Display panel and its driving method

Abstract

This invention proposes a display panel and its driving method. The display panel includes a first group of sub-pixels and a second group of sub-pixels. In a first period, the first group of sub-pixels displays a first image; in a second period, the second group of sub-pixels displays a second image. The second period follows the first period, and the content of the second image differs from the content of the first image. This avoids the phenomenon of image retention.

Description

Technical Field

[0001] This disclosure relates to a display panel and its driving method, the display panel comprising two sets of pixel units for displaying different images. Background Technology

[0002] Display panels are widely used in daily life. In some applications, LCD panels are used in electronic tags to display product information. If the product information does not change frequently, the image displayed on the LCD panel will remain unchanged for a period of time. Since LCD panels rely on voltage differences to rotate liquid crystal molecules, a fixed voltage difference when the displayed image remains unchanged can cause ions to accumulate on a specific electrode or structure. When the displayed image changes, these ions can prevent the display panel from generating the predetermined voltage difference, resulting in image retention in the new image. Summary of the Invention

[0003] The embodiments disclosed herein provide a display device including a display panel. The display panel includes a plurality of pixel units, which are divided into a first group of pixel units and a second group of pixel units. During a first period, the first group of pixel units receives a first data signal, and the display panel displays a first image. During a second period, the second group of pixel units receives a second data signal, and the display panel displays a second image. The second period occurs after the first period, and the first image is different from the second image.

[0004] In some embodiments, the display panel is a normally black display panel, where each pixel unit of the second group of pixel units is in a dark state during a first period, and each pixel unit of the first group of pixel units is in a dark state during a second period.

[0007] In some embodiments, the first group of pixel units and the second group of pixel units each include a plurality of fourth color pixel units.

[0056] The terms "first," "second," etc., used in this article do not specifically refer to order or sequence; they are merely used to distinguish elements or operations described using the same technical terms.

[0057] Figure 1 These are schematic diagrams illustrating the display device according to the first to fifth embodiments. Please refer to... Figure 1 The display device 100 includes a gate driver 110, a source driver 120, and a display panel 130. The display panel 130 may include a liquid crystal display panel, which may be, for example, a transmission-type liquid crystal display panel, a reflective-type liquid crystal display panel, or a transflective-reflective liquid crystal display panel, etc., and this disclosure is not limited thereto. Furthermore, in some embodiments, the display panel 130 may include an electrophoretic display panel or a self-emissive display panel (e.g., a light-emitting diode display panel). In some embodiments, the display panel 130 may also include at least one polarizing film. For example, in embodiments where the display panel 130 includes a liquid crystal display panel, the display panel 130 may include a liquid crystal cell and at least one polarizing film disposed on at least one side of the liquid crystal cell, but this is not a limitation. The display panel 130 may be a normally white type display panel or a normally black type display panel 130. For example, in an embodiment where the display panel 130 is a normally black liquid crystal display panel, when no voltage is applied to the liquid crystal, the transmittance or reflectance of the display panel 130 is at its minimum, resulting in a black screen; while in an embodiment where the display panel 130 is a normally white liquid crystal display panel, when no voltage is applied to the liquid crystal, the transmittance or reflectance of the display panel 130 is at its maximum, resulting in a white screen. The display area AA of the display panel 130 includes multiple pixel units PU. The pixel units PU in the display panel 130 are arranged in multiple rows and multiple columns, for example, arranged in M ​​pixel unit columns C(1)-C(M) and N pixel unit rows R(1)-R(N). The gate driver 110 is electrically connected to these pixel units PU through multiple gate lines SL, and the source driver 120 is electrically connected to these pixel units PU through multiple data lines DL. Furthermore, the source driver 120 and / or the gate driver 110 may be wafer-type and coupled to the display panel 130 via a chip-on-glass (COG) manner or via a flexible circuit board, but are not limited thereto. Additionally, in some embodiments, the gate driver 110 may be a gate driver in panel (GIP) and disposed within the display panel 130.

[0058] In this invention, the display device 100 is an electronic tag, therefore the display panel 130 can be used to display text and / or numbers (e.g., names, prices), barcodes, QR codes, or combinations thereof, and this disclosure is not limited thereto. Since electronic tags are primarily used to display static images and the content of each image remains unchanged for a relatively long time, in some embodiments, the frame rate of the display panel 130 is less than or equal to 30 Hz. In some embodiments, the frame rate of the display panel 130 is less than or equal to 1 Hz. Because the content of the electronic tag does not change frequently—that is, an image is displayed for a long time before switching to the next image with different content—to avoid image retention on the display panel 130 after switching to the next image, this invention uses one set of pixel units to display one image, and another set of pixel units to display another image when switching to a different image. The configuration and driving method of the pixel units of the display panel 130 of the display device 100 of this invention will be described next using the first to fifth embodiments to solve the image retention problem of electronic tags.

[0059] [First Embodiment]

[0060] Figure 2 yes Figure 1 A schematic diagram of some pixel units of the display panel. Figure 2 yes Figure 1 This is a schematic diagram of a portion of the pixel units (i.e., 12 columns multiplied by 9 rows, totaling 108 pixel units PU) of the display panel 130. Specifically, it shows the pixel units PU located at the intersection of pixel unit columns C(i) to C(i+11) and pixel unit rows R(j) to R(j+8), where i and j are positive integers greater than or equal to 1, (i+11) is less than or equal to M, and (j+8) is less than or equal to N. Please refer to... Figure 1 and Figure 2The pixel unit PU in the display panel 130 includes a plurality of first color pixel units R, a plurality of second color pixel units G, and a plurality of third color pixel units. The first, second, and third color pixel units R, G, and B can be used to display the first, second, and third colors, respectively. For example, the colors of the color filter layers of the first, second, and third color pixel units R, G, and B are different from each other so that the first, second, and third color pixel units R, G, and B can display the first, second, and third colors, respectively, but this is not a limitation. In this embodiment, the pixel unit PU is a sub-pixel, and one first color pixel unit R, one second color pixel unit G, and one third color pixel unit constitute one pixel, but this is not a limitation. In this embodiment, pixel units PU in the same column have the same color, and pixel units PU in adjacent columns have different colors. For example, pixel units PU in pixel unit column C(i) are all first-color pixel units R, pixel units in pixel unit column C(i+1) are all second-color pixel units G, pixel units in pixel unit column C(i+2) are all third-color pixel units B, pixel units in pixel unit column C(i+3) are all first-color pixel units R, and so on.

[0061] Specifically, in this embodiment, all pixel units PU are divided into two groups, referred to as the first group of pixel units 140 and the second group of pixel units 150, and each group of pixel units includes multiple pixel units PU. In this embodiment, the first group of pixel units 140 includes multiple first color pixel units R-1, multiple second color pixel units G-1, and multiple third color pixel units B-1, and the second group of pixel units 150 includes multiple first color pixel units R-2, multiple second color pixel units G-2, and multiple third color pixel units B-2. In this embodiment, two adjacent sub-pixel units PU in the same pixel unit column belong to different groups of pixel units, while every three adjacent pixel units PU in the same pixel unit row belong to the same group of pixel units. For example, the first to third color pixel units R-1, G-1, and B-1 located at the intersection of pixel unit row R(j) and pixel unit columns C(i), C(i+1), and C(i+2) belong to the first group of pixel units 140; the first to third color pixel units R-2, G-2, and B-2 located at the intersection of pixel unit row R(j) and pixel unit columns C(i+3), C(i+4), and C(i+5) belong to the second group of pixel units 150; the first to third color pixel units R-2, G-2, and B-2 located at the intersection of pixel unit row R(j+1) and pixel unit columns C(i), C(i+1), and C(i+2) belong to the second group of pixel units 150; and the first to third color pixel units R-1, G-1, and B-1 located at the intersection of pixel unit row R(j+1) and pixel unit columns C(i+3), C(i+4), and C(i+5) belong to the first group of pixel units 140. The pixel units PU in the first group of pixel units 140 are different from the pixel units PU in the second group of pixel units 150; that is, the first group of pixel units 140 and the second group of pixel units 150 do not share pixel units PU. In other words, three sub-pixel units PU in the first group of pixel units 140 are located in the same row, arranged adjacently, and are respectively the first color pixel unit R-1, the second color pixel unit G-1, and the third color pixel unit B-1. Similarly, three pixel units PU in the second group of pixel units 150 are also located in the same row, arranged adjacently, and are respectively the first color pixel unit R-2, the second color pixel unit G-2, and the third color pixel unit B-2.

