Heavy! TCL Huaxing creates the world's first active privacy-proof ultra-thin mobile phone screen
May 5, 2022
Core Tip: Following the display of the first privacy-preventing laptop with proprietary intellectual property rights at the TCL Huaxing DTC Global Ecological Display Conference in November 2021 (which can achieve 0.46% (NVA)/10.3% (WVA) brightness at a 45° viewing angle) ratio), the technology is still iteratively upgraded, adding new elements such as thinning, new light control optical path, In-cell Touch compatibility, etc., so that the active privacy technology can be widely used in mobile phones, tablets, vehicles and other scenarios.
Screens and displays are gradually filling our lives, and the world is becoming more and more "screened". Personal privacy protection has become a rigid demand for consumers, and privacy screen protectors have emerged as the times require. Many screen manufacturers have proposed many new technology solutions for privacy protection, trying to provide consumers with a better privacy protection experience. As a technology pioneer, TCL Huaxing has been exploring in the field of anti-peep technology for a long time, providing the market with upgraded new technologies.
Following the display of the first privacy-proof laptop with proprietary intellectual property rights at the TCL Huaxing DTC Global Ecological Display Conference in November 2021 (which can achieve a 0.46%(NVA)/10.3%(WVA) brightness ratio at a 45° viewing angle), The technology is still iteratively upgraded, adding new elements such as thinning, new light control optical path, In-cell Touch compatibility, etc., so that the active privacy protection technology can be widely used in various scenarios such as mobile phones, tablets, and vehicles.
The core of the privacy screen is the precise control of the light emitting direction. TCL Huaxing has comprehensively improved and optimized in terms of design, technology, materials and overall matching, and has now entered the testing and verification stage before mass production. The most important part of privacy protection technology is to take into account the viewing angle brightness in sharing mode and the viewing angle narrowing effect in privacy protection mode. TCL CSOT has developed a dimming solution with independent intellectual property rights.
On the one hand, TCL Huaxing worked closely with suppliers to develop new materials, which greatly improved the brightness of the side viewing angle and made the sharing effect even better. On the other hand, TCL Huaxing actively updates the design and process, improves the matching between process requirements and existing designs, and meets strict reliability requirements through the most reliable process route.
The accumulation of "basic skills" has enabled TCL CSOT's privacy screen products to be recognized by the market. To become a "high-end player" in the industry, TCL CSOT will continue to capture higher technological peaks.
Starting from the actual user experience, TCL Huaxing continues to move towards lower power consumption and thinner and lighter. Thanks to the solid foundation of LTPS technology, the active anti-privacy mobile phone screen has been designed and completed. The brightness of the anti-privacy mode is ahead of the industry. Taking the 6.58-inch anti-privacy display as an example: the 45° side view brightness ratio of the anti-privacy mode is higher than that of the industry. 0.76%; 45° side view brightness ratio in sharing mode: 2.5%; 6.58-inch ultra-thin privacy-proof display’s privacy mode 45° side view brightness ratio is 1.12%; sharing mode 45° side view brightness ratio: 6.95%.
Among them, in the extremely thin and light active anti-privacy mobile phone screen solution, the overall thickness increase is far less than 0.1mm (compared to conventional mobile phone screens) while ensuring the anti-privacy effect.
Under the blessing of multiple innovative "Buffs", TCL CSOT's active privacy protection technology not only protects privacy, but also takes into account the wide viewing angle effect in the sharing mode, achieving both privacy protection and visual effects, greatly improving users user experience.
As a leading company in the global semiconductor display industry, TCL CSOT continues to improve its product capabilities through differentiated technologies. In the future, TCL CSOT will continue to deepen its active anti-privacy technology to bring more extreme experiences to customers around the world.
