QLED sales continue to grow steadily, technical grade differences determine the popularity of QLED
The battle for color TV technology around color expression is on the rise. At the beginning of 2018, 55-inch OLED TVs broke the ultra-low price of 6,999 yuan. At the same time, the key components of QLED products also showed a downward trend in prices. In the context of the difficult expansion of OLED supply, QLED is likely to seize the opportunity of price and scale advantage in 2018.
QLED sales continued to grow steadily
In 2017, QLED sales in the domestic market stood at the millionth mark for the first time. The scale of 1.1 million units not only accounts for 2.5% of the structure in the color TV market, but also achieves an annual increase of 95%.
The industry expects that in the context of the continuous decline in the cost of QLED quantum film products, the growth rate of QLED products in 2018 is likely to reach a new high, and the annual market is estimated to be between 2 million and 2.5 million units. This value is expected to reach 3.2 million units in 2019. At the same time, the market sales ratio between QLED and OLED TV will also expand again from the narrowing of 2016-2017. The market gap has grown from a minimum of three times to a fivefold direction.
The reason for the increase in QLED TV sales is mainly due to the cost reduction. There are two reasons why QLED TVs cost more than ordinary TVs. The first is that QLED as a high-end product, the overall configuration cost is higher. The second is that the cost of QLED quantum film has been relatively high, much higher than the traditional phosphor conversion film.
However, the price of QLED quantum film has begun to decline in 2017. According to statistics, the price of overseas quantum dot film is 80-100 US dollars / square meter, and the price of domestic quantum dot film is about 60 US dollars / square meter. Sigmaintell expects that the cost of quantum film will drop by about 20% in 2018, and the proportion of domestic brands to domestic film purchases is also increasing. Around 2020, the cost of domestic diaphragms is eager to drop to $20 per square meter - the latter is equivalent to a material cost of $130 for a 60-inch LCD TV. Although this cost is still nearly twice as high as that of the conventional phosphor film, the actual product cost increase is not much.
On the other hand, as the price of QLED quantum films declines, more mid-range color TV products will be equipped with quantum dot technology. This will further benefit the growth of QLED TV in the scale market after three years, and will continue to widen the gap between sales of qled TV and OLED TV.
The difference in technology level determines the popularity of qled
Unlike the popularity of OLEDs, QLED is showing unprecedented explosive power. Because, from a technical point of view, the current QLED is still an improved variety of LCD TVs.
Accurately speaking, the QLED TV on the market is mainly transforming the way LCD TV backlights produce white light: traditional LCD TVs use blue LED light source + green and red phosphor film to achieve white light; QLED TV uses blue LED Light source + green and red QLED quantum dot material film to achieve a white light source. The advantage of using a QLED material instead of a phosphor is to "increasing the color width by 30%". Since the QLED converts the blue light wave to red and green, the red and green wavelength distributions are more concentrated.
It can be seen that today's QLED TV inherits all the industrial systems of LCD TVs. Its new technology is mainly how to prepare QLED materials, and replace the phosphors in traditional conversion films with QLEDs.
In comparison, OLED TV is a new display technology that is different from liquid crystal. The commonality between the two lies in the front-end process of TFT. On the back end, OLEDs do not require the structure of a backlight module, and new technologies are needed to achieve dot matrix film formation of new materials. Obviously, as a new technology OLED requires more industrial innovation. This also leads to OLEDs far less than QLED products in terms of capacity expansion and technology maturity.
However, as a new technology OLED not only has the advantages of color on liquid crystal products, but also has the advantages of contrast, ultra-thin, flexibility and reaction speed. The latter is unmatched by the current QLED TV. That is, QLED achieves faster product adoption speed with less progress and fewer technology changes.
After the QLED era has been opened, new technologies are coming out
Of course, the popularity of QLED TV as an upgraded iterative product for liquid crystal is not the end of the liquid crystal display technology market. In the second half of 2018, liquid crystal products are eager to enter the era of mini-led backlights in the second half of 2018.
Recently, it was reported that Huawei, OPPO and Xiaomi plan to launch liquid crystal display mobile phone products with mini LED backlight panels in the second half of 2018. The main reason is the insufficient supply of OLED panels.
Mini-led technology refers to the replacement of the current millimeter and sub-millimeter LED particles with 100 micron LED particles as the core component of the liquid crystal display backlight. Smaller LED crystal particles make it necessary for the backlight to integrate more granular crystals to achieve sufficient brightness. And with more LED grain crystals, you can achieve more HDR accurate brightness adjustment in the backlight.
High-Dynamic Range (HDR) provides more dynamic range and image detail than normal images and video. The industry believes that, in combination with qled technology, the mini LED backlight allows LCD TVs to flatten OLED TVs in terms of color and dynamic contrast HDR adjustment. The mini LED backlight product is the most popular frontier research direction in the improvement of liquid crystal display technology, and it is also one of the future demand growth points of the LED industry bet.
