The principle of touch display is actually very simple. Simply put, a touch screen is installed on the display to become a display with touch function. The most popular option in the market is LCD touch displays (CRT has gradually withdrawn from the market). According to the different installation of touch screens, they are generally divided into four types: resistive, capacitive, acoustic, and infrared; The touch displays on the market mainly use resistive touch screens because their installation is relatively simple. There are professional companies in China that specialize in self-designed integrated touch displays. Unlike those in the market that are modified from other displays, modified touch displays are prone to quality issues, while integrated development and design touch displays are less prone to damage.
When viewed from the front, the touch monitor is not significantly different from a regular monitor, but when viewed from the back, it has an additional signal line that connects to the touch screen. Ordinary displays generally do not require specialized drivers when in use, while touch displays must have dedicated touch screen drivers when in use, otherwise touch operations cannot be performed.
