What Are the Key Features of a 1604 16x4 Character LCD Display Module?

A 1604 16x4 character LCD displays 16 characters per line across 4 lines, ideal for compact text output. These modules often use HD44780-compatible controllers, feature black text on a yellow-green background, support 5V or 3.3V power supply, and operate via a parallel interface. Some variants include I2C interfaces for simpler wiring. Viewing angles and controller types vary but commonly include AIP31066, KS0066, and SPLC780.

Such specifications ensure compatibility with various microcontrollers, including Arduino, making these modules versatile for embedded displays in electronics projects or industrial applications.

Where Can You Buy Affordable 1604 16x4 Yellow-Black LCD Modules?

Affordable 1604 16x4 yellow-black LCD modules can be purchased from multiple online sources:

Among these, Panox Display also offers cost-effective custom and standard LCD modules with guaranteed quality and OEM support for professional needs.

How Compatible Are These LCD Modules with Microcontrollers and Power Supplies?

Most low-cost 1604 LCD display modules operate on industry-standard HD44780-compatible controllers, making them directly compatible with popular microcontrollers like Arduino, Raspberry Pi (with adapters), and others. They typically support both 5V and 3.3V power inputs, providing design flexibility.

Additionally, modules with I2C interface boards reduce wiring complexity, which is beneficial for compact hardware setups. This compatibility ensures easy integration in DIY projects and prototyping, as well as in commercial products.

Why Choose Yellow-Black LCD Displays Over Other Colored Screens?

Yellow-black LCD displays feature black text on a yellow-green background, offering excellent contrast and readability under various lighting conditions. This makes them ideal for outdoor or industrial environments where glare and ambient light reduce screen visibility.

Compared to blue or white backlit screens, the yellow-black combination minimizes eye strain during long-term data reading. Panox Display specializes in offering these high-contrast modules suited for demanding applications in automotive, military, and wearable devices.

Which Controllers Are Commonly Found in 1604 16x4 LCD Modules?

Common controller chips found in 1604 16x4 LCD character modules include:

• HD44780

• AIP31066

• KS0066

• SPLC780

• ST7066

These controllers manage the LCD operation, character generation, and interface communication. HD44780 is the standard for compatibility, while others offer minor variations or are equivalent clones. Knowing which controller is used helps ensure compatibility with your microcontroller firmware and libraries.

How Does Viewing Angle Affect the Usability of 1604 LCD Modules?

The viewing angle of standard STN LCD modules in yellow-black is typically wide enough for most applications, though it varies between manufacturers. Reduced viewing angles can cause text to appear dim or inverted when viewed from extreme sides.

Panox Display products are tested for adequate viewing angles, ensuring legibility in various positions, crucial for handheld devices, dashboards, and industrial controls.

What Are the Advantages of Buying from Panox Display?
