[0024] In some embodiments, the first data signal line and the second data signal line are arranged alternately within the display area.

[0025] In some embodiments, the number of first data signal lines and the number of second data signal lines are the same.

[0026] In a second aspect, embodiments of this application provide a Gamma adjustment method for performing Gamma adjustment on a display device of the first aspect. The display device includes a plurality of light-emitting pixels arranged in an array, the plurality of light-emitting pixels including a first light-emitting pixel and a second light-emitting pixel, a first data signal line electrically connected to the first light-emitting pixel, and a second data signal line electrically connected to the second light-emitting pixel. The method includes:

The first data signal line can be connected to the first side of the non-display area, and the second data signal line can be connected to the second side of the non-display area. Under the influence of resistance and capacitance, the greater the distance between the data signal line and the data signal terminal, the greater the voltage attenuation. Therefore, in the display area near the first side of the non-display area, the brightness of the first light-emitting pixel is higher and the brightness of the second light-emitting pixel is lower; in the display area near the second side of the non-display area, the brightness of the second light-emitting pixel is higher and the brightness of the first light-emitting pixel is lower. For different display areas, the brightness offset of the first light-emitting pixel and the second light-emitting pixel can be mutually neutralized or mutually compensated, thereby reducing the difference in light emission brightness between various display areas and improving the phenomenon of uneven display brightness caused by the different light emission brightness of light-emitting devices at different positions.

Detailed Implementation

[0049] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples of this application.

[0050] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0051] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The embodiments will now be described in detail with reference to the accompanying drawings.

[0052] With the continuous development of display device technology, OLED (Organic Light-Emitting Diode) devices and other light-emitting devices have been gradually applied to various display device products such as mobile phones, tablets, and laptops.

[0053] In one embodiment of the panel product, taking AMOLED (Active-matrix organic light-emitting diode) as an example, the display module's screen includes not only OLED devices but also GOA scanning units that provide scanning signals, TFT (Thin Film Transistor) pixel circuits, and signal traces between various devices and circuits. Resistance and capacitance are formed between these devices and signal traces. When driving the OLED devices to emit light, the driving current will generate a voltage drop IRDrop due to the influence of the resistance and capacitance within the screen. Because the trace lengths between the light-emitting devices and the driving chip differ at different locations, the resulting IRDrop is also different. Therefore, the brightness of the light-emitting devices farther from the driving chip differs from that of the light-emitting devices closer to the driving chip, resulting in uneven display brightness in the display device.

[0054] To address the aforementioned technical problems, embodiments of this application provide a display device, a Gamma tuning method, and a driving method for the display device. The display device provided in the embodiments of this application will be described first.

[0055] Figure 1A schematic diagram of a display device according to an embodiment of this application is shown. The display device has a display area 1 and a non-display area 2. The display device includes multiple data signal lines arranged along a first direction X within the display area 1. The display area 1 of the display device also includes multiple light-emitting pixels arranged in an array, including a first light-emitting pixel 11 and a second light-emitting pixel 12.

[0056] Multiple data signal lines include a first data signal line Data1 and a second data signal line Data2. The first data signal line Data1 extends within the display area 1 along the second direction Y and extends to the first side of the non-display area 2. A first data signal on the first data signal line Data1 is input from the first side. The second data signal line Data2 extends within the display area 1 along the second direction Y and extends to the second side of the non-display area 2. A second data signal on the second data signal line Data2 is input from the second side. The non-display area 2 at least partially surrounds the display area 1, and the first and second sides of the non-display area 2 are located on opposite sides of the display area 1. The first direction X and the second direction Y intersect, and there is a certain angle between the first direction X and the second direction Y.

[0057] The first data signal line Data1 can extend within the display area 1 and be electrically connected to the first light-emitting pixel 11; the second data signal line Data2 can extend within the display area 1 and be electrically connected to the second light-emitting pixel 12.

