2. The application prospects of Mini LED in the small size of mobile phones
①Mini LED has unlimited potential to achieve "high screen-to-body ratio"
Full screen is an important trend in mobile phone display technology. In 2017, all major first-tier mobile phone brands almost all crossed the threshold of 80 percent screen-to-body ratio.
Because the traditional edge-lit backlight solution needs to leave room for the side backlight LED lamp beads, the traditional "LCD plus edge-lit LED" backlight method cannot have a high screen ratio under the premise of thinning.
The emergence of Mini LED has completely solved this problem-by minimizing the size of the LED chip, under the premise of achieving a thinner, the direct-lit LED backlight is used without occupying the side space of the mobile phone.
Therefore, a "high screen-to-body ratio" display effect can be achieved. In addition, because it can achieve a high dynamic range screen effect through the Local Dimming design, it can present a more detailed screen picture.
Not only is the thickness of the screen almost the same as the OLED, the performance is also quite good. It can be seen that in the battlefield of small-size display, the mini LED with great potential also has the opportunity to compete with the hot OLED screen.
②Mini LED backlight high-end screen helps get rid of monopoly
At present, the mainstream technology for high-end smartphones to achieve high screen ratio is OLED. Subject to patent protection and technical barriers, the OLED market is almost monopolized by a few manufacturers such as Samsung, and terminal manufacturers have poor bargaining power.
In a sense, this hinders the penetration of high-screen-to-body mobile phones into low-end models. In addition, the reliability of OLED screens has yet to be subject to wider market inspections (such as the Huawei green screen door incident at the end of 2018).
Terminal manufacturers urgently need to find another affordable and more reliable high-end display solution beyond the OLED path, so Mini LED backlight solutions have begun to enter the field of vision of major mobile phone manufacturers.
3. The car display market will become another blue ocean for mini LED backlights after TVs and mobile phones
Regardless of whether the OLED display or the traditional TFT LCD display is used in the vehicle display, there are still many shortcomings in terms of manufacturing cost and driving safety.
The Mini LED is an improved version of the traditional LED backlight plus TFT LCD display. It adopts direct lighting and fine HDR partition display, which greatly improves the contrast.
In addition to achieving low afterglow standby, energy consumption is also greatly reduced, and it has better high-temperature reliability than OLED, and has a life span as long as TFT LCD.
Based on the above logic, we believe that with the further maturity of technology, the car display market will become another blue ocean for mini LED backlights.
