Different Types of LCD Monitors

11.06.2023

– Twisted Nematic Display: The new TN (Twisted Nematic) LCD production can be carried out most frequently and use different types of displays in various industries. These monitors are most often used by gamers because they are inexpensive and have fast response times compared to other monitors. The main disadvantage of these monitors is their low quality and partial contrast, viewing angles and color reproduction. However, these devices are sufficient for daily operations.

– In-Plane Switching Display: IPS monitors are considered the best LCD because they offer good image quality, higher viewing angles, vivid color accuracy and difference. These displays are primarily used by graphic designers, and in some other applications, LCD require the maximum potential standard to reproduce images and colors.

– Vertically Aligned Panels: Vertically Aligned (VA) panels between Twisted Nematic and In-Plane Switching Panel Technology are positioned anywhere in the center. These panels feature the best viewing angles and color reproduction and higher quality than TN-type displays. These panels have very short response times. However, these are more reasonable and more suitable for everyday use.

- The panel's structure produces deeper blacks and better colors than twisted nematic displays. Several crystal arrangements allow for better viewing angles compared to TN-type displays. There's a trade-off with these monitors, as they're expensive compared to other monitors. And they have slow response times and low refresh rates.

– Advanced Fringing Field Switching (AFFS): Compared to IPS displays, AFFS LCD offer the best performance and broad color reproduction. The application of AFFS is very advanced because they reduce color distortion without compromising wide viewing angles. Typically, such displays are used in highly advanced and professional environments such as viable aircraft cockpits.

– Passive and Active Matrix Displays: Passive matrix LCD work with a simple grid, so specific pixels on the LCD can be supplied with electrical charge. One layer of glass forms the columns, while the other layer forms the rows, which are designed by using a transparent conductive material such as indium tin oxide. Passive matrix systems have major disadvantages, especially slow response times and inaccurate voltage control. The response time of the display mainly refers to the ability of the display to refresh the displayed image.

– Active matrix LCD mainly rely on TFT (Thin Film Transistors). These transistors are small switching transistors and capacitors placed in a matrix on a glass substrate. When the correct row is activated, the charge can be transferred down to the exact column so that a specific pixel can be addressed, and since all additional rows intersected by that column are turned off, the charge can be obtained by simply specifying the capacitor next to the pixel.
