A. power supply

The power of all mobile devices can not be separated from the supply of energy, and lcd advertising machine display screen is no exception.

The power supply is the pillar to support the content broadcast in lcd advertising machine display screen, so it is very important to choose a stable and high-quality power supply.

If you buy a product from a certified manufacturer, you don't have to worry about power supply at all during the service life of the product, and the service life can reach 10 to 15 years.

B. LCD screen

The most important part of lcd advertising machine is the LCD screen. If the power supply is likened to a supply line, then the display screen is a tall image of a general fighting in front, a handsome soldier and a foreign country. It is an important way of advertising communication, so the LCD screen must pass the performance test.

Generally, the service life of LCD screen is 6 to 10 years. Although the service life of LCD screen can be extended by replacing the lamp tube, the aging of LCD screen will still affect the picture quality of advertising machine. If it is a lcd advertising machine produced by a regular company, it will all adopt a brand-new imported LCD screen, and it will never use an old screen, an old screen or a dot screen. When choosing, we must pay attention to prevent the merchants from shoddy and appearing dark spots, color spots and blue screens.

C, decoding function of decoding board chip

Lcd advertising machine's third key is the support, resolution and stability of the decoding function of the decoding board chip. The supported formats of general advertising machine display screens can decode videos and pictures in common formats.

The main difference lies in the display effect and stability when playing files. Finally, there is the appearance of lcd advertising machine products.

It is very important to choose products with beautiful appearance on the basis of the same price, and customers are more acceptable to have an eye-catching lcd advertising machine display screen.

These are the three points that Ruiguan explained to you that a high-quality outdoor lcd advertising machine display screen should meet.

In fact, many customers will consider the price when choosing, and may give priority to the low price, but the lowest price is likely to bring the greatest loss. Low-priced advertising machines seem to be the same on the surface, but there are great differences in advertising machine display screens: low-grade screen, low-capacity motherboard, low expansibility, low function and low compatibility.

Low guarantee service index will make you have unlimited troubles in future use: frequent crashes, flashing display screens, and even failure to turn on the machine.

Therefore, high-quality outdoor lcd advertising machine display screen should meet the above three points.

Ruiguan hereby warns that when choosing outdoor lcd advertising machine display screen, the above three points must not be ignored except considering the price.
