What is an OLED display module with 128×64 pixels, and how does it work?

An OLED (Organic Light Emitting Diode) display module with 128×64 pixels refers to a type of display screen that uses organic compounds to emit light when an electric current is applied. The “128×64” specification denotes the resolution of the display, indicating that it has 128 columns and 64 rows of pixels, resulting in a total of 8,192 individual pixels.

OLEDs are self-emissive, meaning each pixel generates its light, unlike traditional LCD displays that require a backlight. When a voltage is applied to a specific pixel, the organic compounds emit light, producing the desired image. This technology allows OLED displays to achieve higher contrast, better color reproduction, and deeper blacks compared to LCDs.
