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).
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.
Planet Radio TV tune in on any device
Planet Radio TV plans to be Africa’s first online broadcaster that allows its listeners to watch via Internet and satellite TV as well as listen via FM or Internet radio. SEAN BACHER visits its studios.
Planet Radio TV (PRTV) is broadcast much like any other terrestrial radio station, allowing its users to tune into it with a standard FM tuner. But its owner, Planet Image Productions, is about to launch two other means of tuning into the station.
In the coming month, MultiChoice will place a new satellite in orbit that will, by the new year, allow Planet to broadcast to subscribers via the satellite. Planet has also announced the PRTV app, which can be downloaded to Apple, BlackBerry, Android and Windows Mobile devices, allowing users to stream the content to their phones and tablets.
‚”What makes this unique though is that our systems will automatically detect a user’s connection speed and stream content in a format that suits that speed, says Planet Image CEO Wale Akinlabi. ‚”For example, someone connecting through 3G will be able to view high-definition video and hear high-definition audio. A user with a slower connection will still be able to view and listen to the station, but at a lower quality.‚”
This, he believes, will eliminate the buffering issue which discourages many users from streaming video and audio to their devices.
The radio station comprises 80% African music, with the remainder being international, and is targeted at Africa’s youth.
‚”At PRTV we intend to change the way consumers view, listen and interact with television, radio and Internet mediums,‚” says Mabel Mabaso, chief operations officer and director at Planet Image. ‚”It is an exciting platform that synchronises three mediums, providing opportunities for consumers and advertisers alike.‚”
Planet RadioTV differentiates itself from other local broadcasters with its clever use of software and hardware. Planet Image uses a high-definition video-graphics (HDVG) rendering program, designed by Orad, an Israeli company specialising in TV production software. This software suite, combined with four Panasonic high-definition cameras, is able to detect and focus on a person’s voice. When the camera fixes on a voice, that camera is automatically activated and begins broadcasting. Should someone else begin talking, a separate camera will detect the voice and focus on that person.
The software controlling the cameras also performs basic video editing. Mabaso says that, although the initial cost of the equipment was more than that of standard cameras, it will prove well worth it, as it eliminates the need for a dedicated cameraman filming the show in the studio.
‚”Another payoff is that we don’t need that much office space,‚” she says.
Based in Randburg in Johannesburg, the studio is small in comparison to most others and the control room is just big enough for one person.
‚”The control room merely serves as a back-up should one of the cameras fail. It also allows us to control when and where visual adverts appear.‚”
The system is also tightly integrated with applications like Skype.
‚”We can interview someone overseas without having to send a crew there to perform recording. We simply communicate via Skype, making the interviewee’s Internet camera an extension of our own in-studio cameras.‚”
Besides featuring local and international music, the station has regular fashion, food and cooking, music and culture segments, which are broadcast to around 30 000 listeners around Africa.
Rounding up the technology aspect, PRTV has integrated Twitter and Facebook, allowing its listeners to interact with DJs.

Canon EOS M – small and simple
Canon has extended the EOS range with the EOS M, its first compact system camera. Although not yet available in South Africa, the EOS M offers DSLR quality images and full HD recording in a compact, easy to use device.
Canon has expanded the EOS range with the launch of the EOS M. The company’s first ever compact system camera (CSC), the EOS M offers DSLR-quality imaging and full HD movie creation in a compact and easy-to-use model.
The EOS M is available in sleek black, glossy white, stylish silver or bold red colours, and condenses Canon’s EOS imaging heritage into a stylish, compact design. The model launches alongside two new lenses, the EF-M 22mm f/2 STM pancake and the EF-M 18-55mm f/3.5-5.6 IS STM standard zoom, as well as a new compact EX Speedlite the Speedlite 90EX. For those who want to push their images even further, the EOS M can also use Canon’s range of EF lenses with the new Mount Adapter EF-EOS M, for even more creative freedom.
The quality of a Canon DSLR
The EOS M’s high-resolution, 18 megapixel APS-C hybrid CMOS sensor also allows you to blur the background for beautiful portraits, or for close-ups with impact.
With the inclusion of Canon’s DIGIC 5 processor, colours ‚’pop’ and skin tones are beautifully natural, while a super-fast shutter allows you to capture split-second action.
Shoot what you see and easily express your creative vision
Every aspect of the EOS M has been designed to make it simple to capture high-quality images. With the high-resolution, 7.7cm (3.0‚”), Clear View LCD II Touch screen, the EOS M gives you as much or as little control over your photos as desired. Simply select different shooting modes and settings via the on-screen icons, or let Scene Intelligent Auto adjust the camera settings according to the subject and shooting conditions, leaving you free to focus on composition and selecting the perfect moment to hit the shutter release button.
Turn film-maker with EOS Movie and Video Snapshot
When a moment calls for more than a still image, the EOS M lets you switch to Full HD video with stereo sound.
Extending the EOS System with dedicated accessories
In addition to compatibility with Canon’s existing EF lenses, accessories and Speedlites, the EOS M launches with its own range of accessories. Two new EF-M lenses offer portability and high performance when using the new model the EF-M 18-55mm f/3.5-5.6 IS STM standard zoom and the EF-M 22mm f/2 STM pancake lens. Both feature new stepper motor technology for exceptionally smooth AF performance, as well as precision Canon optics, while their compact designs offer the perfect form-factor to complement the camera’s pocket-sized body.
Additionally, the EOS M will ship with the new Speedlite 90EX flash unit as standard. Lightweight and highly-compact, it offers a maximum guide number of nine and supports wide-angle lenses, making it an ideal general-purpose flash for everyday use. A wireless master function also allows the control of multiple flash guns wirelessly, allowing more advanced users to experiment with a range of creative lighting effects.
