In order to solve interactive liquid crystal electronic whiteboard and conventional white board separately causes awkward problem, in some practices, user utilizes the glass be fixed on liquid crystal interactive electric whiteboard to realize the function of common blank.But, black or dark color itself is generally due to liquid crystal flat-panel, be difficult to identify written contents, as passed through to start PC or Android main frame, by liquid crystal display background for being adjusted to white or light color, form a backlight so that user is seeing write content more at a distance clearly, the defect of this way is that PC or Android host-initiated needs certain hour (being generally 2-5 minute), the start-up time that needed wait time is longer.
In addition, number of patent application be 200910251635.8 patent a kind of integrated large screen flat plate display multimedia combined type blackboard is disclosed, by translation open box-like blackboard, large-sized FPD multimedia play system, blackboard frame type loudspeaker Wireless sound amplifying system and band pointer function photoelectric wireless mouse four part form.Adopt flat-panel monitor and normal blackboard array mode to carry out exchange to give lessons.What this combined blackboard can realize the teaching of under bright room environmental multimedia and normal blackboard traditional instruction synchronously carries out effect.Its structure of this combination is more complicated, also will with blackboard with the use of, its application places is very limited, is generally only suitable for using in classroom.
Utility model content
Can not compatible one in order to overcome existing interactive liquid crystal electronic whiteboard and common blank, cause and use inconvenience, and the problem that PC (or Android) host-initiated stand-by time is long, fundamental purpose of the present utility model is to provide a kind of Combined integrated interactive liquid crystal electronic whiteboard, not only structure is simple for it, interactive liquid crystal electronic whiteboard and common blank can be combined, can unrestricted choice electronic whiteboard or common white boarding according to appling courseware person, also improve display as a setting fluorescence time response speed.
Above-mentioned purpose is achieved by the following technical solution:
According to an aspect of the present utility model, the integrated interactive liquid crystal electronic whiteboard that the utility model provides, have employed technical scheme: comprising: housing, flat-panel monitor, in order to drive and to control the display main board of display, touch-screen, and the computer main board to be electrically connected with touch-screen, touch-screen is arranged on flat-panel monitor front portion, computer main board is electrically connected with display main board, also comprise a fluorescence tablet switching device shifter, this fluorescence tablet switching device shifter is electrically connected with display main board, the fluorescence mode that the applicable human eye set in order to the backlight being converted to by the light efficiency of backlight waking display under display powered sleep up accepts.
Owing to adopting the integrated interactive liquid crystal electronic whiteboard of above technical scheme, on same loom, user can according to courseware content, unrestricted choice electronic whiteboard or common white boarding is selected by switching fluorescence tablet switching device shifter, avoid, on interactive liquid crystal electronic whiteboard side, the waste of common blank and the inconvenience of use are installed again, because backlight is provided with the fluorescence mode application program of applicable human eye acceptance, as long as start fluorescence tablet switch key, program is activated in a short period of time and is lit, also overcome by the long Holding Problem of PC (or Android) host-initiated stand-by time.
Above technical scheme is further improved by following measures:
In some embodiments; touch-screen is adopted infrared touch panel; this infrared touch panel also comprises one block of tempered glass mated with flat-panel monitor size; according to the characteristic of infrared touch panel; more easily produce the anti-riot touch one-piece machine of oversize; when using common white boarding, tempered glass can be write as clipboard, better protecting LCD screen.
In some embodiments, in order to ensure, as while brightness during common blank, not stimulate eyes, fluorescence mode is set to the shallow white of applicable human eye acceptance or greyish white coloured light.
In some embodiments, conveniently the operation of fluorescence tablet switching device shifter, switch key is arranged on housing.
In some embodiments, flat-panel monitor is LED liquid crystal display.
This integrated interactive liquid crystal electronic whiteboard realizes the method for common written white boarding, comprises following step:
A. confirm that all-in-one is in powered sleep, main frame is in off-mode;
B. start fluorescence tablet switching device shifter, activation signal instruction sends to display main board;
C. display main board receives instruction, interrupts dormancy, starts wake up procedure;
D. the light efficiency in display backlight source is converted to the white of applicable human eye acceptance or linen backlight by program, is modeled to common fluorescent blank, cuts off the touch work of touch-screen simultaneously.
In some embodiments, in order to reduce the stand-by period, the light efficiency in display backlight source is converted to white or the linen backlight program execution response time is about 3-5S.
