In order to improve product practicality while taking into account the aesthetic appearance, non-rectangular display devices are commonly used in wearable devices and automotive devices. The non-rectangular display device can be realized by using a frame to cover part of the rectangular panel. By adjusting the hollow area of the frame, the active area of the non-rectangular display device can take on various shapes. However, in this approach, the pixels at the edge of the active area will be blocked by the border and cannot be fully exposed, causing color aberration at the edge of the active area. For example, the border may partially block the blue sub-pixels in some pixels. This gives the edge of the active area a yellowish tint.

Non-rectangular display devices can also be implemented by arranging pixels into various shapes. In this approach, each pixel can be fully exposed without being blocked by the border, but users will observe an obvious jagged shape at the edge of the active area.

The embodiments of this disclosure document will be described below with reference to relevant drawings. In the drawings, the same reference numbers represent the same or similar elements or process flows.

Figure 1 is a simplified functional block diagram of a display device 100 according to an embodiment of this disclosure document. The display device 100 includes a plurality of ordinary pixels 110 , a plurality of auxiliary pixels 120 , a frame 130 , a driving chip 140 and a connection line 150 . The frame 130 is used to define the non-rectangular active area AA of the display device 100 . The active area AA refers to the area where the display device 100 provides images. The ordinary pixel 110 and the auxiliary pixel 120 are distributed in the active area AA, and the auxiliary pixel 120 is generally arranged around the ordinary pixel 110, that is, the auxiliary pixel 120 is located between the ordinary pixel 110 and the border 130, but it does not need to be completely Surround normal pixels by 110. The driving chip 140 is coupled to the ordinary pixel 110 and the auxiliary pixel 120 through the connection line 150, and is used to provide various display driving signals to the ordinary pixel 110 and the auxiliary pixel 120. To keep the drawing simple, other components and connection relationships in the display device 100 are not shown in Figure 1 .

Figure 2A is an enlarged schematic diagram of the area Bo in Figure 1. As can be seen from Figure 2A, each ordinary pixel 110 (the one not filled with dots) includes three sub-pixels 112 (labeled "R", "G" and "B" respectively) of red, green and blue. ), but this disclosure document is not limited to this. In some embodiments, each ordinary pixel 110 includes a plurality of sub-pixels 112 with different colors, and each auxiliary pixel 120 (filled with dots) includes a plurality of sub-pixels 122, and these sub-pixels 122 include 122 sub-pixels of the same color. In some embodiments, the number of sub-pixels 122 in the auxiliary pixel 120 is greater than or equal to the number of sub-pixels 112 in the ordinary pixel 110 . The colors of the sub-pixels 122 are arranged in sequence according to a fixed rule (such as red, green and blue). For example, taking Figure 2A as an example, if the auxiliary pixel 120 has five sub-pixels 122 (for example, the auxiliary pixel 120 in the first column from the top of Figure 2A), these five sub-pixels 122 are driven by the active Area AA is arranged horizontally toward the border 130 inside, and its colors are red, green, blue, red and green, and so on. The sub-pixels 122 with repeated colors in the auxiliary pixel 120 are used to fill the active area AA as much as possible to reduce the distance between the auxiliary pixel 120 and the frame 130, thereby improving the boundary smoothness of the image displayed by the display device 100. .

As shown in FIG. 2A , the sub-pixels 112 and 122 include a light-emitting area EM, and a light-emitting element is provided in the light-emitting area EM. The area other than the light-emitting area EM of the sub-pixel 112 and the sub-pixel 122 may be provided with a light-emitting element. Crystal driver circuit. The ordinary pixel 110, the auxiliary pixel 120 and the frame 130 are arranged on a substrate (not shown, such as a glass substrate) of the display device 100, and the vertical projection of the plurality of light-emitting areas EM in the auxiliary pixel 120 on the substrate (it can be understood that The projections in the direction perpendicular to the plane of the drawing 2A) do not overlap with the vertical projections of the frame 130 on the substrate. In this way, the light of various colors in the auxiliary pixel 120 will not be blocked by the frame 130, so no color aberration will occur at the boundary of the active area AA.

In some embodiments, the ordinary pixel 110 and the auxiliary pixel 120 are light-emitting diode pixel circuits, that is, the light-emitting elements in the light-emitting area EM are implemented with light-emitting diodes. The aforementioned light-emitting diode may be an organic light-emitting diode (OLED) or a micro-light emitting diode (Micro LED). The light-emitting diodes have the advantage of being small in size, and therefore can be arranged close to the edge of the frame 130 without being blocked by the frame 130 , which helps to improve the smoothness of the boundary of the image displayed by the display device 100 .

