20120162163 | DATA-HOLDING CIRCUIT AND SUBSTRATE FOR A DISPLAY DEVICE - A display device has a data-holding circuit with a capacitance and a display portion with a plurality of pixel electrodes, formed on a first carrier substrate. In the display device, a second carrier substrate disposed opposite the first carrier substrate is placed above the display portion, but the opposing substrate is not present above the area in which the data-holding circuit is disposed. The parasitic capacitance of the data-holding circuit can thereby be reduced. Therefore, the capacitance in the data-holding circuit can be reduced and the area required can be reduced as well. The display data of all the pixels is sent serially to the liquid crystal module without high-speed transfer for each frame time interval, and size can be reduced because the controller IC and interface circuit are formed on the same substrate as the display device substrate. | 06-28-2012 |
