Abstract

An electronic device includes a first source group and a second source group, each of which includes a plurality of source channels, and a gamma block that receives first to 2i-th initial voltages (i being an integer of 1 or more), outputs first to 2i-th intermediate voltages by amplifying the first to i-th initial voltages, and outputs first to i-th gamma voltages to the first source group by buffering the first to 2i-th intermediate voltages, and a first buffer block that receives the first to 2i-th intermediate voltages from the gamma block and buffers the first to 2i-th intermediate voltages so as to be output to the second source group, and the gamma block may include a first resistor string including a plurality of resistors connected between nodes from which the first to i-th gamma voltages are output.
