There are many industries use capacitive touch screens into their device. It is becoming more and more popular in our lives. So how to choose 5”, 7”, 10.1”, 15”,15.6”,17”,18.5”,19”,21.5”27” capacitive touch screen Solutions? Many specifications and functions may affect your choice, such as industrial-grade touch screens, medical touch screens or consumer-grade touch screens. Because they may not know much about capacitive touch screens, many customers will have difficulties with so many choices.
Know which technology and durability are suitable for your product's application, and choose the type and size of capacitive touch screen solutions that suits you. If you need an entry-level small 1.5 inch to 10.1 inch touch screen, or a more robust and feature-rich touch screen solution, Dingtouch can customize and manufacture the correct capacitive touch screen solution for your project, no matter how big or small.
Many of today's consumer, medical equipment, industrial control and other fields still use capacitive touch screens. We all know that there are also some product devices that use resistive screens, infrared touch screens, and acoustic wave touch screens. Each of them has its own unique advantages, but there is definitely no perfect technology in the world that can fit all product applications. However, there many device use the capacitive touch screens widely and it gradually become mainstream technology.
Although capacitive touch screens are very popular, how do we choose the best capacitive touch screen solution? We should choose based on overall cost requirements, product application environment and project annual consumption, instead of blindly pursuing perfection, which requires all the requirements of a touch screen.
Because consumer touch screens are different from medical and industrial touch screens, their user types are different, so they have different quality requirements for touch screens. It should be necessary to choose the functions they need in the specific environment operation.
The touch effect of the touch screen, the time it is in the key operation and the environment in which it is applied are all important factors worth considering. Because the high-quality capacitive touch screen has very good touch performance and can adapt to various harsh environments. The average lifespan of basic high-quality products can be as long as 6 years.
Other factors worth considering are the type of power supply require for operation, operating temperature, storage temperature, shock-proof enhancement technology, waterproof technology, sunlight readable technology, optical bonding, and so on. Dingtouch's capacitive touch screen can work anywhere.
Total cost of ownership (TCO) is a financial estimate designed to help buyers and owners determine the direct and indirect costs of a product or system. It is a management accounting concept that can be used in full-cost accounting and even ecological economics, including social costs. Dingtouch touch screen solutions give you real peace of mind, because their average life span is more than 6 years, and they provide a 12-month reliable warranty. As long as each product has a process of use, every year they will discount. But we are to provide you with the most cost-effective solution and long-life touch screen. In this way, it may end up costing you $0, because it will pay for itself in many years.
If for any reason, any Dingtouch capacitive touch screen has a manufacturing defect. Please contact our colleagues immediately and describe in detail what are the problems with the touch screen. As soon as we receive your feedback, we will submit to our after-sales department immediately, and then we will solve the problem for you as soon as possible.
The working principle of the capacitive touch screen is mainly based on the current induction of the human body. It is a four-layer composite glass screen. The inner surface and the interlayer of the glass screen are each coated with a layer of ITO. The outermost layer is a thin layer of silica glass protective layer. The interlayer ITO coating is used as the working surface. Four corners lead out. Electrode, the inner layer of ITO is a shielding layer to ensure a good working environment. So you only need to touch lightly to achieve touch.
When you look at the capacitive touch screen carefully, it may look like a thin piece of material. But what you actually see are several very thin layers of components. These layers include a combination of cover, OCA, Sensor+FPC, etc. These components are the most common structure of capacitive touch screens.
Cover, many product applications now use glass. But some use PMMA materials, such as those used in games. Therefore, different product applications will choose different cover materials. Generally speaking, we use 6H tempered glass or 7H Gorilla/Corning glass. The cover does not have any touch function, it just plays a role in protecting the Sensor.
OCA is a kind of water glue, which serves to glue the cover plate and Sensor together. We use OCA with a thickness of 0.25mm. If it is a large size, we use SCA bonding, their function is the same, but the types are different.
Sensor is the most important part of the touch screen. Because it controls the touch function, it generally has ITO glass+FPC+chip+components. The chips we recommend for different product applications are also different. Because some product applications need to support wearing gloves and touch with water, this requires higher-quality chips.
The choice of capacitive touch screen solution will affect many aspects of its performance. In particular, it will directly affect these aspects:
Response time and input lag
So choosing a high-quality capacitive touch screen is very important. If your product is an industrial-grade product, then you need to choose industrial control chips and solutions. Instead of choosing a consumer chip solution. Some customers may choose low-performance solutions for cost reasons. Although the first year of use is no different from high-quality solutions.
However, after a long period of use, various problems may occur in the later period, and it may even become unusable. Just like industrial and medical equipment, many of them need to be exposed to harsh environments for a long time. They need to require a longer lifespan for capacitive touch screens. Therefore, if some suppliers give you a price that exceeds the average market price, then you have to consider whether their product quality can meet the standard. I think price is important for a project, but quality is also very important. Because only with high-quality products, a company can be highly praised and loved by customers and win the trust of more customers.
