An indispensable tester to the character writing durability test for the analog resistive touchpanel

The tester consists of a X-Y blotter, a control computer and program software for the character writing test.

The writing test is made by writing 3 kinds of characters (50 katakana letters,alphabet capital and small letters), straight lines and lattices.
The position coordinates as well as the size of letters, straight line and lattice for writing can be changed freely. Also the load of the pen and its writing speed can be changed freely.
A standard test goes with an automatic writing of the 50 katakana characters in a 20mm square for 100,000 times with a plastic pen of tip 0.8R and confirms whether any abnormalities have occurred on the writing surface or the function (linearithy, etc.) (The linearity is measured with another tester.)
