a writing board. When the all-in-one computer switches to the writing board, the entire screen changes to the color of the writing board, similar to the blackboard used in the classroom in the real scene. At this time, the user can write, erase and other operations on the writing board, and provide functions such as all erase and recovery. [0003] In class, users often write an outline on one side of the blackboard, and expand and explain the outline on the other side of the blackboard. The content of the outline will be retained for the entire lesson, and the content of the lecture will be erased frequently to facilitate the content of the lecture after writing. When using the all-in-one...
