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

First, it should be clear that the main type of radiation produced by LCD monitors is low-frequency electromagnetic radiation, and its radiation level is far below international safety standards. Compared with the old cathode ray tube (CRT) monitors, LCDs have much less radiation. Therefore, the impact of LCD devices on the human body is very limited. However, there are ways to reduce the impact of this radiation. In this article, we will explore some effective ways to reduce LCD screen radiation.

In addition, when designing the touch screen circuit principle, the grounding of the FPC cable can be increased, or the touch screen cable can be covered with double-sided black electromagnetic film, which can also reduce the electromagnetic interference problem of the touch screen in practical applications. Shenzhen Hongjia Technology has been professionally developing and producing 1.14-inch to 10.1-inch displays and supporting touch screens for 12 years. It has a R&D team of more than 20 people who are familiar with solving common problems in the industry and can reduce troubles for customers.

Backlighting is used in small, light, flat-panel liquid crystal displays (LCDs) and other electronic devices that require backlighting, including handheld devices as small as the palm of your hand, and large-screen TVs. The goals of backlight design include low power consumption, ultra-thin, high brightness, uniform brightness, large area, and control of different width and narrow viewing angles. To achieve these challenging design goals with controlled cost and rapid implementation, computer-aided optical design tools must be used for design. This article introduces the characteristics of LightTools optical design and analysis software from ORA Company in the United States, which can be used to develop the most advanced backlight design applications today.

In order to meet the stringent environmental temperature requirements of different customers and different product applications, our company has launched a variety of ultra-low temperature LCD screens. The operating temperature can reach -30 to 85 degrees, and the storage temperature is also -30 to 85 degrees. The wide-temperature LCD screen has picture It has the characteristics of stable quality and adaptability to harsh environmental temperatures, and can be widely used in military, telecommunications, electric power, metallurgy, machinery, CNC, petroleum, chemical industry, medical, aerospace and other fields.

Another advantage of using a 3.4-inch round TFT screen is that it is compatible with both RGB and MIPI interfaces. RGB interfaces are commonly used in consumer electronics, while MIPI interfaces are popular in mobile devices. Shenzhen Hongjia Technology produces 3.4-inch round TFT screens that can support RGB interface support 16/18/24 bits; also supports MIPI interface support 2/3/4 channels. This compatibility allows for easy integration with a variety of products, making it a versatile choice for many different applications.
