Signal drive circuit, display device, electro-optical device, and signal drive method |
摘要 |
A signal drive circuit for an active matrix type liquid crystal panel. This signal drive circuit comprises: a shift register for shifting image data sequentially on a block basis, each block constituting a plurality of signal lines, to correspond to signal lines of a block; a line latch for latching the image data in synchronization with a horizontal synchronizing signal; a drive voltage generation circuit for generating drive voltages based on the image data; and a signal line drive circuit. This signal driver controls a partial display based on the partial display data which is designated on a block basis. Each of the signal lines in a block set as a display area is driven based on the image data. Each of the signal lines in a block set as a non-display area is driven by a predetermined non-display level voltage generated by a non-display level voltage supply circuit.
