Abstract:
1. A liquid crystal display having a conversion board for receiving an outside power supply and a digital data signal including a dot signal, wherein the conversion board comprises: a digital signal receiver for receiving the outside power supply and the digital data signal including the dot signal; and a comparator for comparing whether a frequency of a dot signal is higher than a frequency used in a driving device for the liquid crystal display or not, wherein, when the frequency of the dot signal is higher than a minimum frequency capable of operating a timing controller or a driving device, the frequency of the dot signal is divided by 2, the 2-divided signals are outputted through two channels and the digital signal is applied to a module of the liquid crystal display by means of the two channels, and when the frequency of the dot signal is lower than the minimum frequency capable of operating a timing controller or a driving device, the dot signal is outputted through one channel and the digital signal is applied to the module of the liquid crystal display by means of one channel.