[0062] Figure 3 This is a schematic diagram illustrating the first and second screens displayed on the display panel according to the first embodiment. Figure 4 This is an operational schematic diagram illustrating the first group of pixel units and the second group of pixel units according to the first embodiment. Please refer to... Figure 3 and Figure 4 Here Figure 3This example uses an electronic tag applied to a shelf, where the tag's image includes the product name, barcode, and price. However, the application and content of the electronic tag are not limited to this. During the display of the first image, the first group of pixel units 140 of the display panel 130 receives the first data signal, and each pixel unit in the second group of pixel units 150 (i.e., each of the first to third color pixel units R-2, G-2, B-2 in the second group of pixel units 150) remains either dark or bright (for example, if the display panel 130 is a normally black display panel, the second group of pixel units 150 remains dark; if the display panel 130 is a normally white display panel, the second group of pixel units 150 remains bright). When the display device 100 is switched from the first... After switching from one screen to the second screen, during the display of the second screen, the second group of pixel units 150 of the display panel 130 receives the second data signal, and each pixel unit in the first group of pixel units 140 (i.e., each of the first to third color pixel units R-1, G-1, B-1 in the first group of pixel units 140) remains in a dark state or a bright state (for example, if the display panel 130 is a normally black display panel, then the first group of pixel units 140 remains in a dark state; if the display panel 130 is a normally white display panel, then the first group of pixel units 140 remains in a bright state). In this embodiment, the content of the first screen is different from the content of the second screen. For example, the first screen and the second screen each include a product name, a barcode, and a price, and at least one of the product name, barcode, and price in the first screen is different from that in the second screen. For example, the first screen may include product name A, barcode A, and price A, and the second screen may include product name B, barcode B, and price B, where the content of at least one of product name A, barcode A, and price A differs from the content of at least one corresponding to product name B, barcode B, and price B. Since electronic tags are primarily used to display static images and the content of each screen remains unchanged for a considerable period, in some embodiments, the content of the first screen remains unchanged across multiple frames, and the content of the second screen also remains unchanged across multiple frames. For example, the first screen may remain unchanged for one minute; if the frame frequency of the display panel 130 is equal to 1 Hz, this means the first screen remains unchanged across 60 frames. Similarly, the second screen may also remain unchanged for one minute, thus remaining unchanged across 60 frames. This disclosure does not limit the duration for which the first and second screens remain unchanged.

[0063] Figure 5 yes Figure 2 The first to third color pixel units are red, green and blue pixel units, respectively. Figure 6 yes Figure 5 This is a diagram illustrating the state of pixel units during the first and second frames. Please refer to... Figure 1 , Figure 2 , Figure 5and Figure 6 .like Figure 2 and Figure 5 As shown, the first color pixel unit R, the second color pixel unit G, and the third color pixel unit B can be a red pixel unit, a green pixel unit, and a blue pixel unit, respectively, but the colors of the first to third color pixel units R, G, and B are not limited to these. It should be noted that in... Figure 6 In this embodiment, the display panel 130 is a normally black display panel as an example. Figure 6 As shown, Figure 6 The illustration shows the display state S1 of some pixel units of the display panel 130 during a first period (or a first screen period) and the display state S2 during a second period (or a second screen period), wherein the display panel 130 displays a first screen and a second screen during the first period and the second period, respectively. During the first period, the display panel 130 receives a first data signal from the source driver 120. Specifically, during the first period, the first data signal is transmitted to the first to third color pixel units R-1, G-1, and B-1 of the first group of pixel units 140 to display the corresponding screen, while the first to third color pixel units R-2, G-2, and B-2 of the second group of pixel units 150 all display black (specifically, the first to third color pixel units R-2, G-2, and B-2 of the second group of pixel units 150 are all in the darkest state). For example, during the first period, a first data signal may be transmitted to the first group of pixel units 140 but not to the second group of pixel units 150. The first to third color pixel units R-2, G-2, and B-2 of the second group of pixel units 150 may receive the signal of the darkest grayscale image from the source driver 120. Therefore, the first to third color pixel units R-2, G-2, and B-2 of the second group of pixel units 150 all display black. The first data signal may be transmitted to the first to third color pixel units R-1, G-1, and B-1 of the first group of pixel units 140 so that at least a portion of the first group of pixel units 140 is in a grayscale state different from that of the second group of pixel units 150 (e.g., at least a portion of the first group of pixel units 140 is in a bright state), but this is not a limitation. Figure 6In display state S1, the first to third color pixel units R-2, G-2, and B-2 of the second group of pixel units 150 are displayed as black, represented by a dotted pattern. During the second period, the display panel 130 receives a second data signal from the source driver 120. Specifically, during the second period, the second data signal is transmitted to the first to third color pixel units R-2, G-2, and B-2 of the second group of pixel units 150 to display the corresponding image, while the first to third pixel units R-1, G-1, and B-1 of the first group of pixel units 140 are all displayed as black (specifically, the first to third color pixel units R-1, G-1, and B-1 of the first group of pixel units 140 are all in the darkest state). For example, during the second period, the second data signal can be transmitted to the second group of pixel units 150 but not to the first group of pixel units 140. The first to third color pixel units R-1, G-1, and B-1 of the first group of pixel units 140 can receive the signal of the darkest grayscale image from the source driver 120. Therefore, the first to third color pixel units R-1, G-1, and B-1 of the first group of pixel units 140 all display black. The second data signal can be transmitted to the first to third color pixel units R-2, G-2, and B-2 of the second group of pixel units 150 so that at least a portion of the second group of pixel units 150 is in a grayscale state different from that of the first group of pixel units 140 (e.g., at least a portion of the second group of pixel units 150 is in a bright state), but is not limited thereto. Figure 6 In display state S2, the first to third color pixel units R-1, G-1, and B-1 of the first group of pixel units 140 are represented by a dotted pattern, and all are displayed in black. The second period follows the first period, and the length of this first period and the second period can be several seconds, several minutes, several hours, or several days, and this disclosure is not limited thereto. The content of the second screen is different from the content of the first screen; for example, the first screen and the second screen display different product names, barcodes, and / or prices.

