Referring to fig. 7, fig. 7 is a partial cross-sectional view of a first display area of a display panel according to another embodiment of the present invention.
In some optional embodiments, in the display panel provided in the embodiments of the present invention, the optical fiber layer 30 may also be disposed between the light emitting device layer 20 and the array substrate 10, and when the external light irradiates the display panel, the incident light in the first display area E firstly passes through the light emitting device layer 20, then passes through the optical fiber layer 30, and then reaches the photosensitive assembly 40 through the array substrate 10.
In some alternative embodiments, when the optical fiber layer 30 is disposed between the light emitting device layer 20 and the array substrate 10, the optical fiber layer 30 may be disposed corresponding to the pixel region E1 and the light transmissive region E2, that is, the projection of the optical fiber layer 30 in the first direction Y covers the first display region E, and the optical fiber layer 30 is simple and convenient to dispose; of course, the optical fiber layer 30 may be disposed only corresponding to the light-transmitting region E2, and is also within the protection scope of the present invention.
It is understood that, since the TFT array of the array substrate 10 is electrically connected to the light emitting device layer 20 to control the light emitting device layer 20 to emit light, a gap may be preset when the optical fiber layer 30 is disposed, so that the connection line of the array substrate 10 and the light emitting device layer 20 can pass through the optical fiber layer 30.
Please refer to fig. 8 to 11; FIG. 8 is a partial cross-sectional view of a first display area of a display panel according to yet another embodiment of the present invention; FIG. 9 is a schematic diagram of light paths of external light entering the display panel shown in FIG. 8; fig. 10 is a partial cross-sectional view of a display panel according to still another embodiment of the present invention; fig. 11 is a schematic diagram of light paths when external light enters the display panel shown in fig. 10.
In some optional embodiments, the optical fiber layer 30 may be further disposed on a side of the light emitting device layer 20 away from the array substrate 10, so that incident light in the first display area E passes through the optical fiber layer 30 and then reaches the photosensitive component 40 through the light emitting device layer 20 and the array substrate 10, and the optical fiber layer 30 may earlier converge the incident light, thereby reducing scattering, reflection and diffraction of the light passing through the light emitting device layer 20, and further increasing the amount and intensity of the light incident to the photosensitive component 40.
When the optical fiber layer 30 is disposed on the side of the light emitting device layer 20 away from the array substrate 10, in some alternative embodiments, the optical fiber layer 30 may be disposed between the light emitting device layer 20 and the cover plate 50, so as to ensure that the outer surface of the display panel is flat and smooth.
Alternatively, to facilitate the arrangement of the optical fiber layer 30, the optical fiber layer 30 may also be arranged on the outer surface of the cover plate 50, i.e., the surface of the cover plate 50 on the side away from the light emitting device layer 20.
Alternatively, the optical fiber layer 30 may be embedded in the cover plate 50, which can reduce the overall thickness of the display panel.
It is understood that the optical fiber layer 30 and the cover plate 50 or the light emitting device layer 20 may be bonded by optical glue, or may be connected by electrostatic absorption or vacuum absorption, depending on the position of the optical fiber layer 30, which is not particularly limited in the present application.
In some alternative embodiments, when the optical fiber layer 30 is disposed on the side of the light emitting device layer 20 away from the array substrate 10, the optical fiber layer 30 may be disposed corresponding to the pixel region E1 and the light transmission region E2, that is, the projection of the optical fiber layer 30 in the first direction Y covers the first display region E; when the display panel is in a display state, light emitted by the light emitting device layer 20 passes through the optical fiber layer 30 and then is seen by human eyes, the light can be reduced by the optical fiber layer 30 and scattered from the side edge, the light emitting direction is uniform, and the brightness of the display panel in the first direction Y can be improved.
Of course, the optical fiber layer 30 may be disposed only corresponding to the light-transmitting region E2, so as to prevent the light of the light-emitting device layer 20 from emitting in a uniform direction after passing through the optical fiber layer 30, which affects the viewing angle, and is also within the protection scope of the present invention.
When the optical fiber layer 30 is only arranged corresponding to the light-transmitting area E2, there are various ways to prepare the optical fiber layer 30, and in some alternative embodiments, the optical fiber layer 30 may be directly integrated corresponding to the light-transmitting area E2 when the display panel is manufactured; of course, it is also within the scope of the present invention to integrate the entire optical fiber layer 30 corresponding to the entire first display area E, and then to remove the optical fiber layer 30 corresponding to the pixel area E1 by laser etching, plasma etching, or the like.
In some alternative embodiments, the thickness of the optical fiber layer 30 may be set to 0.2 μm to 200 μm, and the diameter of the optical fiber may be 0.05 μm to 100 μm.
It is understood that, in order to facilitate the fabrication of the optical fiber layer 30, the diameters of the optical fibers of the optical fiber layer 30 may be the same, which can save the cost. Of course, the diameters of the optical fibers may be different and are within the scope of the present invention.
In addition, the embodiment of the invention also provides a display device, which comprises the display panel.
In some optional embodiments, the display apparatus further includes a photosensitive element 40, and the photosensitive element 40 is disposed on a side of the array substrate 10 facing away from the light emitting device layer 20 corresponding to the first display region E.
According to the display device provided by the embodiment of the invention, the optical fiber layer 30 is at least arranged at one side of the array substrate 10 facing the light-emitting device layer 20 corresponding to the first display area E, the optical fiber layer 30 comprises a plurality of optical fibers distributed in an array manner, the long axes of the optical fibers extend along the first direction Y, when the photosensitive component 40 is used for lighting, incident light in the first display area E can firstly pass through the optical fiber layer 30 and then reach the photosensitive component 40 through the array substrate 10, the optical fiber layer 30 can change the propagation direction of the light, and the scattering, reflection and diffraction generated when the light passes through the array substrate 10 are reduced, so that the light quantity and the light intensity incident to the photosensitive component 40 can be increased, and the lighting requirement of the photosensitive component 40 is met.
Alternatively, the photosensitive assembly 40 may include a camera, an infrared sensor, or the like. When photosensitive assembly 40 is the camera, utilize optical fiber layer 30 can increase the light volume and the light intensity of incidenting the camera, and then can improve the imaging quality of camera under the screen.
The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Also, different features that are present in different embodiments may be combined to advantage. Other variations to the disclosed embodiments can be understood and effected by those skilled in the art upon studying the drawings, the specification, and the claims.
