Description

Display device

Technical Field

The present invention relates to a display, and more particularly, to a display with a free-form design.

Background

With the progress of technology, the technology of displays is also continuously developed. Light, thin, short, and small Flat Panel Displays (FPDs) are gradually replacing the traditional thick Cathode Ray Tube (CRT) Display. For example, flat panel displays that have been developed may include Liquid Crystal Displays (LCDs), Organic Light Emitting Displays (OLEDs), field emission display devices (FEDs), Electrophoretic Displays (EDs), and the like.

Generally, the shape of the flat panel display is rectangular or square, which is difficult to be applied to displays with various shapes, such as instrument panels, smart watches, or wearable devices in automobiles. Therefore, displays with free-form design have been the subject of active research by developers. However, for the current display with free-form design, the edge still has severe jaggy (Zag issue) or Rainbow texture (Rainbow issue), which causes the image quality of the display to be degraded.

Disclosure of Invention

At least one embodiment of the present invention provides a display having good image quality.

The display of at least one embodiment of the present invention includes a peripheral shading pattern, a plurality of peripheral pixels, and a plurality of non-peripheral pixels. The plurality of peripheral pixels partially overlap the peripheral light shielding pattern. The plurality of non-peripheral pixels are not overlapped with the peripheral light shielding pattern. Each peripheral pixel includes a first sub-pixel, a second sub-pixel, and a third sub-pixel. The first sub-pixel includes a first sub-pixel electrode and a first composite filter layer. The first composite filter layer includes a first red filter pattern, a first green filter pattern, and a first blue filter pattern. The second sub-pixel comprises a second sub-pixel electrode and a second composite filter layer. The second composite filter layer includes a second red filter pattern, a second green filter pattern, and a second blue filter pattern. The third sub-pixel includes a third sub-pixel electrode and a third composite filter layer. The third composite filter layer includes a third red filter pattern, a third green filter pattern, and a third blue filter pattern. In the area outside the peripheral shading pattern, the total area of the first red filter pattern, the second red filter pattern and the third red filter pattern is A for a single peripheral pixel; the area sum of the first green light filtering pattern, the second green light filtering pattern and the third green light filtering pattern is B; the area sum of the first blue filter pattern, the second blue filter pattern and the third blue filter pattern is C, and A: b: c is about 1: 1: 1.

a display of at least another embodiment of the present invention includes a peripheral light shielding pattern, a plurality of peripheral pixels, and a plurality of non-peripheral pixels. The plurality of peripheral pixels partially overlap the peripheral light shielding pattern. The plurality of non-peripheral pixels are not overlapped with the peripheral light shielding pattern. Each peripheral pixel includes a first sub-pixel, a second sub-pixel, and a third sub-pixel. The first sub-pixel, the second sub-pixel and the third sub-pixel respectively comprise a pixel electrode and a composite filter layer. The composite filter layer includes red, green, and blue filter patterns. One of the non-peripheral pixels includes a fourth sub-pixel and a first sub-pixel of one of the peripheral pixels belongs to the same first color sub-pixel row, and the area of the first color filter pattern of the first sub-pixel is larger than the area of any one of the other two filter patterns of the first sub-pixel.

In view of the above, the display provided by at least one embodiment of the invention can make the overall ratio of the red filter pattern, the green filter pattern and the blue filter pattern in the peripheral pixels approximately the same, so that the display can have good image quality.

In order to make the aforementioned and other features and advantages of the invention more comprehensible, embodiments accompanied with figures are described in detail below.

FIG. 1A is a top view of a display according to an embodiment of the invention.

Referring to fig. 1A, a display 100 includes a peripheral shading pattern 102, a plurality of peripheral pixels 104, and a plurality of non-peripheral pixels 106. The peripheral pixels 104 partially overlap the peripheral light-shielding pattern 102. The non-peripheral pixels 106 do not overlap the peripheral light-shielding pattern 102. In the present embodiment, the display 100 may be a display with a free-form design (i.e., the display 100 may be a non-rectangular shape, which may also be referred to as a heterogeneous display). That is, the shape of the display 100 at the edge of the display area (e.g., the area other than the peripheral pixels 106 and the partial area where the peripheral pixels 104 do not overlap the peripheral shading pattern 102) may be a non-rectangular shape (e.g., an arc shape). In some embodiments, the display 100 with free-form design may employ the peripheral shading pattern 102 with a non-rectangular outline (e.g., including an arc outline, a circular outline or a triangular outline) to avoid the jagged edge outline of the display area, thereby providing the display 100 with good image quality. The material of the peripheral light-shielding pattern 102 may be an opaque material, such as a material suitable for a black matrix (black matrix).

