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 pixel structure.
Background
An OLED (Organic Light-Emitting Diode) is an active Light Emitting device. Compared with the conventional LCD (Liquid CRYSTAL DISPLAY) display mode, the OLED display technology does not need a backlight and has self-luminous property. The OLED adopts a thinner organic material film layer and a glass substrate, and when current passes through the OLED, the organic material emits light. Therefore, the OLED display panel can save electric energy remarkably, can be made lighter and thinner, can withstand a wider range of temperature changes than an LCD display panel, and has a larger viewing angle. The OLED display panel is expected to be the next generation flat panel display technology following the LCD, and is one of the most attention-paid technologies in the current flat panel display technology.
The color method of the OLED screen body is various, and the OLED color technology which is mature at present and is produced in a large amount is mainly an OLED evaporation technology, and the evaporation is carried out by adopting a traditional RGB strip arrangement mode. The best picture effect is the side-by-side (juxtaposition) mode. The side-by-side mode is that three sub-pixels (sub-Pixel) of red, green and blue (R, G, B) are arranged in the Pixel range, each sub-Pixel is quadrilateral and is provided with independent organic light-emitting components, the organic light-emitting components are formed on the array substrate at corresponding Pixel positions by utilizing a vapor deposition film forming technology through a high-definition metal mask (FINE METAL MASK, FMM), and the high-definition metal mask is commonly called a metal mask or a vapor deposition mask for short. The technical focus of fabricating high PPI (Pixel Per Inch) OLED display panels is on fine and mechanically stable FMMs and Pixel (sub-Pixel) arrangements.
Fig. 1 is a schematic diagram of 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, and each Pixel unit Pixel includes an R sub-Pixel area 101, a G sub-Pixel area 103 and a B sub-Pixel area 105, wherein the R sub-Pixel area 101 includes an R light emitting area 102 and an R non-light emitting area (not numbered), the G sub-Pixel area 103 includes a G light emitting area 104 and a G non-light emitting area (not numbered), and the B sub-Pixel area 105 includes a B light emitting area 106 and a B non-light emitting area (not numbered). The area of the R, G, B sub-pixels and the area of the light-emitting area shown in fig. 1 are respectively equal, and the R, G, B sub-pixels are arranged in a straight line. Specifically, in the light emitting region of each sub-pixel region, a cathode, an anode, and an electroluminescent layer (also referred to as an organic emission layer) is included, wherein the electroluminescent layer is located between the cathode and the anode for generating light of a predetermined color to realize display. In the fabrication of the display panel in the related art, it is generally necessary to use three vapor deposition processes 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 vapor deposited by using the FMM shown in fig. 2, and the FMM includes a shielding region 107 and a plurality of vapor deposition openings 108, where the shielding region between two adjacent vapor deposition openings 108 in the same column is called a bridge (bridge). In order to avoid the shielding effect on the sub-pixels during vapor deposition, a sufficient distance must be kept between the sub-pixels and the bridge, which leads to a reduction in the length of the sub-pixels, and affects the aperture ratio of each sub-pixel. The traditional RGB juxtaposed pixel arrangement mode can only reach 200-300 PPI at most, and the high-resolution display effect is difficult to realize. As the resolution of OLED display panels is increasing for users, this way of juxtaposing RGB pixels has not been able to meet the design requirements of high PPI products.
Fig. 3 is a schematic diagram of a pixel arrangement of another OLED display panel in the prior art. As shown in fig. 3, only the G sub-pixel is used for each pixel unit, and the R and B sub-pixels are shared with adjacent pixel units, for example, the R sub-pixel is shared by the pixel unit 201 and the pixel unit 202. In this way PPI of the display screen can be improved, however, in this arrangement, the R and B sub-pixels are shared by adjacent pixel units, and distortion may exist in the whole display effect, which is not true full color display.

In the pixel arrangement mode, each pixel unit (pixel) is composed of RGB three colors, full-color display in the true sense can be realized, meanwhile, the pixel units can be arranged more compactly, the pixel spacing is reduced, and the PPI is improved. In addition, when the first sub-pixel and the second sub-pixel are arranged in a column (row), the third sub-pixels of two adjacent pixel units on the same column (row) are arranged in a staggered manner, so that the difficulty of a mask manufacturing process and an evaporation process can be reduced.
The pixel structure and the OLED display panel comprising the pixel structure provided by the invention are further described in detail below with reference to the accompanying drawings. Advantages and features of the invention will become more apparent from the following description and from the claims. It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the invention.
