## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a display apparatus that displays indications, such as the letters of the alphabet, using liquid crystal or Light-Emitting Diodes (LEDs), and, more particularly, to a display apparatus that displays on a display panel the specific letters ┌A┘ to ┌G┘ of the alphabet indicating the musical note, the letters ┌H┘ and ┌L┘ of the alphabet indicating high and low, and Arabic numerals 0 and 1 to 9 using a 12-segment display into which 12 segments are combined, thereby clearly displaying the letters of the alphabet and the Arabic numerals and enabling a viewer to recognize indications rapidly.
2. Description of the Related Art
In general, display apparatuses are widely used to display the functions of various electronic or electrical products, and function to enable users to visually check the status of modes set in response to input signals.
For example, when a user sets a desired mode using a button installed in an electronic product or a remote controller, the electronic product displays the mode on a display apparatus, and thus a user can check the status of a current mode, thereby enabling the user to conveniently use the electronic product.
Hitherto, as shown in FIG. 1, various numerals and the letters of the alphabet have been displayed using a 7-segment display 100 in which seven segments 100a, each formed in a long bar shape and of liquid crystal or an LED, are combined together in a figure-8 shape.
However, although the above conventional 7-segment display 100 can correctly display the Arabic numerals, it is problematic in that it cannot clearly display letters of the alphabet, that is, letters of the English alphabet.
Meanwhile, a guitar is a musical instrument that is played by the strumming of a plurality of guitar strings. There are generally six guitar strings arranged in parallel to generate different notes. After the guitar strings have been strung, each of the guitar strings is tuned by the turning of a peg so that a unique note is generated by each string.
In order to express the notes of the seven-note that are sounded when the guitar strings are tuned, the seven letters ┌A┘ to ┌G┘ of the alphabet are used. In the case of C major, ┌A┘ is a musical note indication indicating ┌La┘, ┌B┘ is a musical note indication indicating ┌Si┘, ┌C┘ is a musical note indication indicating ┌Do┘, ┌D┘ is a musical note indication indicating ┌Re┘, ┌E┘ is a musical note indication indicating ┌Mi┘, ┌F┘ is a musical note indication indicating ┌Fa┘, and ┌G┘ is a musical note indication indicating ┌Sol┘.
In general, a first guitar string from the bottom is tuned to generate the note ┌E┘ in the state in which guitar strings are not pressed against the fingerboard, a second guitar string is tuned to generate the note ┌B┘ in that same state, a third guitar string is tuned to generate the note ┌G┘ in that state, a fourth guitar string is tuned to generate the note ┌D┘ in that state, a fifth guitar string is tuned to generate the note ┌A┘ in that state, and a sixth guitar string is tuned to generate the note ┌E┘ in that state. The guitar strings may also be indicated using Arabic numerals 1, 2, 3, 4, 5 and 6.
A performer tunes six guitar strings in such a way as to generate unique standard notes while pressing the guitar strings on the fingerboard and generating various notes. There is a problem in that the seven letters ┌A┘ to ┌G┘ of the alphabet indicating the notes of the guitar strings cannot be indicated clearly using the conventional 7-segment display 100 mentioned previously.
As described above, according to the prior art, note indications in the forms of the letters of the alphabet representing the notes of the guitar strings cannot be clearly indicated, so that a performer who tunes the guitar strings cannot easily recognize the note indications.
SUMMARY OF THE INVENTION
Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a display apparatus which can clearly indicate guitar string musical note indications ┌A┘ to ┌G┘ , the letters ┌H┘ and ┌L┘, and Arabic numerals 0 and 1 to 9 on a screen, so that a performer who tunes the guitar strings can recognize the musical note indications easily and rapidly.
In order to accomplish the above object, the present invention provides a display apparatus for displaying indications using liquid crystal or Light-Emitting Diodes (LEDs), the display apparatus comprising a 12-segment display including 12 liquid crystal or LED segments, wherein the 12-segment display includes a first segment horizontally disposed on the upper side of the 12-segment display and configured to have an inverted trapezoidal shape; a second segment disposed under the right end of the first segment in a downward direction and configured to have a parallelogram shape; a third segment disposed under the second segment and configured to have an isosceles triangle shape with a radially inwardly disposed apex; a fourth segment disposed under the third segment in a downward direction and configured to have a parallelogram shape; a fifth segment horizontally disposed beside the bottom end of the fourth segment in a left direction and configured to have a trapezoidal shape corresponding to the shape of the first segment; a sixth segment disposed over the left end of the fifth segment in an upward direction and configured to have a parallelogram shape corresponding to the shape of the fourth segment; a seventh segment disposed over the sixth segment and configured to have an isosceles triangle shape with a radially inwardly disposed apex; an eighth segment disposed between the top end of the seventh segment and the right end of the first segment and configured to have a parallelogram shape corresponding to the shape of the second segment; ninth and tenth segments horizontally disposed between the segments having an isosceles triangle shape and configured to have a square shape; and eleventh and twelfth segments respectively disposed on the upper and lower sides of the ninth segment and configured to have a square shape.
Gaps may be disposed between the respective segments.
Outside corners formed by the first segment and the eighth segment, the first segment and the second segment, the fourth segment and the fifth segment, and the fifth segment and the sixth segment may be cut away to form bevels.
The display means of the 12-segment display 10 may be inclined to the right.

FIG. 5 is a perspective view of a guitar including the equalizer of FIG. 4. FIG. 6 is a state diagram showing a state in which a specific note indication is displayed on the screen of the display apparatus of FIG. 4.
A display apparatus A equipped with the 12-segment display 10 of the present invention as described above is useful for a tuner for a guitar using letters ┌A┘, ┌B┘, ┌C┘, ┌D┘, ┌E┘, ┌F┘ and ┌G┘ of the alphabet indicating seven musical notes. The display apparatus A is included in an equalizer 1 for controlling tone. The equalizer 1 is disposed on a side of a guitar body. In the tuning of a guitar, a note issued when a guitar string 2 is strummed is displayed on a display panel B, and the pitch of the note is adjusted using a peg 3.
The 12-segment display 10 is placed at the center of the display panel B, and displays the above seven letters of the alphabet. FIG. 6 shows a state in which ┌D┘ indicating note ┌Re┘ is displayed as an example.
Although the 12-segment display 10 of the present invention may be useful in display apparatuses for a tuner, an equalizer, an amplifier and a pedal, which are guitar components, it is not limited thereto and may be applied to all display apparatuses.
The display apparatus of the present invention includes the third segment having an isosceles triangle shape disposed between the second segment and the fourth segment, the seventh segment having an isosceles triangle shape disposed between the eighth segment and the sixth segment, and ninth, tenth, eleventh and twelfth segments having a square shape disposed on the inner side of the eighth and sixth segments, so that not only note indications, that is, the letters ┌A┘ to ┌G┘ of the alphabet, but also other letters of the alphabet and the Arabic numerals can be clearly displayed on a display screen, with the result that a player can rapidly and accurately discern the displayed tuning status while tuning guitar strings.
