Featuring a 64\u00d732 resolution and driven by the SSD1306 controller IC, this OLED display provides crisp text and graphics with excellent readability.<\/p>\n<p data-start=\"476\" data-end=\"804\">Built using OLED self-emitting technology, the module requires no backlight, resulting in lower power consumption and a thinner structure compared to conventional LCD displays. With an extremely wide viewing angle and high brightness performance up to 150 cd\/m\u00b2, the display maintains clear visibility from different directions.<\/p>\n<p data-start=\"806\" data-end=\"1049\">The module supports a 4-wire SPI communication interface and operates at a single 3.3V power supply, allowing easy integration into wearable devices, portable electronics, medical instruments, industrial control systems, and smart IoT devices.<\/p>\n<p data-start=\"1051\" data-end=\"1214\">As a professional OLED and TFT LCD manufacturer, QIHAN also supports customization services including interfaces, FPC design, display color, and OEM\/ODM solutions.<\/p>\n<h2 data-section-id=\"qhhk8d\" data-start=\"1221\" data-end=\"1242\">Highlights<\/h2>\n<ul>\n<li
