Recently, the HDMI Committee announced the launch of a new generation of HDMI*Type D connectors (also known as micro HDMI connectors) to meet the digital interface requirements of consumer electronics products. The HDMI*Type D connector is the industry's first miniaturized connector solution to transmit high-definition video and images from mobile devices to flat screens. The connector can meet all the electrical and mechanical specifications in the recently released HDMI Specification 1.4, which will greatly benefit the digital video camera and mobile device markets. The new Type D (miniature) connector is about half the size of the Type C (MINI) HDMI connector currently on the market. Despite its smaller size, the new Type D version has equivalent mechanical strength and electrical characteristics. Mobile phone and consumer product customers have expressed strong interest in this new technology that allows users to display clearer videos, photos and other content from mobile devices on full-size flat-screen TV screens. Adapt the new HDMI*Type D micro connector design to the needs of portable devices and provide these products with a fully functional smaller 19-pin connector. the
