P1.25 Indoor COB LED Display, as a high-density, high-definition display device currently on the market, is widely used in conference rooms, control rooms, exhibition halls, and other venues.

 

I. Technical Principles

 

Basics of LED Displays
An LED (Light Emitting Diode) display is a display device composed of multiple LED pixels, which realizes image and video display by controlling the brightness and color of each pixel. The pixel density (Pitch) of an LED display refers to the distance between adjacent pixels, measured in millimeters (mm). P1.25 indicates a pixel spacing of 1.25mm.

 

COB Technology
COB (Chip on Board) technology is a method of directly packaging LED chips onto a PCB board. Compared with traditional SMD (Surface Mounted Device) technology, COB technology offers higher integration and better thermal performance. Each pixel point of a COB LED display consists of multiple LED chips packaged in a small area, forming a high-density pixel.

 

Working Principle of P1.25 Indoor COB LED Display
The P1.25 indoor COB LED display adopts COB technology, directly packaging LED chips onto the PCB board to form high-density pixels. Each pixel is composed of red, green, and blue LED chips, and full-color display is achieved by controlling the brightness of each chip. The driving circuit of the display receives video signals to control the brightness and color of each pixel, thereby displaying clear images and videos.

 

II. Structural Design

 

PCB Board Design
The PCB board of the P1.25 indoor COB LED display adopts a multilayer design to improve circuit stability and thermal performance. The PCB board integrates components such as LED chips, driver ICs, and power management circuits. The application of COB technology makes the connection between LED chips and the PCB board tighter, reducing soldering points and enhancing the reliability of the display.

 

Packaging Design
COB packaging technology encapsulates multiple LED chips in a small area, forming a high-density pixel. The packaging material typically uses high thermally conductive epoxy resin to improve thermal performance. During the packaging process, gold wire bonding technology is used to ensure the reliability of the electrical connection between the LED chips and the PCB board.

 

Thermal Design
Due to the high pixel density of the COB LED display, thermal management becomes a key consideration in the design. The P1.25 indoor COB LED display adopts various thermal designs, including high thermally conductive PCB boards, heat sinks, and fans. These designs effectively reduce the operating temperature of the display, enhancing its stability and lifespan.

 

Driving Circuit Design
The driving circuit of the P1.25 indoor COB LED display adopts advanced constant current driving technology to ensure consistent brightness of each LED chip. The driver IC receives video signals to control the brightness and color of each pixel, achieving high-definition image display. The driving circuit also features overcurrent and overvoltage protection functions, enhancing the safety of the display.

 

III. Performance Characteristics

 

High Definition
With a pixel spacing of 1.25mm, the P1.25 indoor COB LED display has a pixel density of up to 640,000 pixels per square meter. The high-density pixels enable the display to present more detailed and clear images and videos, suitable for close viewing.

 

High Brightness
The application of COB technology makes the P1.25 indoor COB LED display have high brightness, typically ranging from 800 to 1200 cd/m². The high brightness allows the display to be clearly visible in bright environments, making it suitable for various indoor venues.

 

Wide Color Gamut
The P1.25 indoor COB LED display uses red, green, and blue LED chips, offering a wide color gamut and the ability to present more vivid and realistic colors. The color temperature of the display is adjustable, suitable for different application scenarios.

 

High Refresh Rate
The refresh rate of the P1.25 indoor COB LED display is typically as high as 3840Hz, effectively reducing image flicker and motion blur, making dynamic image display smoother. The high refresh rate also reduces eye fatigue, making it suitable for prolonged viewing.

 

Low Power Consumption
The application of COB technology makes the P1.25 indoor COB LED display have lower power consumption. Compared with traditional SMD LED displays, COB LED displays can reduce power consumption by 20%-30% at the same brightness. Low power consumption not only reduces operating costs but also minimizes environmental impact.

 

High Reliability
COB technology reduces the soldering points between LED chips and the PCB board, enhancing the reliability of the display. The P1.25 indoor COB LED display adopts high thermally conductive packaging materials and thermal designs, effectively lowering the operating temperature and extending the lifespan of the display.

 

Seamless Splicing
The P1.25 indoor COB LED display adopts a modular design, supporting seamless splicing. Multiple display modules can be spliced into a display wall of any size, with minimal splicing gaps that are almost invisible. The seamless splicing design makes the display more flexible for use in large venues.
