PURPOSE: An overdriverable output buffer and a source driver circuit having the same are provided to allow a unit pixel to reach a desired target voltage value in a predetermined time by generating an output signal higher or lower the target voltage. CONSTITUTION: A source driver circuit(10) comprises a latch(120), a level shifter(130), a decoder(140), and an output buffer(150). The latch latches current data. The level shifter changes the level of current data. A decoder changes level-changed current data into analog data. The output buffer generates the output signal. A data comparator(160) compares the current data and the previous data. An overdriving enable part(170) controls the output buffer to perform overdriving in the enable period of an overdriving on-signal. |