Each peripheral pixel 104 may include a first sub-pixel PX1, a second sub-pixel PX2, a third sub-pixel PX3, a data line DL, and a scan line SL. In some embodiments, the first sub-pixel PX1, the second sub-pixel PX2, and the third sub-pixel PX3 may be arranged along a row direction (e.g., the first direction D1).

The first sub-pixel PX1 may include a first sub-pixel electrode PE1, a first composite filter layer CF1, and an active device TFT electrically connected to the first sub-pixel electrode PE1, and the active device TFT is electrically connected to the corresponding scan line SL and data line DL. For example, the gate, the source and the drain of the active device TFT may be electrically connected to the scan line SL, the data line DL and the first sub-pixel electrode PE1, respectively.

The first composite filter layer CF1 may include first red filter patterns R1, first green filter patterns G1, and first blue filter patterns B1. In the present embodiment, the first red filter pattern R1, the first green filter pattern G1, and the first blue filter pattern B1 may be arranged along a row direction (e.g., the first direction D1). For example, as shown in fig. 1A, the arrangement of the red filter patterns R1, the green filter patterns G1 and the blue filter patterns B1 in the first direction D1 in the first composite filter layer CF1 may be the first red filter patterns R1, the first green filter patterns G1 and the first blue filter patterns B1 in sequence. The material of the first composite filter layer CF1 is, for example, a color resist, an organic layer or an inorganic layer mixed with quantum dots or quantum rods, or a combination thereof, or other suitable color conversion materials. In some embodiments, the first composite filter layer CF1 may be disposed on the first sub-pixel electrode PE 1.

The second sub-pixel PX2 may include a second sub-pixel electrode PE2, a second composite filter layer CF2, and an active device TFT electrically connected to the second sub-pixel electrode PE2, and the active device TFT is electrically connected to the corresponding scan line SL and data line DL. For example, the gate, the source and the drain of the active device TFT may be electrically connected to the scan line SL, the data line DL and the second sub-pixel electrode PE2, respectively.

The second composite filter layer CF2 may include second red filter patterns R2, second green filter patterns G2, and second blue filter patterns B2. In the present embodiment, the second red filter pattern R2, the second green filter pattern G2, and the second blue filter pattern B2 may be arranged along the first direction D1. For example, as shown in fig. 1A, in the second composite filter layer CF2, the second blue filter pattern B2, the second green filter pattern G2 and the second red filter pattern R2 are sequentially arranged in the first direction D1. The material of the second composite filter layer CF2 is, for example, a color resist, an organic layer or an inorganic layer mixed with quantum dots or quantum rods, or a combination thereof, or other suitable color conversion materials. In some embodiments, the second composite filter layer CF2 may be disposed on the second sub-pixel electrode PE 2.

The third sub-pixel PX3 may include a third sub-pixel electrode PE3, a third composite filter layer CF3, and an active device TFT electrically connected to the third sub-pixel electrode PE3, and the active device TFT is electrically connected to the corresponding scan line SL and data line DL. For example, the gate, the source and the drain of the active device TFT may be electrically connected to the scan line SL, the data line DL and the third sub-pixel electrode PE3, respectively.

The third composite filter layer CF3 may include a third red filter pattern R3, a third green filter pattern G3, and a third blue filter pattern B3. In the present embodiment, the third red filter pattern R3, the third green filter pattern G3, and the third blue filter pattern B3 may be arranged along the first direction D1. For example, as shown in fig. 1A, in the third composite filter layer CF3, the third red filter pattern R3, the third red filter pattern G3 and the third blue filter pattern B3 are sequentially arranged in the first direction D1. The material of the third composite filter layer CF3 is, for example, a color resist, an organic layer or an inorganic layer mixed with quantum dots or quantum rods, or a combination thereof, or other suitable color conversion materials. In some embodiments, the third composite filter layer CF3 may be disposed on the third sub-pixel electrode PE 3.

