Reason：

1. Ebony uses a larger chip to achieve greater brightness.
2. Adopting black bottom filling technology, there is no coating on the surface, which reduces the impact on brightness.

Benefit：

1. High brightness 2000cd
   Ebony uses a larger chip for greater brightness
2. Color reducibility
   Compared with the conventional COB, there is no covering film on the surface, and the color is more restored to the original color of the chip
3. High contrast
   Multiple correction technology and pure black and high limit brightness to achieve ultra high contrast

Because of the use of underfill technology and the use of large-size chips 4µm x7µm, the brightness can reach 2000 luminance, and the cost is increased.

Because the chip used by SHISAI has a single side length of less than 50um, an area of less than 2500um, and no sapphire substrate.

4.Similar to indoor image quality, it can be used outdoors

The high image quality and high contrast effect of indoor small spacing display is also suitable for outdoor display.

5.Supports multiple spacing sizes

The spacing size ranges from 0.9 mm to 2.6 mm, which can meet the needs of various applications.

The longer the single module is, the voltage will decay, resulting in lower brightness.

• Price：SHISAI holographic screen has a more favorable price and a higher cost performance.
• Length：SHISAI holographic screen products can be configured with longer lengths.
• Mask tech：Use advanced mask technology to extend product life
• Multiple option：You can choose between IC separation and IC integration versions.

• Advertising LED wall displays typically are made with a higher brightness capacity than everyday LED TVs or mobile screens. They need to be viewable from much larger distances at the highest point of daylight and the darkest night. This brightness is measured by using nits or candelas per m2. More luminosity is equal to greater brightness.
• LED wall displays with greater brightness capacity indeed tend to be a bit more expensive and use more electrical power, but if you find an LED panel manufacturer like SHISAI with specialized equipment and years of experience, you can often lower that cost a bit because of the advanced technology they use for production.

You are going to want to select your final LED wall display based on the amount of brightness it can produce given the unique positioning you plan on using the screen for, including:

1. LED Lamps

The type and quality of the LED lamps are the most direct factor of brightness. LED lamps with large chips are generally brighter accordingly, and good quality lamps can keep bright at a lower voltage.

2. Scan Rate

The scan rate of the PCB board will directly affect the screen's brightness. Among them, the static scan is the highest value, which is 1 scan. The number of scans can be designed for different applications of LED wall displays. All other things being equal, the higher the scan rate, the lower the brightness.

3. Pixel Pitch

Pixel pitch is another factor influencing brightness. When the number of scans and the quality of LED lamp is at the same level, the smaller the pitch, the higher the brightness. This is because LED wall displays have more light-emitting units per unit square. However, as different dot pitches corresponding to the number of scans will be different, it is no need to focus much on the pixel pitch while considering the screen's brightness.

4. Module Power Supply Voltage

Generally speaking, the voltage set by the factory will also affect the brightness. However, the manufacturer will set the power supply voltage considering the service life and heat generation.

Any quality LED wall display will have customizable features that result in higher quality brightness. It can be solved at the manufacturing level by working directly with the individual company responsible for your product. You can configure a brighter screen:

1. The manufacturer should use high-quality, suitable, larger chip lamp beads; high-quality LED lampscan withstand the current better while the brightness is more durable.
2. The use of a relatively low scan rate can significantly increase the screen's brightness. However, the cost of the screen will also increase accordingly.
3. The manufacturer is required to adjust the current gain. Within a certain range of values, the screen's brightness can be increased by adjusting the current gain. However, if the current gain is adjusted too high, it will increase the possibility of screen heating, accelerate the decay of LED lamps and shorten the life of the screen. Some irresponsible manufacturers on the market will make the screen parameters better by adjusting the current gain a lot, damaging the screen. Therefore, you need to choose a reliable and experienced manufacturer.

1. Products structure of 5G solution

2. 5G has higher load capacity and faster transmission speed.

•  A single cable supports 2.9 megapixels, four times the performance of traditional 1G solutions. This not only allows more cabinets to be supported, but also significantly reduces the number of Ethernet cables. Faster data transfer speeds also make field parameter uploads and file transfers more efficient.
• The adoption of 5G solutions can significantly reduce cabling and installation time and reduce labor costs.
• Note: The cable must comply with the CAT6A standard.

3. When the number of LAN cables increases and management becomes difficult, the 5G will be recommended in this case.

4. For example, 8K LED screen 1G and 5G system structure comparison

-It can maintain excellent load capacity even at high color depth

• 8-bit @ 60Hz: 2,951,200 pixels
• 10-bit @ 60Hz: 2,213,200 pixels
• 12-bit @ 60Hz: 1,475,600 pixels

-Minimize the number of cards and processors Reducing the number of devices improves system reliability and reduces the risk of field failures.

-The MX6000 Pro supports up to 16K resolution (141 million pixels) and can manage a large screen from a single device.
-Provides 8K input interface to avoid signal division and cascaded distortion problems.

