Thank you, Mr. Air, a netizen of CTOnews.com, for your clue delivery! CTOnews.com, September 20, according to the official account of Tianma Microelectronics, Tianma launched a new generation of CFOT technology for OLED screens, which can meet the needs of long-term mobile phone life, screen bending, screen color reality and so on.

The full name of Tianma CFOT technology is Color Filter On Touch. In short, the R & D team developed CFOT technology to replace the polarizer in the OLED screen structure.

In the OLED screen structure, the polarizer is an opaque plastic sheet to prevent external light from interfering with the screen display. Without the anti-reflection effect of the polarizer, the OLED screen will reflect light like a mirror. On the other hand, when the OLED screen self-illuminates through the polarizer, the light brightness will decrease by more than 50%, resulting in high power consumption. Instead of polarizers using CFOT technology developed by Tianma, officials say the light transmittance can be increased by more than 30%, and the panel power consumption can be reduced by more than 25% (measured values).

Comparison of screen Power consumption of Tianma CFOT Technology

Tianma officially said that with Tianma's breakthroughs in innovative technologies such as HTD and MLP, with the integration of the three technologies of HTD+MLP+CFOT, the power consumption of the entire console panel based on related application scenarios can be greatly reduced by more than 30%. Consumers can not only enjoy the smooth experience of the 1Hz-120Hz intelligent dynamic refresh rate screen, but also ease the worry about the lack of power on their mobile phones.

In addition, another innovative advantage of Tianma CFOT technology is to significantly improve the folding and crimping performance of the flexible screen. When the ordinary flexible folding screen is bent repeatedly in the market, there is often the problem of peeling off the film under the polarizer. Using CFOT technology to replace polarizer can not only solve the problem of peeling failure of rubber material mentioned above, but also reduce one layer of plastic and one layer of glue, thin the laminated size of the screen, achieve the ultimate bending radius, and pass more than 200000 bending tests.

Tianma showed an ultra-thin stacked screen equipped with CFOT technology at the SID2022 exhibition, which can be crimped more than 100000 times through the design and adjustment of materials and glue.

In addition, Tianma CFOT technology not only improves the light transmittance, but also further improves the color gamut of the screen, which can experience the natural color at the film level of the super-visual net. According to officials, the NTSC color gamut of screens integrated with CFOT technology is 15% higher than that of screens with polarizers, making it an industry leader. The screen color display is more realistic and natural, and the color purity and color expression are better than the traditional OLED screen.

CTOnews.com learned that Tianma's new generation of CFOT technology can be widely used in folding mobile phones, cars, notebooks and future curly flexible display products.
