How to Achieve Super 4K Ultra High Resolution for Indoor Led Display
MiniLED backlight indoor screens market development potential should not be underestimated
In the process of industrialization of Micro LED, it faces the constraint of technical bottleneck such as huge amount of transfer. MiniLED indoor and outdoor can be divided into two application directions: RGB display and backlight.
How to Achieve Super 4K Ultra High Resolution for Indoor Led Display
MiniLED RGB indoor led display technology as a natural extension of the small pitch display, both downstream applications and process technology can be seamlessly connected, is expected to inject new sources of living water for the LED display church screens. In the direct display market, Mini RGB chips will gradually occupy the mainstream in display applications below P1.1.
And in backlight technology, the MiniLED backlight indoor led display has obvious advantages, not only can achieve ultra-high contrast, wide color gamut, making the color vibrancy comparable to OLED but also can reduce the optical mixing distance, reduce the screen thickness to achieve ultra-thin.
In addition, the MiniLED backlight display has the advantage of uniform heat dissipation compared to traditional discrete LED device solutions, which can achieve high brightness and make HDR possible.
MiniLED backlight is an important driver to accelerate the industrialization of MiniLED. the potential development of the MiniLED backlight market should not be underestimated
With the improvement of yield, the cost of MiniLED backlight display will drop by 15-20% per year, which will replace the existing traditional LED backlight by a large percentage and become the mainstream choice for large-size LCD backlight display solutions.
In addition, IT products will drive the high demand for MiniLED backlight usage, and MiniLED indoor led display is expected to be gradually introduced into the automotive display field in the past three years.
In terms of chip technology, the MiniLED flip-chip RGB chip has the advantages of lower chip thermal resistance, better visual consistency, no need for gold wire and better reliability in display applications.
TBC LED MiniLED backlight chip adopts a highly reliable and high brightness DBR+ITO flip-chip structure, which effectively solves the problem of having Ag silver migration and improves reflectivity through optimized DBR film layer design and deposition process.
In terms of reliability, TBC LED MiniLED backlight chip makes the soldering process more stable through the production of an efficient passivation layer and optimized film system combination to protect the side passivation layer. At the same time, the PV and Mesa etching process is optimized to smoothly cover the metal connection layer and improve reliability; in addition, the electrode structure and metal deposition process are optimized to block the diffusion of solder paste material.
TBC LED indoor led display MiniLED backlight chip solution has better light mixing effect, is suitable for full screen, can be driven by zoning, has higher contrast, higher color saturation, and more power saving. For consumer electronics, it can reduce the optical film and make the product thinner and lighter.
On the basis of solving the common technology of MiniLED backlight chip products, TBC LED is the first company in the industry to introduce mass production of solder-free packaging chip solutions, and the first high-voltage Mini backlight chip in the industry.
