Do you buy an LCD Advertising Screen or an OLED Advertising Screen? They have two major differences!

In the current market, the major brands of billboards are also the pursuit of the Advertising screen material. Most of the screens are LCD Advertising screens and OLED Advertising screens. Some users think that the screen of OLED is better, and some users think that The LCD Advertising screen is better. So today we are talking about buying billboards to choose LCD Advertising Display or OLED? Many people are mistaken, they have two major differences! Let’s take a look.
The first difference: the screen display effect of the OLED is different from the screen display effect of the LCD. OLED's screen display color effect will be more vivid, higher saturation, LCD screen display color effect is relatively dark, mainly because it is not self-lighting, is issued by another backlight, so for this color The display is definitely different. Some users will think that the display quality of OLED will be much better, but some users will feel that such color saturation is too high, so that the color is somewhat distorted, not the color of the color itself, and this high saturation. The mobile phone is prone to visual fatigue for a long time, and now many users use the screen for a long time, so the screen material of the OLED will be more harmful to the eyes. Although the LCD screen material display effect is general, but at least for our visual impact is not so obvious, fatigue is not particularly serious, long time with the screen compared to the OLED screen, the LCD screen is better .
The second difference: the screen cost of the OLED screen and the LCD is different, and the life span is different. LCD screens are less expensive to produce, and OLED screen production costs are relatively high, so if the screen of the advertising machine is broken, the cost of repairing the OLED screen is much higher than the screen maintenance cost of the LCD. And the screen life of OLED is still relatively short.
Summary: In general, both have their own advantages and disadvantages.

Pleated vs. Wound Filter Cartridge – What’s the Difference?

Having the right type of water filtration system in your home is essential to keeping your water clean, fresh, and drinkable. One of the main problems that newcomers to DIY filtration face is choosing the right type of filter cartridge. There seems to be an endless number of factors to take into account: the size of the filter, its micron rating, the material it is made out of, and what substances it actually filters from your water. This week’s blog post compares two extremely common types of sediment filters: pleated filters vs wound filter cartridge. After reading, you should have a better idea of what type of sediment filter is right for your water filtration system. Let’s get to it!

The Basics
Sediment filters, as the name suggests, are used to remove excess sediment from water that passes through them. These filters do not remove any chemicals or heavy metals dissolved in the water and do not affect the taste or smell of the water, so make sure you have a sediment problem before choosing to use one of these filters.

When deciding on what rating to go with, there are two factors to keep in mind for sediment filters: the micron number and whether the filter is nominal or absolute. The micron number shows the smallest sediment particle the filter can trap. 1-micron filters can catch the smallest of particles, while 20- or 50-micron filters only catch the largest sediment particles. Nominal filters catch about 85% of particles that are the size of their micron rating or larger, while absolute filters catch 99.9% of those particles. The rating you choose to use is up to personal preference; it all depends on what kind of particles are present in the water. Filters that are excessively tight can lower water pressure, so its best to experiment a little to see which type is right for you.

Pleated Cartridges
Pleated filters, also called surface filters, are thin filters that catch sediment particles on their surface. These filters are made with a wide surface area that can hold a large amount of sediment particles. Pleated filters are typically used until their outer surface is completely covered in particles and then disposed of, but some high-end pleated filters can be reused. These filters work best when dealing with uniform-size particles. If all the particles are roughly 5 microns in size, an absolute, 5-micron pleated filter will work effectively and last a long time due to its wide surface area. If the particles vary in size, smaller particles will slip through the filter and larger particles will quickly eat up surface area.

String-Wound and String-Spun Cartridges
String-wound and string spun-filters are another effective way of removing sediment particles from your water. These filters are also called depth filters because they use 2 layers of filtration to keep out unwanted particles. The first layer catches any particles that are the same size or larger than the micron rating, while the inner layer catches smaller particles that slip through the initial filtration. This enhanced filtration comes at the cost of surface area, meaning that depth filters usually need to be cleaned/changed quicker than pleated filters. We find that there isn’t much difference between the string-wound and string-spun cartridges, so you are safe going with either kind.

Hopefully this article has given you a better understanding of common sediment filter types. It’s difficult to know exactly what type of filter you need without experimentation, so don’t worry if you don’t choose the right filter the first time.
