(54) Chip-on-glass liquid crystal display and data transmission method for the same


(57) A liquid crystal display (LCD) comprising a glass substrate, a plurality of serial-connected source drivers (212) and at least one gate driver (214), disposed on the glass substrate by chip-on-glass technology, a timing controller (225) for generating image data and a control signal, and at least one flexible printed circuit board (230,232). The flexible printed circuit board receives the image data and the control signal for transmitting to the corresponding source driver. Then the corresponding source driver transmits the image data and the control signal to the neighboring source drivers such that all the source drivers respectively get the image data and the control signal. The flexible printed circuit board is disposed such that delays and distortions of the image data and the control signal are acceptable to the source drivers e.g. by connecting to the centre source driver of the series-connected source drivers.
