Data signal generator and display device including the same

A display device comprising:

• a gate driver configured to output a gate control signal;
• a data signal generator configured to output a data signal;
• a plurality of gate lines controlled by the gate control signal;
• a plurality of data lines to which the data signal is output;
• and
• a plurality of pixels each connected to a respective one of the plurality of gate lines and a respective one of the plurality of data lines,
• wherein the plurality of data lines include a first data line and a second data line,
• wherein the data signal generator includes:
• a grayscale data generator configured to output a plurality of data signals including a first data signal and a second data signal;
• an input data comparator configured to output one of a first control signal and a second control signal according to a condition, based on the first data signal and the second data signal;
• a first output unit configured to receive one of the first control signal and the second control signal and the first data signal, and to output a first output data signal to a first data line;
• and
• a second output unit configured to receive one of the first control signal and the second control signal and the second data signal, and to output a second output data signal to a second data line,
• wherein the condition relates to
• a change between a first previous data signal input to the first data line and a second previous data signal input to the second data line from the grayscale data generator in a previous line-time, and
• the first data signal input to the first data line and the second data signal input to the second data line from the grayscale data generator in a current line-time,
• wherein the first control signal causes the first output unit and the second output unit to perform a first operation, and
• wherein the second control signal causes the first output unit and the second output unit to perform the first operation and a second operation.
