Selection of Led Advertising Display Board for Supermarket

How should a supermarket choose suitable led advertising display board? A supermarket should choose according the features of led advertising display board and the actual needs of customers. Generally speaking, advertising digital signage used for supermarket should have such advantages as clear font, low price and fleet control.

The led advertising display screen used for supermarket is mainly used for displaying advertising promotion information, and mainly displays words information, so it usually requires low price, for this reason, P10 outdoor digital signage and semi-outdoor digital signage can be chosen. If high displaying effect is required, indoor P5, P6 and P7.62 full color led display and outdoor P10 and P12 full color led can be chosen.

In addition to the factors of price and models of the led billboard, the following aspects should also be considered:

(1) Brightness

For indoor general illuminance environment, indoor led display is recommended, and for outside use, the outdoor led display board is more suitable. And for the environment with strong sunshine such as spacious hall, eave, outdoor canopy or under the roof, semi-outdoor led billboards are recommended.

(2) Displayed content

If needs to display images and video, a full color led display should be chosen.

To display words, data, table, three-dimensional figure and animation, biradical colorful grey level display panel needs to be used.

To display words, data, table and two-dimensional figure, double-color led billboard display needs to be chosen.

To display words, data and table, single color led billboard signs can be used.

(3) Information capacity and visual distance

When choosing a led display board, the information capacity and optimum visual distance should also be considered. The content that can be displayed by a curved led display is unlimited, but the content that can appear on one picture is limited. Besides, every model of led display panel has its own optimum visual distance.

The Composition of the Price of Led Digital Display Board

As for many non-professional users, they may not know which one to choose facing the quotations offered by led digital display board manufacturers. In fact, it will be easy to choose as long as knowing the composition of the price of the digital display board.

1. Cost of LED display board

A led display board is mainly composed by led module, power supply, cabinet, flat cable and power cables, among which, the cost of led module is the highest; and the difference in price of the LED and chip is also huge. Generally speaking, the price of the led display board will account for over 70% of the total quotation, and indoor full color led display board may have higher price due to higher pixel density.

2. Control system

Led full color display board usually uses synchronous display system which is composed by sending card and receiving card. For an outdoor led display smaller than 80 square meters will need one sending card and about 80 pcs of receiving cards.

3. Accessories

To be able to work normally, led electronic signs will need many accessories such as computer, air conditioning, lightning arrester, power distribution cabinet, AMP, TV card, multi-function card and video processor. The price will be different for different brands, and customers can purchase the accessories at local place.

4. Steel structure

An outdoor led display panel will need a steel structure for fixation. Especially for outdoor large led advertising display board, it will have very high requirement for the steel structure. The cost of steel structure ranks only second to the led display screen.

5. Transportation and installation

After learning such basic knowledge, customers can ask for a full quotation when faced with different suppliers to avoid some suppliers forcing downing the price by reducing or bringing down the accessories.

Quality and Parameters of Dedicated LED for Full Color Led Screen

1. Failure rate

One full color led display is composed by over ten thousands and even hundreds of thousands of pixels consisting of Red, blue and green three LEDs, and the failure of any color of led will influence the overall displaying effect. Generally speaking, according to the industrial experience, the failure rate of the led panel display from assembly to the aging process of 72 hours should be lower than 0.03%.

2. Anti-static ability

As a semiconductor device, the LED light is very sensitive to static electricity, and it can easily cause the static electricity to lose efficacy, for this reason, the anti-static ability is paramount for the service life of the led display rentals. Generally speaking, the failure voltage of the human body static mode test of the led light should be no lower than 2000V.

3. Fading feature

The brightness of the three color led lights will fade along with the increase of working time, and the quality of LED chip, quality of the supplemental material and the encapsulation technical level will decide the fading speed.

4. Brightness

The brightness of the LED is an important decisive factor of the brightness of the electronic message board signs, and the bigger the margin of the used current is, the more goodness it will bring to save electricity consumption and stabilize of the led display screen. LED lights have different angle values, and under certain chip brightness, the smaller the angle is, the brighter the LED will be, and smaller the visual angle of the led wall display will be.

5. Consistency

Since a full color led wall display is assembled by the pixels composed by many red, green and blue LED lights, the brightness of every color of LED light and the consistency of the wave length will decide the consistency of brightness, white balance and color scale of the whole video display wall.
