The slim pen features lightweight and low power consumption, 1024 levels of pressure sensitivity, precise and instant response, and hovering preview. In addition, Waltop provides exclusively developed customized stylus application and a comprehensive design reference kit which supports multiple transmission protocols to enable device makers implement Waltop solution from kick-off to mass production in two months to match the critical market timing. Customers using Waltop solution have successfully designed on Qualcomm, MTK, and Spreadtrum platforms; leading tablet manufacturers in Taiwan, as well as China’s first-tier handset brands and solution providers have also adopted Waltop solution on their products that are in mass production.
