Example 1

As shown in fig. 1 to 8, a display panel is disclosed in the first embodiment.

In some embodiments, the display panel may be a liquid crystal display panel or an OLED (organic light emitting diode) display panel.

For example, as shown in fig. 1 to 3, if the display panel is a liquid crystal display panel, the liquid crystal display panel includes a first substrate 10, a second substrate 20, and a liquid crystal layer between the second substrate 20 and the first substrate 10, wherein the liquid crystal layer is composed of a plurality of liquid crystal molecules 30. Meanwhile, a plurality of thin film transistors (not shown) are disposed on the second substrate 20 to serve as the driving circuit layer 40, and the second substrate 20 and the first substrate 10 are fixedly connected by a frame sealant (not shown), and a plurality of liquid crystal molecules 30 are sealed between the second substrate 20 and the first substrate 10.

If the display panel is an OLED (organic light emitting diode) display panel, the OLED (organic light emitting diode) display panel includes a second substrate 20, a first substrate 10, and a pixel defining layer (not shown) and a packaging layer (not shown) disposed between the second substrate 20 and the first substrate 10, wherein the pixel defining layer is provided with a plurality of pixel openings, and each pixel opening is provided with an organic light emitting diode (not shown); the packaging layer is arranged on the pixel defining layer and covers each organic light emitting diode.

In some embodiments, as shown in fig. 1 to 3, the display panel further includes a color film layer 11 disposed between the second substrate 20 and the first substrate 10.

It should be understood that whether the display panel is a liquid crystal display panel or an OLED (organic light emitting diode) display panel. The structure and the working distance of the color film layer 11 can be the same.

In this embodiment, as shown in fig. 1 to 3, the display panel is a liquid crystal display panel, the color film layer 11 is disposed on the first substrate 10, and the surface of the color film layer 11 away from the first substrate 10 is a horizontal plane, so as to facilitate forming a subsequent film layer on the color film layer 11.

Of course, in other embodiments, when the display panel is a liquid crystal display panel, the color film layer 11 may be disposed on the second substrate 20.

It should be understood that, as shown in fig. 3, when the color film layer 11 may also be disposed on the second substrate 20, the display panel may be a display panel with a COA pixel structure, that is, after sequentially forming the driving layer 40 composed of the thin film transistors on the second substrate 20, the planarization layer 60 is formed immediately above the driving layer 40, and then the color film layer 11 is formed on a side of the planarization layer 60 away from the second substrate 20. Alternatively, as shown in fig. 2, when the color film layer 11 may also be disposed on the second substrate 20, the display panel may be a display panel with an AOC pixel structure, that is, the color film layer 11 is formed on the second substrate 20, then the driving layer 40 formed by the thin film transistor is formed on the color film layer 11, and finally the transparent conductive layer 50 formed by the ITO (indium tin oxide) material is formed on the side of the first substrate 10 facing the second substrate 20.

In this embodiment, as shown in fig. 1 to 5, the color film layer 11 includes a plurality of light shielding units 12 and a plurality of color blocking units 13, and one light shielding unit 12 is disposed between two adjacent color blocking units 13.

It should be understood that the adjacent two-color resist units 13 are formed of photoresists of different colors. Each three color resist units 13 of the plurality of color resist units 13 form a pixel group, and the three color resist units 13 forming the pixel group are respectively formed by three colors of photoresists of RGB (red green blue) in one-to-one correspondence.

Further, as shown in conjunction with fig. 6 to 8, the light shielding unit 12 includes a light shielding main body 12a and a reflecting portion 122. For example, the light shielding body 12a may also be referred to as a BM layer (black matrix layer); the light shielding body 12a may be formed by mixing several kinds of photoresists of different colors, or may be formed of a material such as metal.

In the present embodiment, as shown in fig. 6 to 8, the reflection part 122 includes at least the reflection layer 1221, and the reflection layer 1221 is disposed between the light shielding body 12a and the color resist unit 13. The surface of the reflective layer 1221 facing the color resist unit 13 is a reflective side peripheral surface 122a.

For example, as shown in connection with fig. 4 to 8, in two adjacent color resist units 13: the reflective layer 1221 surrounds the gaps between the adjacent two color resist units 13 and the light shielding body 12a. The reflective layer 1221 may be provided so as to wrap around the entire side peripheral surface of the light shielding body 12a. Of course, the light shielding body 12a may be partially wrapped around its side peripheral surface.

It should be understood that the side peripheral surface of the light shielding main body 12a is the entire surface located between the adjacent two color resist units 13.

