TFT display reliability and operating environment

TFT screens have dominated the visualization industry for a long time. TFT LCDs are widely used in our daily lives, including in communication equipment, household appliances, industrial automation goods, consumer and automotive applications, corporate settings, and healthcare. Although there are many LCD products on the market right now, not all of them are appropriate for all applications. For industrial LCD monitors, this is especially true. It's critical to comprehend your target market and any particular design challenges in order to choose the ideal LCD display for your application.

1. Reliable Products

The great majority of LCD screens are created for consumer electronics including gaming consoles, cameras, tablets, and smartphones. In contrast to industrial applications, they have extremely distinct requirements. Consumer display modules frequently lack the toughness, dependability, and cutting-edge characteristics needed to succeed in an industrial setting due to intense price competition and short production cycles.In consumer applications, product life cycles are often frequently substantially shorter. Screens made for these uses are often only accessible for one, at most, two years.

For industrial applications, however, display modules must have long product life cycles, frequently up to ten years or more. Additionally, a replacement product for an industrial module that a manufacturer discontinues should be backward-compatible in order to fit into the existing enclosure without necessitating a system redesign.

2. Operating Situation

When choosing displays for today's industrial applications, it's important to take into account their capacity to tolerate changes in temperature as well as shock and vibration. In addition to being able to tolerate a range of operating temperatures, they must be robust enough to withstand repeated bumps or jiggles from surrounding machinery and machine operators.

Wide operating temperatures

Industrial displays are frequently enclosed as a component of a bigger piece of machinery. In these circumstances, the heat produced by the equipment in the immediate area becomes trapped inside the enclosure, which may be harmful to many displays. Because of this, it's critical to consider the actual storage and operation temperature needs when selecting a display. The most effective way to assure compliance with the storage and operating temperature requirements is to choose a display that is optimized for these types of conditions. While steps can be made to dissipate the generated heat, such as employing fans inside the enclosure, this is not the most effective solution.The operational temperature ranges of LCDs can now range from -30 to 80°C thanks to advancements in liquid-crystal technologies.

EMI, mechanical damage, shock, and vibration

Devices for industrial use should, on average, be more durable than those for consumer use. In order to increase shock and vibration resistance, it is possible to reduce the number of pin and socket connectors and use chip-on-glass semiconductors. The mechanical resistance and EMI characteristics of the unit are also enhanced by using metal bezels instead of plastic cabinets. It is possible to prevent scuffs and blemishes on the user surface by adding chemically reinforced front glass.
