Specific embodiment
It is of the invention to reach the technical means and efficacy that predetermined goal of the invention is taken further to illustrate, below in conjunction with
Attached drawing and preferred embodiment, to a specific embodiment of the invention, structure, feature and its effect, detailed description is as follows.
Fig. 1 is the structural schematic diagram of flexible display screen in one embodiment of the invention.As shown in Figure 1, flexibility of the invention
Display screen includes the pin configuration of substrate 11 and setting on the substrate 11, which, which includes that a plurality of arcuate line segment is connected, draws
Line 12, the connected lead 12 of arcuate line segment are used to the light-emitting component route (not shown) in viewing area 13 being connected to corresponding drive
Dynamic chip (not shown).It should be noted that arcuate line segment was connected is that index wire presents the lower structure for rising and falling and extending, and do not have to
In limit lead different zones between dipping and heaving amplitude and curvature whether uniformly continuous.
Incorporated by reference to Fig. 2, the pin configuration of flexible display screen includes patterned transparent conductive layer 121 and and patterned transparent
The pattern metal conductive layer 122 that conductive layer 121 overlaps, that is to say, that the connected lead 12 of arcuate line segment includes transparent
Conductive layer and metal conducting layer, in the present embodiment, patterned transparent conductive layer 121 are arranged on the substrate 11, pattern metal
The top of patterned transparent conductive layer 121 is arranged in conductive layer 122, and patterned transparent conductive layer 121 is ITO layer, patterned gold
Category conductive layer 122 is molybdenum aluminium molybdenum (MOALMO) complex metal layer.
Since the bending resistance of pattern metal conductive layer 122 is poor, alternating bending deformation after be easy to appear fracture,
It wears and fails, and then lead to flexible display screen damage or reduced performance, and in the knot that lead design camber line segment is connected
After structure, deflection of the connected lead 12 of arcuate line segment in axial tension or bending is Δ L=L2-L1, wherein L1 is initial
Length, L2 is stretching or length after bending, at this point, the strain for the lead 12 that arcuate line segment is connected is ε=Δ L/L1, according to recklessly
Gram law, when stress is lower than the proportional limit of material, stress and strain is directly proportional, i.e. stress σ=E ε, and E is elasticity modulus, by
It is smaller than the bending strain that linear lead design generates in the lead design that arcuate line segment is connected, thus bending stress also becomes smaller,
Namely the bending stress that pattern metal conductive layer 122 is subject to reduces.Simultaneously as material be distributed it is remoter from neutral axis,
Bending strength is higher, but also the lead design bending strength with higher that arcuate line segment is connected.In this way, by lead design at
Can avoid after the connected structure of arcuate line segment lead (the especially metal part of lead) when flexible display screen is bent by
Big stress improves the bending resistance of lead.