As shown in fig. 6 and 8, the light shielding body 12a includes a first light shielding portion 121 and a second light shielding portion 123 that are disposed opposite to each other. The second light shielding portion 123 is disposed closer to the light incident side of the color film layer 11 than the first light shielding portion 121. The first light shielding portion 121 is in contact with each of the adjacent color resist units 13, so as to prevent crosstalk of light passing through the adjacent color resist units 13.

It should be understood that after the first light shielding portion 121 contacts with the adjacent color resist units 13, there is no gap between the first light shielding portion 121 and the adjacent color resist units 13, that is, after the light enters from the light incident side of the color film layer 11, part of the light except for the light passing through the color resist units 13 passes through the gap between the second light shielding portion 123 and the adjacent color resist units 13, and is blocked by the first light shielding portion 121, so that the light can only pass through the color film layer 11 from the color resist units 13.

In the present embodiment, as shown in fig. 7 and 8, the reflective layer 1221 is disposed between the second light shielding portion 123 and the color resist unit 13.

For example, the reflective layer 1221 may be provided to cover the entire side surface of the second light shielding portion 123, or may be provided only on the side surface of the second light shielding portion 123 disposed opposite to the color blocking unit 13, or may be provided to cover the entire surface of the second light shielding portion 123.

It should be understood that the surfaces of the second light shielding portions 123 disposed opposite to the adjacent color resist units 13 are all the side peripheral surfaces of the second light shielding portions 123.

Further, the orthographic projections of the reflective layer 1221 and the second light shielding portion 123 on the first substrate 10 are both located within the orthographic projection of the first light shielding portion 121 on the first substrate 10.

For example, the area of the orthographic projection of the second light shielding portion 123 on the first substrate 10 may be smaller than the orthographic projection of the first light shielding portion 121 on the first substrate 10, and the orthographic projection of the second light shielding portion 123 on the first substrate 10 is disposed corresponding to the middle area of the orthographic projection of the first light shielding portion 121 on the first substrate 10. At this time, the first light shielding portion 121 and the second light shielding portion 123 form a light shielding body 12a in a "convex" shape. And the reflective layer 1221 is provided around the side peripheral surface of the second light shielding portion 123; and the front projection of the reflective layer 1221 on the first substrate 10 is disposed corresponding to the front projection edge region of the first light shielding part 121 on the first substrate 10, and fills the front projection edge region of the first light shielding part 121 on the first substrate 10, so that the total area of the front projection of the second light shielding part 123 and the reflective layer 1221 on the first substrate 10 is equal to the front projection area of the first light shielding part 121 on the first substrate 10.

It should be understood that, since the front projections of the reflective layer 1221 and the second light shielding portion 123 on the first substrate 10 are both located in the front projection of the first light shielding portion 121 on the first substrate 10, the gap between the adjacent two color resist units 13 for setting the first light shielding portion 121 is enough to set the reflective portion 122 and the second light shielding portion 123, and no additional increase of the interval between the adjacent two color resist units 13 is required to set the reflective portion 122.

In this embodiment, the second light shielding portion 123 and the first light shielding portion 121 are integrally formed, and the materials used for the second light shielding portion and the first light shielding portion may be the same, so that the same photomask is manufactured, and the cost is reduced.

As shown in fig. 8, the second light shielding portion 123 includes a bottom surface 1231 and a top surface 1233 disposed opposite to each other, and an inclined side circumferential surface 1232 connected between the top surface 1233 and the bottom surface 1231, wherein the top surface 1233 and the bottom surface 1231 are parallel to each other. The top surface 1233 of the second light shielding portion 123 is connected to the first light shielding portion 121; the inclined side circumferential surface 1232 of the second light shielding portion 123 is connected between the bottom surface 1231 of the second light shielding portion 123 and the top surface 1233 of the second light shielding portion 123 in an inclined manner.

Of course, in other embodiments, the second light shielding portion 123 may also include a bottom surface 1231, a top surface 1233, and vertical side surfaces; the top surface 1233 of the second light shielding portion 123 is connected to the first light shielding portion 121; the vertical side surface of the second light shielding portion 123 is vertically connected between the bottom surface 1231 of the second light shielding portion 123 and the top surface 1233 of the second light shielding portion 123.

In the present embodiment, as shown in fig. 8, the reflective layer 1221 is provided on the inclined side circumferential surface 1232. For example, the reflective layer 1221 of the reflective portion 122 may be formed by coating a layer of reflective material on the second light shielding portion 123. The reflection side peripheral surface 122a is parallel to the inclined side peripheral surface 1232 of the second light shielding portion 123.

Alternatively, the reflective layer 1221 is formed by plating silver or vacuum plating aluminum on the second light shielding portion 123.

Further, the inclined side peripheral surface 1232 of the second light shielding portion 123 may be polished to be flat so as to make the reflection side peripheral surface 122a of the reflection layer 1221 connected thereto a flat surface.

