Abstract:
1. A display comprising: a data line for transmitting a data current; a scan line for applying a select signal; a first switch coupled to the data line and turned on in response to the select signal from the scan line in a first period such that the data current flows through the first switch; a transistor having a first electrode, a second electrode and a control electrode, and for providing a current corresponding to a voltage between the first electrode and the control electrode through the second electrode; at least one second switch for electrically coupling the second electrode of the transistor to the control electrode of the transistor in the first period and a second period before the first period; a first capacitor having a first electrode coupled to the first electrode of the transistor, and a second electrode electrically coupled to the control electrode of the transistor in the second period and a third period after the first period; a second capacitor electrically coupled between the second electrode of the first capacitor and the control electrode of the transistor, such that the first capacitor and the second capacitor are connected in series between the first electrode of the transistor and the control electrode of the transistor in the first period, the first and second capacitors being for storing a voltage corresponding to the data current flowing through the first switch in the first period; and an emitting element for emitting light in response to the current provided through the second electrode of the transistor in the third period.
