First, for further understanding, some relevant matters regarding the color set elements will be described below.
In the field of display technology, taking a liquid crystal display as an example, since a backlight of the liquid crystal display emits white light, a Color Filter (CF) is required to be used for Color display of the liquid crystal display. A color filter, also called a color set, is an optical filter that can precisely select the filtered light segment to be passed through, while filtering out other filtered light segments that are not desired to be passed through.
A general structure of the color filter may include a glass substrate, a silicon dioxide film, a black matrix, a color layer, a protective film, and a conductive film. The glass substrate, the silicon dioxide film, the black matrix, the color layer, the protective film, and the conductive film may be sequentially stacked from bottom to top. The color layer can be regarded as a color set layer, and comprises a plurality of color set units. Each color group unit may be composed of three sub-color group units representing three primary colors of red, green and blue, and correspond to sub-pixels in the liquid crystal display one to one.
In practical application, white light emitted by a backlight source of the liquid crystal display can be converted into corresponding red light, green light and blue light after passing through a color filter; the transmission intensity of each color light can be changed by adjusting the voltage value applied to each sub-pixel to obtain each color light with different intensity, and then each color light with different intensity is mixed, thereby realizing color display.
Fig. 1 shows a schematic diagram of a color set unit in the related art.
As shown in fig. 1, in the related art, the color grouping unit 10 includes a red sub-color grouping unit 101, a blue sub-color grouping unit 102, and a green sub-color grouping unit 103. The display panel may include a plurality of color set units, and the plurality of color set units may be arranged in rows and columns to form a color set unit array. The color burst element 10 may be any color burst element in an array of color burst elements of a display panel.
With continued reference to fig. 1, the color grouping unit 10 may be a top view of the color grouping unit, and a section line 12 may cut the color grouping unit 10 from the location of the section line in a direction into the paper. The color set cell 11 represents a cross section of the color set cell 10 cut by a sectional line 12. As can be seen from the cross section, the thicknesses of the sub-color set units in the color set unit 10 are the same, and thus the thicknesses of the color set units are the same, that is, the light transmittances of the light passing through the color set units in the display panel in the related art are the same, and the display area in the related art usually adopts the full-area color set design, that is, the color set units are all in the light transmitting area of the entire display panel, such a design is not particularly suitable for the display panel with high resolution and high pixel density, and may cause the energy consumption of the display panel to be too high.
In view of the foregoing, the present application provides a display panel, which includes a color resist layer, wherein the color set layer includes a plurality of color set units, a first color set region and a second color set region are disposed in a region of the color set layer, and a light transmittance of the first color set region is smaller than a light transmittance of the second color set region. Through setting up the colour group region that has different luminousness, the regional luminousness of colour group can be promoted in this application, and then promotes the holistic transmissivity of display panel, reaches and reduces display panel consumption and energy-conserving effect.
Fig. 2 shows a schematic diagram of a display panel according to an embodiment of the present application.
As shown in fig. 2, the color grouping layer 20 of the display panel includes a plurality of color grouping units, and the color grouping unit 23 may be any one of the plurality of color grouping units. The plurality of color set units can be arranged in rows and columns to form a color set unit array. The number of color grouping units is not limited in the present application.
Further, in fig. 2, a first color set region 21 and a second color set region 22 are disposed in the region where the color set layer is located, wherein the light transmittance of the first color set region 21 is smaller than that of the second color set region 22. In addition, the light transmittance of the first color set region 21 may be greater than or equal to the light transmittance of the second color set region 22. The relative size of this application to the luminousness of first look group region and the luminousness of second look group region does not restrict, as long as the luminousness of first look group region and the luminousness of second look group region are different can.
For example, the first color set region 21 may include 3 color set units, and the second color set region 22 may include 6 color set units. For convenience of description, the color grouping unit in the color grouping layer 20 can be represented in the form of coordinates, for example, the color grouping unit in the upper left corner can be represented as color grouping unit (1,1) (i.e., the color grouping unit in the first row and the first column).
