Driver for electroluminescent display, display comprising such a driver, and recorder comprising such a display |
摘要 |
<p>The present application discloses a driver for electroluminescent display having a configuration comprising: a drive transistor for supplying a current of the quantity corresponding to a gate potential, into an electroluminescent element as a driving current; a first switch installed in the path of the driving current passing between the element and the drive transistor, for controlling the flow of the driving current; a second switch for switching between the first state of setting the gate potential of the drive transistor and the second state of keeping the set gate potential; a circuit for supplying a signal for controlling the flow of the driving current in a restricted state to the first switch, for a predetermined period in a period after the starting the supply of the potential for driving the drive transistor from a power source and until start of driving the element in a normal operation; a circuit for supplying a signal for setting the second switch at the first state, to the second switch: and a circuit for interrupting a signal for setting the gate potential while the second switch is in the first state in the predetermined period.</p> |
