ABSTRACT:
An electro-luminescence display device including red, green and blue reference gamma generators each having three digital analog converters or more in order to generate a reference gamma voltage of low gray level and a reference gamma voltage of high gray level, and at least one integrated circuit to generate a data signal in use of the reference gamma voltage of low gray level and the reference gamma voltage of high gray level. Each reference gamma generator includes a first digital analog converter to divide a voltage supplied to itself in order to generate i numbers of voltage levels, a second digital analog converter to divide a voltage supplied to itself in order to generate j numbers of voltage levels, and a third digital analog converter to receive two voltage levels from the second digital analog converter and to divides the two received voltage levels into j numbers of voltage levels.
