Electroluminescence display apparatus reducing number of gate lines in double rate driving

An electroluminescence display apparatus comprising:

• a first pixel;
• a second pixel disposed adjacent to the first pixel in a horizontal direction to share a data line to which a first data voltage and a second data voltage are time-divisionally supplied and a reference voltage line to which a reference voltage is supplied, along with the first pixel;
• a first gate line coupled to the first pixel to transfer a first gate control signal, corresponding to the reference voltage, to the first pixel;
• a second gate line coupled to the first and second pixels in common to transfer a second gate control signal, corresponding to the first data voltage and the reference voltage in common, to the first and second pixels;
• a third gate line coupled to the second pixel to transfer a third gate control signal, corresponding to the second data voltage, to the second pixel;
• a gate driver coupled to the first to third gate lines;
• and
• a data driver coupled to the data line,
• wherein each of the first and second gate lines has a first line width, and the third gate line has a second line width which differs from the first line width,
• wherein
• the gate driver generates the first gate control signal to supply the first gate control signal to the first gate line, generates the second gate control signal to supply the second gate control signal to the second gate line, and generates the third gate control signal to supply the third gate control signal to the third gate line, and
• the data driver synchronizes the reference voltage, which is to be supplied to the first pixel, with the first gate control signal having an on level to supply the reference voltage to the reference voltage line, partially synchronizes the first data voltage, which is to be supplied to the first pixel, with the second gate control signal having an on level to supply the first data voltage to the data line, synchronizes the reference voltage, which is to be supplied to the second pixel, with the second gate control signal having an on level to supply the reference voltage to the reference voltage line, and partially synchronizes the second data voltage, which is to be supplied to the second pixel, with the third gate control signal having an on level to supply the second data voltage to the data line.
