LCD Panels for industrial applications come in all forms and sizes. They include digital signage monitors, touch screen panels and panoramic outdoor displays. They are often put up for employees for day to day operations, as well as customers to marketing purposes.
No matter what the application, they are a significant investment for any company. Therefore, they must be bought carefully. Here are certain important considerations when purchasing industrial application LCDs:
The size of the LCD display makes a huge difference on the price. And several factors make a big difference on the size. The factors include:
- Availability of space
- Purpose of the Display
- Readability (distance from which the display should be visible)
The LCD display shouldn’t be too big or too small, but just the right size in order to be effective.
Resolution means the number of pixels that can be displayed in a monitor. Simply put, the greater the resolution of the LCD panel the better will be its display. However, this also means higher price.
Outdoor applications do not require very high resolution, but bigger size, while the opposite is true for indoor applications. So the choice should be made accordingly, which keeps the effectiveness as well as the cost in mind.
Pixel Response Rate
Pixel response rate is the amount of time that one single pixel takes to change its shade or color. This rate is measured in milliseconds. LCD panels that have lower pixel response rate often show white noise, or ghosting, and often look very ineffective.
This is why LCDs with high pixel response rate should be chosen or commercial reasons, especially for advertising. 2-5 milliseconds are usually considered to be the ideal rate.
There are certain important specifications to consider when purchasing an LCD panel. These include:
- Refresh rate
- Contrast ratio
- Viewing angle
- Sunlight readability
The refresh rate refers to the number of times the LCD can update its display in a single second, which is measured in Hertz.
Contrast ratio is the ratio of luminance of white compared to black. The higher the ratio is the better.
The viewing angle is the readability of the LCD display from different angles, while the sunlight readability refers to the ability of the LCD to be read in daylight.
There are usually two types of screen coatings that are applied to LCD panels, glossy and matte. Glossy coatings are used to display vibrant colors in low light conditions; however, they can reflective and glary in bright light.
