Description

Technical Field

[0001] This application relates to the field of displays, specifically to a display panel and a display device. Background Technology

[0002] In the production process of flexible OLED panels, short circuit faults may occur between adjacent data lines. Existing detection methods have difficulty effectively detecting short circuit faults between data lines of adjacent sub-pixels of the same color, which may lead to faulty display panels entering subsequent processes and causing unnecessary waste of testing resources.

[0003] Therefore, how to effectively detect short circuit faults in the data lines between adjacent sub-pixels of the same color has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] This application provides a display panel and display device that can effectively detect short-circuit faults between data lines connected to adjacent light-emitting sub-pixels of the same color.

[0005] In a first aspect, embodiments of this application provide a display panel, including: a plurality of light-emitting sub-pixels arranged in an array, a plurality of first data lines, and a plurality of second data lines. The plurality of light-emitting sub-pixels include odd-numbered rows of first light-emitting sub-pixels of a first color and even-numbered rows of second light-emitting sub-pixels of a first color; the first data lines are connected to the first light-emitting sub-pixels in the same column; the second data lines are connected to the second light-emitting sub-pixels in the same column; during the image detection stage, the first data lines and the second data lines are used to provide different data signals.

[0006] Secondly, embodiments of this disclosure also provide a display device, including a display panel as described in the first aspect embodiment.

[0007] According to an embodiment of this application, the array of multiple light-emitting sub-pixels includes first light-emitting sub-pixels in odd-numbered rows and second light-emitting sub-pixels in even-numbered rows. Both the first and second light-emitting sub-pixels are light-emitting sub-pixels of a first color. During the image detection phase, multiple first data lines and multiple second data lines provide different data signals to the first and second light-emitting sub-pixels in the same column, respectively. When a short circuit fault occurs between a first data line and an adjacent second data line, the data signal output by the first data line will be interfered with by the second data line, or vice versa. This affects the display brightness of a column of first light-emitting sub-pixels connected to the first data line or a column of second light-emitting sub-pixels connected to the second data line. Therefore, a short circuit fault between the first and second data lines can be directly observed during the image detection phase, thereby effectively detecting short circuit faults between data lines connecting adjacent light-emitting sub-pixels of the same color.

[0024] This application provides a display panel and a display device. The embodiments of this application will be described below with reference to the accompanying drawings.

[0025] Figure 1 This illustration shows a schematic diagram of a display panel provided in one embodiment of the present application, such as... Figure 1 As shown, the display panel includes: multiple light-emitting sub-pixels arranged in an array, multiple first data lines 21, and multiple second data lines 22.

[0026] Multiple luminous sub-pixels include a first luminous sub-pixel 11 in odd-numbered rows and a second luminous sub-pixel 12 in even-numbered rows. Both the first luminous sub-pixel 11 and the second luminous sub-pixel 12 are luminous sub-pixels of the first color. A first data line 21 is connected to the first luminous sub-pixel 11 in the same column, and a second data line 22 is connected to the second luminous sub-pixel 12 in the same column.

[0027] Specifically, the first data line 21 and the second data line 22 are alternately arranged. A single first data line 21 is connected to a first luminous sub-pixel 11 in the same column. Multiple first data lines 21 can connect all columns of first luminous sub-pixels 11 in odd-numbered rows, so that when the first data line 21 outputs a data signal, all first luminous sub-pixels 11 in odd-numbered rows are lit. A single second data line 22 is connected to a second luminous sub-pixel 12 in the same column. Multiple second data lines 22 can connect all columns of second luminous sub-pixels 12 in even-numbered rows, so that when the second data line 22 outputs a data signal, all second luminous sub-pixels 12 in even-numbered rows are lit.

[0028] During the image detection phase, the first data line 21 and the second data line 22 provide different data signals. When all the first data lines 21 provide data signals, each first luminous sub-pixel 11 in the odd-numbered rows is illuminated. The second data lines 22 provide different data signals, causing each second luminous sub-pixel 12 in the even-numbered rows to display at different brightness levels. At this time, the entire display panel displays the first color image. When all the second data lines 22 provide data signals, each second luminous sub-pixel 12 in the even-numbered rows is illuminated. The first data lines 21 provide different data signals, causing each first luminous sub-pixel 11 in the odd-numbered rows to display at different brightness levels. At this time, the entire display panel also displays the first color image.