In the present embodiment, in the region other than the peripheral light-shielding pattern 102, for a single peripheral pixel 104, the total area of the first red filter pattern R1, the second red filter pattern R2, and the third red filter pattern R3 is a; the areas of the first, second, and third green filter patterns G1, G2, and G3 are combined to B; and the area of the first, second, and third blue filter patterns B1, B2, and B3 is collectively C, and a: b: c is about 1: 1: 1. in this way, under the condition that the areas of the red, green and blue filter patterns of the peripheral pixels 104 that are not overlapped with the peripheral shading pattern 102 are substantially the same (i.e. the shielding ratios of the red, green and blue filter patterns by the peripheral shading pattern 102 are substantially the same), the problem of rainbow stripes caused by color mismatch of the peripheral pixels 104 of the display 100 can be improved, and the image quality of the display 100 can be further improved.

In the present embodiment, the area of the first red filter pattern R1, the area of the first green filter pattern G1, and the area of the first blue filter pattern B1 are about equal; the area of the second red filter pattern R2, the area of the second green filter pattern G2, and the area of the second blue filter pattern B2 are about equal; and the area of the third red filter pattern R3, the area of the third green filter pattern G3, and the area of the third blue filter pattern B3 are about equal. In this way, in the present embodiment, the first sub-pixel PX1, the second sub-pixel PX2, and the third sub-pixel PX3 of the peripheral pixel 104 are all white sub-pixels, so that the display 100 does not have a rainbow effect caused by color mismatch in the peripheral pixel 104, thereby improving the image quality of the display 100.

One of the non-peripheral pixels 106 may include a fourth sub-pixel PX4, a fifth sub-pixel PX5, a sixth sub-pixel PX6, a data line DL, and a scan line SL. The fourth to sixth sub-pixels PX4, PX5, PX6 may respectively include a sub-pixel electrode PE4, a color filter pattern (e.g., a red filter pattern r, a green filter pattern g, or a blue filter pattern b), and an active device TFT connected to the pixel electrode PE4, and the active device TFT is electrically connected to the corresponding scan line SL and data line DL. In the present embodiment, the fourth sub-pixel PX4, the fifth sub-pixel PX5, and the sixth sub-pixel PX6 may be arranged along the first direction D1. In some embodiments, the color filter pattern of the non-peripheral pixels 106 may be disposed on the sub-pixel electrode PE 4.

In the present embodiment, the fourth sub-pixel PX4, the fifth sub-pixel PX5, and the sixth sub-pixel PX6 may include a red filter pattern r, a green filter pattern g, and a blue filter pattern b, respectively. In other words, the fourth sub-pixel PX4, the fifth sub-pixel PX5, and the sixth sub-pixel PX6 may be a red sub-pixel, a green sub-pixel, and a blue sub-pixel, respectively.

In some embodiments, the display 100 may include a liquid crystal layer LC. The liquid crystal layer LC may overlap the non-peripheral pixels 106 and the first to third sub-pixel electrodes PE1 to PE 3. The liquid crystal layer LC may include liquid crystal molecules rotated or switched by a horizontal electric field (in-plane-switching) or liquid crystal molecules rotated or switched by a vertical electric field (vertical-switching), but the present invention is not limited thereto. In some embodiments, the liquid crystal layer LC may be disposed between the pixel electrodes PE1 to PE4 and the color filter pattern. In some embodiments, the liquid crystal layer LC may be disposed on the pixel electrodes PE1 to PE4 and the color filter pattern. The color filter patterns may include first to third red filter patterns R1 to R3, first to third green filter patterns G1 to G3, or first to third blue filter patterns B1 to B3 of the peripheral pixels 104, and red filter patterns R, green filter patterns G, or blue filter patterns B of the non-peripheral pixels 106.