Further, a plurality of color set units are disposed in the first color set region, and the thickness of each color set unit in the first color set region may be the same, that is, the light transmittance of each color set unit in the first color set region is the same.
In one example, as shown in fig. 2, the first color set region 21 may include color set units (1,1), color set units (2,1), and color set units (3,1), and thicknesses in the color set units (1,1), the color set units (2,1), and the color set units (3,1) may be respectively set as needed. For example, the thicknesses in the color set unit (1,1), the color set unit (2,1), and the color set unit (3,1) may all be the same.
Further, as shown in fig. 2, the second color set region 22 may include color set units (1,2), color set units (2,2), color set units (3,2), color set units (1,3), color set units (2,3), and color set units (3, 3). In the second color set region 22, the thickness of each color set unit may be different. For example, the thickness of the color set unit (1,2) may be 5mm, and the thickness of the color set unit (2,2) may be 3 mm. In addition, the thicknesses of the partial color set units may be the same. For example, the thickness of both the color set elements (1,2) and (2,2) may be 5mm, while the thickness of both the color set elements (3,2) and (1,3) may be 3 mm. That is, the plurality of color set units in the second color set region may be further grouped, the thicknesses of the color set units located in the same group may be the same, and the thicknesses of the color set units located in different groups may be different.
It should be noted that, the thicknesses of the plurality of color set units in the first color set region may also be different, as long as the light transmittance of the first color set region is different from that of the second color set region, and how to make the light transmittance of the first color set region different from that of the second color set region is not limited in the present application.
Furthermore, a plurality of color set units are arranged in the first color set region, and a first region with a hollowed color resistance layer is arranged in the second color set region. The second color set region may be partially or completely hollow. And no color set unit is arranged in the first area with the hollowed color set layer.
Furthermore, a second area is arranged in the second color set area, a plurality of color set units are arranged in the second area, and the thickness of any color set unit in the second area is smaller than that of any color set unit outside the second area. That is, the thickness of all the color set units in the second region is smaller than the thickness of any color set unit outside the second region. In addition, the thickness of a part of the color set units in the second region may be greater than or equal to the thickness of any color set unit outside the second region, which is not limited in this application.
It should be noted that, since the color group units in the display panel are generally disposed in the color group layer, any color group unit located outside the second area is also located in the area where the color group layer is located. In addition, the first region and the second region may be simultaneously disposed in the second color set region. Accordingly, the first region, the second region, or both the first region and the second region may be set in the first color set region, and how to set the first region and the second region is not limited in the present application.
Fig. 3 shows a schematic diagram of a display panel according to an embodiment of the present application.
As shown in fig. 3, the color grouping layer 20 of the display panel includes a plurality of color grouping units, and the color grouping unit 23 may be any one of the plurality of color grouping units. The plurality of color set units can be arranged in rows and columns to form a color set unit array. The color set layer is provided with a first color set region 21 and a second color set region 22 in the region, wherein the light transmittance of the first color set region 21 is less than that of the second color set region 22.
Further, referring to fig. 3, the second color set region 22 may have a first region 221 and a second region 222 disposed therein. The first region 221 may include color set units (1,2), color set units (2,2) and color set units (3,2), and the second region 222 may include color set units (1,3), color set units (2,3) and color set units (3, 3).
Furthermore, in the first area, the color resistance layer is hollow, and no color group unit is arranged. For example, in fig. 3, the first region 221 composed of the color set unit (1,2), the color set unit (2,2), and the color set unit (3,2) is not provided with any color set unit. It is to be noted that, although fig. 2 shows the color gamut units (1,2), the color gamut units (2,2) and the color gamut units (3,2), the color gamut units (1,2), the color gamut units (2,2) and the color gamut units (3,2) are shown by dotted lines, that is, the color gamut units (1,2), the color gamut units (2,2) and the color gamut units (3,2) are used to indicate the range of the first region 221, and do not indicate that the color gamut units (1,2), the color gamut units (2,2) and the color gamut units (3,2) actually exist in the first region 221. Accordingly, the color set unit indicated by the solid line in fig. 3 is actually present, for example, the color set unit (1,1) and the color set unit (3,3) are actually present.
