LG claims breakthrough on lightweight displays

LG Display's AIT panelKorean giant LG said it will start mass producing lightweight screens for notebook PCs, which also are thinner than previous panels.

The technology, called Advanced In-Cell Touch (AIT) uses a touch sensor inside the LCD panel itself, rather than as an add on on the top of a notebook display.

These type of panels are already in use in some smartphones, including the LG G4s but the company said it is the first time they will be produced for notebook PCs.

The panel’s thickness has been reduced by a millimetre and its weight by 200 grams, compared to ordinary 15.6 inch touch embedded panels with Full HD.

LG also claims that it will offer a brighter and clearer screen picture.

The company claims it has already signed contracts with a number of global notebook PC manufacturers in 14-inch and 15.6-inch sizes, but it declined to say which customers had signed on the dotted line.

LG said that in 2014 10 percent of notebook PCs were touch sensitive, a figure that is expected to rise to 20 percent in 2016 and 30 percent in 2019.

Amazon leans on Fire supply chain

Taiwanese OEM Quanta Computer is really ramping production for Amazon’s first full-on tablet, the Kindle Fire. 

Amazon, according to Digitimes’ sources in the supply chain, is telling its manufacturers to get their skates on.

It wants shipments to hit five million units as early as the end of December, or the beginning of January. Clearly Amazon is expecting the Fire to be a big hit.

Touch panel supplier Wintek has also pushed its forecast up and is estimated to be shipping up to 3.5 million of its panels to Amazon before the end of the year.

Others have been building up their component inventory at a careful pace.

Quanta, according to Digitimes has been taking the steady-steady approach in keeping shipments regular, just in case Amazon changes its mind about the orders.

600 million touch screens shipped last year

Displaysearch said that a total of 606 million touch screens shipped last year, a rise of 29 percent compared to the year before.

Of the type of screen, shipments of projected capacitive screens increased considerably – largely fuelled by Apple’s iPhone and iPod. The Apple iPad adopted this method of touch screen this year, and Displaysearch predicts that this type will beat passive resistive tech to become the market leader in 2010.

There are, said Displaysearch in its report, over a dozen different touch screen technologies and 90 companies are making resistive technology this year.

But for projected resisistive types, there are now 56 manufcturers, twice as many as in 2009.  Companies making the tech vary between those supplying only one type, while Elo Tyco Electronics and 3M produce several different types. While some firms make controller ICs, others make the entire modules.

Mobile phones soak up most of the market for touch screens, with 376 million of the 606 million used there last year – 25.6 percent of the total market.

This year, in cell touch screens are expected to show high growth – this type of technology is aimed at large sizes.

Poisoned Wintek workers OK now, firm claims

Optoelectronics company Wintek issued a statement intended to re-assure shareholders that its house is in order.

Last week we reported that one of its employees at its Chinese factory in Suzhou called for an investigation into the company’s practice.

Wintek had used the poison n-hexane to clean Apple components, including iPhone touch screens.

Wintek released a statement to the Taiwan bourse yesterday about the incident. It said that the incident using n-hexane in August 2009 was now resolved.

“At the time of the incident, Wintek immediately enacted a number of effective improvement measures that are still under implementation including the immediate removal of n-hexane from the production lines. All affected workers were then screened and medical treatment has been provided to all personnel who were affected by the exposure and they are now recuperating or have returned to their jobs,” the statement said.

Wintek further said that n-hexane is widely used for cleaning in the electronics industry and is not on the national list of highly toxic substances.

But, Wintek continued, “when persons come into contact with n-hexane for extended periods of time in poorly ventilated spaces, symptoms such as fatigue, numbness of the limbs and peripheral neuritis can appear. In severe cases, it can also lead to neuronal damage. However, if the affected people are given the proper treatment, they can successfully recover from n-hexane exposure. As a result, companies need to take effective occupational health protection measures when using n-hexane.”

It acknowledged that some employees at its wholly owned subsidiary United Win in Suzhou became ill at the beginning of August 2009.

“Our company made it our top priority to ensure that the affected personnel received well medical treatment and take corrective actions in internal management,” the statement said.

Those actions included stopping using n-hexane, giving employees with personal protective equipment, improving ventilation, and measuring airborne chemicals.

Wintek has carried out six inspections since August 5th 2009, and checked for n-hexane and that acetone and other chemicals were within occupational health standards.

It has ensured anyone affected by n-hexane were given prompt treatment. The affected employees have recovered or are in the process of recovering, Wintek claimed.
