We are surrounded by various IoT solutions. Our experience shows that in some applications, we can refer to specific “standards”, e.g., in wearables, commonly used are OLED displays. In this article, we describe three exemplary IoT devices, indicating which display technologies ...

In this series of articles, we present the most popular interfaces used to data transfer, in this case – images, between devices providing data such as processors/controllers or computers and devices presenting data such as displays and monitors.

Today, smart buildings are not only homes or offices, in which we can regulate each room's parameters like lighting or temperature via control panels. More and more often, we can find smart solutions in public space – these are, e.g., interactive systems of navigation used by, e.g., claimants in government offices.

I'm sure that it happened to you many times. You are in a big building, like a hospital, university, or office, looking for that one room with number X. Finding your way from the entrance to your destination requires a lot of skill, asking around, and simply …getting lost.

What stands behind demanding applications? Generally speaking, we can say that these are various devices exposed to adverse factors. Among them, e.g., electromagnetic interferences, dusty or humid environments, prevailing weather conditions. They can impact the operation of the devices, even yielding damage to the module. What to do to prevent such situations?

How to fit the display brightness to the ambient brightness? Mainly it depends on the display technology - all in all, not every solution is a source of light, so not every solution is specified with the “brightness” parameter.

In one of the previous articles in Uni’s ABC series, we have discussed the crucial parameters of LCDs, pointing out, e.g., resolution, brightness, contrast ratio, or viewing angles, which impact the readability of the presented content. In some applications, there is also another worth noticing factor, that is, the LED’s durability.

USECs and USEMs are two display solutions based on E Ink's EPDs developed by the Unisystem's team. They can also be used by companies that do not have appropriate resources, both human and equipment.

The abbreviation OLED may be associated with TVs showcased in the electronics shops. We colloquially call them just “OLEDs.” This term derives from “organic light-emitting diode,” which is essential to provide OLED TVs (or broadly speaking – to OLED displays). This article presents OLED technology, one of the youngest display technologies available on the market.

We have always strived and still strive to be an important player on the market, so that is why we can not look to one's laurels – we continually improving Unisystem. Recently, due to the increasing number of orders, we have remade our cleanroom. Moreover, we also extend our offer by adding new services like, e.g., designing and producing non-standard solutions on customer's demand.

No doubt, the LCD-TFTs are still the most popular components to visualize the information used in various applications. Their universality is determined by, e.g., straightforward adjusting the LCD-TFTs to the project requirements – you can not only choose the optimal size but also customize the parameters of the display.