[0064] In a variation embodiment, the display panel 130 may also be a normally white display panel. Unlike a normally black display panel, during the first period (display state S1), the first to third color pixel units R-2, G-2, and B-2 of the second group of pixel units 150 display the first, second, and third colors respectively (specifically, the first to third color pixel units R-2, G-2, and B-2 of the second group of pixel units 150 are all in their brightest state), and the source driver 120 transmits the first data signal to the first to third color pixel units R-1, G-1, and B-1 of the first group of pixel units 140 for display. The corresponding screen; and during the second period (display state S2), the first to third color pixel units R-1, G-1, and B-1 of the first group of pixel units 140 display the first color, the second color, and the third color respectively (specifically, the first to third color pixel units R-1, G-1, and B-1 of the first group of pixel units 140 are all in the brightest state), and the source driver 120 transmits the second data signal to the first to third color pixel units R-2, G-2, and B-2 of the second group of pixel units 150 to display the corresponding screen. For example, during the first period (display state S1), the first data signal can be transmitted to the first group of pixel units 140 but not to the second group of pixel units 150. The first to third color pixel units R-2, G-2, and B-2 of the second group of pixel units 150 can receive the signal of the brightest grayscale image from the source driver 120 to display the first color, second color, and third color respectively. The first data signal can be transmitted to the first to third color pixel units R-1, G-1, and B-1 of the first group of pixel units 140 so that at least a portion of the first group of pixel units 140 is in a grayscale state different from that of the second group of pixel units 150 (e.g., at least a portion of the first group of pixel units 140 is in a grayscale state lower than the brightest grayscale). While... During the second period (display state S2), the second data signal can be transmitted to the second group of pixel units 150 but not to the first group of pixel units 140. The first to third color pixel units R-1, G-1, and B-1 of the first group of pixel units 140 can receive the signal of the brightest grayscale image from the source driver 120 to display the first color, the second color, and the third color respectively. The second data signal can be transmitted to the first to third color pixel units R-2, G-2, and B-2 of the second group of pixel units 150 so that at least a portion of the second group of pixel units 150 is in a grayscale state different from that of the first group of pixel units 140 (for example, at least a portion of the second group of pixel units 150 is in a grayscale state lower than the brightest grayscale), but is not limited thereto.

[0065] Figure 7 This is another operational schematic diagram illustrating the first group of pixel units and the second group of pixel units according to the first embodiment. For example... Figure 7As shown, the display panel 130 sequentially displays the first to the Kth frames, and the content of the Pth frame is different from the content of the (P-1)th frame, where K and P are positive integers, and P is greater than 2 and less than or equal to K. During the display of the (R-1)th frame, R is an even number less than or equal to K. The first to third color pixel units R-1, G-1, and B-1 of the first group of pixel units 140 of the display panel 130 receive the (R-1)th data signal, and each pixel unit of the second group of pixel units 150 (i.e., each of the first to third color pixel units R-2, G-2, and B-2 in the second group of pixel units 150) remains either dark or bright (for example, if the display panel 130 is a normally black display panel, then the second group of pixel units 150 remains dark; if the display panel 130 is a normally white display panel, then the second group of pixel units 150 remains bright). Unit 150 remains in a bright state; during the display of the Rth frame, the first to third color pixel units R-2, G-2, B-2 of the second group of pixel units 150 of the display panel 130 receive the Rth data signal, and each pixel unit in the first group of pixel units 140 (i.e. each of the first to third color pixel units R-1, G-1, B-1 in the first group of pixel units 140) remains in a dark state or a bright state (for example, if the display panel 130 is a normally black display panel, then the first group of pixel units 140 remains in a dark state; if the display panel 130 is a normally white display panel, then the first group of pixel units 140 remains in a bright state).

[0066] [Second Embodiment]

[0067] Figure 8 It is illustrated according to the second embodiment. Figure 1 This is a partial pixel arrangement diagram of the display panel. Please refer to... Figure 1 and Figure 8In this embodiment, all pixel units PU are divided into two groups, referred to as the first group of pixel units 140a and the second group of pixel units 150a, and each group of pixel units includes multiple pixel units PU. In this embodiment, the first group of pixel units 140a includes multiple first color pixel units R-1, multiple second color pixel units G-1, and multiple third color pixel units B-1, and the second group of pixel units 150a includes multiple first color pixel units R-2, multiple second color pixel units G-2, and multiple third color pixel units B-2. In this embodiment, the pixel units PU in the first group of pixel units 140a are different from the pixel units PU in the second group of pixel units 150a, that is, the first group of pixel units 140a and the second group of pixel units 150a do not share pixel units PU. In this embodiment, pixel unit column C(i) is adjacent to pixel unit column C(i+1) (or pixel unit column C(i+6) and pixel unit column C(i+7)) and contains only first-color pixel units R; pixel unit column C(i+2) is adjacent to pixel unit column C(i+3) (or pixel unit column C(i+8) and pixel unit column C(i+9)) and contains only second-color pixel units G; pixel unit column C(i+4) is adjacent to pixel unit column C(i+5) (or pixel unit column C(i+10) and pixel unit column C(i+11)) and contains only third-color pixel units B. Two adjacent pixel units PU of the same color in the same row belong to different groups of pixel units. Furthermore, two adjacent pixel units PU in the same column also belong to different groups of pixel units. For example, the three pixel units PU located at the intersection of pixel unit columns C(i), C(i+2), C(i+4) and pixel unit row R(j) are the first to third color pixel units R-1, G-1, and B-1 of the first group of pixel units 140a, respectively. The three pixel units PU located at the intersection of pixel unit columns C(i+1), C(i+3), C(i+5) and pixel unit row R(j) are the first to third color pixel units R-2, G-2, and B-2 of the second group of pixel units 150a, respectively. The three pixel units PU located at the intersection of pixel unit columns C(i), C(i+2), C(i+4) and pixel unit row R(j+1) are the first to third color pixel units R-2, G-2, and B-2 of the second group of pixel units 150a, respectively. Meanwhile, the three pixel units PU located at the intersection of pixel unit columns C(i+1), C(i+3), C(i+5) and pixel unit row R(j+1) are the first to third color pixel units R-1, G-1, and B-1 of the first group of pixel units 140a, respectively. In other words, multiple pixel units in the first group of pixel units 140a in the same column (or row) are arranged alternately, and multiple pixel units in the second group of pixel units 150a in the same column (or row) are also arranged alternately.

[0068] Figure 9 yes Figure 8 The first to third color pixel units are state diagrams for red, green, and blue pixel units, respectively. Figure 10 yes Figure 9 A schematic diagram of pixel units during the first frame and the second frame. Please refer to... Figure 1 and Figures 8-10 The first color pixel unit R, the second color pixel unit G, and the third color pixel unit B can be a red pixel unit, a green pixel unit, and a blue pixel unit, respectively, but the colors of the first to third color pixel units R, G, and B are not limited to these. It should be noted that in... Figure 10 In this embodiment, the display panel 130 is a normally black display panel as an example. Figure 10 As shown, Figure 10 The illustration shows the display state S1 of some pixel units of the display panel 130 during a first period and the display state S2 during a second period. The display panel 130 displays a first image and a second image during the first period and the second period, respectively. During the first period, the display panel 130 receives a first data signal from the source driver 120. Specifically, during the first period, the first data signal is transmitted to the first to third color pixel units R-1, G-1, and B-1 of the first group of pixel units 140a to display the corresponding image, while the first to third color pixel units R-2, G-2, and B-2 of the second group of pixel units 150a all display black (specifically, the first to third color pixel units R-2, G-2, and B-2 of the second group of pixel units 150a are all in the darkest state). For example, during the first period, a first data signal may be transmitted to the first group of pixel units 140a but not to the second group of pixel units 150a. The first to third color pixel units R-2, G-2, and B-2 of the second group of pixel units 150a may receive the signal of the darkest grayscale image from the source driver 120. Therefore, the first to third color pixel units R-2, G-2, and B-2 of the second group of pixel units 150a all display black. The first data signal may be transmitted to the first to third color pixel units R-1, G-1, and B-1 of the first group of pixel units 140a so that at least a portion of the first group of pixel units 140a is in a grayscale state different from that of the second group of pixel units 150a (e.g., at least a portion of the first group of pixel units 140a is in a bright state), but this is not a limitation. Figure 10In display state S1, the first to third color pixel units R-2, G-2, and B-2 of the second group of pixel units 150a are displayed as black, represented by a dotted pattern. During the second period, the display panel 130 receives a second data signal from the source driver 120. Specifically, during the second period, the second data signal is transmitted to the first to third color pixel units R-2, G-2, and B-2 of the second group of pixel units 150a to display the corresponding image, while the pixel units R-1, G-1, and B-1 of the first group of pixel units 140a are all displayed as black (specifically, the pixel units R-1, G-1, and B-1 of the first group of pixel units 140a are all in the darkest state). For example, during the second period, the second data signal can be transmitted to the second group of pixel units 150a but not to the first group of pixel units 140a. The first to third color pixel units R-1, G-1, and B-1 of the first group of pixel units 140a can receive the signal of the darkest grayscale image from the source driver 120. Therefore, the first to third color pixel units R-1, G-1, and B-1 of the first group of pixel units 140a all display black. The second data signal can be transmitted to the first to third color pixel units R-2, G-2, and B-2 of the second group of pixel units 150a so that at least a portion of the second group of pixel units 150a is in a grayscale state different from that of the first group of pixel units 140a (e.g., at least a portion of the second group of pixel units 150a is in a bright state), but is not limited thereto. Figure 10 In display state S2, the first to third color pixel units R-1, G-1, and B-1 of the first group of pixel units 140a are represented by a dotted pattern and are all displayed in black.

