GG DITO Front Capacitance Touch Screen

What is G+G Projected Capacitive Touch Screen?

Capacitive touch screens are ubiquitous in modern technology, enabling users to interact with devices effortlessly. The G+G structure, consisting of cover glass and glass sensor, plays a crucial role in the performance of these touch screens. Now, we will dive deeper into the world of G+G structures.

Dr Pan: Welcome to DISPLAY Museum. I am Dr Pan, the curator of Museum.

Greg: Hello, Dr Pan. I am Greg. There are so many structures for projected capacitive touch screen. May I ask what G+G structure is?

Dr Pan: Hello, Greg. G+G means cover glass + glass sensor. It is going to need one glass sensor to achieve the touch function. There are two types of G+G structures:SITO and DITO.

Let us look at the structure SITO “One-sheet two-ITO laminated structure”, from top to bottom, Cover glass, OCA, ITO1 and ITO2, and sensor glass.
Another structure DITO “Two-sheet two-ITO laminated structure” , from top to bottom, Cover glass, OCA, ITO1, sensor glass and ITO2.

Advantage: highly accurate, high transmission, multi-touch, good at hand writing, high strength, high reliability, long serving time, suitable for all sizes.

Disadvantage: thicker, sensor glass is easy to be broken when it is hit, long and expensive R&D, cover glass is difficult to be replaced.

Notice: SITO is more reliable than DITO in a harsh environment, but more expensive.

Greg: Dr Pan, is it the most common used since I can see it all the time? And why?

Dr Pan: Yes, it is. What are the most important features for people nowadays? Multi-touch, high-transmission, high reliability. So G+G structure is the winner.

Greg: Thank you, Dr Pan. Now I got it.

Dr Pan: Welcome to contact us if you have any question.

Understanding SITO

SITO is a one-sheet, two-ITO laminated structure that is widely used in capacitive touch screens. It offers many benefits, such as high accuracy, high transmission, and multi-touch capability. Moreover, it is particularly good for handwriting. However, SITO is thicker and more expensive to develop than other G+G structures, and its sensor glass is susceptible to breakage when hit.

The Power of DITO

DITO is a two-sheet, two-ITO laminated structure that is also used in capacitive touch screens. It offers many of the same benefits as SITO, such as high accuracy, high transmission, and multi-touch capability, but with a thinner design. However, DITO is more challenging to produce but less expensive to develop than SITO.

Choosing the Best G+G Structure

When deciding which G+G structure to use, several factors must be considered. These include the desired accuracy, multi-touch capability, and reliability of the touch screen, as well as the specific application’s size and thickness requirements. Ultimately, the choice between SITO and DITO will depend on the particular needs of the user.

Why Choose Capacitive Touch Screens?

And let me tell you, our capacitive touch screen is not only tough, but it’s also incredibly accurate – we’re talking precision rates of over 99%! Unlike those clunky resistive touch screens of the past, our capacitive touch screen only needs to be calibrated once for a lifetime of top-notch service. And the cherry on top? Our touch screen supports multi-touch technology, so you can control your device with intuitive, effortless gestures.

So what are you waiting for? Treat yourself to the ultimate touch experience with our amazing capacitive touch screen today!

Limitations of Capacitive Touch Screens

Isn’t it amazing how well the capacitive touch screen performs? But let’s be real, it’s not perfect – it’s got a lot of downsides. Unlike the resistive touch screen, it’s not as stable and can be easily affected by the environment – things like temperature, humidity, electromagnetism, and strong light can all throw it off. And let’s not forget that it’s super sensitive to changes in electricity. Plus, you’ve got to keep it squeaky clean all the time – any dirt or grime on the surface can mess up the accuracy of your touch.

And here’s the kicker – you can only use it with your fingers! That’s right, pencils, plastic, metal – forget about it. They won’t work. And making a big-sized one? That’s a whole other technical challenge. We usually have to use infrared technology to make touch screens that are larger than your average Joe.

So, while the capacitive touch screen is pretty darn impressive, it’s got its fair share of quirks and limitations.
