Everyone knows that the working temperature of conventional TFT LCD screen is -20 to 70 degrees, the storage temperature is -30 to 80 degrees, and the working temperature of wide temperature TFT LCD screen is -30 to 85 degrees. In order to pursue a wider working temperature, some customers will test whether TFT LCD screen can work normally under extreme temperature. Many customers find that the words displayed on the LCD screen become very light when the temperature is very low, and the words become very dark when the temperature is very high. What's going on?

​The primary part of an LCD display is an LCD panel, or liquid crystal display. It is a flat panel with two glass panels layered on top of small liquid crystal cells. The crystals align and alter the amount of light that passes through them when an electric current is applied, creating an image that can be seen.

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.
