128x64 Blue COG LCD Display with ST7565R For C8051-Arduino

This 2.8-inch 128x64 COG display has become a benchmark for the visual presentation of micro devices with its excellent transmissive characteristics and revolutionary integrated design. Its soul lies in the advanced COG (Chip on Glass) process - the core driver chip is directly and precisely encapsulated on the glass substrate. This ingenious design is like "space compression", completely abandoning the PCB board and redundant connection structure required by traditional modules, achieving amazing slimness and miniaturization, freeing up every cubic millimeter of precious space for your industrial instruments, portable medical devices, smart wearables or microcontrollers, giving unprecedented design freedom.

The display effect is its shocking core. This is a pure full-transparent display, and its essence lies in the built-in strong white LED backlight that can completely penetrate the liquid crystal layer. Combined with STN negative display (Negative Display) technology, it presents a classic high-contrast picture with bright white characters on a blue background. This vivid visual presentation ensures that information is clearly captured in an instant, and key data can be sharp and eye-catching even in a quick glance or in an environment with average light conditions. The strong backlight output is its advantage, especially for low ambient light or completely backlight-dependent application scenarios (such as equipment interior, night operation, closed control box) to provide unparalleled clarity and reliability, ensuring that the core information is stable and visible whenever needed, with sharp contrast.

The ease of integration and connection is also commendable. The module is equipped with a standard FPC (flexible printed circuit) interface with metal pins, which truly realizes the revolutionary connection of "plug and play". Developers have completely bid farewell to the cumbersome and error-prone welding steps. Just plug the FPC cable into the corresponding socket and establish a stable and reliable electrical connection in an instant. This not only greatly simplifies the assembly process of the production line, significantly reduces manufacturing costs and potential failure risks, but also makes subsequent equipment maintenance, function upgrades or module replacements extremely simple and efficient, perfectly meeting the needs of rapid development iteration and automated mass production of modern products.

In order to meet diverse application scenarios and aesthetic requirements, the series provides flexible customization options. Users can flexibly choose different display technology solutions including STN (super twisted nematic, providing basic negative display), FSTN (thin film compensation, improving viewing angle and contrast) or DFSTN (double film compensation, optimizing viewing angle and temperature stability) based on comprehensive considerations of contrast, viewing angle, response speed and cost. The appearance color is also rich, such as deep gray and blue (Gray/Blue), classic white and black (White/Black), and mainstream black and white (Black/White), etc., to ensure that the display can be seamlessly integrated into the overall design language of the device. Particularly considerate is its preset viewing angle function - deeply understand the impact of the device installation position on the user's viewing angle (for example, the console needs to be looked up or the handheld device needs to be looked down), the module can pre-set the golden viewing angle of 6:00 (bottom view, optimizing users to watch from above) or 12:00 (top view, optimizing users to watch from below). This means that no matter what typical posture the operator is in, they can get the most natural and comfortable viewing experience, effectively reduce visual fatigue, and improve the comfort of long-term operation. This 2.8-inch fully transparent STN negative COG display is becoming the core engine driving the clear vision of compact smart devices with its high-contrast shocking display, extreme space efficiency and user-first connection convenience.