[0069] In a variation embodiment, the display panel 130 may also be a normally white display panel. Unlike a normally black display panel, during the first period (display state S1), the first to third color pixel units R-2, G-2, and B-2 of the second group of pixel units 150a respectively display the first, second, and third colors (specifically, the first to third color pixel units R-2, G-2, and B-2 of the second group of pixel units 150a are all in their brightest state), and the source driver 120 transmits the first data signal to the first to third color pixel units R-1, G-1, and B-1 of the first group of pixel units 140a for display. The corresponding screen; and during the second period (display state S2), the first to third color pixel units R-1, G-1, and B-1 of the first group of pixel units 140a display the first color, the second color, and the third color respectively (specifically, the first to third color pixel units R-1, G-1, and B-1 of the first group of pixel units 140a are all in the brightest state), and the source driver 120 transmits the second data signal to the first to third color pixel units R-2, G-2, and B-2 of the second group of pixel units 150a to display the corresponding screen. For example, during the first period (display state S1), the first data signal can be transmitted to the first group of pixel units 140a but not to the second group of pixel units 150a. The first to third color pixel units R-2, G-2, and B-2 of the second group of pixel units 150a can receive signals from the source driver 120 for the brightest grayscale image to display the first, second, and third colors respectively. The first data signal can be transmitted to the first to third color pixel units R-1, G-1, and B-1 of the first group of pixel units 140a so that at least a portion of the first group of pixel units 140a is in a grayscale state different from that of the second group of pixel units 150a (e.g., at least a portion of the first group of pixel units 140a is in a grayscale state lower than the brightest grayscale). While... During the second period (display state S2), the second data signal can be transmitted to the second group of pixel units 150a but not to the first group of pixel units 140a. The first to third color pixel units R-1, G-1, and B-1 of the first group of pixel units 140a can receive the signal of the brightest grayscale image from the source driver 120 to display the first color, the second color, and the third color respectively. The second data signal can be transmitted to the first to third color pixel units R-2, G-2, and B-2 of the second group of pixel units 150a so that at least a portion of the second group of pixel units 150a is in a grayscale state different from that of the first group of pixel units 140a (for example, at least a portion of the second group of pixel units 150a is in a grayscale state lower than the brightest grayscale), but is not limited thereto.

[0070] In the first embodiment, the three first to third color pixel units R-1, G-1, B-1 of the first group of pixel units 140 and the three first to third color pixel units R-2, G-2, B-2 of the second group of pixel units 150 in the same pixel unit row are arranged in sequence to form an arrangement of R-1 / G-1 / B-1 / R-2 / G-2 / B-2. Therefore, there is a distance of three pixel units PU between the three first to third color pixel units R-1, G-1, B-1 of the first group of pixel units 140 in the same pixel unit row and the other three first to third color pixel units R-1, G-1, B-1 (or the three first to third color pixel units R-2, G-2, B-2 of the second group of pixel units 150 and the other three first to third color pixel units R-2, G-2, B-2). In the second embodiment, the three first to third color pixel units R-1, G-1, B-1 of the first group of pixel units 140a in the same pixel unit row and the three first to third color pixel units R-2, G-2, B-2 of the second group of pixel units 150a are alternately arranged to form an arrangement of R-1 / R-2 / G-1 / G-2 / B-1 / B-2. Therefore, the image quality of the second embodiment is better than that of the first embodiment.

[0071] [Third Embodiment]

