LG launches new colour tech

Published

on

LG promises to take the TV viewing experience to a new level with RGBW technology, which adds a white element to the usual red, green and blue components of each pixel.

LG this week unveiled its new TV panel colour technology, M+, in South Africa.

M+, or RGBW, technology adds white colour subpixels to the colour filter of a conventional RGB LCD panel to create an image. The RGB three-color panel system has been a dominating panel technology since colour CRT-based televisions first hit the market, so M+ technology is a big leap forward in display technology.

A conventional RGB panel already has red, green and blue pixels. The M+ technology is not that much different to the RGB panel except for one big change. Instead of using the three static colours, RGBW implements four different combinations (RGB, WRG, BWR and GBW) that are constantly being circulated. The RGBW panel is made up of 2,880X4[RGBW] X2, 160 subpixels, which is the same as that of a conventional 4K RGB panel (3,840×3[RGB] ×2,160).

Why RGBW?

TVs using the RGBW technology have an enhanced brightness and energy efficiency, while costing less. A conventional RGB panel has a smaller aperture ratio because it has only coloured pixels. RGBW technology on the other hand has the extra white pixels, which means it provides more brightness. LG’s RGBW-enabled UHD TVs are capable of emitting up to 50 percent more light than a conventional RGB display and can be up to 37 percent more efficient.

The new RGBW technology meets three key elements of the 4K standard: resolution, colour expression and 4K upscaling. It will even provide the same picture quality than that of a RGB 4K when upscaling full HD content to 4K resolutions. With RGBW technology you’ll still be able to achieve UHD resolution without any loss of picture. This is because of its algorithm, where each pixel shares the nearest pixel’s subpixel.

LG’s RGBW technology meets the requirements of the Display Measurement Standard’s (IDMS) definition of 4K resolution, based on the 4K resolution standard set by the International Organization for Standardization (ISO) and also adopted by The International Committee for Display Metrology (ICDM) and THX Limited (THX).

The RGBW pixel configuration is more cost efficient than an equally sized RGB-based backlit display panel. That’s because a conventional RGB UHD panel needs more LEDs to emit an adequate amount of light, which ends up costing more to produce. By saving on production costs, UHD TVs are now much more affordable in both the short term and the long term. The new pixel structure shows how RGBW can offer a brighter image, yet still save energy.

5 things you should ask about buying a new TV

With so many technological advancements that cater to various needs, and endless options on the market, buying a new TV for your home can be pretty daunting. JACQUES BENTLEY, Southern African Sales Manager at Skyworth, offers a few tips when buying a new TV.

Given the role a TV occupies in the home – providing entertainment, relaxation and a window to the world for the whole family – it’s not a purchasing decision to be made lightly. Not to mention the fact that you’re likely to spend a rather large sum of hard-earned dough in the process. Fear not – we’re here to help you decide. Here are five important things to think about before you swipe that plastic to ensure your new TV will bring nothing but joy into your home (ok, and maybe a couple of disagreements on what to watch).

  1. Size matters

If you’re a fan of action-packed movies or nail-biting sporting events, you already know how important the size of the screen is. Consider the space into which your new TV will fit, and take measurements of the wall area or cabinet it’s going to sit on to make sure that you’re being practical about its size. How many people will be watching the TV at the same time? Now opt for the largest screen size that will fit comfortably in your lounge (and your budget). Generally, anything between 55 and 65 inches is a great all-round pick according to price, performance and how close most families sit to the TV.

  1. Is it digital-ready?

South Africa’s digital migration is upon us and by June 2019, you’ll either need a digital-ready TV that can transmit digital signals or a Set-Top Box to decode digital signals for your old, box-style analogue TV set. The benefits of investing in a digital TV include crystal-clear image quality, excellent sound and a wider range of channels. Ask the sales assistant to show you their range of digital ready TVs when making your selection.

  1. Does it have a 4K screen resolution?

Resolution refers to the sharpness of the TV picture, usually in terms of horizontal lines of pixels. Ultra HD/ 4K sets have four times more pixels than current Full HD screens. That’s as many as 2 160 horizontal lines, or 3 840 x 2 160 pixels. The result? Super-sharp, detailed and lifelike images, even on large screen sizes. For this reason, a 4K resolution is becoming increasingly popular because it’s a much better choice if you want to future-proof your investment – Skyworth’s G6 model was created with this in mind; it’s basically an Android TV made for the future.

  1. What will you be using your TV for?

Apart from the obvious activity of chilling out to watch your favourite shows, what else do you want to be able to do with your TV? Will your kids be using it to play games? Will you be streaming shows on it? All of these preferences will impact the specific features that will attract you to buy a certain model over another one, so it’s wise to do your research, either online or in store, before you say ‘yes’ to the device. Also, look out for at least four HDMI ports at the back of the set as these tend to get used up very quickly, especially if you are using accessories like a sound bar.

  1. Does it include cutting-edge technology?

From Google Voice Assist, allowing you to speak to your TV, to rich connectivity via Bluetooth, selecting a TV that has advanced capabilities makes for a smarter TV and one you aren’t likely to need to replace in a few years’ time. With Android System 6.0, an easily updatable operating system, the G6 TV is your best bet when it comes to constantly upgrading your TV without forking out money every time.

Kia makes car audio personal

KIA Motors has revealed its Separated Sound Zone (SSZ) technology that allows each passenger of a vehicle to experience an audio stream tailored to their individual needs.

Published

on

SSZ technology creates and controls the acoustic fields of the car, allowing the driver and each passenger to hear isolated sounds. The many speakers installed in the vehicle feature technology that uses scientific principles to reduce or increase audio levels of sound waves. This negates the overlap of sounds being heard in each seat, creating the same effect as current noise cancellation systems, but without the need for headphones.

“Customers in the autonomous navigation era will demand increasingly customisable entertainment options within their vehicles, which includes technological innovations such as the Separated Sound System.” says Kang-duck Ih, Research Fellow at KIA’s NVH Research Lab. “I hope by providing drivers and passengers with tailored, independent audio spaces, they will experience a more comfortable and entertaining transportation environment.”

People’s musical tastes vary, so some passengers choose to use headphones during a journey to isolate their audio stream, but this also creates an unnecessary social barrier when interacting with other passengers. When travelling in a vehicle equipped with next-generation SSZ technology, each passenger can connect their smartphone via Bluetooth and listen to their own music without interference from, or interfering with other passenger’s audio streams.

When the SSZ is utilised, hands-free phone calls can also be isolated to individual passengers, ensuring privacy when having important phone conversations on the move.

Furthermore, this ground-breaking technology can eliminate unnecessary sounds for the passenger, but provide them for the driver. Navigation sounds, or various alerts, allow the driver to focus on controlling the vehicle, while the SSZ system isolates these sounds, maintaining a quiet area for the other passengers. This has a particularly strong application for drivers with a sleeping child in the vehicle.

SSZ technology has been in development since 2014, and the completed mass production system is expected to be ready for installation in vehicles within one to two years.
