OLED (Organic Light Emitting Diode) and AMOLED (Active Matrix Organic Light Emitting Diode) are both types of display technologies that use organic compounds to emit light. OLED and AMOLED displays are very similar, but there are some key differences between the two:
(1) Sub-pixels: OLED displays have three sub-pixels (red, green, and blue) for each pixel, while AMOLED displays have an additional layer of transistors that control each individual sub-pixel. This allows AMOLED displays to produce brighter and more vibrant colors.
(2) Power consumption: AMOLED displays are more power-efficient than OLED displays, as they only turn on the pixels that are needed to display the image. This means that black areas of the screen are completely turned off, resulting in deeper blacks and better contrast.
(3) Production cost: AMOLED displays are more expensive to manufacture than OLED displays, as they require an additional layer of transistors. This is why AMOLED displays are typically found in higher-end smartphones, while OLED displays are more common in mid-range and budget-friendly devices.
(4) Viewing angles: AMOLED displays have wider viewing angles than OLED displays, as each pixel can emit its own light. This means that colors remain consistent even when viewed from different angles.
Overall, AMOLED displays offer several advantages over OLED displays, including brighter and more vibrant colors, more efficient power consumption, and wider viewing angles. However, OLED displays have advantages such as longer lifespan and better uniformity. OLED displays also tend to be more affordable, making them a popular choice for mid-range and budget-friendly devices. Ultimately, the choice between OLED and AMOLED displays depends on the specific needs and preferences of the user, as both technologies offer excellent image quality and are commonly used in high-end smartphones and other mobile devices. by ifixparts.com
