Over the years, Apple has been a consistent, top-caliber, smart technology manufacturer, with its standards remaining high. And with its promise of the latest installment of the iPhone, suppliers could be possibly running to-and-fro to meet tough demands of the tech giant as launching draws near. September 9 has been the marked date, but delay issues and technical manufacturing revisions are talks of the town.

According to reports, the iPhone 6's screen needs redesigning. Reuters notes that a source said that such redesigning "disrupted panel production". The site enumerated the suppliers asked to create the iPhone 6 screen: Japan Display Inc (6740.T), Sharp Corp (6753.T) and South Korea's LG Display Co Ltd (034220.KS). Yet these three companies remain silent.

Should things not fall into place, iPhone 6 can face a launching delay or a limitation of its initial stocks. Reuters' sources have also noted that stocks for the larger-screen iPhone are being readied by Apple for the year-end shopping season.

So what exactly is the problem?

According to two supply chain sources, the backlight which illuminates the screen had to be redone, pausing assembly for both June and July. As Apple aims to produce the thinnest phone possible, another source says that it wanted changes such as cutting back to a single layer of backlight film instead of two for the 4.7-inch screen.

"But the new configuration was not bright enough and the backlight was sent back to the drawing board to fit in the extra layer, costing precious time and temporarily idling some screen assembly operations," the source tells.

As Apple fans await more news about the possible launch delay, many could already be drooling over the unveiling of the most-awaited iPhone. According to reports, the phone will have both 4.7 inch (11.94 cm) and 5.5 inch (13.97 cm) screens -- definitely bigger than the 4-inch screen on the iPhone 5s and 5c. A sapphire displays, metal chassis, and a 13 megapixel camera are also packed in the phone, reports Forbes
