Abstract
The utility model discloses an electronic whiteboard using a capacitive touch screen. The electronic whiteboard comprises a computer, a projector, a controller and an interaction whiteboard, wherein the interaction whiteboard comprises a baseplate and the capacitive touch screen installed on the baseplate, and is electrically connected to the computer by the controller, and the computer is electrically connected to a camera. The electronic whiteboard is operated by using the induction by current of a human body, and an induction pen is not needed, so convenience in operation is realized; in addition, a picture is clear, the sensitivity is high, and the service life is long.
Description
Technical field
The utility model relates to a kind of electronic whiteboard, particularly a kind of electronic whiteboard that uses capacitance touch screen.
Background technology
Electronic whiteboard, as a kind of emerging product, is the new high-tech product that has collected the multiple high-tech means research and development such as most advanced and sophisticated electronic technology, software engineering, and it can realize with no paper office and teaching by with computing machine and projector, being used in conjunction with.The application advantage of electronic whiteboard is man-machine interactive, and Faculty and Students can directly operate document and software by special pens on blank, even must not use the keyboard mark of just can writing on screen and paint, very convenient and directly perceived.
Electronic whiteboard is developed by common blank, and the electronic whiteboard occurred the earliest is duplicating type electronic whiteboard, along with the development of technology and the needs in market, interactively electronic whiteboard occurred.
The interactive white board of current interactive electric whiteboard is pressure sensitivity technology, infrared technology, ultrasonic technology and electromagnetic induction technology substantially all, the interactive white board 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 not; 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 signal, the blank flatness requires high, and environmental requirement is high, unstable, and 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 larger, is not suitable for meticulous writing; Service range is restricted; In use procedure, need 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 not, and after the past of namely writing, person's handwriting just occurred, was afraid of to scratch, in case entire plate middle, occurring scratching just may not use, in addition, be difficult to realize the space of a whole page making of overlarge area, and radiation is larger.
The utility model content
The technical problems to be solved in the utility model is the defect 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, highly sensitive, and can realize multiconductor operation, long service life.
For solving the problems of the technologies described above, the utility model provides a kind of electronic whiteboard that uses capacitance touch screen, comprise computing machine, projector, controller and interactive white board, interactive white board comprises substrate and capacitance touch screen, capacitance touch screen is on upper strata, and substrate is in lower floor, and capacitance touch screen is arranged on substrate, interactive white board is electrically connected to computing machine by controller, and computing machine is electrically connected to camera.
Electronic whiteboard of the present utility model utilizes the electric current induction of human body to carry out work, does not need to use induction pen, can realize the multiconductor operation, easy to operate, and clear picture, highly sensitive; Owing to not needing the working pressure induction, so surface is difficult for scuffing, long service life; Without large electric current, pass through, plate body is difficult for heating.Owing to touching, just can respond to, easy to use, and the contacting almost less than wearing and tearing of finger and touch screen, stable performance, reach 30 years through mechanical test serviceable life; Environment for use requires lower; Without service range, limit; Other several technology, substantially radiationless relatively.
Substrate mainly plays the Support Capacitor touch-screen, can be glass plate, sheet metal, plastic plate, aluminium-plastic panel or plank etc.
In order to reach better office or teaching purpose, the size of capacitance touch screen is at least 1 m
2, so more can facilitate the participant to observe the content of screen display.
Described capacitance touch screen EVA(ethylene-vinyl acetate copolymer), PVB(polyvinyl butyral) or glue etc. be glued on substrate.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment.
Embodiment
The utility model is described in further detail 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 white board 4, interactive white board 4 comprises substrate 41 and capacitance touch screen 42, capacitance touch screen 42 can be the mobile phone capacitance touch screen, substrate 41 mainly plays Support Capacitor 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 substrate 41, interactive white board 4 is by the RS-485 line, parallel port, serial ports, USB interface or netting twine are electrically connected to controller 3, controller 3 is electrically connected to computing machine 1 by the USB line, computing machine 1 is electrically connected to camera 2 by VGA line or HDMI line, camera 2 can be the image of computing machine, audio frequency or word etc. project on capacitance touch screen 42.
It should be noted that, above-mentioned is a kind of embodiment of the present utility model, and 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 domain of the present utility model.
