Detailed Description

The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

In the description of the present invention, it should be understood that the terms "center," "lateral," "upper," "lower," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc. indicate orientations or positional relationships based on the orientation or positional relationships shown in the drawings, merely to facilitate describing the present invention and simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present invention. Furthermore, it will be understood that when an element is referred to as being "formed on" another element, it can be directly connected to the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present.

As described in the background art, when a photosensitive device such as a camera is disposed below a transparent display panel, a photograph obtained by photographing is blurred. The inventor researches and discovers that the reason for the problem is that, because the conductive wires exist in the display screen of the electronic equipment, more complex diffraction intensity distribution is caused when external light passes through the conductive wires, so that diffraction fringes appear, and normal operation of photosensitive devices such as cameras and the like can be affected. For example, when the camera below the transparent display area works, external light rays can be obviously diffracted after being routed through the lead material in the display screen, so that the picture shot by the camera is distorted.

In order to solve the above problems, an embodiment of the present application provides a display panel, which can well solve the above problems. The display panel in one embodiment comprises a substrate, a functional layer formed on the substrate, and at least one refractive index adjusting layer. The functional layer comprises at least one layer of an electrode layer, a conductive wiring layer, a pixel definition layer and a light emitting structure layer. Each functional layer comprises a plurality of functional patterns, and gaps are formed among the functional patterns. At least one of the layers has a refractive index adjustment layer located between the functional layer and the substrate or above the functional layer. The refractive index adjustment layer includes a plurality of adjustment patterns. The adjusting patterns on the same refractive index adjusting layer correspondingly adjust the refractive index difference of one functional layer. The refractive index difference is a difference between a gap between a plurality of functional patterns and a refractive index between the functional patterns on the same functional layer.

At least one refractive index adjusting layer is arranged in the display panel. Each refractive index adjusting layer comprises a plurality of adjusting patterns; the adjustment patterns on the same refractive index adjustment layer correspondingly adjust the refractive index difference of one functional layer, namely adjust the gaps among a plurality of functional patterns on the same functional layer and the refractive index difference among the functional patterns, so that diffraction effect caused by the refractive index difference of the functional layer is weakened, and further, when a camera is arranged below the display panel, the patterns obtained by photographing have higher definition.

In one embodiment, the refractive index of each refractive index adjustment layer is the same as the refractive index of the corresponding adjusted functional layer. For example, when the adjusted functional layer is an anode layer, the corresponding refractive index adjusting layer is a first adjusting layer having the same refractive index as that of the anode layer. In this case, the same refractive index means that the refractive indices are substantially the same, that is, the refractive indices within the allowable deviation range can be regarded as the same. In another embodiment, the material of each refractive index adjustment layer is the same as the refractive index of the corresponding adjusted functional layer. For example, when the adjusted functional layer is an anode layer, the corresponding refractive index adjusting layer is a first adjusting layer, and the material of the first adjusting layer is the same as that of the anode layer. In order to improve light transmittance of the display panel, both the first adjustment layer and the anode layer may be made of ITO (indium tin oxide) or indium zinc oxide (IZ 0). Furthermore, in order to reduce the resistance of each conductive trace on the basis of ensuring high light transmittance, the first adjustment layer and the anode layer can be made of materials such as aluminum doped zinc oxide, silver doped ITO or silver doped IZ 0.

In one embodiment, the thickness of each refractive index adjustment layer is the same as the thickness of the corresponding adjusted functional layer. For example, when the adjusted functional layer is an anode layer, the corresponding refractive index adjusting layer is a first adjusting layer having the same thickness as the anode layer. In other embodiments, the refractive index adjustment layer may also be made of the same material and thickness as the corresponding adjustment layer.

In the display panel in the above embodiment, when the light passes through the functional layer, the light passing through the gap area between the functional patterns of the functional layer also passes through the refractive index adjusting layer, so that the refractive index adjusting layer has the same refraction as the light in the functional pattern area, so that the paths of the external light passing through the display panel are basically the same, the refractive index difference between the gap between the functional patterns on the functional layer and the functional patterns can be weakened, the diffraction effect caused by the functional layer is weakened, and the effect of improving diffraction is achieved.