[0072] Figure 11 It is illustrated according to the third embodiment. Figure 1 This is a partial pixel arrangement diagram of the display panel. Please refer to... Figure 1 and Figure 11In the first and second embodiments, the first group of pixel units 140 and the second group of pixel units 150 (or the first group of pixel units 140a and the second group of pixel units 150a) are different from each other, that is, the first group of pixel units 140 and the second group of pixel units 150 (or the first group of pixel units 140a and the second group of pixel units 150a) do not share pixel units PU. However, in this embodiment, the first group of pixel units 140b and the second group of pixel units 150b are partially the same, that is, the first group of pixel units 140b and the second group of pixel units 150b share pixel units PU. Specifically, the first group of pixel units 140b and the second group of pixel units 150b share the third color pixel unit B. In this embodiment, all pixel units PU are divided into two groups, referred to as the first group of pixel units 140b and the second group of pixel units 150b, and each group of pixel units includes multiple pixel units PU. In this embodiment, the first group of pixel units 140b includes multiple first color pixel units R-1, multiple second color pixel units G-1, and multiple third color pixel units B, and the second group of pixel units 150b includes multiple first color pixel units R-2, multiple second color pixel units G-2, and multiple third color pixel units B. In this embodiment, the first group of pixel units 140b and the second group of pixel units 150b share the third color pixel units B. Figure 11As shown, pixel unit row R(j) contains only second-color pixel units G. Pixel unit row R(j+1) contains only first-color pixel units R and third-color pixel units B, where the ratio of the number of first-color pixel units R to the number of third-color pixel units B is 2:1, and the left and right sides of the third-color pixel unit B are the first-color pixel units R of the same group of pixel units. For example, the three pixel units PU located at the intersection of pixel unit columns C(i), C(i+1), C(i+2) and pixel unit row R(j+1) are the first-color pixel unit R-2, the third-color pixel unit B, and the first-color pixel unit R-2 of the second group of pixel units 150b, respectively; the three pixel units PU located at the intersection of pixel unit columns C(i+3), C(i+4), C(i+5) and pixel unit row R(j+1) are the first-color pixel unit R-1, the third-color pixel unit B, and the first-color pixel unit R-1 of the first group of pixel units 140b, respectively. Specifically, the first color pixel unit to the left and right of one of two adjacent third color pixel units B in the same pixel unit row (e.g., the third color pixel unit B located at the intersection of pixel unit column C(i+1) and pixel unit row R(j+1) and the third color pixel unit B located at the intersection of pixel unit column C(i+4) and pixel unit row R(j+1)) (e.g., the third color pixel unit B located at the intersection of pixel unit column C(i) and pixel unit row R(j+1)). Pixel unit R-2 and the first-color pixel unit R-2 located at the intersection of pixel unit column C(i+2) and pixel unit row R(j+1) belong to different groups of pixel units. Pixel unit row R(j+2) contains only the second-color pixel unit G. Pixel unit row R(j+3) contains only the first-color pixel unit R. The pixel unit row R(j+4) contains only second-color pixel units G and third-color pixel units B, wherein the ratio of the number of second-color pixel units G to the number of third-color pixel units B is 2:1, and the left and right sides of the third-color pixel unit B are the second-color pixel units G of the same group of pixel units.For example, the three pixel units PU located at the intersection of pixel unit columns C(i), C(i+1), C(i+2) and pixel unit row R(j+4) are the second color pixel unit G-1, the third color pixel unit B, and the second color pixel unit G-1 of the first group of pixel units 140b, respectively; the three pixel units PU located at the intersection of pixel unit columns C(i+3), C(i+4), C(i+5) and pixel unit row R(j+4) are the second color pixel unit G-2, the third color pixel unit B, and the second color pixel unit G-2 of the second group of pixel units 150b, respectively. Specifically, the second color pixel units to the left and right of one of two adjacent third color pixel units B in the same pixel unit row (e.g., the third color pixel unit B located at the intersection of pixel unit column C(i+1) and pixel unit row R(j+4) and the third color pixel unit B located at the intersection of pixel unit column C(i+4) and pixel unit row R(j+4)) (e.g., the third color pixel unit B located at the intersection of pixel unit column C(i) and pixel unit row R(j+4)) are located at the intersection of pixel unit column C(i) and pixel unit row R(j+4). Pixel unit G-1 and the second-color pixel unit G-1 located at the intersection of pixel unit column C(i+2) and pixel unit row R(j+4) belong to different groups of pixel units. The second-color pixel units to the left and right of another (e.g., the second-color pixel unit G-2 located at the intersection of pixel unit column C(i+4) and pixel unit row R(j+4), and the second-color pixel unit G-2 located at the intersection of pixel unit column C(i+5) and pixel unit row R(j+4)) belong to different groups of pixel units. Pixel unit row R(j+5) contains only the first-color pixel unit R. The 36 pixel units PU located at the intersection of pixel unit rows R(j)-R(j+5) and pixel unit columns C(i)-C(i+5) form a pixel block PB. This pixel block PB is repeated to fill the entire display area of ​​the display panel 130. For example... Figure 11As shown, the pixel units PU located to the left, right, top, and bottom of a third color pixel unit B belong to the first color pixel unit R, the first color pixel unit R, the second color pixel unit G, and the second color pixel unit G in the same group of pixel units, or belong to the second color pixel unit G, the second color pixel unit G, the first color pixel unit R, and the first color pixel unit R in the same group of pixel units. For example, the pixel units PU located to the left, right, top, and bottom of the third color pixel unit B at the intersection of pixel unit row R(j+1) and pixel unit column C(i+1) are the first color pixel unit R-2, the first color pixel unit R-2, the second color pixel unit G-2, and the second color pixel unit G-2 in the second group of pixel units 150b, respectively (e.g., the first color pixel unit R-2 located at the intersection of pixel unit column C(i) and pixel unit row R(j+1), the first color pixel unit R-2 located at the intersection of pixel unit column C(i+2) and pixel unit row R(j+1), and the first color pixel unit G-2 located at the intersection of pixel unit column C(i ... The second color pixel unit G-2 at the intersection of pixel unit row C(i+1) and pixel unit row R(j), and the second color pixel unit G-2 at the intersection of pixel unit column C(i+1) and pixel unit row R(j+2); the pixel units PU to the left, right, top, and bottom of the third color pixel unit B at the intersection of pixel unit row R(j+1) and pixel unit column C(i+4) are the first color pixel unit R-1, the first color pixel unit R-1, the second color pixel unit G-1, and the second color pixel unit G-1 of the first group of pixel units 140b (for example, located at the intersection of pixel unit column C(i+3) and pixel unit row R(j)). The first color pixel unit R-1 at the intersection of R(j+1), the first color pixel unit R-1 at the intersection of pixel unit column C(i+5) and pixel unit row R(j+1), the second color pixel unit G-1 at the intersection of pixel unit column C(i+4) and pixel unit row R(j), the second color pixel unit G-1 at the intersection of pixel unit column C(i+4) and pixel unit row R(j+2); the pixel units PU to the left, right, top, and bottom of the third color pixel unit B at the intersection of pixel unit row R(j+4) and pixel unit column C(i+1) are respectively the first group of pixel units 140 b, the second color pixel unit G-1, the second color pixel unit G-1, the first color pixel unit R-1 and the first color pixel unit R-1 (for example, the second color pixel unit G-1 located at the intersection of pixel unit column C(i) and pixel unit row R(j+4), the second color pixel unit G-1 located at the intersection of pixel unit column C(i+2) and pixel unit row R(j+4), the first color pixel unit R-1 located at the intersection of pixel unit column C(i+1) and pixel unit row R(j+3), the first color pixel unit R-1 located at the intersection of pixel unit column C(i+1) and pixel unit row R(j+5));The left, right, top, and bottom pixel units PU of the third color pixel unit B located at the intersection of pixel unit row R(j+4) and pixel unit column C(i+4) are the second color pixel unit G-2, the second color pixel unit G-2, the first color pixel unit R-2, and the first color pixel unit R-2 of the second group of pixel units 150b, respectively (for example, the second color pixel unit G-2 located at the intersection of pixel unit column C(i+3) and pixel unit row R(j+4), the second color pixel unit G-2 located at the intersection of pixel unit column C(i+5) and pixel unit row R(j+4), the first color pixel unit R-2 located at the intersection of pixel unit column C(i+4) and pixel unit row R(j+3), and the first color pixel unit R-2 located at the intersection of pixel unit column C(i+4) and pixel unit row R(j+5). Specifically, in this embodiment, the first group of pixel units 140b and the second group of pixel units 150b share the third color pixel unit B. That is, some pixel units in the first group are identical to those in the second group (i.e., the third color pixel unit B).