[0058] Since the first data signal line Data1 starts from the first side of the non-display area 2 and extends along the second direction Y within the display area 1, as the first data signal line Data1 transmits the corresponding data signal, the corresponding impedance and capacitive reactance will continuously increase with the extension of the first data signal line Data1. That is, the position away from the first side of the non-display area 2 will generate a larger voltage drop under the influence of resistance and capacitance, thereby causing the signal voltage of the data signal received by the first light-emitting pixel 11 on the first side away from the non-display area 2 to be attenuated, thus affecting the brightness of the first light-emitting pixel 11. For example, for two first light-emitting pixels 11, under the same data signal, the voltage attenuation of the data signal received by the first light-emitting pixel 11 closer to the first side of the non-display area 2 is smaller, while the voltage attenuation of the data signal received by the first light-emitting pixel 11 on the first side away from the non-display area 2 is larger, which will result in the brightness of the first light-emitting pixel 11 on the first side away from the non-display area 2 being lower than that of the first light-emitting pixel 11 on the first side closer to the first side of the non-display area 2.

[0059] Similarly, since the second data signal line Data2 starts from the second side of the non-display area 2 and extends along the second direction Y within the display area 1, the luminous brightness of the second luminous pixel 12, which is farther from the second side of the non-display area 2, is lower than that of the second luminous pixel 12, which is closer to the second side of the non-display area 2, under the same data signal.

[0060] When multiple first data signal lines Data1 and multiple second data signal lines Data2 are arranged along the first direction X within the display area 1, the brightness of the first light-emitting pixel 11 closer to the first side of the non-display area 2 is higher, and the brightness of the second light-emitting pixel 12 closer to the first side of the non-display area 2 is lower. Similarly, the brightness of the first light-emitting pixel 11 closer to the second side of the non-display area 2 is lower, and the brightness of the second light-emitting pixel 12 closer to the second side of the non-display area 2 is higher.

[0061] If all data signal lines in display area 1 are the first data signal line Data1, then under the same data signal drive, the brightness of the first light-emitting pixel 11 in the display area near the first side of the non-display area 2 will be higher, while the brightness of the first light-emitting pixel 11 in the display area near the first side of the non-display area 2 will be lower, resulting in uneven display brightness. Similarly, if all data signal lines in display area 1 are the second data signal line Data2, uneven display brightness will also occur.

[0062] By configuring the data signal lines in display area 1 to consist of a first data signal line (Data1) and a second data line, in the portion of display area 1 near the first side of non-display area 2, when the brightness of the first light-emitting pixel 11 is too high, the brightness is neutralized by the lower brightness of the second light-emitting pixel 12 in that portion of the display area, preventing the brightness of the portion of display area near the first side of non-display area 2 from being too high relative to other display areas. Similarly, for the portion of display area 1 near the second side of non-display area 2, when the brightness of the second light-emitting pixel 12 is too high, the brightness is neutralized by the lower brightness of the first light-emitting pixel 11 in that portion of the display area, also preventing the brightness of the portion of display area near the second side of non-display area 2 from being too high relative to other display areas. The symmetrical arrangement of the first light-emitting pixel 11 and the second light-emitting pixel 12 on both sides of display area 1 reduces the difference in brightness between different display areas, thereby improving the unevenness of display brightness.

[0063] As an optional implementation, if each data signal line in display area 1 is connected to the light-emitting pixels in the same way, for example, a first data signal line Data1 is electrically connected to the first light-emitting pixel 11 in the same column, and a second data signal line Data2 is electrically connected to the second light-emitting pixel 12 in the same column, then the ratio of the number of first data signal lines Data1 to the number of second signal lines can be approximately considered the same as the ratio of the number of first light-emitting pixels 11 to the number of second light-emitting pixels 12. When the number of first data signal lines Data1 is greater than the number of second data signal lines Data2, in the part of the display area near the first side of the non-display area 2, the number of first light-emitting pixels 11 will be higher than the number of second light-emitting pixels 12. At this time, the brightness of the first light-emitting pixels 11 is higher, and the brightness of the second light-emitting pixels 12 is lower. Even when the number of first light-emitting pixels 11 is significantly greater than the number of second light-emitting pixels 12, the brightness of this part of the display area will still be higher. Therefore, in order to improve the uneven brightness between different display areas in display area 1, the number of the first data signal line Data1 and the number of the second data signal line Data2 in display area 1 can be kept consistent or close. For example, the difference between the number of the first data signal line Data1 and the number of the second data signal line Data2 should be less than the preset line difference threshold, so as to avoid a large difference in the number of the first light-emitting pixel 11 and the second light-emitting pixel 12, which would lead to uneven display brightness.

