现有技术中的显示面板是未设置光路调整结构的，由发光单元的第一发光区域出射的光线经过微透镜阵列后多以平行微透镜的光轴方向出射，而发光单元的边缘区域，即相当于本发明所述的第二发光区域出射的光线经过微透镜阵列后容易变得更加发散，显示装置的正视角出光部分被抑制，严重影响显示装置的出光效果。本发明提供的显示装置，通过设置位于发光单元上层的光路调整结构、位于光路调整结构上层的第一隔离层，第一隔离层接触并覆盖光路调整结构，以保证显示装置的显示效果。The display panel in the prior art is not provided with an optical path adjustment structure, and the light emitted from the first light-emitting area of the light-emitting unit passes through the microlens array and exits in the direction of the optical axis of the microlens, while the edge area of the light-emitting unit is The light emitted from the second light emitting area of the present invention is likely to be more divergent after passing through the microlens array, and the light emission part of the display device from the front view angle is suppressed, which seriously affects the light emission effect of the display device. The display device provided by the present invention ensures the display effect of the display device by arranging an optical path adjustment structure located on the upper layer of the light emitting unit and a first isolation layer located on the upper layer of the optical path adjustment structure, and the first isolation layer contacts and covers the optical path adjustment structure.

进一步地，第一隔离层104的的材料为无机绝缘材料，起到一定的平坦化和绝缘作用。同时第一隔离层104的折射率小于光路调整结构103的折射率，第一隔离层104的折射率一般在1.4-1.5，光路调整结构103的折射率一般在1.6-1.8，光路调整结构103和第一隔离层104的折射率不同，使得光线在经过光路调整结构103与第一隔离层104的界面处发生偏转，朝向偏离微透镜1051的光轴方向出射。Further, the material of thefirst isolation layer 104 is an inorganic insulating material, which plays a certain role of planarization and insulation. At the same time, the refractive index of thefirst isolation layer 104 is smaller than the refractive index of the opticalpath adjustment structure 103, the refractive index of thefirst isolation layer 104 is generally 1.4-1.5, the refractive index of the opticalpath adjustment structure 103 is generally 1.6-1.8, and the opticalpath adjustment structure 103 and The refractive indices of thefirst isolation layer 104 are different, so that the light is deflected at the interface between the opticalpath adjustment structure 103 and thefirst isolation layer 104 and exits in a direction deviating from the optical axis of the microlens 1051 .

同时为进一步保证对光线光路的调整效果，光路调整结构103包括靠近衬底基板101一侧的第一表面1031、远离衬底基板101一侧的第二表面1032以及连接第一表面1031和第二表面1032的侧面1033，侧面1033在衬底基板101所在平面的垂直投影覆盖第二发光区域1022在衬底基板101所在平面的垂直投影，使得第二发光区域1022出射的光线均能被光路调整结构103接收到，并合理设置侧面1033与第一表面1031之间呈一定角度的夹角，以使得光线在侧面1033与第一隔离层104的界面处根据折射率和光线入射至侧面1033的入射角度进行偏转，并出射至微透镜阵列105。At the same time, in order to further ensure the adjustment effect of the light path, the lightpath adjustment structure 103 includes afirst surface 1031 on the side close to thebase substrate 101, asecond surface 1032 on the side away from thebase substrate 101, and connecting thefirst surface 1031 and thesecond surface 1032. Theside 1033 of thesurface 1032, the vertical projection of theside 1033 on the plane where thebase substrate 101 is located covers the vertical projection of the secondlight emitting area 1022 on the plane where thebase substrate 101 is located, so that the light emitted by the secondlight emitting area 1022 can be adjusted by theoptical path structure 103 received, and reasonably set the angle between theside 1033 and thefirst surface 1031 at a certain angle, so that the light is incident on theside 1033 at the interface between theside 1033 and thefirst isolation layer 104 according to the refractive index and the incident angle of the light to theside 1033 It is deflected and emitted to the microlens array 105 .

