Here is some information regarding the different touchscreen technology currently used in smartphones, their pros/cons and some examples of which phones use which.
Add on touch type The touch panel is separate from both the cover glass and the display panel.
In the past, this is what all phones used, ranging from budget to highend such as the iphone 4s. There was several variations, mainly whether an airgap was used, and if the material of the touch was film or glass. Those without an airgap and a glass sensor would give a very solid feeling screen, such as the iphone 4s. it's very durable but thicker and heavier than the other technologies.
Touch integrated into cover glass, also known as OGS or one glass solution. The touch sensors are integrated into the cover glass.
Many phones which you consider to use OGS don't actually use it. The huge disadvantage with this technology is that the touch sensor can be easily damaged and cracking the cover glass will always damage it. Depending on where the crack is, you may only loose only a small percent of the touch, half, or complete.
The 2 major smartphone makers who still use this technology in their flagship smartphones are Sony and Xiaomi. It has been previously used in Nexus phones, Oneplus One, LG G series amongst others. It's a good way of being able to include high quality displays which are thin and light, whilst keeping costs low. They are usually purchased as completed assemblies from screen manufacturers. Anyone notice how often you see complaints of touch screen problems with the Xperia Z phones? Unless you are okay with your phone becoming unusable if you crack it, do not buy a phone with this type of touchscreen.
Touch integrated into display, on cell and in cell.
These technologies have all the benefits of OGS whilst also being significantly more durable. Examples of phones which use this technology are recent flagships from Apple, Samsung, Huawei, LG, Asus. The screens with built in touch are usually purchased without a cover glass, then the glass of choice is applied ontop during assembly. Some cheaper phones also have this type of touchscreen, but with a lower quality display.