[0064] In this embodiment, by providing a first data signal line Data1 and a second data signal line Data2 arranged along the first direction X within the display area 1, the first data signal line Data1 can be electrically connected to the first light-emitting pixel 11, and the second data signal line Data2 can be electrically connected to the second light-emitting pixel 12. The first data signal line Data1 can be connected to the first side of the non-display area 2, and the second data signal line Data2 can be connected to the second side of the non-display area 2. Due to the influence of resistance and capacitance, the greater the distance between the data signal line and the data signal terminal, the greater the voltage attenuation. Consequently, in the display area near the first side of the non-display area 2, the brightness of the first light-emitting pixel 11 is higher, and the brightness of the second light-emitting pixel 12 is lower; conversely, in the display area near the second side of the non-display area 2, the brightness of the second light-emitting pixel 12 is higher, and the brightness of the first light-emitting pixel 11 is lower. For different display areas, the brightness offsets of the first light-emitting pixel 11 and the second light-emitting pixel 12 can be mutually neutralized or compensated, thereby reducing the difference in brightness between different display areas and improving the phenomenon of uneven display brightness caused by the different brightness of light-emitting devices at different positions.

[0065] Please refer to Figure 2 In some embodiments, the display device may include a driver chip DDIC and multiple data signal fan-out lines.

[0066] The driver chip DDIC includes multiple data signal terminals. The first end of the data signal fan-out line is electrically connected to the corresponding data signal terminal, and the second end of the data signal fan-out line is electrically connected to the data signal line.

[0067] The data signal fan-out line can be connected to the corresponding data signal terminal of the driver chip DDIC. The driver chip DDIC can output different data signals through different data signal terminals, and output them to each data signal line in display area 1 through the data signal fan-out line to drive the light-emitting pixels in display area 1 to display images.

[0068] It is understandable that the number of data signal terminals of the driver chip DDIC can correspond to the number of data signal fan-out lines, but the number of data signal fan-out lines may not be the same as the number of data signal lines. For example, the non-display area 2 of the display device can be equipped with a multiplexing module. A single multiplexing module can be electrically connected to one data signal fan-out line and at least two data signal lines, thereby realizing time-division multiplexing of data signals.

[0069] It should be understood that when a display device includes a multiplexing module or other modules that implement time-division multiplexing of data signals, the multiple data signal lines connected to the same multiplexing module or similar modules should be data signal lines of the same type, for example, they can all be the first data signal line Data1, or they can all be the second data signal line Data2.

[0070] Please continue to refer to Figure 2 In some embodiments, the aforementioned data signal fan-out line may include a first data signal fan-out line Fan1 and a second data signal fan-out line Fan2.

[0071] One end of the first data signal fan-out line Fan1 is electrically connected to the driver chip DDIC, and the other end can extend to the first side of the non-display area 2 and be electrically connected to the first data signal line Data1.

[0072] One end of the second data signal fan-out line Fan2 is electrically connected to the driver chip DDIC, and the other end can extend to the second side of the non-display area 2 and be electrically connected to the second data signal line Data2.

[0073] As an optional implementation, the first side of the non-display area 2 and the second side of the non-display area 2 are disposed opposite to the display area 1.

