Description
Technical Field
The present invention relates to the field of display, and in particular, to a display panel and a display device.
Background
With the development of display technology and the popularization of electronic products, people have increasingly high requirements on the functionality of display panels. Among them, an organic light-Emitting display panel (OLED) with a touch function is widely used because of its advantages of convenience in use, lightness, thinness, high precision, high sensitivity, and the like.
In the conventional technology, a circular polarizer is often used to eliminate the reflection of the cathode surface to the external ambient light, and improve the contrast of the OLED product under strong light. However, the circular polarizer has the disadvantages of low transmittance and low power consumption of the module, so the conventional circular polarizer is replaced by a scheme of forming a Filter layer by combining a Color Filter (CF) and a Black Matrix light shielding layer (BM). The BM and the CF are generally disposed on the same layer on the package layer, but the position relationship between the touch structure and the filter layer needs to be considered when manufacturing the display panel. If the touch structure is arranged on the filter layer, the reflectivity is high, and if the touch structure is arranged between the packaging layer and the filter layer, the light-emitting visual angle is small.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
It will be understood that when an element is referred to as being "disposed on" another element, it can be directly on 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. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Fig. 1 is a schematic plan view of a display panel according to an embodiment of the present application, and fig. 2 is a schematic cross-sectional view of the display panel in fig. 1 along line a-a'. Referring to fig. 2, an embodiment of the present disclosure provides a display panel 100, which includes a substrate 110 and a light emitting layer 120 disposed on the substrate 110. As shown in fig. 1, the light emitting layer 120 includes light emitting units 121 arranged in an array. The light emitting unit 121 may include a red light emitting unit, a green light emitting unit, and a blue light emitting unit. Adjacent light emitting units 121 are spaced apart from each other by a pixel defining layer 122.
The encapsulation layer 130 is disposed on the light emitting layer 120 for isolating water and oxygen to protect the light emitting unit 121. The encapsulation layer 130 is further provided with a touch structure 140 and a filtering unit 150. The touch structure 140 includes a first metal layer 141, an insulating layer 142, and a second metal layer 143. The first metal layer 141 may include a bridge, and the second metal layer 142 may include touch driving electrodes arranged along a first direction and touch sensing electrodes arranged along a second direction, where the first direction is perpendicular to the second direction. At the crossing position of the touch driving electrodes and the touch sensing electrodes, in order to prevent the touch driving electrodes and the touch sensing electrodes from being short-circuited, the adjacent touch driving electrodes are disconnected at the crossing position and are connected with a bridge through via holes formed in the insulating layer 142, that is, the bridge is used for communicating the two adjacent touch sensing electrodes. In order not to affect the light emission of the display panel, the orthographic projections of the first metal layer 141 and the second metal layer 143 on the package layer 130 and the orthographic projection of the light emitting unit 121 on the package 130 do not overlap with each other, that is, the first metal layer 141 and the second metal layer 143 are disposed on the package layer 130 corresponding to the gap between the light emitting units 121. Each of the filter units 150 is adjacent to the touch driving electrode and the touch sensing electrode, and an orthogonal projection of the filter unit 150 on the encapsulation layer 130 overlaps an orthogonal projection of the light emitting unit 121 on the encapsulation layer 130. The display panel further includes a light shielding layer 160, the light shielding layer 160 is disposed on the second metal layer 143, and the light shielding layer 160 can shield incident light, so as to prevent the first metal layer 141 and the second metal layer 143 from reflecting the incident light, thereby improving the display effect.
In the display panel provided by the above embodiment, the touch structure 140 and the filtering unit 150 are disposed on the packaging layer 130 at the same time, so that compared with a scheme in which the filtering unit 150 is disposed on the touch structure 140, a distance between the filtering unit 150 and the light emitting unit 121 is reduced, and a light emitting viewing angle can be increased. The light shielding layer 160 is disposed on the second metal layer 143 of the touch structure 140, and the light shielding layer 160 can shield incident light, so as to prevent the first metal layer 141 and the second metal layer 143 from reflecting the incident light, reduce the reflectivity, and improve the display effect.
In the conventional technology, when the touch layer is prepared first and then the filtering units and the shading layer are prepared on the touch layer, a transparent optical adhesive layer is deposited to protect the second metal layer after the second metal layer of the touch layer is prepared, and then the filtering units and the shading layer located between the filtering units are formed on the transparent optical adhesive layer. Because the light-shielding layer includes the black material, and the light-shielding layer directly forms on transparent optics glue film, consequently, the material of light-shielding layer can partially diffuse to transparent optics glue film when forming the light-shielding layer, leads to having partial black material on the transparent optics glue film that the luminescence unit corresponds, appears showing inhomogeneous problem.
In view of the above problem, as shown in fig. 2, according to the present invention, after the second metal layer 143 is formed, the light shielding layer 160 is formed on the second metal layer 143, then the light shielding layer 160 is etched to form a groove, and the groove is filled with the color-resistant material to form the filter unit 150, and the filter unit 150 covers the surface of the light shielding layer 160. Then, an insulating protection layer 170 is formed on the surface of the filtering unit 150, and in order to ensure light transmission, the insulating protection layer 170 is a transparent optical adhesive in this embodiment. Therefore, the light shielding layer 160 is formed first, then the color resistance material is deposited to form the light filtering unit 150, and the color resistance material is also deposited on the surface of the light shielding layer 160 during deposition to isolate the light shielding layer 160 from the insulating protection layer 170, so that the material of the light shielding layer 160 is prevented from being diffused to the insulating protection layer 170, and the display effect is improved. In this embodiment, when the light-shielding layer 160 is etched to form the groove, the etching may be stopped on the insulating layer 142, and the color-resisting material is deposited on the insulating layer 142 to form the filtering unit 150. In another embodiment, an etching stop layer is further disposed between the insulating layer 142 and the encapsulation layer 130 for protecting the encapsulation layer 130 when the metal layer is etched to form the touch electrode. When the light-shielding layer 160 is etched to form the groove, the light-shielding layer 160 may be etched continuously, the insulating layer 142 may be etched to expose the surface of the etching stop layer, and the color-resistant material may be deposited on the etching stop layer to form the filtering unit 150, so as to reduce the distance between the filtering unit 150 and the light-emitting unit 121 and increase the light-emitting viewing angle.