5. Analysis of core value points of COEX 5G solution

• With the popularity of ultra HD media, the demand for super large LED displays is growing rapidly. However, the traditional 1G control width transmission faces many challenges, complicated cables and equipment and complex system structure bring burden to the project.
• NovStars innovative 5G solution is here! NovaStars offer multiple processors based on project size (4K to 8K, even 16K). There are two types of receiver cards: CA50E and XA50 Pro.

• You want to maintain your LED advertising screen display because you are using it to increase online and in-person traffic with your business. For example, consider the displays at major intersections like Times Square in New York City, USA. These advertise everything from upcoming Broadway shows to notable brands viewable from great distances.
• As many commercials and user-generated content are created around these giant screens, you need them operating at their most efficient capacity at all times. Unfortunately, it also lowers operating costs as you won't have to spend resources improving, repairing, or replacing such large advertising wall displays.

There are a few significant points you need to keep in mind to improve the lifespan of your recently acquired advertising display, including:

1. Heat

Heat or extreme temperatures can warp or damage your LED screen display without proper consideration. It would help double-check that the LED display supplier you are using has excellent heat dissipation components installed in the products.

2. Weather

If any water gets inside the sealed LED screen, it will damage the screen and probably replace the entire advertising screen display. Double-check that all the products you consider have excellent waterproofing and even screen features that prevent possible hail damage.

3. Sunlight

Even with the best anti-glare/reflective surface, your LED advertising screen display is likely not to be fully functioning under direct sunlight. Be sure to mount it with the arc of sun exposure under consideration and the proper brightness factor when purchasing.

4. Internal Components

Only work with an expert supplier like SHISAI that uses high-quality internal components from heatsinks to voltage controllers, so you know these will perform to their proper capacity and leave little room for maintenance requirements.

Here are several more common tips we've found helpful for maintaining your LED advertising screen display indoors or outdoors.

1. Power On/Off

Try to keep the screens off for at least 2 hours a day so they can be properly cooled down. If you don't need them all that often, turn them on at least once per week to keep the components' properties prepared for more prolonged use.

2. Power Supplies

Always provide stable power to the advertising screen display and use a surge protector to ensure no unwanted charges make it through to the LED components. If the screen is found to have a short circuit, tripping, smoke, and other abnormal appearances, you should not use power repeatedly on the test. Instead, you should promptly contact professional maintenance personnel to troubleshoot the problem.

3. Cleaning

Whether indoor or outdoor LED display, it will accumulate a certain amount of dust after a period of use. The surface of the LED display screen can be wiped with alcohol, or use a brush or hoover to remove dust, not directly wiped with a wet cloth.

4. Moisture/Storage

Store your advertising screen display in a cool, dry place that isn't resting on the floor. Even though these are designed to be waterproof, you don't want to expose the device to heavy moisture or humidity.

5. Regular Inspections

These are expensive devices that you do not want to waste time, money, or human assets to replace. Have a regular schedule of inspections to ensure the screens are always functioning properly.

The LED display is prone to color differences, such as shaded colors. It means that the display will cause regular differences in light and dark while viewing at different angles, which seriously affects the visibility and experience of the display.

LED Lamps, Circuit Design and Quality of PCB Board, Power Supply, Control System and IC Driver, Welding Process will all cause color difference of LED screen.

Cause: 

1. The LED lights of the same advertising screen display come from different batches. Some LED screen manufacturers mix different batches of LED lights while producing the same LED screen for they might not have enough lights or storage. However, these different batches of LED lights will produce distinct color differences due to time length.
2. LED lamp wavelength range is large, and the mixing process is not good enough. It depends on the LED package supplier's process level and the quality of LED lights.

Solution: 

1. The LED display should be made color calibration and save the calibration data. It is the most common and effective method, but losing a certain degree of brightness is the disadvantage.
2. Choose a high-quality lamp package supplier.
3. Should prepare enough modules of the same batch.

Cause:

1. The unreasonable circuit design of the PBC board will cause varying degrees of color difference or color underperformance of advertising screen displays. Some poor quality PCB boards reduce some electronic components to cost savings. These boards have fewer layers so that the lines will be denser. The advertising screen display made by these PCB boards with weak heat dissipation performance will directly produce color differences.
2. PCB board material and the number of layers impact the screen's performance. It is easy to cause color display deviation, temperature drift, especially when the temperature is high.

Solution: 

1. Purchase the PCB boards from trustworthy manufacturers.
2. Require PCB suppliers to offer PCB boards with reasonable PCB board layers.

Cause: 

1.  Low-quality power supply has a low conversion rate, and the same power supply needs to consume higher power, thus increasing the screen temperature.
2. Low-quality power supply may have an abnormal voltage supply, thus producing color difference.

Solution: 

1. Advertising screen displays should be used with a stable quality power supply.
2. Install fans or AC for the screen if possible.