[0029] As an example, when only the driving circuit of the first light-emitting sub-pixel 11 is enabled, the first data line 21 and the second data line 22 output different data signals. Since only the driving circuit of the first light-emitting sub-pixel 11 is enabled, in order for the display panel to emit light normally, the first data line 21 only needs to provide a data signal for lighting up, and the second data line 22 outputs a data signal with a voltage different from the lighting data signal. At this time, only the first light-emitting sub-pixel 11 is lit up, and the second light-emitting sub-pixel 12 remains dark. If a short circuit occurs between a first data line 21 and an adjacent second data line 22, the data signal provided by the first data line 21 will be interfered with by the second data line 22, and the data signal provided by the second data line 22 will also be interfered with by the first data line 21. When the voltage of the data signal provided by the second data line 22 is greater than the voltage of the data signal provided by the first data line 21, the voltage of the data signal provided by the faulty first data line 21 to the corresponding column of first light-emitting sub-pixels 11 will increase, thereby reducing the brightness of this column of first light-emitting sub-pixels 11, thus causing a dark line to appear in the display panel displaying the first color image.

[0030] As another example, when only the driving circuit of the second light-emitting sub-pixel 12 is enabled, the first data line 21 and the second data line 22 output different data signals. Since only the driving circuit of the second light-emitting sub-pixel 12 is enabled, in order for the display panel to emit light normally, the second data line 22 only needs to provide a data signal for lighting up. The first data line 21 outputs a data signal with a voltage different from the lighting data signal. At this time, only the second light-emitting sub-pixel 12 is lit up, and the first light-emitting sub-pixel 11 remains dark. If a short circuit occurs between a first data line 21 and an adjacent second data line 22, the data signal provided by the first data line 21 will be interfered with by the second data line 22, and the data signal provided by the second data line 22 will also be interfered with by the first data line 21. When the voltage of the data signal provided by the first data line 21 is greater than the voltage of the data signal provided by the second data line 22, the voltage of the data signal provided by the faulty second data line 22 to the corresponding column of second light-emitting sub-pixels 12 will increase, thereby reducing the brightness of this column of second light-emitting sub-pixels 12, thus causing a dark line to appear in the display panel displaying the first color image.

[0031] According to an embodiment of this application, the array of multiple light-emitting sub-pixels includes first light-emitting sub-pixels 11 in odd-numbered rows and second light-emitting sub-pixels 12 in even-numbered rows. During the image detection phase, multiple first data lines 21 and multiple second data lines 22 provide different data signals to the first light-emitting sub-pixels 11 and the second light-emitting sub-pixels 12 in the same column, respectively. When a short circuit occurs between a first data line 21 and an adjacent second data line 22, the data signal output by the first data line 21 is interfered with by the second data line 22, or vice versa. This affects the display brightness of a column of first light-emitting sub-pixels 11 connected to the first data line 21 or a column of second light-emitting sub-pixels 12 connected to the second data line 22. Therefore, a short circuit can be directly observed between the first data line 21 and the second data line 22 during the image detection phase, thereby enabling effective detection of short circuits between data lines connecting adjacent light-emitting sub-pixels of the same color.

[0032] In some embodiments, during the image detection phase, one of the first data line and the second data line provides a lighting data signal, and the other provides a dark state data signal; wherein, the lighting data signal is used to light up the light-emitting sub-pixels, and the dark state data signal is used to drive the light-emitting sub-pixels to remain in a dark state.

[0033] For example, the signal voltage for the lit data signal is 3V, and the signal voltage for the black data signal is 7V. Figure 2 This illustration shows a timing diagram of a display panel provided in one embodiment of the present application, such as... Figure 2 As shown, during the progressive scan process, in time period T1, the data fan-out line is connected to the first data line via a multiplexing module, providing a 3V lighting data signal. In time period T2, the data fan-out line is connected to the second data line via a multiplexing module, providing a 7V black state data signal. The data fan-out line can be connected to either the first or second data line via the multiplexing module, and the data signal provided by the data fan-out line can be transmitted via either the first or second data line.

[0034] When the first data line provides the illumination data signal and the driving circuits of all first light-emitting sub-pixels are enabled, all first light-emitting sub-pixels will be illuminated, and the display panel will display the first color image. If a short circuit fault occurs between a first data line and an adjacent second data line, the voltage of the illumination data signal output by the first data line and the voltage of the black state data signal output by the second data line will change. For example, if both the first and second data lines that have experienced a short circuit fault output a voltage of 5V, the signal voltage received by the column of first light-emitting sub-pixels connected to the faulty first data line will increase from 3V to 5V, thereby reducing the brightness of this column of first light-emitting sub-pixels, resulting in a dark line with a lower brightness than other areas of the display panel.

