240*128 COG LCD Displays

The 240×128 COG LCD Display is a high‑resolution large‑format graphic LCD module featuring 240 horizontal by 128 vertical dots – offering 30,720 individually addressable pixels. This resolution provides exceptional detail for complex user interfaces, detailed waveforms, large data tables, and high‑quality graphics. Built with advanced Chip‑on‑Glass (COG) technology, the driver IC is bonded directly onto the glass substrate using anisotropic conductive film (ACF), resulting in an ultra‑thin, lightweight, and highly reliable display – ideal for applications where thin profile and low power are critical.As a professional China LCD manufacturer, Bolong LCD produces this 240×128 COG display with full in‑house control: we manufacture the LCD glass, perform COG bonding, design and assemble FPC, integrate backlight, and conduct final testing. We offer full customization – from outline dimensions and viewing area to interface, voltage, and even on‑board touch or cover lens.

High‑Resolution Large Graphic Display 240×128
With 30,720 pixels – 275% more than 128×64 – you can display:
16 lines of 5×7 characters – over 480 characters on screen
Detailed real‑time waveforms, spectrum displays, and trend charts
Complex GUI dashboards with multiple data fields and icons
High‑quality bitmap images and company logos
Ultra‑Low Power Consumption
Operating at just 8mA – 18mA with sleep mode below 1µA, this high‑resolution display is surprisingly power‑efficient. Ideal for battery‑powered or energy‑conscious devices.
Flexible Interface Options
SPI : High‑speed serial, up to 10MHz
I²C : Only 2 wires SDA + SCL– saves GPIO pins
8‑bit parallel : Maximum refresh rate for animation or waveform updates
Industrial‑Grade Temperature Range
Standard version operates from -20℃ to +70℃. Industrial‑grade variants rated from -40℃ to +85℃ with wide‑temperature LCD fluid – suitable for outdoor EV chargers and automotive applications.
