Abstract
The invention discloses an electronic whiteboard using a capacitive touch screen. The electronic whiteboard comprises a computer, a projector, a controller and an interactive whiteboard. The interactive whiteboard comprises a substrate and a capacitive touch screen, the capacitive touch screen is mounted on the substrate, the interactive whiteboard is electrically connected with the computer through the controller, and the computer is electrically connected with the camera. The electronic whiteboard is operated by current induction of human bodies without an interactive pen, and is convenient to operate, defined in image, high in sensitivity and long in service life.
Description
Technical field
The present invention relates to a kind of electronic whiteboard, particularly a kind of electronic whiteboard that uses capacitance touch screen.
Background technology
Electronic whiteboard is the new high-tech product that has compiled multiple high-tech means research and development such as most advanced and sophisticated electronic technology, software engineering as a kind of emerging product, and it can realize with no paper office and teaching by being used with computing machine and projector.The application advantage of electronic whiteboard is man-machine interactive, and Faculty and Students can directly operate document and software with special pens on blank, even must not use the keyboard just can be at the screen mark of writing and paint, and is very convenient and directly perceived.
Electronic whiteboard is developed by common blank, and the electronic whiteboard of Chu Xianing is duplicating type electronic whiteboard the earliest, along with the development of technology and the needs in market, interactively electronic whiteboard occurred.
The interactive blank of present interactive electric whiteboard is pressure sensitivity technology, infrared technology, ultrasonic technology and electromagnetic induction technology substantially all, the interactive blank of these structures easily goes wrong, and safeguard high, life cycle is shorter, have following shortcoming: (1) pressure sensitivity technology: it is painstaking to write, and pressure can't show writing inadequately; Reaction velocity is slow; Supporting pen can not be realized right button function, inconvenient operation; Some function needs bimanualness; The hardware rapid wear.(2) infrared technology: resolution is low, and the response time is long, and a little less than the signal, the blank flatness requires high, the environmental requirement height, and instability, the hardware rapid wear because infrared transmitting tube is aging, causes this kind technology electronic whiteboard life-span low.(3) ultrasonic technology: need special ultrasound wave emission pen, and volume is bigger, is not suitable for meticulous writing; Service range is restricted; Need in the use near operation.(4) electromagnetic induction technology: must use special pens just can write, can not do touch operation, inconvenient teaching management, reaction velocity is fast inadequately, and person's handwriting just occurred after the past of namely writing, and was afraid of to scratch, in case the middle scuffing entire plate that occurs just may not have been used, in addition, be difficult to realize the space of a whole page making of overlarge area, and radiation is bigger.
Summary of the invention
The technical problem to be solved in the present invention is the defective that overcomes prior art, and a kind of electronic whiteboard that uses capacitance touch screen is provided, and this electronic whiteboard does not need induction pen, and is highly sensitive, and can realize multiconductor operation, long service life.
For solving the problems of the technologies described above, the invention provides a kind of electronic whiteboard that uses capacitance touch screen, comprise computing machine, projector, controller and interactive blank, interactive blank comprises substrate and capacitance touch screen, capacitance touch screen is on the upper strata, and substrate is in lower floor, and capacitance touch screen is installed on the substrate, interactive blank is electrically connected with computing machine by controller, and computing machine is electrically connected with camera.
Electronic whiteboard of the present invention utilizes the electric current induction of human body to carry out work, does not need to use induction pen, can realize the multiconductor operation, and is easy to operate, and clear picture, highly sensitive; Owing to do not need the working pressure induction, the surface is difficult for scratching long service life; Do not have big electric current and pass through, plate body is difficult for heating.Just can respond to owing to touch, easy to use, and the contacting almost less than wearing and tearing of finger and touch screen, stable performance reaches 30 years through mechanical test serviceable life; Environment for use requires lower; No service range restriction; Other several technology are radiationless substantially relatively.
Substrate mainly plays a part to support capacitance touch screen, can be glass plate, sheet metal, plastic plate, aluminium-plastic panel or plank etc.
In order to reach office or teaching purpose better, the size of capacitance touch screen is at least 1 m
2, so more can make things convenient for the participant to observe screen and go up content displayed.
Described capacitance touch screen EVA(ethylene-vinyl acetate copolymer), PVB(polyvinyl butyral) or glue etc. be glued on the substrate.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of electronic whiteboard that uses capacitance touch screen, comprise computing machine 1, projector 2, controller 3 and interactive blank 4, interactive blank 4 comprises substrate 41 and capacitance touch screen 42, capacitance touch screen 42 can be the mobile phone capacitance touch screen, substrate 41 mainly works to support capacitance touch screen 42, so substrate 41 can be plastic plate, sheet metal, aluminium-plastic panel or plank etc., capacitance touch screen 42 passes through EVA, PVB or glue etc. are glued on the substrate 41, interactive blank 4 is by the RS-485 line, the parallel port, serial ports, USB interface or netting twine are electrically connected with controller 3, controller 3 is electrically connected with computing machine 1 by the USB line, computing machine 1 is electrically connected with camera 2 by VGA line or HDMI line, and camera 2 can be the image of computing machine, audio frequency or literal etc. project on the capacitance touch screen 42.
Need to prove that above-mentioned is a kind of embodiment of the present invention, the simple deformation of doing on this basis can also be connected with utility appliance such as sound equipment, printers as computing machine, also should be considered as protection scope of the present invention.
