Our Range of LED Display

Cathode and Anode

The individual red, green, and blue sub-pixels in a dvLED module can be powered in different ways, and the choice affects both power use and heat. Early dvLED displays drove each sub-pixel separately, an approach that proved inefficient.

COMMON ANODE

In the early 2000s manufacturers adopted a common-anode design: full supply voltage was fed to all three colors, and each sub-pixel throttled down to its required intensity. This improved stability and simplified power handling but wasted energy—especially in the green and blue channels—when matching the lower forward voltage of red. The result was higher power draw and more heat.
Full power into each sub-pixel
• PRO – Full range pixel performance
• CON – Significant heat and power inefficiency for G and B

COMMON CATHODE

By the mid-2010s the industry shifted to common-cathode designs, tying the cathodes of the sub-pixels together instead of the anodes. This let each color receive only the voltage it needed, improving power efficiency, reducing heat, and maintaining excellent pixel performance.
On-demand power into each sub-pixel
• PRO – Eliminated inefficiency for G and B resulting in much less heat dissipation from the display
• CON – Slight reduction in high-end range

Pixel Technologies

SMD SURFACE-MOUNT-DIODE

SMD pixels make up >95% of all dvLED today. Sub-pixel LED chips are arranged within a package which is then mounted to the PCB. Pixel packages are highly durable, rarely experiencing an issue within the package itself. Most SMD issues are the result of physical damage between the pixel package and PCB. SMD is available with gold or copper bonding wire, or in a flip-chip configuration. SMD can be fragile at fine pitches, so SMD is an excellent solution for displays above 1.2mm. With a protective epoxy treatment, even sub 1mm SMD become durable!

IMD INTEGRATED-MATRIX-DEVICE

IMD pixels have the same physical construct as SMD, combining multiple pixels into a single package. An area where SMD is not ideal is fine pitch applications. As the pixel package gets smaller, so does its connection to the PCB. For fine-pitch, this smaller footprint makes fine-pitch SMD fragile to handling and physical contact. IMD is an excellent solution for pitches below 1.5mm if not using a protective epoxy treatment.

COB CHIP-ON-BOARD

COB pixels remove the enclosure (package/encapsulation) used on every other type of pixel. Individual sub-pixel chips are placed directly on the PCB then the module is coated with a protective epoxy. This coating results in significantly more durable pixels, virtually eliminating the need for pixel repair. COB pixels are by default all flip-chip and without bonding wire, improving power handling and viewing angles. Due to the size of the LED chips and the protective epoxy, pixels of COB modules typically cannot be repaired.

MIP MICRO-IN-PACKAGE - HIGH BRIGHTNESS

MIP is the newest pixel technology. Like SMD, MIP arranges sub-pixel LED chips within a package. Unlike SMD, MIP uses much smaller chips. Using ‘micro’ chip (smaller than 200μm) adds several benefits. Depending on the application need, MIP pixels can be configured to provide extreme brightness or extreme contrast. MIP pixels are an excellent choice for premium displays and displays requiring more contrast or brightness performance than traditional pixel technology can provide.
