In the meantime, QXGA
panels that has higher resolution with pixel density of over 260 ppi (pixel per inch) will increasingly replace XGA models as the mainstream application of iPad's display panels in the short term.
Analog Devices' 32 X 32 analog crosspoint switches for high-resolution video applications achieve a bandwidth of more than 500 MHz, allowing them to achieve the high speeds required to route QXGA
video signals without degrading image quality.
With panel makers developing ultra-high resolutions, such as 4K-2K for TVs and QXGA
(2048-1536 pixels) for tablet PCs, the average pixel density of FPDs is expected to grow over the next few years, said DisplaySearch.
Although the Cupertino-based company has not said anything in certain, it is expected that the new QXGA
displays will arrive with the 9.7-inch size of previous iPad models and will have a 2048 x 1536 pixels-per-inch (PPI) for HD playback.
It is undesirable to operate at the peak drive capability of an output stage, so use a wideband amplifier that has 60 mA to 70 mA of drive capability and a bandwidth that is roughly 30 MHz for composite video, 100 MHz for HDTV component video and up to 1 GHz for the various display resolution standards (Example: QXGA
2048X1800 requires 1 GHz).
has announced the availability of color and monochrome models of the company's 21.3" QXGA
Thin-Film Transistor (TFT) Liquid Crystal Displays (LCD).
