LCD screen
A liquid crystal display (LCD) is a Liquid Crystal Display. On a flat screen, it uses a digital display mode. It is an active matrix screen with high-quality images.
LCD should not be confused with TFT (Thin film transistor). The latter represents a variation of the LCD screen. Moreover, LCD-TFT screens are currently the most popular with users.
The two main criteria that differentiate LCD screens from CRT screens are lighting and slab.
Lighting
Thanks to the advanced settings of the lighting mode, it is now possible to access more or less extensive fields. The LCD screen has three main lighting adjustment systems: transflective- transflective.
- Transmitted lighting: The screen works with the traditional backlight system that adjusts brightness, but has a limited lifespan and brightness.
- Reflective lighting: the LCD screen works with the outdoor light reflection system and no longer requires a brightness adjustment. This is a very common feature for watches, whose camera watchthere spy camera watchthere watch camera spy vision nocturnal and the watch spy full hd. However, when the lighting environment is low, this system shows signs of weakness.
- Transflective lighting: it combines the features of the two previous systems.
The slab
This is the essential element for LCD technology. It includes the entire electronic system and liquid crystals. The slab affects the quality of the screens. There are several types, namely:
- The TN slab: fast and economical
- The IPS slab: for a good color rendering
- The VA slab: for a faster access.
