difference between capacitive touch and infrared touch

Features	INFRARED 6POINTS TOUCH		INFRARED 10POINTS TOUCH		CAPACITIVE TOUCH (All 10points)
principle	Infrared Touch: By infrared lines emission around, when object cut the infrared lines it will react, it‘s one kiod of no touch touch, fingers or other object intercept the infrared lines to give touch order,screen itselft have no touch function, need a frame,to replace or repair no need change screen,with high accuracy,but can react for any object touch.		Infrared Touch: By infrared lines emission around, when object cut the infrared lines it will react, it‘s one kiod of no touch touch, fingers or other object intercept the infrared lines to give touch order,screen itselft have no touch function, need a frame,to replace or repair no need change screen,with high accuracy,but can react for any object touch.		Capacitive touch:also called electrostatic touch screen,react by current sense of human body. It‘s one kind of 4 layers composite glass screen, the inner surface of the glass panel and the layers are coated with a layer of ITO, the outermost layer is a thin layer of silica glass protection layer, tnterlayer ITO coating as working face,four electrodes on four corners, the inner ITO is a shield to ensure good working environment.When the fingers touch the metal layer, due to human electric field, the user and touch screen surface is formed with a coupling capacitor,for high frequency current, capacitance is a direct conductor,so the fingers take away from the contact point of a small current. The current flows out of the electrodes on the four corners of the touch screen seperately, and the current flowing through the four electrodes is proportional to the distance from the fingers to the four,the controller accurately calculates the ratio of the four currents,draw the location of the touch point.
features1	The infrared touch screen has a groove, fear of strong light,the machine is thicker and heavier,but the price is cheap		Capacitance screen integrated machine more beautiful, slim,it‘s pure plane surface, easy to achieve waterproof function. At the same time, the reaction rate is more sensitive
features2	cheap，applicable large size，explosion proof performance is good， any object can touch， totally enclosed maintenance free，adapt to the harsh environment		High sensitivity，No need to be corrected，Not affected by light
features3	Poor stability，need adjust, may be affected by light		High cost，Need to use finger touch（Or special pen）。The main disadvantage of capacitive screens is the drift.：When ambient temperature、humidity changes，environmental electric field changes，will cause the drift of the capacitive screen, resulting in inaccurate.
features4	Infrared screen can not be done and the shell in the same plane，to a certain extent, increase the thickness，Do not really light, thin		Can direct and seamless fit frame，to a certain extent, to reduce the thickness of the product，Products can be truly beautiful, integral molding
features5	Can not be in the same plane with the housing, there is always a concave and convex surface, waterproof performance is not good		In the same plane with the shell, real waterproof, product care is very convenient, easy to clean
features6	Infrared screen will have action as long as the thing to hinder the infrared ，prone to false action		the advantage of a capacitive screen is that it does not touch any of the items that cannot be electrically conductive.，When not in use, it is not easy to appear the phenomenon of false operation of the contact of the goods,the resolution of capacitive screen is higher, so the product‘s precision is much higher
features7	6points is enough for commercial use		10points is better for play games		Capacitive screen can be used to do with the operating system to do real multi points touch as 10 points touch
features8	At this stage capacitance screen around can be made of black and white, can do logo according to customer demand for personalized directly on top of the capacitive screen, infrared can not do so, just can print logo on outer case of the machine.