[0073] Figure 12 yes Figure 11 The first to third color sub-pixels are state diagrams of red, green and blue pixel units, respectively. Figure 13 yes Figure 12 A schematic diagram of pixel units during the first frame and the second frame. Please refer to... Figure 1 and Figures 11-13 The first color pixel unit R, the second color pixel unit G, and the third color pixel unit B can be a red pixel unit, a green pixel unit, and a blue pixel unit, respectively, but the colors of the first to third color pixel units R, G, and B are not limited to these. It should be noted that in... Figure 13 In this embodiment, the display panel 130 is a normally black display panel. Figure 13The illustration shows the display state S1 during a first period and the display state S2 during a second period for some pixel units of the display panel 130. The display panel 130 displays a first image and a second image during the first period and the second period, respectively. During the first period (display state S1), the first group of pixel units 140b receives a first data signal (or may be referred to as a first image signal) to display the corresponding image. Specifically, during the first period, the source driver 120 transmits the first data signal to the first group of pixel units 140b (i.e., the first color pixel unit R-1, the second color pixel unit G-1, and the third color pixel unit B) to display the corresponding image, while the first color pixel unit R-2 and the second color pixel unit G-2 of the second group of pixel units 150b both display black (i.e., the first color pixel unit R-2 and the second color pixel unit G-2 of the second group of pixel units 150b are both in the darkest state). For example, during the first period, the first data signal can be transmitted to the first color pixel unit R-1, the second color pixel unit G-1, and the third color pixel unit B of the first group of pixel units 140b, but not to the first color pixel unit R-2 and the second color pixel unit G-2 of the second group of pixel units 150b. The first color pixel unit R-2 and the second color pixel unit G-2 of the second group of pixel units 150b can receive the signal of the darkest grayscale image from the source driver 120. Therefore, the first color pixel unit R-2 and the second color pixel unit G-2 of the second group of pixel units 150b both display black. The first data signal can be transmitted to the first to third color pixel units R-1, G-1, and B of the first group of pixel units 140b so that at least a portion of the first group of pixel units 140b is in a grayscale state different from that of the first color pixel unit R-2 and the second color pixel unit G-2 of the second group of pixel units 150b (e.g., at least a portion of the first group of pixel units 140b is in a bright state), but this is not a limitation. Figure 13In display state S1, the first color pixel unit R-2 and the second color pixel unit G-2 of the second group of pixel units 150b are both displayed as black, represented by a dotted pattern. On the other hand, in the second period (display state S2), the second group of pixel units 150b receives a second data signal (or a second screen signal) to display the corresponding screen. Specifically, in the second period, the second data signal is transmitted to the second group of pixel units 150b (i.e., the first color pixel unit R-2, the second color pixel unit G-2, and the third color pixel unit B) to display the corresponding screen, while the first color pixel unit R-1 and the second color pixel unit G-1 of the first group of pixel units 140b are both displayed as black (i.e., the first color pixel unit R-1 and the second color pixel unit G-1 of the first group of pixel units 140b are both in the darkest state). For example, during the second period, the second data signal can be transmitted to the first color pixel unit R-2, the second color pixel unit G-2, and the third color pixel unit B of the second group of pixel units 150b, but not to the first color pixel unit R-1 and the second color pixel unit G-1 of the first group of pixel units 140b. The first color pixel unit R-1 and the green pixel unit G-1 of the first group of pixel units 140b can receive the signal of the darkest grayscale image from the source driver 120. Therefore, the first color pixel unit R-1 and the second color pixel unit G-1 of the first group of pixel units 140b both display black. The second data signal can be transmitted to the first to third color pixel units R-2, G-2, and B of the second group of pixel units 150b so that at least a portion of the second group of pixel units 150b is in a grayscale state different from that of the first color pixel unit R-1 and the second color pixel unit G-1 of the first group of pixel units 140b (e.g., at least a portion of the second group of pixel units 150b is in a bright state), but is not limited thereto. Figure 13 In display state S2, the first color pixel unit R-1 and the second color pixel unit G-1 of the first group of pixel units 140b are both displayed as black, represented by a dotted pattern. For example... Figure 13As shown, the third color pixel unit B receives the first data signal and the second data signal during the first and second periods, respectively. In other words, the second color pixel unit G-1 in the first group of sub-pixels 140b is different from the second color pixel unit G-2 in the second group of pixel units 150b, and the first color pixel unit R-1 in the first group of pixel units 140b is different from the first color pixel unit R-1 in the second group of pixel units 150b, but the third color pixel unit B in the first group of pixel units 140b is the same as the third color pixel unit B in the second group of pixel units 150b. During the first period, both the first color pixel unit R-2 and the second color pixel unit G-2 of the second group of pixel units 150b display black, but the third color pixel unit B, which is shared by the first and second groups of pixel units 140b and 150b, receives the first data signal to display a portion of the corresponding image. During the second period, the first color pixel unit R-1 and the second color pixel unit G-1 of the first group of pixel units 140b both display black, but the third color pixel unit B, which is shared by the first and second groups of pixel units 140b and 150b, receives the first data signal to display a portion of the corresponding image.

[0074] In a variation embodiment, the display panel 130 may also be a normally white display panel. Unlike a normally black display panel, during the first period (display state S1), the first and second color pixel units R-2 and G-2 of the second group of pixel units 150b display the first and second colors respectively (specifically, the first and second color pixel units R-2 and G-2 of the second group of pixel units 150b are both in their brightest state), and the first data signal is transmitted to the first group of pixel units 140b (i.e., the first color pixel unit R-1, the second color pixel unit G-1, and the third color pixel unit B) to display the corresponding image; while during the second period (display state S2), the first and second color pixel units R-1 and G-1 of the first group of pixel units 140b display the first and second colors respectively (specifically, the first and second color pixel units R-1 and G-1 of the first group of pixel units 140b are both in their brightest state), and the second data signal is transmitted to the second group of pixel units 150 (i.e., the first color pixel unit R-2, the second color pixel unit G-2, and the third color pixel unit B) to display the corresponding image. For example, during the first period (display state S1), the first data signal can be transmitted to the first color pixel unit R-1, the second color pixel unit G-1, and the third color pixel unit B of the first group of pixel units 140b, but not to the first and second color pixel units R-2 and G-2 of the second group of pixel units 150b. The first and second color pixel units R-2 and G-2 of the second group of pixel units 150b can receive the signal of the brightest grayscale image from the source driver 120 to display the first color and the second color respectively. The first data signal can be transmitted to the first to third color pixel units R-1, G-1, and B of the first group of pixel units 140b so that at least a portion of the first group of pixel units 140b is in a grayscale state different from that of the first and second color pixel units R-2 and G-2 of the second group of pixel units 150b (for example, at least a portion of the first group of pixel units 140b is in a brighter grayscale). (low grayscale state); during the second period (display state S2), the second data signal can be transmitted to the first color pixel unit R-2, the second color pixel unit G-2 and the third color pixel unit B of the second group of pixel units 150b, but not to the first and second color pixel units R-1 and G-1 of the first group of pixel units 140b. The first and second color pixel units R-1 and G-1 of the first group of pixel units 140b can receive the signal of the brightest grayscale image from the source driver 120 to display the first color and the second color respectively. The second data signal can be transmitted to the first to third color pixel units R-2, G-2 and B of the second group of pixel units 150b so that at least a portion of the second group of pixel units 150b is in a grayscale state different from that of the first group of pixel units 140b (for example, at least a portion of the second group of pixel units 150b is in a grayscale state lower than the brightest grayscale), but is not limited thereto.

[0075] In the third embodiment, since the blue pixel unit has lower transmittance and less impact on image retention, the first group of pixel units 140b and the second group of pixel units 150b share the blue pixel unit (i.e., the third color pixel unit B), and the blue pixel unit receives the corresponding data signal during each frame to display a portion of the corresponding frame. Furthermore, in this embodiment, the proportion of blue pixel units is reduced, and the proportion of red and green pixel units (such as the first and second color pixel units R and G) is increased (i.e., the number of the first color pixel units R and the second color pixel units G in the display panel 130 is increased, and the number of the third color pixel units B is decreased). The first color pixel units R and the second color pixel units G are divided into two groups to alternately receive data signals during different frame periods.

[0076] [Fourth Embodiment]

[0077] Figure 14 It is illustrated according to the fourth embodiment. Figure 1 A schematic diagram of some pixel units on the display panel. Please refer to... Figure 1 and Figure 14In this embodiment, the display panel 130 contains only one color pixel unit (i.e., the fourth color pixel unit W), meaning that the pixel units PU of the display panel 130 either do not have a color filter layer or all have a color filter layer of the same color. In this embodiment, all pixel units PU are divided into two groups, referred to as the first group of pixel units 140c and the second group of pixel units 150c, and each group of pixel units includes multiple pixel units PU. In this embodiment, the first group of pixel units 140c includes multiple fourth color pixel units W-1, and the second group of pixel units 150c includes multiple fourth color pixel units W-2. In this embodiment, the pixel units PU in the first group of pixel units 140c are different from the pixel units PU in the second group of pixel units 150c; that is, the first group of pixel units 140c and the second group of pixel units 150c do not share pixel units PU. Two adjacent pixel units PU in the same column belong to different groups of pixel units, and two adjacent pixel units PU in the same row belong to different groups of pixel units. For example, two fourth-color pixel units W-1 and W-2 located at the intersection of pixel unit row R(j) and pixel unit columns C(i) and C(i+1) belong to the first group of pixel units 140c and the second group of pixel units 150c, respectively, while two fourth-color pixel units W-2 and W-1 located at the intersection of pixel unit row R(j+1) and pixel unit columns C(i) and C(i+1) belong to the second group of pixel units 150c and the first group of pixel units 140c, respectively. In this embodiment, one pixel unit PU is one pixel. For example, the display panel 130 may be a monochrome display panel, and the pixel unit PU may be a white pixel unit, but is not limited thereto. A white pixel unit may, for example, be a pixel unit without a color filter layer or a pixel unit with a white filter layer.