Cause: 

The IC driver is the nerve center of the whole LED display, and it controls the whole performance of the LED advertising screen display. The processing channel current of low-quality IC driver is not precise enough, resulting in poor color expression.

Solution: 

LED screen manufacturers should choose suitable IC drivers from trusted IC driver brands.

Cause:

Bad soldering of electronic components can lead to regional color differences, and it is a problem that exists on any component with a circuit board.

Solution: 

1. Choose a trustworthy manufacturer with good artistry and strict quality control.
2. Do not miss the aging time of the product.

Various problems cause color differences in screens, so choosing a reliable led screen manufacturer is important. We at SHISAI are committed to providing our customers with a variety of screens of consistent quality.

The IP rate is created as a waterproof standard for the goods to provide users with more detailed information. Likewise, it is also suitable to identify the waterproof capacity of the outdoor LED display boards.

• Code letters: IP (Means Ingress Protection)
• First characteristic numeral: Single numeral 0-6 or letter X (Means solid particle protection)
• Second digital: Single numeral 0-8 or letter X (Means liquid ingress protection)
• Third digital: Single numeral 0-9 (Means mechanical impact resistance)
• Additional letter: Single letter (Means other protections)
• Supplementary letter: Single letter (Means other protections)

From the information shown above, it is not difficult to find that IP65 meets most outdoor LED display cases. But one thing that could not be ignored is the waterproof capacity of outdoor LED display board may change as it is always exposed to the outdoor environment like distortion, oxidization, corrosion, etc. And all these are closely relative to the manufacturing process and materials. Moreover, the waterproof of the outdoor LED display board should be viewed respectively.

• LED Module: 

1. Common module with rear exposed but coated

Mostly we meet this kind of module from the outdoor LED display with conventional cabinet. The key point of waterproof performance of the LED display is the cabinet and module fixing; the coating is the last step of defense instead.

2. Sealed module with pin interface:

This module mostly works with the die-cast panel or independent power room. It is the silicone ring at the interface which offers waterproof. Therefore the magnetic module of this type is not recommended for DOOH.

3. Sealed module with waterproof plug:

It is a relatively better module for an outdoor LED display board with excellent waterproof capacity, but the cost may be higher.

• Power room:

1. Integrated power room:

The power room in Ivory series  is just the whole cabinet. But SHISAI's LED display screen leaves a shutter on the backside, which leads to this type reaching only IP54.

2. Independent power room:

The waterproof capacity generally depends on the silicone ring and connectors.

• Plug and connector:

Selecting a good-quality connector is the best way to ensure the LED display is waterproof.

Generally speaking, a waterproof display doesn’t just rely on simple IP rate specifications. Instead, it is consist of design, materials, manufacturing process.

The viewing angle of the LED wall display is an important indicator to measure the display effect and quality of the screen. There are two definitions of viewing angle. One is the angle where the brightness drops to half, and the other is the angle where the image is still recognizable and there are no visible shadows. It is generally expressed as the horizontal angle and vertical angle. The following will introduce this parameter in detail:

• Horizontal Angle

The horizontal viewing angle of the LED display screen refers to the maximum angle from which a normal view can be seen on a plane perpendicular to the display surface. If you are looking at a straight LED display, when your eyes move horizontally, you will find that the color on the screen will be distorted and eventually become black. The maximum horizontal viewing angle of humans is generally between 160°.

• Vertical Angle

The vertical viewing angle (or tilt) refers to the maximum angle from which a standard view can be seen on a line along the center of gravity of the display surface. The viewing angle is an important indicator of whether the display device has immersive visual effects – significant for LED dot matrix display devices. The maximum vertical viewing angle of an LED wall display is 140°.

• The viewing angle of an LED display is essential, especially for outdoor LED display boards. The smaller the viewing angle, the brighter and more colorful your screen will appear from those angles. It can distinguish between a legible sign and one that looks like a blur of color when viewed from an angle. The viewing angle can make a significant difference in enhanced user experience.
• The viewing angle of an LED display determines how the audience perceives a certain display. For example, installing a large outdoor LED screen as a video wall or billboard will require a wide viewing angle LED display. However, installing an indoor LED screen for a control room or studio will require a narrow viewing angle LED display.

The factors that affect the viewing angle of an LED wall display include the LED tube core package method, the module mask of the LED display, the pixel pitch, and the resolution.

1. LED Tube Core Package Method

The LED tube core packaging method is divided into SMD and DIP. The viewing angle of SMD is wider than that of DIP. The color of DIP is separated. It consists of three lamps, which block the color dispersion from different angles, resulting in a low viewing angle. The viewing angle of indoor SMD is greater than outdoor SMD, which is due to the height of the mask. The viewing angle of SMD lamp beads also varies according to the technical differences of manufacturers.

2. Module Mask

The thickness and height of the module mask will affect the viewing angle. Generally, the height of the module mask of outdoor products is higher, so the viewing angle of outdoor SMD is not as high as indoor. Similarly, the viewing angle is also affected by the expandability of the module mask due to heat.
