Apparatus and method for driving organic light emitting display device

摘要

Disclosed is an apparatus and method for driving an organic light emitting display device which facilitates to control current consumption of a display panel according to a temperature of the display panel including a light emitting device or a surrounding temperature of the display panel, the apparatus comprising the display panel including the plurality of pixels provided with the plurality of light emitting devices which emit light according to a current, a temperature sensing unit for generating temperature data by sensing a temperature of the display panel or surrounding temperature; and a panel driver for controlling a data signal to be supplied to each pixel so as to make current consumption of the display panel be lower than a preset current limit value on the basis of input data and temperature data.

1. An apparatus for driving an organic light emitting display device comprising:
a display panel including a plurality of pixels provided with a plurality of light emitting devices which emit light according to a current; a temperature sensing unit that generates temperature data by sensing a temperature of the display panel or surrounding temperature; and a panel driver that generates a frame current value of one frame by the use of input data and temperature data, generates a current limit gain value for controlling the current consumption of the display panel be lower than the preset current limit value based on the frame current value, and controls a data signal to be supplied to each pixel based on the current limit gain value.
