[0003] In related technologies, the grooved area is prone to display problems, which greatly reduces the display effect of the display panel. Summary of the Invention

[0005] According to one aspect of the present invention, a driving method for a display panel is provided. The display panel has a display area and a light-transmitting area. The display panel includes data lines and a plurality of pixel circuits arranged in an array. Each column of the pixel circuits is connected to a data line. The number of pixel circuits connected to the data lines corresponding to the light-transmitting area is less than the number of pixel circuits connected to the data lines corresponding to the display area. The pixel circuits are located in the display area. The driving method includes: Within one display cycle, a preset data voltage is transmitted to at least a portion of the data lines corresponding to at least a portion of the row scan cycles within the light-transmitting area; Wherein, at least some of the rows include the last row of pixels corresponding to the light-transmitting area, and the preset data voltage is a non-black state voltage.

[0006] Optionally, the driving method further includes: Obtain the parameters of the light-transmitting area; the parameters of the light-transmitting area include the size of the light-transmitting area; The size of the data loading area corresponding to the data line transmitting the preset data voltage is determined based on the parameters of the light-transmitting area.

[0007] Optionally, the data loading area includes at least a portion of the coordinates of the row containing the last row of pixel circuits corresponding to the light-transmitting area.

[0008] Optionally, the shape of the data loading area includes one of a semicircle, a triangle, or a trapezoid.

[0009] Optionally, before transmitting the preset data voltage to the data line, the driving method further includes: Adjust the proportion of data within the coverage area of ​​the data loading area according to the target data voltage of the display area; Preferably, within a display cycle, transmitting a preset data voltage to at least a portion of the data lines corresponding to at least a portion of the row scan cycles within the light-transmitting area includes: Within a display cycle, the preset data voltage is transmitted to the data line corresponding to the light-transmitting area according to the data ratio in the data loading area.

[0010] Optionally, adjusting the data ratio within the coverage area of ​​the data loading area according to the target data voltage of the display area includes: A data lookup table is established based on the target data voltage in the display area; Based on the data lookup table, determine the proportion of data within the coverage area of ​​the data loading area; The data ratio satisfies the linear change of the gamma curve, and the data lookup table is used to characterize the mapping relationship between the data ratio of the preset data voltage and the grayscale of the display area.

[0011] Optionally, within a display cycle, for the pixel circuits in the same row, a multi-pulse timing sequence is used to write actual data voltages to the pixel circuits corresponding to the display area in segments, and to transmit the preset data voltages to the data lines corresponding to the light-transmitting area; Preferably, the multi-pulse timing includes a 3-pulse timing.

[0012] Optionally, the difference between the preset data voltage transmitted on the data line connected to the last row of pixel circuits corresponding to the light-transmitting area and the actual data voltage transmitted on the data line connected to the adjacent row of pixel circuits corresponding to the display area is less than the preset value. Preferably, the preset data voltage is the same as the data voltage transmitted within the display area.

[0013] According to another aspect of the present invention, a display panel is provided, the display panel having a display area and a light-transmitting area, the display panel comprising: Multiple pixel circuits arranged in an array, the pixel circuits being located in the display area; The data line connects one data line to each column of pixel circuits, and the number of pixel circuits connected to the data line corresponding to the light-transmitting area is less than the number of pixel circuits connected to the data line corresponding to the display area. A driver is configured to transmit a preset data voltage to at least a portion of the data lines corresponding to at least a portion of the row scan cycles within the light-transmitting area during a display cycle; Wherein, at least some of the rows include the last row of pixels corresponding to the light-transmitting area, and the preset data voltage is a non-black state voltage.

[0014] Optionally, the pixel circuit includes a driving transistor and a data writing transistor, wherein the data writing transistor is used to transmit data voltage on the data line in segments to the driving transistor in response to a multi-pulse timing sequence.

