Analysis of the possible competitive relationship

Analysis of the possible competitive relationship between various technologies in the display and lighting industry

"have you OLED?" It is said that this simple greeting has become the international etiquette of the panel industry. Display expert Jiong Snow once said sincerely: if there is anything more popular than iphone7 recently, it is OLED evaporation machine

oled is undoubtedly the rock star in the display industry in 2016. So what charm does this star rely on to conquer the display industry? Does other technology have the power to compete with it? Today's recommendation: from Mr. Liu Guoxu, the chief technology officer of Yimei core light, 3. The measured hardness value and the indicated value of standard hardness block are different from each other in the display and lighting industry, and the possible future competition relationship analysis

in addition, the portal of "OLED frontier knowledge collection" is attached at the end of the article. Among them, a Xiongwen has been widely introduced into the display world, and the real reading volume is close to 60000

don't talk about the correct nonsense. First, let's go to Mr. Liu Guoxu's concise answer -

how to treat the competitive relationship between OLED, qled, micro led and laser in the future

oled should have obvious advantages in small screen mobile communication. However, in large-scale TV applications, its yield and stability are difficult to improve, and the cost has been high. The core patents of this technology in large and small screens are in the hands of LG and Samsung respectively, including high-end devices with limited capacity. Therefore, several new display technologies have attracted the attention of the industry recently, including qled, microled and laser display you mentioned

quantum dots (quantum dots) are divided into pl (photoluminescence) and EL (electroluminescence). At present, QD TVs that have been mass-produced still belong to photoluminescence, which is an extension of LCD backlight technology. By using the narrow half peak width and wavelength adjustable characteristics of QD, it can replace the traditional phosphor to achieve a wider color gamut display

qled refers specifically to electroluminescence. Both OLED and OLED belong to active luminescence, and backlight is no longer required. One is mainly inorganic materials, the other is all organic materials. Qled is cheaper than OLED and can be made by printing, spraying and other technologies to replace the vacuum evaporation necessary for OLED. Color gamut and energy efficiency are also better than OLED. However, this technology still needs a long time of material research and equipment development, and it is expected to achieve mass production in the next five years

microled is also active light-emitting. When the size of RGB tricolor LED is reduced to micron level, such as micron, each pixel can be addressed and controlled and single point driven light-emitting. Due to its high brightness, it is suitable for outdoor wearable display; Its nanosecond switching speed [supplement: LCD (including LED backlight) is in milliseconds, OLED is in microseconds, and microled is in nanoseconds. In applications such as watching sports pictures or playing games at close range, as well as AR, the slow response. Below, our technicians will introduce the characteristics and ordinary protection of digital display electronic tensile testing machine; the speed may produce blurred pictures, which is easy to cause adult dizziness and other problems] is more suitable for ar/vr applications; And its advantages such as high brightness, low power consumption, color saturation and high black-and-white contrast are suitable for Xinlun Technology (002341, Guba) to announce that it is suitable for large-scale display. At present, the supply chain of microled, an emerging technology, has not been completely constructed, and chip on submount testing, mass transfer process, cross talk light leakage and bonding equipment need to be developed and improved. Recently, many led and display companies have begun to invest a lot of money. It is reported that apple and Sony will launch consumer products using microled displays within a year or two

the application of laser in display is mainly in the form of laser projection. Small portable or large cinema projection has achieved mass production. At present, the research and development direction is mainly to improve the RGB Laser power, especially to improve the lack of green light. Another technical route uses blue laser to excite phosphor, and makes the projector smaller from an optical point of view, with better projection effect and wider color gamut. Driven by the rapid development of national strategic emerging industries, the above technologies are mainly used in the display field, but they will also be applied in some lighting fields, such as OLED lighting we have seen. In contrast, laser phosphors are the most promising in lighting. Laser lighting has been applied to car headlights, because its illumination is hundreds of times higher than that of LED headlights. At the same time, it is smaller, more energy-saving, longer irradiation distance and stronger ability to penetrate fog. It is reported that BMW has a laser lighting system on its I8 concept car. For this reason, Nobel laureate Xiuer Nakamura promoted the technology and application of laser lighting on different occasions
