Through QD and CSP, and the future of LED backlight......

In recent years, with the launch of OLED heat rising, the market is more and more big mouthing LCD shouts, as backlight LCD dependent nature is also subject to the same "courtesy", in order to understand the backlight market situation, the recent dramexchange consulting its brand LEDinside LED research team visited one of the representative enterprises in Shenzhen backlight zhaoma Electronic Co. Ltd. analysis of the current development of dialogue and research director Wang Lei LED Backlight Market and future direction.

Leveraging the QD backlight technology can go

Just shortly after the end of the AWE show, Samsung display QLED TV series, QD to shine in the field of television. The backlight will impact the LCD TV QLED, MPEG electronics R & D director Wang Lei said, is still in infancy, the development of QLED, the Samsung QLED TV is not the true sense of the QLED TV, the principle is still passive light blue light excitation LED quantum dots film based on quantum dots from real active luminescence QLED TV is still a long way, it is also based on this, the code does not worry about the impact to the mega backlight market, because the film is based on the quantum LED backlight TV products, in the short term to sign code does not constitute a threat.

At the same time, Wang Lei also revealed that the MPEG electronics has developed the quantum dot related products, and has been in the state of delivery; quantum dot products still further developed in situ MPEG electronics package, and strive to QD materials directly encapsulated in a single LED, increase the versatility of the product, in order to achieve high color gamut; but because of fear of material QD if the characteristics of hot oxygen, can not be applied to the existing packaging conditions (LED chip high surface temperature and silica gel blocking ability is poor), so in situ package was the need to address is oxygen and heat dissipation, is expected to Q2 will launch the sample.

CSP want to reshape the backlight driving force is greater than the cost of project

The CSP line in the LED industry for several years, looking back at the past LED more than the amount of new technology in backlight, but CSP seems to have The climate does not suit one. Although domestic TV companies had launched CSP TV, but the whole market volume and get much improvement. Compared to LED at the start of the backlight situation, CSP seems to be more heat in the lighting field. The reason as MPEG Electronics Research Director Wang Lei said, CSP to replace the existing LED package and no great advantage, its price is not high.

Wang Lei believes that the current through the CSP method only push the backlight is through the program, if only rely on CSP to promote the whole industry is difficult. Because now CSP with the past side entering type instead of case type backlight is not the same, the last direct type substituted side entering type is can reduce the system cost greatly, and the direct type light profit is still at a high level, it is also because of this driving force to push up.

But now the CSP to replace the existing package into the backlight, the difficulties are mainly as follows: first, the technology is relatively mature, reliable risk; second, high cost, no driving force. Of course, do not rule out the now development of ultra low cost CSP scheme, may change this situation. Megabytes of code electronic also go in this direction.

Although the CSP in the backlight field has been unsuccessful, but in the lighting market is like a raging fire. The lighting fields have launched CSP products, so the cost of CSP is also accelerating decline, this is a good thing for the backlight, because CSP itself is a cost saving scheme, if you replace the original product or a certain profit driven, compared to the current backlight products of low margin business, there is no reason not to choose. Of course, the need to speed, because the new technology has been displayed in the periphery began to break.

Multi technology camp confrontation, LCD short-term position difficult to move

About the new technology of peripheral breakthrough, current TV display technology, LCD, OLED and QLED are three of the world, where LCD is the traditional mainstream LCD TV, the new technology of QLED and OLED while watching the competition is still in existence but represent the general trend, each of the problem.

There are two camps, one is led by Samsung, QLED, Hisense, followed the route is TCL; one is headed by LG OLED, the domestic representative is Changhong, SKYWORTH.

The two technique, from OLED TV, was in the OLED screen technology, the biggest competitor is Samsung LG. LG is focused on WRGB OLED technology, Samsung focus is RGB OLED technology. But during that time the capture of OLED TV market, Samsung and LG still lingering for 3 years OLED patent dispute, but eventually persist, but only a LG. Later LG introduced a modified version of the WRGB OLED, is a compromise, while Samsung exit QLED, also formed the two major factions now.

A few factions display technology, Wang Lei believes that these new technologies will become a branch, but in the short term will not be a mainstream. Because from the production of domestic LCD panel business, we can see that the current LCD is still the mainstream. But according to statistics, in 2016 the total TV dropped by 2.6%, but the average size is up to 6.3%, which indicates that the entire backlight market sales is increasing. (the /LEDinside Skavy)