Through setting up first region and second region in the second colour group region to change according to first region and the second region that sets up the thickness of second colour group regional interior colour group unit or the position fretwork that makes the colour group unit place can change the regional luminousness of second colour group, and then make the regional luminousness of second colour group be greater than the luminousness in first colour group region, promote the holistic transmissivity of display panel, reach and reduce display panel consumption and energy-conserving effect.
Further, any color group unit of the color group layer comprises a plurality of sub-color group units. The plurality of sub-color group units can be divided into a plurality of types, including a red sub-color group unit, a green sub-color group unit and a blue sub-color group unit, and the plurality of sub-color group units of different types are combined into a color group unit with a fixed shape.
Further, the plurality of sub-color group units are divided into a plurality of types. For example, the plurality of sub-color group units may include a red sub-color group unit, a green sub-color group unit, and a blue sub-color group unit in terms of color. For another example, the plurality of sub-color group units may further include a red sub-color group unit, a green sub-color group unit, a blue sub-color group unit, and a yellow sub-color group unit. In addition, the plurality of sub-color group units can be classified according to factors such as shapes, and the type of the sub-color group units is not limited in the present application.
Further, a plurality of different types of sub-color group units are combined into one color group unit of a fixed shape. For example, the red, green, and blue sub-color group units may be combined in various common forms such as mosaic, bar, triangle, and quad pixel. Preferably, the red, green and blue sub-color group units may be arranged in order from the left side to the right side in fig. 2 to form a straight stripe type color group unit. The shape of the color set elements is not limited in this application.
Further, each sub-color group unit has different positions, and the thicknesses of the sub-color group units located at different positions are different, that is, the thickness of any one sub-color group unit can be associated with the position of the sub-color group unit. For example, the thickness of each color set unit in the second region may also be set according to the position of the color set unit. In the second region 222 in fig. 3, the thicknesses of the color set units (1,3) and the color set units (3,3) located at the inner edge positions of the second region may be set to 3mm, while the thickness of the color set units (2,3) located at the middle position within the second region may be set to 2 mm.
For another example, the thicknesses of the color set elements in the second region may be set according to an arithmetic progression. For example, the thickness of the color set unit (1,3) is 1mm, the thickness of the color set unit (2,3) is 2mm, the thickness of the color set unit (3,3) is 3mm, that is, the thickness equal difference between the color set units in the second area is 1 mm.
It should be noted that, since any color set unit in the display panel may include a plurality of sub-color set units, the thickness of one color set unit may be represented by an average value of the thicknesses of all sub-color set units in the color set unit. Of course, the thickness of a color set unit may be expressed in other ways, for example, different sub-color set units in the color set unit are given a certain weight, and the thickness of a color set unit may be expressed by a weighted average of the thicknesses of all sub-color set units in the color set unit. Therefore, the thickness of any color set unit in the color resistance layer can be flexibly designed according to requirements. It will be understood by those skilled in the art that the thickness of any one color set element may be related to a variety of factors, such as the purpose, location and shape of the color set element, and the application is not limited to how the thickness of the color set element is shown and arranged.
Further, the color gamut layer comprises a plurality of third color gamut regions, a color gamut unit is arranged in each third color gamut region, each color gamut unit comprises a plurality of sub-color gamut units, a first sub-color gamut region and a second sub-color gamut region are arranged in a target color gamut region in the plurality of third color gamut regions, and the light transmittance of the first sub-color gamut region is smaller than that of the second sub-color gamut region. The target color set region may include one or more third color set regions, which is not limited in this application.
Further, a third area with a hollowed-out colored resistance layer is arranged in the first sub-color group area. For example, any one of the color grouping units of the color grouping layer may include a red color sub-grouping unit, a green color sub-grouping unit, and a blue color sub-grouping unit. The color set layer at the position of the red sub-color set unit in the color set unit can be hollowed out, and the green sub-color set unit and the blue sub-color set unit in the color set unit can be reserved. The green sub-color group unit and the blue sub-color group unit in the color group unit can have the same thickness or different thicknesses. Therefore, in any color set unit of the color set layer, an area with any size can be selected as the third area, the third area can include any number of sub-color set units in the color set unit, and the thickness of the sub-color set unit located outside the third area and inside the color set unit can be flexibly set. The present application is not limited to how the third region is determined and the size of the third region.
