LED DISPLAYLED DISPLAY SCREEN is the outstanding products of Only Optoelectronics Technology, which has been dedicated in the research, development and manufacture of LED display screen for more than 5 years.
LED display screen can be used both indoor and outdoor, say indoor LED display screen and outdoor LED display screen. LED display screen has been widely used for advertising and amusement. We can see LED advertising screens: , LED signs, LED billboards, LED scoreboards, and LED messages everywhere around us, such as Educational institutions, plazas, Government securities transactions, shopping centers, airport, stations, piers, banks, postal services, stages, outdoor advertising medias and so on.
LED display screen is the new concept in the advertising field; it can help promote sales with its colorful and attractive pictures, videos. It is widely welcomed and will surely be the trend in this line.
How to recognize the LED display
The difference between scanning LED Display : LED screen scanning method:
Scanning mode: the display in a certain area, while the number of lines and light lines the proportion of the entire region.
Indoor single color is generally 1 / 16 scanning, indoor full color is usually 1 / 8 scan, Outdoor single color is usually 1 / 4 scan
Outdoor led display full color scanning is generally static.
LED display on the market-driven approach has both static scan and dynamic scan, static scan pixel is divided into static and static virtual reality, dynamic scanning is also divided into dynamic real image and dynamic virtual; drive the device for general use made HC595, Taiwan MBI5026 Toshiba TB62726, generally 1 / 2 sweep, 1 / 4 scan, 1 / 8 scan, 1 / 16 sweep. Give out Description: A popular full-color module pixels 16 * 8 (2R1G1B), if MBI5026 driver module is used in total: 16 * 8 * (2 +1 +1) = 512, MBI5026 for the 16-bit chip, 512/16 = 32
(1) If 32 MBI5026 chips, is a static virtual
(2) If 16 MBI5026 chips, is a dynamic 1 / 2, the virtual scanning
(3) If 8 MBI5026 chips, is a dynamic 1 / 4 scan virtual
If two red thread on the board
(4) 24 MBI5026 chips, is a static implementation of pixels
(5) with 12 MBI5026 chips, is a dynamic 1 / 2 pixel solid brush
(6) with 6 MBI5026 chips, is a dynamic 1 / 4 Real scan pixel
In the LED unit board, scan mode, 1 / 16, 1 / 8, 1 / 4, 1 / 2, static. If different? One of the simplest ways is to count the number of units and the led display board the number of 74HC595.
Method: LED divided by the number divided by the number of 74HC595 8 = fraction of the scan
Are the real and virtual pixels corresponding to: In simple terms?
Constitute a real pixel screen display means the three RGB LED in each LED in the end only one pixel image used to obtain sufficient brightness.
Software algorithm is the use of the virtual pixels of each color LED control to participate in the final image which multiple adjacent pixels, which makes the lamp to achieve more with less resolution, enabling the display resolution four-fold increase.