[0035] When the second data line provides the illumination data signal and the driving circuits of all second light-emitting sub-pixels are enabled, all second light-emitting sub-pixels will be illuminated, and the display panel will display the first color image. If a short circuit fault occurs between a second data line and an adjacent first data line, the voltage of the illumination data signal output by the second data line and the voltage of the black state data signal output by the first data line will change. For example, both the first and second data lines that have experienced a short circuit fault may output a voltage of 5V. At this time, the signal voltage received by a column of second light-emitting sub-pixels connected to the faulty second data line increases from 3V to 5V, thereby reducing the brightness of this column of second light-emitting sub-pixels, resulting in a dark line with a lower brightness than other areas of the display panel. Therefore, during the image detection stage, by observing whether a dark line appears on the display panel, it is possible to visually observe whether a short circuit fault has occurred between the first and second data lines, thereby effectively detecting short circuit faults between data lines connecting adjacent light-emitting sub-pixels of the same color.

[0036] It should be noted that the signal voltage for the lit data signal is 3V and the signal voltage for the black data signal is 7V. These are just examples. The specific signal voltage settings need to be determined according to the actual situation, and no specific limit is made here.

[0037] In some embodiments, Figure 3 This illustration shows another structural diagram of a display panel provided in one embodiment of the present application, such as... Figure 3 As shown, the display panel also includes a plurality of first scan signal lines 31 and a plurality of second scan signal lines 32.

[0038] The first scan signal line 31 is connected to the first light-emitting sub-pixel 11 in the same row; the second scan signal line 32 is connected to the second light-emitting sub-pixel 12 in the same row. In a single data frame, adjacent first scan signal lines 31 and 32 are used to provide a first valid pulse to the driving circuit of the first light-emitting sub-pixel 11 and a second valid pulse to the driving circuit of the second light-emitting sub-pixel 12, respectively. The first valid pulse can drive the first light-emitting sub-pixel in the same row to light up; the second valid pulse can drive the second light-emitting sub-pixel in the same row to light up.

[0039] Specifically, when the first scan signal line 31 provides the first valid pulse, the driving circuit of the first light-emitting sub-pixel 11 in the same row is enabled. At this time, as long as all the first data lines 21 connected to the first light-emitting sub-pixel 11 provide lighting data signals, the first light-emitting sub-pixel 11 is lit. As long as all the first data lines 21 connected to the first light-emitting sub-pixel 11 provide black state data signals, the first light-emitting sub-pixel 11 remains in a dark state.

[0040] When the second scan signal line 32 provides the second valid pulse, the driving circuit of the second light-emitting sub-pixel 12 in the same row is enabled. At this time, as long as all the second data lines 22 connected to the second light-emitting sub-pixel 12 provide lighting data signals, the second light-emitting sub-pixel 12 will be lit. If all the second data lines 22 connected to the second light-emitting sub-pixel 12 provide black state data signals, the second light-emitting sub-pixel 12 will remain in a dark state.

[0041] For example, Figure 4 This illustration shows another timing diagram of a display panel provided in one embodiment of the present application, such as... Figure 4As shown, the plurality of first scan signal lines 31 include SCAN1, SCAN3, and SCAN5. The plurality of second scan signal lines 32 include SCAN2, SCAN4, and SCAN6. Since the driving circuits of the first light-emitting sub-pixel 11 and the second light-emitting sub-pixel 12 are both active low, the first effective pulse and the second effective pulse are both low. In a single data frame, during the first time period t11, when SCAN1 provides the first effective pulse, SCAN2 remains high, and the remaining scan signal lines remain high; when SCAN2 provides the second effective pulse, SCAN1 remains high, and the remaining scan signal lines remain high. During the second time period t12, when SCAN3 provides the first effective pulse, SCAN4 remains high, and the remaining scan signal lines remain high; when SCAN4 provides the second effective pulse, SCAN3 remains high, and the remaining scan signal lines remain high. During the third time period t13, when SCAN5 provides the first valid pulse, SCAN6 remains high, and the remaining scan signal lines remain high; when SCAN6 provides the second valid pulse, SCAN5 remains high, and the remaining scan signal lines remain high.

[0042] During the image detection stage, in order to avoid the situation where the image problem of the display panel is not detected due to the simultaneous lighting of the first light-emitting sub-pixel 11 and the second light-emitting sub-pixel 12, it is necessary to detect the display status of the first light-emitting sub-pixel and the second light-emitting sub-pixel separately. Therefore, the first scan signal line 31 and the second scan signal line 32 will not output valid pulses at the same time, that is, the first valid pulse and the second valid pulse do not overlap.