[0074] The first data signal fan-out line Fan1 extends to the first side of the non-display area 2 and is electrically connected to the first data signal line Data1. At this time, among the first light-emitting pixels 11 in the same column that are electrically connected to the first data signal line Data1, the voltage drop generated by the first light-emitting pixel 11 closer to the first side of the non-display area 2 is smaller, and the voltage drop generated by the first light-emitting pixel 11 farther from the first side of the non-display area 2 is larger.

[0075] Correspondingly, the second data signal fan-out line Fan2 extends to the second side of the non-display area 2 and is connected to the second data signal line Data2. At this time, among the second light-emitting pixels 12 in the same column that are electrically connected to the second data signal line Data2, the voltage drop generated by the second light-emitting pixel 12 closer to the second side of the non-display area 2 is smaller, and the voltage drop generated by the second light-emitting pixel 12 farther from the second side of the non-display area 2 is larger.

[0076] Considering the first luminous pixel 11 and the second luminous pixel 12 described above, since the first side and the second side of the non-display area 2 are positioned opposite the display area 1, the first side closer to the non-display area 2 is equivalent to the second side farther away from the non-display area 2. Therefore, the voltage drop generated by the first luminous pixel 11 closer to the first side of the non-display area 2 is smaller, while the voltage drop generated by the second luminous pixel 12 is larger. Conversely, the voltage drop generated by the first luminous pixel 11 closer to the second side of the non-display area 2 is larger, while the voltage drop generated by the second luminous pixel 12 is smaller. Both ends of the display area 1 contain luminous pixels with larger voltage drops and luminous pixels with smaller voltage drops, thereby preventing the voltage drop of all luminous pixels at one end of the display area 1 from being too high or too low, and improving the phenomenon of uneven display brightness.

[0077] It should be noted that the driver chip DDIC is usually located in the bonding area of ​​the non-display area 2 of the display device, and this bonding area can be located on the first side or the second side of the non-display area 2.

[0078] If the bonding area is located on the first side of the non-display area 2, the first data signal fan-out line Fan1, also located on the first side of the non-display area 2, can be directly electrically connected to the driver chip DDIC. However, the second data signal fan-out line Fan2, located on the second side of the non-display area 2, needs to be electrically connected to the driver chip DDIC via a connection trace. Conversely, if the bonding area is located on the second side of the non-display area 2, the second data signal fan-out line Fan2 can be directly electrically connected to the driver chip DDIC, while the first data signal fan-out line Fan1, located on the first side of the non-display area 2, needs to be electrically connected to the driver chip DDIC via a connection trace.

[0079] Understandably, a single first data signal fan-out line Fan1 can be electrically connected to one first data signal line Data1, or it can be connected to multiple first data signal lines Data1 through a multiplexing module or other modules. Similarly, a single second data signal fan-out line Fan2 can also be electrically connected to one or more second data signal lines Data2.

[0080] Please refer to Figure 3 In some embodiments, the aforementioned driver chip DDIC may include a first data signal module 21 and a second data signal module 22.

[0081] The first data signal module 21 can be electrically connected to the first data signal fan-out line Fan1. The first data signal module 21 can generate a first data signal based on the first image data corresponding to the first light-emitting pixel 11 in the image display data received by the driver chip DDIC and the pre-stored first Gamma parameter, and output the first data signal through the first data signal fan-out line Fan1. The first Gamma parameter is the Gamma parameter obtained by the display device in the Gamma adjustment process of the first light-emitting pixel 11 in the display area 1.

[0082] The second data signal module 22 can be electrically connected to the second data signal fan-out line Fan2. The second data signal module 22 can generate a second data signal based on the second image data corresponding to the second light-emitting pixel 12 in the image display data received by the driver chip DDIC and the pre-stored second Gamma parameter, and output the second data signal through the second data signal fan-out line Fan2. The second Gamma parameter is the Gamma parameter obtained by the display device in the Gamma adjustment process of the second light-emitting pixel 12 in the display area 1.

