When the user under rather dark or the situation that light source is not enough, for example: when in laboratory, Internet bar or meeting room, using notebook, tend to suffer from the problem that is difficult to literal on the identifying keyboard.Existing many methods solve this problem in conventional art.
First method is to install a reading lamp additional as light source above the screen of notebook.Solution cost although it is so is very cheap, and the vision impression is also all well and good, and still one owing to reading lamp power consumption, the stand-by time of the battery that can detract; Two must adjust the angle of light source, cause interference to avoid light directly to contact with user's sight.Come, the design of keyboard color must be with dark color as background color again, and the letter symbol on the button then must use light color, and to reach best result of use, this is its maximum constraints.
Second method is that fluorescent paint directly is coated on the keytop of keyboard, via sending fluorescence after the general light source irradiation, allows the letter symbol of user on can identifying keyboard in the not good environment of light.Though this method does not have the problem of price and keyboard Height Adjustment, it is also very easy to process.But to be identification rate variance, lightness not enough and easily by scratch, so estimate not high for its shortcoming.
Another kind method is many by the formed leaded light post of optical fiber in the positioned inside of keyboard, and with light-emitting diode as light source, the light guide effect by optical fiber illuminates whole keyboard then.Though with regard to the angle in brightness and useful life, such design helps the lifting of reliability, because keyboard itself needs punching to allow light pass through, the intensity of the keyboard that can detract like this.In addition, the whole height of keyboard also can thereby increase, and production cost also and then improves, and this is the most important reason that this solution is difficult to popularize.
(Electro-Luminescent, EL) material is used as light source to come a kind of method to be to use electroluminescence again.The benefit of this mode is power saving, more can seem bright in the dark, construction is easy, with low cost and shock-resistant.But obviously as seen such illumination Design can allow the keypad structure, and high temperature can detract life-span of electroluminescent material.In addition, also need extra circuit design to drive electroluminescence, cost is increased.And electroluminescent material is luminescence medium with phosphorus, so also have the consideration in the environmental protection.
Also having a kind of method is four corners that light-emitting diode are placed on keyboard, utilizes light guide sheet that light is evenly transmitted and comes.Such design is softer in brightness, and structure is also simple, and just keyboard also needs punching that light can be passed through, and makes keyboard intensity to be affected.And, need spend the long time to adjust in order to reach the consistency of brightness.
Last method is, all fills in a light-emitting diode in each button, is used as light source.Though can reach the effect of high brightness, the high brightness of light-emitting diode can cause bright spot.In addition, meeting of keyboard manufacturing cost thereby obvious increasing, and influence the stand-by time of battery greatly.
Though above many designs of illuminating keyboard are arranged, and still there are many shortcomings in these settling modes.Still need the more simple and convenient method that illuminates keyboard, the problem of keyboard identification when solving insufficient light.
