Developing Led Technology

24 Eylül, 2021

Today, the highest resolution that technology giant companies have reached for home televisions is 8K, technologies such as OLED and QLED developed by companies to improve image quality are based on trying to maintain the black level of the screen while maximizing the brightness.

What It Means to Keep Black Background
Simple type LCD panels use fluorescent or LED as light source. The LCD panel creates the picture image from pixels, each of which can give a different color, the lighting unit does not have a very flexible structure in the background, the continuous light source can prevent many colors used in the image design from appearing in the desired tone. cannot be obtained as a result of its absence.

We can see OLED and QLED technology in home televisions these days, the target in OLED technology is that each led diode emits its own light, that is, the light source is the RGB led diode itself, this allows to get really deep black when the RGB led diodes are not lit, so in terms of NITS according to the quality of the LED diode. the brightness level and color quality will be higher. A similar logic is used in QLED technology, thanks to the many LED diodes placed behind the classical LCD panel, the illumination of RGB pixels is done from many points, and a high level of color quality is achieved by maximizing the black level.

Industrial Led Display

Industrial LED display panels are usually created by arranging RGB LED diodes, each with its own light source, on a 320x160mm PCB with certain frequencies in millimeters. After the SMD LED diodes and driver chips of the panel to be produced are lined up, the PCB is covered with a silicon and plastic black frame according to the usage area.

The subject of LED screen production varies according to the viewing distance to the environment where the screen will work. Variables such as viewing distance, power of the light source in the area to be monitored, weather conditions in the environment where the screen will be used, and exposure are taken into account.endüstriyel iç mekan led ekran

Outdoor Led Display

With the advancement of technology, the durability of the IPx level has increased to the IP68 level in LED panel products with the solutions produced by the developers. It has become possible to produce almost waterproof LED screens according to customer demands and outdoor exposure. The solutions in our industry can provide protection at IP64 level by using composite material in the insulation of the back side of outdoor led screens, which are generally produced from panels with IP65 protection on the front that are resistant to rainwater.
The standard IP65 protected panels used in screen construction have a frameless design, which allows us to produce endless and frameless screens resistant to outdoor conditions, depending on the customer's request.

Indoor Led Display

The panels used in indoor LED screen production do not require very high brightness in terms of NITS, and the use of LED diodes that can provide sufficient illumination according to the ambient light, by making them smaller, allows more industrial-style LED diodes to be arrayed on the PCB. Panels with higher pixel density can be combined without bezels to achieve higher resolutions than home displays.

The 8K resolution reached in home electronics today is not sufficient in some cases in the industry, especially in the led screens inside the stores, there is a demand for using larger screens with higher resolution day by day.
It is possible to produce led screens with almost 40K resolution in terms of pixel density and to manage these screens with advanced video processors.
