Abstract: A display device including a plurality of source drivers. Each of the .plurality of source drives may include a register storing information on a bias voltage provided from the outside; a gamma voltage generation unit receiving at least one reference gamma voltage and generating a plurality of gamma voltages according to the reference gamma voltage; and an output buffer including a plurality of source amplifiers driven by the bias voltage and receiving the plurality of gamma voltages. The gamma voltage generation unit may adjust a level of at lest one of the at least one reference gamma voltage, according to a bias voltage having the lowest level among bias voltages provided to respective source drivers.

Abstract translation: 一种显示装置，包括多个源驱动器。 源驱动器的每一个可以包括存储关于从外部提供的偏置电压的信息的寄存器; 伽马电压产生单元，其接收至少一个参考伽马电压并根据参考伽马电压产生多个伽马电压; 以及包括由所述偏置电压驱动并接收所述多个伽马电压的多个源极放大器的输出缓冲器。 γ电压产生单元可以根据提供给各个源极驱动器的偏置电压中具有最低电平的偏置电压来调节至少一个参考伽玛电压中的至少一个的电平。
