Abstract
The driving voltage of a liquid crystal display can be adjusted by irradiating the liquid crystal fluid in the display with ultraviolet light. After the fluid is placed in the display, it is exposed to a predetermined dose of high intensity ultraviolet light. The ultraviolet light alters the chemical composition of the fluid, thus changing the switching voltage of the fluid and the driving voltage of the display.
