Thanks to the technology accumulation in the ltps-lcd field in the past, TCL China Star announced two epoch-making LCD technologies: under screen camera technology and LCD on-screen fingerprint technology.
In the past, the off screen camera and in screen fingerprint technology need to use AMOLED panel as the carrier. Due to the high cost of AMOLED panel, these two technologies can not be popularized in the low-end models. The two technologies developed by TCL China star can rely on LCD panel as the carrier, and at the same time, the performance is not inferior to the same type of products equipped with AMOLED panel.
LCD off screen camera, using the off screen camera solution independently developed by TCL China Star, is the first LCD off screen camera solution in the industry, which realizes real full screen display and conforms to the current development trend of full screen. This technology adopts a unique backlight structure and a new pixel design, which can realize the free switching between display and photo taking, taking into account the needs of both display and photo taking. It can not only achieve a better overall screen display effect, but also optimize the photo taking effect of the front camera, greatly improving the users experience.
It is worth mentioning that TCL China Stars off screen camera technology has been very mature and has the conditions for mass production. A month ago, Lei Jun, chairman of Xiaomi group, released the third generation of off screen camera technology on Weibo. The official micro blog of TCL China Star Co., Ltd. forwarded Lei Juns Micro blog, which is a side confirmation of the cooperation between the two sides. The announcement of under screen camera technology based on LCD panel will further popularize this technology.
In addition, TCL China Star has developed the double fold display technology and cross fold display technology following the hottest folding screen technology. The 7.2-inch cross fold display sample displayed at the meeting is the first flexible display terminal that can realize multi-directional bending.
In the field of medium size, TCL China Star has released two products: 13.5-inch WQ dual screen display screen and 15.6-inch ltpo display screen. Among them, the 13.5-inch WQ display screen adopts high-end in cell display, which is the first time in the industry to apply this technology to dual screen display. The 15.6 inch ltpo display screen realizes 5-360hz frequency switching. The screen can automatically identify the use scene and adjust to different frequencies to achieve the effect of energy saving and power saving.
In addition to breakthrough new technologies, TCL Huaxing also has demonstrated a number of innovative technologies leading in medium and small-sized industries, such as 2.4mm full screen technology which can shrink the lower frame of the module to the smallest in the world, and static tensile and impact resistant technology that can withstand 50kgf pull.
Behind these technologies is the concentrated embodiment of TCL CStars continuous overweight layout in the field of medium and small size for more than ten years. The T3 production line located in Wuhan is the first small-size panel production line of TCL Huaxing, and also the first sixth generation LTPS display panel production line in China. In less than two years, this production line has successively overcome the industrial problems such as blind hole, irregular cutting, extremely narrow frame, etc.
Since then, through technical transformation and equipment expansion, the production line will become the largest LTPS monomer factory in the world in 2019, and its market share will remain the second in the world. At present, Wuhan Huaxing T3 production line with finepixel (eagle eye), iest (intelligent power saving), CPLP (circular polarization), low blue light and other self-developed technologies, occupies an important market share in the field of small and medium-sized LTPS panel, and its 93% product yield is at the top level in the industry.
The T4 production line, which started later, is the sixth generation AMOLED flexible production line. At the beginning of its construction, this production line has become the first in many industries. It completed the construction of the production line in less than one year after the start of construction, and completed the shipment of brand customers in less than one year after the lighting of the products. At present, the first phase of T4 production line has achieved full production, and the second and third phases are under construction. TCL technology has estimated in its semi annual report that after the completion of T4 production line, it can achieve an annual output of 1.16 million square meters of AMOLED panels, which can meet 5% of the global demand for AMOLED smart phone panels.
The differentiated technology of T4 production line is widely praised in the industry chain. Its technology path includes off screen camera, extremely narrow frame, folding and other cutting-edge products. These technologies are also carried on the flagship products of Motorola, Xiaomi, Lenovo and other large terminal manufacturers. The shipment volume of the top six mobile phone brand customers in the world accounts for 80%. Many star products of TCL China Star come from this product line. From TCLs three fold screen mobile phone which was unveiled on CES last year, to AMOLED screen with small aperture on Xiaomi flagship device, and cloud scroll screen mobile phone with automatic pull-out design, TCL Huaxing has expanded the industrys application and imagination for small and medium-sized products. In the future, the field of small and medium-sized AMOLED will still be the key layout direction of TCL China Star. At the meeting, Jin Mingzhi, senior vice president of TCL technology and CEO of TCL China Star, said, TCL China Star will continue to develop flexible, curlable and foldable technologies around flexible display.
