Refresh rate refers to the number of times a screen image is refreshed per second, which is how many images the screen can display per second. For example, a screen with a refresh rate of 60Hz means it refreshes 60 times per second, in other words, the screen displays 60 frames of content per second.
The refresh rate has a significant impact on the smoothness of the screen, color performance, and user experience. A low refresh rate may cause issues such as operation lag and latency, while increasing the refresh rate can make operations smoother and more natural. A high refresh rate also helps reduce latency, alleviate discomfort such as dizziness and nausea. On high refresh rate screens, image colors are more vivid and bright, and details in dark areas are clearer, enabling more realistic color reproduction. On the contrary, a low refresh rate may cause color ghosting, blurring, and other issues, affecting the visual effect.
Although high refresh rates have many advantages, they may also lead to increased power consumption. Because as the screen refresh rate increases, more computing power is required to render more frames, which leads to an increase in device power consumption and also puts higher demands on the computing power of the driver chip. This is also why although motion blur decreases with an increase in refresh rate, the display screen does not blindly pursue high refresh rates.
Generally speaking, the refresh rate of liquid crystal displays (LCDs) is lower than that of self luminous silicon-based OLED screens. Fast LCD used in VR is a high refresh rate LCD display screen, which typically has a refresh rate higher than traditional LCD displays, reaching up to 90Hz or even 120Hz. Silicon based OLEDs are driven by silicon-based substrate circuits, and their refresh rates can reach up to 120Hz or even exceed 140Hz.
Yunguang Technology adopts digital driving technology, with a display refresh rate of 144Hz. Meanwhile, due to its simple structure, power consumption is minimized, and the driving power consumption is only one-third of that of analog driving.
