Production of in-cell touch screens hinders the new iPhone

Apple the next generation iPhone might have to deal with the in-cell touch screen technology shortage. Reports are not always reliable with the website Digitimes. For manufacturers like the Japan Display, LG and Sharp to induce higher production numbers, Apple would be willing to spend $10 to $15 extra per screen panel. Low production numbers, the assembly of the new iPhone is in the way, so there are not enough copies that can be delivered.

Japan Display provides the most screens and the best yield rate (the percentage of parts that meet the quality requirements and can be used in products), but even with this company, there is only 50% usable. The screens are quite difficult to produce.

Due to the poor yield rates, combined shipments of in-cell panels for the upcoming iPhone are estimated at only 4-5 million units in July – far below Apple's target of 20-25 million for all of the third quarter, the rumors pointed out. However, Apple is still encouraging the panel suppliers to make more at any cost, and is even providing support including subsidies to help lower their production costs.

The low production numbers could ensure that Apple in July but 4-5000000 screen panels available for the production, while Apple was planning to have between 20 and 25 million iPhones produces in the third quarter of 2012, says DigiTimes.

The figure above shows how an in-cell touch screen is built: the touch sensors to process the LCD glass may be made much thinner. Apple has not yet announced the in-cell technology will be applied in future iPhones but several rumors suggest it. Possibly Apple can still move to TPK, manufacturer of previous iPhone models. But that does mean that traditional touch panels should be used. Digitimes was the first in April 2012 that spoke about the use of in-cell touch panels in the next iPhone. Later joined The Wall Street Journal join the rumors. As a Proof, Apple will use the new display technology found in Wintek manufacturer , where traditional displays can be made. That ran in June, a remarkably low turnover and Topeka Capital analyst Brian White h
