Master Touch 27 Inch ITO Film Sensor Touch Panel with Crashproof Cover Glass

1. Product Description

Master Touch 27 inch GFF projected capacitive touch screen panel, via a process of sputtering an ITO pattern on a film substrate to make a film-sensor, perceive touch accurately through capacitance coupling.

Capacitive touch panel works through body's current induction.When finger is on or close to touch panel surface,due to body electric field, the user and touch panel surface forms one coupling capacitance. For high frequency current, capacitance is direct conductor, then fingers suck a small current from the contact point, through amplifying and accurately calculating this current signal, the controller works out the touch point position.

The advantages of 27 inch GFF are low capital cost, suitable for small quantity batch production, and light structure.

8. Use Cautions

8.1 Storage Cautions

Storage products must according to the temperature and humidity of product specification and do not accept direct sunlight or heavy weight.

8.2 Move Cautions

Must maintain clear clarity of sample, so please wear fingerstalls or gloves before you contact product. Gloves and mask will have stains and hold product around please when you hold the product. Avoid causing the lead loosing, please don't take the lead when you take out the product.

8.3 Combination Install Cautions

1. Don't put the extra tension to the product. Because the down-lead connection uses the hot pressing combination, do not use extra tension.
2. Installation combined, please don't pull FPC heavily, because pull heavily will make the FPC separated from product.
3. Please don't paste or install other items on the FPC. Such as: pasting a layer FILM or metal plate on the FPC, Because these add-ons will impose an extra pressure on the top of FPC, thus leading to the inner side of FPC become flexible.
4. If there is an aeration slot, when you design the product structure you need notice accessories of a product, they can’t have any liquid and powder.
5. In order not to make the T/P surface pressure, so the distance between the cabinet and our company’s T/P combination clearance shall be maintained 0.2mm-0.5mm.
6. As it will make serious damage on the transparent electrodes to operate in the area of the other than the drive area, we suggest that the design cabinet shall cover the edge of thedrive area for avoiding operating outside the area which would reduce machine life.

8.4 Operation Cautions

1. Do not use sharp objects touch. Please with finger or conductive pen touch
2. After long-term use, please use alcohol to remove product surface uncleanness.
