WO240128B is a monochrome COG graphic LCD module with a resolution of 240x128 pixels and a diagonal size of 4.8 inches. This COG LCD module WO240128B features a built-in ST7586S controller IC; it supports 6800 8-bit, 8080 8-bit parallel, and 3-line 9-bit / 4-line 8-bit serial SPI interfaces. The WO240128B has the same active area dimensions and view area as the COB WG240128B, but it is much thinner. For customers requiring a thinner 4.8-inch module for new designs, the WO240128B is an excellent choice.
This WO240128B module can operate in temperatures ranging from -20℃ to +70℃, with storage temperatures from -30℃ to +80℃. The WO240128B is available in different LCD mode options, including STN negative blue with white LED backlight and FSTN positive white with white LED backlight. Please contact us if you need other LCD types or LED combinations.
