With the advancement of a new round of technological revolution and industrial transformation, new driving forces for economic development——The concept of new quality productivity has stepped onto the historical stage. New productive forces play a leading role in innovation, breaking away from traditional economic growth methods and development paths of productive forces. They possess advanced productive forces characterized by high technology, high efficiency, and high quality, and are in line with the new development concept.
New quality productivity represents the evolution direction of advanced productivity and has quietly emerged in various industries. In today's ubiquitous display industry, a new round of technological revolution and innovation is also being carried out around new quality productivity.
Currently, new display technologies represented by TFT-LCD and AMOLED are the main force in the display industry. The most mainstream display application products are still mainly mobile phones, pads, laptops, monitors, televisions, and other products, which have relatively fixed requirements for display components, materials, etc. For some non mainstream applications, personalized requirements will be put forward for panel and material factories due to different application scenarios, which requires unconventional solutions for these non mainstream application scenarios.
It is reported that the DIC AWARD 2024 International Display Technology Innovation Award has recently entered the public announcement stage, including various innovative non mainstream technologies and products.
Display device products
Among the products recently announced at the DIC AWARD 2024 International Display Technology Innovation Award, BOE (BOE) has launched the "Surface OLED Tactile Feedback" technology. This technology reproduces the real tactile sensation of different functions such as buttons, knobs, dials, and sliding bars on the display screen. In the process of the development of in car displays towards large, multi screen, and intelligent, this touch function screen can not only meet the needs of car companies for personalized products, but also improve the performance, functionality, and convenience of in car displays.
The "13 inch sliding coil" technology product declared by Tianma Microelectronics is a 13 inch pull-out OLED display screen independently developed by Tianma. This technology is also aimed at the field of in car displays, providing automotive manufacturers with a highly energy-efficient, visually appealing, and design free display platform through these innovative flexible OLED technologies. At present, there is no mass production of flexible products similar to sliding rolls on the market. This type of curlable OLED screen provides higher design freedom and better visual effects.
In terms of power consumption reduction, Vicino has applied for "intelligent partition multi frequency technology". Based on LTPO technology and devices, partition multi frequency technology divides a screen into multiple areas, with low frequency used in the static display area and high frequency used in the dynamic display area, further reducing IC power consumption. Weixinnuo completed the development of horizontally adjustable partition technology in July 2023 and produced samples, making it the first in the industry. It is expected that this technology will achieve mass production before the end of 2024, and as an LTPO 3.0 technology, it will fully occupy the high-end machine market.
From the more than 30 device technologies applied for in the DIC AWARD 2024 International Display Technology Innovation Award, it can be seen that panel companies are constantly introducing various new technologies in various aspects such as product performance, product form, production methods, and application fields. Although some technologies are still relatively niche and non mainstream, and may not be able to be applied on a large scale at present, it is not ruled out that a certain technology may become popular in the future.
Display application products
In terms of display application products, HKC Huike has applied for a "surround view rainbow screen mural TV (100 inches)". Imagine a 100 inch ultra large screen with seamless wall mural surround visual effects, which can bring visual effects comparable to OLED for high-end decoration, shopping malls and other application fields at a lower price.
The LumiFree: New Light Distribution Control Technology product declared by Japanese panel company JDI is the world's first product that uses LCD panel technology to control the light distribution characteristics of lighting fixtures in both horizontal and vertical directions. The release of this product will facilitate users to use serial port/Bluetooth according to lighting requirementsWait for the communication module to switch freely to change the lighting angle, reduce power consumption, save energy, and reduce emissions. This technology has opened up new application areas for LCD panels and provided new ideas for the business transformation of panel enterprises.
The world's first AMOLED under screen directional sound integration technology declared by Vicino is an innovative fusion of AMOLED display technology and directional sound technology. Currently, in terms of personal privacy, electronic products generally achieve anti peeping function by focusing on the perspective, while in terms of hearing, this technology can be utilized.
Display material products
In the application for material awards, Rainbow Group submitted the "G8.5 substrate glass" product. Currently, the production capacity of LCD panels in China has exceeded 230 million square meters per year, and the panel production capacity of the 8.5/8.6 generation production line accounts for 60% of the total domestic production capacity. Before 2019, domestic glass companies were unable to produce 8.5 generation substrate glass. With the support of national key research and development plans and other national special projects, Rainbow Group formed the core technology and manufacturing process of G8.5 overflow method substrate glass through independent innovation and integration. After years of efforts, production capacity has been significantly increased.
The TCFG organic enhanced non equal thickness ultra-thin glass flexible composite cover plate declared by Tuomi Group can be applied to the folding screen product market. The foldable screen mobile phone market has grown rapidly in recent years. According to statistics, the global shipment of foldable screen phones was only about 500000 units in 2019, but it has grown to 16.7 million units in 2023. It is expected to increase to over 100 million units by 2027.
The products declared by Hengmei Optoelectronics are domestically produced low permeability PMMA optical films and polarizers. At present, the production capacity of liquid crystal panels in Chinese Mainland accounts for more than 70% of the world, and the planned production capacity of domestic polarizer production line has exceeded 390 million square meters per year, which also accounts for more than 70% of the global market. The implementation of domestically produced PMMA optical films plays an important role in strengthening the procurement of domestically produced materials and reducing upstream raw material costs for polarizing film enterprises.