[0083] It is understandable that the brightness attenuation directions of the first light-emitting pixel 11 and the second light-emitting pixel 12 in the display device are not consistent. For example, the brightness attenuation of the first light-emitting pixel 11 is from the first side to the second side of the non-display area 2, while the brightness attenuation direction of the second light-emitting pixel 12 is from the second side to the first side of the non-display area 2. Therefore, when performing Gamma adjustment on the display device, the Gamma adjustment can be performed on the first light-emitting pixel 11 and the second light-emitting pixel 12 separately.

[0084] As an optional implementation, during Gamma adjustment, the first light-emitting pixel 11 can be controlled to emit light while the second light-emitting pixel 12 does not emit light, so as to perform Gamma adjustment on the first light-emitting pixel 11, making the emitted light brightness of the first light-emitting pixel 11 meet the first brightness, and determining the Gamma parameter corresponding to the first brightness. Similarly, by controlling the second light-emitting pixel 12 to emit light while the first light-emitting pixel 11 does not emit light, the Gamma of the second light-emitting pixel 12 can be adjusted, so that the emitted light brightness of the second light-emitting pixel 12 meets the second brightness, and determining the Gamma parameter corresponding to the second brightness.

[0085] The aforementioned first and second brightness levels can be determined based on the target brightness corresponding to each grayscale level of each bound point under different brightness levels. The display device can determine the brightness level corresponding to the brightness range DBVBand corresponding to the DBV (Display Brightness Value). For example, different brightness ranges can correspond to HDR (High Dynamic Range Imaging), HBM (High Brightness Monitor), and multiple Normal brightness levels. Among them, the brightness values ​​of each emitting pixel at the maximum grayscale are higher under the HDR brightness level and the HBM brightness level. For example, the brightness value of the display device at the highest grayscale of the HDR brightness level can reach 1000 nits or more, and the brightness value of the display device at the HBM brightness level can reach 700 nits or more. Multiple Normal brightness levels can correspond to 460 nits, 300 nits, 120 nits, 50 nits, 20 nits, 10 nits, 6 nits, or other emitting brightness, which are not limited here.

[0086] Taking Normal1 brightness level as an example, the target brightness corresponding to a 255-dot grayscale is L, the first brightness is L1, and the second brightness is L2. Since the brightness of the display area should reach the target brightness when both the first emitting pixel 11 and the second emitting pixel 12 are emitting light, the sum of the first brightness and the second brightness should be consistent with the target brightness. That is, at different brightness levels, the target brightness corresponding to each dot grayscale is the sum of the first brightness and the second brightness corresponding to that dot grayscale.

[0087] It is understandable that when the number of first luminous pixels 11 and second luminous pixels 12 in display area 1 is the same, the first brightness and the second brightness are equal, and in this case, L1 = L2 = 1 / 2 * L. When the number of first luminous pixels 11 and second luminous pixels 12 in display area 1 is not the same, the ratio of the first brightness to the second brightness can be the ratio of the number of first luminous pixels 11 to the number of second luminous pixels 12.

[0088] When performing Gamma adjustment on the first light-emitting pixel 11 and the second light-emitting pixel 12 respectively, the first brightness corresponding to each gray level of each binding point can be determined based on the number of the first light-emitting pixel 11 and the second light-emitting pixel 12 in the display area 1, and the target brightness corresponding to each gray level of each binding point under different brightness levels. By adjusting the Gamma register value of the display device, the actual light-emitting brightness of the first light-emitting pixel 11 can meet the first brightness, and the first Gamma parameter corresponding to the first light-emitting pixel 11 can be obtained.

[0089] Similarly, based on the target brightness corresponding to the grayscale of each bound point under different brightness levels, the second brightness corresponding to the grayscale of each bound point under different brightness levels can be determined. By adjusting the Gamma register value of the display device, the actual luminous brightness of the second luminous pixel 12 can meet the second brightness, and the second Gamma parameter corresponding to the second luminous pixel 12 can be obtained.

[0090] Please refer to Figure 4 In some embodiments, the first data signal module 21 may include a first analog-to-digital conversion module 211 and a first data voltage module 212.

