The concept and characteristics of outdoor high-brightness LCD screen

In the use of some outdoor equipment, due to environmental reasons, the brightness of the screen is usually very high. Such as handheld infrared thermometers, outdoor commercial screens, etc. This requires us to use an outdoor high-brightness LCD screen as the screen of the device. Next, we will focus on the concept and characteristics of outdoor high-brightness LCD screens.

1. The concept of outdoor high-brightness LCD screen

The so-called outdoor high-brightness LCD screen, as the name suggests, first of all, its brightness is higher than that of ordinary LCD screens. The maximum brightness of an ordinary LCD screen is within 500 nits, and the backlight is CCFL, so it cannot be seen clearly outdoors. The reason why the outdoor high-brightness LCD screen can be used outdoors is to increase the brightness of its backlight. With LED backlight, the brightness is similar to or even higher than outdoor brightness. Generally, it needs to be higher than 500 nits, and some can even reach 2000 nits of brightness, so that the outdoor LCD screen can display clearly. Secondly, due to the variability of the outdoor environment, to ensure that the screen can work normally under various environmental conditions, the outdoor high-brightness screen must also have functions such as wide temperature range, dustproof, and waterproof.

Second, the characteristics of outdoor high-brightness LCD screen

The outdoor high-brightness LCD screen has many advantages such as high brightness, high resolution, long life, wide temperature range, waterproof and dustproof. Of course, the most important feature is the high brightness, above 500 nits. The use of high-efficiency and energy-saving LED backlight modules not only greatly improves the brightness and contrast, but also greatly improves the display effect and service life. Therefore, it is visible and readable in outdoor sunlight, and the brightness range is large.

Secondly, resolution is also a very important indicator, referring to the number of pixels that the screen can display horizontally and vertically. High resolution can make the picture more delicate, allowing the screen to display more important information.

Wide temperature characteristics of outdoor high-brightness LCD screen. The outdoor environment is changeable, high temperature exposure, sub-zero ultra-low temperature. Therefore, the outdoor screen must have wide temperature characteristics, and the working temperature and storage temperature of the screen must reach -30°C to 85°C. Pay attention to the design of high and low temperature can reduce the failure of outdoor high brightness LCD screen.

Dustproof and waterproof performance of outdoor high-brightness LCD screen. In addition to the severe winter heat, there is also dust and water outdoors. The waterproof and dustproof of the outdoor screen is generally designed together with the whole machine, so special attention should be paid to the selection of materials to prevent water and dust from entering the screen.

At present, outdoor high-brightness LCD screens are widely used in aviation, ships, outdoor handheld devices, industrial embedded, large shopping malls, medical equipment and other fields. It has very high requirements on the screen itself, so the manufacturing cost will be much higher than that of ordinary LCD screens. Therefore, customers need to choose the appropriate screen according to their own products, so as to control the cost.
