Overview

YCL Touch Capacitive Touch screen is a high-end multi-point infrared touch screen technology with perfect combination of tradition and innovation. Our touch screen has the features of fast reaction speed, strong anti-environment light ability, good stability and easy integration; With the function of plug and play and without driver, any non-transparent object can change the infrared light and realize the touch operation which is convenient for people to operate and use the digital life and brings the greatest convenience and interactivity to life.

Capacitive or Resisitive Screens?

What is Resistive Touch?

Resistive touchscreens use pressure as input. Made up of several layers of flexible plastic and glass, the front layer is scratch resistant plastic and the second layer is (usually) glass. These are both coated with conductive material. When someone applies pressure to the panel, the resistance is measured between the two layers highlighting where the point of contact is on the screen.

Why Resistive Touch screen?

Some of the benefits of resistive touch panels include the minimal production cost, flexibility when it comes to touch (gloves and styluses can be used) and its durability – strong resistance to water and dust.

Why Capacitive Touchscreens?

What is Capacitive Touch?

In contrast to resistive touchscreens, capacitive touchscreens use the electrical properties of the human body as input. When touched with a finger, a small electrical charge is drawn to the point of contact, which allows the display to detect where it has received an input. The result is a display that can detect lighter touches and with greater accuracy than with a resistive touchscren.

Why Capacitive Touch Screens?

If you want increased screen contrast and clarity, capacitive touch screens are the preferred option over resistive screens, which have more reflections due to their number of layers. Capacitive screens are also far more sensitive and can work with multi-point inputs, known as ‘multi-touch’. However, because of these advantages, they are sometimes less cost-effective than resistive touch panels.

So, which is better?

Although capacitive touchscreen technology was invented long before resistive touchscreens, capacitive technology has seen more rapid evolution in recent years. Thanks to consumer electronics, particularly mobile technology, capacitive touchscreens are swiftly improving in both performance and cost.

we find ourselves recommending capacitive touchscreens more regularly than resitive ones. Our customers almost always find capacitive touchscreens more pleasant to work with and appreciate the vibrancy of image that cap touch TFTs can produce. With constant advancements in capacitive sensors, including new fine tuned sensors that work with heavy duty gloves, if we had to pick just one, it would be the capacitive touchscreen.

Capacitive Touch Screen

What Does Capacitive Touch Screen Mean?

A capacitive touch screen is a device display screen that relies on finger pressure for interaction. Capacitive touch screen devices are typically handheld, and connect to networks or computers via an architecture that supports various components, including satellite navigation devices, personal digital assistants and mobile phones.

A capacitive touch screen is activated by human touch, which serves as an electrical conductor used to stimulate the electrostatic field of the touch screen. However, special gloves that produce static electricity or specialized stylus pens may be used.

Capacitive touch screens are built into input devices, including all-in-one computers, smartphones and tablet PCs.

How does a Capacitive Touchscreen Work?

Capacitive touch screens are built with a thin layer of conductive material, such as copper or Indium Tin Oxide (ITO), printed onto the underside of the display's insulating outer layer. When a finger touches the screen, a small electrical charge is drawn to the point of contact, which effectively becomes a functioning capacitor. The resulting change in the electrostatic field is then measured to pinpoint where the contact took place.

Benefits of Capacitive Touch screen Technology

At present, capacitive touch screen technology offers a number of key benefits:

• High touch sensitivity and accuracy
• Support for multi-touch
• Sharp and vibrant images
• Can be used without a stylus
• Reliability - even cracked or pierced, capacitive touchscreens usually continue to function
• Popularity of the technology grants a level of future-proofing

Capacitance Touchscreen Construction

Several techniques are available to construct a capacitance touchscreen. These include conductive wire construction or the application of transparent conductive materials, such as Indium Tin Oxide (ITO), to a polyester (PET) film layer "sandwich" or to a glass substrate.
