It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to fall within the scope of the application.
Referring to fig. 1, fig. 1 is a top view diagram of a conventional reflective lcd panel, in which in a sub-pixel unit, when a color block unit covers the sub-pixel unit, the color gamut of the light emitted from the display panel is higher, but the brightness of the light emitted from the display panel is lower due to the full coverage of the color block unit, the reflectivity of the display panel for incident light is 4% to 8%, and the color gamut of the light emitted from the display panel for NTSC is 20% to 60%.
Referring to fig. 2, in order to ensure the brightness of the display panel, a plurality of white areas are generally disposed on the color block unit to form a plurality of equally divided structures on the color block unit 300, wherein the brightness of the display panel of the structure is higher, but the brightness of the light-emitting area is lower, so that the display effect is poor; in the structure of fig. 2, the color block unit 300 is divided into two sub-units 310 with equal areas, the reflectivity of the display panel for the incident light is 8% to 16%, the NTSC color gamut of the emergent light is 5% to 20%, that is, the more the color block unit 300 is divided into equal parts, the higher the brightness of the emergent light and the lower the color range of the emergent light.
Referring to fig. 3 to 8, the present application provides a display panel 100, which includes a color blocking layer 22 and a reflective layer 121, wherein the reflective layer 121 is disposed on one side of the color blocking layer 22.

In this embodiment, the thickness of the first color block 31 may be greater than the thickness of the second color block 32.
It should be noted that, the display panel 100 of the present application is mainly a reflective liquid crystal display panel 100, i.e. no backlight is needed, and the display panel displays images mainly by reflecting ambient light or light emitted by a light source disposed in front of the display panel 100, so that the power consumption is low.
It should be noted that the ratio of the thickness of the second color block 32 to the thickness of the first color block 31 may be in the range of 0.1 to 0.9.
In the top view of the display panel 100, the first color block 31 has a regular shape such as a diamond shape, a trapezoid shape, or a rectangle shape. The shape of the first color block 31 is not particularly limited as long as the area ratio of the second color block 32 is ensured to be smaller than the area ratio of the first color block 31, for example, in the configuration shown in fig. 3 to 5, the shape of the first color block 31 is rectangular.

Referring to fig. 3, the display panel 100 may include an array substrate 10, a color film substrate 20, and a liquid crystal layer 30 disposed between the array substrate 10 and the color film substrate 20.
In this embodiment, the array substrate 10 may be a conventional structure or a COA (Color Filter On Array, color film layer disposed on the substrate of the array), which is not particularly limited in the present application. In the following embodiments, the present application is illustrated by taking a conventional array substrate 10 as an example.
In this embodiment, the array substrate 10 may include a first substrate 11, a driving circuit layer 12 on the first substrate 11, and a first common electrode layer on the driving circuit layer 12.

In this embodiment, the first common electrode layer is located on the passivation layer 128 and is electrically connected to the source/drain electrode in the source/drain electrode layer 127 through the via hole of the passivation layer 128. The first common electrode layer may also be referred to as a pixel electrode for providing a first voltage for deflection of liquid crystal molecules.

