Abstract:
An electroluminescence display apparatus for performing display operations by driving an electroluminescence device having an emissive layer between a pair of electrodes, the electroluminescence display apparatus comprising:a sampling circuit for sampling an analog video signal at a predetermined period, the sampling circuit is an analog switch having a p-channel transistor and an n-channel transistor; a capacitor for holding a sampling voltage proportional to the sampled analog video signal that is output from said sampling circuit; a first switch for switching, which is disposed between said sampling circuit and said capacitor and which turns on and off according to a selection signal, for supplying the sampling voltage from said sampling circuit to said capacitor; and a second switch for device driving, which is connected to said electroluminescence device, for the purpose of controlling the light emission at the device by supplying current to said electroluminescence device according to said sampling voltage held at said capacitor, wherein a positive voltage is applied to one end of said second switch and said capacitor.
