Description

The back lighting device of keyboard

Technical field

The utility model is to provide a kind of back lighting device of keyboard, espespecially one-body molded anti-dazzling screen and reflector plate, can facilitate the back lighting device of poststack moulding application, one-body molded a slice or the reflector plate more than a slice of being provided with of at least one side in anti-dazzling screen, be folded to anti-dazzling screen one side surface for a slice or reflector plate more than a slice, and in the coated optical waveguide layer of inner accommodation space, reach the object of carrying out fast assembling operation, reducing assembly error.

Background technology

Along with the development of Technology Times, various electronics, electric product is also generally applied in people's life or operational environment, no matter and the application of desktop computer or notebook computer etc., bring especially people life and work on convenient, every various word processing, the editing and processing of photo or figure, bulletin, the application of Email or internet etc., it is all the pattern that people often use, also make the application of computer product more universal, and in the time carrying out various electronic homework by computer, all must required data be inputted one by one by keyboard, the data of inputting according to keyboard for main frame is processed, keyboard also becomes the instrument of computer operation indispensability, and at computer and various periphery product all towards gently, thin, short, little design concept is made, use function also to be promoted, especially the design of notebook computer, also by overall thickness reduction, the thickness of screen and keyboard is also reduced to amount, relatively also make keyboard by early stage large-scale framework, change the pattern of slim card into, and in keyboard, luminous element being set can be for periphery or the keyboard transmitted ray by keyboard, during for keyboard applications, can know the position of distinguishing each button, and keyboard structure is sequentially to assemble light shield layer in multiple buttons bottom, optical waveguide layer and reflector layer etc., utilization is positioned on the circuit board of optical waveguide layer multiple luminous element projection sources is set, upwards reflect through light shield layer and cover local location by reflector layer, can assemble and upwards project towards each keyboard bottom position for light source, can appear light in surface of keyboard or periphery, and at present in the optical waveguide layer of keyboard, flexible circuit board is outside must separate machined processing be coated reflector, after light shield layer, again in the multiple buttons of light shield layer top assembling, but because optical waveguide layer outside processes respectively assembling reflector and light shield layer, increase the activity duration of manufacture except must separately manufacturing moulding, improve manufacturing cost, and while carrying out assembling operation, the necessary accurate contraposition of reflector and light shield layer is on two surfaces of optical waveguide layer, also the degree of difficulty of contraposition while increasing topping-off operation, degree of error also improves, often must carry out the contraposition assembling of repetition, laminating contraposition just can complete assembling processing, and cause operation quite consuming time, take a lot of work, increase on foot staff's puzzlement and inconvenience, and carry out in order to facilitate the assembling of reflector and light shield layer to process operation, and reflector and light shield layer are to be coated on optical waveguide layer outside, also be coated flexible circuit board simultaneously, the coated meeting of storehouse shape causes the product thickness after assembling to increase on the contrary, be unfavorable on the contrary reducing of keyboard thickness.

Be with, while how solving the outside two surface-assembled reflector of optical waveguide layer, the light shield layer operation of keyboard, high, the consuming time problem of taking a lot of work of contraposition difficulty and the puzzlement of reflector and light shield layer, and the disappearance that the thickness of reflector and light shield layer also can not effectively reduce and trouble, be the relevant manufacturer that is engaged in the industry and desire most ardently the direction place that research improves.
