In addition, Li Dongsheng commented on the Razr mobile phone, saying that "the product is still very good".

At this year's CES exhibition, TCL COMMUNICATION also showed the first folding screen mobile phone. It adopts the transverse fold design, the shape is close to square when unfolding, and the screen size is 7.2 inches. There are four cameras on the back, in green color. The folding screen phone has no name and price, and no specific release time has been announced.

Li Dongsheng said that inkjet printing technology is the next generation AMOLED process, which has not been officially put into production. This technology has the advantages of simple device structure, high material utilization, large area, low cost and flexibility. It is an important development direction of display screen in the future.

At present, TCL's inkjet printing technology is in the leading position in the world, and only Samsung, Japan's JOLED and TCL have in-depth research on the technology, according to Li Dongsheng. At the CES 2020 exhibition, TCL, in conjunction with Guangdong Juhua, also showed a 31-inch inkjet printing coilable flexible prototype, the second time TCL has demonstrated the inkjet printing process OLED technology at CES.

"The performance of this generation of prototype has been relatively perfect. The samples we made before can see some flaws. Now the performance has reached the standard of industrial finished products," said Li Dongsheng.

In addition to large-scale screen, the production of flexible screen has been restricted by printing technology. The evaporation process requires the absolute flatness of substrate, which is difficult to be used in the production of flexible screen. Ink jet printing technology is regarded as a better process for the production of flexible screen.

Li Dongsheng also imagined the production process of flexible screen in the future, that is, "roll to roll" production. The screen material is a roll, and the finished product is a roll. Such process can greatly simplify the production process, improve the screen production efficiency, and reduce the requirements for storage and transportation.
