Detailed explanation of small-pitch LED display mainstream front maintenance plan


In the second half of 2018, well-known small-pitch LED manufacturers in the industry have successively launched small-pitch cabinets that can realize real front maintenance: modules, power supplies, and control cards can be loaded and unloaded before, and there is no need to leave a maintenance channel behind the cabinet. Why do these companies hesitate to invest in research and development to realize the front maintenance cabinet structure of small-pitch LEDs?

Because in the indoor display application environment such as video surveillance, command and dispatch, it is determined that front maintenance must become the standard configuration of small-pitch LEDs.

First of all, in indoor display applications, because the data, graphics, and video signals played on the screen are small, it is related to the economic interests of the enterprise, and the large is related to the national economy and the people’s livelihood. Display, even if there is a problem, it can be repaired quickly.

In addition, the traditional indoor small-pitch LED display screens are all installed with steel structure, and the rear maintenance channel is adopted. Even if some manufacturers adopt the front maintenance, it can only be used for the front maintenance of the module. This maintenance method greatly hinders the application of small spacing in meeting rooms and central control rooms with limited space, and also brings difficulties to replacing LCDs. It cannot highlight the advantages of small spacing LEDs and greatly reduces customers' abandonment of DLP/LCD, etc. The willingness of traditional display equipment to replace small-pitch LEDs.

Therefore, the real meaning of the emergence of small-pitch LED cabinets before maintenance, so that the advantages of small-pitch LEDs can be fully reflected, whether it is for small-pitch LED manufacturers, engineers, integrators, and end users. Gospel.

Small pitch LED

Compared with the rear maintenance cabinet, the front maintenance has many advantages:

1 The thickness of the screen is small: no maintenance channel is required, which can greatly expand the use space, reduce the decoration cost, and meet the requirements of small space or high screen thickness.

2 Convenient maintenance, saving manpower and travel costs: no need for professional engineers, the customer only needs one person to install, wire, disassemble, repair, and replace spare parts in the front.

3 Increase the viewing distance: Because the small-pitch display screen is for indoor viewing, it has certain requirements for the best viewing distance. The thickness of the rear maintenance screen is at least 800mm, which shortens the distance between the display screen and the auditorium and reduces the viewing effect .

4 Reduce the cost of decoration: the front maintenance screen is installed on the wall and the thickness is controllable, which can be better compatible with the surroundings and reduce the overall coordination cost of decoration.

A list of pre-maintenance solutions for major companies

Fine pitch HDV

The small-pitch HDV can be maintained in the real sense, and has the advantages of front and rear installation, wireless connection, multiple installation methods, ultra-thin and ultra-light.

HDV series cabinet size is standard 16:9 36 inches, which can easily realize 4k, 1080P, 720P and other HD and SD large-screen splicing. HDV is an innovative product with consulting services provided by the performance list.

Shenzhen Litestar LED CO., LTD. 55-inch independent display unit "D-MAX" cabinet has a thickness of 55mm. It adopts the real front maintenance design of the module, power supply, control board front installation and front disassembly to achieve wall-mounted installation, and the thickness after wall-mounted installation is only required. 88mm.

16:9. Full front maintenance, wall-mounted installation... The small spacing of LEDs installed on the wall-mounted front maintenance of Chip Opto-Electronics reflects the innovation achievements of the industry over the past year. This front-maintenance wall-mounted LED small-pitch product is also conceptually designed by a professional consulting team on the performance list. It does not change the original frame, installation method, video source, power distribution system and signal system of the LCD splicing. Make a perfect replacement.

In addition to the above solutions, some companies also adopt conventional traditional LED display front maintenance solutions. The main disadvantage of the traditional front maintenance is that the power supply, card, power cord, etc. are installed and fixed from the rear. The small spacing is a high-density screen. Both the control card and the power supply are more than ordinary in the same area. For the display screen, this method only solves the pre-maintenance of the module, and cannot realize the pre-maintenance of the entire installation.

Finally, after receiving the pressure of downstream applications, the concept of front maintenance is gradually spreading around the LED display: some current LED display related supporting locks have appeared front maintenance products, and at the same time The maintenance-matched wireless connection solution is also gradually mature in the connector field. With the downstream demand and the maturity of supporting materials, it is believed that more manufacturers will launch pre-maintained small-pitch LED products in the future.
