Discover the advantages and disadvantages of capacitive touch screens and resistive touch screens

Now, there are so many electronic products around us, mainly because these electronic products can facilitate our lives, so there are many touch screens appearing around us now. For this wide variety of electronic products, we must first understand its specific performance before use, to grasp more information, so that we do not have any problems during the use of the process. According to Xiao Bian, capacitive touch screens have the following advantages over traditional resistive touch screens:

1. Operation novelty: Capacitive touch screens generally support multi-touch, the operation will be more intuitive and more interesting.

2. It is not easy to touch: Because the capacitive touch screen needs to sense the current to the human body, only the human body can operate it and will not react when touched with other objects, so basically it avoids the wrong touch. possibility.

3. High durability: Compared with resistive touch screens, capacitive touch screens are better represented in all aspects such as waterproof, dustproof, and abrasion resistance.

As the mainstream touch screen function, capacitive touch screens have various advantages such as multi-touch, rich interface, and human sensing. At the same time, however, it also has the following defects:

1. Accuracy is not high: Due to its function, the accuracy of capacitive touch screens is still short compared to resistive touch screens. And can only use the finger to input, on the small screen is still difficult to recognize more complex handwriting input.

2. Easy to be affected by the environment: When the environmental factors such as temperature and humidity change, it may cause instability and even drift of the capacitive touch screen. For example, when the user is in use, moving the body closer to the screen together may cause drift, and even operating in crowds may cause drift. This is mainly due to the operating principle of the capacitive touch screen technology. Although the user's finger is closer to the screen, there are still many electric effects in the vicinity of the screen that are much larger than the finger's. This will also affect the judgment of the contact position. .

3. The cost is high: Beyond this, at the time, the capacitive touch screen had certain technical difficulties in the process of attaching the touch panel to the LCD panel. The yield rate was not very high, so the capacitance was increased invisibly. Touch screen costs.
