New Transflective Industrial Monitors from Pepperl+Fuchs Deliver Maximum Viewability, Even in Sunlight



TWINSBURG, OH - Pepperl+Fuchs introduces Transflective Flat Panel Monitors. The latest addition to the company's family of industrial LCD monitor solutions, these 15 in. transflective models are specifically designed to deliver the high viewability needed in applications with direct sunlight, as well as the robust operation demanded of harsh outdoor environments and/or continuous duty operations.

"As flat panel displays find their way into more and more outdoor process applications the need becomes far greater for them to be readable when exposed to sunlight, and most off-the-shelf displays are not properly equipped to handle the demands of such applications," says Kristen Barbour, Pepperl+Fuchs Product Manager.

A regular transmissive LCD has poor readability in outdoor environments, so many low cost flat panel manufactures' try to solve this problem by increasing the number or intensity of the backlight bulbs illuminating the LCD modules. This approach provides a certain level of sunlight readability; but there are also drawbacks such as extra power consumption, excessive heat generation, and the need for a larger then necessary housing to accommodate the extra bulbs. The excessive heat generated by the additional bulbs will also prematurely age the LCD components, causing a very short life span of the display.

A better solution is transflective LCD technology. Unlike a standard transmissive LCD where lights from the backlight pass through the LCD layer to combat ambient light, a transflective LCD reflects and transmit light, actually leveraging the ambient light to improve visibility across the widest range of ambient light conditions.

"When exposed to sunlight the transflective flat panel display functions mainly as a reflective display, where sunlight is reflected at the back of the display through an integrated partially reflective mirror layer, also know as a transflector layer. When it's dark or in low ambient light, the display functions as a transmissive backlight display. Using reflected light beams as its source of illumination increases viewability in direct sunlight, while enabling an affordable and efficient solution for outdoor LCD applications without the negative drawback of an exclusively transmissive solution," says Barbour.

Transmissive display vs. Transflective display - how it works.

Pepperl+Fuchs Industrial Flat Panel Monitors are a true industrialized monitor made of 100% industrial-grade components that deliver the highest MTBF in the industry at over 550,000 hours. These high quality monitors are available as general purpose displays or as a UL listed Class I/Div 2 device. They come in a variety of mounting styles to suit varying application needs, and can even be combined with a Pepperl+Fuchs Bebco EPS purge system for Class I/Div. 1 hazardous environment mounting. Touch screen options are available.

These flat panel monitors are rated for use in temperatures ranging from -10° C to 55° C. They accept standard VGA or NTSC inputs from a PC or video camera source. Additionally, they can multi-sync to any standard video mode from 640x480 to 1600x1200 at scan rates from 60 to 75 Hz, without image distortion or flicker. The DM5xx are 12 VDC powered displays, powered from an external power supply to keep heat away from the monitor, maximizing reliability and operating life.
