LED дисплей на компанията SM, творчески готини идва

Наскоро, външният LED дисплей на SM Company е много горещ. Когато се приближите, изглежда, че морският бриз духа върху рибния резервоар през лятото.
Този дисплей е създаден от Samsung, с площ от почти четири баскетболни игрища, and a resolution of up to 7840×1952. Тази резолюция е два пъти по-голяма от тази на Ultra HD. It is currently the world’s largest outdoor high-definition display and is full of coolness. LED дисплеят постепенно върви в челните редици на творчеството, и различните технологии стават все по-зрели. LED дисплеят може да бъде разделен на няколко цвята, пълноцветен дисплей, монохромен дисплей, и двуцветен дисплей. И също така разделени на вътрешни и външни и полуоткрити LED дисплеи, SM company created this wave dynamic display screen as an outdoor display. The function of the LED display is mainly used to publish information, traffic guidance, advertising, screens installed on stairways, stadium screens, и т.н.. Следователно, the display screen with good appearance and strong dynamicity is also more infectious. As a доставчик на сценично осветление & производител, we are eager to hold a light exhibition one day
Let me talk about the professional terminology of LED display and how to check its quality.
Първо, the professional terminology of LED display

1. LED display brightness
The brightness of the LED display is expressed by the luminous intensity, and the unit is candela.

2. Resolution
The resolution of the LED display refers to the total number of pixels, which also determines the information capacity of the display. That is, the high-resolution display allows people to see the product information more intuitively.

3. LED pixel module

The pixel modules used for indoor and outdoor and semi-outdoor displays are different. Pixel modules are LEDs arranged in a matrix or pen segment and finally, form a standard-sized module.

4. The relationship between dot pitch, information capacity, and pixel density In LED displays, the smaller the dot pitch, the better the resolution and the higher the resolution. Pixel density is directly proportional to information capacity and inversely proportional to dot pitch. The larger the dot pitch, the lower the pixel density, the less the information capacity, and the farther the viewing distance is. vice versa.

5. Grayscale
Grayscale refers to the degree of light and dark changes in pixels.

6. LED display
Arrange the LED into a matrix or pen segment, това е, change its actual required size into a standard size, and combine it with a dedicated display circuit and software to form an LED display screen.

7. How to check its quality

1. Flatness
Whether it looks smooth and clear, and observe whether the viewing angle is harmonious.
2. Brightness and viewing angle
The indoor brightness and outdoor brightness should also be in different ranges, which should be reasonably controlled, and it is best to adapt to the LED packaging brightness.
The viewing angle is preferably above 150°. Generally, the larger the viewing angle, the better.
3. Are there any color blocks, dead spots, and mosaics
The control system is good, and it is not easy for color patches to appear when the scanning frequency and gray level are high.
Imperfect anti-static measures and poor IC or connector quality are prone to dead spots and mosaics, so you should avoid the above situations when choosing.
4. White balance
White balance generally requires the appearance of pure white without deviation, such as color difference and color cast.