Referring to fig. 1B, fig. 1C, fig. 1D and fig. 1E, fig. 1B is a cross-sectional view corresponding to a section line I-I 'in fig. 1A, fig. 1C is a cross-sectional view corresponding to a section line II-II' in fig. 1A, fig. 1D is a cross-sectional view corresponding to a section line III-III 'in fig. 1A, and fig. 1E is a cross-sectional view corresponding to a section line IV-IV' in fig. 1A. In the present embodiment, the Color Filter is integrated in a Color Filter on Array (COA) type vertical electric field liquid crystal display (lcd), but the invention is not limited thereto.

Referring to fig. 1A and fig. 1B, the display 100 further includes a first substrate 110, a first insulating layer 112, a second insulating layer 114, a third insulating layer 116, a fourth insulating layer 118, a second substrate 120, and a common electrode 122. In the third sub-pixel electrode PE3 of the peripheral pixel 104, the first insulating layer 112 is positioned between the data line DL and the first substrate 110, the data line DL is positioned between the second insulating layer 114 and the first insulating layer 112, the third insulating layer 116 is positioned on the second insulating layer 114, the third red filter pattern R3, the third green filter pattern G3 and the third blue filter pattern B3 are all positioned between the fourth insulating layer 118 and the third insulating layer 116, the third sub-pixel electrode PE3 is positioned on the fourth insulating layer 118, and the liquid crystal layer LC is positioned between the third sub-pixel electrode PE3 and the common electrode 122. In the third sub-pixel electrode PE3 of the peripheral pixel 104 of the embodiment, the third red filter pattern R3 and the third blue filter pattern B3 respectively protrude from opposite sides of the third sub-pixel electrode PE3 in the first direction D1, for example, an outermost figure contour of the third composite filter layer CF3 projected on the first substrate 110 in the projection direction protrudes from a figure contour of the third sub-pixel electrode PE3 projected on the first substrate 110 in the projection direction. With continued reference to fig. 1A and 1C, the scan line SL is located between the first substrate 110 and the first insulating layer 112, and in the third sub-pixel electrode PE3 of the peripheral pixel 104 of the present embodiment, the third blue filter pattern B3 protrudes outward from the other two opposite sides of the third sub-pixel electrode PE3 in the second direction D2, and similarly, the third red filter pattern R3 and the third green filter pattern G3 both protrude outward from the other two opposite sides of the third sub-pixel electrode PE3 in the second direction D2. In the present embodiment, the peripheral light-shielding pattern 102 is disposed between the second substrate 120 and the common electrode 122.

Referring to fig. 1A, fig. 1D and fig. 1E, the fourth sub-pixel PX4 in the non-peripheral pixel 106 and the first sub-pixel PX1 in the peripheral pixel 104 of the display 100 belong to the same first color sub-pixel row, which is, for example, a red sub-pixel row. In the fourth sub-pixel PX4 in the non-peripheral pixel 106, the red filter pattern r is located between the third insulating layer 116 and the fourth insulating layer 118, and protrudes outward from the sub-pixel electrode PE4 in both the first direction D1 and the second direction D2, but the invention is not limited thereto.

The above description of fig. 1B to fig. 1E takes the third sub-pixel PX3 in the peripheral pixel 104 and the fourth sub-pixel PX4 in the non-peripheral pixel 106 as an example, but those skilled in the art can understand the structure and the corresponding relationship of the elements in each sub-pixel according to the above description, and therefore the description is not repeated.

Fig. 2 is a top view of a display according to another embodiment of the invention, wherein the display 200 is substantially the same as the display 100, except that the areas of one of the red filter patterns (e.g., the first to third red filter patterns R1, R2, R3), the green filter patterns (e.g., the first to third green filter patterns G1, G2, G3) and the blue filter patterns (e.g., the first to third blue filter patterns B1, B2, B3) of the sub-pixels (e.g., the first to third sub-pixels PX1, PX2, PX3) of the peripheral pixel 204 are larger than those of the other sub-pixels, so that the same or similar elements use the same or similar reference numerals, and the connection relationships, materials and processes of the remaining components have been described in detail in the foregoing text, and thus will not be repeated herein.

