For film panels for outdoor use, the following characteristics are required:

First, weather resistance

In the outdoor environment, the ultraviolet rays in the sunlight will cause damage to the film panel, causing its color to fade and the material to age. Therefore, outdoor film panels need to have good performance and can withstand ultraviolet radiation for a long time without changes.

The capacity of the film panel can usually be improved by adding ultraviolet absorbers, using ultraviolet resistant materials, and so on.

High and low temperature resistance:

The outdoor temperature changes greatly, and the film panel needs to be able to work normally under different temperature conditions. In high temperature environment, the panel can not be deformed, softened or lose viscosity; At low temperatures, it cannot become brittle, crack or lose elasticity.

The selection of materials with good high and low temperature resistance, such as special polyester film, polycarbonate film, etc., can meet the temperature requirements of outdoor film panels.

Waterproof and moisture-proof:

In the outdoor environment, the film panel may be eroded by rain, dew, etc., so it needs to have good waterproof and moisture-proof performance. The surface of the panel should be able to effectively prevent water penetration, and the internal circuit should also be waterproof to ensure normal operation in a humid environment.

Waterproof coating and sealing structure can be used to improve the waterproof and moisture-proof performance of the film panel.

Ii. Durability

Wear and scratch resistance:

Outdoor use of the film panel is vulnerable to friction, scratching and other external forces, so it needs to have a high wear resistance and scratch resistance. The surface of the panel should be resistant to wear in daily use, and not easy to scratch and damage.

The wear resistance and scratch resistance of the film panel can be improved by using materials with higher hardness and adding wear-resistant coatings.

Chemical resistance:

There may be various chemicals in the outdoor environment, such as acid rain, cleaning agents, etc., which may cause corrosion to the film panel. Therefore, the outdoor film panel needs to have a certain chemical corrosion resistance and can resist the erosion of common chemicals.

The selection of chemical corrosion resistant materials, such as polytetrafluoroethylene film, can improve the chemical corrosion resistance of the film panel.

Impact resistance:

Outdoor film panels may be subject to accidental impact or impact, so they need to have a certain impact resistance. The panel should be able to avoid breakage and damage after a certain degree of impact to ensure its normal use.

The impact resistance of the film panel can be improved by increasing the thickness of the panel and using elastic materials.

Iii. Readability

High contrast:

In the outdoor environment, the light is strong, and the film panel needs to have a high-contrast display so that the user can clearly see the information on the panel. You can improve the contrast of the panel by choosing the right color combination, using a high-brightness backlight, and so on.

Anti-glare:

Direct sunlight or reflection may cause glare in the film panel, affecting readability. Therefore, outdoor film panels need to have anti-glare performance, and the impact of glare can be reduced by using anti-glare coatings and adjusting panel angles.

Good viewing Angle:

The outdoor film panel needs to be clearly seen by the user at different angles, so it needs to have a good viewing Angle. The viewing Angle of the panel can be improved by optimizing the structure design of the panel and selecting the appropriate display technology.

4. Reliability

Stable electrical performance:

Electronic components in outdoor film panels need to have stable electrical properties and be able to work properly under different environmental conditions. For example, the parameters of components such as resistors and capacitors should be within the specified range, and are not affected by factors such as temperature and humidity.

High-quality electronic components and rigorous electrical testing can be used to ensure that the electrical performance of the film panel is stable.

Strong connection:

The various components in the film panel need to be firmly connected to ensure that there will be no loosening, falling off and other problems in the outdoor environment. For example, the connection between the key and the film circuit should be reliable and not fail due to frequent pressing.

Welding, hot pressing and other methods can be used to achieve a strong connection.

Outdoor film panels need to have a long service life and be able to work continuously under harsh environmental conditions. Thin film panels can be improved through the selection of high-quality materials and strict quality control.
