With the rapid development and progress of science and technology, the scope of application of touch display is more and more extensive, not only for indoor TVs, computers, etc., but also for outdoor use as large display screens or advertising screens. Since the outdoor touch display needs to adapt to the complex environmental changes, it will face severe challenges in terms of screen brightness, color, waterproof and dustproof, and heat dissipation capacity. Today Top One Tech will talk about it from five aspects, hoping to brings new directions and opportunities for the development of outdoor touch display, and it can also provide useful information as a reference for customers who purchase a touch display.
1. The problem of outdoor temperature
The first challenge faced by the normal use of outdoor touch display is the extremely cold temperature environment, especially in countries and regions located in high latitudes, the minimum temperature can reach -50 ℃ ~ -20 ℃, so it is necessary to ensure that the touch display’s components will not be short-circuited by the weather.
2. Outdoor waterproof and dustproof protective shell
One thing to note here is that the protective casing of the touch display is specially made, not only needs to be waterproof and dustproof, but also needs to prevent the influence of various factors on the display, such as ultraviolet rays, corrosion, electromagnetic radiation, etc., in different regions, it needs to be comprehensively considered according to different use requirements, then can we choose the best protection mode of the outdoor touch screen.
3. Day and night brightness adjustment
During the day and night, the brightness of the touch monitor is adjusted according to the different needs of use, so as to achieve the best use standard while reducing power consumption as much as possible, and finally achieve the purpose of energy saving and emission reduction. At present, LED backlight technology is mainly used to adjust brightness and color, and its service life, color brightness, and clarity meet the needs of use, laying the foundation for the technology of day and night brightness adjustment of LCD screens. However, there are currently new requirements for the use of outdoor touch displays , such as anti-vibration performance, anti-dizziness performance, reducing the brightness and color difference of the LCD screen, and reducing the mirror reflection effect of the screen.
4. Heat dissipation problem
The hot issue that every outdoor touch monitor needs to face is the heat dissipation problem, and the cost is high. The installation cost of air conditioner cooling is too high and unbearable, especially in hot summer, it is difficult to meet the needs of heat dissipation only by relying on fans. Therefore, it is necessary to adjust the cooling system and air duct design of the outdoor touch monitor to achieve better heat dissipation.