[0043] This disclosure enables the first scanning signal line 31 and the second scanning signal line 32 to output effective pulses respectively. During the image detection phase, different data signals are output through the first data line 21 and the second data line 22, illuminating only the first light-emitting sub-pixel 11 or only the second light-emitting sub-pixel 12 on the display panel. Since the voltages of the data signals output by the first data line 21 and the second data line 22 are different at the same time, a short circuit between a first data line 21 and an adjacent second data line 22 will cause a change in the voltage of the data signals output by the short-circuited first data line 21 and the second data line 22. This changes the brightness of the connected column of first light-emitting sub-pixels 11 or second light-emitting sub-pixels 12, resulting in a clearly observable dark line on the entire display panel that is less bright than other areas. Therefore, during the image detection phase, observing the presence of dark lines on the display panel allows for direct observation of whether a short circuit has occurred between the first data line 21 and the second data line 22, thereby effectively detecting short circuits between data lines connecting adjacent light-emitting sub-pixels of the same color.

[0044] According to some embodiments of this application, optionally, see also: Figure 3 and Figure 4 Within the interval where the first scan signal line 31 provides the first valid pulse, the first data line 21 provides the lighting data signal; within the interval where the second scan signal line 32 provides the second valid pulse, the second data line 22 provides the black state data signal.

[0045] For example, when detecting the illumination status of the first light-emitting sub-pixel 11 in the display panel, during the first time period t11, SCAN1 provides a first valid pulse, and SCAN2 remains high. At this time, the first data line 21 provides an illumination data signal, and the second data line 22 provides a black state data signal. When SCAN1 remains high, SCAN2 provides a second valid pulse. At this time, the first data line 21 continues to provide an illumination data signal, and the second data line 22 provides a black state data signal. Therefore, it can be ensured that during the period when SCAN1 provides the first valid pulse, the first data line 21 provides an illumination data signal, enabling the first light-emitting sub-pixel 11 to illuminate during the light-emitting phase. The second light-emitting sub-pixel 12, however, does not receive a black state data signal because the second scan signal line 32 remains high. During the period when SCAN2 provides the second valid pulse, the first light-emitting sub-pixel 11 does not receive an illumination data signal because the first scan signal line 31 remains high, and the second light-emitting sub-pixel 12 also does not illuminate because the second data line 22 provides a black state data signal. Therefore, during the period when the illumination status of the first light-emitting sub-pixel 11 in the display panel can be detected, only the first light-emitting sub-pixel 11 is illuminated.

[0046] When a short circuit occurs between a first data line 21 and an adjacent second data line 22, the brightness of a column of first light-emitting sub-pixels 11 connected to the short-circuited first data line 21 will decrease, and a dark line with lower brightness than other areas of the display panel can be clearly observed across the entire screen. Therefore, during the screen detection phase, by observing whether a dark line appears on the display panel, it is possible to intuitively observe whether a short circuit has occurred between the first data line 21 and the second data line 22, thereby effectively detecting short circuits between data lines connecting adjacent light-emitting sub-pixels of the same color.

[0047] According to other embodiments of this application, optionally, see also: Figure 3 and Figure 4 Within the interval where the second scan signal line 32 provides the second valid pulse, the second data line 22 provides the lighting data signal; within the interval where the first scan signal line 31 provides the first valid pulse, the first data line 21 provides the black state data signal.

[0048] For example, when detecting the illumination status of the second light-emitting sub-pixel 12 in the display panel, during the first time period t11, SCAN1 provides a first valid pulse, and SCAN2 remains high. At this time, the first data line 21 provides a black state data signal, and the second data line 22 provides an illumination data signal. While SCAN1 remains high, SCAN2 provides a second valid pulse. At this time, the first data line 21 continues to provide a black state data signal, and the second data line 22 provides an illumination data signal. Therefore, it can be ensured that during the period when SCAN1 provides the first valid pulse, the first data line 21 provides a black state data signal, keeping the first light-emitting sub-pixel 11 in a dark state, while the second light-emitting sub-pixel 12 does not receive an illumination data signal because the second scan signal line 32 remains high. During the period when SCAN2 provides the second valid pulse, the second light-emitting sub-pixel 12 can illuminate during the light-emitting phase because the second data line 22 provides an illumination data signal, while the first light-emitting sub-pixel 11 does not receive a black state data signal because SCAN1 remains high. Therefore, during the period when the illumination status of the second light-emitting sub-pixel 12 in the display panel can be detected, only the second light-emitting sub-pixel 12 is illuminated.