[0015] The technical solution provided in this embodiment transmits a preset data voltage (non-black state voltage) to at least a portion of the column data lines corresponding to at least a portion of the row scan cycles within the light-transmitting area, including its last row. This reduces the loading between the data lines corresponding to the light-transmitting area and the data lines corresponding to the display area within the light-transmitting area's scan cycle, thereby improving the load difference of the same data line in the light-transmitting area and the display area. This reduces the magnitude difference of the data voltage transmitted within three pulse windows, thus improving the problem of inconsistent data voltage written three times in each row of pixel rows at the boundary between the light-transmitting area and the display area. Under long-term operation, this helps to improve the stress on the driving transistors and effectively solves the problem of upward-extending bright lines at the boundary between the light-transmitting area and the display area, further improving the display effect.

Detailed Implementation

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0020] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0021] Figure 1 This is a schematic diagram of the structure of a display panel provided in an embodiment of the present invention, with reference to... Figure 1 The display panel has a display area AA and a non-display area NAA surrounding the display area AA. The display panel includes data lines DL and multiple pixel circuits (not shown in the figure) arranged in an array. The pixel circuits are located in the display area AA, which is used to display the image. The non-display area NAA can be used to set the peripheral circuits driving the pixel circuits. The display panel also has a light-transmitting area GA, which is a notch design and can be used to house a camera. No pixel circuits are set in the light-transmitting area GA. Pixel circuits in the same column are connected to the same data line DL. The number of pixel circuits connected to the data line DL corresponding to the light-transmitting area GA is less than the number of pixel circuits connected to the data line DL corresponding to the display area AA. Multiple data lines DL extend along a second direction Y and are arranged along a first direction X, where the first direction X can be a row direction and the second direction Y can be a column direction.

[0022] Figure 2This is a schematic diagram of a pixel circuit driving timing provided in an embodiment of the present invention. The pixel circuit includes a driving transistor and a data writing transistor. A first scan signal S1 is used to control the on and off states of the data writing transistor. The data writing transistor transmits data voltage to the gate of the driving transistor, which generates a driving current to drive the light-emitting element to emit light. During display, the light-transmitting area GA is in a black state, and the display area AA is in a bright state. Since there is no pixel circuit within the light-transmitting area GA, a loading abrupt change occurs at the lower edge of the light-transmitting area GA and the boundary of the display area, resulting in a bright line at the lower edge of the light-transmitting area GA. Here, loading refers to the equivalent driving load of the data line DL during the scan cycle.

[0023] Here, the first scan signal S1 is a 3-pulse signal. Under the 3-pulse drive, the data voltage Vdata of the same row of pixel circuits is not written all at once, but is written in 3 consecutive scan cycles (corresponding to the scan timing of the first few rows). The light-transmitting area GA is a black screen (corresponding to the second level V2 of the data voltage Vdata), and the display area AA is a white screen (corresponding to the first level V1 of the data voltage Vdata). Along the scan direction (column direction), in the first few rows of pixels below the black-to-white boundary, during the 3-pulse writing process, the first 2 pulses correspond to the data voltage (V2) of the black screen displayed by the pixels in the rows above the black-to-white boundary. Only the last pulse can write the data voltage (V1) of the white screen. The 3 pulses corresponding to the pixels in each subsequent row all write the data voltage of the white screen. This results in a difference in the data voltage finally written to the pixels in the black-to-white boundary row compared to other rows. Consequently, the stress of the driving transistors corresponding to the black-to-white boundary row differs from that of other rows, and the stress effect spreads to adjacent rows. As time increases, an upward-extending bright line is eventually generated at the black-to-white boundary position.

[0024] Combination Figure 2 Taking a pulse width of 4 lines as an example, at the boundary between the lower edge of the light-transmitting area GA and the display area AA (i.e., the black-to-white boundary line), the first scan signal S1-H1 of the first row of pixels corresponding to the black-to-white transition of the display image has its first two pulses corresponding to the data voltage for displaying the black image, and its third pulse corresponding to the data voltage for displaying the white image; the first scan signal S1-H9 of the ninth pixel circuit corresponding to the black-to-white transition of the display image has all three pulses corresponding to the data voltage for displaying the white image. In other words, the data voltage written to the first eight rows of pixels at the black-to-white boundary position is different from the data voltage written to other rows, and the driving transistors corresponding to these first eight rows of pixels experience different stresses, thus producing a murmur.

