The mobile terminal of module.
Background technology
Along with the fast development of mobile intelligent terminal, user is increasing to the demand of mobile intelligent terminal,
Simultaneously to mobile intelligent terminal experience requirement more and more higher, and profile and feel be one very important
Experience index.Wherein Mobile phone screen accounting, mobile phone thickness, photographic head protrusion height be one very important
Parameter.
In display module as shown in Figure 1, region shown in dash area is viewing area, and this viewing area with
Outer physical dimension all has large effect to screen accounting, mobile phone thickness, the projecting height of photographic head.
When driving chip (IC) 103 is inconvenient to be directly bound the display floater (Panel) at display module
The when of on 101, flexible circuit board 102 need to be increased, and driving chip 103 is welded on flexible circuitry
An integral device (chip on flexible is called for short COF) is become on plate.Institute as shown in Figure 1 to Figure 4
Showing, this display module needs flexible circuit board 102 is bent turnover, owing to flexible circuit board 102 is curved
Footpath and the amplitude of tilting are relatively big by half, and the space taken is more.
As in figure 2 it is shown, the longitudinal size Y of flexible circuit board 102 is relatively big, in the vertical, with photographic head
Assembly (CCM) 104 is interfered, and as reduced by the longitudinal size of flexible circuit board, needs narrower cabling to set
Meter, high to technological requirement, the reliability of resistance to bending is relatively low, and the limited extent shortened, and differentiates at present
Rate has been difficult in longitudinal direction after reaching full HD (Full High Definition is called for short FHD) rank
On avoid photographic head module (because resolution improve after, from display floater, be drawn out to flexible circuit board
Cabling is more, so the longitudinal size of flexible circuit board can be bigger.
As shown in Figure 4, after flexible circuit board 102 bending, lateral dimension X reaches beyond display floater amplitude
2.0mm, and thickness direction size Z reaches 1.0mm beyond display floater amplitude, maximum can reach
2.0mm, also interferes with CCD camera assembly 104 on horizontal or thickness direction；Affect complete machine therefrom
The structure of equipment, for screen accounting lifting, device thickness reduces and photographic head protrudes thickness and adversely affects.
Additionally, in order to improve screen accounting, it is necessary to shorten mobile phone length, CCD camera assembly therewith move down and with
Flexible circuit board is interfered.