Example 1
Fig. 4 is a schematic diagram illustrating a pixel arrangement of an OLED display panel according to a first embodiment of the invention. Wherein the X-direction is referred to as the row direction (lateral) and the Y-direction is referred to as the column direction (longitudinal). For simplicity, only a part of the OLED display panel is shown in the drawings, the number of pixels in the actual product is not limited thereto, and the number of pixel units may be changed according to the actual display requirement. The first row, the second row, the first column, the second column, etc. are all reference standards for illustrating the present invention, and do not refer to the rows and columns in the actual product.
As shown in fig. 4, the pixel structure of the OLED display panel includes a plurality of pixel units arranged in an array, each pixel unit includes a first sub-pixel 301, a second sub-pixel 303, and a third sub-pixel 305, the first sub-pixel 301 and the second sub-pixel 303 are arranged in a column, the third sub-pixel 305 is arranged in another column, a total dimension L1 of the first sub-pixel 301 and the second sub-pixel 303 along the column direction (i.e., a sum of dimensions of the first sub-pixel 301 and the second sub-pixel 303 along the column direction) is greater than a dimension L2 of the third sub-pixel 305 along the column direction, the arrangement structure of all pixel units in the same row is the same, and the arrangement structure of each pixel unit after being turned over (turned left and right by itself) along the row direction is the same as the arrangement structure of adjacent pixel units in the same column. In this way, the pixel units can be arranged more compactly, the pixel space is reduced, the PPI is improved, and each pixel unit is composed of RGB three colors, so that full-color display in the true sense can be realized.
Further, since the arrangement manner of the pixel units in the present invention is more compact, the total dimension of the pixel units along the row direction may be larger, so that the total dimension of the pixel units along the row direction (i.e., the maximum dimension of the pixel units along the row direction) is larger than the maximum dimension of the pixel units along the column direction (herein, the total dimension of the first sub-pixel 301 and the second sub-pixel 303 along the column direction), that is, so that L0 is larger than L1, for example, L0: l1=3:2, so that the 2 pixel units in the present embodiment can achieve the display effect of the conventional 3 pixel units, compared with the conventional square pixel unit (the ratio of the row direction size to the column direction size is 1:1). Of course, the specific proportional relation between L0 and L1 is not limited, and the ratio between the total dimension L0 of the pixel unit along the row direction and the maximum dimension L1 of the pixel unit along the column direction may be 2:1, 4:3, 5:4, etc.
Here, the pixel units of the first row and the first column are denoted as pixel units (1, 1), the pixel units of the first row and the second column are denoted as pixel units (1, 2), the pixel units of the second row and the first column are denoted as pixel units (2, 1), the pixel units of the second row and the second column are denoted as pixel units (2, 2), and so on. As shown in fig. 4, the arrangement structure of the pixel units (1, 3) in the third column of the first row after being turned 180 degrees is the same as the arrangement structure of the pixel units in the adjacent row in the same column, namely, the pixel units (2, 3) in the third column of the second row. Therefore, the adjacent two pixel units on the same column, for example, the pixel units (1, 3) and the third sub-pixels of the pixel units (2, 3) are staggered, i.e., the pixel units (1, 3) and the third sub-pixels of the pixel units (2, 3) are not arranged on a straight line, so that the vapor deposition openings on the vapor deposition mask (FMM) for forming the third sub-pixels are also staggered, and the difficulty of the vapor deposition mask manufacturing process and the vapor deposition process can be reduced.
Specifically, each subpixel includes a light emitting region (display region) and a non-light emitting region (non-display region), and the light emitting region of each subpixel includes a cathode, an anode, and an electroluminescent layer (organic emission layer) between the cathode and the anode for generating light of a predetermined color to realize display. Three vapor deposition processes are generally required to form electroluminescent layers of corresponding colors (e.g., red, green, or blue) in the light emitting regions of the pixel regions of the corresponding colors, respectively.
