Description
Technical field
The present invention relates to a kind of touch module and component, particularly relate to a kind of optical touch module and component thereof.
Background technology
Optical touch control because the lifting of LED quality and progressing greatly of processing procedure, so have high light transmittance, respond to the touch-control of any material and be applicable to large-sized advantage, is therefore widely applied over the display at present.Optical touch display principle utilizes to arrange corresponding LED emitter and the optical touch module of receiver at the surfaces opposite sides of display, form densely covered infrared ray grid by the X-axis of infrared LEDs all around on display screens surface and Y-axis, after opaque article blocking light wherein, naturally just orient X-axis and Y-axis.Infrared LEDs is respectively independent and single, as long as do the object of resolving and can accomplish to locate to the position of blocking, finally via the computing of control circuit, signal is sent to PC again, again via the position that screen display translation was touched just now, or perform other signal manipulation utilization again via other softwares.Infrared touch control panel adopts the mode of blocking LED infra-red signal to operate, so can touch ground just have signal triggering, has highly sensitive advantage.
The schematic diagram of infrared touch control component as 1A is, the framework that this infrared touch control component 10 is made up of four infrared touch control modules 11, two opposite sides of framework are respectively equipped with two groups of corresponding LED emitter 12 and LED receiver 13, and wherein each LED emitter 12 corresponds to a LED receiver 13.
Continuous as Figure 1B be the composition X-X diagrammatic cross-section of 1A infrared touch control module, the section getting the side of this infrared touch control component 10 illustrates the composition (as Figure 1A) of an infrared touch control module 11, though get LED emitter in this figure as explanation, but LED receiver is identical composition structure.Infrared touch control circuit module comprises a control circuit board 111 and which is provided with a LED circuit board 112 as shown in the figure, aforementioned LED emitter 12 is arranged in this LED circuit board 112, and wherein control circuit board 111 is provided with control IC in order to control the LED emitter 12 of LED circuit board 112.Welding manner is utilized to be combined between control circuit board 111 with LED circuit board 112, so between control circuit board 111 and the obverse predeterminated position of LED circuit board 112, retain the multiple first pad 15 connection control circuit board 111 and LED circuit board 112 that solder formed, and the signal of two circuit boards is transmitted by these first pads 15.Usually the signal transmission between circuit board is considered so the first pad 15 all can more than more than one.Generally speaking, solder system is made up of the metal that fusing point is lower, such as tin etc.
If Fig. 1 C is the schematic diagram that four infrared touch control modules 11 connect into framework.Utilize four L-type web joints 16 as four corners as shown in the figure, each L-type web joint 16 is connected with the infrared touch control module 11 of framework both sides, namely each infrared touch control module 11 is connected between two L-type web joints 16, and four infrared touch control modules 11 form framework by these four L-type web joints 16.
Moreover 1D is the schematic diagram of the Y-Y section of Fig. 1 C.Aforementioned four L-type web joints 16 are arranged on the below of this control circuit board 111 as shown in the figure, then the mode of welding is utilized to be combined with this control circuit board 111, leave multiple second pads 17 that solder is formed between the predeterminated position of control circuit board 111 and L-type web joint 16, by these second pads 17, the signal of four infrared touch control modules 11 is connected and transmits.
Due to each L-type web joint 16 need with control circuit board 111 solder joint of the infrared touch control module 11 of both sides, and multiple first pad 15 and multiple second pad 17 are usually more than more than one, so in the process of composition framework, the weld job time is long, and quality is wayward.Moreover the corresponding surface of control circuit board 111 and LED circuit board 112, namely two circuit board overlapping regions, cannot be used to put element, so produce invalid in infrared touch control component 10, be unfavorable for circuit design, the use of also unfavorable heavy industry maintenance.
Therefore, how solving foregoing problems, is the target that those skilled in the art will actively solve.
