Refresh rate refers to the number of times per second the screen image is refreshed, or how many frames per second the screen can display. For example, a 60Hz refresh rate means the screen refreshes 60 times per second, displaying 60 frames of content per second.

Refresh rate has a significant impact on image smoothness, color representation, and overall user experience. Low refresh rates can lead to stuttering and lag, while higher refresh rates enable smoother, more natural operation. High refresh rates also help reduce latency and minimize feelings of dizziness or nausea. On high refresh rate screens, colors appear more vibrant and bright, with better visibility of dark details for a more realistic representation. Conversely, low refresh rates can cause color trailing, blurriness, and other visual artifacts.

While the benefits of high refresh rates are numerous, they can also increase power consumption. This is because the higher refresh rate requires more processing power to render the additional frames, leading to increased power draw and higher demands on the driving chipsets.

Generally speaking, LCD screens have lower refresh rates than self-emissive Micro-OLED and Micro-LED displays. VR uses a type of high refresh rate LCD called Fast-LCD, which can reach 90Hz or even 120Hz, while Micro-OLED can achieve refresh rates of 120Hz or higher.

Lumicore's digital driving technology plays a remarkable role in enhancing refresh rates while also minimizing power consumption through its streamlined design.
