Detailed Description
In order to make the objects, technical solutions and effects of the present application clearer and clearer, the present application is further described in detail below with reference to the accompanying drawings and examples.
The OLED device comprises a metal layer, and the surface of the metal layer has high light reflectivity. Therefore, the OLED display panel can reflect external environment light to a certain extent, and the display effect of the OLED display panel is influenced. The Circular Polarizer (CPL) is arranged on one side of the light-emitting surface of the OLED display panel, so that the reflection of the metal surface to the external environment light can be eliminated. However, CPL has a large thickness (about 66 μm) and is brittle, and has a high elastic modulus, which makes it difficult to apply it to a flexible OLED display panel.
For solving the higher problem of OLED display panel light reflectivity among the prior art, this application discloses a display panel includes: array substrate and filter layer. The array substrate is provided with a plurality of driving components arranged in an array manner, the filter layer comprises a shading matrix and a plurality of filter elements, the shading matrix is provided with a plurality of hollow grooves arranged in an array manner, and each filter element is positioned in one hollow groove to form a plurality of filter elements arranged in an array manner; the array arrangement density of the filter elements is greater than that of the driving assembly. As described in detail below.
Fig. 1 is a schematic structural diagram of a display panel according to an embodiment of the present application. The display panel 1 includes an array substrate 10 and a filter layer 20.
The array substrate 10 is provided with a plurality of driving assemblies 110 arranged in an array. The driving elements 110 are arranged on the substrate 120 in an array. The driving element 110 may include a Thin Film Transistor (TFT) 111. The thin film transistor 111 may refer to a semiconductor control device formed by depositing a thin film on the substrate 120.
The filter layer 20 includes a light-shielding Matrix (BM) 210 and a plurality of filter elements 220, the light-shielding Matrix 210 has a plurality of hollow-out grooves arranged in an array, and each filter element 220 is located in one hollow-out groove to form a plurality of filter elements 220 arranged in an array. The light-shielding matrix 210 is a black light-shielding layer and can function to shield light. By arranging the light-shielding matrix 210 and arranging the filter layer 20 in the interval region of the light-shielding matrix 210, the incident amount of external light can be reduced, and the surface reflectivity of the OLED display panel 1 can be further reduced. The light shielding matrix 210 and the filter element 220 have small structural thicknesses, can be bent, and can be applied to the flexible OLED display panel 1. The filter element 220 includes a filter material to achieve a filtering effect. For example, the filter material may be a Color Filter (CF). The filter element 220 has a property of allowing only light of a specific wavelength to transmit, thereby achieving a filtering effect.
The array density of the filter elements 220 is greater than the array density of the driving assembly 110. The array arrangement density is the product of the number of each row arrangement and the number of each column arrangement in a unit area. The array arrangement density may include a column arrangement density and a row arrangement density. Specifically, the row arrangement density of the filter elements 220 may be greater than the row arrangement density of the driving assembly 110, and the column arrangement density of the filter elements 220 is equal to the column arrangement density of the driving assembly 110; alternatively, the row arrangement density of the filter elements 220 may be greater than that of the driving assembly 110; alternatively, the column arrangement density and the row arrangement density of the filter elements 220 are greater than those of the driving assembly 110. When the array arrangement density of the filter elements 220 is greater than the array arrangement density of the driving elements 110, that is, the number of the filter elements 220 arranged in the front projection area of the filter layer 20 by one driving element 110 is greater than one. Accordingly, the area of light blocking matrix 210 within the orthographic projection area of filter layer 20 is increased by one driving element 110.
The array density of the filter elements 220 is set to be greater than the array density of the driving assembly 110. The increased array density of the filter elements 220 may increase the light-shielding area of the light-shielding matrix 210, reduce the incident area of external light, reduce the reflected light, and reduce the light reflectivity of the display panel 1. Meanwhile, since the array arrangement density of the filter elements 220 is greater than that of the driving assembly 110, the light shielding area can be increased without increasing the array arrangement density of the driving assembly 110. The array substrate 10 of the display panel 1 is not difficult to manufacture, and has low external light reflectivity.