The ordinary pixel 110 and the auxiliary pixel 120 in Figure 2A are only examples, and various suitable arrangements of the ordinary pixel 110 and the auxiliary pixel 120 are within the scope of this disclosure document. For example, the ordinary pixels 110 and the auxiliary pixels 120 may be arranged in four primary colors as shown in Figure 2B or in a diamond arrangement (Pentile) as shown in Figure 2C. As shown in Figure 2B, in some embodiments of the four primary color arrangement, each ordinary pixel 110 (not filled with dots) includes red, green, blue and yellow sub-pixels 112 (respectively represented by "R", "G", "B" and "Y"), and each auxiliary pixel 120 (filled with dots) includes more than four sub-pixels 122, and there are colors in these sub-pixels 122 The same sub-pixel 122. As shown in Figure 2C, in some embodiments of the diamond arrangement, each ordinary pixel 110 (not filled with dots) includes red, green and blue sub-pixels 112 (respectively represented by "R") with different colors. , "G" and "B"), and each auxiliary pixel 120 (filled with dots) includes more than three sub-pixels 122, and there are sub-pixels 122 of the same color among these sub-pixels 122. In some embodiments, as shown in Figures 2A to 2C, the display device 100 also includes a plurality of dummy pixels 160. The light-emitting areas of these dummy pixels 160 are completely covered by the frame 130, so the dummy pixels 160 It will not cause chromatic aberration at the boundary of active area AA.

When the display device 100 is used to drive the auxiliary pixel 120 to generate light of a certain color with a target brightness, the display device 100 will allocate the target brightness to the color according to the number of sub-pixels 122 of the color in the auxiliary pixel 120 . The brightness of the sub-pixels 122 is adjusted so that the sum of the brightness of the sub-pixels 122 of the color is substantially equal to the target brightness. In this way, the sub-pixels 122 with repeated colors in the auxiliary pixel 120 will not cause color aberration at the boundary of the active area AA. In some embodiments, "substantially equal" may mean that the difference between the sum of brightness and the target brightness is within 5%. In other embodiments, "substantially equal to" may mean that the difference between the sum of brightness and the target brightness is within 10%.

For example, please refer to Figure 2A again. If the display device 100 wants the auxiliary pixel 120 to generate red light with a target brightness of 100 nits, and the auxiliary pixel 120 has two red sub-pixels 122 ( For example, the red sub-pixels 122 marked with "X" and "Y"), the display device 100 will set the sum of the brightness of the two red sub-pixels 122 to 100 nits, for example, to 50 nits and 50 nits respectively. special. Similarly, if the display device 100 is used to cause the auxiliary pixel 120 to generate green light with a target brightness of 80 nits, and the auxiliary pixel 120 has two green sub-pixels 122 (for example, marked with “P” and “Q” green sub-pixel 122), the display device 100 will set the sum of the brightness of the two green sub-pixels 122 to 80 nits.

In some embodiments, for sub-pixels 122 of the same color in the auxiliary pixel 120 , the brightness is positively correlated with the distance from the frame 130 . For example, please refer to Figure 2A. The red sub-pixel 122 marked with "X" in Figure 2A is closer to the frame 130 than the red sub-pixel 122 marked with "Y". Therefore, when the target brightness of the red color light When it is 100 nits, the brightness of the red sub-pixel 122 marked with "X" can be a lower brightness of 30 nits, and the brightness of the red sub-pixel 122 marked with "Y" can be a higher brightness of 70 nits. . In this way, the position of the red light source perceived by the user will be closer to the red sub-pixel 122 marked with "Y". The advantage of this configuration is that the light mixing effect of the auxiliary pixel 120 and the ordinary pixel 110 tends to be consistent.

As can be seen from the above, the display device 100 can set the sub-pixels 122 of the same color in the auxiliary pixel 120 to have the same brightness or different brightnesses, so that the sum of their brightnesses is substantially equal to the target brightness. The following will further describe an embodiment in which sub-pixels 122 of the same color are set to have the same brightness with reference to Figures 3 to 4. FIG. 3 is a partially enlarged schematic diagram of a display device 100 according to an embodiment of this disclosure document. The driver chip 140 includes a timing controller 310 and a source driver 320 . The timing controller 310 is used to receive display data Da. The display data Da includes the grayscale values of each color light of each ordinary pixel 110 and each auxiliary pixel 120 in Figures 1 to 2. For example, the display data Da can specify an auxiliary pixel. The blue light, red light and green light generated by the pixel 120 correspond to 0 gray level, 255 gray level and 255 gray level respectively so that the user can perceive the yellow light.