[0078] Figure 15 yes Figure 14 The diagram shows that the fourth color pixel unit is a white pixel unit. Figure 16 yes Figure 15 A diagram illustrating the subpixels during the first and second frame periods. Please refer to... Figure 1 and Figures 14-16 The fourth color pixel unit W can be a white pixel unit, but the color of the fourth color pixel unit W is not limited to this. It should be noted that... Figure 16 In this embodiment, the display panel 130 is a normally black display panel. Figure 16The illustration shows the display state S1 of some pixel units of the display panel 130 during a first period and the display state S2 during a second period. The display panel 130 displays a first image and a second image during the first period and the second period, respectively. During the first period, the display panel 130 receives a first data signal from the source driver 120. Specifically, the first data signal is transmitted to the fourth color pixel unit W-1 of the first group of pixel units 140c to display the corresponding image, while each fourth color pixel unit W-2 of the second group of pixel units 150c displays black (specifically, each fourth color pixel unit W-2 of the second group of pixel units 150c is in the darkest state). For example, during the first period, a first data signal may be transmitted to the first group of pixel units 140c but not to the second group of pixel units 150c. The fourth color pixel unit W-2 of the second group of pixel units 150c may receive the signal of the darkest grayscale image from the source driver 120. Therefore, each fourth color pixel unit W-2 of the second group of pixel units 150c displays black. The first data signal may be transmitted to the fourth color pixel unit W-1 of the first group of pixel units 140c so that at least a portion of the first group of pixel units 140c is in a grayscale state different from that of the second group of pixel units 150c (e.g., at least a portion of the first group of pixel units 140c is in a bright state), but this is not a limitation. Figure 16 In display state S1, the fourth color pixel unit W-2 of the second group of pixel units 150c is displayed as black, represented by a dotted pattern. During the second period, the display panel 130 receives a second data signal from the source driver 120. Specifically, during the second period, the second data signal is transmitted to the fourth color pixel unit W-2 of the second group of pixel units 150c to display the corresponding image, while each fourth color pixel unit W-1 of the first group of pixel units 140c displays black (specifically, each fourth color pixel unit W-1 of the first group of pixel units 140c is in the darkest state). For example, during the second period, a second data signal may be transmitted to the second group of pixel units 150c but not to the first group of pixel units 140c. The fourth color pixel unit W-1 of the first group of pixel units 140c may receive the signal of the darkest grayscale image from the source driver 120. Therefore, each fourth color pixel unit W-1 of the first group of pixel units 140c displays black. The second data signal may be transmitted to the fourth color pixel unit W-2 of the second group of pixel units 150c to cause at least a portion of the second group of pixel units 150c to be in a grayscale state different from that of the first group of pixel units 140c (e.g., at least a portion of the second group of pixel units 150c is in a bright state), but is not limited thereto. Figure 16 In display state S2, the fourth color pixel unit W-1 of the first group of pixel units 140c is displayed as black, represented by a dot pattern.

[0079] In a variation embodiment, the display panel 130 may also be a normally white display panel. Unlike a normally black display panel, during the first period (display state S1), each fourth color pixel unit W-2 of the second group of pixel units 150c displays the fourth color (specifically, each fourth color pixel unit W-2 of the second group of pixel units 150c is in its brightest state), and a first data signal is transmitted to the fourth color pixel unit W-1 of the first group of pixel units 140c to display the corresponding image; while during the second period (display state S2), each fourth color pixel unit W-1 of the first group of pixel units 140c displays the fourth color (specifically, each fourth color pixel unit W-1 of the first group of pixel units 140c is in its brightest state), and a second data signal is transmitted to the fourth color pixel unit W-2 of the second group of pixel units 150c to display the corresponding image. For example, during the first period (display state S1), a first data signal can be transmitted to the first group of pixel units 140c but not to the second group of pixel units 150c. The fourth color pixel unit W-2 of the second group of pixel units 150c can receive the signal of the brightest grayscale from the source driver 120 to display the fourth color. The first data signal can be transmitted to the fourth color pixel unit W-1 of the first group of pixel units 140c so that at least a portion of the first group of pixel units 140c is in a grayscale state different from that of the second group of pixel units 150c (e.g., at least a portion of the first group of pixel units 140c is in a grayscale state lower than the brightest grayscale). While... During the second period (display state S2), the second data signal can be transmitted to the second group of pixel units 150c but not to the first group of pixel units 140c. The fourth color pixel unit W-1 of the first group of pixel units 140c can receive the signal of the brightest grayscale image from the source driver 120 to display the fourth color. The second data signal can be transmitted to the fourth color pixel unit W-2 of the second group of pixel units 150c so that at least a portion of the second group of pixel units 150c is in a grayscale state different from that of the first group of pixel units 140c (for example, at least a portion of the second group of pixel units 150c is in a grayscale state lower than the brightest grayscale), but is not limited thereto.

[0080] [Fifth Embodiment]

[0081] Figure 17 It is illustrated according to the fifth embodiment. Figure 1 A schematic diagram of some pixel units on the display panel. Please refer to... Figure 1 and Figure 17In this embodiment, the display panel 130 includes pixel units of two colors (i.e., a fourth color pixel unit W and a fifth color pixel unit R'). In this embodiment, all pixel units PU are divided into two groups, referred to as the first group of pixel units 140d and the second group of pixel units 150d, and each group of pixel units includes multiple pixel units PU. In this embodiment, the first group of pixel units 140d includes multiple fourth color pixel units W-1 and multiple fifth color pixel units R'-1, and the second group of pixel units 150d includes multiple fourth color pixel units W-2 and multiple fifth color pixel units R'-2. In this embodiment, the pixel units PU in the first group of pixel units 140d are different from the pixel units PU in the second group of pixel units 150d; that is, the first group of pixel units 140d and the second group of pixel units 150d do not share pixel units PU. In this embodiment, pixel unit column C(i) is adjacent to pixel unit column C(i+1) (or pixel unit column C(i+4) and pixel unit column C(i+5); or pixel unit column C(i+8) and pixel unit column C(i+9)) and contains only fourth color pixel unit W; pixel unit column C(i+2) is adjacent to pixel unit column C(i+3) (or pixel unit column C(i+6) and pixel unit column C(i+7); or pixel unit column C(i+10) and pixel unit column C(i+11)) and contains only fifth color pixel unit R'. Furthermore, two adjacent pixel units PU in the same column also belong to different groups of pixel units. For example, the four pixel units PU located at the intersection of pixel unit columns C(i), C(i+1), C(i+2), C(i+3) and pixel unit row R(j) are respectively the fourth color pixel unit W-1 of the first group of pixel units 140d, the fourth color pixel unit W-2 of the second group of pixel units 150d, the fifth color pixel unit R'-1 of the first group of pixel units 140d, and the fifth color pixel unit R'-2 of the second group of pixel units 150d. Meanwhile, the four pixel units PU located at the intersection of pixel unit columns C(i), C(i+1), C(i+2), C(i+3) and pixel unit row R(j+1) are respectively the fourth color pixel unit W-2 of the second group of pixel units 150d, the fourth color pixel unit W-1 of the first group of pixel units 140d, the fifth color pixel unit R'-2 of the second group of pixel units 150d, and the fifth color pixel unit R'-1 of the first group of pixel units 140d. It should be noted that in Figure 17 In some embodiments, the ratio of the number of fourth color pixel units W to the number of fifth color pixel units R' is 1:1, but this is not a limitation. For example, in some embodiments, the ratio of the number of fourth color pixel units W to the number of fifth color pixel units R' may be 8:2 (e.g., 8 columns of fourth color pixel units, 2 columns of fifth color pixel units, 8 columns of fourth color pixel units, 2 columns of fifth color pixel units, etc. are arranged sequentially).

