Description
Technical Field
The invention relates to the technical field of display, in particular to a pixel structure and an OLED display panel comprising the same.
Background
An OLED (Organic Light-Emitting Diode) is an active Light-Emitting device. Compared with the traditional LCD (Liquid Crystal Display) Display mode, the OLED Display technology does not need a backlight lamp and has the self-luminous characteristic. The OLED adopts a thin organic material film layer and a glass substrate, and when a current flows, the organic material can emit light. Therefore, the OLED display panel can save electric energy remarkably, can be made lighter and thinner, can endure a wider range of temperature variation than the LCD display panel, and has a larger visual angle. The OLED display panel is expected to become a next-generation flat panel display technology following the LCD, and is one of the technologies that receives the most attention among the flat panel display technologies at present.
There are many colorization methods for OLED screens, and the OLED colorization technology that is mature and has been successfully mass-produced is mainly the OLED evaporation technology, which uses the conventional RGB Stripe arrangement for evaporation. The best picture effect is the side-by-side (juxtaposition) mode. The side-by-side method is characterized in that three sub-pixels (R, G, B) of red, green and blue are arranged in a Pixel (Pixel) range, each sub-Pixel is quadrilateral and is provided with an independent organic light-emitting component, the organic light-emitting components are formed at corresponding Pixel positions on an array substrate through a high-precision Metal Mask (FMM) by utilizing an evaporation film forming technology, and the high-precision Metal Mask is usually referred to as a Metal Mask or an evaporation Mask for short. The technical focus of fabricating high PPI (Pixel Per Inch, number of pixels) OLED display panels is on the FMM with fine and mechanical stability and the arrangement of the pixels (sub-pixels).
Fig. 1 is a schematic diagram of a pixel arrangement of an OLED display panel in the prior art. As shown in fig. 1, the OLED display panel adopts a Pixel juxtaposition manner, each Pixel unit Pixel includes an R sub-Pixel region 101, a G sub-Pixel region 103 and a B sub-Pixel region 105, wherein the R sub-Pixel region 101 includes an R emitting region 102 and an R non-emitting region (not numbered), the G sub-Pixel region 103 includes a G emitting region 104 and a G non-emitting region (not numbered), and the B sub-Pixel region 105 includes a B emitting region 106 and a B non-emitting region (not numbered). The R, G, B subpixels in FIG. 1 have equal areas of area and light emitting area, respectively, and the R, G, B subpixels are arranged in a straight line. Specifically, in the light emitting region of each sub-pixel region, a cathode electrode, an anode electrode, and an electroluminescent layer (also referred to as an organic emission layer) between the cathode electrode and the anode electrode for generating light of a predetermined color to realize display are included. In the preparation of the display panel in the prior art, three times of evaporation processes are generally required to form electroluminescent layers of corresponding colors (red, green or blue) in the light-emitting regions of the pixel regions of the corresponding colors, respectively.
The OLED display panel shown in fig. 1 is usually evaporated by using the FMM shown in fig. 2, which includes a shielding region 107 and a plurality of evaporation openings 108, and the shielding region between two adjacent evaporation openings 108 in the same column is called a bridge (bridge). In order to avoid the shielding effect on the sub-pixels during evaporation, a sufficient distance must be kept between the sub-pixels and the bridge, which results in the reduction of the length of the sub-pixels above and below, and affects the aperture ratio of each sub-pixel. With the increasing demand of users for the resolution of the OLED display panel, the RGB pixel juxtaposition method has not been able to meet the design requirement of high PPI of the product.
Fig. 3 is a schematic diagram of a pixel arrangement of another OLED display panel in the prior art. As shown in fig. 3, each Pixel unit Pixel includes an R sub-Pixel region 201, a G sub-Pixel region 203 and a B sub-Pixel region 205, wherein the R sub-Pixel region 201 includes an R emitting region 202 and an R non-emitting region, the G sub-Pixel region 203 includes a G emitting region 204 and a G non-emitting region, and the B sub-Pixel region 205 includes a B emitting region 206 and a B non-emitting region. The R, G sub-pixels shown in fig. 3 have equal areas and light-emitting areas, respectively, and the three sub-pixels are arranged in a chevron or inverted chevron, while the B light-emitting areas 206 on the same column are arranged in a straight line.
