A smartphone’s touch sensor layer, also known as the digitizer, is typically a separate layer from the LCD panel, adding more bulk to the device. Other technology options such as Samsung’s Super AMOLED display have tried to slim down by integrating the touch sensor into the glass itself.
Larger Screen?
Larger screen sizes are quickly becoming the norm for smartphones. Samsung took this to an extreme with its 5-inch Galaxy Note device, but 4.3-inch devices are becoming more common. Among PCWorld’s Top 10 smartphones, only the T-Mobile My Touch 4G Slide and the iPhone 4S have sub-4-inch screens. The iPhone has always had a 3.5-inch display.
Beyond getting thinner and perhaps bigger, in-cell displays provide better resolution over standard LCD displays, according to the Journal.
