The the first pixel-driving circuit PC1 and the second pixel-driving circuit PC2 of column provide constant high voltage signal.
With continued reference to shown in Fig. 9 and Figure 10, in order to guarantee the light transmittance of the second viewing area 21, avoid because of the second gold medal of setting
Belong to electrode plate 211d and brings the problem of reducing light transmittance.In one specific embodiment of the application, by by the second metal
Electrode plate 211d is arranged in the side that the first metal electrode board 211b deviates from the second luminescent layer 211c, and second plate 211a
It is the second metal electrode board 211d of covering.Specifically, the first metal electrode board 211b has the first area of plane S11, and second
Metal electrode board 211d has third area of plane S13.In order to guarantee the second metal electrode board 211d completely by second plate
211a covering, in the embodiment of the present application, third area of plane S13 need to be less than or are equal to the second area of plane S12.Passing through will
Second metal electrode board 211d is arranged in the lower section of the first metal electrode board 211b, and second plate 211a be it is opaque, be all-trans
Penetrate structure.It thereby may be ensured that the light transmittance for not influencing the second viewing area 21.
Embodiment of above is divided by the data line D11 and constant high voltage signal wire P11 being multiplexed in the second viewing area 21
Current potential is not provided to first capacitor structure and the second capacitance structure, the workload of the second pixel unit 211 is mended to realize
It repays, to realize the homogeneity that the first viewing area 11 and 21 picture of the second viewing area are shown.
On the basis of above embodiments, present invention also provides the realization sides of the compensating electric capacity of another second viewing area 21
Formula, specifically as shown in Figure 11~Figure 12, in this specific embodiment, and the first metallic signal lines of the display panel 1, Ke Yiwei
The constant voltage signal line of constant high voltage signal and/or constant low voltage signal is provided to the first pixel unit 111.At one
In specific embodiment, which is used to provide constant high voltage signal to the first pixel unit 111,
And and can be arranged with data line D11 same layer, formed by same metal pattern layers.
In the present embodiment, constant voltage signal line P11 is formed in order to realize the simplification that technique is made, while can be multiplexed
The 4th metal layer, by same metal layer (the 4th metal layer) patterning form constant voltage signal line P11 and the first metal
Electrode plate 211b.That is, the first metal electrode board 211b and corresponding constant voltage signal line P11 are to be connected directly
's.In the present embodiment, it by the way that one end of first capacitor structure to be connected electrically on constant fixed current potential, thereby may be ensured that
The stability of first capacitor.It should also be noted that due to including multiple second pixel units 211 in the second viewing area 21, therefore
In second viewing area 21, portion constant voltage signal line P11 is extended in the second viewing area D21 from the first viewing area D11, Xiang Wei
Constant voltage signal is provided in the first pixel-driving circuit PC1 and the second pixel-driving circuit PC2 of same row.
The embodiment of the present application also provides a kind of display devices, and as shown in figure 13, Figure 13 is provided by the embodiment of the present application
Display device structural schematic diagram, which includes above-mentioned display panel 1, wherein the specific structure of display panel 1 is
It is described in detail in the above-described embodiments, details are not described herein again.Certainly, display device shown in Figure 13 is only to illustrate
Illustrate, which, which can be, any such as mobile phone, tablet computer, laptop, electric paper book or television set has
The electronic equipment of display function.
Due to a kind of display panel provided by the embodiments of the present application and display device, by being equipped with the second of non-display hole
In viewing area, setting metal auxiliary electrode plate (the first metal electrode board) forms capacitor with the anode in corresponding second pixel unit
Structure forms the compensating electric capacity to corresponding second pixel unit.Since the second viewing area is set as high saturating in this application
Light rate region, specifically, by reducing the pixel unit number of the second viewing area, to promote the light transmission of the second viewing area
Rate.Since pixel density is smaller for the first viewing area, thus in the second viewing area the second pixel unit workload
Be less than the first viewing area, when showing same picture, then can lead to the problem of display it is inhomogenous, therefore in this application by
Compensation capacitance structure is set in the second viewing area and carrys out balance work loads.Specifically, in the auxiliary gold of the second viewing area setting
The current potential for belonging to electrode plate is provided by the metallic signal lines being located in the first viewing area, in this way can be to avoid other setting metal signal
Line reduces design cost and because additional is arranged brought by metallic signal lines, to picture in the first viewing area and the second viewing area
The adverse effect of plain unit such as generates additional parasitic capacitance, causes the problems such as showing unevenness.
The foregoing is merely the preferred embodiments of the application, not to limit the application, all essences in the application
Within mind and principle, any modification, equivalent substitution, improvement and etc. done be should be included within the scope of the application protection.