Further, the third area may also include a plurality of sub-color set units located in different color set units. For example, for two adjacent color set units, where a red sub-color set unit in one color set unit and a blue sub-color set unit in another color set unit are adjacent to each other, the third region may include the red sub-color set unit in one color set unit and the blue sub-color set unit in another color set unit.
Furthermore, a fourth region is arranged in the second sub-color group region, one or more sub-color group units are arranged in the fourth region, and the thickness of any sub-color group unit in the fourth region is smaller than that of any sub-color group unit outside the fourth region. It should be noted that the sub-color set unit outside the fourth region may be located in the third color set region where the color set unit is located at the same time.
Taking fig. 3 as an example, the color grouping units (1,3) may include a red color sub-grouping unit, a green color sub-grouping unit, and a blue color sub-grouping unit. The thickness of the color grouping layer at the position of the red sub-color grouping unit in the color grouping unit may be reduced, for example, 3mm, that is, the third color grouping region where the red sub-color grouping unit in the color grouping unit is located may be a fourth region, and the green sub-color grouping unit and the blue sub-color grouping unit in the color grouping unit are both located outside the fourth region, so the green sub-color grouping unit and the blue sub-color grouping unit in the color grouping unit may both be kept at 5mm, or the thickness of the green sub-color grouping unit in the color grouping unit is set at 5mm, and the thickness of the blue sub-color grouping unit in the color grouping unit is set at 7 mm.
Further, the fourth region may also include a plurality of sub-color group units located in different color group units. For example, for two adjacent color set units, where a red sub-color set unit in one color set unit and a blue sub-color set unit in another color set unit are adjacent, the fourth region may include a red sub-color set unit in one color set unit and a blue sub-color set unit in another color set unit. The present application does not determine how and the size of the fourth area is determined.
Further, the area where the color group layer is located is an entire area including all color group units, that is, the area where the color group layer is located in this embodiment may represent an entire area including all color group units, rather than a partial area on the color group layer. For example, the color resistance layer may be located in an area having the same size as the area formed by all color group units, or may extend 1mm outwards along the edge of the area formed by all color group units, and is slightly larger than the area formed by all color group units. Similarly, the size of the third color set region may also be the same as the size of the color set unit included in the third color set region, or the third color set region extends outward by 0.1mm along the edge of the color set unit included in the third color set region, and the range of the third color set region determined after the outward extension is not connected to any other color set unit. The present application is not limited to determining the area of the color set layer and the third color set area. Other terms including "region" in the embodiments of the present application should be understood similarly to the region where the color set layer is located and the third color set region.
Fig. 4 shows a schematic diagram of a color set unit of an embodiment of the present application.
As shown in fig. 4, any one of the color burst elements 40 in the color burst area may include a red color burst element 401, a blue color burst element 402, and a green color burst element 403. The sectional line 42 may be cut along the direction from the position of the sectional line toward the paper surface of the color set unit 40, to obtain a sectional plane 41. The white area through which the sectional line passes is the hollowed-out area (i.e., the third area) in each sub-color set unit. That is, any hollowed-out region in fig. 4 may be a partial region in one sub-color set unit.

The sectional line 52 may be cut along the direction from the position of the sectional line toward the paper surface to obtain a sectional plane 51. The light gray area through which the stub passes is the area where the thickness of each sub-color group unit is reduced (i.e., the fourth area). That is, any one of the regions with reduced thickness in fig. 5 may be a partial region in one sub-color group unit.
Further, 501, 502, and 503 in fig. 5 may also respectively indicate a row of red sub-color group units, a row of blue sub-color group units, and a row of green sub-color group units, and the red sub-color group units, the blue sub-color group units, and the green sub-color group units in the same row may constitute a color group unit. Therefore, the light gray area near the sectional line 52 may also indicate that the thickness of some of the sub-color set units in a certain row or certain rows of color set units is set to be reduced. That is, any one of the regions with reduced thickness in fig. 5 may be a region where a plurality of sub-color group units are located.