Of course, the second light shielding portion 123 may have a truncated cone or a conical structure, and in this case, the inclined side circumferential surface 1232 of the second light shielding portion 123 may be curved and may be a truncated cone or a side surface of the conical second light shielding portion 123.

Referring to fig. 8, an inclined angle α is formed between the inclined side circumferential surface 1232 and the top surface 1233, where α satisfies the relationship: alpha is more than or equal to 45 degrees and less than 90 degrees.

Alternatively, α=45 °, α=49 °, α=52 °, α=57 °, α=60 °, α=64 °, α=68 °, α=74 °, α=79 °, α=81 °, α=84 °, α=86 °, or α=87°.

In the present embodiment, as shown in fig. 8, the area of the orthographic projection of the top surface 1233 of the second light shielding portion 123 on the first substrate 10 is larger than the area of the orthographic projection of the bottom surface 1231 of the second light shielding portion 123 on the first substrate 10. Of course, in other embodiments, if the process difficulty is not considered, the area of the orthographic projection of the top surface 1233 of the second light shielding portion 123 on the first substrate 10 may be smaller than the area of the orthographic projection of the bottom surface 1231 of the second light shielding portion 123 on the first substrate 10.

As shown in fig. 1 to 8, the front projection of the top surface 1233 of the second light shielding portion 123 on the first substrate 10 and the front projection of the first light shielding portion 121 on the first substrate 10 are completely overlapped, so that no step is formed between the inclined side circumferential surface 1232 of the second light shielding portion 123 and the first light shielding portion 121, and the area of the inclined side circumferential surface 1232 is further increased, so that the reflective layer 1221 is disposed in a larger area, and the reflective area of the light shielding unit 12 is finally increased, and the light transmittance of the display panel is improved.

As shown in fig. 1 to 8, the orthographic projection of the bottom surface 1231 of the second light shielding portion 123 on the first substrate 10 is located in the central region of the orthographic projection of the top surface 1233 of the second light shielding portion 123 on the first substrate 10. To ensure that the pitch between the inclined side circumferential surface 1232 of the second light shielding portion 123 and each color resist unit 13 adjacent thereto is almost equal, so that the amount of light reflected by the reflective side circumferential surface 122a of the reflective layer 1221 disposed on the inclined side circumferential surface 1232 into each color resist unit 13 is almost equal, and finally, the light emitted from the color resist unit 13 is uniform.

As shown in fig. 8, the reflective portion 122 further includes a transparent filling layer 1222, and the transparent filling layer 1222 is filled between the reflective layer 1221 and the color blocking unit 13, so as to fill up a gap between the reflective layer 1221 and the color blocking unit 13, and make the heights of the entire light shielding units 12 along the light incident direction of the color film layer 11 equal everywhere.

In this embodiment, the height of the whole light shielding unit 12 along the light incident direction of the color film layer 11 is equal to the height of each color resistance unit 13 along the light incident direction of the color film layer 11, so that the surface of the color film layer 11 away from the first substrate 10 is a horizontal plane, and further the smooth lamination of the color film layer 11 and other film layers is facilitated, and meanwhile, the protrusion of the light shielding unit 12 relative to the color resistance units 13 along the light incident direction of the color film layer 11 is avoided, so as to affect the uniform diffusion of light.

For example, the transparent filler layer 1222 may be formed of glass having good polishing performance and a small expansion coefficient.

It should be understood that after the transparent filling layer 1222 is filled between the reflective layer 1221 and the color resist unit 13, there is no gap between the reflective layer 1221 and the color resist unit 13.

To sum up, in the embodiment, when the light emitted from the light source is obliquely directed to the light shielding unit 12 from the color blocking unit 13, a part of the light is obliquely irradiated on the first light shielding portion 121 and absorbed by the light shielding portion, and another part of the light is obliquely irradiated on the reflective side peripheral surface 122a opposite to the color blocking unit 13, and then the part of the light is reflected into the color blocking unit 13 through the reflective side peripheral surface 122a, and sequentially passes through the color blocking unit 13 and the first substrate 10 and is emitted. Therefore, the light transmittance of the display panel is improved as compared with the case where the light is absorbed by the whole light shielding unit 12 after being obliquely emitted from the color blocking unit 13.

Also, some light rays vertically incident between the light shielding body 12a and the color blocking unit 13 will also be irradiated on the reflective layer 1221, and reflected into the color blocking unit 13 through the reflective layer 1221, and then sequentially pass through the color blocking unit 13 and the first substrate 10 and be emitted; therefore, compared with the light absorbed by the light shielding unit 12, the light transmittance of the display panel is further improved, and the energy consumption of the display panel is reduced.