[0091] The first analog-to-digital converter module 211 includes two input terminals. The first input terminal can receive a first digital signal corresponding to the first image data, and the second input terminal can receive a first Gamma parameter. The first analog-to-digital converter module 211 can generate a first analog signal based on the first digital signal and the first Gamma parameter.

[0092] The first data voltage module 212 can receive the first analog signal generated by the first analog-to-digital converter 211 and convert the first analog signal into a first data signal so as to drive the corresponding first light-emitting pixel 11 to emit light through the first data signal.

[0093] Similarly, the aforementioned second data signal module 22 may include a second analog-to-digital converter module 221 and a second data voltage module 222. The two input terminals of the second analog-to-digital converter module 221 receive the second digital signal corresponding to the second image data and the second Gamma parameter, respectively. The second analog-to-digital converter module 221 can generate a second analog signal based on the second digital signal and the second Gamma parameter. The second data voltage module 222 can receive the second analog signal generated by the second analog-to-digital converter module 221 and convert it into a second data signal, thereby driving the corresponding second light-emitting pixel 12 to emit light.

[0094] In some embodiments, the first data signal line Data1 and the second data signal line Data2 may be arranged alternately in the display area 1 of the display device.

[0095] In the first direction X within the display area 1, first data signal lines Data1 and second data signal lines Data2 are arranged alternately. In this alternating wiring design, there is no limitation on the number of consecutively adjacent first data signal lines Data1 and second data signal lines Data2. For example, three consecutive first data signal lines Data1 can be arranged, followed by four consecutive second data signal lines Data2, and then two first data signal lines Data1 can be arranged to achieve the alternating arrangement of first data signal lines Data1 and second data signal lines Data2.

[0096] As an optional implementation, the number of the first data signal lines Data1 and the number of the second data signal lines Data2 are the same.

[0097] In one optional implementation, a second data signal line Data2 is provided between any two adjacent first data signal lines Data1, and a first data signal line Data1 is provided between any two adjacent second data signal lines Data2. For example, the odd-numbered columns of data signal lines are the first data signal lines Data1, and the even-numbered columns are the second data signal lines Data2.

[0098] Taking a single first data signal line Data1 as an example, when the first data signal line Data1 extends along the second direction Y, it can be electrically connected to the first light-emitting pixel 11 in the same column, so as to provide corresponding data signals to each first light-emitting pixel 11 sequentially during the row-by-row scanning process. Similarly, the second data signal line Data2 can be electrically connected to the second light-emitting pixel 12 in the same column.

[0099] When the first data signal line Data1 and the second data signal line Data2 are arranged alternately, in order to reduce the length of the signal traces and avoid overlap between them, the light-emitting pixels in the array can be arranged with the first light-emitting pixel 11 and the second light-emitting pixel 12 alternating in columns. For example, the first light-emitting pixel 11 can be set in an odd-numbered column of the light-emitting pixels, and the second light-emitting pixel 12 can be set in an even-numbered column. Alternatively, the first light-emitting pixel 11 can also be set in an even-numbered column, and the second light-emitting pixel 12 can be set in an odd-numbered column.

[0100] As an alternative implementation, the first data signal line Data1 and the second data signal line Data2 can also be arranged in other ways within the display area 1. For example, two adjacent first data signal lines Data1 can be used as a first data line group, and two adjacent second data signal lines Data2 can be used as a second data line group. The first data line group and the second data line group are arranged alternately within the display area 1.

[0101] It is understood that the number of first data signal lines Data1 in the first data line group can be more than two, and the number of second data signal lines Data2 in the second data line group can also be more than two. In multiple alternating first data line groups, the number of first data signal lines Data1 in each first data line group can be the same or different. Correspondingly, in multiple second data line groups, the number of second data signal lines Data2 in each second data line group can also be the same or different.