[0049] When a short circuit occurs between a first data line 21 and an adjacent second data line 22, the brightness of a column of second light-emitting sub-pixels 12 connected to the short-circuited second data line 22 will decrease. A dark line with a lower brightness compared to other areas of the display panel can be clearly observed across the entire screen. Therefore, during the screen detection phase, by observing whether a dark line appears on the display panel, it is possible to intuitively observe whether a short circuit has occurred between the first data line 21 and the second data line 22, thereby effectively detecting short circuits between data lines connecting adjacent light-emitting sub-pixels of the same color.

[0050] In some embodiments, Figure 5 This illustration shows another structural diagram of a display panel provided in one embodiment of the present application, such as... Figure 5 As shown, the plurality of light-emitting sub-pixels also include a third light-emitting sub-pixel 13 of a second color and a fourth light-emitting sub-pixel 14 of a third color. The first color can be green, and the second and third colors can be red and blue, respectively.

[0051] When detecting the first luminous sub-pixel 11 or the second luminous sub-pixel 12 of the first color, the third luminous sub-pixel 13 and the fourth luminous sub-pixel 14 of the second color must both remain dark to avoid interfering with the first color image on the display panel. Specifically, the third luminous sub-pixel 13 in odd-numbered rows, the fourth luminous sub-pixel 14 in odd-numbered rows, the first luminous sub-pixel 11, the second luminous sub-pixel 12, the third luminous sub-pixel 13 in even-numbered rows, and the fourth luminous sub-pixel 14 in even-numbered rows are arranged sequentially.

[0052] In some embodiments, see continue to see Figure 5 The display panel also includes multiple third scan signal lines 33 and multiple fourth scan signal lines 34.

[0053] The third scan signal line 33 is connected to the third light-emitting sub-pixel 13 in the odd-numbered rows and the fourth light-emitting sub-pixel 14 in the even-numbered rows of the two adjacent rows; the fourth scan signal line 34 is connected to the third light-emitting sub-pixel 13 in the even-numbered rows and the fourth light-emitting sub-pixel 14 in the odd-numbered rows of the two adjacent rows.

[0054] The third scan signal line 33 is used to provide a third valid pulse, and the fourth scan signal line 34 is used to provide a fourth valid pulse; the third valid pulse is used to drive the third light-emitting sub-pixel 13 in odd-numbered rows and the fourth light-emitting sub-pixel 14 in even-numbered rows; the fourth valid pulse is used to drive the third light-emitting sub-pixel 13 in even-numbered rows and the fourth light-emitting sub-pixel 14 in odd-numbered rows.

[0055] Specifically, Figure 6 This illustration shows another timing diagram of a display panel provided in one embodiment of the present application, such as... Figure 6 As shown, since the driving circuits of the first light-emitting sub-pixel 11, the second light-emitting sub-pixel 12, the third light-emitting sub-pixel 13, and the fourth light-emitting sub-pixel 14 are all active at low level, the first effective pulse, the second effective pulse, the third effective pulse, and the fourth effective pulse are all at low level.

[0056] During the third time period t21, the first scan signal line 31 provides a first valid pulse, while the second scan signal line 32, the third scan signal line 33, and the fourth scan signal line 34 all remain at a high level. At this time, the first light-emitting sub-pixel 11 connected to the first scan signal line 31 can be set to a bright or dark state, while the second light-emitting sub-pixel 12, the third light-emitting sub-pixel 13, and the fourth light-emitting sub-pixel 14 remain in a dark state. Therefore, this disclosure allows the first light-emitting sub-pixel 11 to be set to a bright state when the first scan signal line 31 provides a first valid pulse, and all light-emitting sub-pixels to remain in a dark state when other scan signal lines provide valid pulses. This achieves that during image detection of the first color light-emitting sub-pixels in odd-numbered rows, the display panel only displays the first color.

[0057] During the fourth time period t22, the fourth scan signal line 34 provides a fourth valid pulse, while the first scan signal line 31, the second scan signal line 32, and the third scan signal line 33 all remain at a high level. At this time, the even-numbered rows of third luminous sub-pixels 13 and the odd-numbered rows of fourth luminous sub-pixels 14 connected to the fourth scan signal line 34 can be set to a bright state or a dark state, respectively, while the first luminous sub-pixel 11, the second luminous sub-pixel 12, the odd-numbered rows of third luminous sub-pixels 13, and the even-numbered rows of fourth luminous sub-pixels 14 remain in a dark state. Therefore, this disclosure allows the even-numbered rows of third luminous sub-pixels 13 to be set to a bright state and the odd-numbered rows of fourth luminous sub-pixels 14 to remain in a dark state when the fourth scan signal line 34 provides the fourth valid pulse, thereby enabling the display panel to display only the second color during image detection of the second color's luminous sub-pixels. Alternatively, when the fourth scan signal line 34 provides the fourth valid pulse, the third light-emitting sub-pixel 13 in the even-numbered rows is set to a dark state, while the fourth light-emitting sub-pixel 14 in the odd-numbered rows remains in a bright state, thereby enabling the display panel to display only the third color during the image detection of the light-emitting sub-pixels of the third color.

