Description
Technical field
It the utility model is related to membrane keyboard technical field, more particularly to a kind of full key board is without rushing formula RGB backlight membrane keyboards.
Background technology
With the development of computer, the update of computer software and constantly upgrading, have become people with computer Entertainment
Using the essential project of computer, in present most computer game, game fight under way bucket often occurs
Situation, so require player also needs to pin in the colleague for pinning directionkeys other keys such as to fight.Prior art
In keyboard typically use matrix form arrangement mode, button can influence each other, and in general keyboard can only support that any 2 buttons are same
When press, if pressing 3 buttons simultaneously, and 3 buttons just in a matrix formed right angle 3 it is angular if because 3 buttons
Path is formed, keyboard will be caused can not to judge which key is pressed.In order to solve this problem, two are concatenated in key switch
For pole pipe come to isolate the mutual influence of button be feasible, this is the multikey or full key board largely used in mechanical key keyboard
Mature technology without punching, but the matrix circuit of membrane keyboard is film, it is difficult to weld diode, so membrane keyboard not into
Ripe realizes the technology of multikey or full key board without punching, and which results in, without keyboard is rushed, must just use machine if necessary to multikey or full key board
Tool keyboard, but not only cost is very high for mechanical keyboard, it is difficult to popularize, and simultaneously, part user, which is often desire to be protruded with backlight, to be shown
Show some buttons specified temporarily, in order to identify, prevent maloperation, only have mechanical keyboard easily to realize on the market at present
State function, although and membrane keyboard also has with backlight function, can only realize that all buttons have backlight or all turned off substantially
Backlight, and it is difficult to realize be arbitrarily designated button and have backlight, and other buttons can turn off the function of backlight.
In summary, existing membrane keyboard is difficult to meet the needs of user to user, and full key board is without punching and backlight work(
It is able to not can coexist.
Utility model content
For weak point present in above-mentioned technology, the utility model provides a kind of full key board without rushing formula RGB backlight films
Keyboard, interactive signal that can be in recognition matrix between row and column effectively handle caused Ghost Key problem in button, effectively identification
Key position, and realize different backlight effects.
To achieve the above object, the utility model provides what is be realized in.
A kind of full key board without rushing formula RGB backlight membrane keyboards, the membrane keyboard include MCU controllers, a plurality of diodes and
A plurality of backlight LED circuits, a plurality of diode arrangements form the diode matrix of 8*18 matrixes, the diode matrix
Electrically connected with the input of MCU controllers, and the output end of the MCU controllers electrically connects with a plurality of backlight LED circuits.
Wherein, a plurality of backlight LED circuits include a plurality of red LEDs, a plurality of green LEDs, a plurality of bluenesss
LED and a plurality of triodes, each red LED, each green LED and each blue led respectively grid with a triode
Pole connects, and the output end of the MCU controllers connects with the drain electrode of corresponding triode respectively, and the source electrode of each triode is equal
Ground connection.
Wherein, the model VS11K07A of the MCU controllers.
The beneficial effects of the utility model are：Compared with prior art, full key board provided by the utility model is carried on the back without formula RGB is rushed
Optical thin film keyboard, MCU controllers carry out the differentiation of button using matrix form key scan 8*18 maximum matrix, pass through two poles
The one-way conduction of pipe come identify the interactive signal between row and column distinguish, so as to handle caused Ghost Key problem in button,
And by the input of MCU controls and the level change of output end come key range position；Also, MCU controllers control plural number
The brightness of individual backlight LED circuit, and then realize different backlight effects.
Brief description of the drawings
Fig. 1 is full key board of the present utility model without the block diagram for rushing formula RGB backlight membrane keyboards；
Fig. 2 is the circuit theory diagrams of each backlight LED circuit.
Embodiment
In order to more clearly state the utility model, the utility model is further described below in conjunction with the accompanying drawings.
Refer to Fig. 1-2, full key board of the present utility model is without rushing formula RGB backlight membrane keyboards, including MCU controllers 1, plural number
Individual diode and a plurality of backlight LED circuits 3, a plurality of diode arrangements form the diode matrix 2 of 8*18 matrixes, diode
Matrix 2 electrically connects with the input of MCU controllers 1, and the output end of MCU controllers 1 is electrically connected with a plurality of backlight LED circuits 3
Connect.
Compared with prior art, full key board provided by the utility model is adopted without formula RGB backlight membrane keyboards, MCU controllers 1 is rushed
The differentiation of button is carried out with matrix form key scan 8*18 maximum matrix, by the one-way conduction of diode come identifying rows
Interactive signal between row is distinguished, so as to handle caused Ghost Key problem in button, and by the inputs of MCU controls and
The level change of output end comes key range position；Also, MCU controllers 1 control the brightness of a plurality of backlight LED circuits 3, enter
And realize different backlight effects.
