What is in-cell technology

In-Cell is a fundamentally new touchscreen technology. Its use allows to reduce the thickness of the gadget by 0.44 mm. Currently, touchscreens are manufactured using the widespread On-Cell technology, in which touch sensors are positioned above color filters by a single layer, or by Glass-On-Glass technology, in which the sensor sensors are located directly on the display surface.

In the new In-Cell technology, sensors will be embedded directly in color filters, located directly below the extreme layer of glass on the screen. Thus, the need to use a medium layer of glass is excluded. The combination of LCD display and touch layer is based on multiplex electrodes that are commonly used for touch input relays. In In-Cell technology, these very electrodes are used to process touch control signals and screen pixels. This allows not only to reduce the dimensions of the touchscreen display, but also its weight, as well as speed up the response of the sensors themselves to touch.

Sharp and Toshiba corporations have been selected as manufacturers of the new type of screens as having the technological capabilities to produce them. It was the Japanese who were the first to introduce touch elements on the market with a thin layer of film transistor inside rather than on the surface of a glass substrate of a liquid crystal screen. In addition, the result of this division of labor should also be a significant acceleration in Apple’s production rate. However, the Japanese are keen to keep up with Taiwanese companies, which in the near future plan to present their own developments based on the technology of In-Cell.

In case of successful introduction of In-Cell technology, it will be distributed to smartphones, tablets and ultrabooks around the world. However, analysts from rival companies doubt In-Cell’s technology will reach consumers in the near future. They draw their conclusions based on the lack of readiness of new technology for serial production.
