Source drive integrated circuit, method of manufacturing the same, and display apparatus including the source drive integrated circuit

A display apparatus comprising:

• a display panel including a plurality of gate lines and a plurality of data line, which are arranged to intersect one another and thereby define a plurality of pixel areas, and a pixel provided in each of the plurality of pixel areas;
• a gate driver sequentially supplying a gate signal to the plurality of gate lines;
• and
• a data driver supplying data voltages to the plurality of data lines and comprising a source drive integrated circuit (IC),
• wherein the source drive IC comprises:
• a core portion;
• a first channel portion disposed outside one side of the core portion to receive data corresponding to a digital image signal from the core portion to output a data voltage corresponding to an analog image signal;
• a second channel portion disposed outside the other side of the core portion to receive data corresponding to a digital image signal from the core portion to output a data voltage corresponding to an analog image signal;
• a first resistor string provided inward from the one side of the core portion to generate a plurality of gamma voltages;
• a first resistance corrector provided between the first resistor string and the first channel portion;
• and
• a first connection line extending from the first resistor string to each of the first channel portion and the second channel portion and transferring the plurality of gamma voltages to the first channel portion and the second channel portion,
• wherein the first connection line is connected to the first channel portion via the first resistance corrector.

A method of manufacturing a source drive integrated circuit (IC) including a core portion, a first channel portion disposed outside one side of the core portion, and a second channel portion disposed outside the other side of the core portion, the method comprising:

• a process of forming a first resistor string inward from the one side of the core portion and forming a first resistance corrector between the first resistor string and the first channel portion;
• a process of forming a first connection line extending from the first resistor string to the first channel portion via the first resistance corrector and extending the first resistor string to the second channel portion;
• and
• a process of correcting a resistance of the first resistance corrector.