In this embodiment, the color filter substrate 20 may include a second substrate 21, the color resist layer 22 disposed on the second substrate 21, and a second common electrode layer 23 disposed on the color resist layer 22.
In this embodiment, the material of the second substrate 21 may be the same as the material of the first substrate 11.
In this embodiment, the second common electrode layer 23 is used to provide a second voltage for liquid crystal molecule deflection. The second voltage is a constant voltage, and the display panel 100 changes the voltage difference between two sides of the liquid crystal layer 30 by changing the first voltage so that the liquid crystal molecules deflect at different angles. The material of the second common electrode layer 23 may be ITO.
In this embodiment, the color resist layer 22 may include a plurality of red color resist units, a plurality of green color resist units, and a plurality of blue color resist units, and a light shielding unit may be disposed between two adjacent color resist units 300.
In this embodiment, the display panel 100 further includes the reflective layer 121 on one side of the color resist layer 22. The external incident light is incident into the display panel 100, and after passing through the color resist layer 22, is reflected to the light emitting side of the display panel 100 by the reflective layer 121.
In the present embodiment, the position of the reflective layer 121 is not particularly limited, for example, when the reflective layer 121 is located between the color resist layer 22 and the second substrate 21, the incident light incident on the side of the array substrate 10 is incident on the reflective layer 121 through the liquid crystal layer 30 and the color resist layer 22, and the reflective layer 121 reflects the incident light to the light outgoing side of the display panel 100 through the color resist layer 22 and the liquid crystal layer 30, that is, the array substrate 10 of the display panel 100 can be used as both the light incoming side and the light outgoing side; in addition, the reflective layer 121 may be further located on the side of the array substrate 10, for example, the reflective layer 121 may be disposed between the first substrate 11 and the liquid crystal layer 30, that is, the color film substrate 20 may be used as the light incident side, the incident light may be incident on the reflective layer 121 through the color resist layer 22 and the liquid crystal layer 30, and the reflective layer 121 may reflect the incident light to the light emergent side of the display panel 100 through the liquid crystal layer 30 and the color resist layer 22, that is, the color film substrate 20 of the display panel 100 may be used as both the light incident side and the light emergent side.
In this embodiment, the material of the reflective layer 121 may be a metal material with high reflectivity, such as aluminum or silver.
Referring to fig. 4, the display panel 100 may include a plurality of Data lines Data and a plurality of scan lines Gate, wherein the Data lines Data and the scan lines Gate enclose a plurality of sub-pixel units 200, and one sub-pixel unit 200 includes one color resist unit 300 and a pixel electrode (not shown) corresponding to the color resist unit 300.
In this embodiment, referring to fig. 5, in one color block unit 300, the area ratio of the first color block 31 is larger than the area ratio of the second color block 32.
In this embodiment, referring to fig. 5, in one of the color blocks 300, the second color block 32 may have a cross structure, and the second color block 32 separates one of the color blocks 300 into 4 of the first color blocks 31.
In this embodiment, the area of each of the first color blocks 31 may be equal.
In this embodiment, since the thickness of the second color block 32 is smaller than the thickness of the first color block 31, if the area ratio of the second color block 32 is too large, the overall thickness of one color block 300 will decrease, the brightness of the display panel 100 will increase, but the improvement of the brightness area will be small, i.e. the improvement of the display effect of the display panel 100 will be small, so that the area ratio of the first color block 31 is larger than the area ratio of the second color block 32, which can increase the brightness of the brightness area of the display panel 100 as much as possible.
In the display panel 100 of the present application, referring to fig. 5, the second color block 32 may include a second lateral color block 321 extending along a first direction X and a second longitudinal color block 322 extending along a second direction Y, where the first direction X and the second direction Y are perpendicular to each other.
In this embodiment, the width a of the second lateral color block 321 along the second direction Y is greater than the width b of the second longitudinal color block 322 along the first direction X.
Referring to fig. 5, the first direction X may be parallel to the extending direction of the scan line Gate, the second direction Y may be parallel to the extending direction of the Data line Data, and the second lateral color block 321 and the second longitudinal color block 322 may divide the color block unit 300 into 4 first color blocks 31 with equal areas.
For example, when the first direction X is taken as the left-right viewing angle of the display panel 100 and the second direction Y is taken as the up-down viewing angle of the display panel 100, the width of the second lateral color block 321 along the second direction Y increases to reduce the color gamut of the up-down viewing angle, and the width of the second longitudinal color block 322 along the first direction X decreases to increase the color gamut of the left-right viewing angle and improve the effect of the display panel 100; in the present application, by reducing the width of the second longitudinal color block 322 along the first direction X, the area ratio of the first color block 31 in the first direction X is increased, so that more reflected light rays will penetrate the color block unit 300, the color gamut of the display panel 100 in the left and right viewing angles is increased, and the display effect of the display panel 100 is further improved.
Referring to fig. 5 and 6, the pixel electrode 13 in one sub-pixel unit 200 may include a main electrode 131 and a branch electrode 132 connected to the main electrode 131, the main electrode 131 divides the pixel electrode 13 into a plurality of pixel sub-regions 130, the pixel sub-regions 130 correspond to the first color block 31, and the main electrode 131 corresponds to the second color block 32.
In the present embodiment, for the liquid crystal display panel 100, the pixel sub-region 130 corresponding to the branch electrode 132 is a light-transmitting region, and the region corresponding to the main electrode 131 is a non-light-transmitting region; in the present application, the pixel sub-area 130 and the first color block 31 are correspondingly arranged, and the incident light can pass through the pixel sub-area 130 and the first color block 31 at the same time and be led out from the light emitting side of the display panel 100; secondly, the main electrode 131 corresponds to the second color block 32, and since the area corresponding to the main electrode 131 is a non-light-transmitting area, the orthographic projection of the main electrode 131 on the second color block 32 is located in the second color block 32, that is, the area of the main electrode 131 is smaller than the area of the second color block 32, that is, in the top view direction of the display panel 100, the second color block 32 covers the main electrode 131 and extends towards the pixel sub-area 130, and overlaps with the branch electrode 132 in the pixel sub-area 130, so that the color gamut and the reflectivity of the display panel 100 are adjusted by adjusting the thickness of the second color block 32.
In this embodiment, the orthographic projection area of the first color block 31 on the pixel sub-area 130 is smaller than the area corresponding to the pixel sub-area 130. The second color block 32 overlaps the branch electrode 132 in the pixel sub-area 130, i.e. the area of the first color block 31 is smaller than the area of the pixel sub-area 130, and the dual adjustment of the size and thickness of the area of the second color block 32 adjusts the color gamut and reflectivity of the display panel 100.
