Description

A kind of infrared touch panel
Technical field
The utility model relates to a kind of touch-screen, relates in particular to a kind of infrared touch panel.
Background technology
The infrared touch panel technology is high with its stability, adaptability is strong, is widely used.
Infrared touch panel as shown in Figure 1, comprise two groups of infrared transmitting tubes, two groups of infrared receiving tubes and touch surveyed area, wherein one group of infrared transmitting tube and one group of infrared receiving tube are laterally installed, one group of infrared transmitting tube and one group of infrared receiving tube are vertically installed, when the operation thing enters the touch surveyed area, laterally infrared transmitting tube of installing and infrared receiving tube are obtained the horizontal ordinate of operation thing position, vertically infrared transmitting tube of installing and infrared receiving tube are obtained the ordinate of operation thing position, come operation thing location with this; This two groups of infrared transmitting tubes of scheme palpus and infrared receiving tube and driving circuit, cost is higher.
As shown in Figure 2, patent No. CN201548935 discloses a kind of infrared touch panel, comprises one group of infrared transmitting tube, one group of infrared receiving tube and touches surveyed area, and infrared transmitting tube is installed on respectively with infrared receiving tube and touches the relative both sides of surveyed area; This scheme only must one group infrared transmitting tube and infrared receiving tube, cost is lower, but precision is not high, easily by ambient light effects, produces maloperation.
The utility model content
The utility model provides a kind of with low cost, the infrared touch panel that performance accuracy is high for solving the prior art problem.
The technical solution of the utility model is: a kind of infrared touch panel, comprise the infrared tube row who forms by infrared tube and touch surveyed area, described infrared tube comprises infrared transmitting tube and infrared receiving tube, it is characterized in that: described infrared tube row is installed on the relative both sides of described touch surveyed area, and the infrared tube of at least one side row is staggered by infrared transmitting tube and infrared receiving tube and forms.
When comprising infrared ray in the surround lighting, these infrared rays often have certain directivity, the infrared receiving tube that is in a side is as in the range of exposures that just in time is in surround lighting the time, infrared receiving tube can receive the infrared ray in the surround lighting, at this moment, infrared ray in the surround lighting can produce CR Critical interference to the infrared ray that infrared transmitting tube is launched, and causes the maloperation of touch-screen; When infrared power valve and infrared receiving tube were staggered, the infrared receiver tube that is in the surround lighting irradiation scope was subjected to the interference of surround lighting, but the infrared receiver tube that is in opposite side can not be interfered, and still can make accurate location to the operation thing; Infrared receiving tube after being staggered not only can receive the stronger infrared ray that the opposite side infrared emission tube sends, can also receive that the same side infrared emission tube sends and through the more weak infrared ray of operation thing reflected back, by to receiving the judgement of these two kinds of infra-red intensities, distinguish the ultrared source that receives, and, can more accurate the operation thing be positioned by calculating; Simultaneously, by direct projection and reflected infrared are calculated, can position being in a plurality of different operation thing that touches in the surveyed area.
As preferably, described infrared transmitting tube LED power valve, emission angle is the 90-160 degree.Emission angle is big, and then receivable infrared receiver tube is many, and operation article coordinate data are abundant, and it is more accurate to locate.
As preferably, described being staggered to alternately.Infrared transmitting tube and infrared receiving tube make whole touch surveyed area operate thing positioning resolution and bearing accuracy homogeneous alternately, and it is more stable to touch detection; Infrared transmitting tube and infrared receiving tube arrangement mode are single, even, make that the driving circuit be in the infrared transmitting tube that touches the surveyed area both sides and infrared receiving tube is identical, save the circuit board cost.
As preferably, described be staggered into: two or more infrared transmitting tubes are formed the emission groups, and two or more infrared receiving tubes are formed the reception groups, and described emission group and reception group are alternately.Increase or reduce the arranging density of infrared receiving tube as required in the different piece that touches surveyed area, make the different piece that touches surveyed area have different operation thing positioning resolution and bearing accuracy, so that touch-screen is suitable for multiple different occasion; Strengthen the arranging density of infrared reception at the edge that touches surveyed area, make the edge that touches surveyed area have higher positioning resolution and bearing accuracy, solved the relatively poor problem of most of touch-screen edge effects.
As preferably, described infrared touch panel also is provided with rectangular framework, and described infrared emission tube and infrared receiving tube are installed on two longer sides of framework.
As preferably, described infrared touch panel also is provided with rectangular framework, and described infrared emission tube and infrared receiving tube are installed in two of framework than on the minor face.
As preferably, infrared tube row part is in and touches outside the surveyed area.Guarantee that the optional position all can be located in touching surveyed area.
In sum, the utlity model has following advantage:
1, infrared transmitting tube and infrared receiving tube are staggered, and are not subject to ambient light interference, accurate positioning, precision height;
2, infrared receiving tube not only can receive the stronger infrared ray that the opposite side infrared emission tube sends, and can also receive that the same side infrared emission tube sends and through the more weak infrared ray of operation thing reflected back, bearing accuracy height;
3, the driving circuit that transmits and receives of infrared touch panel adopts same design, saves cost.