Fig. 4 is a schematic diagram of an FMM corresponding to the R sub-pixel or the G sub-pixel of fig. 2A, wherein the FMM includes a shielding region 207 and an evaporation opening 208. Fig. 5 is a schematic diagram of an FMM corresponding to the B sub-pixel of fig. 3, which includes a shielding region 209 and an evaporation opening 210. In this pixel arrangement, the pixels are periodically translated horizontally and vertically to form a row and column pixel array. The opening space of the evaporation mask plate corresponding to the red and green sub-pixels is relatively large, and high PPI display can be realized to a certain extent. However, as a result of the above-mentioned periodic arrangement of the pixels, the B sub-pixels in the pixel array form a linear arrangement, and due to the limitation of the FMM fabrication capability, there is a certain requirement for the Bridge (the Bridge must reach a certain size), which affects the further improvement of the aperture ratio of the B sub-pixels.

Detailed Description
As described in the background section, the applicant has found that the conventional RGB pixel arrangement can not meet the requirements of aperture ratio and display effect of the product. Based on the above, the present invention provides a pixel structure of an OLED display panel, where each pixel unit is composed of only two subpixels arranged along a first direction and having different colors, and each pixel unit includes subpixels, which have different colors from the two subpixels, in a pixel unit adjacent to the second direction, and different colors can be displayed by the subpixels, which have different colors, in the pixel unit adjacent to the second direction, so that the size of an evaporation opening on an evaporation mask can be increased under the condition of the same size of a connection bridge, thereby increasing the area of a light emitting area of the subpixel, or increasing the size of the connection bridge on the evaporation mask, and reducing the difficulty of the mask manufacturing process and the evaporation process. In addition, two adjacent pixel units in the first direction are arranged in a mirror symmetry manner, so that the sub-pixels with the same color in the two adjacent pixel units in the same row can be formed by using the same evaporation opening, and the area of the light emitting areas of the sub-pixels can be further increased.
The pixel structure and the OLED display panel according to the present invention will be described in detail with reference to the accompanying drawings and specific embodiments. Advantages and features of the present invention will become apparent from the following description and from the claims. It is to be noted that the drawings are in a very simplified form and are not to precise scale, which is merely for the purpose of facilitating and distinctly claiming the embodiments of the present invention.
Example one
Here, the X direction is referred to as a row direction (lateral direction), and the Y direction is referred to as a column direction (longitudinal direction). For simplicity, only a portion of the OLED display panel is shown in the drawings, and the number of pixels in an actual product is not limited thereto, for example, only 4 rows by 4 columns of pixel units are shown in fig. 6, but actually, the number of pixel units may be changed accordingly according to actual display requirements. The first row, the second row, the first column, the second column, etc. are illustrated in the drawings as reference standards for explaining the present invention, and do not refer to the rows and columns in the actual product. In fig. 6, the pixel cell in the first row and the first column is referred to as a pixel cell (1, 1), the pixel cell in the first row and the second column is referred to as a pixel cell (1, 2), the pixel cell in the second row and the first column is referred to as a pixel cell (2, 1), the pixel cell in the second row and the second column is referred to as a pixel cell (2, 2), and so on.
The first direction and the second direction are perpendicular to each other, for example, the first direction is a row direction (X direction), and the second direction is a column direction (Y direction). As shown in fig. 6, all the pixel units in the odd-numbered rows are composed of the first subpixel 301 and the second subpixel 302 arranged in the row direction, and all the pixel units in the even-numbered rows are composed of the second subpixel 302 and the third subpixel 303 arranged in the row direction, so that the pixel units can display different colors by using the subpixels of different colors in the pixel units adjacent to each other in the column direction. For example, the pixel cell of the first row borrows the nearest third subpixel 303 of the second row when displaying color, and similarly, the pixel cell of the second row borrows the first subpixel 301 in the first row or the third row when displaying color. Specifically, as shown in fig. 6, the pixel unit (1, 1) in the first row and the first column is composed of a first sub-pixel 301 and a second sub-pixel 302, and the pixel unit (2, 1) in the second row and the first column is composed of a second sub-pixel 302 and a third sub-pixel 303, so that the pixel unit (1, 1) in the first row and the first column can display various colors by using the third sub-pixel 303 in the pixel unit (2, 1) in the second row and the first column, and similarly, the pixel unit (2, 1) in the second row and the first column can display various colors by using the first sub-pixel 301 in the pixel unit (1, 1) in the first row and the first column or the pixel unit (3, 1) in the third row and the first column.
