What \ OLED Television
price \ $7999
urved screen OLED television? So last September. A national retail chain is advertising LG’s 140-centimetre OLED television, the one with the gently curved screen, for $7999, but you can do better than that. An enthusiastic salesperson offered me $7848, today only. Hang on. This is the screen that was unveiled only last September amid glitz and bubbles for $11,999, and it has just plummeted four grand? You’d be a bit depressed if you’d bought one last month. What happened? I suspect it’s all about the Consumer Electronics Show held every January in Las Vegas, where electronics companies show off their new toys and give us an inkling of what’s to come. OLED televisions (it stands for organic light-emitting diode) were high on this year’s agenda. OLED has several special properties. It is technology that can be laid on a surface, in this case curved glass, without adding any appreciable thickness. Hence your OLED telly is only as thick as the glass that hosts it. This is pretty special when you see it for the first time – it’s just a sheet of glass but it’s also a television. Like plasma, there’s no backlighting, so blacks are truly black because, when black is called for, the pixel emits no light at all. Contrast ratios are therefore way better than backlit LCDs and LEDs, and on a par with plasmas. Small OLED screens have been around for decades (lots of up-market car audio screens are OLED) but it is still extremely difficult to manufacture in large sizes. Get up to 140 centimetres and the failure rate is high –

one independent source says 90 per cent. It suggests that when you pay for your 140-centimetre OLED, you’re also covering the cost of nine that failed. Even so, the industry views OLED as a powerful weapon that is getting us all into the shops to replace our perfectly good plasmas and LCDs with something newer. At the Las Vegas show, Samsung unveiled several, including one that’s bendable. TCL, one of the world’s biggest television manufacturers (it turns one out every 2¼ seconds, 24/7) announced the imminent release of a 140-centimetre OLED. And TCL is into ultra-sharp pricing. Maybe LG decided to put on its

running shoes and slash a third off the price of its offering. Or maybe, in these fast days, it’s now old tech. Whatever, it’s still a special screen. The technology is remarkable and the picture quality is sharp, deep and gorgeous, with each pixel carrying yellow as well as red, green and blue. The screen has no frame, although there is a narrow black border around the picture and the speakers are in a see-through panel. A good soundbar or speaker stand is still going to do a better job. Samsung also lists a 140-centimetre curved screen OLED on its website but I had no luck finding one. The woman in Doncaster couldn’t find it on the company’s inventory and suggested I ring Chadstone, but the guy there had never heard of it. \ firstname.lastname@example.org

ood has a profound impact on our health, wellbeing and disease risk. If we seek wholesomeness more often and add physical activity several times a week, our disease risk will decrease substantially.

Individuals with ongoing sleep disruptions and stress also tend to consume less fibre and skip breakfast. Talk to your loved ones or seek professional help if you have sleep issues or your anxiety levels have peaked.
Poor sleep patterns and too little good-quality deep sleep are catastrophic. Deep sleep, stage four in the sleep cycle, is when bodies cleanse and repair. The liver functions in overdrive to “purify” the body and prepare us for the next day. This stage is essential for our body’s relaxation and coping mechanisms. Insufficient time in this sleep stage is associated with hormone imbalances that result in night-time alertness and daytime fatigue, irritability and anxiety. The sleep-deprived have a tendency to seek stimulants such as caffeine and processed sugars. Aim for seven to eight hours of quality sleep a night. Stress beyond our individual thresholds changes body chemistry. Due to the changes in hormone production and transport – and brain signalling messages – there is a disruption to digestion. It is extraordinarily taxing on the body and mind to process high levels of stress. As such, the body withdraws resources typically allocated to digestion and absorption of food and nutrients to modulate the adverse effects of stress. In doing so, nutrients are not
