BOE Expects to Use Mini LEDs to Expand Its TV Presence

BOE wants to be a significant player the Mini LED market and has been developing a range of products starting with 4:3 and 16:9 modules of up to 2.5mm pitch, initially using surface-mounted (SMD) LEDs and developing into COB technologies as well at pitches of 0.925mm, 0.9375mm, 1.23mm and 1.25mm. These products have been based, as most LEDs have been for a long time, on devices mounted on printed circuit boards (PCBs). As well as modular displays, BOE is developing All-in-One or monolithic sets at 110", 136", 164" and 220".

BOE will have two glass-based systems with 0.9375 or 1.25mm pitch. The details are in the table, but note that the physical dimensions are the same, with eight modules per 16:9 cabinet (which are the same size as the BYH series PCB-based cabinets). Note that the individual modules are just 150 x 168.75mm, which means that they are in the range of LTPS (or later, LTPO) technology, so that the transistors on the substrate can be better than AM-LCDs. The move to flexible OLEDs has meant excess capacity in rigid glass LTPS making, which is an advantage in pushing costs down.
