    Back Maintained High Definition Led Display Wall / P3.91 Indoor Led Video Screens

    High Definition Led Display Wall P3.91 Indoor Led Video Screens

    What is Led Display Wall? With directly light emitting leds, Led Display Wall is a group of flat panel display in which the Leds themselves produce the image. This distinguishes direct view led display wall from LED-backlit LCD video wall, in which the Leds serve as a light source only, or DLP video wall, that is based on optical micro-electro-mechanical technology which uses a digital micro-mirror device. As we all know, DLP imaging device was created by Texas Instruments, so the price is also decided by TI. The recent development of micro pixel pitch led displays – which provide much higher resolutions than traditional outdoor led video walls – has allowed this technology to be adapted for indoor applications. As P3.91 Micro Pixel Pitch indoor Led Display Wall needs 65410 pcs SMD2121 led lamps, it commands a higher price than most other display types. However, versatility and high-impact viewing experience have put it in high demand.
