Patent ID: 7518600

Claim:
A driving apparatus of a liquid crystal display, comprising: a liquid crystal display (LCD) panel; a drive system for setting a channel type that indicates one of a single channel and a double channel and transmitting a plurality of signals having TTL levels to drive the LCD panel; an interface part that generates a channel mode signal having the channel type and converts the plurality of signals having TTL levels into a plurality of low voltage differential signals in accordance with the channel type, the interface part including a first connector for outputting the low voltage differential signals and the channel mode signal having the channel type; and a timing controller that receives the low voltage differential signals and the channel mode signal having the channel type through a second connector, converts the low voltage differential signals into a plurality of transistor-transistor logic (TTL) signals in accordance with the channel type of the channel mode signal, and transmits the plurality of TTL signals to gate and data drivers of the LCD panel, wherein an arrangement of the LVDS signals transmittable by pins of the first connector is altered in accordance with the channel type.
