Description

Technical Field

[0001] The present application relates to the technical field of data display, and in particular to a data display device. Background Art

[0002] Data presentation refers to the presentation of information to be presented through equipment, some of which are through multimedia, electronic display screens, and some through traditional display boards. Generally, when presenting data, the speaker will perform some calculations, annotations, and other actions, and some will interact with the audience, such as the teacher presents the data information of the question, and the students need to solve the problem; if multimedia is used, it can only be done in a fixed multimedia classroom, which is not easy to achieve when resources are tight. With the development of technology, more and more classrooms have introduced multimedia to meet the needs of classes, but for after-class, when parents teach their children, they cannot use multimedia; if a display board is used, the teacher or parent needs to copy the question, which wastes time and reduces the efficiency of teaching.

[0003] In the prior art, improvements to data display devices are mostly in terms of adjustable angles and heights. For example, in prior art 1, a data display device with application number CN201920757292.1 provides a technical solution, including a bearing column, a base, a foot support and a shell, both ends of the bottom of the base are welded with foot supports, and both ends of the top of the base are welded with bearing columns, an adjustment rod is installed at the top of the bearing column, and a mounting rod is provided at the top of the adjustment rod, a main body is installed on one side of the mounting rod, a shell is hingedly connected to the side of the main body away from the adjustment rod through a connecting arm, and an electric telescopic rod is installed between the shell and the main body, and a display screen is installed on the side of the shell away from the main body; the application is equipped with a main body, a connecting arm, an electric telescopic rod, a shell and a display screen, so that the device can change the angle between the shell and the main body by starting the electric telescopic rod, thereby realizing the adjustment of the display angle of the display screen, thereby enhancing the practicality of the device; the angle of the display screen can be adjusted in the application, but additional auxiliary devices are required to realize calculation, annotation, interaction and other actions when performing data display.

[0004] Prior art 2: A data display device with application number CN202220826848.X provides a technical solution, including a frame body with a middle display panel, two side display panels movably arranged on the frame body, and at least one vertical display panel that can be hidden in the frame body; wherein the side display panel is arranged on the front side of the middle display panel, and the vertical display panel is arranged on the rear side of the middle display panel; the two side display panels move toward or away from each other, so as to be stored in the frame body and cover the middle display panel when approaching each other, or to be hidden in the frame body when moving away from each other. The rear extension is configured outside the frame body and directly exposes the middle display board; the vertical display board can freely switch between a first position overlapping with the middle display board and a second position extending outside the frame body in a staggered manner to facilitate further display expansion; thus, the data display device has a simple structure and stable operation, so that each data display board has functional attributes and practicality. The application can realize a large-scale display of data through the cooperation of each display board, but in the application, all data need to be manually copied, which reduces work efficiency and is prone to copying errors when the writing volume is large.

[0005] The applicant conducted a detailed search of the prior art and found no technical solution for the combination of electronic display and panel display. Therefore, it is necessary to provide a new technical solution to solve the above technical problems. Utility Model Content