In one embodiment, the array density of the filter elements 220 is at least twice the array density of the driving assembly 110. I.e. the number of filter elements 220 per unit area of the display panel 1 is at least twice the number of driving components 110. For example, the number of the filter elements 220 per row in the unit area of the display panel 1 may be at least twice as many as the number of the driving components 110, or the number of the filter elements 220 per column in the unit area of the display panel 1 may be at least twice as many as the number of the driving components 110; or the number of the filter elements 220 in each row and each column in a unit area of the display panel 1 is at least twice the number of the driving assemblies 110. Increasing the array density of the filter elements 220 to twice the array density of the driving assembly 110 can significantly increase the light-shielding area in the display panel 1, and can significantly reduce the light reflection of the display panel 1.
In one embodiment, the display panel 1 further includes a light emitting layer 30. The light-emitting layer 30 includes a plurality of light-emitting units 310 arranged in an array, and the light-emitting layer 30 is located between the array substrate 10 and the filter layer 20. The light emitting layer 30 may emit light. The array density of the light emitting units 310 is greater than or equal to the array density of the driving assembly 110. The Light Emitting unit 310 may be a Micro Light-Emitting Diode (Micro LED, which may also be referred to as u-LED), an Organic Light-Emitting Diode (OLED), or a Quantum Dot Light-Emitting Diode (QLED). For example, the light emitting cell 310 may be an OLED device including a cathode layer 311, an anode layer 312, and an organic layer 313. The light emitting layer 30 emits light in such a manner that electrons and holes are injected into the organic layer 313 from the cathode layer 311 and the anode layer 312, respectively, and are recombined in the organic layer 313 to form an excited state, and finally, the excited state attenuates to emit light. The cathode layer 311 is a metal layer, for example, the cathode layer 311 may include an Indium Tin Oxide (ITO) material and is disposed on one side of the light emitting unit 310 close to the light emitting surface.
The light emitting unit 310 may be driven by the driving component 110 to emit light, wherein the driving component 110 may further include a transparent electrode 112 and a storage capacitor 113. The thin film transistor 111 controls the light emitting unit 310 to emit light; the storage capacitor may store a signal so that the light emitting unit 310 can maintain brightness, and the transparent electrode 112 electrically connects the thin film transistor 111 and the storage capacitor 113.
The light emitting layer 30 further includes pixel defining structures 320 arranged in an array, and pixel openings between adjacent pixel defining structures 320, in which the light emitting units 310 are located. The array arrangement density of the light emitting units 310 is greater than or equal to the array arrangement density of the driving assembly 110, which may mean that the row arrangement density of the filter element 220 is greater than the row arrangement density of the driving assembly 110, and the column arrangement density of the filter element 220 is equal to the column arrangement density of the driving assembly 110; alternatively, the row arrangement density of the filter elements 220 may be greater than that of the driving assembly 110; alternatively, the column arrangement density and the row arrangement density of the filter elements 220 are greater than those of the driving assembly 110. That is, the number of the light emitting cells 310 per unit area is greater than the number of the driving elements 110, or the number of the light emitting cells 310 per unit area is equal to the number of the driving elements 110.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a display panel according to another embodiment of the present application. In one embodiment, the array density of the light emitting units 310 is greater than the array density of the driving assembly 110; each driving assembly 110 faces at least two light emitting units 310; at least part of the driving assembly 110 is connected to at least two light emitting units 310. Each driving assembly 110 is provided with two or more light emitting units 310 in the front projection area of the light emitting layer 30. Also, at least a portion of the driving assembly 110 is connected to two or more light emitting units 310 and controls to drive at least two of the light emitting units 310 connected thereto. For example, the number of the light emitting units 310 connected to each driving assembly 110 may be equal, and at least two light emitting units 310 are connected.
In one embodiment, the array density of the light emitting units 310 is equal to the array density of the filter elements 220, and the light emitting units 310 are disposed in one-to-one correspondence with the filter elements 220. That is, one filter element 220 is disposed on each light emitting unit 310.
In one embodiment, the area of the hollow-out groove is greater than or equal to the area of the light emitting unit 310. Accordingly, the area of the filter unit is equal to the area of the light emitting unit 310, or the area of the filter unit is greater than the area of the light emitting unit 310. The increase of the area of the hollow groove may increase the transmittance of the light generated by the light emitting unit 310. It should be noted that the area of the hollow-out groove is slightly larger than the area of the light emitting unit 310, and even if the area of the hollow-out groove is increased, the increase of the light shielding area of the light shielding matrix 210 is not affected.
