In recent year, Mini LED has undoubtedly emerged as a new sector where LED companies and panel vendors actively enter. The reason is that the traditional LED backlight has been developing for many years, reaching a bottleneck in technology; the profit is relatively low as well. Meanwhile, OLED displays, which feature thinness and flexibility, are invading into the backlight display market. As the result, manufacturers that do not worked on OLED displays have turned to the development of Mini LED, a new product that is highly competitive in terms of function and cost.