[0102] Figure 5 A flowchart illustrating a Gamma debugging method according to an embodiment of this application is shown. The Gamma debugging method is applied to a debugging device and can be used to perform Gamma debugging on the display device in the above embodiment. The Gamma debugging method includes:

[0103] S110, in response to the Gamma adjustment command, causes the first data signal to be input to the first light-emitting pixel through the first data signal line, and causes the path for the second light-emitting pixel to receive the second data signal to be cut off.

[0104] S120, based on the first Gamma parameter carried in the Gamma debugging instruction, adjusts the luminous brightness of the first luminous pixel and stores the corresponding first Gamma register value under different luminous brightness;

[0105] S130, the second data signal is input to the second light-emitting pixel through the second data signal line, and the path for the first light-emitting pixel to receive the first data signal is cut off.

[0106] S140, based on the second Gamma parameter carried in the Gamma debugging instruction, adjusts the luminous brightness of the second luminous pixel and stores the corresponding second Gamma register value under different luminous brightness.

[0107] The Gamma adjustment method provided in this application embodiment can be used to perform Gamma adjustment on the display device in the above embodiments. The display device can be a PC, television, smart terminal, or tablet computer, etc. This embodiment does not limit the specific form of the display device.

[0108] In this embodiment, after being connected to the display device, the debugging device responds to a Gamma debugging command by first providing a first data signal to the first emitting pixel through the first data signal line of the display device, and cutting off the path for the second emitting pixel to receive the second data signal. This allows for individual Gamma debugging of the first emitting pixel in the display device using the first Gamma parameter, obtaining the first Gamma register value corresponding to the first emitting pixel under different luminous brightness levels. Then, the path for the first emitting pixel to receive the first data signal is cut off, and a second data signal is provided to the second emitting pixel through the second data signal line. This allows for individual Gamma debugging of the second emitting pixel in the display device using the second Gamma parameter, obtaining the second Gamma register value corresponding to the second emitting pixel under different luminous brightness levels. By separately debugging the first and second emitting pixels, the Gamma register values ​​corresponding to the two types of emitting pixels can be obtained and stored in the storage module of the display device. This enables the display device to provide corresponding data signals to the first and second emitting pixels respectively according to the two Gamma parameters during the display process.

[0109] In S110, for the display device in the above embodiment, in order to make the brightness change during the display satisfy the human eye perception curve when displaying an image, Gamma adjustment can be performed during the production process of the product, and the Gamma register value obtained after Gamma adjustment can be stored in the storage module of the display device, so that when the display device is displaying normally, it generates a corresponding data signal based on the Gamma register value and drives the light-emitting pixels to emit light for display.

[0110] During Gamma tuning, the tuning equipment can connect to the display device, sending data and commands to drive each luminous pixel to emit light, thus displaying the corresponding image content. The tuning equipment can also connect to optical equipment, which can acquire the actual luminous brightness of the display area while the display is active. For example, the optical equipment can acquire the actual luminous brightness of the central area of ​​the display and use it as the overall luminous brightness. The tuning equipment can adjust the display's luminous brightness based on the target brightness corresponding to each grayscale level at the current brightness level and the actual luminous brightness acquired by the optical equipment. When the display's luminous brightness meets the target brightness corresponding to each grayscale level, the tuning equipment can acquire the Gamma register values ​​corresponding to the luminous pixels of different emitted colors at each target brightness.

[0111] The aforementioned grayscale binding points can be a subset of grayscale levels within a grayscale range. Each grayscale binding point can be set to be distributed across different intervals within the grayscale range. When selecting multiple grayscale binding points, a uniform distribution or a non-uniform distribution can be used. For example, since the human eye is more sensitive to low brightness, when selecting grayscale binding points, more grayscale binding points can be set in the low grayscale range, while fewer grayscale binding points can be set in the high grayscale range.

[0112] As an optional implementation, taking a grayscale range of 0-255 as an example, the grayscale of the binding point can be set to 0, 1, 3, 7, 15, 31, 63, 127, 191, 223, 255 grayscale.

