Industriel skærm
Multiteknologivirksomheden 3M afslørede for nylig sin nye 65" Metal Mesh PCAP-berøringsskærm på DIGITAL SIGNAGE EXPO (DSE 2016) i Las Vegas. Ifølge producenten vil skærmene være tilgængelige i størrelserne 32 - 65".
Det særlige ved den teknologi, der præsenteres af 3M, er gennembruddet af de…
Touch Screen
I de senere år har multi-touch teknologi formået at revolutionere HMI-industrien med smartphones, tablets og lignende og inspirere det bredere samfund.
Hvilken berøringsskærm til multitouch?
Multitouch betyder i sig selv, at to eller flere berøringspunkter kan udløse berøringer på et panel på samme…

Impactinator® glas
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.

Glas er et uorganisk, ikke-metallisk materiale, der ikke har en krystallinsk struktur. Sådanne materialer kaldes amorfe og er praktisk talt faste væsker, der afkøles så hurtigt, at krystaller ikke kan dannes.
Typiske glas spænder fra sodakalksilikatglas til glasflasker til kvartsglas med ekstremt…

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 (…

Som en grov retningslinje kan du beregne $ 6400 engangsomkostninger. Derudover er der et køb af ca. 50 stykker af dine individuelle berøringsskærme.
Disse værdier kan ændres, hvis der er valgt særlige kundespecifikke indstillinger, f.eks.:
Optiske antireflekterende belægninger
