Industriell skjerm
Multiteknologiselskapet 3M avduket nylig sin nye 65" Metal Mesh PCAP berøringsskjerm på DIGITAL SIGNAGE EXPO (DSE 2016) i Las Vegas. Ifølge produsenten vil skjermene være tilgjengelige i størrelsene 32 - 65".
Den spesielle egenskapen til teknologien som presenteres av 3M er gjennombruddet av de…
Touch Screen
De siste årene har multi-touch-teknologi klart å revolusjonere HMI-bransjen med smarttelefoner, nettbrett og lignende og inspirere storsamfunnet.
Hvilken berøringsskjerm for multitouch?
Multitouch i seg selv betyr at to eller flere berøringspunkter kan utløse berøringer på et panel samtidig.

Impactinator®-glass
Heat Treating: Where the annealed glass is subjected to a special heat treatment in which it is heated to about 680°C and afterwards cooled.
Chemical Strengthening: The glass is covered by a chemical solution which produces a higher mechanical resistance. Chemically - strengthened glass has similar…

Drift - a gradual loss of accuracy in the alignment of a touchscreen system. Over time, touches to the screen will gradually drift, or move away, from their proper on-screen targets. If the alignment of a touchscreen becomes poor, the touchscreen will need to be calibrated to restore proper…

Gloss Level - a measure of the amount of non-specularly or diffusely reflected light from a surface. A highly diffuse surface has a low gloss level.

Decibel (dB) - a unit of power loss or attenuation used in EMI/RFI shielding:
1 decibel = 10 log (Power in/Power out).
A 3dB loss is a fifty percent power reduction.

Glass er et uorganisk, ikke-metallisk materiale som ikke har en krystallinsk struktur. Slike materialer kalles amorfe og er praktisk talt faste væsker som avkjøles så raskt at krystaller ikke kan dannes.
Typiske glass spenner fra soda-lime silikat glass for glassflasker til ekstremt høy renhet…

Hydrofluoric acid is a solution of hydrogen fluoride in water. While it is extremely corrosive and dangerous to handle, it is technically a weak acid. Hydrogen fluoride, often in the aqueous form as hydrofluoric acid, is a valued source of fluorine, being the precursor to numerous pharmaceuticals (…
