Patent ID: 8125435

Claim:
A source driver applied in a chip-on-glass liquid crystal display, the chip-on-glass liquid crystal display comprising a gate driver, the source driver comprising: a receiver, for receiving a control bitstream and image data, the control bitstream having a target identity; a wave generator, for comparing the target identity with a chip identity of the source driver, wherein the wave generator outputs a source control signal to activate the source driver to convert the image data into driving voltages and transmit the driving signals to a panel of the liquid crystal display if the chip identity coincides with the target identity, and the wave generator generates a gate control signal for controlling the gate driver according to the source control signal; and a bus switch, for switching a transmission mode of the source driver between a dual-way transmission mode and a single-way transmission mode, wherein in the dual-way transmission mode, the source driver simultaneously transmits the received image data and the control bitstream to two or more neighboring source drivers, and in the single-way transmission mode, the source driver transmits the received image data and the control bitstream to a neighboring source driver.