In one embodiment, the index adjustment layer is not electrically connected to other elements. Therefore, when the functional layer is made of a conductive material, it is also necessary to form an insulating layer. An insulating layer is formed between the functional layer and the refractive index adjustment layer to achieve electrical insulation between the refractive index adjustment layer and the functional layer. The thickness of the insulating layer may be set as required. In one embodiment, the thickness of the insulating layer is less than or equal to 100 nanometers.

In an embodiment, the first projection of the adjustment patterns on the same refractive index adjustment layer on the substrate surface can at least fill the gaps between the second projections of the plurality of functional patterns of the corresponding functional layers on the substrate surface. I.e. the first projection and the second projection complement each other to form a full-face pattern. The whole pattern is a complete closed pattern without gaps, namely, the projection of the adjusting pattern on the substrate can at least shade gaps between the projections of the functional pattern on the substrate so as to form the whole pattern. At this time, the adjustment patterns are complementary to each other in a region corresponding to the gap between the functional patterns when viewed from above the substrate (i.e., when the entire display panel is viewed in plan view). In the conventional display panel, there is a large refractive index deviation between functional patterns and gaps between the functional patterns on the functional layer. When the refractive index difference of different areas is large, light rays can be refracted to different degrees when passing through the functional layer, so that obvious diffraction fringes are generated. In the display panel of this embodiment, since the refractive index adjustment layer is added below the gap region between the functional patterns on the functional layer, the refractive index adjustment layer has the same refractive index as the functional layer. Therefore, when light passes through different regions of the display panel, light passing through the gap regions between the functional patterns also passes through the refractive index adjustment layer, and refraction similar to that of light in the functional pattern regions occurs in the refractive index adjustment layer. Therefore, when external light passes through the display panel, the paths are basically the same, so that the difference of refractive indexes between gaps between functional patterns on the functional layer and between functional patterns can be weakened, the diffraction effect caused by the functional layer is weakened, and the effect of improving diffraction is achieved.

Fig. 1 is a cross-sectional view of a display panel in an embodiment. In the present embodiment, the display panel includes a substrate 110, a refractive index adjustment layer 120, an insulating layer 130, and an electrode layer 140.

In an embodiment, the substrate 110 may be a rigid substrate or a flexible substrate, for example, a transparent substrate such as a glass substrate, a quartz substrate, or a plastic substrate may be selected as the rigid substrate, and a flexible PI substrate may be selected as the flexible substrate.

The refractive index adjustment layer 120 includes a plurality of adjustment patterns 120a, that is, the refractive index adjustment layer 120 does not entirely cover the substrate 110. In the present embodiment, the refractive index adjustment layer 120 is used to adjust the refractive index difference of the electrode layer 140. In one embodiment, the refractive index adjustment layer 120 and the electrode layer 140 are made of the same material, for example, ITO materials. In one embodiment, the thicknesses of the refractive index adjustment layer 120 and the electrode layer 140 are within 100 nm to 200 nm. However, the adjustment pattern 120a on the refractive index adjustment layer 120 is not electrically connected to other elements as a conductive electrode. The refractive index adjusting layer is an additional electrode layer between the substrate and the conductive electrode layer of the conventional display panel.

The thickness of the insulating layer 130 needs to ensure electrical insulation between the refractive index adjustment layer 120 and the electrode layer 140, and to ensure a certain light transmittance of the entire insulating layer while ensuring insulation. When the insulating layer 130 is too thick, the refractive path of the light is large, which is disadvantageous in achieving improvement of the diffraction effect. In this embodiment, the insulating layer 130 is thinner, so that the refractive index adjusting layer 120 and the electrode layer 140 look like on a plane as much as possible, and have a better overall effect, so as to achieve the purpose of improving the diffraction effect. Specifically, the thickness of the insulating layer 130 is less than or equal to 100 nm, and may be, for example, 10 nm, 50 nm, 80 nm, or the like. In order to improve the light transmittance of the display panel, the insulating layer material is preferably SiO ₂ ，SiN _x Al and ₂ O ₃ etc. It will be appreciated that the insulating layer 130 may also be made of other transparent insulating materials.