Referring to fig. 2, in some embodiments, one of the first red filter pattern R1, the first green filter pattern G1 and the first blue filter pattern B1 of the first sub-pixel PX1 may have an area larger than the other two. For example, the area of the first red filter pattern R1 may be greater than the area of the first green filter pattern G1 and the area of the first blue filter pattern B1, so that the first sub-pixel PX1 can emit red light (i.e., the first sub-pixel PX1 may be a red sub-pixel). In the present embodiment, the first red filter pattern R1 may be divided into two portions, one portion of the first red filter pattern R1 may be aligned with the first green filter pattern G1 and the first blue filter pattern B1 along the row direction, and the other portion of the first red filter pattern R1 may be disposed in the first composite filter layer CF1 adjacent to the non-peripheral pixels 106.

In this embodiment, the fourth sub-pixel PX4 in the non-peripheral pixel 106 and the first sub-pixel PX1 in the peripheral pixel 204 belong to the same color sub-pixel column, where the same color sub-pixel column is a red sub-pixel column, and the first red filter pattern R1 in the first sub-pixel PX1 is, for example, configured in an L-shape, but not limited thereto. The area of the first red filter pattern R1 is greater than that of the first green filter pattern G1 and greater than that of the first blue filter pattern B1.

In other embodiments, one of the second red filter pattern R2, the second green filter pattern G2 and the second blue filter pattern B2 of the second sub-pixel PX2 may have an area larger than the other two. For example, the area of the second green filter pattern G2 may be greater than the area of the second red filter pattern R2 and the area of the second blue filter pattern B2, so that the second sub-pixel PX2 can emit green light (i.e., the second sub-pixel PX2 may be a green sub-pixel). In the present embodiment, the second green filter pattern G2 may be divided into two portions, one portion of the second green filter pattern G2 and the second red filter pattern R2 and the second blue filter pattern B2 are arranged along the row direction, and the other portion of the second green filter pattern G2 may be disposed in the second composite filter layer CF2 adjacent to the non-peripheral pixels 106.

In the present embodiment, the fifth sub-pixel PX5 in the non-peripheral pixel 106 and the second sub-pixel PX2 in the peripheral pixel 204 belong to the same color sub-pixel column, where the same color sub-pixel column is a green sub-pixel column, and the second green filter pattern G2 in the second sub-pixel PX2 is, for example, configured in a T shape, but not limited thereto. The area of the second green filter pattern G2 is greater than the area of the second blue filter pattern B2 and greater than the area of the second red filter pattern R2.

In other embodiments, one of the third red, third green and third blue filter patterns R3, G3 and B3 of the third sub-pixel PX3 may also have an area larger than the other two. For example, the area of the third blue filter pattern B3 may be greater than the area of the third red filter pattern R3 and the area of the third blue filter pattern B3, so that the third sub-pixel PX3 can emit blue light (i.e., the third sub-pixel PX3 may be a blue sub-pixel). In the present embodiment, the third blue filter pattern B3 may be divided into two portions, one portion of the third blue filter pattern B3 and the third red filter pattern R3 and the third green filter pattern G3 are arranged along the row direction, and the other portion of the third blue filter pattern B3 may be disposed in the third composite filter layer CF3 adjacent to the non-peripheral pixels 106.

In this embodiment, the sixth sub-pixel PX6 in the non-peripheral pixel 106 and the third sub-pixel PX3 in the peripheral pixel 204 belong to the same color sub-pixel column, where the same color sub-pixel column is a blue sub-pixel column, and the third blue filter pattern B3 in the third sub-pixel PX3 is, for example, configured in an L-shape, but not limited thereto. The area of the third blue filter pattern B3 is greater than the area of the third red filter pattern R3 and greater than the area of the third green filter pattern G3.

In the present embodiment, the first sub-pixel PX1, the second sub-pixel PX2, and the third sub-pixel PX3 may be a red sub-pixel, a green sub-pixel, and a blue sub-pixel, respectively, and under the condition that the areas of the red, green, and blue filter patterns of the single peripheral pixel 204 that is not overlapped with the peripheral light-shielding pattern 102 are substantially the same (i.e., the shielding ratios of the red, green, and blue filter patterns by the peripheral light-shielding pattern 102 are substantially the same), the colors of the display 200 in the peripheral pixel 204 can be matched, so as to improve the rainbow interference, and further improve the image quality of the display 200.

