Claim:
1. A driving control device driving a plurality of pixels each pixel comprising: a light emitting element and a driving transistor connected to one end of the light emitting element, the driving transistor configured to transmit a driving current according to a data signal transmitted from a data line to the light emitting element, wherein the driving control device comprises means to obtain an actual output voltage value from a power source which supplies a driving voltage to drive the plurality of pixels and a compensation means configured to compensate for a deviation with the manufacturing driving voltage by using the actual output voltage value of the driving voltage and to generate and transmit a reference gamma voltage for forming a gray voltage according to the data signal respectively transmitted to the plurality of pixels by using the actual output voltage value, wherein the compensation means comprises: a voltage generator comprising a plurality of interconnected resistors; a decoder receiving a voltage divided in the voltage generator configured to output a predetermined first voltage, and a reference voltage output unit configured to output a voltage difference between the actual output voltage value and the first voltage as the reference gamma voltage.
