Aac Technologies : “Black Technologies” Presented at 2019 Technology Seminar of AAC - Technical Innovation Empowering Diversified

As is well-known, the global smartphone market faced with a number of challenges in the last 2 years. Improving the product competitiveness has become the only way for the smartphone brands to win, and it is particularly important to accelerate technical innovation and optimize industrial design. AAC analyzed the five trends and challenges for the future development of mobile phone, and proposed several innovative solutions at the seminar.

One of the most important tends is the full screen. Smartphone has been evolving to expand the screen area in order to maximize the display for the immersive contents and interactions, but it is faced with the challenge of how to minimize the frame and maximize the screen aspect ratio.

Therefore, AAC developed the advanced shape surface treatment technology based on 3D glass. The 3D formation technology is suitable for both the front cover and the rear cover of mobile phone, and features multiple CMF technologies. It can realize special design. In addition, to remove the 'notch' and realize true full screen, AAC developed stepping motor module with the proprietary electromagnetic drive technology. It has become the only provider of vertical integrated solution in the world.

In addition, more and more smartphones have begun to adopt 3D curved screen, and the number of physical buttons is reduced constantly. With the popularity of mobile game, there is an urgent need to improve the tactile feedback of the user experience. Therefore, AAC developed Haptics high performance vibration motor, whose virtual button solution can provide multiple customized inputs, such as press, slide, multiple clicks and multiple gestures.

In addition, the requirement on the camera function of the smartphone is increasing quickly. The consumers demand for better front and rear cameras, better resolution and color calibration, as well as other advanced performance, such as zoom, beautify, image processing, etc. To improve the user experience, AAC has offered one-stop solutions, including multi-cam and multi-cam + ToF solution, bigger optical lens, bigger sensors, and new motor to enhance the alignment and calibration functions.

With the development of media, the users require better audio experience. It is a big challenge to increase the screen area and reduce receiver footprint without compromising the sound quality. Therefore, AAC developed the new generation screen sound technology, which not only eliminates the receiver holes, but also ensures superior sound quality. In addition, the SLS technology developed by AAC can realize lower frequency and more immersive and realistic sound effect by increasing the amplitude. Its mature dual speaker solution can realize powerful stereo sound effect.

5G is the biggest hot topic in 2019. The quick increase of transmission speed also means 3 challenges in the antenna field: installing more antennas, covering more frequency bands, and combining more frequency bands through carrier aggregation. Therefore, AAC has made great effort to develop high-performance LCP interconnect in 5G RF field, which can be jointly designed and integrated with the structural parts to realize higher consistency in the system assembly.