In the embodiment of the present application, the first region, the second region, the third region, and the fourth region may be disposed in a partial region in the opening region of the display panel, so as to design the achromatic color group unit or reduce the thickness of the partial color group unit. Wherein the opening region may be an effective light transmission region in the display panel. In addition, the size of the opening region can be adjusted according to the transmittance and chromaticity requirements of the whole display panel.
Further, a planarization layer may be further provided in the first region, the second region, the third region, and the fourth region. For example, the first area 221 in fig. 3 may be designed as a colorless unit, and a plurality of pits may be formed in the first area. The pits can be planarized, for example, a material which is completely transparent is used for filling, so that abnormal display of the display panel caused by the pits is avoided. The present application is not limited to how the planarization process is performed.
Further, the transmittance of the whole display panel can be expressed as an average value of the transmittance of each color set unit in the display panel, that is, the transmittance of the whole display panel is related to the transmittance of each color set unit in the display panel. In one example, the larger the area of the region with high light transmittance in the display panel is, the higher the transmittance of the display panel as a whole is, and the more suitable the design of the display panel with high resolution and high pixel density is, which is beneficial to reducing the power consumption of the display panel and saving energy. The present application is not limited to how to determine the transmittance of the entire display panel.
The application also provides a display device, which comprises the display panel.

Fig. 6 shows a schematic diagram of a reticle of an embodiment of the present application.
As shown in fig. 6, a reticle 61 in fig. 6 may be used for the design in fig. 4. The 43 and 44 may respectively represent two areas of the same sub-color set unit, which are not hollowed out, or represent areas of different sub-color set units, which are not hollowed out. In fig. 6, the reticle is designed with two light transmittances. Wherein, Tr% ═ 100% represents that the light transmittance is 100%, that is, the light can completely penetrate through the mask, and the corresponding area is a completely transparent area; tr% — 0% means that the light transmittance is 0%, that is, light is blocked, light cannot pass through the mask, and the corresponding region is a non-light-transmitting region.
Further, the reticle 61 may use a negative photoresist as a photoresist material. That is, the portion of the negative photoresist exposed to light remains, while the portion exposed to light is washed away by the developer. The application is not limited as to the type of photoresist material.
For example, in fig. 6, the color set layer will be retained in the region corresponding to Tr% of 100%, and no color set design will be provided in the region corresponding to Tr% of 0%. Therefore, in the display panel, the light in the area without any color set design can directly pass through the display panel without passing through the color resistor, and the light transmittance of the part is high, so that the integral transmittance of the display panel is improved.
Further, the mask comprises a complete light-transmitting area and a semi-light-transmitting area.
Fig. 7 shows a schematic diagram of a reticle of an embodiment of the present application.
As shown in fig. 7, reticle 71 of fig. 7 may be used for the design of fig. 5. 53 and 54 may respectively represent two regions of the same sub-color group unit with reduced thickness, or represent regions of different sub-color group units with reduced thickness. In fig. 7, the reticle is designed with two light transmittances. Wherein, Tr% ═ 100% represents that the light transmittance is 100%, that is, the light can completely penetrate through the mask, and the corresponding area is a completely transparent area; tr% — 50% means that the light transmittance is 50%, that is, the light partially passes through the reticle, and the corresponding region is a semi-light-transmitting region.
Further, the reticle 71 may employ a negative photoresist as a photoresist material. That is, the portion of the negative photoresist exposed to light remains, while the portion exposed to light is washed away by the developer. The application is not limited as to the type of photoresist material.
For example, in fig. 7, the region corresponding to Tr% of 100% retains the color set layer, and the region corresponding to Tr% of 50% has a reduced thickness. Therefore, in the display panel, the light transmission intensity of the area with the reduced thickness is high, namely the light transmittance of the area is high, and the transmittance of the whole display panel is further improved.
