But nowadays, with the discovery of various higher quality materials, various new technologies are developed. In the display field, a new life has been bred, and their development prospects are broad. They have to be frightened by the LED display industry. Perhaps, the emergence of these new displays will bring a huge impact to the LED display.
Do you know all kinds of LED big inventory?
UV LED
UV LED is a kind of LED, namely ultraviolet light-emitting diode, with a wavelength range of 10-400 nm, which is a single-wavelength invisible light, generally below 400 nm. It has the characteristics of cold light source and no heat radiation. The surface temperature of UV LED is low, which can solve the long-term thermal damage problem in optical communication and liquid crystal production. Therefore, it is especially suitable for liquid crystal edge sealing and film printing. Applicable occasions. Moreover, the UV LED generates a small amount of heat, emits high-purity single-band ultraviolet light, has almost no infrared output, and the processed part is not deformed by heat, and is more suitable for processing and use by a worker.
The mainstream of UV LED development is UV ALED and UV CLED, among which UV ALED is more focused on the photocuring market. Recently, some media have estimated that the output value of UV LED in the light curing market will reach US$81 million in 2016, and will reach US$195 million in 2021. The annual compound growth rate will be 19%. The penetration rate of UV LED curing module will reach 50 in 2020. -60%. The latest "2016 UV LED and Infrared LED Application Market Report" shows that the market value of UV CLED sterilization and purification applications in 2016 will reach 28 million US dollars, and will reach 257 million US dollars in 2021, with a compound annual growth rate of 56%. Multi-LED manufacturers will launch new products by the end of this year, which will accelerate the progress of UV CLED technology.
IR LED
The IR LED is an infrared LED. The shape of a normal IR LED is similar to that of a general visible LED, but it emits infrared light. The tube pressure is generally reduced by about 1.4v, and the operating current is generally less than 20mA. In recent years, the output value of infrared LEDs has continued to grow in demand for applications such as security industry monitoring, virtual reality devices and facial and iris recognition. It is estimated that the size of the infrared LED market will be approximately US$300 million in 2016 and will grow to 792 million in 2021. The US dollar (equivalent to RMB 5.282 billion) has a compound annual growth rate of 21%.
At present, fingerprint sensing technology is relatively mature, but under the development of iris recognition applications, many companies have begun to deploy iris recognition applications. Samsung Galaxy Note 7 has strong iris recognition, which can confirm the identity of users when unlocking and paying for action. Although Note 7 is not the first mobile phone equipped with an iris unlock, it has been a hot topic. Earlier, the industry also reported the layout of OSRAM. It is reported that OSRAM plans to invest the funds that will be used in the LED chip factory to IR scanning and other iris scanning technologies, and plans to invest at least 100 million euros in Regensburg, Germany. LED wafer fab.
IR LEDs have a long history of development and their applications are everywhere in life. As mobile phones and wearable devices gradually introduce bio-sensing, even biometric functions, and IR LEDs can be combined with applications such as the Internet of Things, the future market has considerable growth potential.
Micro LED
Micro LED technology, namely LED miniaturization and matrixing technology. Refers to a high-density and small-sized LED array integrated on one chip. For example, each pixel of the LED display can be addressed and individually driven to light. It can be regarded as a miniature version of the outdoor LED display, and the pixel distance is from millimeters. The grade is reduced to the micron level.
The advantages of Micro LED are obvious. It inherits the characteristics of high efficiency, high brightness, high reliability and fast response time of inorganic LED, and has the characteristics of self-illumination without backlight. It is more energy-saving, simple in mechanism and small in size. Thin and other advantages. In addition, a major feature of the Micro LED is its high resolution. Because of the ultra-small performance, the resolution of the performance is particularly high. The industry believes that Micro LED has become an industry hotspot. As long as the yield and accuracy of Mass Transfer have been overcome, it is just around the corner in small-size applications. At present, LuxVue purchased by Apple has developed Micro LED for many years. In addition, Taiwanese companies such as AUO, Innolux, Jingdian, Yuchuang, and Industrial Technology Research Institute are developing; international companies such as Nichia, Sharp ( Sharp), Sony, BOE, and Huaxing Optoelectronics have not been absent. Even the OLED camp supporters Samsung Display and Lejin Display are also developing.
OLED
OLED is an organic light-emitting diode, also known as organic electro-laser display, which was discovered in the laboratory by Chinese-American professor Deng Qingyun. OLED display technology has self-luminous properties, using a very thin coating of organic materials and a glass substrate. When there is current, these organic materials will emit light, and the OLED display screen has a large viewing angle and can save energy.