In an embodiment, the projection of the adjustment pattern 120a in the refractive index adjustment layer 120 on the substrate 110 is a first projection. The projection of the functional pattern 140a on the electrode layer 140 on the substrate 110 is a second projection. The first projections and the second projections are staggered with respect to each other as shown in fig. 2. At this time, from the perspective perpendicular to the substrate 110 (i.e., from the top view, the light incident direction), the adjustment patterns 120a can at least block the gaps between the patterned functional patterns 140a, so that the projection of the two patterns on the substrate 110 can form an entire pattern, as shown in fig. 2. The dashed line in fig. 2 is the edge of the first projection of adjustment pattern 120 a.

In one embodiment, the first projection and the adjacent second projection have overlapping regions. The overlap width may be 1 micron to 3 microns as shown in fig. 2. Where a represents the width of the overlap region. When there is an overlapping region between the first projection and the adjacent second projection, there is a spatial overlapping region between the adjustment pattern 120a and the functional pattern 140a in a direction perpendicular to the substrate 110, as shown in fig. 2. In this embodiment, the adjustment patterns 120a and the functional patterns 140a have the same thickness, so as to ensure that the paths of the light rays passing through the adjustment patterns are substantially uniform on the basis of the refraction of the same degree, so as to further improve the diffraction effect. The same thickness herein means that the thicknesses are substantially the same, and both can be considered to have the same thickness when the thicknesses are within the allowable deviation. In one embodiment, the thicknesses of the refractive index adjustment layer 120 and the electrode layer 140 are between 100 nm and 200 nm. For example, both thicknesses are 130 nm or 150 nm.

In the above display panel, when external light irradiates the display panel, since the complementary adjustment patterns 120a are added below the gaps between the functional patterns 140a, the light will be refracted to the same extent when passing through each position of the display panel, so as to ensure that the light paths at each position can be basically consistent, no obvious diffraction fringes can be generated, and the diffraction problem caused by the electrode layer 140 is effectively improved. In an embodiment, when the display panel is a PMOLED display panel, the electrode layer 140 may include an anode layer and a cathode layer. And the functional layer may further include at least one of a pixel definition layer and a light emitting structure layer. When the display panel is an AMOLED display panel, the electrode layer 140 includes an anode layer; the functional layer further comprises at least one of a conductive wiring layer, a pixel definition layer and a light emitting structure layer.

In one embodiment, the edge of the adjustment pattern 120a adjacent to the functional pattern 140a has a shape similar to the edge of the functional pattern 140a, see fig. 2. The display panel in fig. 2 is a PMOLED display panel, with other anodes and cathodes for driving one row/column or multiple rows/columns of subpixels. In the present embodiment, the functional pattern 140a is rectangular, that is, the side of the functional pattern is a straight line, and the adjustment pattern 120a is also rectangular with straight line sides. In other embodiments, the functional pattern 140a may also have other irregular routing structures, such as a wave, as shown in fig. 3. At this time, the adjustment pattern 120a also uses a similar side. The same broken line in fig. 3 indicates the side of the adjustment pattern 120 a. In his embodiment, when the display panel is an AMOLED display panel, a schematic diagram of the first projection and the second projection is shown in fig. 4.

In an embodiment, the display panel may be a transparent or semi-transparent and semi-reflective display panel. The transparency of the display panel can be achieved by using layers of material with a good light transmittance. For example, each layer is made of a material having a light transmittance of more than 90%, so that the light transmittance of the entire display panel can be 70% or more. Furthermore, each functional layer adopts a material with the light transmittance of more than 95%, so that the light transmittance of the display panel is further improved, and even the light transmittance of the whole display panel is more than 80%. Specifically, conductive wirings such as a cathode and an anode can be provided as ITO, IZO, ag +ITO or Ag+IZO, etc., and the insulating layer material is preferably SiO ₂ ，SiN _x Al and ₂ O ₃ and the like, the pixel defining layer 140 is made of a high transparent material.