[0025] To address the above problems, embodiments of the present invention provide a driving method for a display panel. Figure 3A flowchart of a display panel driving method provided in an embodiment of the present invention is shown below. Figure 3 The driving method provided in this embodiment includes: S110. Within a display cycle, a preset data voltage is transmitted to at least a portion of the column data lines corresponding to at least a portion of the row scan cycles within the light-transmitting area.

[0026] Among them, at least some rows include the last row of pixels corresponding to the light-transmitting area, and the preset data voltage is the non-black state voltage.

[0027] The technical solution provided in this embodiment transmits a preset data voltage (non-black state voltage) to at least a portion of the column data lines corresponding to at least a portion of the row scan cycles within the light-transmitting area, including its last row. This reduces the loading between the data line DL corresponding to the light-transmitting area GA and the data line DL corresponding to the display area AA within the scan cycle of the light-transmitting area GA. This improves the load difference of the same data line DL in the light-transmitting area GA and the display area AA, thereby reducing the magnitude difference of the data voltage transmitted within three pulse windows. This improves the problem of inconsistent data voltage written three times in each row of the pixel row at the boundary between the light-transmitting area GA and the display area AA. Under long-term operation, this helps to improve the stress on the driving transistor and effectively solves the problem of upward-extending bright lines at the boundary between the light-transmitting area GA and the display area AA, which is beneficial to further improving the display effect.

[0028] Figure 4 A flowchart of another display panel driving method provided in an embodiment of the present invention is shown below. Figure 4 Based on the above embodiments, optionally, the driving method for the display panel includes: S210. Obtain the parameters of the light-transmitting area; the parameters of the light-transmitting area include the size of the light-transmitting area.

[0029] The dimensions of the light-transmitting area GA can include its width, height, and other dimensions.

[0030] Optionally, the parameters of the light-transmitting area GA may also include the number of data lines covered between the left and right boundaries of the light-transmitting area GA, and the number of scan lines covered between the upper and lower boundaries.

[0031] S220. Determine the size of the data loading area corresponding to the data line transmission preset data voltage based on the parameters of the light-transmitting area.

[0032] S110. Within a display cycle, a preset data voltage is transmitted to at least a portion of the column data lines corresponding to at least a portion of the row scan cycles within the light-transmitting area.

[0033] Here, the corresponding data loading area can be determined by the driver chip using an algorithm based on the relevant parameters obtained above. The data loading area is used to determine the range of regions within the light-transmitting area (GA) where the data voltage is loaded. Based on the parameters of the light-transmitting area (GA), the data loading area can perfectly fit the physical boundary of the light-transmitting area (GA), thereby matching the cutout width of the light-transmitting area (GA) and avoiding affecting the light-emitting effect of the normal display area (AA).

[0034] In a preferred embodiment, the area divided by the data loading area can completely cover the multi-pulse drive timing (e.g., 3-pulse drive timing) of the display panel, so as to reduce the difference in data voltage transmitted in multiple pulse windows during scanning.

[0035] Optionally, in this embodiment, the data loading area includes at least some of the coordinate points of the row where the last row of pixel circuits corresponding to the light-transmitting area GA is located, so as to ensure that there will be no voltage change at the boundary between the light-transmitting area GA and the display area AA, thereby solving the problem of abnormal boundary display.

[0036] Figure 5 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention, specifically... Figure 1 The diagram shown is a partial enlarged view of the display panel. (Refer to...) Figure 5 In this embodiment, the data loading area forms a closed shape (as shown in the green semicircle in the figure). This closed shape fits the lower edge of the light-transmitting area GA to achieve a smooth transition of source loading from the light-transmitting area GA to the display area AA. This allows the data line DL at the junction of the light-transmitting area GA and the display area AA to be covered by a preset data voltage, thereby eliminating the loading abrupt change at the junction.

[0037] Optionally, the shape of the data loading area may include one of the following: a semicircle, a triangle, or a trapezoid.

[0038] Taking a semi-circular data loading area as an example, the radius of the semi-circular data loading area is determined by the driver chip. For example, a suitable radius can be selected by establishing a radius lookup table of Lut_R[0~7] to match different GA hole widths and ensure the best coverage of the GA.

