In the display technology, Mini LED stands out as a groundbreaking solution. However, no matter how impressive a new technology may be, its true value lies in the tangible benefits it delivers to customers. Practicality and quality should always be at the forefront. In this blog, we will explore the advantages of Mini LED Inverted.
High Reliability
Reliability is the cornerstone of user satisfaction. With an on-machine defect rate of less than 5 PPM (parts per million), Inverted Mini LED series boasts exceptional product stability. In simple terms, 5 PPM means that out of every one million LEDs, fewer than five are defective. This translates to significant cost savings for screen and end-users, with a 95% module yield rate.
The inverted structure of Mini LED enhances product durability and stability. Unlike traditional LEDs, they do not require wire bonding, resulting in larger chip spacing and eliminating issues like “whisker growth” caused by metal migration. As a result, these displays easily surpass a lifespan of three years.
High Brightness
Mini LEDs achieve HDR (High Dynamic Range) levels of brightness, making them versatile across various scenarios. They are energy-efficient, offering a cool screen experience that reduces operational costs.
HDR technology demands peak brightness levels of at least 1000 nits. Mini LED, utilizing full inverted R/G/B chips, achieves brightness levels ranging from 1500 to 4500 nits, surpassing the requirements for HDR. Additionally, the brightness is adjustable, ensuring exceptional display quality across diverse applications.
The high brightness of Mini LED translates into energy savings. Inverted Mini LED products deliver the same display performance as conventional products with significantly lower current consumption. In practical terms, standard products consume almost twice the power of Inverted Mini LED displays for the same display performance.
For instance, consider a P1.25 2K screen running for over 8 hours a day. By using Inverted Mini LED instead of traditional LEDs, you can save enough on electricity bills in two years to cover the cost of a large display.
Furthermore, Inverted Mini LED adopts common cathode technology, enabling precise control of each chip’s power supply. This minimizes energy loss and heat generation. Even if there is heat generated, it is efficiently dissipated to the substrate, ensuring a cool screen surface and changing the perception of large screens as “hot to touch.”
High Contrast Ratio
A high contrast ratio of 100,000:1 ensures clear and vivid images with rich layers and vibrant colors. Contrast ratio measures the brightness ratio between the brightest (white) and darkest (black) points on the screen, determining the screen’s ability to differentiate between light and dark levels.
A high contrast ratio means more layers of differentiation between light and dark, resulting in smoother transitions and sharper, more vibrant images. Lower contrast ratios tend to produce washed-out images, while higher contrast ratios enhance image clarity, vividness, and color accuracy.
Mini LED boasts a contrast ratio of 100,000:1, delivering breathtaking picture quality and an immersive visual experience.
Ultra-Thin Packaging
Inverted Mini LED packaging is thinner than traditional packaging, with a device thickness of only 0.48mm compared to traditional packaging at 0.85mm (using 1010 as an example). Thinner packaging allows for greater LED chip thrust, enhancing resistance to impact and reducing LED chip damage. This results in extended screen lifespan and reduced maintenance costs, improving overall product stability and reliability.
Moreover, Inverted Mini LED’s ultra-thin packaging design facilitates panel-level packaging (GOB), reducing secondary packaging gel stress and minimizing module warping. It ensures a tight fit with the panel, maintaining product flatness and stability, meeting panelization requirements, and enhancing screen uniformity and aesthetics.
