Keyboard device for handhold equipment capable of lighting with various areas

Abstract

The invention discloses a keyboard device shining with regional separation of a hand-held device, which enables the backlight of the keyboard to form that one part of a region shines and the other part is closed according to requirements, which enables the use of the keyboard to be more convenient and humanized, and simultaneously reduces the depletion of battery energy as much as possible. The technical proposal of the invention is that the keyboard device comprises keyboard components, which orderly and from top to down comprises that a plurality of key-presses which are arranged in different regions, key-press bracing frames which support the key-presses and simultaneously strengthen the integral strength of the key-presses, a buffer layer which increases the elasticity of the key-presses, a light conducting layer which is composed of a light conducting part and a non-light conducting part, wherein multiple groups of light-emitting components are arranged on the light conducting layer, each group of the light-emitting components is respectively corresponding to the key-press in each of different regions, thin-film switches which control the opening and the closing of switches to control the light-emitting components according to whether the key-presses are pressed down, and a circuit board, and the thin-film switches and the light-emitting components are all connected on the circuit board. The keyboard device is suitable for the field of manufacturing the keyboard of the hand-held device.

Description

technical field [0001] The invention relates to an input device, in particular to a keyboard device on a handheld device. Background technique [0002] Figure 1A It shows the key distribution of the keyboard device of traditional handheld devices (mobile phone, PDA, etc.). Number keys share the same key with some letter keys. The backlight of all the keys of the entire keyboard is turned on and off at the same time. When the backlight is on, the entire keyboard is illuminated, and when the backlight is off, the entire keyboard is dimmed. [0003] Figure 1B An exploded structure of a keyboard assembly of a conventional handheld device is shown. The keyboard device mainly includes: a keyboard assembly 50 , a light guide layer 60 , a membrane switch 70 and a circuit board 80 placed in order from top to bottom. The keyboard assembly 50 is composed of a key 500 , a key supporting frame 501 and a buffer layer 502 from top to bottom. [0004] The material of the button 500 c...