In one embodiment, in order to reduce the step difference of the filtering unit 150, the filtering unit 150 may be prepared first, and then the light shielding layer 160 is prepared, the light shielding layer 160 covers a part of the surface of the filtering unit 150 and at least a part of the surface of the second metal layer 143, so that the filtering unit 150 does not need to climb to the surface of the light shielding layer 160, the climbing height of the filtering unit 150 is reduced, that is, the step difference of the filtering unit 150 is reduced, and the filtering unit 150 is prevented from being broken due to the large step difference.
Specifically, as shown in fig. 3, after the touch structure 140 is formed, a color-resistant material is deposited on the insulating layer 142 to form a filtering unit 150. The filtering unit 150 is adjacent to the second metal layer 143 and disposed in a grid formed by intersecting the touch driving electrodes and the touch sensing electrodes. Around the first metal layer 141, the light filtering unit 150 adjacent to the first metal layer 141 partially covers the surface of the second metal layer 143, that is, the overlapping area of the light filtering unit 150 and the second metal layer 143 at the position corresponding to the first metal layer 141 is greater than 0, and the light shielding layer 160 covers the exposed surface of the second metal layer 143 and a part of the surface of the light filtering unit 150. It can be understood that the forward projection of the light shielding layer 160 on the encapsulation layer 130 overlaps the forward projection of the pixel defining layer 122, that is, the light shielding layer 160 only covers the portion of the filter unit 150 extending to the surface of the second metal layer 143, so as to prevent the light emitting angle from being affected.
In the above embodiment, the square resistance of the material of the light-shielding layer 160 is greater than or equal to 10^8 Ω/□. Since the light shielding layer 160 directly contacts the second metal layer 143, the resistance of the light shielding layer 160 is increased, so that the conductive capability of the light shielding layer 160 is reduced, the second metal layer 143 is protected, and the second metal layer 143 is prevented from being short-circuited with the light shielding layer 160.
In the display panel provided by the above embodiment, the filtering unit 150 is formed first, and then the light shielding layer 160 is formed, and the light shielding layer 160 covers a part of the green light unit, so that the step difference of the filtering unit 150 can be reduced. In addition, the touch structure 140 and the filter unit 150 are disposed on the package layer 130, so that compared with a scheme in which the filter unit 150 is disposed on the touch structure 140, a distance between the filter unit 150 and the light emitting unit 121 is reduced, and a light emitting viewing angle can be increased. The light-shielding layer 160 is disposed on the second metal layer 143 of the touch structure 140, and the light-shielding layer 160 can shield incident light, so as to prevent the metal on the touch layer from reflecting the incident light, reduce the reflectivity, and improve the display effect.
In another embodiment, as shown in fig. 4, after the touch structure 140 is formed, a color-resistant material is deposited on the insulating layer 142 to form the filtering unit 150. The filter unit 150 around the first metal layer 141 is adjacent to the second metal layer 143 and does not overlap the second metal layer 143. The light shielding layer 160 completely covers the surface of the second metal layer 143 and a portion of the surface of the filter unit 150. The height of the filter unit 150 may be less than the height of the second metal layer 143, so that the step difference of the filter unit 150 may be reduced, and the risk of breaking the filter unit 150 may be reduced.
In the above embodiment, when forming the touch structure 140, the first metal layer 141 is deposited first, and the first metal layer 141 is etched to form a bridge. An insulating layer 142 is deposited on the first metal layer 141, wherein the insulating layer 142 may be a transparent optical glue. And etching the insulating layer 142 to form a via hole, then depositing the second metal layer 143, and etching the second metal layer 143 to form a touch driving electrode and a touch sensing electrode. The touch sensing electrode is connected to the bridge through the via hole on the insulating layer 142. A color-resist material may then be deposited on the insulating layer 142 to form the filtering unit 150.
Further, before forming the touch structure 140, in order to ensure that the subsequent etching process does not affect the encapsulation layer 130, an etching protection layer may be formed on the encapsulation layer 130, and then the touch structure 140 may be formed on the etching protection layer. Next, when forming the filtering unit 150, the insulating layer 142 may be etched to expose the etching protection layer below, and then the color-resistant material is deposited on the etching protection layer to form the filtering unit 150, so as to shorten the distance between the remaining light emitting units 121 of the filtering unit 150 and improve the light transmittance.
In the above embodiment, the insulating layer 142 may be made of an organic material, which has high flexibility and strong bending resistance, and the insulating layer 142 is made of an organic material, so that the problem of touch failure caused by the breakage of the insulating layer 142 and stress transmitted to the touch electrode when the display panel is bent can be prevented.
Another embodiment of the present application provides a display device, including the foregoing display panel. The display device can be an electronic product such as a portable computer, a mobile phone, a flat panel, a television and the like. Compared with the scheme that the light filtering unit is arranged on the touch structure, the distance between the light filtering unit and the light emitting unit is reduced, and the light emitting visual angle can be increased. The shading layer is arranged on the second metal layer of the touch structure and can shade incident light, so that the metal on the touch layer is prevented from reflecting the incident light, the reflectivity is reduced, and the display effect is improved.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
