Products with more advanced LCDs appear. It is an LCD that has greatly improved brightness, HDR, and color reproducibility by adding QD film and mini-LED to BLU. The existing top-level LCD used a full array local dimming (FALD) BLU with a local dimming zone of about 300 to 500. When the local dimming zone is increased to more than 3,000 by using mini-LED, the contrast ratio is significantly improved, and the halo effect is reduced compared to FALD BLU LCD TVs. In order to achieve the same performance as OLED, the local dimming zone must have as many pixels as the number of pixels, but due to the limitation of LED size reduction, mini-LED TVs to be sold this year will have a local dimming zone of 1,000-3,000 products. To make the best LCD TV, a TFT substrate capable of AM driving mini-LED BLU is needed. The competitive pointer of LCD TVs using mini-LED BLU is a technology that can make the image quality similar to OLED while minimizing the local dimming zone and the number of LEDs. In order to realize the same image quality as OLED, the local dimming zone must be more than 100,000 divisions, and hundreds of thousands of LEDs and TFT substrates are required for driving, so the manufacturing cost of panels (including modules) becomes similar to that of OLED. If the backplane of the mini-LED BLU uses FR4 or BT and the local dimming zone is divided into 3,000, the mini-LED TV manufacturing cost can be reduced to about half of that of the OLED TV, maximizing the quality of the LCD TV while lowering the price. The TV with the best cost performance is created. The manufacturing cost of mini-LED BLU for 65-inch TVs with a local dimming zone of 10,000 divisions or less is analyzed at 250-1,100 dollars level, and the TV price is expected to range from 1,500 to 6,000 dollars depending on the size and local dimming division level. In 2021, the mini-LED TV market is expected to form 2.5 million units. In terms of market share with OLED TVs, mini-LED TVs are expected to dominate after 2024. TCL has led the development of Mini-LED TVs, but the market will be led by Samsung Electronics and LG Electronics..
