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.

Some customers are still not very clear about the resolution of the display screen. We will explain it here. The resolution of the LCD screen refers to the number of pixels of the LCD screen, that is, the number of dot matrix, which is usually the number of pixels in the horizontal direction multiplied by the number of pixels in the vertical direction. Under the same LCD screen size, the higher the resolution dot matrix, the clearer and more delicate the display image effect is.

Display and touch screen technology is becoming more and more mature, and there are many suppliers in the market.
