LED Screens


LED TVs are in practice LCD screens using a rear lighting via LEDs. This allows them to have an excellent image in all kinds of environments, higher contrast, and even in very bright environments, their performance is superior, Are more economical, lightweight and easy to install.



They have a fantastic reproduction behavior of any type of content, since they particularly enhance,  blacks and whites in the images. Their Quality is the one which is more closely approximated to the picture quality of plasma and in turn they have the other advantages that one does not have.



There are three types of LED lighting:



White LEDs all around the screen using a special diffuser Panel to spread the light of choice behind the screen.

Led panel behind the screen whose brightness is controlled not individually

Dynamic Panel controlled individually or in small blocks which allows for rear illumination modulated patterns.



The third is the most efficient in terms of quality and also the most expensive.



The acronym siglifica LCD Liquid Crystal Screen IE Dysplay Liquid crystals and LED Ligth means Emiting diode Diode, or led.


Three types of LED may be used:




    • White-edge LEDs around the rim of the screen, using a special diffusion panel to spread the light evenly behind the screen (the most common use)


    • LED array behind the screen, whose brightness is not controlled individually


    • Dynamic “local dimming” array of LEDs, controlled individually (or in clusters) to achieve a modulated backlight pattern




The third one  is the most efficient in terms of quality and also the most expensive.



The acronym LCD stands for  Liquid Crystal Screen and  LED Ligth  Emiting  Diode.
