Abstract
In an active matrix display apparatus including: pixels provided in a matrix pattern, the pixels each including a memory circuit which retains data while refreshing the data, a data signal electric potential which is supplied from a source line in a period t1 and written to a node which is connected to a liquid capacitor is higher than a data electric potential of the node, the data electric potential being obtained in a period t14 after a refresh operation of the memory circuit.
Claims8
An active matrix display apparatus comprising:
- pixels provided in a matrix pattern,
- the pixels each including a memory circuit which retains a data electric potential while refreshing the data electric potential, the data electric potential corresponding to data which has been supplied as a data signal electric potential and written to the memory circuit, and
- the data signal electric potential being different from the data electric potential which is generated by a refresh operation of the memory circuit and whose polarity is identical to a polarity displayed during the writing;
- wherein
- the data signal electric potential differs from the data electric potential by a difference between a feed-through voltage generated during writing of data and a feed-through voltage generated in accordance with the refresh operation during writing of video and by a voltage generated in accordance with a capacitor coupling occurring during the refresh operation.
