LCD Module Car Touch Panel Resistive 4 Wire For Vehicle GPS
Navigation
In-vehicle GPS Navigation:
More and more in-vehicle devices are with touch funciton, such as
built-in GPS navigation together with DVD player and radio,
muilt-rearview mirror camera etc. And the performance is better and
better with the devopment of touch technology. Still, a lot of such
device takes the analog resistive techonolgy. The sizes are usually
from 6 inches to 10.1 inches.
4 wire resistive touch is typically glass bottom and film top, but
they can be film + Film. It consists of a conductive bottom layer
of either glass or film and a conductive top film layer, separated
by extremely small, transparent spacer dots. A voltage is applied
across the conductive surface. When pressure from a touch is
applied to the top layer, it is compressed and makes contact with
the bottom layer resulting in a voltage drop. This change is
detected by the controller. By alternating the voltage signal
between the top layer and the bottom layer, the X and Y coordinates
of the user’s touch are computed. Each layer serves as one of the
axes.

Description:
1. Providing Touch Panels Since 2009
As a manufacturer, we provide customized touch panels, including
4-wire resistive touch panel, 5-wire resistive touch panel,
capacitive touch panel, digital touch panel etc. Mostly, we are
able to offer touch panel solutions in a short time.
Currently, we have been supplying touch panels to clients domestic
and abroad. Samsung and Nintendo are two well-known companies of
them.
2. PRC National Standard High Quality Manufacturer
Audited by TUV, our factory complies with the national standard of
high quality manufacturer through the following aspects: genuine
manufacturer, dedicated export team, research and development
capability, trustworthiness and reputation, high quality products,
considerable company size, social and environmental responsibility,
customer service capability.
In 2010, we passed ISO 9001:2008 International Management System
and ISO 14001:2004 + Cor 1:2009 Environmental Management System.
3. High Stability of Staff Makes High Stability of Quality
Over 60% workshop workers have been working in our company since 3
years ago and it is more than 80% of the management. The philosophy
of people-oriented management makes all staff like one.
Additionally, our sales team are able to offer 4 languages service,
including Japanese, Korean, English and Chinese. And we are always
trying our best to support our clients.
4. Dust-free Workshops and Specialized Equipment
In the line of manufacturing touch panels, dust-free workshops and
specialized equipment can basically guarantee the quality,
especially the cleanliness of both resistive touch panels and
capacitive touch panels.
10000-class dust-free workshops cover an area of over 2000 square
meters, in which more than 200 square meters is equipped
with100-class dust-free workshops. Moreover, some key equipment is
introduced from Taiwan, such as IR ovens, Laser machines, etc.
5. Brand Raw Materials Only
In order to produce satisfactory touch panels, we only use brand
materials. In this case, our production has high efficiency.
| Raw Material | Supplier |
| ITO Film | CSG HOLDING |
ITO Glass | CSG HOLDING or TOKEN |
| Cover Lens / Glass | AGC GROUP |
| Conductive Silver Paste | ASAHI or INKTECH |
| Printing Ink | SEIKO |
| OCA | 3M or LG |
6. Detail Makes Difference
Perfect details make our products perfect. Silkscreen of our
analogue resistive touch panels and projected capacitive touch
panels has smooth surface, smooth line, uniform thickness and the
linearity is below 1.5%; the edge is smooth with tolerance below
0.1mm; minimum width of silver line and distance between lines is
0.15mm.
Silk-printing, laminating, cutting, FPC bonding etc. are all
operated by automatic machines and skill-experienced workers.
Almost everything is under our control.
7. 100% Inspection
Every stage of production process is focused on a lot to avoid
mistakes and regarding the cleanliness of appearance and function,
we carry out 100% inspection. What we care most is that each piece
touch panel delivered from our warehouse has to meet our clients’
requirements.
8. Safe Packaging and Delivery
Up till now, every order of our touch panels has reached our
clients abroad successfully without any damage. We pack touch
panels with blister tray or foam box as requested first, certainly,
there is a piece of protective film on it; and second, put into a
bag and make it vacuum; lastly, put into a carton box.
