DIFFERENT TYPES OF TOUCHSCREEN

DIFFERENT TYPES OF TOUCHSCREEN

Touch screens were introduced in mobile phones in the year 2000 for the first time and have become an integral part of almost every smartphone today. There are several types of touch screens used in monitor and mobiles. Some of the most popular are discussed below:


TFT LCD

TFT (Thin Film Transistor) LCD display is used for better image quality and high resolution. Since they are cheap to manufacture, they are found in budget phones usually.


IPS-LCD

IPS (In-Place Switching) LCDs are somewhat the advanced version of TFT LCDs in a way that they offer improved displays and are more battery friendly. Hence, they are found in high end phones.


RESISTIVE AND CAPACITIVE

There are generally two types of touchscreen LCD displays; Resistive and Capacitive. Resistive touchscreen has two layers of conductive material with a small gap between them while capacitive touchscreen consists of a layer of glass coated with transparent conductor. Capacitive screens tend to be more responsive than resistive screens and are therefore found in high end phones mostly.


OLED

OLED (Organic Light Emitting Diode) is a newer technology used in mobiles and monitors for display. They are better than LCDs because they offer fast response times, wider viewing angles and higher brightness. AMOLED (Active-Matrix Organic Light-Emitting Diode) and SUPER AMOLED displays are types of OLED display.
