Have you mastered the installation of RGB Color LED Display Modules?

RGB Color LED Display Modules because of the particularity of the goods itself, device debugging links can often reflects the quality of goods, also determines the RGB Color LED Display Modules when use effect, therefore, display device debugging is a very important technical work, in this screen manufacturer to see more of the five kinds of devices are summarized methods:

1. Mosaic device: suitable for smaller indoor screens. Because the device space is small, in order to do not take up space, the area of the same huge fine that is excavated on the wall of the wall of the screen body area, the shenzhen RGB Color LED Display Modules is embedded in the wall of the wall. The demand wall is solid wall. The method of pre-selection protection is high cost.

2. Hanging device: it is applicable to the display module of RGB Color LED Display Modules and RGB Color LED Display Modules of the airport. The demand screen is small. It is necessary to have the address of the appropriate device, such as a beam or a passing beam on the top, and a rear cover usually in case of a screen.

3. Column type device: a device for outdoor advertising RGB Color LED Display Modules, which has a wide field of view, such as square, parking lot, etc. The size of screen size can be divided into single columns and double columns.

More than 4, wall-mounted device: suitable for indoor RGB Color LED Display Modules device, smaller (below 10 square meters), the wall needs is a solid wall, hollow brick retaining wall are not appropriate or convenient at this device.

5, the roof type device: mainly applied to outdoor advertising RGB Color LED Display Modules, device address mainly the structure of the roof, follow the add to the thought of building height level wind has to follow to add.

Current market driven approach of RGB Color LED Display Modules has two kinds of static scan and dynamic scan, static scan is divided into static compaction pixels and static virtual, dynamic scanning is also divided into dynamic realities and dynamic virtual; The driving devices are usually 1/2 sweep, 1/4 sweep, 1/8 sweep, 1/16 sweep. In a certain area of manifestation, the number of rows that are lit together with the total number of rows of the entire region is called the scanning method.

From the output of the driver IC feet to force between the pixels' point-to-point 'manipulation is called static drive, from the driver IC output pin to force between the pixels' point of column' manipulation is called scanning drive, can clearly see from the driven plate: static drive demand did not control circuit, high capital to teach, but work well, good stability, brightness loss taught, etc.; The scan drives the demand line to control the circuit, but the money is low, the manifestation function is poor, the brightness loss teaches large.

1. The principle of scanning operation is that: using the visual temporary retention feature of human eyes, the RGB Color LED Display Modules will be lit separately in a very short period of time. The lights on the screen weren't all bright for a moment, but we looked like they were on. For example: light up a indoor full-color 32 x16 point 8 sweep unit board, in 0.001 seconds, light up the number of rows as long as line 2, the rest is not bright, that is, and animation, film principle is the same, practice is the role of a piece of a picture, scanning speed immediately formed the animation effect.

2. The commonly used scanning methods are the following: 1/16 scan, 1/8 sweep, 1/4; Indoor single and double color is usually 1/16 scan, indoor full-color is usually 1/8 scan, outdoor single double color is usually 1/4 scan, outdoor full color is usually static scan.

3. The driving method is two kinds: constant current drive and constant pressure drive; Constant current has a number of circuit boards and chips so that the current can be stable, increasing the service life and stability of RGB Color LED Display Modules.
