LTPS technology is slowly penetrating into the display field. This technology will be a huge controversy with OLED technology. When producing LTPS and OLED products, the yield has always been the biggest problem in the industry. It seems as if the physical index tolerance of the display changes overnight. However, LTPS technology is currently recognized by the industry, and its addition or acceleration of display technology replacement.
After Apple introduced LTPS technology to the field of mobile phone display, the technical perfection and quality control of the display gradually surpassed the traditional engineers' business ability. It seems that the physical index tolerance of the display changed overnight, and it is difficult to use a fixed one. Entity detects data to control.
It is also starting from the industry's re-recognition of LTPS technology, the process control of the display screen, and also from the simple PCB-type result detection and control, back to the semiconductor workers' front physical size control. In view of the late display effect detection and control, in addition to the semiconductor industry, like the semiconductor industry, the panel quality correction and picture rewriting technology introduced by Apple have been used by the industry and become the panel factory to rescue the display yield. Important weapon.
In fact, not only in the LTPS technology, the image quality correction and picture rewriting technology that Apple relies on has been quickly recognized by the industry, and has been learned, optimized, and incorporated into its own products by the driver IC factory and the testing equipment factory. It brings great convenience to the panel industry to control quality, improve yield and improve process, and it is also indispensable in the application of OLED display correction and compensation technology.
Compared with traditional ITO technology and a-Si technology, LTPS technology is closer to the real modern semiconductor process, and OLED display technology can be fully integrated into the modern semiconductor category, because the core theory of these technologies is in the ion doping technology. Dynamic ion concentration control and migration control are geometrically improved compared to the classical static ion doping concentration control difficulty. This also fully explains why the industry has been the biggest problem in the industry when producing LTPS and OLED products.
Apple's image quality correction and picture rewriting technology not only opened another door for the display industry to learn from the semiconductor technology, but also changed the random physical parameters that were difficult to tame in the original industry, and passed the detection, correction and rewriting to unified standardization. At least 20% to 30% of the industry's yield, but also let the production line engineers get rid of the endless "everyday fortune-telling" work, no need to go to the statistics and comparison work of the pre-physical parameters and the post-test data. It is to give this all to the testing equipment to complete.
Moreover, with the deeper and deeper artificial intelligence intervention of the detection, correction, compensation and feedback control software of the driver software and detection equipment, a lot of work on the panel production line will be fully automated, and the database model generated by artificial intelligence will replace Most of the production line engineers have become the actual execution units for technical and quality control of panel production lines and module processing plants.
In a sense, the software will smooth out too many technical barriers to show the production process of the enterprise. The essence of market competition will quickly return to capital investment and hardware research and development. The breakthrough of core technology theory and the breakthrough of technical mass production will Return to the core of industrial progress. This also means that the industry's engineer bonus will lead to the upgrade of the open-loop semi-automation industry, which will replace the current employee bonus. The closed-loop fully automated industrial upgrade guided by the future industry's artificial intelligence dividend will completely replace the current engineer dividend. .
Did you find that this situation is the same as that of the industrial system of the developed countries earlier? It is the people who produce the building blocks and teach people to play with the building blocks, and the people who build the different products by building blocks, and finally earn more than ten or decades. Money was lost all night during the industrial transfer. This is the case with home appliances, the same for making cars, and the same for ships and planes.
It seems that the entire industry is going back to the 1990s, which was the beginning of the industry's outbreak, the stage that relied on the original theoretical innovation and software technology breakthroughs, the equipment manufacturers with breakthroughs in core technology and the software vendors with algorithms and code standards. Become the main force in the direction of the leading industry.
