Impact Of Open Frame Displays On The Industries
When was the last time you saw a device of significant use and meaning that did not have a display
? Open Frame Monitors and other LCD displays are experiencing a rapid growth in demand since most commercial and consumer devices need a display that can show much more than mere black and white digits. Open Frame LCD displays are indispensable when it comes to bridging the gap between man and machine.
The key to a successful deployment of your devices is to plan ahead when choosing an Open Frame Monitor as your display. Although open frame displays primarily use off the shelf LCDs, the solution that you require may not necessarily fit the requirements of your specific project, whether that may be LCD size, viewing angles, brightness, contrast ratios, environmental and power requirements. In this article, we will try to give you some practical tips about choosing the appropriate Open Frame Monitor for you devices.
Ensure early planning: Make sure you design your open frame LCD during the earlier portion of the project lifecycle.
Know your audience: ascertain concrete details about the expected end-users and the environment they will use the device in. Based on this earlier planning, you might have to look for a Sunlight Readable LCD displays or High Brightness LCD. You will also need a rough estimate of the size of you audience and their viewing distance and angles. You may also need to use industrial Open Frame LCDs for commercial and industrial settings, where the LCD will surely be subject to constant wear and tear.
Open Frame LCD mounting: you will need to determine how the LCD is to be embedded or attached to the device so as to determine an appropriate bezel type, and mounting hole locations.
Widescreen (16:9) or Standard (4:3): The Aspect Ratio depends more on the type of content to be displayed and whether it will be displayed in the portrait mode or the landscape mode.
Color and Contrast: Despite popular belief, a higher color range does not necessarily add to better viewing in terms of the required use of the Open Frame LCD. Not all devices need a 16 million color LCD.Some devices merely require a higher contrast ratio or even a monochrome display. This depends on the demands of your particular application. Medical open frame displays may require only a monochrome display, while a digital signage application may require a higher amount of colors for vivid advertisements.
Interface: Most consumers require an Open Frame display that is more than a just a screen for presenting content or information. The recent increase in the use of touchscreen open frame monitors indicates that end-users are happier when they are able to manipulate the display screen. Touchscreens come in a variety of technologies including resistive, capacitive and SAW (Surface Acoustic Wave). They interface commonly via USB, as well as RS232 with the host PC.
Power: Ignoring this consideration might render your device completely inoperable. Portable devices have limited power sources and must not be fitted with high wattage Open Frame Monitors. For devices that will run on an open source of electricity, you must ensure you use a power supply that takes account of the power that the Open Frame Monitor needs to operate. Transflective displays usually require less energy than transmissive LCDs, but may not have a picture that is as brilliant in low light conditions. A cooling device may also need to be used especially if the LCD is to be used as an outdoor public display and is sunlight readable through the use of CCFL backlights. In-vehicle LCD displays are more susceptible to high environmental temperatures so a wide-temperature range LCD panel is recommended.
Mounting: this depends on the size and positioning of the Open Frame Monitor, as a slim open frame LCD monitor display will usually allow for more flexibility in mounting. It is essential to check the mounting hole locations of the display via the datasheets before consider a purchase.The amount of vibrations that the Open Frame Monitor will be subject to is also an important factor. Depending on the mounting location, IEC and MIL Vibration and Shock standard complaint mountings may be required for the application.
Vandalism: Does the Open Frame Monitor face the risk of being vandalized and de-faced? This is an important consideration if the LCD Display is to be installed in a public area. It is vital to use a 3mm (minimum) thick cover glass to protect the LCD panel investment. Various glass types should be compared to suit the application and budget.
Dust: If the operating environment has a common occurrence of dust particles, it is critical to make sure that the open frame LCD monitor is properly sealed between the LCD, the touchscreen and the bezel.
Optical Bonding: If available, optical bonding any additional surface over the LCD panel, including touchscreens, is highly recommended for best viewing performance.
Reliability: Consider the long-lasting application potential of the industrial open frame monitors. Given the continued change in technology and such requirements, you might not need an Open Frame LCD that can go on for 100,000 hours. Configuration management is an important consideration especially if youre using AMLCD displays that are likely to have smaller technology lifecycles.
Disposal: Considering the increase in environmental awareness, it may be an appropriate social policy to use a green or recyclable Open Frame LCD display when possible.
An open monitor LCD display is a crucial link between the device and its user. To not take into account all electrical, mechanical and environmental factors may render the display inoperable. Attention should be paid to these considerations before ordering your next Open Frame Monitor.
