Leveraging QD and CSP, LED backlight and such a future......

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 QD, backlight technology can go this way

Shortly after the end of the AWE show, Samsung QLED TV series, so that QD in the field of television shine. 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 if you want to reshape the backlight, the program driving force is greater than the cost

CSP line in the LED industry for several years, looking back on the past LED new technology from the beginning of the amount of backlight, but CSP seems to be a bit acclimatized. Although the domestic TV companies have launched a CSP backlight TV, but the whole market volume and how much improvement. Compared to the beginning of the LED backlight situation, CSP seems to be more in the field of lighting. One reason, as the code R & D director Wang Lei said, CSP to replace the existing LED package does not have a great advantage, its price is not high.

Wang Lei believes that the only way to promote the current amount of CSP through the backlight is through the program, if only simply rely on CSP to promote the entire 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 packaging into the backlight, the main points of difficulty: first, the technology is relatively immature, there is a reliability risk; second, high cost, no driving force. Of course, do not rule out the development of ultra low cost CSP program, it is possible to change this situation. Megabytes of electrons are moving 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, this need to pay close attention to speed, because the new technology has been displayed in the periphery began to break through.

Multi technology camp confrontation, LCD short-term status 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.

Currently there are two camps, one is led by Samsung QLED pie, followed by its route is Hisense, TCL; one is led by LG OLED faction, the domestic representative is Changhong, SKYWORTH.

Speaking of these two technologies, from OLED TV, then in the OLED screen technology, LG's biggest competitor is samsung. LG is focused on WRGB OLED technology, while Samsung is focused on RGB OLED technology. And in the capture of the OLED TV market that time, Samsung and LG also lingering for up to 3 years of OLED patent dispute, but eventually persevered, but only one LG. Later, LG launched a modified version of the WRGB OLED, is a compromise of technology, and the choice of QLED exit Samsung, it formed the two factions now.

With regard to several factions of the display technology, Wang Lei believes that the current new technology will become a branch, but in the short term will not be a mainstream. Because the domestic LCD panel production enterprises, we can see that the current LCD or mainstream. And according to the data, in 2016 the total amount of TV in 2.6%, but the average size has increased by 6.3%, indicating that the entire backlight market sales are still increasing.