[0039] In one optional implementation of this embodiment, within a display cycle, for the same row of pixel circuits, a target data voltage is written segmentally to the pixel circuit corresponding to the display area AA using a 3-pulse timing sequence, and a preset data voltage is transmitted to the data line corresponding to the light-transmitting area GA. The radius of the semi-circular data loading area is greater than or equal to the number of scan rows of 3 pulses, so as to completely cover the writing window of 3 pulses and ensure that the difference between the 3 written data voltages is small. During the scanning process, when the driver chip triggers the corresponding row, it transmits the preset data voltage to the data line DL within the coverage area of ​​the semi-circular data loading area. The data lines DL outside the coverage area of ​​the semi-circular data loading area may transmit a black state voltage or not transmit a voltage.

[0040] In this embodiment, the number of data lines DL covered in each row within the semi-circular data loading area changes continuously and smoothly (the closer the scan row is to the top of the light-transmitting area GA, the fewer the number of data lines covered by the semi-circular data loading area and the fewer the data lines to which the preset data voltage is applied; the closer the scan row is to the bottom of the light-transmitting area GA, the more the number of data lines covered by the semi-circular data loading area and the more the data lines to which the preset data voltage is applied), so as not to generate new loading abrupt changes on the left and right sides, avoid new crosstalk, and help improve the display effect.

[0041] It should be understood that the data loading area enclosed by the closed graphic described in the above embodiments is not a real physical pattern existing inside the light-transmitting area GA, but a virtual graphic formed by multiple data points.

[0042] In this embodiment, the difference between the preset data voltage transmitted on the data line connected to the last row of pixel circuits corresponding to the light-transmitting area and the actual data voltage transmitted on the data line connected to the adjacent row of pixel circuits corresponding to the display area is less than the preset value. That is, the preset data voltage is close to or the same as the data voltage transmitted in the normal display area AA, so that the driving chip applies the same driving load to the data line DL as to the display area AA during the scanning cycle of the light-transmitting area GA, making the equivalent source loading of the corresponding data line DL in the light-transmitting area GA and the display area AA the same, thereby eliminating the load difference of the data line DL in the light-transmitting area GA and the display area AA.

[0043] This solution requires no additional pixel circuitry and does not alter the hardware layout of the display panel. By determining the data loading area that needs to transmit voltage to the light-transmitting area GA based on its parameters, and transmitting a preset data voltage to the corresponding data line DL according to the corresponding data loading area during the scanning process of the light-transmitting area GA, it eliminates abrupt changes in source loading between the light-transmitting area GA and the display area AA. This improves the voltage write consistency problem under multi-drive timing and eliminates the stress difference of the driving transistors corresponding to the boundary row between the light-transmitting area GA and the display area AA, thereby improving the display effect.

[0044] Optionally, the preset data voltage is the same as the data voltage transmitted within the display area.

[0045] Figure 6 A flowchart of another display panel driving method provided in an embodiment of the present invention is shown below. Figure 6 Based on the above embodiments, optionally, the display panel driving method provided in this embodiment includes: S210. Obtain the parameters of the light-transmitting area; the parameters of the light-transmitting area include the size of the light-transmitting area.

[0046] S220. Determine the size of the data loading area corresponding to the data line transmission preset data voltage based on the parameters of the light-transmitting area.

[0047] S310. Adjust the data ratio within the data loading area coverage according to the target data voltage of the display area.

[0048] Among them, a data lookup table that represents the mapping relationship between the data ratio of the preset data voltage and the grayscale of the display area can be used to determine the data ratio within the coverage area of ​​the data loading area.

[0049] Specifically, step S310 includes: Establish a data lookup table based on the target data voltage in the display area; By combining the data lookup table, determine the proportion of data within the coverage area of ​​the data loading zone.

[0050] Specifically, a data lookup table is established by allocating different data ratios based on the data voltage of display area AA. The value of the data lookup table register is adjusted according to the actual situation to conform to gamma linear interpolation and ensure that the preset data voltage meets the gamma curve variation. In the data lookup table, each gray level (or gray level range) corresponds to a data ratio.

