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.

5. Function Test
5.1 Inspection methods and conditions
Connect jigs (Supplier provide test jigs and test software) to a
computer; test touch function of products in normal electrical
characteristics.
5.2 Inspection standards
Don't allow any function abnormalities.
6. Drawing
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.