In this embodiment, the light emitting areas of the first sub-pixel 301, the second sub-pixel 303 and the third sub-pixel 305 may be arranged in a "delta" shape, an inverted delta "shape, a" delta "shape rotated 90 degrees to the left or a" delta "shape rotated 90 degrees to the right, or may be arranged in a substantially" delta "shape, an inverted delta" shape, a "delta" shape rotated 90 degrees to the left or a "delta" shape rotated 90 degrees to the right. In the arrangement structure shown in fig. 4, in the pixel units of the odd-numbered rows, the light emitting region 302 of the first sub-pixel 301, the light emitting region 304 of the second sub-pixel 303, and the light emitting region 306 of the third sub-pixel 305 are arranged in a "delta" shape rotated by 90 degrees to the right, that is, the first sub-pixel 301 and the second sub-pixel 303 are arranged on the left side, and the third sub-pixel 305 is arranged on the right side; in the pixel units of the even-numbered rows, the light emitting region 302 of the first sub-pixel 301, the light emitting region 304 of the second sub-pixel 303, and the light emitting region 306 of the third sub-pixel 305 are arranged in a "delta" shape rotated 90 degrees to the left, that is, the third sub-pixel 305 is arranged on the left side, and the first sub-pixel 301 and the second sub-pixel 303 are arranged on the right side. Further, the first sub-pixels 301 of all the pixel units in the same row are arranged on a straight line, and the second sub-pixels of all the pixel units in the same row are also arranged on a straight line.
In this embodiment, the first sub-pixel 301 is a red (R) sub-pixel, the second sub-pixel 303 is a green (G) sub-pixel, and the third sub-pixel 305 is a blue (B) sub-pixel; accordingly, the first subpixel 301 includes an R light emitting region 302 and an R non-light emitting region (not numbered in the drawing), and includes an organic emission layer for emitting red light; the second subpixel 303 includes a G light emitting region 304 and a G non-light emitting region (not numbered in the drawing), and includes an organic emission layer for emitting green light; the third subpixel 305 includes a B light emitting region 306 and a B non-light emitting region (not numbered in the figure), and includes an organic emission layer for emitting blue light. Since the light emitting efficiency of the B sub-pixel is generally the lowest, the required light emitting area is correspondingly larger, and thus the area of the third sub-pixel 305 is larger than the areas of the first sub-pixel 301 and the second sub-pixel 303.
In a preferred embodiment, the shapes and areas of the first sub-pixel 301 and the second sub-pixel 303 are equal, that is, the sub-pixels are distributed in a mirror symmetry manner, and in each pixel unit, the central line of the third sub-pixel 305 extending along the row direction coincides with the boundary line of the first sub-pixel 301 and the second sub-pixel 303, so that the pixel pitch (pitch) can be further reduced, the PPI of the display screen can be improved, the RGB sub-pixels are uniformly distributed, and a better display effect is achieved. Referring specifically to fig. 4, a center line 306' of the third sub-pixel 305 extending along the row direction (the center line 306' divides the third sub-pixel 305 into two parts and the center line 306' extends along the row direction) coincides with the boundary line of the first sub-pixel 301 and the second sub-pixel 303, and it should be noted that, since the first sub-pixel 301 and the second sub-pixel 302 in the same pixel unit share one side, the shared side is the boundary line of the first sub-pixel 301 and the second sub-pixel 302, but it should be understood that the "boundary" or "boundary line" herein is not limited to the "boundary" or "boundary line" of the entity, but may refer to the virtual "boundary" or "boundary line" between the two sub-pixels.
In this embodiment, the first sub-pixel 301 and the second sub-pixel 303 are rectangular, the third sub-pixel 305 is square, and the first sub-pixel 301 and the second sub-pixel 303 are arranged along the short side direction thereof, wherein the side length (height) of the light emitting region 306 of the third sub-pixel 305 is 2 times the short side length (height) of the light emitting region 302 of the first sub-pixel 301 and the short side length (height) of the light emitting region 304 of the second sub-pixel 303. It should be understood that the shapes of the first sub-pixel 301, the second sub-pixel 303, and the third sub-pixel 303 are not limited to a rectangle, but may be other quadrangles other than a rectangle, or one or any combination of polygons such as a triangle, pentagon, hexagon, octagon, and the like. Meanwhile, the areas of the first sub-pixel 301 and the second sub-pixel 303 may be unequal, and the area of the third sub-pixel 305 is not limited to 2 times the area of the first sub-pixel 301 or the second sub-pixel 303, and the shape and/or the area of each sub-pixel may be adjusted accordingly according to the color matching requirement.
Example two
Fig. 5 is a schematic diagram illustrating pixel arrangement of an OLED display panel according to a second embodiment of the invention. As shown in fig. 5, each pixel unit includes a first sub-pixel 301, a second sub-pixel 303, and a third sub-pixel 305, where the first sub-pixel 301 and the second sub-pixel 303 are arranged in one column, the third sub-pixel 305 is arranged in another column, the arrangement structure of all pixel units in the same row is the same, and the arrangement structure of each pixel unit after being flipped (flipped left and right) in the row direction is the same as the arrangement structure of the adjacent pixel units in the same column. For example, the arrangement structure of the pixel units (1, 1) in the first row and the first column turned 180 degrees in the row direction is the same as the arrangement structure of the adjacent pixel units in the same column, namely, the pixel units (2, 1) in the second row and the first column.