For convenience of explanation, Figure 3 only shows one auxiliary pixel 120 to represent the auxiliary pixel 120 in Figures 1-2, and the ordinary pixel 110 in Figures 1-2 is omitted. The auxiliary pixel 120 includes two red sub-pixels 122 (marked with "R"), two green sub-pixels 122 (with internal circuits shown), and one blue sub-pixel 122 (marked with "B") . The red and blue sub-pixels 122 are similar to the green sub-pixels 122. The difference lies in the colors of the light-emitting elements. Therefore, the circuit structures of the red and blue sub-pixels 122 are omitted in FIG. 3 . The following uses the green sub-pixel 122 as an example to illustrate the operation of the embodiment in FIG. 3 .

The timing controller 310 will process the grayscale value of the green light associated with the auxiliary pixel 120 in the display data Da (hereinafter referred to as the green grayscale value) according to the number of green sub-pixels 122 in the auxiliary pixel 120 to generate a The processed green grayscale value. The green grayscale value is used to specify the target brightness of the green light generated by the auxiliary pixel 120 , and the processed green grayscale value is used to specify the brightness of multiple green sub-pixels 122 such that the sum of the brightness of the green sub-pixels 122 Essentially equal to the target brightness. The source driver 320 is used to provide the same data voltage Vdata to the plurality of green sub-pixels 122 according to the processed green grayscale value. That is, the plurality of green sub-pixels 122 in this embodiment receive the data voltage Vdata from the same data line, and therefore have the same brightness. The green sub-pixel 122 includes a driving circuit 330 and a light-emitting element 340, where the driving circuit 330 is used to provide a driving current to the light-emitting element 340 according to the data voltage Vdata to cause the light-emitting element 340 to emit light.

Please refer to Figure 3 and Figure 4 at the same time. Figure 4 is a schematic diagram showing the relationship between the brightness of the green sub-pixel 122 and the driving current. As shown in Figure 4, when the external quantum efficiency curve is approximately horizontal, the brightness of the green sub-pixel 122 and its driving current will have a roughly linear relationship, in which the target brightness is marked with the label 410, and each green sub-pixel 122 The brightness is marked with the symbol 420. The timing controller 310 can simply calculate the aforementioned processed grayscale value based on this linear relationship and/or the gamma correction (Gamma Correction) curve stored in the source driver 320 .

It is worth noting that the target brightness (label 410) in Figure 4 and the current size corresponding to the target brightness (hereinafter referred to as the target current) can be understood as when the ordinary pixel 110 is used to provide the target brightness, the ordinary pixel 110 A single green sub-pixel 112 will have brightness and current. In the case where the auxiliary pixel 120 has M green sub-pixels 122, each green sub-pixel 122 can flow one-M times the target current and have one-M times the target brightness, where M is a positive integer. For example, since the auxiliary pixel 120 in FIG. 3 has two green sub-pixels 122, each green sub-pixel 122 flows through half of the target current and has half of the target brightness. In other words, when the green gray scale value is fixed, the current and brightness of the green sub-pixel 122 are negatively correlated with the total number of green sub-pixels 122 . The operation mode of other color sub-pixels 122 in the auxiliary pixel 120 is similar to the above description about the green sub-pixel 122. For the sake of simplicity, the details are not repeated here.

An embodiment in which sub-pixels 122 of the same color are set to have different brightness will be further described below with reference to Figures 5 to 6. FIG. 5 is a partially enlarged schematic diagram of a display device 100 according to another embodiment of the present disclosure. The sub-pixels 122 in Figure 5 have a horizontal arrangement discussed in connection with Figure 2A, but this disclosure is not limited thereto. The content explained below with reference to Figures 5 to 6 is also applicable to other types of sub-pixel 122 arrangements, such as the embodiments in Figures 2B to 2C. The driving chip 140 includes a timing controller 510 and a source driver 520, where the timing controller 510 is used to receive display data Da. For convenience of explanation, Figure 5 only shows a representative auxiliary pixel 120, and omits the ordinary pixel 110. The auxiliary pixel 120 includes two red sub-pixels 122 (marked with "R"), two green sub-pixels 122 (with internal circuits shown), and one blue sub-pixel 122 (marked with "B") . The red and blue sub-pixels 122 are similar to the green sub-pixels 122. The difference lies in the colors of the light-emitting elements. Therefore, the circuit structures of the red and blue sub-pixels 122 are omitted in FIG. 5 . The following uses the green sub-pixel 122 as an example to illustrate the operation of the embodiment in FIG. 5 .

The timing controller 510 processes the green grayscale value associated with the auxiliary pixel 120 in the display data Da according to the number of green sub-pixels 122 in the auxiliary pixel 120 to generate a plurality of processed green grayscale values. The green grayscale value is used to specify the target brightness of the green light generated by the auxiliary pixel 120 . The multiple processed green grayscale values are used to specify the brightness of multiple green sub-pixels 122 respectively, so that the sum of the brightness of the green sub-pixels 122 is substantially equal to the target brightness, where the brightness of the multiple green sub-pixels 122 can be Same or different. The source driver 320 is used to provide a plurality of data voltages Vdata to a plurality of green sub-pixels 122 according to a plurality of processed green grayscale values. The green sub-pixel 122 includes a driving circuit 530 and a light-emitting element 540. The driving circuit 530 is used to provide a driving current to the light-emitting element 540 according to the data voltage Vdata to cause the light-emitting element 540 to emit light.