[0082] Figure 18 yes Figure 17 The fourth and fifth color sub-pixels are white and red pixel units, respectively. Figure 19 yes Figure 17 A schematic diagram of pixel units during the first frame and the second frame. Please refer to... Figure 1 and Figures 18-19 The fourth color pixel unit W and the fifth color pixel unit R' can be a white pixel unit and a red pixel unit, respectively, but the colors of the fourth color pixel unit W and the fifth color pixel unit R' are not limited to these. It should be noted that in... Figure 19 In this embodiment, the display panel 130 is a normally black display panel. Please refer to... Figure 1 and Figures 17-19 .like Figure 19 As shown, Figure 19 The illustration shows the display state S1 of some pixel units of the display panel 130 during a first period and the display state S2 during a second period (or second screen period), wherein the display panel 130 displays a first screen and a second screen during the first period and the second period, respectively. During the first period, the display panel 130 receives a first data signal from the source driver 120. Specifically, the first data signal is transmitted to the fourth and fifth color pixel units W-1 and R'-1 of the first group of pixel units 140d to display the corresponding screen, while the fourth and fifth color pixel units W-2 and R'-2 of the second group of pixel units 150d are both displayed as black (specifically, the fourth and fifth color pixel units W-2 and R'-2 of the second group of pixel units 150d are both in the darkest state). For example, during the first period, a first data signal may be transmitted to the first group of pixel units 140d but not to the second group of pixel units 150d. The fourth and fifth color pixel units W-2 and R'-2 of the second group of pixel units 150d may receive the signal of the darkest grayscale image from the source driver 120. Therefore, the fourth and fifth color pixel units W-2 and R'-2 of the second group of pixel units 150d both display black. The first data signal may be transmitted to the fourth and fifth color pixel units W-1 and R'-1 of the first group of pixel units 140d so that at least a portion of the first group of pixel units 140d is in a grayscale state different from that of the second group of pixel units 150d (e.g., at least a portion of the first group of pixel units 140d is in a bright state), but this is not a limitation. Figure 19In display state S1, the fourth and fifth color pixel units W-2 and R'-2 of the second group of pixel units 150d are displayed as black, represented by a dotted pattern. During the second period, the display panel 130 receives a second data signal from the source driver 120. Specifically, during the second period, the second data signal is transmitted to the fourth and fifth color pixel units W-2 and R'-2 of the second group of pixel units 150d to display the corresponding image, while the fourth and fifth color pixel units W-1 and R'-1 of the first group of pixel units 140d are both displayed as black (specifically, the pixel units W-1 and R'-1 of the first group of pixel units 140d are both in the darkest state). For example, during the second period, a second data signal may be transmitted to the second group of pixel units 150d but not to the first group of pixel units 140d. The fourth and fifth color pixel units W-1 and R'-1 of the first group of pixel units 140d may receive the signal of the darkest grayscale image from the source driver 120. Therefore, the fourth and fifth color pixel units W-1 and R'-1 of the first group of pixel units 140d both display black. The second data signal may be transmitted to the fourth and fifth color pixel units W-2 and R'-2 of the second group of pixel units 150d so that at least a portion of the second group of pixel units 150d is in a grayscale state different from that of the first group of pixel units 140d (e.g., at least a portion of the second group of pixel units 150d is in a bright state), but this is not a limitation. Figure 19 In display state S2, the fourth and fifth color pixel units W-1 and R'-1 of the first group of pixel units 140d are displayed in black, represented by a dotted pattern.

[0083] In a variation embodiment, the display panel 130 can also be a normally white display panel. Unlike a normally black display panel, during the first period (display state S1), the fourth and fifth color pixel units W-2 and R'-2 of the second group of pixel units 150d display the fourth and fifth colors respectively (specifically, the fourth and fifth color pixel units W-2 and R'-2 of the second group of pixel units 150d are both in their brightest state), and a first data signal is transmitted to the fourth and fifth color pixel units W-1 and R'-1 of the first group of pixel units 140d to display the corresponding image; while during the second period (display state S2), the fourth and fifth color pixel units W-1 and R'-1 of the first group of pixel units 140d display the fourth and fifth colors respectively (specifically, the fourth and fifth color pixel units W-1 and R'-1 of the first group of pixel units 140d are both in their brightest state), and a second data signal is transmitted to the fourth and fifth color pixel units W-2 and R'-2 of the second group of pixel units 150d to display the corresponding image. For example, during the first period (display state S1), the first data signal can be transmitted to the first group of pixel units 140d but not to the second group of pixel units 150d. The fourth and fifth color pixel units W-2 and R'-2 of the second group of pixel units 150d can receive the signal of the brightest grayscale from the source driver 120 to display the fourth and fifth colors respectively. The first data signal can be transmitted to the fourth and fifth color pixel units W-1 and R'-1 of the first group of pixel units 140d so that at least a portion of the first group of pixel units 140d is in a grayscale state different from that of the second group of pixel units 150d (e.g., at least a portion of the first group of pixel units 140d is in a grayscale state lower than the brightest grayscale). During the second period (display state S2), the second data signal can be transmitted to the second group of pixel units 150d but not to the first group of pixel units 140d. The fourth and fifth color pixel units W-1 and R'-1 of the first group of pixel units 140d can receive the signal of the brightest grayscale image from the source driver 120 to display the fourth and fifth colors respectively. The second data signal can be transmitted to the fourth and fifth color pixel units W-2 and R'-2 of the second group of pixel units 150d so that at least a portion of the second group of pixel units 150d is in a grayscale state different from that of the first group of pixel units 140d (for example, at least a portion of the second group of pixel units 150d is in a grayscale state lower than the brightest grayscale), but not limited thereto.

[0084] Because electronic tags sometimes use special colors to make certain parts of the content more eye-catching, for example, taking electronic tags applied to shelves as an example, the display device of this embodiment can display the discount price in the screen of the electronic tag in a more eye-catching color (such as red) (such as the fifth color pixel unit R'-1 of the first group of pixel units 140d or the fifth color pixel unit R'-2 of the second group of pixel units 150d in this embodiment) to attract consumers, while the rest of the screen is displayed in black and white (such as the fourth color pixel unit W-1 of the first group of pixel units 140d or the fourth color pixel unit W-2 of the second group of pixel units 150d in this embodiment), but is not limited thereto.

[0085] In the above embodiment, the display panel includes two sets of pixel units. When displaying different images, different sets of pixel units are switched. This alternating driving of pixel units can avoid the cumulative ions from affecting the display image and prevent the generation of afterimages in the image.

[0086] Although the present invention has been disclosed above by way of embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the appended claims.
