[Display Glossary.zip] EP.17 : Viewing Angle
The viewing angle is a numerical measure of the difference in image quality when the display screen is viewed from the right, left, above, and bottom, as compared to the front. Depending on the product, a monitor or TV screen that appears clear when viewed from the front may often look darker or dull when viewed from the side or above.
Generally, light travels in a straight line, meaning that display brightness and color are affected depending on the viewing angle. LCDs, which use a backlight that passes through a liquid crystal and color filter, have more limited viewing angles compared to self-emissive displays. On the other hand, self-emissive QD-OLED displays emit light uniformly in all directions, providing consistent brightness and color accuracy, regardless of the viewing angle.
Displays with poor viewing angles can suffer from color distortion or reduced brightness when viewed from the side, making it difficult to enjoy optimal picture quality. The better the viewing angle of a display, the more consistently you can enjoy the same picture quality, regardless of your viewing position.
