Is the higher the refresh rate, the better?

The refresh rate refers to the number of times the screen image is refreshed per second, that is, how many images the screen can display per second. For example, a screen with a 60Hz refresh rate means it is refreshed 60 times per second, in other words, 60 frames of content are displayed on the screen per second.

The refresh rate has an important impact on aspects such as picture smoothness, color performance, and user experience. A low refresh rate may lead to problems such as operation stuttering and latency, while increasing the refresh rate can make the operation more smooth and natural. A high refresh rate also helps to reduce latency and alleviate dizziness and nausea. On a high-refresh-rate screen, the image colors are more vivid and bright, and the details in the dark areas are also clearer, enabling a more realistic color reproduction. Conversely, a low refresh rate may cause problems such as color smearing and blurring, affecting the visual effect.

Although a high refresh rate has many advantages, it may also lead to increased power consumption. Because when the screen has a higher refresh rate, more computing power is required to render more frames, resulting in an increase in device power consumption and also placing higher demands on the computing power of the driving chip. This is also the reason why, although the motion blur decreases as the refresh rate increases, the display screen will not blindly pursue a high refresh rate.

Generally speaking, the refresh rate of LCD screens is lower than that of self-luminous Micro-OLED screens. The Fast-LCD used in VR is a type of high-refresh-rate LCD. Its refresh rate is usually higher than that of traditional LCD displays and can reach 90Hz or even 120Hz. The Micro-OLED is driven by a silicon-based substrate circuit, and its refresh rate can basically reach 120Hz or even above 140Hz.

Lumicore uses digital driving with a refresh rate of 144Hz. At the same time, due to its simple structure, it minimizes power consumption, and the driving power consumption is only one-third of that of analog driving.
