Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the disclosure. One skilled in the relevant art will recognize, however, that the subject matter of the present disclosure can be practiced without one or more of the specific details, or with other methods, materials, devices, etc. In other instances, well-known technical solutions have not been shown or described in detail to avoid obscuring aspects of the present disclosure.
Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted. The terms "a" and "the" are used to indicate the presence of one or more elements; the terms "comprising" and "having" are intended to be inclusive and mean that there may be additional elements other than the listed elements.
In the related art, as shown in fig. 1, in the process of attaching the flexible display substrate 8 to the cover plate 6, the flexible display substrate 8 is first attached to a carrier film 9, and then an acting force is applied to a side of the carrier film 9 opposite to the flexible display substrate 8, so that the flexible display substrate 8 is attached to the cover plate 6. First, the flexible display substrate 8 is attached to the flat area of the cover plate 6, and then the flexible display substrate 8 is attached to the curved area of the cover plate 6 by the roller 11 or the silicone gel 10. However, in the attaching process, the attaching stress applied to the portion of the flexible display substrate 8 corresponding to the bending region of the cover plate 6 is greater than the attaching stress applied to the portion of the flexible display substrate 8 corresponding to the flat region of the cover plate 6, which causes the stress received by the flexible display substrate 8 to be unbalanced, so that the flexible display substrate 8 slides relative to the cover plate 6, and further, bubbles are easily generated, thereby reducing the yield of attaching.
Further, as shown in fig. 1, the bent region of the cover 6 forms a resonant cavity. Wherein the flexible display substrate 8 comprises an anode and a cathode. The anode forms an anode reflecting surface of the resonant cavity, and the cathode forms a cathode reflecting surface of the resonant cavity. In the resonant cavity, the photon density of different energy states or different wavelengths is redistributed due to the interference of light, so that only light with specific wavelength can be emitted at a specific angle after conforming to the mode of the resonant cavity. The relationship among the microcavity length, the optical wavelength and the viewing angle of the resonant cavity is shown as the following relational expression:
λm＝2πmLeff×n×cosθ；
wherein L is the microcavity length of the resonant cavity, θifN is the sum of the phase shifts of light at the anode and cathode reflective surfacesiIs the refractive index of the organic layer, diIs the thickness of the organic layer, m is the order of the emission mode of the resonator, λ is the wavelength of the mode of order m, and θ is the angle, which is the total optical path length including the specular reflection phase shift. After the microcavity length L of the resonant cavity is determined, only light with a specific wavelength can be emitted at a specific angle, which causes the curved region of the cover plate 6 to emit light with a specific color, such as green light, and reduces the display effect.
In order to solve the problem of low yield of the attachment, the embodiment of the present disclosure provides a flexible display substrate. As shown in fig. 2 and 3, the flexible substrate may include a flexible base 1, a display layer 2, and an adhesive layer 5, wherein:
the display layer 2 is provided on one side of the flexible substrate 1. The surface of the display layer 2 facing away from the flexible substrate 1 is a light emitting surface 3. The light exit surface 3 comprises a first area 301 and a second area 302. The distance between the first region 301 and the surface of the flexible substrate 1 facing away from the display layer 2 is smaller than the distance between the second region 302 and the surface of the flexible substrate 1 facing away from the display layer 2. The adhesive layer 5 covers the first area 301 and the second area 302.
As shown in fig. 2 and 3, in the flexible display substrate according to the embodiment of the disclosure, since the distance between the first region 301 and the surface of the flexible substrate 1 facing away from the display layer 2 is smaller than the distance between the second region 302 and the surface of the flexible substrate 1 facing away from the display layer 2, and the adhesive layer 5 covers the first region 301 and the second region 302, so that the thickness of the portion of the adhesive layer 5 corresponding to the first region 301 is larger than the thickness of the portion of the adhesive layer 5 corresponding to the second region 302, in the process of attaching the flexible display substrate to the cover plate, the portion of the adhesive layer 5 corresponding to the first region 301 may be attached to the curved region of the cover plate, and the portion of the adhesive layer 5 corresponding to the second region 302 may be attached to the flat region of the cover plate, so that the adhesive force between the first region 301 and the cover plate is larger than the adhesive force between the second region 302 and the cover plate, and it may be avoided that the attachment stress applied to the portion of the flexible display substrate corresponding to the first region 301 is larger than the adhesive stress The relative sliding between the flexible display substrate and the cover plate caused by the bonding stress applied to the two regions 302 reduces the generation of bubbles and improves the yield of bonding.

The light exit surface 3 comprises a first area 301 and a second area 302. The distance between the first region 301 and the surface of the flexible substrate 1 facing away from the display layer 2 is less than the distance between the second region 302 and the surface of the flexible substrate 1 facing away from the display layer 2, that is, the thickness of the portion of the display layer 2 corresponding to the first region 301 is less than the thickness of the portion of the display layer 2 corresponding to the second region 302, that is, the surface of the light emitting surface 3 located in the first region 301 is recessed toward the flexible substrate 1 relative to the surface of the light emitting surface 3 located in the second region 302. In addition, the first region 301 and the second region 302 are connected by a slope. The included angle between the inclined surface and the first area 301 is greater than or equal to 90 ° to avoid the adhesive layer 5 from breaking at the interface between the first area 301 and the second area 302.
The orthographic projection of the light emitting surface on the flexible substrate is used as a first projection, and the orthographic projection of the first area on the flexible substrate is used as a second projection.

As shown in fig. 2 and 3, the adhesive layer 5 is used to adhere the display layer 2 to the cover plate 6. The adhesive layer 5 covers the first region 301 and the second region 302.
