The document discusses various types of display modules used in interactive retail displays, including capacitive touch screens, resistive touch screens, and touch panel LCD displays. It outlines the functionality of each type, noting that capacitive and resistive technologies are common in touchscreen LCDs. Additionally, it touches on thin film transistor (TFT) technology used in monitors, highlighting its complexity.

1. Display modules
used in interactive
displays in retail
establishments

2. Capacitive Touch Screens:
A capacitive touch screen display is a digital interface
that may be used to input data using the fingers or
other types of specialized touch input devices
(Stylus).

3. Resistive Touch
Modules:
Another sort of digital
interface is a resistive touch
screen display. However, it
functions based on the
screen's mechanical pressure.

4. Touch Panel LCD
Display Modules:
To support touch functionality,
the main LCD screen of the touch
screen LCD comprises additional
layers. Capacitive or resistive
touchscreen technology is
typically used in touchscreen
LCD displays.

5. Thin Film
Transistor touch
screen monitors:
TFT stands for this term. The display
technology used here is a bit
complicated. Each pixel of the TFT
module's display is a unit matrix
generated with a transistor and also
has a capacitor.
