There's a clear distinction between outdoor inks and regular inks (usually referred to as indoor inks) used on touch screen cover lenses. Choosing the wrong ink material can negatively impact the product's appearance and user experience over time. In this article, the Shenzhen Hongjia Technology team explains how to choose the right ink.

HJ1800-01, a 1.8-inch round LCD with IPS, full viewing angle, 360*360 resolution, and a contrast ratio of 1200. It supports multiple interfaces (SPI/MCU/QSPI/MIPI) via the IM port, and supports an ultra-wide operating temperature range of -30°C to 80°C. The driver IC is the ST77916, and standard ICs are available for a long time. This 1.8-inch round LCD features a capacitive touchscreen and I2C interface. The touchscreen is laminated to the LCD for easy debugging.

Completely eliminating LCD light leakage is difficult (especially against a pure black background, where slight light leakage may occur at the edges). However, through optimized design (such as high-precision shading structures and zoned light control), the use of high-quality materials (such as low-defect light guide plates and high-light-shielding adhesive strips), and rigorous production processes (such as full lamination and precision assembly), light leakage can be significantly reduced.

In the design of small and medium-sized LCD panels, hardware engineers often encounter difficulties in understanding the differences between VCC, VDD, and IOVCC

In short, the 1.9-inch bar-shaped screen is a triumph of functionalism and scenario-based design. It proves that good design isn't necessarily about a larger screen, but about using the right screen in the right place to solve the right problem. It has shifted from being the "center of content display" to becoming a "partner in providing information." This change in role is precisely the fundamental reason for its "great usefulness," making it an indispensable "screw" in the modern hardware ecosystem – small, but crucial.