[0058] During the fifth time period t23, the second scan signal line 32 provides a second valid pulse, while the first scan signal line 31, the third scan signal line 33, and the fourth scan signal line 34 all remain at a high level. At this time, the second light-emitting sub-pixel 12 connected to the second scan signal line 32 can be set to a bright or dark state, while the first light-emitting sub-pixel 11, the third light-emitting sub-pixel 13, and the fourth light-emitting sub-pixel 14 remain in a dark state. Therefore, this disclosure allows the second light-emitting sub-pixel 12 to be set to a bright state when the second scan signal line 32 provides a second valid pulse, and all light-emitting sub-pixels to remain in a dark state when other scan signal lines provide valid pulses. This achieves that during image detection of the first color light-emitting sub-pixels in even-numbered rows, the display panel only displays the first color.

[0059] During the sixth time period t24, the third scan signal line 33 provides a third valid pulse, while the first scan signal line 31, the second scan signal line 32, and the fourth scan signal line 34 all remain at a high level. At this time, the third luminous sub-pixels 13 in odd-numbered rows and the fourth luminous sub-pixels 14 in even-numbered rows connected to the third scan signal line 33 can be set to a bright state or a dark state, respectively, while the first luminous sub-pixels 11, the second luminous sub-pixels 12, the third luminous sub-pixels 13 in even-numbered rows, and the fourth luminous sub-pixels 14 in odd-numbered rows remain in a dark state. Therefore, this disclosure allows the third luminous sub-pixels 13 in odd-numbered rows to be set to a bright state and the fourth luminous sub-pixels 14 in even-numbered rows to remain in a dark state when the third scan signal line 33 provides the third valid pulse, thereby enabling the display panel to display only the second color during image detection of the luminous sub-pixels of the second color. Alternatively, when the third scan signal line 33 provides the third valid pulse, the third light-emitting sub-pixel 13 in the odd-numbered rows is set to a dark state, while the fourth light-emitting sub-pixel 14 in the even-numbered rows remains in a bright state, thereby enabling the display panel to display only the third color during the image detection of the light-emitting sub-pixels of the second color.

[0060] In some embodiments, see continue to see Figure 5 In the same column, the third light-emitting sub-pixels 13 in odd-numbered rows are connected to the corresponding first data line 21, and the third light-emitting sub-pixels 13 in even-numbered rows are connected to the corresponding second data line 22; in the same column, the fourth light-emitting sub-pixels 14 in odd-numbered rows are connected to the corresponding first data line 21, and the fourth light-emitting sub-pixels 14 in even-numbered rows are connected to the corresponding second data line 22.

[0061] For example, during the image detection phase, when image detection is performed on the third luminous sub-pixel 13, when the third scan signal line 33 provides the third valid pulse, the first data line 21 provides a lighting data signal, enabling the third luminous sub-pixels 13 in odd-numbered rows to be lit during the light-emitting phase. Meanwhile, the second data line 22 provides a black state data signal, allowing the fourth luminous sub-pixels 14 in even-numbered rows to remain dark during the light-emitting phase. When the fourth scan signal line 34 provides the fourth valid pulse, the first data line 21 provides a black state data signal, enabling the fourth luminous sub-pixels 14 in odd-numbered rows to remain dark during the light-emitting phase, and the second data line 22 provides a lighting data signal, enabling the third luminous sub-pixels 13 in even-numbered rows to be lit during the light-emitting phase. Furthermore, when the first scan signal line 31 provides the first valid pulse, the first data line 21 provides a black state data signal, and the second data line 22 provides a lit state data signal. Conversely, when the second scan signal line 32 provides the second valid pulse, the first data line 21 provides a lit state data signal, and the second data line 22 provides a black state data signal. This ensures that neither the first luminous sub-pixel 11 nor the second luminous sub-pixel 12 is illuminated. Consequently, during the image detection phase, when the third scan signal line 33 provides the third valid pulse, the third luminous sub-pixels 13 in odd-numbered rows are illuminated, and when the fourth scan signal line 34 provides the fourth valid pulse, the third luminous sub-pixels 13 in even-numbered rows are illuminated. Since neither the first luminous sub-pixels 11 nor the second luminous sub-pixels 12 are illuminated during the first scan signal line 31 providing the first valid pulse and the second scan signal line 32 providing the second valid pulse, only the third luminous sub-pixels 13 are illuminated during the image detection phase, and the display panel displays only the second color.

