Display device and control circuit for a light modulator |
摘要 |
The invention relates to an active-matrix image display device that comprises an array of light emitters. Each light emitter is controlled by a current modulator having a particular trip threshold voltage. The device also includes compensation means for compensating for the trip threshold voltage of the modulators. These compensation means comprise at least one operational amplifier connected between the gate electrode and the source electrode of the modulator. The feedback of this operational amplifier compensates for the trip threshold voltage of at least one modulator whatever the value of the said voltage.
