Description
Technical field
The present invention relates to a kind of button (Keypad) structure, particularly a kind of method for manufacturing light guide plate.
Background technology
Press-key structure is one of main input equipment of electronic installation, each button on press-key structure has the radical of corresponding numeral, literal, phonetic symbol, input method and various functional graphic etc. usually, allow the user can import data, or carry out every function of this electronic installation.Therefore, press-key structure is a very important input equipment for electronic installation.
Because electronic installation is under well-lighted environment, the user can know the position of seeing each button, pushes Shi Buhui in operation and pushes the wrong problems such as button.If under the environment of dull thread or insufficient light, the user just is difficult to the button on the operating electronic devices.So, disposing backlight at the press-key structure internal layer, the light that this backlight produced allows the user under rayless environment, can know the position of seeing each button, also can not push the wrong button when operation is pushed.
And the employed backlight of conventional keys inside configuration is formed with light guide plate and light-emitting diode, play the time spent at electronic installation, after this light-emitting diode is lighted, this light is imported by the light guide plate front end, again by light guide plate with ray cast in each button bottom, the numeral or the figure of keytop hollow out can be shown, and the user can not push the wrong button when carrying out button operation under the dull thread environment.But when the light of light-emitting diode was directed into the rear end from the light guide plate front end, the brightness meeting of this light decayed gradually, the phenomenon that causes shown numeral in corresponding key surface, light guide plate rear end and figure will produce luminance shortage.
For solving the problem of distribution of light inequality, increased the leaded light particle one after another on light guide plate in recent years, when light imported light guide plate inside, this leaded light particle can change the conduct route of light, allowed the refraction of light-ray condensing ground on each button.Because traditional light guide plate with leaded light particle is with ink-jet technology production on making, utilize ink gun with emitted resin, be molded directly within and form the leaded light particle on the carrier, because ink gun must axially move back and forth at y, just resin can be penetrated and be sprayed on the carrier, cause production efficiency slow thus.
Another kind then is to utilize the mode of impression (imprint) to make, carry out roll extrusion with roller exactly, the protruding grain that has a plurality of formed light conductive particles on this roller surface, at roller on the flexible carrier surface or the back side during roll extrusion, can cause vector form deforming, this moment, carrier itself can be to elastic force of same direction resilience, so when the roll extrusion carrier, must according to the material of carrier how much elastic force of meeting resilience after distortion own, thereby adjust the strength that roller presses down, adjust inaccuracy if roller presses down strength, the leaded light particle that will cause completing produces defective, can't with the light-ray condensing refraction on button, cause one in the production to perplex greatly in use.
Summary of the invention
The present invention proposes the leaded light particle manufacture method on a kind of light guide plate because traditional shortcoming, and a plurality of leaded light particles of moulding on carrier easily on making make improving productivity.
For reaching above-mentioned purpose, the manufacture method of the light guide plate of button of the present invention comprises the steps:
The preparation mould has die cavity on this mould, has a plurality of blocks in described die cavity, and each block is made up of a plurality of shrinkage pool;
UV-cured resin is mixed with glass microballoon, form mixture;
Mixture is poured in the mould;
Carrier is attached on the mixture;
Utilize rolling tools on carrier surface, to roll, mixture can be filled in the mould equably, the air between mould, carrier and the mixture is discharged;
Mixture is carried out UV-irradiation, make mixture cures on this carrier, it is taken out from mould again, i.e. formation has the light guide plate of a plurality of leaded light particles.
