Abstract

A handwriting board with a liquid crystal display (LCD) includes a wireless Universal Serial Bus (USB) unit, a USB hub unit, a USB/Video Graphic Array (VGA) conversion unit, a LCD driver unit, a LCD unit, a touch pad controller unit and a touch pad unit. When a user writes on the touch pad unit, the content written by the user is transmitted from the touch pad controller unit and the USB hub unit 204 to the wireless USB unit, which transmits the written content to a computer for processing. The processed written content is then transmitted to a projector and the wireless USB unit. Thereby, the written content can be displayed on the LCD unit.
