Shopping malls such as the battlefield, the competition in the market is not inferior to the battle on the battlefield, just like the LED market is now emerging with new display technology, in addition to LED display, there are OLED, Micro LED, QLED in the market competition.
OLED flexible extreme display
Compared with the "New Star" Micro LED and QLED technology, OLED is a relatively mature display technology, with its ultimate display effect and flexible folding technology leading a "future technology" style. Foldable mobile phones, mobile computer two-in-one ultra-thin machines, curly display screens, 3D electronic printing technology, etc., one of the expectations and concepts of the future black technology have been released, and the concept machines have appeared one after another in the public eye. Although the role of OLED in the display industry is still "the future display technology", there is still a certain distance on the road of technology popularization, standard formation and product popularization.
With Apple and Microsoft in the United States announcing their plans to use OLED screens in their product lines next year, Huawei, VIVO and OPPO have decided to form an alliance to ensure a stable supply of OLED screens through localized procurement. Nowadays, OLED is also growing at an unprecedented speed in the Chinese market. Skyworth, Changhong, Konka and LG Electronics have already begun to lay out OLED TV products and achieved impressive results. The birth of completely independent OLED TV products has produced a chain effect. This marks that China's OLED TV industry has formed a complete industrial chain layout. China's OLED TV industry will no longer be just "taken" and "porters of other people's panels."
Micro LED killer perfect display
Micro LED micro-light emitting diodes are expected to become a new generation of display technology, while Micro LED is also regarded as the future killer display application, because this display technology consumes only 10% of the LCD power, color saturation is close to OLED. According to industry insiders, Micro LED is regarded as the perfect application of the new generation of display technology. At present, the international manufacturers are low-key technical layout. Once the Micro LED is commercialized, it is estimated to consume 50% of the global LED production capacity.
At present, more and more enterprises are beginning to lay out Micro LED technology, such as Taiwan's accumulation and LED factory Jingdian, Ronda; Panel Shuanghu AUO and Innolux are actively investing, and hope to accelerate the commercial production time schedule. The Taiwan Institute of Technology is optimistic that it will be available in 2017 with the Micro LED large public display.
QLED energy-saving rising star
Quantum dot LEDs, nanotechnology displays, which are brighter, brighter and consume less energy. At present, the quantum LED display adopts stable and reliable inorganic semiconductor materials to reduce the production cost, and the color purity of the display is expected to be twice that of the existing products and the luminous efficiency will be increased by 30-40%. Although QLED is superior in energy saving and emission reduction, since QLED is almost completely in the laboratory stage, we still have to wait and see how QLED display technology is.
According to the existing development status of OLED, Micro LED and QLED, it can be briefly summarized as follows; OLED is basically mature and is developing better and more extreme display; while Micro LED is at the beginning of technology, QLED is almost completely in the laboratory stage, not only can From the development of OLED to get most of the process experience, the upstream side can also get a lot of experience and capacity support from the traditional LED industry. Therefore, the future flat panel display technology can be divided into two directions: the first is to invest heavily in OLED display technology and enter the mass production mode; the second is that people are still caught in the hustle and bustle of QLED and Micro LED.
Before the OLED, Micro LED, and QLED display technologies have not been popular in the market, LED display technology is still leading the market. In particular, small-pitch LEDs have the opportunity to compete with OLEDs for the first time. In recent years, The maturity of small-pitch LED technology, facing the test of the market, only the small-pitch LED is not surprising. The small-pitch LED is not limited by its size, the display effect is good, the coverage is wide, the brightness is high, the brightness is automatically adjusted, and there is no seam. It is not subject to ultraviolet interference, and the display content is still clear when the direct sunlight is directly on the screen surface. It has a favorable position in large-screen display. When OLED is in the ascendant, Micro LED and QLED are still in the laboratory, small spacing LEDs should continue to improve technology and process manufacturing, creating a broader market for small-pitch LEDs.
The filter is an optical device used to select the desired radiation band. One of the commonality of filters is that there is no filter to make the image of celestial bodies brighter, because all filters absorb certain wavelengths, which makes the object darker.
The light of the selected waveband passes through, and the light outside the passband is cut off. The optical indicators are mainly center wavelength (CWL) and half bandwidth (FWHM). Divided into narrowband and broadband.
Short-wave pass type (also called low pass): Light shorter than the selected wavelength passes through, and light longer than the wavelength is cut off.
Long pass type (also called high pass): light longer than the selected wavelength passes through, and light shorter than that wavelength is cut off.
The filter is very useful. Widely used in the photography industry.