OLED has a wide range of applications, and currently the most popular areas are OLED car lighting, mobile phone screens, head-mounted displays, and other potential areas. In addition, OLED + graphene, OLED + VR are optimistic about the industry.
With the continued high demand for OLED lighting panels, especially in the field of OLED automotive lighting, it is expected to lead the mainstream market of OLED lighting. It is estimated that the market share of OLED car lighting will reach 2 billion yuan in 2019, which will exceed the OLED indoor lighting market by then, and the OLED indoor lighting market is expected to be around 1.2 billion yuan in 2019. In the field of mobile phones, Xiaome's Note2 screen is based on OLED flexible screens. Apple is also determined to adopt OLED screens on flagship mobile phones next year. Other mobile phone manufacturers are also following OLED flexible screens. Head-mounted displays with video glasses and portable cinemas have become more and more widely used and developed. OLEDs have great advantages in the application of head-mounted displays: clear and bright full-color display, ultra-low power consumption, etc., is a major driving force for the development of head-mounted displays.
A variety of LEDs to develop traditional LED will be a competitive crisis?
In the field of display, many powerful competitors have emerged, and the advantages of these LED branches have gradually emerged compared to traditional LED displays. These advantages not only make up for traditional LEDs, but in some applications, their advantages far exceed those of traditional LEDs. For example, IR LEDs have a lot to do in the field of monitoring and security; Micro LEDs are ultra-small and can be used for precise display of mobile phone screens; UV LEDs Can be used for medical and biological monitoring, which will impact traditional LED applications.
Moreover, in addition to the competition of various LEDs for traditional LEDs, there is an inevitable mutual competition between these subdivided LEDs. At present, OLED is relatively mature, and it has been very effective in the application of mobile phone screens. Now it has been launched and has received good feedback, and OLED TVs have also appeared, and its flexible display has high precision and excellent display effect. In the future, there will be even greater breakthroughs in OLED panels.
Industry insiders have predicted that the market for OLED panels will replace traditional LEDs. However, OLED also has certain disadvantages. Although the cost of materials is much lower than that of traditional LEDs, its manufacturing price is very high. This is also the Achilles heel that OLED is currently difficult to expand. At present, traditional LED materials have turned to price surges after a long-term price war, and the soaring LED materials have also won greater development opportunities for OLEDs. At this time, if OLED manufacturing technology can keep up with market demand, it will break through. After this manufacturing problem, the impact of OLED on LED will be even greater. This is why the industry is rumored that OLED is about to replace traditional LEDs.
At present, in fact, UV LED, IR LED, Micro LED, OLED have not reached the mature stage, and the application of traditional LED has long been popular, which is the biggest advantage of traditional LED. LED downstream applications are divided into LED lighting and LED display. The LED lighting industry has unparalleled advantages in commercial lighting and living lighting, landscape lighting, and plant lighting. LED display products are often used in large-screen applications. Since the OLED panel is self-illuminating, because it does not require the characteristics of the backlight, the thickness of the panel can be reduced, and the trend of thinness and lightness can be catered for, but also because the backlight source is not used, the backlight module factory and the LED factory are named as new technologies. Victims under change, this kind of impact will certainly attract huge concerns in the LED industry. It should not be overlooked that in addition to the strong competition of OLED, IR LED and UV LED also ushered in the blue ocean market. How traditional LEDs will go in the market competition will determine the future status change in the LED field.
Although the development of the situation has to be worrying, but many industry professionals believe that in the short term, the new Blue Ocean LED does not have the ability to catch up with traditional LED. Li Bingjie, chairman of Jingdian, pointed out that OLED is a surface light source. There is still a requirement that the surface light source cannot be achieved in household LED lighting. The rise of OLED has a good influence on household lighting. On the backlight, he believes that there is still a price difference between LCD and OLED. It has little effect on large-size applications, mainly on small-sized panels. Su Feng, chairman of Ronda, said that the number of LEDs used in backlights is related to the area. Due to the wide range of LED applications and mobile phones, NBs, monitors, tablets and TVs, TV mainstream sizes are moving above 40 inches. The impact of these LED branch materials and technologies on the overall traditional LED output value should be limited.
Therefore, whether in lighting or in the display, the advantages of traditional LEDs are still stable. Under the impact of various LEDs, traditional LEDs will not be killed on the beach in the short term, but the crisis of this competition is always There is a diversified development of China's LED industry. It will become a trend. In the face of impact, LED companies will deploy a new blue ocean market, take a differentiated route, seek new development opportunities, and so on. How to develop the LED industry depends on how the major companies shine their swords.
