Description
Technical field
The present invention relates to show the touch-control field, be meant a kind of display device that adopts touch especially.
Background technology
For operational convenience; When people replace mouse or keyboard work with touch-screen; We must be at first touch the touch-screen that be installed in the display front end with finger or other object, and system locatees selection information input touch-screen according to the icon of finger touch or menu position and forms by touching detection part and touch screen controller then; Touch detection part and be installed in the indicator screen front, be used to detect user touch location, send touch screen controller after the acceptance; And the main effect of touch screen controller is to receive touch information from touch point detection device, and converts it to contact coordinate, gives CPU again, and its can receive simultaneously the order that CPU sends and carry out.
Its advantage mainly is the function of supervisory keyboard and display screen to be gathered make display screen have the function of keyboard simultaneously for the digital product of above-mentioned application touch screen technology; The technology of this touch-screen not only can increase the area of display screen as much as possible in effective area, the appearance for whole digital product also has bigger lifting simultaneously.Technology through above-mentioned touch-screen can increase the size of display screen as much as possible under the prerequisite that does not increase the digital product overall volume, have digital product broadcast TV, the animated type video of touch-screen to become possibility thereby make through device.And with regard to the touch-screen that occurs on the market at present; The infrared type touch-screen occupies certain share; Be common infrared touch control display apparatus like the patent No. 200720052423.3 and the patent No. 200720051069.2 disclosed two kinds of patented products; It mainly comprises FPD parts (comprising LCDs), is centered around printed circuit board (PCB), housing that four block weldings all around of FPD parts have infrared emission tube and infrared receiver tube; Wherein, Said infrared emission tube and infrared receiver tube all are arranged on the display surface front side of said FPD parts, and the corresponding respectively left and right sides and the both sides up and down that are arranged on around the FPD parts of said infrared emission tube and infrared receiver tube, thereby make the display surface front side of FPD parts form an infrared ray grating detection network.When the user touches with finger or other object point that certain is some on the display surface of tabular display unit; Just can block two infrared rays through this position; Make infrared receiver tube can not receive the infrared ray that infrared emission tube corresponding with it launched; The control system of this infrared touch control display apparatus just can calculate the position of contact immediately, moves corresponding program according to the contact position corresponding command again, thereby realizes the touch control operation on the FPD parts.
Printed circuit board (PCB) in the infrared touch control display apparatus of aforesaid this structure is provided with according to the mode that is parallel to each other with the tabular display unit, exists a series of defective on its structure, concrete narration as follows:
First; Because being used to connect the printed circuit board (PCB) of infrared emission tube and infrared receiver tube is embedded around said FPD parts; And said printed circuit board (PCB) becomes same plane to be provided with the FPD parts, and when the housing of the explicit parts of the said flat board of encapsulation, said housing need encapsulate said printed circuit board (PCB); Therefore cause the housing size of said FPD parts also bigger accordingly, thereby make infrared touch control display apparatus seem very thick and heavy;
Second; Parallel with the FPD parts for the IR that makes infrared emission tube and infrared receiver tube launch and receive, infrared emission tube and infrared receiver tube 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; So not only complex procedures has increased manufacturing cost, and infrared emission tube and infrared receiver tube possibly exert an influence to its life-span and stability behind clubfoot.
Continuous development along with society; LCD is all to ultra-thin at present; Ultra narrow direction develops; Adopt frame according to traditional infrared touch panel, generally all need twenties mm wides, this mainly is subject to the arrangement width of the printed circuit board (PCB) that is used to connect above-mentioned infrared emission tube and infrared receiver tube.Thereby cause the technology that is difficult to use infrared touch-control on much ultra-thin, the ultra narrow display.More than be the existing in the specific implementation major technique defective of traditional infrared touch control display apparatus, be the present invention the subject matter that will research and solve.
