一、 Display performance

1. High resolution

Common ones include Full HD (1920×1080), UHD 4K (3840×2160) and even 8K (7680×4320). High resolution can make the image clearer and more delicate, and can present more details and rich content. It is suitable for occasions with high requirements for image quality, such as large-scale performances, high-end conferences, etc.

2. High brightness

Generally, outdoor LED display panel board need to be above 2000cd/m² to ensure that the picture is still clearly visible under strong light, such as direct sunlight; indoor LED display panel board are usually between 500-1500cd/m². High brightness can make the image brighter and more vivid, and enhance the visual impact.

Outdoor: >4500,5000nit
Indoor: >1000,1200nit

3. High contrast

Refers to the brightness difference between the brightest and darkest areas of the display, such as 3000:1 or even higher. High contrast can make the picture black and white clear, with richer layers, and can better present the details of the dark and bright parts.

4. High refresh rate

The refresh rate of outdoor LED display panel board is generally required to be above 1000Hz, and high-end products can reach 3000Hz or higher; indoor LED display panel boards are usually above 600Hz. High refresh rate can make dynamic pictures smoother and more stable, and reduce flickering and tailing.

5. Wide color gamut

It can display richer, brighter and more accurate colors, making the picture more vivid and realistic, and close to the colors of the real world. Generally measured by color gamut standards such as NTSC and sRGB, high-configuration LED display panel board usually have a wider color gamut coverage.

6. Fast response time

Generally within a few milliseconds. The shorter the response time, the faster the pixel changes from one color to another, and the less likely it is to have ghosting, smearing and other phenomena when displaying dynamic images.

二、 Pixels and structure

1. High pixel density

The higher the pixel density, the more pixels per square meter, the more delicate the display image, and the more natural the color transition, such as P1.2, P1.5 and other small-pitch LED displays.

2. Good uniformity

Including brightness uniformity and color uniformity, ensuring that the brightness and color on the entire screen are consistent, without obvious bright spots or dark areas, and no color deviation, and can provide consistent visual effects.

3. Good viewing angle

Both horizontal and vertical viewing angles are relatively wide, such as the horizontal viewing angle can reach 160°-170°, and the vertical viewing angle can reach 140°-160°. When viewed at different angles, the brightness, color and clarity of the picture can maintain good effects.

三、Stability and durability

1. High-quality components

Use well-known brands, high-quality LED chips, driver ICs and other core components, these components have better stability, reliability and longer service life.

Power supply: Chuanglian, Juneng, Mingwei (mean)
Receiving card: nova star, Colorite
Video processor: nova star, Colorite
Module: PCB thickness 1.6mm, 1.2mm/1.0mm on the market, the thicker the PCB, the less likely the lamp beads are to break, and fire-retardant materials are used
Lamp beads: The National Star brand is used, which has good stability; copper wire and copper bracket are used, which are better than iron; Kinglight
IC: chip, chip one, generally 3840HZ for general brushing; high brush 7680HZ requires additional money, no water ripples

2. Excellent heat dissipation design

For high-power, high-brightness LED display panel board, a good heat dissipation system is essential to ensure that the temperature of the display screen will not be too high when working for a long time, thereby extending the service life and reducing the probability of failure.

3. Good protection performance

Outdoor LED display panel board must have a dustproof and waterproof rating of IP65 or above, and can effectively resist the erosion of natural environments such as dust, rain, wind and sand; although indoor LED display panel board have lower requirements for waterproofing, they must also have certain dustproof and anti-static properties.

4. Long service life

Under normal use conditions, it can run stably for more than 50,000 hours, or even 100,000 hours, reducing replacement and maintenance costs.

四、 Function and control

1. Intelligent control system

Support remote control, and can adjust and manage the brightness, color, playback content, etc. of the led display panel board anytime and anywhere through the Internet or mobile phone APP. It can also monitor the working status of the display screen in real time, such as temperature, humidity, voltage, etc., and can promptly alarm and diagnose when a fault occurs.

2. Multiple input and output interfaces

Equipped with rich interfaces, such as HDMI, DVI, VGA, USB, SDI, etc., it is convenient to connect various signal source devices such as computers, TVs, cameras, players, etc. to meet the needs of different users.

3. Special functions

Such as touch interaction function, which can be applied to scenarios such as intelligent conference systems and interactive display platforms; support for 3D display function, which can bring an immersive 3D visual experience to the audience.
