Relate to a kind of backlight keyboard that can on each button, show variable information by the keyboard that changes change button prompting information backlight, the problem that the information that purpose is to solve on the keyboard and is identified can't change.The present invention is made of the optical processing material on keyboard back light light source that can produce the heterogeneity light wave and the keyboard cover, by changing the keyboard back light state, makes the optical processing material show different information patterns.The invention solves the information that identifies on the keyboard cover can't change, and is difficult to mark the problem of bulk information on the keycap.
Description
Technical field
Patent of the present invention relates to a kind of backlight keyboard that can show variable information on each button, it specifically is exactly a kind of keyboard back light light source that can pass through to switch different light wave character, selectivity by the different optical processing materials on the keycap is handled, and makes keyboard cover show the keyboard of different information patterns when activating different back lights.
Background technology
Because keyboard is made up of a plurality of buttons, each button has different operating functions, and for avoiding taking place maloperation, all etchings or be printed with information on each button keycap of keyboard or near the prompting nameplate of button are to illustrate the concrete function of each button.When the function of the required realization of input equipment is a lot, when input information was very complicated, the design of keyboard had just run into the conflicting problem of intuitive and ease for use.Specifically in other words, when keyboard need be imported a large amount of different information, deviser or should design a large amount of buttons made the corresponding a kind of function of each button.Be difficult to remember the function of each button because button is a lot of this moment, thus need be on the keycap of each button or nameplate the function (as the letter key on the computer keyboard) of this button of mark; Perhaps should design a small amount of button, combinatorial input by a plurality of buttons or button and menu allows a small amount of button realize a large amount of functions (add the combinatorial input of other buttons as " shift key " on the computer keyboard, and the design of numerical key, letter key and stroke bonding one on the cell phone keyboard).These two kinds of methods for designing all have limitation: though the former is directly perceived, a large amount of key arrangement is not suitable for learning and mastering and carries out quick input operation, and both ease for use was relatively poor; Then a kind of design needs a large amount of Macintosh of memory because intuitive is relatively poor, easily because of promnesia causes maloperation, or need mark bulk information on button, and the space of button or nameplate is very limited.
In addition, in case traditional button Design and Machining finishes, its information that is labeled on button or the nameplate promptly is difficult to change, and this moment, the function of each button must immobilize in order to guarantee the visualize of keyboard, and this tends to cause operating personnel's use inconvenience.For instance, our employed computer keyboard is known as qwerty keyboard now.The purpose of design of this keyboard is to reduce typing speed significantly, operator's key scroll is reduced to be unlikely to the degree of the mechanical type typewriter card key that can make for 19th century.In today that the mechanical type typewriter is eliminated already, the layout of qwerty keyboard is pernicious, and as some keyboard layouts of optimizing for typewriting such as Charles Dvorak keyboards average typing speed is doubled.But because over more than 140 year, qwerty keyboard has become tradition, so various keyboard with more outstanding keyboard layout is difficult to popular all the time.Though we can be mapped as keyboard as other types such as Charles Dvorak keyboards with each key of qwerty keyboard by software, but the letter of etching or printing can't correspondingly change on the qwerty keyboard, this just makes letter and the pointing information complete failure that marks on the keyboard, has lost intuitive and learnability.
Photochromic agent is meant that a class can produce the material of metachromatism down in the effect of light or other electromagnetic waves (as ultraviolet ray, energetic particle beam etc.), adjoins as some silver salt, metal oxide, inorganic complex, spiral shell to mutter, gather liquor-saturated or the like a series of compounds of methane cationic colorant, fulgenic acid.
Photosensitizer refers to energy is transferred to behind the absorbed radiation energy material of photochromic agent. after accepting the absorption portion energy, photochromic agent itself chemical change takes place, be decomposed into free radical or kation, thereby initiated polymerization. and photosensitizer is returned to original state after giving light trigger with NE BY ENERGY TRANSFER, its chemical property does not change.So when specific photosensitizer and photochromic agent combination, photosensitizer can change the excitation wavelength of photochromic agent.
Fluorescer is meant by invisible electromagnetic wave or electron-beam excitations such as ultraviolet rays, absorbs its energy and produces the material of visible light.Both specific fluorescer can produce visible light under the ultraviolet ray irradiation of specific wavelength.
Polarizer is meant to allow might all have light vibration on the direction in institute, and the identical natural light of amplitude is converted into the optics of polarized light.
Polaroid is the polarized light that can stop certain polarization direction, the optics that the polarized light of other polarization directions is passed through.
Summary of the invention
In order to overcome the deficiencies in the prior art, patent of the present invention provides a kind of backlight keyboard that can show different information on each button, make keyboard under different task setting, can rely on and switch different back lights, make the different information of demonstration on the keyboard cover.
The solution of patent of the present invention is that two or more different back lights are installed in keyboard, and with different optical processing materials light wave is handled on keycap.Because the light wave physical property difference that each light source produces, so to different optical processing materials, light wave can transmission, be blocked or exciting light is handled material production fluorescence, (these information patterns may be very dim originally to make different information patterns on the same keycap, perhaps close with the button background color, so be difficult to identification), can highlight, variable color under the irradiation of different back lights or send fluorescence.So when switching different situations backlight, can show different information patterns on the button.
The good effect of patent of the present invention is:
By making each button can under difference situation backlight, show different information, make each button under different situations, the input information clear and definite that shows on the keycap, with the operator that avoids keyboard confused by a large amount of information on the button or on the button nameplate (as on the mobile phone key simultaneously mark several letters are arranged, numeral and Chinese-character stroke), so that the intuitive of influence operation, ease for use, even maloperation takes place.
In addition, patent of the present invention is applied to computer keyboard after, can solve keyboard distribution immobilization, QWERTY key position distribution mode has a strong impact on the problem of input speed.Make keyboard under various modes, carry out random switching key and distribute that (setting, software mapping that can be by operating system or the mode that changes keyboard control chip are come the signal corresponding relation of each key of conversion, its specific implementation is not within this patent discussion scope) in (such as switching to Charles Dvorak keyboard distribution mode) by QWERTY key position distribution mode, also can switch the information on each button keycap thereupon.
In addition, patent of the present invention can also allow the compatible multi-national standard of a cover keyboard, and the information on the keycap can be switched under multi-lingual pattern.At this moment, just can be with the multiple input language of same keyboard compatibility.This is especially favourable for the model universalization of keyboards such as the PDA that can't change keyboard easily, notebook and fuselage integration apparatus.
