The effect of temperature on the Cold-resistant display
Outdoor high-brightness LCD screen is a common outdoor media method. Generally, high-brightness LCD screen is selected for outdoor display. However, the outdoor environment is not as good as the indoor constant temperature environment, and the outdoor generally faces severe temperature difference and other harsh conditions. envirnmental factor.
The working temperature is particularly important outdoors. The outdoor industrial display screen is made of high-temperature resistant materials, which can achieve normal display without black screen at high temperature of -86°F~230°F, which is enough to face extreme outdoor temperature problems. The special properties of working in high temperature environment.
The general working temperature of commercial display LCD screens used in ordinary indoors is in the range of 0~122°F. If the temperature exceeds this temperature, a partial blackening reaction will occur on the screen, which will greatly limit the use experience of the screen in an outdoor working environment. , The outdoor high-brightness industrial cold-resistant display is specially customized for the outdoor high-temperature environment, realizing the characteristics of normal operation in the ultra-high temperature environment with the extreme temperature of 230°F, and can meet the industrial display screen used in any outdoor scene.
The effect of high temperature on the Outdoor LCD Display
What is the effect of high working temperature on LCD panel? Today, WIECOO LCD screen manufacturers share with you how high working temperature will affect the LCD strip screen: Excessive temperature will have devastating damage to the LCD screen:
1. Liquid crystal displays are usually encapsulated with silicone. If the operating temperature exceeds the solid phase transition temperature (typically 257°F), the encapsulation material will become rubbery and rapidly expand thermally, resulting in open circuits and Cold-resistant display panel failure.
2. If the operating temperature of the LCD screen exceeds the maximum bearing temperature of the chip, its light-emitting rate will drop rapidly, resulting in light attenuation. The lifespan of an LCD display is reflected by the attenuation of light, that is, the brightness of the LCD screen decreases over time.
The reason why temperature affects the luminous rate of LCD strip screen:
1. As the temperature increases, the concentration of electrons and holes increases, the band gap decreases, and the electron mobility decreases.
2. High temperature will cause the blue light peak of the chip to move to the long-wave direction, so that the wavelength of the chip does not match the wavelength of the phosphor, thereby reducing the light extraction efficiency outside the liquid crystal display.
3. As the temperature increases, the quantum efficiency of the phosphor decreases, the luminescence decreases, and the light extraction of the liquid crystal display decreases, resulting in a decrease in the brightness of the liquid crystal display.
4. The shape of silicone products is greatly affected by temperature. As the temperature increases, the internal heat of the silica gel increases and the refractive index decreases, resulting in an increase in the light efficiency of the liquid crystal display.
To sum up, it can be concluded that a reasonable and appropriate temperature is the key to the clear outdoor LCD display panel. The strip-shaped smart LCD strip screen will be attached with a work manual at the factory. Users can use it normally as long as they follow the instructions.

Cold resistance of the Outdoor LCD Display
LCD advertising machines are also resistant to cold, you know? Anyone who has observed life carefully at ordinary times knows that once it snows or the temperature is below zero, roadside advertising signs, outdoor LCD Display advertising machines in bus stations, etc. will cause “condensation” and other phenomena due to the large temperature difference between the inside and outside of the advertising machine, and even some. Advertising opportunities stopped working because they couldn’t tolerate low temperatures. So, in addition to daily diligent maintenance, how can we completely say “NO” to these problems?
If you want to really solve the problems of these trivial matters, the choice at the beginning is the focus. If you choose a high-quality outdoor LCD display advertising machine that is not afraid of cold, winter and heat, it will not only save money but also worry. Among the brands in the digital signage industry, the WIECOO outdoor LCD advertising machine can truly withstand the cold and heat.
The clear outdoor LCD display advertising machine is equipped with the domestic advanced intelligent cooling and heating integrated air conditioner, which always keeps the body itself at -100-+120℉, which can operate normally regardless of the harsh summer or the coming winter. At the same time, it has passed a series of high-temperature aging, low-temperature aging, and simulated sunlight tests, and enjoys temperature control with patented technology, so that the backlight brightness of the clear outdoor LCD display will not be attenuated even if it runs for a long time, and it will not fade under direct sunlight. blackening phenomenon.
In addition to the above features, the clear outdoor LCD display advertising machine also applies an intelligent monitoring system to monitor the internal environment of the machine at any time. The sealing and anti-corrosion technology allows the outdoor LCD advertising machine to easily adapt to any external bad weather. Even in heavy rain, sandstorms, and heavy snow, it can always remain clear and beautiful.
