VGA LCD monitors and ordinary LCD monitors should be the difference between touch LCD monitors and non-touch LCD monitors. VGA should refer to the resolution of the LCD monitor, not the type of monitor.

First of all, the touch LCD has a touch screen function, which can realize the touch operation of the finger, and then transmit the information of the touch point to the computer, and respond to different operations and instructions through the processing of the computer. However, ordinary liquid crystal displays cannot be touch-operated, and computer operations can only be completed through external devices such as a mouse and a keyboard.

Secondly, there is a transparent conductive film between the display panel and the touch screen layer of the touch liquid crystal display. This conductive film can sense the touch operation and convert the signal of the touch screen into a digital signal that can be recognized by the computer, thereby realizing touch.

Furthermore, the structure of a touch LCD display is different from that of an ordinary LCD display. Touch LCDs are usually thicker and in most cases have two glass screens, a display and a touchscreen. However, ordinary liquid crystal displays only have a single screen structure.

Generally speaking, touch LCD is suitable for occasions that require human-computer interaction, and has a wide range of applications in information query, navigation systems, game interaction, vending machines and other fields. Ordinary LCD monitors are suitable for general computer office, audio-visual entertainment and other daily use occasions.

In addition, the concept of VGA should refer to the resolution of the liquid crystal display, that is, the number of arrangement of pixels displayed on the screen. A VGA (Video Graphics Array) monitor refers to a display with a resolution of 640x480 pixels. With the development of the times and technology, the resolution of the current liquid crystal display has been generally improved, and it has become a high-definition liquid crystal display, 2K liquid crystal display, 4K liquid crystal display, etc.
