The release or any announcement about the successor of Apple's iPad mini is not expected anywhere in the near future, however, rumors will keep coming.

According to a recent rumor, Apple has started working on the touch display panel of iPad mini 2 with Shenzhen Century Science & Technology (SCST), a subsidiary of Apple's leading supplier Foxconn.

SCST's Retina display panels are based on One Glass Solution (OGS), which are reportedly being tested by the Cupertino-based company.

According to a China Times report,  the OGS monolithic touch technology is more advanced that the display technology introduced in the iPhone 5. The iPhone 5 the in-cell display process which has lesser competitive advantages when compared to the OGS monolithic touch technology. The report also adds that Apple will upgrade the iPad mini 2's display resolution to 1,024x768 pixel to Retina whereas the size of the device will be 7.85 inches same as iPad mini.

 The report also says that SCST may collaborate with another Taiwan-based company, Innolux, and become the third panel supplier for iPad mini after LG Display and AU Optronics. Apart from coming with the 7.85 inch Retina display with OGS technology, iPad mini 2 will also feature new photomasks. If these developments are really taking place then it indicates that the production of the next generation iPad mini has already begun.

A forecast report from DisplaySearch suggests that the shipments of iPad mini and iPad mini 2 in 2013 will reach up to 50 million units, exceeding that of the 9.7-inch iPad.

Rumors have also surrounded the release date of the fifth generation iPad.

According to a report from Japanese site, Macotakar, the iPad 5 (fifth generation) might come in market by March this year. Though there is not official statement about the release date of the device so far, the site claims to be quoting 'inside sources.'

Earlier there were reports that Apple will change its product release cycle because of the increasing competition from Samsung and other companies. Going by the reports, it seems, the Cupertino-based company had done it as it released its last product in October 2012 only.
