Projection screen with touch control function

Abstract

The invention discloses a projection screen with a touch control function, wherein a transparent or non-transparent conductive structure attaches to a projection screen to form the projection screen with the touch control function. Compared with a interactive whiteboard of the prior art, the projection screen comprises the advantages of simple structure, low manufacturing cost and the like. In addition, the projection screen is made from the flexible material, so that the protection screen can be furled by a screen holding shell, and the protection screen is easy to carry and move.

Description

technical field [0001] The invention relates to the technical field of interactive teaching, in particular to a projection screen with a touch function. Background technique [0002] In recent years, interactive electronic whiteboards have been widely used in conference discussions and teaching demonstrations. Among them, the Ministry of Education of Taiwan promoted the "Information Integration into Teaching ITC Program" in 2007, and fully subsidized hundreds of national middle schools and colleges in 15 counties and cities. The introduction of interactive electronic whiteboards in elementary schools allows teachers to improve teaching efficiency through interactive electronic whiteboards. [0003] see figure 1 , is a structure diagram of an existing interactive electronic whiteboard system. As shown in the first figure, the existing interactive electronic whiteboard system 1' includes: a computer host 11', a projection device 12', an interactive The electronic whiteboard ...

AI Technical Summary

Problems solved by technology

Its disadvantage is that it is necessary to use a specially-made electronic whiteboard to accurately position the position of the stylus on the electronic whiteboard; , I'm afraid it will be expensive

[0006] (2) Electromagnetic induction interactive electronic whiteboard: An induction coil must be installed in the electronic whiteboard, and an induction pen should be used together, so that the information exchange between the induction coil and the induction pen can accurately locate the induction The position of the pen on the electronic whiteboard; similarly, due to the complicated manufacturing process of the electromagnetic induction interactive electronic whiteboard, the application of large-size electronic whiteboards may be expensive

Therefore, from the above, it can be known that the manufacturing process of the pressure-sensitive interactive electronic whiteboard is not easy, and its cost is not cheap in the application of large-size electronic whiteboards.

[0008] (4) Regardless of any of the above-mentioned interactive electronic whiteboards 13', they are too bulky to be portable and mobile, forcing interactive teaching practitioners to purchase a set of interactive electronic whiteboards 13' in each teaching site, resulting in The investment cost of interactive teaching industry is too high

[0009] Through the above explanations about the functioning modes of different types of interactive electronic whiteboards 13', the applicant can know that, for the existing interactive electronic whiteboard system 1', its biggest shortcoming lies in the function of the interactive electronic whiteboard 13'. Complicated and expensive manufacturing process
