Projected capacitive
Projected capacitive glass touch screen is a type of touchscreen that uses a matrix of electrodes under a transparent layer of glass. These touch screens are used on the majority of tablet computers and smartphones. They are highly sensitive and provide a multi-touch experience. This technology is perfect for both indoor and outdoor applications.
There are two main types of projected capacitive touch screen sensors. The first type is surface capacitive. In this case, the touch point is detected using a transparent conductive film. Most of these are ITO.
Another type is mutual capacitive. This technology detects the touch point by measuring the change in the electrostatic field. Mutual capacitive is more sensitive to touch commands, allowing for a more accurate detection.
Surface capacitive touchscreens are also made of a transparent conductive film. They offer high sensitivity and can be operated using gloved hands.
Projected capacitive glass touch screens are also Custom Glass Touch Screen available in a flush mount design. For this design, the front layer of the glass is laminated. Each of the four corners of the glass sublayer has electrodes. A protective layer is also added to protect the electrodes.
Projected capacitive glass is ideal for use outdoors. It’s strong and withstands impacts. Since it’s a solid-state technology, it offers longer life and increased reliability.
These touchscreens are designed to last a lifetime. You can also buy custom-made PCT touch-screens, which are ideal for custom solutions.
These devices can also be customized with your company logo. Depending on your needs, you can purchase a projective capacitive touchscreen kit that includes a discrete controller board. With this device, you can accelerate time to market, as well as offer a USB-HID-compliant solution to your customers.
If you are looking for a touch screen solution that can handle a large amount of usage, consider a projected capacitive touch screen. Its thin profile makes it a perfect choice for both indoor and outdoor applications.
Unlike resistive touch screens, projected capacitive touchscreens don’t have moving parts. These make it possible for more delicate designs. Whether you’re designing a POS machine or a mobile phone, a projected capacitive touch screen is a good option.
Glass-Film-Glass (GFG)
Custom Glass-Film-Glass (GFG) touch screens offer a responsive touch screen experience. They combine the feel of a capacitive touchscreen with the input functionality of a resistive touchscreen. The result is a touch screen that is ideal for use in harsh environments.
There are many different custom glass touch screens available to choose from. To make a smart choice, it’s important to know the technical specifications of each option. Some of the factors to consider include the type of sensor, the mechanicals, and the digital signals.
If you want your custom touch screen to be durable, you might consider opting for a laminated glass model. This increases impact resistance by up to five Joules, and is also more resistant to scratches.
You can also add a privacy film to prevent people from viewing confidential information. In addition, a circular polarizer can be installed on the top surface to block light reflections from the interior surfaces. By doing so, system developers can integrate touchscreens into outdoor applications without having to rectify the LCD.
If you’re looking for a durable touch screen for public or industrial use, opt for a GFG resistive touch panel. It uses a thin layer of electrically conductive film on a glass substrate. It’s coated with a low-reflection coating, and is ideal for working in harsh environments.
Glass-Film-Glass (GFG) structured touch panels are highly conductive, and are also resistant to most cleaning agents. Their structure also provides excellent resistance to flying sparks from welding operations.
GFG resistive touch screens are available in 4-, 5-, and 8-wire designs. They can be bonded to a full sheet of polyester, or bonded to a full glass or polycarbonate panel. For added durability, you can incorporate a full ESD shield into the design.
You can also opt for a custom glass touch screen with a Glass Rigid Backer, which adds extra protection. A PC or Glass Rigid Backer improves the contrast and light transmission of your touchscreen.
These types of touch screens are suitable for a wide range of applications. From kiosks and retail storefronts to industrial control computers, a custom glass touch screen can be configured to meet your needs.
Noise shielding
For a custom glass touch screen, noise shielding film is a critical component to prevent malfunction of precision equipment. It can also reduce the intrusion of electromagnetic waves.
Common-mode noise is a type of electrical noise, and is generated when power and ground supplies fluctuate relative to earth ground. Touchscreens can be affected by this kind of noise, but only when a finger touches the screen.
There are two main types of noise: radiated and conducted. Radiated noise is emitted into the air, while conducted noise is transmitted through conductors.
Injecting noise into a touchscreen device can cause large amounts of jitter and corrupt finger tracking. This can Custom Glass Touch Screen cause false touches, as well as locking of the touchscreen.
To combat display noise, high-frequency scanning can be used. This avoids the first few harmonics of LCD noise. High-frequency scanning can also improve display immunity.
EMI (electromagnetic interference) shielding can be used to protect the entire display. An EMI shielding mesh is a lightweight, flexible material that is used to absorb EM waves. The shielding can be made of conductive metal, copper plate, or stainless steel. EMI shielding gaskets must be soft enough to not interfere with the touch function. EMI shielding may also require heat dissipation features.
EMI shielding is a very important feature for many industries. Using EMI shielding film can help reduce the intrusion of electromagnetic waves and eliminate acoustic leakage.
Besides EMI shielding film, there are other options to reduce noise. For instance, a privacy filter can be added between the touch screen and the monitor. Adding a privacy filter decreases the angle of view, making it impossible to see the screen from the side.
Additionally, capacitive touch sensors can be shielded to reduce the amount of electromagnetic interference. In addition, some device manufacturers laminate the sensor directly onto the display. By doing this, there is no need for an external sensor.
Having a high SNR capacitance profile reduces the peak-to-peak amplitude of background noise. With a high SNR capacitance profile, a typical signal-to-noise ratio of over 30 dB can be achieved.
