日期:2018-04-12   类型:Industry information

On April 10, 2018, the sixth China Electronic Information Expo (CITE 2018 for short) jointly hosted by the Ministry of Industry and Information Technology and Shenzhen Municipal People's Government was in full swing in Shenzhen Convention and Exhibition Center. CITE, as an annual event of electronic information industry with leading industry, complete industrial chain, the largest scale in Asia and international influence, has held six sessions so far.


CITE 2018 covers an area of more than 100000 square meters. The exhibitors include leading enterprises in the industry, such as Haier, BOE, Konka, LGD, and a total of more than 1200 exhibitors. With the theme of "smart lead in a new era, smart enjoy a new life", the Expo focuses on displaying and interpreting the latest achievements and trends of China's electronic information technology development, which will effectively promote the vigorous development of the "the Belt and Road" electronic information industry.


According to WitsView editor, the exhibition area of display panel industry is Hall 2 and Hall 1 (part), mainly including LCD, OLED, quantum dots, laser display exhibition area, equipment, materials exhibition area, smart phones and other exhibition areas, covering the production, technology and application fields related to panel LCD and OLED industries, including devices, equipment, applications, etc.


Leading enterprises at home and abroad, such as BOE, Vicino, LGD, Huike, JDI, Hehui Optoelectronics, Tianma, Longteng, Huaxing, and Zhongdian Panda, all appeared. According to the on-site atmosphere, the editor of WitsView found that flexible OLED technology is the most popular one. Basically, every exhibitor has displayed flexible OLED screen equipment, and many spectators have gathered to experience and listen to the explanation.


As we all know, flexible OLED is known as the next generation display technology in the panel industry and one of the most important innovative technologies in the industry. Compared with existing LCDs, OLEDs have higher contrast, wider color gamut, lower power consumption, and faster response speed. The most important thing is that they can achieve flexibility, bending, and folding, which will be a display technology leading the trend in the future. Since the appearance of OLED technology, domestic and foreign manufacturers have begun to deeply study the layout of OLED field. Up to now, the slogan of LGD in this exhibition is: OLED, the general trend has been achieved.


Visionox


In this exhibition, with the theme of "softness without boundaries", Vicino demonstrated its success in many aspects of the flexible AMOLED industry, and demonstrated its products, which are known as "the world's first 7.2 inch roll screen concept machine", "3.35 inch flexible display smart wearable phone", "flexible display e-book", "Notch AMOLED full screen", "flexible AMOLED full screen" and so on.



It is understood that as early as December last year, Vicino released the product of "flexible screen full module with arbitrary folding", which is the world's first folding flexible screen module product, with an internal bending radius of 3mm and an external bending radius of 5mm. The bending times exceeded 100000, and it is the world's leading technology level.


This exhibition has brought more perfect and advanced flexible display technologies. Breakthroughs in these technologies will bring innovative changes to intelligent terminals in the future, and flexible OLED displays will also achieve a new leap. The editor of WitsView learned from the on-site Vicino staff that as a new display technology, the road of flexible OLED is not smooth. The challenges of flexible OLED in the industrialization process come from three aspects: the difficulty of OLED technology, the lack of appropriate materials in the upstream, and the uncertainty of the downstream end product form.


BOE


BOE, as the leader of domestic panel enterprises, achieved mass production of 6-band lines last year, and the flexible OLED field is catching up with the Korean manufacturer Samsung/LGD step by step. BOE also showed many AMOLED products at the same time,



Among them, the coolest is the 7.56-inch foldable OLED display, whose resolution has reached the QXGA level. LTPS process and film packaging technology are adopted, which can realize flexible dynamic bending of products with bending times more than 100000 times, QXGA resolution (2048x1536) flexible AMOLED folding display, and the radius of curvature is only 5mm.


In addition, BOE also displayed a 6.2 inch WQHD special-shaped full screen and a 5.5 inch QHD flexible wristband AMOLED display.


Tianma


As the most competitive representative of China's display industry, Tianma has also been invited to participate in the exhibition for six consecutive years. At this exhibition, Tianma also brought its scientific research achievements in the OLED field, bringing us a "wonderful vision".



One 5.99 inch WQHD+flexible notch display screen was first introduced in China. It uses flexible AMOLED technology and has the characteristics of bending, ultra-thin, anti fragmentation, excellent display, etc. It can achieve the effect of bending under a 3mm radius of curvature, and the resolution reaches WQHD+(2880 × 1440).


This product has broad market prospects in emerging fields such as curved display terminals, wearable devices, scalable display devices, etc. In addition, Tianma also demonstrated the Notch screen ultra narrow frame technology. By using the screen circuit design limit compression and ultra narrow backlight solution, the ultra narrow lower frame can be achieved to achieve the best visual experience.


Hehui Photoelectric


As a high-tech company, Hehui Optoelectronics focuses on mass production of small and medium-sized AMOLED displays and research and development of next-generation display technologies. It has expanded the application field of flexible AMOLED, focusing on the display of smart phones, wearable, car mounted, VR and other flexible screen products.


Among them, the most sci-fi is the 5.5 inch AMOLED flexible curly screen and folding screen, with a pixel density of 402ppi and a resolution of 1080 × 1920, total thickness 0.2mm. The curling radius of the folding screen shall reach 3mm, and the curling radius of the curling screen shall reach 5mm.



Folding and crimping are the key development direction of flexible display at present. Foreign panel manufacturers have laid out here for a long time, but they have not really achieved mass production. The display of these samples also represents that the flexible display technology of Hehui Optoelectronics has been in a leading position in the international market and the domestic market.


In addition to these manufacturers, other enterprises such as LGD, JDI and Huike also brought many eye-catching products and advanced technologies. Some regret that Samsung was not seen in the exhibition.


Looking at this exhibition, we can see that with the acceleration of the intelligent wave, the complementary display industry has also made new breakthroughs in technology and market. Especially under the guidance of the trend of smart phones, the flexible AMOLED screen has become the hot spot at present. In the future, flexible display technology will be the key to the innovative transformation of intelligent terminals, and will lead the trend of intelligent terminal applications. At the same time, it is also expected that domestic manufacturers can courageously catch up with Korean enterprises in new technology fields, and realize the glory of Made in China.
