Spring is touched, is flexible flexible structure due to touching film, even if applying the guidance panel in curved surface, good realization touches thin
Film and the tight fit of guidance panel, have been effectively ensured the contact area of touch key-press, and film is touched with operation so as to reduce
The assembly difficulty of panel, improves the sensitivity of touch key-press, and all electronic components are installed on one piece of circuit board, are had
Effect reduces the material cost of circuit.
One example of the utility model is that display film is posted in the upper surface for touching film, and key legend is arranged on aobvious
Show on film；Or the lower surface of touch film posts display film, key legend is arranged on display film.Key legend both can be direct
The surface for touching film is arranged on, makes key legend integrated with film is touched, be favorably improved efficiency of assembling；Can also pass through
Display film is set on the surface for touching film, key legend is set on display film, make key legend and touch film split, just
Parts are changed in changing.
One example of the utility model is that the processor includes that program logic chip, touch key-press chip and display are driven
Dynamic chip, program logic chip is electrically connected by touch key-press chip with the electrode touched in film, and program logic chip passes through
Display driver chip is electrically connected with LED.
One example of the utility model is that it also includes outer cover and is arranged on the support of circuit board bottom, touch film,
Display screen and circuit board, support are arranged in outer cover, and the through hole for exposing display screen is covered with outward, are set between support and outer cover bottom wall
There is spring.The setting of spring helps to ensure that the tight fit of touch-screen and guidance panel.
One example of the utility model is that the support, outer cover bottom wall are respectively equipped with stent strut, outer cover post, and spring is placed on
On stent strut, and the end of stent strut is inserted in outer cover post.
Any of the above example, both can be separately as one embodiment, it is also possible under the premise of guarantee is reconcilable, respectively show
Example any combination constitutes combined type embodiment.