It can be appreciated that the transparency of the display panel can also be achieved by other technical means, and the structure of the display panel can be applied. When the transparent or semi-transparent and semi-reflective display panel is in a working state, the picture can be normally displayed, and when the display panel is in other functional requirement states, external light can be irradiated to a photosensitive device and the like arranged below the display panel through the display panel.

An embodiment of the application also provides a display screen. The display screen has at least one display area. Each display area is used for displaying a dynamic or static picture. The at least one display area includes a first display area. The first display area is provided with a display panel as mentioned in any of the previous embodiments. A photosensitive device may be disposed under the first display area. Since the first display area adopts the display panel in the foregoing embodiment, when light passes through the display area, no significant diffraction effect is generated, so that the photosensitive device located below the first display area can be ensured to work normally. It can be understood that when the photosensitive device does not work, the first display area can normally perform dynamic or static image display, and when the photosensitive device works, the first display area changes along with the change of the display content of the whole display screen, for example, the external image being photographed is displayed, or the first display area can also be in a non-display state, so that the photosensitive device can further ensure that light collection can be performed normally through the display panel.

Fig. 5 is a schematic structural diagram of a display screen in an embodiment, where the display screen includes a first display area 910 and a second display area 920. It will be appreciated that the first display area 910 and the second display area 920 are not just one display area, but rather are a distinction between two types of display areas. Wherein the light transmittance of the first display region 910 is greater than the light transmittance of the second display region 920. A photosensitive device 930 may be disposed under the first display region 910. The first display area 910 is provided with a display panel as mentioned in any of the previous embodiments. The first display area 910 and the second display area 920 are each used to display a still or moving picture. Since the display panel in the foregoing embodiment is adopted for the first display area 910, no significant diffraction effect is generated when light passes through the display area, so that the light sensing device 930 located below the first display area 910 can be ensured to work normally. It can be appreciated that the first display area 910 may normally perform dynamic or static image display when the photosensitive device 930 is not in operation, and may be in a non-display state when the photosensitive device 930 is in operation, so as to ensure that the photosensitive device 930 can perform light collection normally through the display panel. In other embodiments, the light transmittance of the first display area 910 and the second display area 920 may be the same, so that the entire display panel has better light transmittance uniformity, and a better display effect of the display panel is ensured.

In an embodiment, the display panel disposed in the first display area 910 is a PMOLED display panel or an AMOLED display panel, and the display panel disposed in the second display area 920 is an AMOLED display panel, so as to form a full screen composed of the PMOLED display panel and the MOLED display panel.

The other embodiment of the application also provides a display terminal. Fig. 6 is a schematic structural diagram of a display terminal in an embodiment, which includes a device body 810 and a display screen 820. The display screen 820 is disposed on the device body 810 and is connected to the device body 810. The display 820 may be any of the display described above, and is used to display a still or dynamic image.

Fig. 7 is a schematic structural diagram of an apparatus body 810 in an embodiment. In this embodiment, the device body 810 may have a slotted region 812 and a non-slotted region 814. Photosensitive devices such as a camera 930 and a light sensor may be disposed in the slotted region 812. At this time, the display panels of the first display area of the display screen 820 are attached together corresponding to the slotted area 814, so that the above-mentioned photosensitive devices such as the camera 930 and the light sensor can collect external light through the first display area. The display panel in the first display area can effectively improve the diffraction phenomenon generated by the transmission of the external light to the first display area, so that the quality of the image shot by the camera 930 on the display device can be effectively improved, the distortion of the shot image caused by diffraction is avoided, and meanwhile, the accuracy and the sensitivity of the optical sensor for sensing the external light can be improved.

The electronic equipment can be digital equipment such as a mobile phone, a tablet, a palm computer, an ipod and the like.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
