Capacitive touch screen UVLED light curing
CLASS: LG UVLED      DATE:2016-3-24    SOURCE:www.longstartech.com.cn

Mobile phone touch screen from the beginning of the resistive touch screen to the current capacitive screen, it has been difficult to find the use of resistance screen from the market, the phone. Due to various advantages of capacitive screen, slowly replacing the resistance screen market. And the development of capacitive screen can not be separated from the use of uvled.

The touch screen is a transparent metal conductive material on the surface of the glass. When the finger touches the metal layer, the capacitance of the contact is changed, so that the frequency of the oscillator connected with the change of the frequency of the measurement can be determined by measuring the touch position to obtain information. In the touch screen and the electric field due to the human body, the fingers and the conductor layer between will form a coupling capacitor, a four electrode current will flow to the contact, and current strength and finger to electrode distance proportional to, in the touch screen controller will calculate the current ratio and strength and accurately calculate the touch point position. Of the double glass touch screen can not only protect the conductor and the sensor, more effectively prevent the external environmental factors impact on the touch screen, even if the screen is stained with dirt, dust or grease, touch screen is still able to accurately calculate the touch location. A mobile phone touch screen is 4 inches, is also quite large, if the traditional curing, low efficiency, energy consumption is large and not environmentally friendly, so it is the use of UVLED light curing machine.

Is mainly UVLED light curing characteristics of environmental protection and fast, it is using UV light curing UV coating equipment, such as UV paint, UV ink, UV, UV coating of photosensitizer and has chemical reaction, instant drying and curing. The overall performance of the cured coatings is an important component of the chemical and physical properties of the coating, and the chemical properties are directly affected by the apparent mass. Can high purity irradiation, heat effects of UV radiation and depth, a high energy and high purity of UV, using the new high energy UV LED, fast curing UV glue, can also greatly improve production efficiency, reduce the cost of equipment materials and does not contain mercury, also won't produce ozone. UVLED light curing machine is generally put light cured coatings on a conveyor belt before, conveyor belt area, ultraviolet irradiation, ultraviolet irradiation, paint, ink, adhesives and other liquid coating of workpiece absorption of UV energy, chain reaction, curing.

The advantages of the UVLED light curing machine for curing the capacitor screen have the advantages of UVLED curing speed and good effect. Easy to operate, the selected components are standardized, operation and maintenance is simple, the use of low cost. The installation is convenient, can be installed on the assembly line, and greatly improves the production efficiency, the existing equipment can pass the 200mm wide conveyor belt. Long service life, UVLED curing machine service life of up to 10000 hours or more. The UV photosensitive reaction of paint, ink, glue produce rapid hardening effect, with no pollution, power saving, fast drying, solvent resistance, wear resistance, low temperature and other characteristics.

Now more and more devices are using touch screen technology, even laptop computers are beginning to appear with touch screen function products. And all of the high-end electronic products are used for the use of capacitive touch screen. And the various advantages of UVLED light curing technology make the capacitive touch screen has been developed rapidly.
