The brightness of the Incell screen for iPhone 12 series launched by BIZBEE can reach 700cd / m ², and the thickness is about 0.3mm thicker than the original. Almost all parameters are very close to the original. How is this achieved? Read the following and you'll find the answer.
1. Introduction to the principle of Mini-LED backlight technology
Mini-LED backlight adopts direct-lit LED backlight mode. It reduces the traditional LED grain size to between 100 microns and 200 microns, greatly increasing the number of backlight. For example, the original side backlight has only a few dozen lamp beads, but now it can reach thousands, tens of thousands, or even more.
Besides, the flip-chip method of Mini-LED does not require a lens for secondary optical design. Due to the relatively small structure of the chip itself, it is conducive to achieving higher contrast and can also achieve the effect of ultra-thinness. In addition, Mini-LED combined with Local Dimming technology can achieve tens of thousands of zone control, more precise light control ability, and can achieve peak brightness up to 1000 or even 1400nit, and the contrast can reach 1,000,000:1, making the display effect closer to natural.
2. The advantages of Mini-LED backlight
The main technical advantages of Mini LED backlight products: First, it is light and thin. Because the size of Mini LED chip is smaller, the optical mixing distance can be greatly reduced, and even the distance can be reduced to 0, making the overall thickness of the display closer to the OLED panel, achieving the light and thin effect and expanding the scope of application.