The light emitting units 310 include a first light emitting unit 310a, a second light emitting unit 310b, and a third light emitting unit 310c that generate different colors of light, respectively. Accordingly, the filter elements 220 may include a first filter element 220a, a second filter element 220b, and a third filter element 220c capable of filtering different colors of light. The color of the filter element 220 is the same as the color of the corresponding light emitting unit 310. For example, the first light emitting unit 310a generates red light, and the first filter element 220a is a red filter; the second light emitting unit 310b generates green light, and the second filter element 220b is a green filter; the third light emitting unit 310c generates blue light, and the third filter element 220c is a blue filter.
With continued reference to fig. 2, in one embodiment, each driving element 110 faces two different light emitting units 310. That is, one driving assembly 110 includes two light emitting units 310 generating different lights in the front projection range of the light emitting layer 30. The first light emitting unit 310a, the second light emitting unit 310b and the third light emitting unit 310c are alternately arranged in sequence, for example, the arrangement may be abcabcabc. Thus, although the light-shielding area of the light-shielding matrix 210 is increased, so that the light-emitting area of the light-emitting unit 310 becomes smaller, the display effect of the display panel 1 can be made finer due to the increased number of the light-emitting units 310. The driving member 110 may be connected with one light emitting unit 310 positioned thereon and the light emitting unit 310 positioned on the other driving member 110 to generate the same color of light, and the two light emitting units 310 may be the two closest light emitting units 310 to generate the same color of light.
The light emitting unit 310 and the driving assembly 110 may have other different corresponding relationships. Referring to fig. 3, fig. 3 is a schematic structural diagram of a display panel according to another embodiment of the present application. In one embodiment, each driving assembly 110 faces two identical light emitting units 310. That is, one driving assembly 110 includes two light emitting units 310 generating the same light in the front projection range of the light emitting layer 30. The first light emitting unit 310a, the second light emitting unit 310b and the third light emitting unit 310c are alternately arranged in sequence, for example, the arrangement may be aabbcc. The driving component 110 can control and drive the two light emitting units 310 on the driving component 110, so that the connection mode between the driving component 110 and the light emitting units 310 can be simplified, and no other connecting circuit layer is required to be additionally arranged.
Referring to fig. 1, the filter elements 220 and the light emitting units 310 may not be disposed in a one-to-one correspondence. In one embodiment, the array density of the filter elements 220 is at least twice as high as the array density of the light emitting units 310. That is, two filter elements 220 are disposed on one light emitting unit 310, so that one light emitting unit 310 includes at least two filter elements 220 and at least one light shielding matrix 210 in an orthographic projection area of the filter layer 20, thereby being capable of further increasing a light shielding area of the light shielding matrix 210. In addition, the area of the light-shielding matrix 210 located in the orthographic projection area of one light-emitting unit 310 on the filter layer 20 may be equal to or smaller than the area of the light-shielding matrix 210 facing the spacing area of the light-emitting unit 310, so as to reduce the distance between two filter elements 220 located on the same light-emitting unit 310, thereby improving the display effect of the display panel 1.
In an embodiment, display panel 1 further includes an encapsulation layer 40, and encapsulation layer 40 is located between filter layer 20 and light-emitting layer 30. The encapsulation layer 40 is used to encapsulate and protect the light-emitting layer 30. The encapsulation layer 40 may include an inorganic thin film encapsulation layer (not shown) and an organic thin film encapsulation layer (not shown) that are stacked.
The application also discloses a display device, please refer to fig. 4. Fig. 4 is a schematic structural diagram of a display device according to an embodiment of the present application. The display device includes a display panel 1 and a driving chip 2. The display panel 1 is any one of the display panels 1 in the above embodiments, and the array substrate 10 is not described herein to be provided with the driving elements 110 arranged in an array. The driving chip 2 is electrically connected to the driving component 110 and is used for providing a driving signal to the driving component 110, so that the driving component 110 can control and drive the light emitting unit to emit light.
According to the display device, the density of the filter element is set to be larger than that of the drive assembly, so that the area of the shading matrix can be increased while the preparation difficulty of the drive assembly of the display panel is not increased, the incident light from the outside is reduced, and the light reflectivity of the display panel is reduced. In addition, the display device in this application has still further improved the density of luminescence unit for display panel's display effect is more exquisite.
The above description is only for the purpose of illustrating embodiments of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings of the present application or are directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
