S SERIES SMARTWATCH SOLUTIONS A range of smartwatch solutions for square screens With a (1.3',1.69',1.72',1.75',1.78',1.81,1.83',1.85',1.91',1.95',1.99',2.0') square TFT color screen with resolution of 240x280/280X328 pixels and a pixel density of 218 ppi, this screen became available on a large scale by the end of 2020 and is now offered at a low cost. It has a 7:6 aspect ratio (better than the previous mainstream 1:1 ratio) and 5 mm radius in the four corners of the screen. This design is ideal for use on square smartwatches with a more coordinated scale and a rounded design that matches the four rounded corners of the smartwatch for a better screen experience. The S Series is a range of smartwatch solutions based on the Nordic nRF 5340, Nordic nRF 52840,Realtek 8763E, Data-based UI Design For the UI design of the S series smartwatch solution, we wanted to make it more efficient for users to get more information on a limited screen space. So, we targeted to minimize visual effects and focus our design efforts on the presentation of data. In terms of visual effects, we have designed many small effects with high-quality details to enhance the presentation of data. In the S series smartwatch solution, users can get rich health and exercise data on their watches without having to turn on their phones every time to see them. Finer Dynamic Design Although mentioned earlier that in the S series smartwatch solution we did not do as much visual design as before and instead focused on data rendering, we also put a lot of effort in visual design, as we included a lot of small dynamics to aid in data rendering. We relocated all the small icons of the characters in motion mode, re-modified it to include the shape of the characters at different angles,...

Smartwatch solutions for Round screens

V SERIES SMARTWATCH SOLUTIONS A range of smartwatch solutions for round screens The Round Screen(1.28',1.32',1.39'1.45'1.59') circular TFT color screen has a resolution of 360x360 pixels and a pixel density of 273 ppi, higher than the current majority of regular smartwatch screens. This screen started being sold on a large-scale market at the end of 2020. In addition, the cost has been kept to a lower level. Because the chip position under the screen is optimized so that the screen’s outer circle diameter appears small, the structure in the circular smartwatch is able to achieve higher space utilization, while the appearance is one of a larger screen. The V Series is a range of smartwatch solutions based on The Nordic nRF 5340, Nordic nRF 52840,Realtek 8763E, and Goodix 5515 platforms for customers with this screen. New Rudder Navigation In the UI design of the V series smartwatch solutions, we've done a greater iteration to visually transform the entire UI. Based on the V series' higher definition, faster-response TFT screen, we've designed a new main navigation menu, Rudder Navigation. All icons are circled around the edge of the screen to become "rudder wheels” while the center area displays a large selected icon. By swiping your finger at the edge of the screen, you can spin the "rudder wheel" to have different function or icons selected. "Rudder navigation" has a higher playability, better visual exposure, as well as a smoother interaction experience, with a natural high degree of integration with the round watch. 3D Icon Design For the visual design of the V series smartwatch solutions, we investigated the direction the design of visual presentation was heading in the industry today. We concluded that Microsoft's new material design concept in 2019 along with Apple's macOS Big Sur system on display at WWDC in...

Smartwatch Solution

Smartwatch SolutionTo Realize More Features, Longer Operating Time and Smaller Size Smartwatch, which is large and charge is frequently required, is not smart? Designing the power supply circuit of mobile devices for wearable applications, such as smartwatch, is to solve many technical problems to realize the customers’ high expectations. Reduction of the current consumption and the frequency of battery charging can be realized by using advanced and high-performance power management ICs. In addition to these power management ICs is contributing to the evolution of mobile devices by providing operational amplifiers for amplifying sensor signals, a key feature of mobile devices, as well as high-performance and small size package discrete products such as MOSFETs, TVS diodes (ESD protection diodes), SBDs, and transistors. Features Power Management In the design of the charging circuit, not only the realization of reliable control, whether for wireless charging or charging with a cable, but also the protection of the circuit from unexpected short-circuits of the power supply, external noise such as EMI, and other abnormal conditions are required. For power management in the later stage circuit from PMIC of integrated power supply ICs, modules such as sensitive sensors and chipsets may have higher performance requirements for power supply. The LDO regulators and load switch ICs deliver high performance with minimal current consumption and are packaged in small wafer-level chip-scale packages.