In some embodiments, in a region other than the peripheral light-shielding pattern 102, the area of the first red filter pattern R1 may be larger than the area of the first green filter pattern G1 and the area of the first blue filter pattern B1 for a single peripheral pixel 204. In other embodiments, in the region outside the peripheral light-shielding pattern 102, the area of the second green filter pattern G2 may be larger than the area of the second red filter pattern R2 and the area of the second blue filter pattern B2 for a single peripheral pixel 204. In other embodiments, in the region outside the peripheral light-shielding pattern 102, the area of the third blue filter pattern B3 may be larger than the area of the third red filter pattern R3 and the area of the third green filter pattern G3 for a single peripheral pixel 204.

In some embodiments, one of the non-peripheral pixels 106 may include the fourth sub-pixel PX4, and the fourth sub-pixel PX4 and the first sub-pixel PX1 of one of the peripheral pixels 204 belong to the same red sub-pixel row (as shown in fig. 2), which may enable the display 200 to reduce the problem of red color shift, so as to further improve the image quality of the display 200.

In other embodiments, one of the non-peripheral pixels 106 may also include the fifth sub-pixel PX5, and the fifth sub-pixel PX5 and the second sub-pixel PX2 of one of the peripheral pixels 204 belong to the same green sub-pixel row (as shown in fig. 2), so that the display 200 can reduce the problem of green color shift, and further improve the image quality of the display 200.

In other embodiments, one of the non-peripheral pixels 106 may include the sixth sub-pixel PX6, and the sixth sub-pixel PX6 and the third sub-pixel PX3 of one of the peripheral pixels 204 belong to the same blue sub-pixel column (as shown in fig. 2), which may enable the display 200 to reduce the problem of blue color shift, so as to further improve the image quality of the display 200.

In the present embodiment, the red sub-pixel row, the green sub-pixel row and the blue sub-pixel row are sequentially arranged along the first direction D1.

Fig. 3 is a top view of a display device according to another embodiment of the invention, wherein the display device 300 is substantially the same as the display device 200, except that the first to third sub-pixels PX 1-PX 3 in the peripheral pixel 304 are arranged along the first direction D1, the first red filter pattern R1, the first green filter pattern G1 and the first blue filter pattern B1 are arranged along the second direction D2, the same or similar elements are given the same or similar reference numerals, and the connection relationship, materials and processes of the remaining components have been described in the foregoing, and thus will not be repeated in detail.

Referring to fig. 3, the first to third sub-pixels PX 1-PX 3 of the peripheral pixel 304 of the display 300 may be arranged along a first direction D1, and the first red filter pattern R1, the first green filter pattern G1 and the first blue filter pattern B1 of the first sub-pixel PX1 may be arranged along a second direction D2, wherein the first direction D1 is substantially perpendicular to the second direction D2. For example, the red, green and blue filter patterns in the first composite filter layer CF1 may be arranged in a row direction (e.g., a direction away from the non-peripheral pixels 106) as a first red filter pattern R1, a first blue filter pattern B1, a first green filter pattern G1 and a first red filter pattern R1. The first blue filter pattern B1, the first green filter pattern G1, and the first red filter pattern R1 are illustrated as rectangles, but not limited thereto.

In some embodiments, the second red filter pattern R2, the second green filter pattern G2, and the second blue filter pattern B2 of the second sub-pixel PX2 may also be arranged along the second direction D2. For example, the red, green and blue filter patterns in the second composite filter layer CF2 may be arranged in a row direction (e.g., a direction away from the non-peripheral pixels 106) to be a second green filter pattern G2, a second red filter pattern R2, a second green filter pattern G2 and a second blue filter pattern B2 in sequence. The second red filter pattern R2, the second green filter pattern G2, and the second blue filter pattern B2 are illustrated as rectangles, but not limited thereto.

In other embodiments, the third red filter pattern R3, the third green filter pattern G3, and the third blue filter pattern B3 of the third sub-pixel PX3 may be further arranged along the second direction D2. For example, the red, green and blue filter patterns in the third composite filter layer CF3 may be arranged in a row direction (e.g., a direction away from the non-peripheral pixels 106) to be a third blue filter pattern B3, a third blue filter pattern B3, a third green filter pattern G3 and a third red filter pattern R3 in sequence. The third blue filter pattern B3, the third green filter pattern G3, and the third red filter pattern R3 are illustrated as rectangles, but not limited thereto.

