Abstract
The invention discloses a high definition video and audio output mode and display equipment implementing the same. Mobile high-definition link (MHL) signals output by a mobile are transmitted to a mobile high-definition link-high-definition multimedia interface (MHL-HDMI) conversion chip through an MHL joint, and then high definition MHL signals of 1080 pixels are converted into standard HDMI signals. Meanwhile, the MHL-HDMI conversion chip can perform consumer electronics control (CEC) with mutual communication together with the mobile in order to facilitate the switch between audios and videos of the mobile. The HDMI signals can not directly lighten a liquid crystal display screen and accordingly are transmitted into a display drive chip which converts received the HDMI signals into low voltage differential signaling (LVDS) signals. The LVDS signals are transmitted to a display screen. The high definition video and audio output mode and the display equipment implementing the same can be widely applied in the switch and transmission of videos and autos of mobiles and display screens so as to display videos of a mobile memory in a larger display screen and produce a better watch effect.
