The iPhone 5 introduced a bunch of both small and big advances in terms of display tech, most of them centered around the in-cell display process which laminates the cover glass to the display itself. As a result, in-cell tech reduces the iPhone 5′s thickness while increasing the image clarity by removing a third layer, which reduces light refraction noticeably. On the downside, this technology reduces the response speed of the touch panel.

This becomes especially evident when moving your finger across its screen in a rapid succession. Given the slow response speed of the iPhone 5′s touch panels caused by the in-cell technology, Apple reportedly is going to adopt the new Touch-On-Display technology from Chimei Innolux, a Foxconn subsidiary, to solve the problem…

The China Times reports that the Cupertino firm is already working with Chimei Innolux on the new Touch-On-Display panels that will be used on the next-generation iPhone, probably the forthcoming iPhone 5S which is expected around July.

Samples have been sent to Apple for testing in the hope of entering the iPhone maker’s supply chain. The report goes on to note that Innolux has converted its 4.5G line in Zhunan, Taiwan into a touch panel production line and plans on launching two new such plans.

The new display tech won’t make the display assembly any thicker, a source pointed out.

A report last week claimed Apple intends to refresh iOS devices this year with IGZO panels, reportedly turning to Innolux which has reportedly been licensed to use Sharp’s IGZO display tech on its 3G and 5G lines.

Here’s a quick backgrounder on how the in-cell tech the iPhone 5 uses differs from the ordinary touch screen technology that prior iPhones incorporated.
