Waterproof Knowledge of LED Advertising Digital Signage

With the fast development of society, the application of LED digital signage is becoming more and more popular. However, the waterproof performance of a led panel is also a topic concerning every customer, especially outdoor led display screen. Do you have sufficient knowledge on the waterproof grade of the cabinet of the led display screen? Here the experts of Shenzhen D-King Photoelectric Technology Co., Ltd. will give us a brief introduction.

Generally speaking, the protection level of digital led signage is usually represented by IPXY, for example, IP65, X refers to the grade of preventing dust and debris from going inside, and Y refers to the closeness grade of preventing moisture and water. The bigger the number is, the higher the protection grade will be. Here we will introduce the meaning of the number after IP.

The meaning represented by X:
0: No protection
1: Prevent solid materials whose diameter is 50mm or larger.
2: Prevent solid materials whose diameter is 12.5mm or larger.
3: Prevent solid materials whose diameter is 2.5mm or larger.
4: Prevent solid materials whose diameter is 1mm or larger.
5: Prevent the accumulation of harmful dust (Cannot completely prevent dust from going inside, but the inside amount will not damage the equipment)
6: Completely prevent dust from going inside

The meaning represented by Y:
0: No protection
1: Prevent water drop. Water drops that fall vertically should not cause damage.
2: When the shell is inclined to 15°, it can prevent water drops, and water drops that fall vertically should not cause damage.
3: Prevent spilled water
4: Prevent sprayed water
5: Prevent water that is shooted onto the cabinet
6: Prevent strong shooted water
7: Can sustain soaking for short time
8: Can sustain soaking for long time under a certain pressure

Scanning Modes and Principle of LED Display Sign Screen

Inside a LED display sign screen, the ratio of the lines that are lit at the same time and the lines of the whole digital signage, is called scanning mode, which can be divided into 1/2 scanning, 1/4 scanning, 1/8 scanning and 1/16 scanning. It means that the driving method of the digital sign is different, which may influence the setting of the receiving cards.

For the receiving cards are to used in a 1/4 scanning led screen, if they are used in static led display screen, the display of the led advertising display board will have 4 lines of black intervals. Generally speaking, the receiving cards can be manually set, and when the customer successfully connects the main parts such as sending card, LED display sign and computer, he can enter the relevant software on the computer to set the receiving cards. Here the experts of D-King Technology will introduce the scanning modes and principle of LED digital signage.

1. Scanning Modes of Led Display Outdoor Advertising:

(1) Dynamic scanning: Dynamic scanning refers to that “pixel to line” control is carried out from the output of the driving IC to the pixels, and it needs control circuit and its cost is much lower than that of static scanning, but its displaying effect is not very good and the light loss is also huge.

(2) Static scanning: Static scanning refers to that “pixel to pixel” control is carried out from the output of the driving IC to the pixels. When static scanning is used, control circuit will be not necessary, and its cost is much higher than that of dynamic scanning, but its displaying effect is excellent, and it has such advantages as high stability and low light loss.

2. Working Principle of Led Advertising Board with 1/4 Scanning:

Every line of power V1-V4 starts for 1/4 time according to the control requirement inside the one frame picture. It can more effectively make use of the display feature of the led advertising signs and reducing the cost of hardware.

3. Classifications of Led Advertising Signs based on Scanning Mode:

(1) Indoor full color led display: P4 and P5 use constant current 1/16 scanning and P6 and P7.62 use constant current 1/8 scanning.

(2) Outdoor full color led display: P10 uses constant current 1/2 scanning, P16 and P20 use static scanning.

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.