Theside surface 1033 of thestructure 103 is flat, the refractive index of the opticalpath adjustment structure 103 is greater than the refractive index of thefirst isolation layer 104 , and the light emitted from the second light-emittingregion 1022 passes through the interface between theside surface 1033 and thefirst isolation layer 104 toward the direction away from the microlens 1051 . The direction of the optical axis is deflected, changing the optical path of the outgoing light. FIG. 6 is a schematic structural diagram of another display device according to an embodiment of the present invention. As shown in FIG. 6 , theside surface 1033 of the opticalpath adjustment structure 103 is a curved surface. The final exit direction of the light is parallel to the direction of the optical axis of the microlens 1051. At this time, theside surface 1033 can be a convex curved surface to realize the optical path adjustment of the outgoing light. The specific optical path is the same as when theside surface 1033 of the opticalpath adjustment structure 103 is a plane. Too much elaboration.

继续参考图6，可选的，侧面1033包括曲面；沿显示装置100的出光方向，曲面中的点的切平面与第一表面1031之间的夹角逐渐减小。Continuing to refer to FIG. 6 , optionally, theside surface 1033 includes a curved surface; along the light emitting direction of thedisplay device 100 , the angle between the tangent plane of the point in the curved surface and thefirst surface 1031 gradually decreases.

其中，为保证光路调整结构103的侧面1033为曲面时，对发光单元102出射的光线在侧面1033与第一隔离层104界面处的偏转效果，避免曲面的凸起程度较大，造成偏转后的光线过于发散，影响后续的出光效果，合理设置曲面的凸起程度，沿显示装置100的出光方向，曲面中的点的切平面与第一表面1031之间的夹角逐渐减小，保证光线经光路调整结构103和第一隔离层104后的偏转效果，使得光线最终均以与微透镜1051的光轴平行的方向出射，进而保证显示装置100的显示亮度。Among them, in order to ensure the deflection effect of the light emitted from the light-emittingunit 102 at the interface between theside 1033 and thefirst isolation layer 104 when theside surface 1033 of the opticalpath adjustment structure 103 is a curved surface, it is avoided that the convexity of the curved surface is relatively large, causing the deflected light.

Along the light-emitting direction of thedisplay device 100, the angle between the tangent plane of the point in the curved surface and thefirst surface 1031 gradually decreases, so as to ensure that the light passes through. The deflection effect of the opticalpath adjustment structure 103 and thefirst isolation layer 104 makes the light finally exit in a direction parallel to the optical axis of the microlens 1051 , thereby ensuring the display brightness of thedisplay device 100 .

The optical path is adjusted to deflect in the direction deviating from the optical axis of the microlens 1051 , so that the light finally exiting through thesecond isolation layer 106 exits along the optical axis parallel to the microlens 1051 , thereby improving the brightness of the light emitted by thedisplay device 100 .

In the curve shown in FIG. 15 , the distance H between the exit position point A of the light on theside 1033 and the bottom surface of the microlens is 1 μm, and the projection of the exit point A of the light on theside 1033 on thefirst surface 1031 , and theside 1033 The distances D between the intersection points with thefirst surface 1031 are 0 μm, 0.1 μm and 0.2 μm, respectively. At this time, the angle α between the tangent plane corresponding to any point of thedifferent side surfaces 1033 and thefirst surface 1031 can be obtained as It is ensured that the light emitted from the interface between the microlens 1051 and thesecond isolation layer 106 is parallel to the optical axis of the microlens 1051 , that is, when the included angle γ is 0°, the corresponding included angle α satisfies 27°≤α≤41°. In the curve shown in FIG. 16 , the distance H between the exit position of the light on theside 1033 and the bottom surface of the microlens 1051 is 2 μm, and the incident position point A of the light is the projection point of thefirst surface 1031 , and theside 1033 and thefirst surface 1031 are projected. The distances D between the intersection points of thesurfaces 1031 are respectively 0 μm, 0.1 μm, 0.2 μm, 0.3 μm and 0.4 μm. At this time, the angle α between the tangent plane corresponding to any point of thedifferent side surfaces 1033 and thefirst surface 1031 can be It is concluded that in order to ensure that the light emitted from the interface between the microlens 1051 and thesecond isolation layer 106 is parallel to the optical axis of the microlens 1051, that is, when the angle γ is 0°, the corresponding angle α satisfies 27°≤α≤41 °.
