In recent years, LED screens have replaced LCDs in indoor environments, especially in wide spaces where clear images need to be captured from long distances and side angles. Depending on the viewing distance and the size of the screen, products with different pixel pitches can be selected.

In previous years, P5 and P4 panels were predominantly used indoors, but more recently, P3, P2.5, P2, and even P1.86 panels have become preferred. In some special projects, P1.66, P1.53, and P1.25 panels are used. For example, Led Ajans primarily uses P2 panels in its desktop menu boards/menu board LED screens, but it has used P1.25 panels for custom requests. In earlier years, P6 panels were widely used because the cost difference between P6 and P5 panels was minimal. However, with advancements in LED and LED screen technology, P6 panels are almost no longer used in LED screens, while P5 panels are now mainly chosen for larger LED screens or lower-budget projects. Led Ajans predominantly uses P2 and P2.5 modules in indoor LED screens, and P2.5 indoor LED screen modules are the most sold in module sales. For Poster LED Screens / Totem LED Screens, 64×160 cm and 64×192 cm vertical, magnetically structured enclosures with P1.86, P2, and P2.5 RGB LED modules are predominantly used. While live broadcasting on indoor LED screens was previously only possible with the help of a processor, with companies producing LED screen control cards (such as Novastar and Huidu) adding processor capabilities to their asynchronous cards, LED screen control cards can now perform live broadcasting by scaling without a processor, offering both synchronous and asynchronous features. Examples of these LED screen control cards include the Novastar Taurus series (TB1, TB2, TB3, TB4, TB6, TB8) and the Huidu series (HD-A4, A5, A6), which are frequently used in LED screens in Turkey. Furthermore, Huidu has added a new feature to its A4, A5, and A6 LED screen control cards, allowing LED screens to display live broadcasts and preloaded videos, images, etc., simultaneously. This enables LED screens to be divided into pixel dimensions and used for different purposes with different images. Additionally, options such as sound systems, temperature sensors, humidity sensors, wind sensors, and pressure sensors can be integrated as desired. Indoor LED screens generally use thin enclosures and fanless SMPS to reduce noise. Due to the increased scan rate and lower current draw of the LEDs, indoor LED screens require less power and, consequently, fewer power supply adapters. Typically, one 200-5 (40-amp) power supply adapter is used for every 8 indoor LED screen modules.
