128x64 inch Gralhic LCD Display - FSTN(+)Black on white - ST7565R -Arduino
The core secret of this 12.8-inch 128x64 resolution COG display lies in the revolutionary COG (Chip on Glass) process. This technology precisely encapsulates the key driver chip directly on the glass substrate, completely eliminating the additional PCB board and connection space that traditional display modules rely on. This structural design achieves the ultimate compression of volume and thickness, freeing up valuable internal space for compact devices that are extremely sensitive to space, such as industrial instruments, portable medical devices, smart wearables, and microcontrollers.
The gray FSTN (+) polarizer and white backlight configured by it form a visual style that clearly displays dark gray fonts on a white background. In order to greatly simplify the developer and production process, this series of products is equipped with a standard FPC (flexible printed circuit) interface with metal pins, creating a truly "plug and play" connection experience. Users do not need to perform delicate and error-prone welding operations, but only need to easily insert the FPC cable into the corresponding socket to complete a reliable electrical connection. This not only significantly simplifies the production and assembly process and reduces the potential failure rate, but also greatly facilitates subsequent maintenance and equipment upgrades, perfectly meeting the needs of modern automated production and rapid product iteration.
In terms of display mode, this 2.8-inch COG display adopts an innovative transmissive mode and has the ability to intelligently adapt to ambient light. When the ambient light is dim, the built-in white LED backlight can efficiently penetrate the liquid crystal layer to provide a bright and clear positive display effect (black text on a white background), ensuring that key information always maintains reliable visibility in various scenarios, from the inside of a dimly lit industrial control cabinet to the shadow area of outdoor equipment. In an environment with strong natural light, the screen can use its reflectivity to effectively reflect the image to the user, ensuring that the content can also be clearly read in a bright environment, thereby achieving stable operation in all scenarios.
In order to meet the diverse needs of different application scenarios, users can flexibly choose different display technologies such as STN (super twisted nematic), FSTN (thin film compensation) or DFSTN (dual film compensation) according to factors such as contrast, viewing angle, response time and cost. The appearance color scheme also provides a rich selection, such as gray/blue, classic white/black, black/white, etc., so that it can perfectly integrate into the overall design language of the device. Particularly considerate is its viewing angle preset function - taking into full consideration the impact of the actual installation location of the device on the user's viewing angle (for example, if it is installed below the console, the user needs to look up, or if it is installed on the top of the instrument, the user needs to look down), the module can preset an optimized viewing angle of 6:00 (bottom view, suitable for devices installed above the user) or 12:00 (top view, suitable for devices installed below the user) according to the specific installation location. This design ensures that the end user can get the most natural and comfortable reading experience in any typical operating posture, effectively reducing visual fatigue.