In addition, two adjacent pixel units in the first direction, i.e. the row direction, are arranged in a mirror symmetry manner, so that the sub-pixels with the same color in two adjacent pixel units in the same row are arranged in close proximity (back to back), and can be formed by using the same evaporation opening. For example, the pixel units (1, 1) in the first row and the first column and the pixel units (1, 2) in the first row and the second column are arranged in a mirror symmetry manner, and the second sub-pixels in the pixel units (1, 1) in the first row and the first column and the second sub-pixels in the pixel units (1, 2) in the first row and the second column can be formed by co-evaporation through the same evaporation opening. The size of the connecting bridge (bridge) on the evaporation mask can be increased under the condition of the same aperture ratio, the difficulty of the mask manufacturing process and the evaporation process is reduced, or the aperture ratio of the sub-pixel is improved under the condition of the same bridge size, or the bridge size is properly increased and the aperture ratio of the sub-pixel is improved.
As shown in fig. 6, two adjacent sub-pixels in the second direction, i.e., the column direction, are different in color, that is, the pixel unit of the odd-numbered row is composed of the first sub-pixel 301 and the second sub-pixel 302 arranged in the row direction, the pixel unit of the even-numbered row is composed of the second sub-pixel 302 and the third sub-pixel 303 arranged in the row direction, and meanwhile, in the same column, the first sub-pixel 301 in the odd-numbered row and the second sub-pixel 302 in the even-numbered row are arranged on a straight line, and the second sub-pixel 302 in the odd-numbered row and the third sub-pixel 303 in the even-numbered row are arranged on a straight line. In other words, the sub-pixels with the same color in two adjacent rows of pixel units in the same column are not arranged on a straight line, but are distributed diagonally. For example, two second sub-pixels 302 in the pixel unit (1, 1) in the first row and the first column and the pixel unit (2, 1) in the second row and the first column are distributed diagonally.
Each sub-pixel comprises a luminous area (display area) and a non-luminous area (non-display area), the luminous area of each sub-pixel comprises a cathode, an anode and an electroluminescent layer (organic emission layer), and the electroluminescent layer is located between the cathode and the anode and is used for generating light of a preset color to achieve display. It is usually necessary to use three times of evaporation processes to form electroluminescent layers of corresponding colors (such as red, green or blue) in the light-emitting regions of the pixel regions of corresponding colors, respectively.
In this embodiment, the first sub-pixel 301 is a red (R) sub-pixel, the second sub-pixel 302 is a green (G) sub-pixel, and the third sub-pixel 303 is a blue (B) sub-pixel; accordingly, the first sub-pixel 301 includes an R-emitting region and an R-non-emitting region, and includes an organic emission layer for emitting red light; the second sub-pixel 302 includes a G light emitting region and a G non-light emitting region, and includes an organic emission layer for emitting green light; the third sub-pixel 303 includes a B light emitting region and a B non-light emitting region, and includes an organic emission layer for emitting blue light. It should be appreciated that the relative positions of the sub-pixels may be RG arrangement for odd rows and GB arrangement for even rows as shown in fig. 6, GR arrangement for odd rows and RB arrangement for even rows, BG arrangement for odd rows and GR arrangement for even rows.
In this embodiment, the first sub-pixel 301, the second sub-pixel 302, and the third sub-pixel 303 are all rectangular and have the same area. Specifically, the first sub-pixel 301 and the second sub-pixel 302 in the pixel unit of the odd-numbered row are arranged in the short side direction, and similarly, the second sub-pixel 302 and the third sub-pixel 303 in the pixel unit of the even-numbered row are also arranged in the short side direction. It is understood that the shapes of the first sub-pixel 301, the second sub-pixel 302 and the third sub-pixel 303 are not limited to a rectangle, and may be quadrangles other than a rectangle, or one or any combination of polygons such as a triangle, a pentagon, a hexagon and an octagon, or a circle or an ellipse. Meanwhile, the areas of the first sub-pixel 301, the second sub-pixel 302 and the third sub-pixel 303 may also be unequal, and the shape and/or the area of each sub-pixel may be adjusted according to the color matching requirement.