The difference between this embodiment and the first embodiment is that the OLED display panel shown in fig. 4 is turned horizontally by 180 degrees. Specifically, in the pixel units of the odd-numbered rows, the light emitting region 302 of the first sub-pixel 301, the light emitting region 304 of the second sub-pixel 303, and the light emitting region 306 of the third sub-pixel 305 are arranged in a "delta" shape rotated 90 degrees to the left, that is, the third sub-pixel 305 is arranged on the left side, and the first sub-pixel 301 and the second sub-pixel 303 are arranged on the right side; in the pixel units of the even-numbered rows, the light emitting region 302 of the first sub-pixel 301, the light emitting region 304 of the second sub-pixel 303, and the light emitting region 306 of the third sub-pixel 305 are arranged in a "delta" shape rotated 90 degrees to the right, that is, the first sub-pixel 301 and the second sub-pixel 303 are arranged on the left side, and the third sub-pixel 305 is arranged on the right side.
Example III
Fig. 6 is a schematic diagram illustrating a pixel arrangement of an OLED display panel according to a third embodiment of the present invention. As shown in fig. 6, the difference between the present embodiment and the first embodiment is that the first sub-pixels 301 of all the pixel units in the same row are not arranged in a straight line, and the second sub-pixels 303 of all the pixel units in the same row are not arranged in a straight line, but the first sub-pixels 301 and the second sub-pixels 303 of all the pixel units in the same row are arranged in a staggered manner. For example, the first sub-pixels 301 of the pixel units (1, 1) of the first row and the first column, the second sub-pixels 303 of the pixel units (1, 2) of the first row and the second column, and the first sub-pixels 301 of the pixel units (1, 3) of the first row and the third column are sequentially arranged on a straight line.
Example IV
Fig. 7 is a schematic diagram illustrating a pixel arrangement of an OLED display panel according to a fourth embodiment of the present invention. As shown in fig. 7, the difference between the present embodiment and the first embodiment is that the OLED display panel shown in fig. 4 is rotated by 90 degrees so that rows and columns are interchanged, and if the X direction is still referred to as a row direction (lateral direction) and the Y direction is referred to as a column direction (longitudinal direction), it is understood that the first sub-pixel 301 and the second sub-pixel 303 are arranged in one row, and the third sub-pixel 305 is arranged in another row, and the total dimension L3 of the first sub-pixel 301 and the second sub-pixel 303 along the row direction is greater than the dimension L4 of the third sub-pixel 305 along the row direction. The arrangement structure of the pixel units in the same column is the same, and the arrangement structure of each pixel unit after being turned over (turned over up and down) along the column direction is the same as the arrangement structure of the adjacent pixel units in the same row. For example, the arrangement structure of the pixel units (1, 1) in the first row and the first column turned 180 degrees in the column direction at the center point thereof is the same as the arrangement structure of the pixel units in the adjacent column in the same row, i.e., the pixel units (1, 2) in the first row and the second column.
Further, since the arrangement manner of the pixel units in the present invention is more compact, the total dimension of the pixel units along the column direction may be larger, so that the total dimension of the pixel units along the column direction is larger than the maximum dimension of the pixel units along the row direction (herein, the total dimension of the first sub-pixel 301 and the second sub-pixel 303 along the row direction), that is, L5 is larger than L3, for example, L5: l3=3:2, so that the 2 pixel units in the present embodiment can achieve the display effect of the conventional 3 pixel units, compared with the conventional square pixel unit. Likewise, the specific proportional relationship between L5 and L3 is not limited, and the ratio between the total dimension L5 of the pixel unit along the column direction and the maximum dimension L3 of the pixel unit along the row direction may be 2:1, 4:3, 5:4, etc.
Example five
The present embodiment provides an OLED display panel, which can employ the pixel structure described in any one of the first to fourth embodiments.
It should be noted that, in the present description, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different manner from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other.
The pixel structure and the OLED display panel including the pixel structure according to the present invention are described in detail in the above embodiments, but it should be understood that the above description is only for describing the preferred embodiments of the present invention, and not for limiting the scope of the present invention, and any changes and modifications made by those skilled in the art according to the above disclosure are all within the scope of the claims.
