You know that industrial touch screen displays have a high cost performance. Currently, among the vast array of LCD products with varying manufacturing processes, many touch displays are designed and manufactured specifically for consumers, including laptop, desktop and low-end desktop monitors.
However, due to highly competitive pricing and real-time market factors, common modules do not meet the sustainability, reliability and advanced features of their industrial environment. Product life cycles in consumer applications are typically very short. As a result, displays designed and manufactured for these purposes typically last only 1 to 2 years. In recent years, LCDs have replaced CRTs in industrial display applications, including industrial automation systems and test and measurement equipment. Compared to CRT displays, LCDs are more convenient for the industrial market, especially for the selection of important criteria such as space, readability, and durability.
Space constraints and space issues are important factors that designers in industry should consider. Industrial LCDs are more flexible and thinner than CRTs, making it easier to find the right location for industrial equipment. On the other hand, CRTs have a large mounting area for accessories and also have accessories that need to be installed in specific places in the factory. In addition, LCD units are designed to be highly portable, so they can flexibly support the manufacture of expensive equipment under the same conditions as before.
The readability of touch displays is another highlight of LCD screens. It is important that touch displays in industrial applications need to support clear and accurate visuals in bright light environments in many ways. Almost all industrial environments are environments surrounded by bright light, challenging the readability of the display. The brighter the environment, the more difficult the transmission of the LCD screen. Because the standard readable brightness for people is 250 to 300 cd. Are some LCD manufacturers planning to extend the range beyond 450 cd? However, these require more energy, which also suggests that it is not the best solution.
One solution for improving the readability of touch displays in bright environments is to increase the contrast without increasing power consumption. In non-industrial environments, typical contrast ratios range from 200:1 to 300:1, so the machine operator cannot view the touch screen from a distance. Contrast ratios of 450:1 above and below are suitable for industrial environments. To increase contrast, one must get close to the contrast to distinguish between light and dark images.
Multi-view readability is another selection factor. In a typical industrial environment, operators want to view the display at an oblique angle rather than a positive angle. Therefore, it is important that there is little distortion or color change in the image when viewing it from different angles. In particular, display settings in consumer applications do not end up working smoothly because the image is lost or does not look tilted.
