2. Liquid optically clear adhesive - Wikipedia

   en.wikipedia.org/wiki/Liquid_optically_clear...

   Reflection is caused by an impedance mismatch between air and the glass. The reflection makes the white brighter, but dilutes black and other colors, which decreases contrast. LOCA suppliers aim to match the refractive index of glass and clear plastic PMMA (refractive index approximately 1.5) used in displays to minimize loss. LOCA suppliers ...

3. Screen protector - Wikipedia

   en.wikipedia.org/wiki/Screen_protector

   Plastic screen protectors cost less than glass and are thinner (around 0.1 mm (0.004 in) thick, compared to 0.3 to 0.5 mm (0.012 to 0.020 in) for glass) [2] and more flexible. At the same price, glass will resist scratches better than plastic, and feel more like the device's screen, though higher priced plastic protectors may be better than the ...

4. Samsung Galaxy S22 - Wikipedia

   en.wikipedia.org/wiki/Samsung_Galaxy_S22

   The S22 Ultra retains its predecessor's 108 MP sensor with 12-bit HDR. It also has two 10 MP telephoto sensors with 3x and 10x optical zoom as well as a 12 MP ultrawide sensor. The front-facing camera uses a 10 MP sensor on the S22 and S22+, and a 40 MP sensor on the S22 Ultra. The Galaxy S22 series can record HDR10+ video and support HEIF. [6]

5. Polycarbonate - Wikipedia

   en.wikipedia.org/wiki/Polycarbonate

   The main polycarbonate material is produced by the reaction of bisphenol A (BPA) and phosgene COCl 2. The overall reaction can be written as follows: The first step of the synthesis involves treatment of bisphenol A with sodium hydroxide, which deprotonates the hydroxyl groups of the bisphenol A. [6] (HOC 6 H 4) 2 CMe 2 + 2 NaOH → Na 2 (OC 6 ...

6. Poly(methyl methacrylate) - Wikipedia

   en.wikipedia.org/wiki/Poly(methyl_methacrylate)

   The larger circular clear black area represents the larger outer side of the thick one-piece plastic cone "window". Being transparent and durable, PMMA is a versatile material and has been used in a wide range of fields and applications such as rear-lights and instrument clusters for vehicles, appliances, and lenses for glasses.

7. Aluminium oxynitride - Wikipedia

   en.wikipedia.org/wiki/Aluminium_oxynitride

   Aluminium oxynitride (marketed under the name ALON by Surmet Corporation [3]) is a transparent ceramic composed of aluminium, oxygen and nitrogen.Aluminium oxynitride is optically transparent (≥80% for 2 mm thickness) in the near-ultraviolet, visible, and mid-wave-infrared regions of the electromagnetic spectrum.

8. Liquid-crystal display - Wikipedia

   en.wikipedia.org/wiki/Liquid-crystal_display

   An LCD screen used as a notification panel for travellers. Each pixel of an LCD typically consists of a layer of molecules aligned between two transparent electrodes, often made of indium tin oxide (ITO) and two polarizing filters (parallel and perpendicular polarizers), the axes of transmission of which are (in most of the cases) perpendicular to each other.

9. Matte display - Wikipedia

   en.wikipedia.org/wiki/Matte_display

   Reflection of a fluorescent ceiling light, as seen in a glossy screen (left) and matte screen (right). A matte display is an electronic display with a matte surface. Matte displays feature a light-scattering antireflection layer, which reduces reflectivity at the cost of decreased contrast and color intensity under dimly lit conditions. [1]
