Description
Technical field
The utility model relates to a kind of parts of touch control display apparatus, relates to a kind of parts that utilize infrared ray to realize the touch control display apparatus of touch control operation especially.
Background technology
Common infrared touch control display apparatus is mainly by tabular display unit (comprising LCDs and blank) be centered around the housing formation that four block weldings around the tabular display unit have the printed circuit board (PCB) (being also referred to as printed-wiring board (PWB), printed circuit board, printed board, PCB or PWB) and the fixed printed circuit board of infrared emission tube/infrared receiving tube.One row's infrared emission tube of next-door neighbour's tabular display unit front end face on fore-and-aft direction is installed on the frame plate structure spare of a side that is positioned at left and right sides of the housing of this device, and corresponding one by one another row's infrared receiving tube that next-door neighbour's tabular display unit front end face on fore-and-aft direction is installed on the frame plate structure spare of the opposite side that is positioned at left and right sides of housing, one row's infrared emission tube of next-door neighbour's tabular display unit front end face on fore-and-aft direction is installed on the frame plate structure spare of a side that is positioned at upper and lower sides of housing, and corresponding one by one another row's infrared receiving tube that next-door neighbour's tabular display unit front end face on fore-and-aft direction is installed on the frame plate structure spare of the opposite side that is positioned at upper and lower sides of housing, thereby make this device form an infrared ray grating detection network in the front side of tabular display unit in use.When the operator a bit contacts with certain of hand or form of a stroke or a combination of strokes object and tabular display unit, just can block two infrared rays anyhow through this position, make infrared receiving tube can not receive the infrared ray of corresponding infrared transmitting tube emission, the control system of controlling this infrared touch control display apparatus just can calculate touch point position immediately, again according to moving corresponding program in the implication of the shown icon in this position, perhaps show finger or form of a stroke or a combination of strokes object walking route at once and carry out corresponding literal identification and storage or corresponding graphics memory, thereby realize touch control operation.
But the printed circuit board (PCB) in the infrared touch control display apparatus of this structure is provided with according to the mode that is parallel to each other with the tabular display unit, thereby has following shortcoming: the first, make that the housing size is bigger, and seem very thick and heavy.Second, infrared/receiving tube 3 need carry out after the clubfoot operation welded and installed to printed-wiring board (PWB) again, or first welded and installed is to printed circuit board (PCB), carry out clubfoot again, complex procedures not only, increased manufacturing cost, and infrared/receiving tube may exert an influence behind clubfoot to its life-span and stability.The 3rd, need assist fixedly infrared/receiving tube by the plastics guide frame is installed, increased manufacturing cost.Chinese patent literature CN201066498Y(application number 200720052423.3) and CN201044097Y(application number 200720051069.2) promptly be the patented claim that belongs to said structure.
As said structure being improved the imagination that is proposed, Chinese patent literature CN2731587Y(application number 200420066267.2) disclose a kind of circuit board and vertically be around in infrared touch panel around the display screen.The infrared touch panel of introducing this structure according to the document can be done the housing size very little, but, in the embodiment of the document, only having enumerated the circuit board that is welded with infrared emission component and receiving element is the vertical display screen technical characterictic all around that is around in, can only draw described circuit board by its accompanying drawing is vertically to be attached to display screen conclusion all around, this structure is for abnormally dangerous the fixedlying connected of display screen and housing, its unreasonable structure.In addition, in claims and summary of the invention part of the document, proposed this infrared touch panel and also comprised the structural member that is used for fixing circuit board.But whole document is all less than disclosing whether this structural member has relation with display screen and be the technical characterictic of which kind of relation, thereby this imagination with structural member also lacks essential features, makes those skilled in the art to implement.Simultaneously, the instructions that can draw the document by above-mentioned analysis can not be supported the conclusion of claims.
