Description
Technical field
The present invention relates to touch control devices, touch sense group more particularly to the backlight of a kind of touch control device and the touch control device
Part.
Background technique
The touch screen of Oncell is the upper layer glass table for being formed in the screen for display for incuding the ITO layer touched
Therefore face is usually limited to the display area of display screen using touch screen its touching induction region of oncell technology production
It is interior, namely the operation only carried out in the display area of display screen can just be sensed.This carrys out the operation in display screen
Say what can't there are problems that.
However, generally also 3~4 common non-physical can be arranged in the position below mobile phone screen in traditional smart phone
Function key, be also to be operated using touch sensible.At this point, the conduct for the display screen using the production of oncell technology
For the smart phone of the display portion of entire smart phone, the touch induction circuit of the function key of its underpart will additionally be set
It sets.
Fig. 1 a is please referred to, is the front view of mobile phone namely the front view of hand-set lid 80.It is aobvious that hand-set lid 80, which divides,
Show region 801 and 3 function key patterns 802 positioned at 801 lower section of display area.With reference to Fig. 1 c, display screen 70 is located at display
Region 801 is simultaneously bonded with the back side of hand-set lid 80.
