What is RGB565?
RGB565, also known as 16-bit RGB, is a color format that uses 16 bits to represent colors, allocating 5 bits for red, 6 for green, and 5 for blue. This format is commonly used in display devices like LCDs and monitors to represent a wide range of colors with lower memory usage compared to RGB888.
The red and blue channels offer 32 shades each, while the green channel provides 64 shades, allowing a total of 65,536 colors. Though RGB565 has lower color depth, it’s more memory-efficient, making it ideal for devices with limited resources.
In contrast, formats like RGB888, which use 24 bits per pixel, can display up to 16.7 million colors, but require more memory.