The FMM corresponding to the first sub-pixel 301 or the second sub-pixel 302 includes a shielding region and an evaporation opening. Since the first sub-pixel 301 and the second sub-pixel 302 have the same shape and area and the same arrangement, the same FMM may be used to perform evaporation twice, or two FMMs may be used to perform evaporation respectively. In this embodiment, the sub-pixels with the same color in two adjacent pixel units on the same row may be formed by using the same evaporation opening on the evaporation mask, and the light emitting areas of the two sub-pixels are defined by the anode and the cathode. For example, the second sub-pixel in the pixel unit (1, 1) in the first row and the first column and the second sub-pixel in the pixel unit (1, 2) in the first row and the second column are formed by evaporation through the same evaporation opening, the first sub-pixel in the pixel unit (1, 2) in the first row and the second column and the first sub-pixel in the pixel unit (1, 3) in the first row and the third column are formed by evaporation through the same evaporation opening, and so on. As described above, two sub-pixels are formed by evaporation through the same evaporation opening on the evaporation mask, the size of the Bridge is not limited, and the pitch of the two sub-pixels formed by evaporation through the same evaporation opening can be designed to be smaller, so that the opening area of the FFM can be increased, and the aperture opening ratio can be improved; of course, the size of the Bridge can be increased under the condition of a certain aperture opening ratio, so that the strength of the evaporation mask plate is enhanced.
Example two
As shown in fig. 7, this embodiment is different from the first embodiment in that four adjacent pixel units on the same column form a pixel group, and in each pixel group, two pixel units in the middle are composed of a second sub-pixel 302 and a third sub-pixel 303 arranged in the row direction, and the other two pixel units are composed of a first sub-pixel 301 and a second sub-pixel 302 arranged in the row direction. For example, the pixel units in the first row and the pixel units in the fourth row are arranged in the same manner and are both composed of the first sub-pixel 301 and the second sub-pixel 302, while the pixel units in the middle two rows, i.e., the second row and the third row, are arranged in the same manner and are both composed of the second sub-pixel 302 and the third sub-pixel 303.
Wherein, each pixel unit only contains sub-pixels of two colors, and the sub-pixels of the other color are distributed in the pixel units of adjacent rows. Specifically, the first sub-pixel 301 is a red (R) sub-pixel, the second sub-pixel 302 is a green (G) sub-pixel, and the third sub-pixel 303 is a blue (B) sub-pixel, so that the pixel unit in the first row only includes the red sub-pixel and the green sub-pixel, the pixel unit in the second row only includes the blue sub-pixel and the green sub-pixel, the third row is the same as the second row, and the fourth row is the same as the first row.
In addition, two adjacent pixel units in the first direction, i.e. the row direction, are arranged in a mirror symmetry manner, meanwhile, in each pixel group, the structures of the two middle rows of pixel units are the same, and the structure of the last row of pixel unit of each pixel group is the same as that of the first row of pixel unit, so that the sub-pixels with the same color in the two adjacent pixel units in the same row are arranged in close proximity (back to back), and in each pixel group, the sub-pixels with the same color in the two pixel units in the middle two rows in the same column are arranged in close proximity (back to back), and the sub-pixels with the same color in the two pixel units in the last row of the previous pixel group and the first row of the next pixel group are arranged in close proximity (back to back), so that the sub-pixels with the same color in the four adjacent pixel units are formed by adopting the same evaporation opening. As shown by the dashed line in the direction of fig. 7, the second sub-pixels 302 in the pixel units (2, 2) in the second row and the second column, the pixel units (2, 3) in the second row and the third column, the pixel units (3, 2) in the third row and the second column, and the pixel units (3, 3) in the third row and the third column are disposed next to each other, and may be formed by using the same evaporation opening.
As shown in fig. 7, in the present embodiment, the relative positions of the sub-pixels are the RG array and the GB array, respectively, but in other embodiments, the GR array and the RB array, respectively, or the BG array and the GR array, respectively, may be used.
EXAMPLE III
As shown in fig. 8, the present embodiment is different from the first embodiment in that all the pixel units of the odd-numbered rows are composed of the first sub-pixel 301 and the second sub-pixel 302 arranged in the row direction, and all the pixel units of the even-numbered rows are composed of the fourth sub-pixel 304 and the third sub-pixel 303 arranged in the row direction.