[0062] During the image detection phase, when the fourth luminous sub-pixel 14 is detected, when the third scan signal line 33 provides the third valid pulse, the first data line 21 provides a black state data signal, allowing the third luminous sub-pixels 13 in odd-numbered rows to remain dark during the luminous phase. At this time, the second data line 22 provides a lighting data signal, allowing the fourth luminous sub-pixels 14 in even-numbered rows to be lit during the luminous phase. When the fourth scan signal line 34 provides the fourth valid pulse, the first data line 21 provides a lighting data signal, allowing the fourth luminous sub-pixels 14 in odd-numbered rows to be lit during the luminous phase, and the second data line 22 provides a black state data signal, allowing the third luminous sub-pixels 13 in even-numbered rows to remain dark during the luminous phase. Furthermore, when the first scan signal line 31 provides the first valid pulse, the first data line 21 provides a black state data signal, and the second data line 22 provides a lit state data signal. Conversely, when the second scan signal line 32 provides the second valid pulse, the first data line 21 provides a lit state data signal, and the second data line 22 provides a black state data signal. This ensures that neither the first luminous sub-pixel 11 nor the second luminous sub-pixel 12 is lit. Consequently, during the image detection phase, when the third scan signal line 33 provides the third valid pulse, the fourth luminous sub-pixel 14 in even-numbered rows is lit, and when the fourth scan signal line 34 provides the fourth valid pulse, the fourth luminous sub-pixel 14 in odd-numbered rows is lit. Since neither the first luminous sub-pixel 11 nor the second luminous sub-pixel 12 is lit during the first scan signal line 31 providing the first valid pulse and the second scan signal line 32 providing the second valid pulse, only the fourth luminous sub-pixel 14 is lit during the image detection phase, and the display panel only displays the third color.

[0063] Therefore, during the image detection stage, by adjusting the output signals of the first data line 21 and the second data line 22, only the third light-emitting sub-pixel 13 or the fourth light-emitting sub-pixel 14 can be lit, while other light-emitting sub-pixels remain dark. This results in the entire display panel displaying only the second or third color image. Thus, the lighting status of the third light-emitting sub-pixel 13 or the fourth light-emitting sub-pixel 14 can be detected. Furthermore, since other light-emitting sub-pixels are arranged between adjacent third light-emitting sub-pixels 13 or adjacent fourth light-emitting sub-pixels 14, when a short circuit fault occurs between the first data line 21 and the second data line 22, the judgment can be made directly by observing the display status of the display panel without being affected by interference from other light-emitting sub-pixels.

[0064] In some embodiments, see continue to see Figure 6In a single data frame, the first scan signal line, fourth scan signal line, second scan signal line, and third scan signal line corresponding to adjacent rows of pixels sequentially output valid pulses. In the third time period t21, the first scan signal line provides the first valid pulse; in the fourth time period t22, the fourth scan signal line provides the fourth valid pulse; in the fifth time period t23, the second scan signal line provides the second valid pulse; and in the sixth time period t24, the third scan signal line provides the third valid pulse.

[0065] In some embodiments, during the image detection phase, within the interval where the third scan signal line provides the third valid pulse, the first data line and the second data line output black-state voltage; within the interval where the fourth scan signal line provides the fourth valid pulse, the first data line and the second data line output black-state voltage.

[0066] Specifically, during the image detection phase, when detecting the first or second luminous sub-pixel, the display panel needs to show only the first color image corresponding to the first luminous sub-pixel, or only the first color image corresponding to the second luminous sub-pixel. Therefore, within the interval where the third scan signal line provides the third effective pulse, both the first and second data lines output a black state voltage, keeping the third luminous sub-pixels in odd-numbered rows and the fourth luminous sub-pixels in even-numbered rows connected to the third scan signal line in a dark state. Within the interval where the fourth scan signal line provides the fourth effective pulse, both the first and second data lines still need to output a black state voltage, keeping the third luminous sub-pixels in even-numbered rows and the fourth luminous sub-pixels in odd-numbered rows connected to the fourth scan signal line in a dark state.

