Touch Screen Controllers

What are Touch Screen Controllers?

Touch screen sensor integrated circuits, also referred to as touch screen controllers, are types of semiconductor equipment that are used to transform user behaviors made available on the screen that is processed by a device. They are manufactured to detect the input built into the LCDs of touch screens. Touchable screen controllers are primarily used in the manufacturing and engineering industries, whereby LCDs work as control panels for automation or control systems like machinery and specialized equipment. 

How does a Touch Screen Sensor IC work?

Touch Screen Sensor integrated circuits embedded in the sensors convey touchable actions electronically, making sure the utilization of a touch screen device as an input technique instead of a keypad and mouse. A pen stylus interrupts input and is also made available in the most used integrated circuit types. The low power mode has benefited from the addition of an integrated circuit; this is enabled with the help of a touch screen since stylus pen utilization has improved over here. 

What are the most used types of Touch Screen Sensor ICs?

Touch screen sensor integrated circuits are found in the industry in many distinct types, including:

• Capacitive Touchable Screen Controllers - The Integrated Circuits are manufactured to be compatible with emerging technologies’ screen panels that are covered by indium tin dioxide. This device conducts a continuous electrical current throughout the sensors to observe any changes that happen in the electrical charge by the time the screen gets touched.
• Resistive Touchable Screen Controllers - These types of integrated circuits generate a sensitive electrical layer. The variation in resistance on this layer is recognized, such as touch events, which are chosen by the controller for the data processing mechanism.
• Since these capacitive and touch screen devices are digitized at the same time, the touch screen digitizer is an integrated circuit that is specifically designed to transform analog touch comments into digital formats. These ICs are also available with a variety of interface types, including serial, SPI (Serial Peripheral Interface), UART (Universal Asynchronous Receiver-Transmitter), and Serial SPI. Additionally, a variety of pin configurations built into the IC itself are available.

Applications of Touch Screen Sensor ICS

Touchscreen Sensor integrated circuits are commonly used in a wide variety of applications, such as:

• Point-of-sale terminals
• Mobile phones
• Tablet devices
• ATM machines
• Touch screen monitors
