Face bright intensity can excite the first transmitance regulating course 40 and the second transmitance regulating course 50 to control the sending of organic luminous layer 32
Light, to adjust the light penetration of transmission region, and then the optical contrast ratio of display area and transmission region can be improved.
It should be noted that in the present embodiment, the first transmitance regulating course 40 and the second transmitance regulating course 50 are having
Change its transmitance to light under the excitation for the light that machine luminescent layer 32 issues, this change is reversible, when the first transmission
When the excitation for the light that rate regulating course 40 and the second transmitance regulating course 50 are not issued by organic luminous layer 32, it is original to restore its
Light penetration, to guarantee the transparence display effect of display panel.
Wherein, in the present embodiment, the size to display area and transmission region and the size of proportion etc. have no
Other are required, and can be realized its function, specifically, the size and proportion of display area and transmission region can be according to realities
The display demand on border carries out selection setting.
Wherein, in the present embodiment, to the first transmitance regulating course 40, the second transmitance regulating course 50 and organic luminous layer
32 composition material and thickness size etc. have no other requirements, and the light issued in organic luminous layer 32 can excite the first transmission
Rate regulating course 40 and the second transmitance regulating course 50 adjust the light penetration of transmission region.
In the present embodiment, setting between the specific structure to array substrate 20 and color membrane substrates 10 and included component
The relationship of setting has no other requirements, can be realized its function, specifically, in the present embodiment, as shown in Figure 1, the coloured silk film base
Plate 10 include substrate 11, and on the position that the substrate 11 is located at display area be equipped with colored filter 12 and be used for will be colored
The black matrix 13 that optical filter 12 separates.The array substrate 20 includes substrate 21, which, which is located on the position of display area, sets
There is thin film transistor (TFT) 22.
A kind of display panel provided in an embodiment of the present invention, by being set in side of the organic luminous layer 32 towards light direction
