Abstract
An output compensation circuit and an output compensation method for an LCD data drive IC as well as an LCD comprising the same are disclosed. The output compensation circuit comprises a data drive IC, a plurality of first switch units and a plurality of delay control units. A plurality of output channels of the data drive IC each are connected with a corresponding row of pixel electrodes on a glass substrate via a data line respectively to output a charging signal. Each of the first switch units control the corresponding output channel according to a delay control signal generated by the corresponding delay control unit. Each of the delay control units is configured to generate the delay control signal-used to control the first switch unit to be turned on after a predetermined delay so that the charging time is the same for all the pixel electrodes.