Please refer to Figure 5 and Figure 6 at the same time. Figure 6 is a schematic diagram showing the relationship between the brightness of the green sub-pixel 122 and the driving current. In FIG. 6 , the target brightness is marked with reference numeral 610 , and the brightnesses of the green sub-pixels 122 are marked with reference numerals 620 and 630 respectively. The target brightness (label 610) in Figure 6 and the current size corresponding to the target brightness (hereinafter referred to as the target current) can be understood as a single green sub-pixel of the ordinary pixel 110 when the ordinary pixel 110 is used to provide the target brightness. 122 will have the brightness and current. The timing controller 510 can simply calculate the aforementioned processed green grayscale value based on the linear relationship between brightness and current in Figure 6 and/or the gamma correction curve stored in the source driver 520, so as to adjust the target brightness to a predetermined value. The proportional relationship is assigned to the plurality of green sub-pixels 122, that is, the driving currents of the plurality of green sub-pixels 122 will have a predetermined ratio. For example, since the auxiliary pixel 120 in Figure 5 has two green sub-pixels 122, the brightness of the two green sub-pixels 122 can be two-fifths (labeled 620) and three-fifths (labeled 620) of the target brightness respectively. 630), or the brightness of the two green sub-pixels 122 can both be half of the target brightness, but this disclosure document is not limited to this. The operation mode of other color sub-pixels 122 in the auxiliary pixel 120 is similar to the above description about the green sub-pixel 122. For the sake of simplicity, the details are not repeated here.

In order to better understand the advantages of the display device 100 provided in this disclosure document, the operation of the ordinary pixels 110 and the auxiliary pixels 120 when the display device 100 is used to display a monochrome image will be described below with reference to FIG. 1 and FIG. 2A. In some embodiments, the display data Da is used to specify the display device 100 to generate a red picture with a first grayscale value. For example, the display data Da may specify that the target brightness of the red light generated by each ordinary pixel 110 and each auxiliary pixel 120 corresponds to the first gray level value, so that each ordinary pixel 110 and each auxiliary pixel 120 Used to generate 0 nits of blue light, 100 nits (that is, the target brightness) of red light, and 0 nits of green light to allow users to perceive red light.

In this case, please refer to Figure 2A. The red sub-pixel 112 of each ordinary pixel 110 will generate red light with a target brightness (eg, 100 nits). The sum of the brightness of the two red sub-pixels 122 labeled "X" and "Y" in the auxiliary pixel 120 will be substantially equal to the target brightness (such as 100 nits), such as 40 nits and 60 nits respectively, or 50 nits and 50 nits respectively. In other words, the sum of the brightness of the two red sub-pixels 122 marked with “X” and “Y” in the auxiliary pixel 120 will be substantially equal to the brightness of the red sub-pixel 112 of the ordinary pixel 110 . Therefore, based on the first grayscale value, both the ordinary pixel 110 and the auxiliary pixel 120 can provide red light of target brightness to the user.

Similarly, in other embodiments, the display data Da is used to specify that the display device 100 generates a green picture with a second grayscale value. The display data Da may specify that each ordinary pixel 110 and each auxiliary pixel 120 generate a green picture. The target brightness of the green light corresponds to this second grayscale value, so that each normal pixel 110 and each auxiliary pixel 120 are used to produce 0 nits of blue light, 0 nits of red light and 100 nits ( That is, the green light of the target brightness) allows the user to perceive the green light. In this case, the green sub-pixel 112 of each common pixel 110 generates green light with a target brightness (eg, 100 nits). The sum of the brightness of the two green sub-pixels 122 labeled "P" and "Q" in the auxiliary pixel 120 will be substantially equal to the target brightness (eg, 100 nits). Therefore, according to the second grayscale value, both the ordinary pixel 110 and the auxiliary pixel 120 can provide green light of target brightness to the user. The methods for generating light of other colors are similar to the above content, and for the sake of simplicity, they will not be repeated here.

From the above, it can be seen that even if the display device 100 displays a monochrome picture in which defects are easily found, the user will not observe the color aberration phenomenon at the boundary of the active area AA. Therefore, the display device 100 and the pixel structure including the ordinary pixel 110 and the auxiliary pixel 120 provided in this disclosure document are suitable for various application scenarios that require high-quality non-rectangular images.
