Recently, South Korean media outlet theelec reported that LG Electronics and LG Display (LGD) are jointly developing the 130-inch Micro LED commercial display, Signage. LGD has also joined the research and development project following LG Electronics' change in its Micro LED substrate design.

It is reported that LG Electronics is changing its substrate solution for Micro LED commercial displays from PCB boards to LTPS TFT glass substrates and is developing 130-inch products.
The 22.3-inch LTPS TFT glass substrate Micro LED module required for this product was developed by LGD. By splicing 32 22.3-inch Micro LED modules together, a 130-inch commercial display can be formed. The LED chip size used in this product is no more than 50 micrometers.
It is understood that because of the high electron mobility of LTPS TFT, the driving circuit of each pixel can be integrated inside the panel, thereby reducing signal delay and wiring clutter. In contrast, PCB places the circuit outside the panel, and its performance and efficiency are not as good as LTPS TFT.
Previously, LG Electronics' Micro LED commercial displays all used PCB solutions. This collaboration with LGD may help LG Electronics improve the performance of its Micro LED commercial displays.

It's worth noting that in May of this year, LGD showcased a 22-inch Micro LED display module with a resolution of 480 x 540 and a refresh rate of 48 to 144Hz. Through sliding splicing, the module can form a seamless, ultra-wide display. Some industry insiders believe that this exhibit is similar to the Micro LED module model that LGD is currently developing for LG Electronics.