[0067] During image detection of the first luminous sub-pixel, within a single data frame, during the interval where the first scan signal line provides the first valid pulse, the first data line outputs a lit data signal, and the second data line outputs a black state data signal; at this time, only the first luminous sub-pixel is lit. During the interval where the second scan signal line provides the second valid pulse, the first data line continues to output a lit data signal, and the second data line outputs a black state data signal; at this time, all luminous sub-pixels are not lit. During the interval where the third scan signal line provides the third valid pulse, both the first and second data lines output a black state voltage; at this time, all luminous sub-pixels are not lit. During the interval where the fourth scan signal line provides the fourth valid pulse, both the first and second data lines output a black state voltage; at this time, all luminous sub-pixels are not lit. This ensures that within a single data frame, only during the interval of the first valid pulse, the first luminous sub-pixel is lit. Therefore, during the entire image detection phase, the display panel can only display the first color image corresponding to the first luminous sub-pixel.

[0068] During image detection of the second luminous sub-pixel, within a single data frame, during the interval where the first scan signal line provides the first valid pulse, the first data line outputs a black state data signal, and the second data line outputs a lit data signal; at this time, all luminous sub-pixels are not emitting light. During the interval where the second scan signal line provides the second valid pulse, the first data line continues to output a black state data signal, and the second data line outputs a lit data signal; at this time, only the second luminous sub-pixel is lit. During the interval where the third scan signal line provides the third valid pulse, both the first and second data lines output a black state voltage; at this time, all luminous sub-pixels are not emitting light. During the interval where the fourth scan signal line provides the fourth valid pulse, both the first and second data lines output a black state voltage; at this time, all luminous sub-pixels are not emitting light. Therefore, within a single data frame, only during the interval of the second valid pulse is the second luminous sub-pixel lit. Thus, during the entire image detection phase, the display panel can only display the first color image corresponding to the second luminous sub-pixel.

[0069] In some embodiments, Figure 7 This illustration shows another structural diagram of a display panel provided in one embodiment of the present application, such as... Figure 7 As shown, the display panel also includes multiple multiplexing modules 40. The input terminal 41 of each multiplexing module 40 is connected to the data signal terminal 51 of the driver chip 50. The first output terminal 42 of each multiplexing module 40 is connected to the first data line 21, and the second output terminal 43 of each multiplexing module 40 is connected to the second data line 22. The multiplexing module 40 is used to provide a data signal to the first data line 21 within the interval where the first scan signal line 31 provides a first valid pulse, and to provide a data signal to the second data line 22 within the interval where the second scan signal line 32 provides a second valid pulse.

[0070] Specifically, during the image detection stage, the data signal terminal 51 of the driver chip 50 inputs a signal to the input terminal 41 of the multiplexing module 40, causing the multiplexing module 40 to start working.

[0071] When detecting the image of the first light-emitting sub-pixel 11, the multiplexing module 40 provides a lighting data signal to the first data line 21 through the first output terminal 42 during the period when the first scan signal line 31 provides the first valid pulse. During the period when the second scan signal line 32 provides the second valid pulse, it continues to provide a black state data signal to the second data line 22 through the second output terminal 43. This ensures that during the period when the first scan signal line 31 provides the first valid pulse, the first data line 21 provides the lighting data signal, enabling the first light-emitting sub-pixel 11 to light up during the light-emitting phase, while the second light-emitting sub-pixel 12 does not receive the black state data signal because the second scan signal line 32 does not output a valid pulse. During the period when the second scan signal line 32 provides the second valid pulse, the second light-emitting sub-pixel 12 does not light up because the second data line 22 provides a black state data signal, while the first light-emitting sub-pixel 11 does not receive the black state data signal because the first scan signal line 31 does not output a valid pulse. Therefore, during the period when detecting the lighting status of the first light-emitting sub-pixel 11 in the display panel, only the first light-emitting sub-pixel 11 is lit.

[0072] When detecting the second light-emitting sub-pixel 12, the multiplexing module 40 provides a black-state data signal to the first data line 21 through the first output terminal 42 during the period when the first scan signal line 31 provides the first valid pulse. During the period when the second scan signal line 32 provides the second valid pulse, it provides a lighting data signal to the second data line 22 through the second output terminal 43. This ensures that during the period when the first scan signal line 31 provides the first valid pulse, the first light-emitting sub-pixel 11 will not light up because the first data line 21 provides the black-state data signal, and the second light-emitting sub-pixel 12 will not receive the black-state data signal because the second scan signal line 32 does not output a valid pulse. During the period when the second scan signal line 32 provides the second valid pulse, the first light-emitting sub-pixel 11 will not receive the lighting data signal because the first scan signal line 31 does not output a valid pulse, and the second light-emitting sub-pixel 12 can light up during the light-emitting phase because the second data line 22 provides the lighting data signal. Therefore, during the period when detecting the lighting status of the second light-emitting sub-pixel 12 in the display panel, only the second light-emitting sub-pixel 12 is lit.
