VA (Vertical Alignment) LCD display screen is an important type in the field of liquid crystal display.
From the perspective of working principle, VA type liquid crystal molecules are arranged perpendicular to the panel when no electric field is applied. When an electric field is applied, the orientation of the liquid crystal molecules changes, thereby controlling the transmittance of light. This principle enables VA display screens to achieve different brightness and color displays.
In terms of contrast, VA displays have significant advantages. It can achieve a very high static contrast, presenting darker dark areas and whiter bright areas, with a stronger sense of hierarchy and depth in the image. This is very advantageous for scenes that require strong visual impact, such as watching movies or playing games.
The viewing angle of VA display screen is also relatively good, although not as good as IPS display screen, it can provide a satisfactory viewing experience in most usage scenarios. However, the response time of VA display screens is relatively long, usually around 6ms to 15ms, which may cause ghosting in rapidly changing image scenes.
In terms of application scenarios, VA displays are widely used in mid to high end televisions, monitors, and other fields. Due to its high contrast, it is very suitable for displaying high-definition video content and can bring users a better visual enjoyment.
