Technical field
The utility model relates to a kind of membrane keyboard layout structure, relates in particular to a kind of mobile phone membrane keyboard layout structure.
Background technology
Mobile phone is very universal as topmost portable terminal, becomes one of main media of current communication.Along with the raising and the continuous progress in science and technology of people's living standard, the function that portable terminal is realized is more and more, as network browsing and mail, recreation, video display and MP4 broadcast etc.People are not only more and more higher to the mobile phone appearance requirement, pay close attention to the appearance of mobile phone more, and function is wished to get more and more, and size is wished more and more littler, and are therefore nowadays also just more and more with the mobile phone of membrane keyboard function.Present mobile phone on the market is most of or membrane keyboard is set to be shielded outside, the membrane keyboard negligible amounts; Be to use the LCD of band touch function, cost is higher; Membrane keyboard and LCD are set side by side at interior panel, cause the complete machine length dimension longer.
The utility model content
Problem to be solved in the utility model provides that a kind of membrane keyboard quantity is many, resistance to wear good, good hand touch, reduced complete machine cost and size and assembled mobile phone membrane keyboard layout structure easy to maintenance.
The technical scheme that the utility model adopted is: mobile phone membrane keyboard layout structure, comprise membrane keyboard FPC (flexible printed circuit board), described membrane keyboard FPC is convenient to install for stiffened, mainly pasted by modes such as glue by two-layer and above FPC and form, described membrane keyboard FPC stack is arranged on the non-display area of viewing area periphery of LCD of mobile phone display screen.
In order to make the user easy to use when night or light are more weak, also be provided with at least one LED as light source on the described membrane keyboard FPC by modes such as welding, the position of LED and quantity are determined according to position, the quantity of membrane keyboard, in order to reduce thickness, it is emitting led that described LED is preferably the top, and preferably on membrane keyboard FPC, also be pasted with one deck touch keyboard light guide sheet so that luminous evenly, the aperture that also is provided with location hole on the described touch keyboard light guide sheet and passes for LED.
In order to guarantee the sensitivity of membrane keyboard, preferred described touch key chip paster is on membrane keyboard, and in order to reduce to assemble thickness, the both sides of preferred described touch key chip and touch key solder joint office touch key FPC bending place, so that after the bending with touch key solder joint office casing inside and outside both sides, be placed on the free time place of LCD front and back after thicker like this touch chip is installed, saved the space, membrane keyboard FPC is connected conducting by connector with LCD.
Described membrane keyboard FPC makes multilayer hollow type (AIRGAP) in the bending place, does not promptly apply to bind and stay to layering and cause splendid bending effect to reach.
The outer eyeglass that is stamped on the described mobile phone membrane keyboard layout structure, preferred lens thickness is less than 1mm, to guarantee the sensitivity of membrane keyboard.
The beneficial effects of the utility model are: the utility model membrane keyboard FPC01 is pasted together by multi-layer FPC and forms, stack is arranged on the non-display area of viewing area periphery of LCD of mobile phone display screen, made full use of the clear area outside the LCD of mobile phone display screen viewing area, effectively reduced the complete machine size, and can make different shape as required, because individual layer FPC very thin (0.07mm), thereby the very thin thickness after making, can make a plurality of membrane keyboards as required, resistance to wear is good, good hand touch, the assembling process of former cell phone keyboard has been simplified in assembling and fixing easily and simple only need stick on the casing with gum and get final product, shortened the production time, improve the production production capacity, improved yield of products simultaneously, also reduced the cost and the maintenance cost of complete machine.
