IPS (In-Plane Switching) lcd is still a type of TFT LCD, IPS TFT is also called SFT LCD (supper fine tft ),different to regular tft in TN (Twisted Nematic) mode, theIPS LCD liquid crystal elements inside the tft lcd cell, they are arrayed in plane inside the lcd cell when power off, so the light can not transmit it via theIPS lcdwhen power off, When power on, the liquid crystal elements inside the IPS tft would switch in a small angle, then the light would go through the IPS lcd display, then the display on since light go through the IPS display, the switching angle is related to the input power, the switch angle is related to the input power value of IPS LCD, the more switch angle, the more light would transmit the IPS LCD, we call it negative display mode.

The regular tft lcd, it is a-si TN (Twisted Nematic) tft lcd, its liquid crystal elements are arrayed in vertical type, the light could transmit the regularTFT LCDwhen power off. When power on, the liquid crystal twist in some angle, then it block the light transmit the tft lcd, then make the display elements display on by this way, the liquid crystal twist angle is also related to the input power, the more twist angle, the more light would be blocked by the tft lcd, it is tft lcd working mode.

A TFT lcd display is vivid and colorful than a common monochrome lcd display. TFT refreshes more quickly response than a monochrome LCD display and shows motion more smoothly. TFT displays use more electricity in driving than monochrome LCD screens, so they not only cost more in the first place, but they are also more expensive to drive tft lcd screen.The two most common types of TFT LCDs are IPS and TN displays.

Today, more and more applications are using the display. Whether as a means to display the desired information or as an interactive element (HMI- human-machine interface) with a touch panel.

1. Display demands on the performance of the host processor and application developmentClassic character displays with some of the standard controllers are the least demanding because the required content is displayed only on the basis of the codes sent - we do not care about the content of individual pixels. This also implies that the development of character display applications is the least difficult.

Monochrome graphical displaysare considerably more demanding on the host processor, but thanks to the integrated controller the control is relatively easy and modern controllers (together with the firmware from the manufacturer) make it possible to simplify application development significantly.

Previous statements about the demands on the host (master) controller as well as on the development/complexity of the application apply only to standard displays without added intelligence.

However, there are already a variety of display module families on the market that incorporate a powerful graphics processor and firmware, which along with the development software (that is almost always available for free) can significantly simplify the development of graphics applications. The performance of the used processors is in many cases also sufficient to control the surrounding components, so that the entire application can be built on the basis of the display module, without the need for an additional microcontroller.

Almost every display can now be fitted with a touch panel - resistive or capacitive. Even OLED industrial displays are already becoming available with touch panels.

Although the ease of control and perhaps the habit from smartphones tempts us to use a capacitive display, it is not optimal everywhere. The ability to operate the resistive panel even with normal gloves is still a big advantage. Still, the touch panel slightly worsens the contrast and brightness of the display, so if the brightness of the display is a priority, it is better to use the display without the touch panel.

The LCD display can be with or without backlight. The vast majority of available displays now have a backlight, allowing the display to be readable in darkness or dark environments.

However, under strong ambient light, and particularly in direct sunlight, the backlight is usually relatively dim, and the readability of the displays in the sun is significantly impaired. However, there are also exceptions where it is possible to maintain fair readability of the displays even in direct sunlight thanks to the technology used and the relatively powerful backlight.

OLED displays also suffer from significantly reduced contrast in direct sunlight, but some types provide acceptable readability even under such conditions.

It can be stated that there are several display technologies on the market, but the absolute majority of display types use some analogue of LCD (STN, FSTN, TFT, IPS ..) or OLED. Some advanced technologies - such as VFDs (vacuum fluorescent display) are still available but are only beneficial for some specific cases, like operation in frosts with low power consumption at the same time.

So, knowing that even a modern IPS TFT panel is still a liquid-crystal display in its essence, it implies one fundamental fact - its reaction times and usually the contrast and viewing angles have a significant effect on temperature changes. However, even in LCD technology, we can find types capable of working in the range of -30 ... + 85°C, but it should be taken in mind that the characteristics of the display at the limit temperatures will no longer be optimal.

When selecting a display, it is therefore important to consider the temperatures at which the display will work, and in addition to allowing the extraordinary temperature conditions that may occur in the application environment. To learn more about the effect of temperature on display life, see our article Check the limits of your display.

Although it may seem that OLED technology is a winner, let"s take a look at the current market situation for OLED displays suitable for industrial applications:

The price of OLED display is about 1.5-4x higher than the LCD alternative.Types available for industrial applications are almost exclusivelyPMOLED(passive matrix)OLED alternatives are already available for many classic character displays(2x16, 4x20, etc.), with characters of the same size and identical or very similar mechanical dimensions and pin layoutIn the vast majority of cases, only monochromatic OLEDs are available. Full-colour RGB versions are available only in small sizes - approx. 1.4 "-1.7".Larger sizes of RGB OLEDs (as we know them from today"s smartphones) are available only exceptionally and usually have a very short availability, so they are not suitable for devices manufactured for many yearsThe best readability and lifetime(electric) have yellow OLED; white colour is also quite good. This is also reflected in the market offer where green, blue and red are available on a significantly smaller scalePower consumption of a fully lit (all pixels) OLED display may be comparable or even higher than that of an LCD with backlight, but in practice, the entire display is rarely used, and so the OLED alternative consumption is usually lowerThe contrast and viewing angles are of course excellent, as we have already described in several of our articlesReadabilityof OLED in the sun is noticeably deteriorating and, although relatively acceptable, specialized LCDs (particularly transflective) can achieve better contrast in direct sunlight

The display market and manufacturers" offerings are evolving very quickly, but we can supply any display upon request, either in sample quantities or in mass quantities. Therefore, if you have not found a display suitable for your application in our range, do not hesitate to contact us.