[0051] During the display process, the system reads the data voltage corresponding to the current screen of the display area AA, matches the corresponding data ratio from the lookup table, and dynamically adjusts the loading ratio of the preset data voltage in the light-transmitting area GA. Ultimately, it can ensure the transition effect of source loading between the light-transmitting area GA and the display area AA under different display screens, thereby eliminating abnormal display lines in the entire grayscale range and ensuring the display effect under different display screens.

[0052] For example, the data lookup table can include multiple gray levels, namely 0 gray level, 32 gray level, 64 gray level, 96 gray level, 128 gray level, 160 gray level, 192 gray level, 224 gray level, and 255 gray level. Each gray level corresponds to a data ratio. For example, the data ratio corresponding to 0 gray level is 0, 32 gray level is 13, 64 gray level is 56, 96 gray level is 132, 128 gray level is 241, 160 gray level is 385, 192 gray level is 564, 224 gray level is 780, and 255 gray level is 1024. The data ratio increases linearly with the gray level, conforming to the linear change of the gamma curve. All values ​​are burned into the lookup table register of the driver chip, which can support fine-tuning to adapt to individual differences between different display panels.

[0053] During the display process, the data ratio within the data loading area is determined using a lookup table based on the target data voltage index of display area AA. If the target data voltage of display area AA falls within a specified range, the corresponding data ratio can be calculated using gamma linear interpolation, thus preventing sudden changes in the data ratio from affecting the display effect.

[0054] S1101. Within a display cycle, a preset data voltage is transmitted to the data line corresponding to the light-transmitting area according to the data ratio in the data loading area.

[0055] After determining the data ratio within the data loading area, a preset data voltage is transmitted to the corresponding data line DL within the light-transmitting area GA according to the scanning cycle.

[0056] Experimental verification shows that after adopting the technical solution provided in this embodiment, the optimization yield of abnormal display lines at the lower edge of the light-transmitting area GA reaches 100%, and the minimum noticeable difference (JND) is within 2.2, which greatly improves the display effect and conforms to the test results of human visual perception.

[0057] Optionally, embodiments of the present invention also provide a display panel, such as... Figure 1 As shown, the display panel has a display area AA and a light-transmitting area GA, and the display panel includes: Multiple pixel circuits are arranged in an array, and the pixel circuits are located in the display area AA; Data line DL, one data line DL is connected to each column of pixel circuits. The number of pixel circuits connected to the data line DL corresponding to the light-transmitting area GA is less than the number of pixel circuits connected to the data line DL corresponding to the display area AA. A driver is used to transmit a preset data voltage to at least a portion of the column data lines DL corresponding to at least a portion of the row scan cycles within the light-transmitting area GA during a display cycle; Among them, at least some rows include the last row of pixels corresponding to the light-transmitting area GA, and the preset data voltage is the non-black state voltage.

[0058] Optionally, in this embodiment, the pixel circuit includes a driving transistor and a data writing transistor, wherein the data writing transistor is used to transmit the data voltage on the data line DL in segments to the driving transistor in response to a multi-pulse timing sequence (e.g., a 3-pulse timing sequence).

[0059] The technical solution provided in this embodiment transmits a preset data voltage (non-black state voltage) to at least a portion of the column data lines corresponding to at least a portion of the row scan cycles within the light-transmitting area, including its last row. This reduces the loading between the data line DL corresponding to the light-transmitting area GA and the data line DL corresponding to the display area AA within the scan cycle of the light-transmitting area GA. This improves the load difference of the same data line DL in the light-transmitting area GA and the display area AA, thereby reducing the magnitude difference of the data voltage transmitted within three pulse windows. This improves the problem of inconsistent data voltage written three times in each row of the pixel row at the boundary between the light-transmitting area GA and the display area AA. Under long-term operation, this helps to improve the stress on the driving transistor and effectively solves the problem of upward-extending bright lines at the boundary between the light-transmitting area GA and the display area AA, which is beneficial to further improving the display effect.

[0060] It should be understood that the various forms of processes shown above can be used, with steps reordered, added, or deleted. For example, the steps described in this invention can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution of this invention can be achieved, and this is not limited herein.

[0061] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
