Introduction: the world’s first large-size touch screen performance general-purpose tester
coming onto market.
Large-size touch screen has been widely used due to its continuous R&D, manufacturing technology
breakthrough and efficiency promotion, the fields involve teaching, meeting training, product display,
radio and TV industry, war industry, media industry, financial industry and real estate industry, etc.
Large-size touch screen has owns large market demand owning to its incomparable user
For example: the touch screen promoted by Infocus company supports simultaneous touch of 32
points and Win8 and Android operating system:
And touch screen promoted by SHQRP company supports multi-touch ALO：
There is no test method or machine for large-size touch screen in this industry before, but infinity
machine has successfully developed the world’s first large-size touch screen performance general-
purpose tester through more than half year’s striving to make technological breakthrough, and all this
owns to its 19 years’ focus on R&D of testing industry, manufacturing technology promotion and many
years’ touch screen testing experience. This touch screen tester meets multi-point touch control
performance test for infrared screen (17-120 inch), optics screen, electronic whiteboard and
capacitive screen, and meets single test for finished product and touch screen, thus it is really the
necessary equipment for large-size touch screen manufacturer.
Difficult point 1 of technological breakthrough-structural design:
This equipment has 6-axis (X-Y-Z-R-A-B) driving structure, so there are many difficulties: how to
guarantee synchronicity of Y axes on the right and left? How to guarantee the parallelism, verticality
and coaxiality of each axis? How to guarantee the positioning accuracy and repeated accuracy of
each axis under high-speed operation? How to guarantee high balance and low jitter of the tester
with a large stroke in high-speed operation?
Difficult point 2 of technological breakthrough-machining accuracy:
As it is known to all, when the equipment size is quite large, the mounting mandatory surface of each
axis must be quite precision, otherwise this is no guarantee of parallelism, verticality and coaxiality of
each axis. However, the dimension of RS-5610V tester is amazing: W3660xD2570xH2140mm, thus
the machining accuracy demand of each key component can be imaginable.
Difficult point 3 of technological breakthrough-how to assemble and debug:
As for such a large tester, how to assemble, debug and calibrate? And can the calibration accuracy
reach technical requirements of test (±0.01mm)?
After grinding, the accuracy of the marble platform reaches national 000 grade, lifting on the special
All parts mounting steps accept strict tolerance adjusting, guaranteeing the accuracy.
Difficult point 4 of technological breakthrough-up to 32-point touch:
Most of large-size touch screen adopt HID protocol communication, and most of them support 2-
point, 4-point, 10-point, 16-point, 32-point and even 64-point simultaneous touch, how to deal with
data of dozens of coordinate points? Its logical algorithm is indeed a difficult point that many
enterprises can’t exceed.
Difficult point 5 of technological breakthrough-simultaneously compatible with Win8 and Android
Large-size touch ALO is generally based on Win8, Win10 or Android operation system development,
then it requires our touch screen test system must be compatible with Win8, Win10 or Android
operation system. When doing finished product testing, multi-touch information can be transmitted to
software for analysis and data output through Wifi.
110-inch touch screen clicking lineation tester sent to Wuhan Foxconn:
On October, 2015, leaders of Wuhan Foxconn visited equipment in our factory, and quite interested in
our touch screen clicking and lineation tester, more importantly, it can meet test requirements of their
large screen to be on line. Therefore, the world’s first 110-inch touxh screen clicking and lineation
tester was born in the manufacturing base of infinity machine.
The coming of 110-inch touch screen clicking and lineation tester not only proves the R&D ability of
our company, but also makes our strength recognized by famous enterprises all over the world.
110-inch touch screen clicking and lineation tester: test space is W1450xD2450xH250mm,
supporting 32-point simultaneous touch and high-speed test of 500mm/sec, and it has advantages of
high precision and low noise, and repeating accuracy reaches ±0.01mm.
