Our COB (Chip on Board) LED display screen represents the latest in LED display technology. It utilizes COB flip-chip technology, where LED chips are precisely bonded directly onto the LED module board.
This method employs constant-current drive to protect the LED surface of components, simplifying production processes and minimizing scratches the LED surface.
These advancements significantly enhance product stability, reliability, and overall display quality. The COB LED display is the top choice for indoor command control room LED displays, conference LED displays, and educational training LED displays,etc.
High definition & Reliability
COB packaging technology reduces the LED pixel pitch,and improves display screen resolution, providing a clear visual and auditory experience even at close range. At the same time, COB technique directly mounts LED on PCB boards, minimizing collisions and scratches LED surface,improving LED reliability.
High brightness & Accuracy
Flip-chip (FC) COB refers to LED chips mounted upside down on a PCB with electrical contacts facing downwards. It eliminates the wiring process found in Lateral-chip(LC) COB and further reduces steps in SMD packaging, such as converting LED chips into lamp beads and reflow soldering.
This simplifies the production flow and enhances LED accuracy.Additionally, Flip-chip COB technology makes the PCB reflective layer directs light emitted from the LED chips toward the front of the display, resulting in high brightness.
Indoor flip-chip COB LED display module size
Front maintenance
The LED display modules are installed on the cabinet using magnets, eliminating the need for screws and wires. It’s a plug-and-play setup, saving installation space and providing easy access for maintenance.
16:9 golden ratio for HD display
The cabinet size is 600×337.5mm, designed with a 16:9 golden HD display ratio. Its thickness is only 30mm, making it easy to transport and install.
