|20130120353||Display Apparatus - There is a need for decreasing a variation in times for writing to TFT elements for pixels in a direction along the extension of a gate line in a liquid crystal display apparatus. A display apparatus includes a display panel having multiple gate lines and drain lines arranged in a matrix and a data driver for outputting a display data signal to each drain line. The data driver includes: an internal control signal generation circuit generating an internal control signal for setting a timing to output a data signal to a drain line of each block on a block basis by dividing the plurality of drain lines into multiple blocks; and a register circuit for recording a setting for division of the block, a setting for delay direction and width of a timing to output the data signal, and a setting for rising and falling of an internal control signal.||05-16-2013|
|20120287029||Display Device - A display device comprises a driver circuit having a shift register circuit having a level conversion function is provided with a simple circuit configuration of first, second, and third basic circuits connected in tandem at multistages. A common clear signal is supplied to a control electrode of a third transistor of each basic circuit, a first clock is supplied to a control electrode of a first transistor of each of the first and third basic circuits, a second clock different in phase from the first clock is supplied to a control electrode of a first transistor of the second basic circuit, outputs of the first and second basic circuit are respectively supplied to control electrodes of second transistors of the second and third basic circuits, and an inversion output of the third basic circuit is supplied to a control electrode of a fourth transistor of the first basic circuit.||11-15-2012|
