Embodiment
In conjunction with the accompanying drawings and embodiment, as follows to the detailed description of the invention.
Fig. 1 is that the present invention controls two groups of circuit diagrams that LED is luminous.As shown in the figure, LED1101, LED2102, LED3103, LED4104 are one group of luminous under figure pattern light-emitting diodes; LEDa105, LEDb106, LEDc107, LEDd108 are one group of luminous under alphabetical stroke pattern light-emitting diodes.Every group of LED inside all is connection parallel with one another, the positive pole of LED1-4 connects DC power supply, negative pole connects the collector terminal of transistor Q1A109, the emitter terminal ground connection of transistor Q1A109, the base terminal of Q1A109 and DBB (Data BaseBand, digital baseband) 111 GPI (general purposeinterface, general purpose interface) O1 connects, the positive pole of LEDa-d connects DC power supply, negative pole connects the collector terminal of transistor Q2A110, the emitter terminal ground connection of Q2A110, the base terminal of Q2A110 is connected with the GPIO2 of DBB.Under different input patterns, DDB111 control LED1-4 is bright, LEDa-d goes out or LED1-4 goes out, LEDa-d is bright.
Fig. 2 is a control flow schematic diagram of the present invention.As shown in the figure, after the mobile terminal-opening initialization finishes, may further comprise the steps:
S201 checks which kind of input pattern input state is in;
S202 judges whether input pattern is digital input pattern;
S203, if digital input pattern, GPIO1 is a high level, transistor Q1A conducting, LED1-4 is luminous, and GPIO2 is a low level, and transistor Q2A disconnects, and LEDa-d is not luminous;
S204, if not digital input pattern, GPIO1 is a low level, and transistor Q1A disconnects, and LED1-4 is not luminous, and GPIO2 is a high level, transistor Q2A conducting, LEDa-d is luminous;
S205, the user is switched input pattern, and returns S201.
Fig. 3 is the structure chart of the keyboard of known technology.Fig. 4 and Fig. 5 are the work schematic diagrames of LED arrangement on the keyboard of the present invention.As shown in the figure, on traditional keyboard, numeral is on the right side of letter and other nonnumeric characters, and in the present invention, centre one row of keyboard have been changed the traditional order of numerical character and alphabetic character or stroked character, among Fig. 3, Fig. 4, it is the right side that " 2 " is located at " abc ", " 5 " are located at the right side of " jkl ", " 8 " are located at the right side of " tuv ", like this, " 2,5,8 " are listed as once row and " 3,6,9 " and become adjacently, and " abc, jkl, tuv " one row are adjacent with " ghi, pqrs " row.Design is in order that reduce the usage quantity of LED like this.Two groups of LED are arranged on the keyboard, the LED1-4 of light design is in the position of contiguous numerical chracter under figure pattern, the LEDa-d of light design is in the position of contiguous letter under other input patterns, if the stroke symbol is arranged on the keyboard, also can design from the near position of stroke.When input pattern was figure pattern, LED1-4 was luminous, and the numerical character of four light-emitting diodes of contiguous LED1-4 is brighter than alphabetic character on keyboard; At input pattern is not under the situation of figure pattern, and the letter character that is respectively adjacent to LEDa-d is brighter than numerical character.Thereby make the incoming symbol that the user can see more clearly needs use under different input patterns.In Fig. 3, Fig. 4, in the left side of keyboard, promptly the left side of " 1,4,7 " on the button is provided with one group of light-emitting diode luminous under digital input pattern between " 3,6,9 " and " 2,5,8 "; On the right side of " def, mno, wxyz ", between " abc, jkl, tuv " and " ghi, pqrs " one group of light-emitting diode luminous under nonnumeric pattern is set.
In the portable terminal use of reality, except the occasion of many acquiescence input patterns is arranged, also has the indefinite occasion of some input patterns, in the process of playing games, in the process of browsing page, under these situations, for saves energy and be user-friendly to, one group of lumination of light emitting diode should be arranged to have only, all digital input pattern setting can be contrasted usually, because, call is to dial by numeral, and for example in the rule declaration of recreation, state the user usually as by numerical key, as " 2 " expression upwards, downward or the like by " 8 " expression.Certainly, it is all luminous or not luminous also can be arranged to two groups of light-emitting diodes in different occasions.
Fig. 3 and LED arrangement shown in Figure 4 are a kind of situation in the present invention design, and promptly the character arrangements of Zhong Jian a row keyboard is with traditional opposite, and digital and letter reverses the right order.In addition, the possibility that also has another kind of design, promptly left side one row and the numeral above the one row keyboard of right side and letter are arranged and are reversed the right order, and middle row are constant, between contiguous numerical chracter and nonnumeric symbol, light-emitting diode is set respectively again, so also can reaches goal of the invention of the present invention.Certainly, as shown in the figure, the position that each row is provided with light-emitting diode also is not limited in two, can be provided with a plurality of, in a word, on the arrangement of LED, as long as behind the LED light, can divide digit number and nonnumeric symbol, all can design consideration by brightness region.
In concrete design is produced,, can add the more LED of more number in the Position Design that LED is set for brightness and the color that makes symbol reaches requirement.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; being familiar with those of ordinary skill in the art ought can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
