Capacitive touch screen is the most popular product in the display industry, which has been fully used in electronic products such as mobile phones and tablet computers. Scrolling, zooming and pinching, these incomparable experiences are what we don't have when we use a resistive capacitive screen.
In the field of industrial display, capacitive touch screen has been greatly developed in recent years. Different from consumer products, the operating environment of capacitive touch screen is more extensive and harsher, which puts forward a great test to the performance. The capacitive touch screen we design and produce is mainly based on G+G structure, which is more stable and more suitable for matching industrial display. Therefore, our cover lens is usually made of glass. Next, we will introduce several important points of capacitive touch screen in the field of industrial display in detail.
I. Controller of Capacitive touch screen:
For capacitive touch screen, it is crucial what functions that controller can achieve. Usually, the life cycle of capacitive touch controller for consumer products is short, they have a strong bias, often need to optimize the cost, as the market demand changes, these capacitive touch controllers will face revision or stop production, their life cycle may only be 2-3 years. Regarding the capacitive touch controller for industrial display, we care more about the powerful performance and the continuation of life. This means that a driver IC can go for as long as a decade or more without making any changes. This is what the industrial display field needs and what the industry wants. Once the development is complete, your product does not need to change anything in the future.
2、Communication interface:
In the field of industrial display, capacitive touch controllers are generally communicated by I2C and USB interfaces. We can also provide you with both interfaces on the same product. USB may be directly compatible with windows and Linux systems, which will save a lot of development time.
3、Electromagnetic compatibility and ESD:
IEC CI/CS test level (conduction tests, standard grades 1-3, 1V, 3V, 10V)
ESD test level (air discharge/contact discharge, KV)
EMI test level (EMI Peak level, Average Level)
4、Gloves and touch with water:
The environment of industrial display is relatively harsh, and sometimes workers need to wear gloves to operate, in this case, the capacitive touch screen must support glove mode. There are many kinds of gloves, such as medical latex gloves, relatively thick rubber gloves and cotton gloves. We will adjust software according to the use condition and the operating environment. In industry field sometimes there will be water mist or water droplets on the screen surface, such applications can also be handled perfectly, we have the corresponding touch function with water.
