In-Cell Touch Panels Prove To Be Troublesome for Apple

In Cell Touch PanelsApple is now facing an unexpected technical problem which is caused by low yield rates of the in-cell touch panels. Poor yield rates may result in low profitability for display manufacturers, which certainly disrupt Apple’s shipping schedule. Consequently, the company is offering a subsidy of between $10 and $15 per panel to encourage Sharp, LG Display and Japan Display produce more in-cell touch panels.

Japan Display, for example, could only deliver a yield rate of 50 percent. The combined shipment of all manufacturers only reaches less than 5 million units, far below the previous target of 25 millions. Approaching TPK, a panel supplier for the previous iPhone models may not be a workable solution for Apple, as it still employs the older full-lamination process. Reverting to an older touchscreen technology would only cause further delay to the launch schedule and cost the company more money.

Unlike current display technology, the in-cell panel allows integration between the touch-sensor and the LCD, resulting in a lighter and thinner device.
