Abstract:
1. A method of displaying tuned states of guitar strings, comprising the following steps: providing a display device, the display device including an LCD panel provided in an equalizer mounted to a guitar body, and configured to display the tuned states of the guitar strings; providing a backlight mounted behind the LCD panel; providing a control unit configured to control the LCD panel and the backlight; providing a buffering member interposed between the backlight and the control unit for protecting the LCD panel and backlight; performing a first control step by the control unit, wherein during said first control step, the backlight emits light having a predetermined color by turning on the backlight when a tuner is turned on; performing a second control step by said control unit after completion of said first control step by the control unit, wherein during said second control step the backlight emits light having a different color when tuning of the guitar strings is completed; displaying a central reference indication representing a reference pitch of said guitar on said LCD panel when the tuner operates, wherein when the pitch of a guitar string is too low relative to said central reference indication, an arrow indication is displayed on the LCD panel spaced apart and to the left of the central reference indication, wherein a position of said arrow indication approaches the central reference indication as the guitar string pitch approaches the reference pitch, and wherein when the pitch of a guitar string is too high, the arrow indication is displayed on the LCD panel spaced apart and to the right of the central reference indication, such that as the pitch of the guitar string increases, the position of said arrow indication approaches the central reference indication as the guitar string pitch approaches the reference pitch.