In the present embodiment, the first sub-pixel PX1, the second sub-pixel PX2, and the third sub-pixel PX3 may be a red sub-pixel, a green sub-pixel, and a blue sub-pixel, respectively, and under the condition that the areas of the red, green, and blue filter patterns of the single peripheral pixel 304 that is not overlapped with the peripheral light-shielding pattern 102 are substantially the same (i.e., the shielding ratios of the red, green, and blue filter patterns by the peripheral light-shielding pattern 102 are substantially the same), the colors of the display 300 in the peripheral pixel 304 can be matched, so as to improve the rainbow interference, and further improve the image quality of the display 300.

Fig. 4 is a top view of a display 400 according to still another embodiment of the invention, wherein the display 400 is substantially the same as the display 300, except that the shapes of the second sub-pixel PX2, the third sub-pixel PX3 and the peripheral light shielding pattern 402 are different, so the same or similar elements have the same or similar reference numerals, and the connection relationship, materials and processes of the remaining components have been described in detail in the foregoing, and therefore, are not repeated herein.

The second green filter pattern G2 in the second sub-pixel PX2 in the present embodiment is, for example, configured in a T-shape, the second red filter pattern R2 and the second blue filter pattern B2 are respectively located in two concave portions of the T-shape, the green filter pattern G2 in the second composite filter layer CF2 may be divided into two portions, one portion of the green filter pattern G2 is aligned with the second red filter pattern R2 and the second blue filter pattern B2 along the first direction D1, and the other portion of the green filter pattern G2 is disposed in the second composite filter layer CF2 adjacent to the non-peripheral pixel 106. The third blue filter pattern B3, the third red filter pattern R3, the third green filter pattern G3 and the third blue filter pattern B3 in the third sub-pixel PX3 in the present embodiment are sequentially arranged in a column direction (e.g., a direction away from the non-peripheral pixel 106).

In the present embodiment, the first sub-pixel PX1, the second sub-pixel PX2, and the third sub-pixel PX3 may be a red sub-pixel, a green sub-pixel, and a blue sub-pixel, respectively, and under the condition that the areas of the red, green, and blue filter patterns of the single peripheral pixel 404 that is not overlapped with the peripheral light-shielding pattern 402 are substantially the same (i.e., the shielding ratios of the red, green, and blue filter patterns by the peripheral light-shielding pattern 402 are substantially the same), the colors of the display 400 and the peripheral pixel 404 can be matched to improve the rainbow interference, thereby improving the image quality of the display 400.

Fig. 5 is a top view of a display according to another embodiment of the invention, in which the display 500 is substantially the same as the display 300, except that the patterns of a portion of the first to third red filter patterns R1-R3, a portion of the first to third green filter patterns G1-G3, and a portion of the first to third blue filter patterns B1-B3 are non-rectangular patterns, so the same or similar elements are denoted by the same or similar reference numerals, and the connection relationship, materials, and processes of the remaining components have been described in detail in the foregoing, and thus will not be repeated herein.

Referring to fig. 5, the patterns of a portion of the first to third red filter patterns R1 to R3, a portion of the first to third green filter patterns G1 to G3, and a portion of the first to third blue filter patterns B1 to B3 in the first to third composite filter layers CF3 are non-rectangular patterns (e.g., triangular patterns). In the present embodiment, the first sub-pixel PX1, the second sub-pixel PX2, and the third sub-pixel PX3 may be a red sub-pixel, a green sub-pixel, and a blue sub-pixel, respectively, and under the condition that the areas of the red, green, and blue filter patterns of the peripheral pixel 504 that are not overlapped with the peripheral light-shielding pattern 102 are substantially the same (i.e., the shielding ratios of the red, green, and blue filter patterns by the peripheral light-shielding pattern 102 are substantially the same), the colors of the display 500 at the peripheral pixel 504 can be matched to improve the rainbow interference, thereby improving the image quality of the display 500.

As described above, in the display according to an embodiment of the invention, the overall ratio of the red filter pattern, the green filter pattern and the blue filter pattern in the peripheral pixels is approximately the same, so that the display has good image quality.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
