What are the popular sizes for surface capacitive screen?

We all know that surface capacitive screen is a touch screen technology. Structurally, it mainly consists of a transparent conductive layer (usually indium tin oxide ITO) and a glass cover. The ITO layer is evenly distributed on the surface of the screen and is used to detect the capacitance change caused by touch.

Its working principle is based on the conductivity of the human body. When a finger touches the screen, the finger, as a conductor, forms a capacitor with the conductive layer on the surface of the screen. The change in this capacitance is sensed by the electrodes around the screen, and the electrodes transmit the signal to the controller. After calculation, the controller determines the exact location of the touch point based on the location and degree of capacitance change.

It is used in the fields of consumer electronics, industrial control, and commercial display. Here are the popular sizes we have sorted out:

• 3.5 inches-6.5 inches: more common in smartphones, this size is easy to operate with one hand, easy to carry, and can meet basic display and touch interaction needs.

• 7 inches to 12.9 inches: Tablets mostly use surface capacitive screens in this size range, which can provide a better visual experience and are suitable for reading, watching movies, games, etc.

• 4.3-inch to 10.1-inch: widely used in industrial control panels, which can display necessary information and facilitate operators to operate in a relatively compact space.

• 15-inch to 21.5-inch: the operation interface of some large industrial equipment will use this type of larger surface capacitive screen, which can display complex process flows and large amounts of data, and is convenient for multiple people to view and operate at the same time.

• 10.1-inch to 21.5-inch: widely used in self-service terminal equipment, such as self-service ordering machines, self-service ticket machines, etc., which is convenient for users to operate and view information.

• 32-inch to 86-inch: mainly used for advertising machines, conference tablets, etc., the larger size can attract more attention, display more content, and meet the needs of multi-person interaction.
