LCD segment displays are widely used, with some products deployed in extreme environments such as low temperature, high temperature, strong light, and high humidity. High-durability LCDs are designed to meet the demands of such harsh operating conditions.

This product is a 12864 LCD dot matrix display capable of displaying graphics with a resolution of 128 columns x 64 rows of pixels. The display utilizes an STN mode with an amber LED backlit LCD, presenting amber background with black characters, achieving high contrast and a wide viewing angle. The module contains a dedicated driver chip, adopts COB production technology, and connects to the master MCU via an 8-bit parallel LCD interface for displaying various images and text. The internal compensation circuit ensures excellent display performance even under wide temperature conditions.

Wide-view LCD Segment Display: LCD segment displays typically have a primary viewing angle. Outside this primary viewing angle, contrast ratio differs significantly. The width of the primary viewing angle varies depending on the product type and manufacturing process. The electrical characteristics and environmental parameters of wide-viewing angle products are consistent with those of standard LCD segment displays.
