Dynamic information

Mini-LED technology is the miniature version of the traditional LEDs that emit light. It's more of a refinement of current LCD LED technology than something entirely new. They're mini- LEDs that work together to provide the backlight on LCDs. They lie beneath the LCD matrix and provide finer control over light intensity, resulting in a higher contrast ratio.

 

Many more LEDs can be put into the same space now that the LED form factor has been miniaturized. Based on the size of the screen, this permits countless LEDs to be placed into a panel.

 

Different applications of Mini-LED

The Mini - Led Backlight

In terms of smartphone applications, mini-LED backlight technologies outperform standard OLED technology. In advanced gaming monitors, backlit mini-LED display technologies are crisper and more compact than OLED displays, and they also offer improved color rendering while keeping great contrast and dazzling brightness. Mini LEDs are less expensive to manufacture, have a longer lifespan, and are immune to the "burn-in" and picture retention difficulties that plague regular OLED panels.

The Mini - Led Display

The market structure is slowly shifting due to the development of mini/micro-LED. Domestic and international display 0.9 products producers have consecutively introduced Pitch and are aggressively deploying extra - small Pitch displays in the field of tiny pitch (P1.25) displays. Traditional panel makers are aggressively fighting for the future display market in the corporate world. Because the single LED device is too tiny, the standard SMD packaging is too difficult to produce. The precision of current equipment and supporting systems is insufficient for the production of lower pitch goods. Inventors have created a new sort of SMD product that is more precise than standard one-piece designs.

 

Automotive, section

Direct-view LED screens in vehicles are another use for which tiny LEDs were created. When viewed directly, OLED displays can be excessively bright, yet when viewed indirectly, they can be too dark, making them unsafe for use in-car displays. Because of their greater granularity and brightness control, mini-LED technology has overcome this problem. Backlighting for automobile displays such as HUDs, dashboards, in-vehicle entertainment systems, and rearview mirror displays has shifted to mini-LED. Mini LED was also used by certain LED manufacturers to demonstrate conceptual uses of exterior car lighting.

 

· Direct view LED displays

A chip on board (COB) design may be used to incorporate small LED displays, controlling the brightness and colors of each mini-LED technology in the display without the requirement for an externally integrated driver. This type of integration, as indicated in the section on automotive applications, allows this technology, which is preferable for usage in automotive and related direct-view small applications, to be smoothly incorporated as a single package. Mini COB provides several advantages, including the ability to successfully prevent issues caused by humidity, static electricity, and other environmental or human variables in standard SMD packaging narrow pitch LEDs. Heat is dissipated directly via the PCB board, which results in a greater heat dissi

pation effect.

 

Component of Mini-Led Technology

Thousands of small LED backlights are used in mini-LED technology to provide substantially improved local dimming characteristics. These backlight diodes must be smaller than 0.2mm wide to be classified as mini-LEDs. LCD screens require local dimming because backlight bleed causes poor blacks and contrast ratios as compared to OLED displays, which have individual pixels that switch on and off. This is a hybrid method that tries to mimic OLED's emissive properties while requiring less design complexity:

1. Mini-POB solution (Gypsophila solution)

To achieve a broad light-emitting angle from the lamp beads, use 1919 package size lamp beads that are SMT on the PCB. The lamp beads should have an OD of 5-12mm. It is a high-quality choice for the backlight solution of mid-to-high-end TVs, with a limited number of lamp beads in the backlight solution and the current solution's cost being significantly cheaper than the mini COB solution. Lightness and thinness, as well as high brightness, dynamic ratio, and color gamut, are all possible with this product. The firm can supply highly cost-effective solutions for TVs of all sizes and OD values, as well as local dimming IC, drive solutions, and PCB circuit architecture.

2. Mini-LED Display

Mini-LED displays are available in two series: COB Module and COB Cabinet, both of which include a module, cabinet, and full solution.

3. Mini-COB solution

Flip-chip in its entirety mini-COB solution technology reduces the need for SMD brackets and SMT reflow soldering, while also reducing the danger of inadequate soldering and increasing dependability. The full-flip COB provides surface protection and can resist larger external pressures, lowering the expense of damage and maintenance in the future. The whole flip chip is directly placed on the PCB, lowering the bonding wire eutectic failure factor and increasing dependability.

 

Technical advancement of Mini-LED Technology

Deeper blacks, better contrast ratios, and brighter screens are possible thanks to millions of tiny backlights, which is ideal for HDR content. It's all because of the smaller components. Because the size and density of the backlights are not limited, mini-LED technology can readily grow from tiny to large panel sizes.

 

Refond's technical advantages and achievements

Refond began working with large local and international customers to create Mini-LED-related goods. It was one of the first businesses in China to start researching and developing Mini LED technologies, and it has a significant technological and customer base. Refond's Mini-related technology can be used in a variety of electronic devices, including smartphones, televisions, tablets, and virtual reality headsets.

 

In close collaboration with well-known electrical businesses both at home and abroad, Refond has created a variety of mini-backlight and display product solutions. Refond optoelectronics built the first mini-LED technology automated manufacturing line in 2017. It is one of the first companies in China to accomplish mass manufacturing of Mini-LED goods.

Conclusion

Mini-LED technologies are the ultimate experience, combining the benefits of conventional LCDs with OLED screens. They provide the contrast of OLED panels while being considerably easier and less expensive to manufacture than OLED displays. Furthermore, because Mini-LED technology panels are so simple to make, they may be utilized to make small displays like those seen on laptops, tablets, and even smartphones.
