Technical terms
What actually means “CTP | RTP”
The CTP (Capacitive Touch Panel) is more expensive compared to an RTP, but has a much longer service life. The structure consists of a two-layer coordinate network. The lower electrode (glass with ITO) is divided into columns and the upper electrode into rows.
Customized Display Elements «Coverlens»
The cover lens - also known as a cover glass or front glass - protects the display from scratches, dirt and UV radiation. The cover lens is bonded to the display. You can adjust many things with a cover lens. Most important are the size and thickness of the glass. But the hardness also plays a role, because no one likes to have scratches on the display.
Customized Display Elements «Backlight»
The light that backlights the display is called backlight. Two points play a central role in ensuring that the lighting is optimal. The first and most important point is brightness. Since around 90 percent of the light is absorbed by LCDs, polarisation foils or other components, sufficiently bright LEDs are needed.
What actually means “Full array Local Dimming”?
Most industrial TFTs today have an edge LED backlight. The backlight illuminates the entire surface of the TFT, so if we reduce the brightness of the backlight, it affects the entire TFT surface at the same time.
What actually means “IPS”?
(In-Plane Switching) IPS technology works in a similar way to TN technology. The difference is that the LC crystals are arranged in parallel and twisted by 90 ° in the [...]
What actually means “VA”?
A VA display (Vertical Aligement) consists of two linear polarizing filters rotated 90° to each other and some other stuff. Between the filters are two transparent electrodes (a pixel electrode and a common counter electrode). These usually consist of a glass plate with an ITO layer (indium tin oxide) applied. On top of this is the orientation layer. The elongated liquid crystals are embedded in between.
What actually means “TN”?
The most common of all LCD technologies is TN (twisted nematic) technology. A TN display consists of several TN cells that function like a kind of water tap in which light flows instead of water.
