[0001] [0002] New description: [New technical field] This creation is related to the data transmission system, especially a data transmission system used between the touch screen and the projection screen. [Prior Art] At present, the combination of the optical touch screen and the stylus is very convenient and convenient in operation. Even users who are inputting the computer keyboard can easily complete various computer operations, and thus There are more and more products in the market and there is a tendency to become a trend. Moreover, the use of optical touch screens does not involve the misuse of the keyboard input, the embedding of dust and debris, and the fatigue of the buttons. The optical touch screen has many gains such as input and simultaneous display, but it still has the following problems in use: [0003] 1. Although the optical touch screen has the above convenience in use, it is used in a large teaching place. Or in the speech occasion, the optical touch screen used by the teacher or the speaker personally is obviously not matched in such large-scale occasions, and the information content displayed by the personal optical touch screen in large-scale occasions is often too small. The students or listeners underneath can't know the content of the speech and interact, let alone the desire of the class learners to seek knowledge. However, in order to overcome the above problems, in many teaching places or speech occasions, the operation of the speech and optical touch screens is often seen by two people, but the mode of use, the speaker and the computer operator It is necessary to cultivate an excellent tacit understanding. If this is not the case, it is easy for students to go to class or lectures, and the quality of teaching or speech is very good. Form No. A0101 Page 3 of 12 [0004] M429916 [0005] [0007] [0007] 2. At present, the optical touch screen has developed in the direction of a large screen, so that in many large teaching places or In the occasion of the speech, there are also settings for large-scale optical touch screens to display information content during teaching or speech, but in such occasions, the teacher or the speaker is using the stylus during the operation. It is necessary to travel frequently on both sides of the optical touch screen to enable the learner to know the content of the teaching or speech, and such teaching or speaking methods often cause the teacher or the speaker to speak after the whole lecture. Physical fatigue or tiredness and other physical discomfort. [New Content] This creation is to solve the inconvenience and trouble of using the touch screen, and to improve the practicality and convenience of the touch screen. Therefore, the present invention provides a data transmission system for a display device, comprising: a touch screen having at least one touch surface and a back surface opposite to the touch surface, wherein the back surface is provided with a plurality of position sensing Components, and a network interface is built into the position sensing elements. A stylus has a built-in signal transmission module, and the signal transmission module can receive signals from the network interface of the touch screen. [0009] A data processing device is embedded with a micro processing unit for receiving and recognizing a signal from the stylus and converting it into a data signal. A projection device is electrically connected to the data processing unit, whereby the signal outputted by the data processing unit can be projected onto a screen via the projection device. Form No. A0101 Page 4 of 12 [0010] [4291] The above screen is selected from one of a cloth body, a plate body, or a wall surface. [0012] The position sensing element is an integrated circuit, and the network interface is embedded in the integrated circuit. [0013] The network interface of the touch screen and the signal transmission module of the stylus have an IEEE 802. standard for receiving and transmitting RF signals. [0014] The network interface of the touch screen and the signal transmission module of the stylus have a Bluetooth standard to receive and transmit RF signals. [0015] The data processing device further includes a connection line electrically connected between the data processing device and the projection device. [0016] The above data processing device is a computer device. [0017] The micro processing unit has a signal receiving module and a frequency identification module. [0018] The specific features and effects of this creation are: [0019] 1. Convenience is good: when the creation is in use, the teacher or the speaker can be used by one person, and the whole class is not operated by the day. The resulting human error is not smooth, and the teacher or the speaker and the class can be more focused on the subject of the class without being disturbed, thereby enhancing the interactive and interesting nature of the class, and at the same time improving the teaching. Or the quality of speech and other benefits. [0020] 2. Practicality: This creation system can be used in various large and small occasions, without the inconvenience caused by using a personal touch screen, and without the physical discomfort caused by using a large touch screen. Sense, so the creation of the work has been the form number A0101 page 5 / a total of 12 pages M429916 service touch screen inconvenient and troublesome use, and practical. [Embodiment] [0021] Referring to the first figure and the second figure, the data transmission system of the display device of the present invention comprises: [0022] a screen (10) ' and the screen can be a cloth a body, a board, or a wall surface, etc., and in the embodiment, the screen (1〇) is a cloth body; [0023] a touch screen (20) 'having at least one touch a control surface (21) and a back surface (22) opposite to the touch surface (21), wherein the back surface (22) is provided with a plurality of position sensing elements (23), and the position sensing elements (23) are The network interface (231) is built in, and the sensing signals generated by each of the position sensing elements (23) are not the same, so the frequency of the signals sent by each network interface (231) is also different; in this embodiment, the position is The sensing component (23) is an integrated circuit 'and the network interface (231) is embedded in the integrated circuit; further, the network interface (231) has a communication protocol such as IEEE 802. standard or Bluetooth standard 'And both can receive and transmit signals, and in this embodiment, the network interface (231) is a basket Standard RF receiving and transmitting signals; Furthermore, the touch screen (2〇) system may be a digital capacitive touch screen or a monitor labor touch screen like one. [0024] As shown in the first and second figures, the stylus (30) is used to touch the touch surface (21) of the touch screen (20), and can be uplinked thereon. Writing or drawing, and corresponding to the touch screen (20) when the stylus (30) is written or drawn on the touch surface (21) of the touch screen (20) The position sensing component form number A0101 under the touch surface (21) is 6th/12th (23), and a plurality of different sensing signals are generated, and the sensing signals are sensed by the positions. The network interface (231) in the component (23) is transmitted to the stylus (30), and a signal transmission module (31) is built in the stylus (30), and the signal transmission module (31) Transmitting the sensing signals from the position sensing elements (23) to the data processing device (40); further, the communication protocol of the signal transmission module (31) and the touch screen (20) The communication protocol of the network interface (231) is the same.
