DynaScan tots up 10 with ‘world’s brightest’ display
DynaScan touts its new 84in large-format LCD display as the ‘world’s brightest’. Shown off for the first time at ISE 2014, the new product brings the company’s display portfolio up to 10.
The DS841LR4, as it is called, measures 84in diagonally. It incorporates a 4K Ultra HD 84in IPS LCD with an ultra-high brightness LED backlight, which culminates in a sunlight viewable 2,500-nit image.
This makes the solution suitable for large-scale display applications in high ambient light environments – for example in storefront windows, outdoor kiosks and other locations with direct sunlight. It’s targeted at customers who no longer want to use static posters or low-resolution LCD panels. To combat issues arising with solar heat gain – which could be a problem because the panel is located behind glass – the system includes
an ultra-quiet, high- efficiency cooling system, and a high-temperature resistant panel that can handle temperatures up to 110ºC (240ºF) before the device experiences any blackening defect. The LED backlight incorporates local dimming so that darker areas of an image receive less backlighting than lighter areas, producing a high- contrast image with deep black levels.
The solution also utilises
IPS display technology, which the company says produces accurate colour from all viewing angles. Moreover, each screen is individually colour calibrated to the D65 colour standard to ensure quality and uniformity when using multiple displays, although this can be customised to a required specification. The device is available
from this quarter.

{} Sharp’s virtually seamless videowalls
The 60in PN-602 LCD monitor from Sharp is part of the company’s Multi Display slim bezel range – which also incorporates the PN-V601 and PN-V600. Ultra-thin bezels along with what the company describes as exceptional image quality make the screen highly configurable for creating high-impact videowalls and digital signage applications. To ease this process the system offers easy assembly and control via the RS-232C interface or a network.
The monitor incorporates Sharp’s LCD technology, which enables highly
efficient use of light from the backlight and prevents light leakage. This, according to the company, results in outstanding image reproduction. With high brightness of 1,500cd/sqm, the system is suitable for indoor locations but also areas that are awash with sunlight. Sharp specifically points towards indoor sports facilities, transportation hubs, shopping centres and event venues as areas that would benefit most from the display. The product integrates Sharp’s local dimming technology to provide enhanced contrast

additional space, time and budget that would otherwise be required for external units. Secondly, an embedded Quad Image Splitter enables a single screen to split into four for the display of different sources. Thirdly, VTRON’s unlimited signal looping offers intelligent signal
compensation: the input signal is converted to DVI-D format, and looped out to the next LCD, decreasing the chance of signal degradation. Rounding off the signal

compared to conventional LCD monitors. An LED backlight adds to the image quality by ensuring uniform brightness across the entire panel. As well as excellent
image quality, the LCD monitor is said to have extremely low power consumption and long screen life, making it ideal for demanding 24/7 usage. These features, according to Sharp, will also decrease the load on heating, ventilation and air conditioning systems, translating into lower running costs and savings for businesses.
