The viewing angle range of a VGA liquid crystal display refers to the extent to which the picture quality is worse than that at the central viewing angle when the screen is observed within the viewing angle range. Specifically, the viewing angle range refers to the range in which the color, brightness, contrast and clarity can be kept highly consistent when the viewing point is moved from the center point to the left or right or up and down on the screen.

The viewing angle range that current liquid crystal technology can achieve largely depends on the characteristics of liquid crystal technology itself. Generally speaking, there are two types of liquid crystal technology at present: TN (Twisted Nematic) and IPS (In-Plane Switching). Among them, TN liquid crystal display is cheap and has fast response time, but its viewing angle range is small, usually 160°/170°, that is, when viewed at 160 to 170 degrees away from the center point in the horizontal and vertical directions, the screen color, brightness, etc. Severe losses can result, resulting in reduced visual quality.

The IPS liquid crystal display, because of its high aperture ratio, can provide a wider viewing angle, and its viewing angle range can reach 178 degrees (horizontal/vertical), and there are also cases of 256 degrees (diagonal). Moreover, the color reproduction of the IPS screen is more accurate, which is more suitable for professional image and video editing work.

It should be noted that although the viewing angle range of IPS liquid crystal display is relatively wider, its price is also relatively expensive. Therefore, when purchasing an LCD monitor, you should comprehensively consider your actual needs and budget, and choose a product that meets your needs.

In short, the viewing angle range of VGA liquid crystal display is closely related to liquid crystal technology and product price. For specific application scenarios and purposes, you should choose products with appropriate viewing angles, reasonable prices, and reliable quality.
