Abstract

The invention provides an array light source simple character input method in which a simple character can be inputted by two or three keys. The key group consists of two or three keys and a plurality of LED arrays capable of giving off three base colors of red, green and blue; and characters which are preset to be inputted and printed in various colors corresponding to colors of the light given off by LEDs are arranged near the LED. The method comprises the following steps: two particular keys of the key group are pressed at the same time, the character input state is entered, each LED of the array light source can orderly taken turns to be lighted and give off light in various colors under the control of the keys, the keys are selected according to the defined direction, the positions and colors of the lighted LEDs of the array light source are selected; and when the color of the LED is the same as that of the character printed in the same color, and the character needs to be inputted, a particular confirm key is pressed, and the character is completely inputted. By repeating the steps, a plurality of characters can be inputted.

Description

Array light source simple character input method

Technical field

The invention relates to a kind of character entry method, refer to a kind of simple character input method that array light source shows that is adapted to especially.

Background technology

Current various novel electron display screen emerges in an endless stream, the disclosed a kind of array light source mobile imaging display device of Chinese patent Granted publication CN2277548Y, display device is when fast moving, under computer chip (CPU) control of array light source (LED array) in electronic circuit, can light or extinguish being pre-stored in character information follow procedure in the electronic circuit storer (RAM), just can see the character information that prestores according to the persistence of vision principle.Revise Word message to this display device, need Connect Power usually brain or PDA(Personal Digital Assistant) carry out the character input, change the memory content of display device, use very inconvenient.If character input system is also fitted together with display device, use will be convenient, but because existing various character entry methods all need a keyboard operation about 10 keys, so certainly will increase the complexity of whole device, especially want cube can not be too big the time when display device, just be difficult to be provided with a so many key board, need two or three buttons of a kind of need just can import simple and easy English character input method.

Summary of the invention

The invention provides a kind of array light source simple character input method, only need two or three buttons just can finish the simple character input

To achieve these goals, simple character input method provided by the invention, this key groups comprises 2 to 3 buttons, and can send respectively by most that light emitting diodes row red, green, the basket three primary colours are formed battle array, the character that can import is preset in the representative of the corresponding color printing of light color that sent with several and light emitting diode on each light emitting diode next door, and the method comprising the steps of:

Specific two keys in the while pressing keys group, enter the character input state, each light emitting diode is by lighting by turns successively under the key control and with several colour light emittings in the array light source, with the direction options button that wherein defines, the position and the color of array light source light emitting diode lighted in selection, identical and be again when desiring input character when its color and next door with the character of color printing, by specific acknowledgement key wherein, finish a character input.Repeat above step and can finish a plurality of character inputs.

Described simple character input method, with the direction options button of definition wherein, whenever to light by this key once light emitting diode of conversion successively, the bright mistake of permutation is once, can change a kind of color next time and light successively again, select the array light source light emitting diode to light position and color with this.

Described simple character input method, when the array light emitting diode adds up to n, but default input character adds up to m, every light emitting diode can send k kind color of light, each row in the other printing of array light emitting diode can reach n with the color character, are all default input character of definable as long as satisfy kn 〉=m.

Described simple character input method, pushing the direction options button selects array light emitting diode to certain pipe to light, when lighting, that light emitting diode of array extreme position continues to push this key again when choosing, just be rotated to other end extreme position light emitting diode and light and change a kind of color, represent to select another row character with this.

Described simple character input method when the character that the needs deletion has just been imported, can be pressed wherein certain two particular key simultaneously, can finish character of deletion.

Described simple character input method when the whole characters of input of needs deletions, can press simultaneously that wherein certain two particular key is double, can finish Delete All.

Described simple character input method, its direction options button can adopt one to two key, can only be by the direction selection character that goes round and begins again with a direction options button; But select accelerating selection character speed with both direction options button fore-and-aft direction.

Described simple character input method enter those two particular key of character input state as long as repeat to press simultaneously, but with regard to the termination character input state, operation circuit will store down the content of importing.

Simple character input method of the present invention also can be applicable to require a small amount of button just can import the simple character occasion as instrument and meter, toy, household electrical appliance etc.
