OLED is another display technology besides LCD. OLED display is divided into two types: passive matrix OLED (PMOLED) and active matrix OLED (AMOLED). PMOLED addresses and controls pixels in sequence through row and column signals, which is the reason why PMOLED modules have low power consumption. But this control method is only suitable for small sizes, usually below 3 inches. Therefore, AMOLED uses a thin film transistor backplane for control, thereby achieving higher resolution and larger display size.
The biggest difference between OLED and LCD is that OLED can emit light on its own without backlight. This feature means that OLED displays can show pure black without backlight, so they are readable in sunlight and have high brightness.

Although PMOLED display is enough for some simple interface display, color display is the mainstream display interface today, especially for consumer electronics, where color display is more attractive to customers.
If your product has less display content, you may consider a segment LCD display module. Segment LCD is also a low-power, high-contrast display module, and the development of segment LCD is simpler. In addition, the VATN display module can also achieve a full black background effect. Thanks to the color brushed screen process, some fixed color content can be added to the VATN display module screen.
