How to solve the electromagnetic interference problem of small and medium size touch screen

With the increasing popularity of the Internet, all kinds of communication devices are becoming more and more popular among consumers, which leads to a sharp increase in the demand for data transmission. In addition, digital TV, high-definition TV, and color images all require higher bandwidth. Therefore, system design engineers must rely on analog technology to design circuit systems and support data transmission. Low-voltage differential signaling (LVDS for short) is one such analog technology that engineers can use to design mixed-signal systems. LVDS uses high-speed analog circuit technology to ensure that copper wires can support data transmission above gigabits.

A 4.0 inch Round LCD module is an electronic display component that provides a clear and high-resolution visual output. Here are a few reasons why you might need this module:

IPS is the abbreviation of In-Plane Switching in English. The English meaning is in-plane switching hard screen technology, commonly known as "hard screen". It is the most advanced LCD panel technology in the world. Like wearing glasses. Generally, more mainstream mobile phones will use IPS screens, which have excellent display effects, so it has become one of the major selling points of many mobile phones.

First of all, the advantage of incell LCD screens is that they are thinner and lighter than traditional TFT displays because they integrate the touch sensor and display layer into a single layer. Traditional TFT LCD screens require external mounting to fit the touch screen, which increases the thickness. In addition, the touch screen also requires a separate design of a cable, which will occupy the space inside the machine. Incell LCD screens only need to be attached to a layer of glass cover to form a complete LCD touch screen assembly, which makes them ideal for portable devices such as smartphones and tablets. The reduction in thickness and weight makes the design more compact and stylish, which is very important for the trend of thinner and more portable devices.