Wherein, each pixel unit only contains two colors of sub-pixels, and the other two colors of sub-pixels are distributed in the adjacent rows of pixel units. Specifically, the first sub-pixel 301 is a red (R) sub-pixel, the second sub-pixel 302 is a green (G) sub-pixel, the third sub-pixel 303 is a blue (B) sub-pixel, and the fourth sub-pixel 304 is a white (W) sub-pixel, so that all the odd-numbered rows of pixel units only include the red sub-pixel and the green sub-pixel, and all the even-numbered rows of pixel units only include the blue sub-pixel and the white sub-pixel. Thus, the pixel unit can display different colors by means of the sub-pixels of different colors in the pixel units adjacent in the column direction. For example, the pixel unit of the first row borrows the nearest third subpixel 303 and/or fourth subpixel 304 of the second row when displaying color, and similarly, the pixel unit of the second row borrows the first subpixel 301 and/or the second subpixel 302 of the first row or the third row when displaying color.
In addition, two adjacent pixel units in the first direction, i.e. the row direction, are arranged in a mirror symmetry manner, so that the sub-pixels with the same color in two adjacent pixel units in the same row are arranged in close proximity (back to back), and can be formed by using the same evaporation opening. For example, the pixel units (1, 1) in the first row and the first column and the pixel units (1, 2) in the first row and the second column are arranged in a mirror symmetry manner, and the second sub-pixels in the pixel units (1, 1) in the first row and the first column and the second sub-pixels in the pixel units (1, 2) in the first row and the second column can be formed by co-evaporation through the same evaporation opening.
As shown in fig. 8, in the present embodiment, the odd-numbered lines are RG-arranged and the even-numbered lines are WB-arranged, and in other embodiments, the colors of the sub-pixels may be switched, for example, the odd-numbered lines are GR-arranged, the even-numbered lines are WB-arranged, the odd-numbered lines are RG-arranged, the even-numbered lines are BW-arranged, the odd-numbered lines are GR-arranged, the even-numbered lines are WB-arranged, and so on.
Example four
As shown in fig. 9, this embodiment is different from the first embodiment in that four adjacent pixel units on the same column form a pixel group, and in each pixel group, two pixel units in the middle are composed of a third sub-pixel 303 and a fourth sub-pixel 304 arranged in the row direction, and the other two pixel units are composed of a first sub-pixel 301 and a second sub-pixel 302 arranged in the row direction. For example, the pixel units in the first row and the pixel units in the fourth row are arranged in the same manner and are composed of the first sub-pixel 301 and the second sub-pixel 302, while the pixel units in the middle two rows, i.e., the second row and the third row, are arranged in the same manner and are composed of the third sub-pixel 303 and the fourth sub-pixel 304.
Wherein, each pixel unit only contains two colors of sub-pixels, and the other two colors of sub-pixels are distributed in the adjacent rows of pixel units. Specifically, the first sub-pixel 301 is a red (R) sub-pixel, the second sub-pixel 302 is a green (G) sub-pixel, the third sub-pixel 303 is a blue (B) sub-pixel, and the fourth sub-pixel 304 is a white (W) sub-pixel. In this way, the pixel unit can display different colors by means of sub-pixels different in color in pixel units adjacent in the column direction. For example, the pixel unit of the first row borrows the nearest third subpixel 303 and/or fourth subpixel 304 of the second row when displaying color, and similarly, the pixel unit of the second row borrows the first subpixel 301 and/or the second subpixel 302 of the first row when displaying color.
In addition, two adjacent pixel units in the first direction, i.e. the row direction, are arranged in a mirror symmetry manner, meanwhile, in each pixel group, the structures of the two middle rows of pixel units are the same, and the structure of the last row of pixel unit of each pixel group is the same as that of the first row of pixel unit, so that the sub-pixels with the same color in the two adjacent pixel units in the same row are arranged in close proximity (back to back), and in each pixel group, the sub-pixels with the same color in the two middle rows of pixel units in the same column are arranged in close proximity (back to back), and the sub-pixels with the same color in the two pixel units in the last row of the previous pixel group and the first row of the next pixel group are arranged in close proximity (back to back), so that the sub-pixels with the same color in the four adjacent pixel units are formed by using the same evaporation opening. As shown by the dashed line in fig. 9, the fourth sub-pixels 304 in the pixel units (2, 2) in the second row and the second column, the pixel units (2, 3) in the second row and the third column, the pixel units (3, 2) in the third row and the second column, and the pixel units (3, 3) in the third row and the third column may be formed by using the same evaporation opening.
