For a better understanding of the present invention and to show how it may be carried into effect, reference will now be made to the following drawings, which show the preferred embodiments of the present invention, in which:
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, and the scope of the present invention is expressly not limited expect as specified in the accompanying claims. One skilled in the relevant art will recognize, however, that the invention may be practiced without one or more of the specific details.
Those of ordinary skill in the art will immediately realize that the embodiments of the present invention described herein in the context of methods and schematics are illustrative only and are not intended to be in any way limiting. Other embodiments of the present invention will readily suggest themselves to such skilled persons having the benefits of this disclosure.
The present invention discloses a display device which is utilized a six segments display to show the Arabic numeral 0 to 9, wherein the numeral 7 (seven) is represented by a specific symbol defined by a specified combination of the six segments display. The Arabic numeral 1 to 9 shown in the display may be used for any kind of displaying. Generally, the aim of the digit display is to enter a numeral from 1 (one) through 9 (nine) in each block.
Referring to
The microprocessor 43 may be disposed into the main body, and coupled to the power source 44. The microprocessor 43 may be coupled to a game module 46. The game module 46 comprises a program for generating an electronic game. The electronic circuit 42 may be disposed into the main body, and coupled to the microprocessor 43, the seven display elements 41 and the power source 44. The electronic circuit 42 comprises a pulse-generating means and a plurality of switches coupled to the microprocessor 43 respectively. For example, the display element 41 comprises a layer of liquid crystal material arranged between a pair of electrode plates. The pulse-generating means is adapted to generate a plurality of drive pulse signals for exciting the liquid crystal material to selectively turn the display elements 41 ON and OFF and a plurality of control pulses for operating the switch. Moreover, the switch is adapted to select one of the drive pulse signals to each electrode plate of the pair of electrode plates, and the selected drive pulses is combined to produce a plurality of combined pulses. The combined pulses comprise two different pulse combinations, one of the pulse combinations above the threshold value of the liquid crystal material in effective voltage for a positive display, and another of the pulse combinations below the threshold value of the liquid crystal material in effective voltage for a negative display.
In the present invention, the seven display elements 41 are arranged in a predetermined configuration, shown in
The seven display elements 41 may be shown the data of executing by the microprocessor 43 through the electronic circuit 42 coupled to the seven display elements 41. The microprocessor 43 is coupled to the power source 44 and the keyboard 45 such that the power source 44 can provide a power source to the microprocessor 43 and seven display elements 41 through the electronic circuit 42.
As above-mentioned, the seven display elements 41 are shown by the six segments display such that the display device of the present invention can reduce numerals and the occupied space of the electronic circuits and therefore simplify the driving circuit design. Specifically, the present invention may use lower counts to achieve the purpose that has to be done by higher counts. For example, in 4×4 cells conventional Sudoku game device, it needs 112 (4×4×7=112) control circuits. In the present invention, in 4×4 cells Sudoku game device, it only needs 96 (4×4×6=96) control circuits within 100. In another embodiment, in 9×9 cells conventional Sudoku game device, it needs 567 (9×9×7=567) control circuits. In the present invention, in 9×9 cells Sudoku game device, it only needs 486 (9×9×6=486) control circuits within 500. Accordingly, display device with a six segments display is enormously reducing numerals of control circuits of the display elements
Therefore, in contrast with the prior art having some drawbacks, the present invention provides a new display device which may achieve a purpose for saving numerals of control circuits of the display elements and overcome the above drawbacks.
As will be understood by persons skilled in the art, the foregoing preferred embodiment of the present invention is illustrative of the present invention rather than limiting the present invention. Having described the invention in connection with a preferred embodiment, modification will now suggest itself to those skilled in the art. Thus, the invention is not to be limited to this embodiment, but rather the invention is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims, the scope of which should be accorded the broadest interpretation so as to encompass all such modifications and similar structures. While the preferred embodiment of the invention has been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention.
