Disadvantages of capacitive touch screen monitors

The advantages of a capacitive touch screen monitor over a glass one are numerous. As the technology is based on capacitance, they are highly sensitive, thereby providing the greatest accuracy. The screens also offer a higher resolution and better display, which is essential for a better user experience. Capacitive touch screens are often the best choice for monitors in certain industries, such as gaming.

Capacitive touch devices can be fully sealed to prevent dust and condensation from entering the display. In contrast, a resistive touchscreen will stop working as soon as it is damaged. The capacitive touch device’s constant monitoring of the electro-static field induced by a human fingertip means it is highly durable and can function even with scratches. This feature also makes it possible to clean a capacitive display easily. Capacitive touch devices are also popular in high-traffic areas.

Principles of operation

The principle of operation of a capacitive touch screen monitor is similar to that of a conventional LCD display. Essentially, the screen is a charging and discharging capacitor circuit, and the object being touched causes a change in the capacitance of the device. This change is recorded by the control electronics, which determines the point of contact. Read on to learn more about this innovative touch screen monitor.

The touch force pressed onto the screen causes a change in the capacitance value of the top layer. This change in resistance changes the response of the entire system. The controller uses the change in resistance to calculate the location of the touch point. It can achieve 99% accuracy and response times of three milliseconds. The microcontroller is connected to the processor in the screen and detects the change.

Materials used

A capacitive touch screen monitor consists of an insulating material and a transparent conductor, most often glass or indium tin oxide. When the human finger touches the capacitive touch screen display, a distortion occurs in an electrostatic field. This electric distortion is measured as a change in capacitance, and this information is used by the control system to determine the position of the finger on the screen.

A resistive touch screen monitor is cheaper to manufacture than a capacitive touchscreen, but requires more frequent charging and recharging. These monitors use a simple principle to measure touch input. The screen is made up of two thin layers separated by a thin gap. The top layer is made of a flexible film based material, while the bottom layer is usually glass or PET film. The layers are lined with a conducting material and are designed so that when the finger touches the screen, it draws a tiny electrical charge. The electrodes are then able to detect the touch commands and identify where the finger is located.


The cost of a capacitive touch screen monitor will vary depending on its specifications and functionality. Some models come with a metal base while others are wall-mounted. A panel monitor costs less than a wall-mounted touchscreen because its metal frame is easy to clean and withstands rough handling. However, a wall-mounted model may require an additional power supply. Regardless of the manufacturer, the price of a capacitive touch screen monitor will be higher than its desktop counterpart.

The cost of a capacitive touch screen monitor varies widely depending on features and mounting location. Some models do not require batteries while others do. When making your decision, make sure to research the different options available before buying a model. Know what the battery type is and how long they last before they require a replacement. The battery life of a capacitive touch screen monitor should last at least five years.