[0113] During Gamma debugging, the debugging equipment responds to the Gamma debugging command, causing the first data signal line in the display device to be in a conductive state. At this time, the first data signal can be input to each of the first light-emitting pixels of the display device through the first data signal line, thereby driving each of the first light-emitting pixels to emit light. Meanwhile, the second data signal line is in a cut-off state, and each of the second light-emitting pixels cannot receive the corresponding second data signal and therefore will not emit light.

[0114] In S120, when providing a first data signal to the first light-emitting pixel in the display device through the first data signal line, the first brightness corresponding to the first light-emitting pixel when performing Gamma adjustment at different binding point gray levels can be determined based on the first Gamma parameter carried in the Gamma adjustment instruction. That is, the adjustment device can determine the target brightness corresponding to each binding point gray level at the current brightness level when only the first light-emitting pixel emits light based on the first Gamma parameter carried in the Gamma adjustment instruction.

[0115] Since the overall luminance of the display device is the sum of the luminance of the first luminous pixel and the luminance of the second luminous pixel, at the same grayscale level, the target luminance of the overall display area of ​​the display device should be the sum of the first luminance of the first luminous pixel and the second luminance of the second luminous pixel at that grayscale level. That is, the target luminance corresponding to each grayscale level is the sum of the first luminance and the second luminance at that grayscale level.

[0116] The debugging device can obtain the actual luminous brightness of the display area of ​​the display device through optical equipment when the first luminous pixel emits light, and according to the first brightness corresponding to different binding point gray levels in the first Gamma parameter, obtain the Gamma register value corresponding to the first luminous pixel of different light-emitting colors, so as to obtain the Gamma register value of the first brightness corresponding to each binding point gray level when only the first luminous pixel emits light, and store the first Gamma register value corresponding to different luminous brightness to the storage module of the display device.

[0117] When adjusting the actual luminous brightness of the display device using debugging equipment, if the actual luminous brightness matches each of the first brightness levels, then the Gamma register value corresponding to the first luminous pixel of each emitting color is determined to be the Gamma register value corresponding to that grayscale level. By adjusting the actual luminous brightness to match each of the first brightness levels, the Gamma register values ​​corresponding to different grayscale levels can be obtained. After determining the Gamma register values ​​corresponding to the first luminous pixels of each emitting color at different grayscale levels, the debugging equipment can complete the Gamma adjustment of the first luminous pixel at a single brightness level.

[0118] In S130, similar to the Gamma adjustment process for the first light-emitting pixel described above, the adjustment device can respond to the Gamma adjustment command by making the path of the second data signal line in the display device active. At this time, the second data signal can be input to each of the second light-emitting pixels in the display device through the second data signal line, thereby driving each of the second light-emitting pixels to emit light. Meanwhile, the path of the first data signal line is in a closed state, and each of the first light-emitting pixels cannot receive the corresponding first data signal and therefore will not emit light.

[0119] In S140, when providing a second data signal to the second light-emitting pixel in the display device via the second data signal line, the second brightness corresponding to the second light-emitting pixel when performing Gamma adjustment at different binding point gray levels can be determined based on the second Gamma parameter carried in the Gamma adjustment instruction. That is, the adjustment device can determine the target brightness corresponding to each binding point gray level when only the second light-emitting pixel emits light based on the second Gamma parameter carried in the Gamma adjustment instruction.

[0120] The debugging equipment adjusts the actual luminous brightness of the display device to match each second brightness, and obtains the Gamma register value corresponding to each emitting color of the second luminous pixel when the brightness is matched. This gives the Gamma register value of the second brightness corresponding to each gray level of the binding point when only the second luminous pixel emits light, and stores the second Gamma register value corresponding to different luminous brightness in the storage module of the display device.

[0121] The debugging equipment drives the first and second light-emitting pixels of the display device to emit light. After obtaining the Gamma register values ​​corresponding to the first and second light-emitting pixels at various grayscale levels, respectively, these values ​​can be stored in the display device's storage module. During display, the display device can provide a corresponding data voltage to the first light-emitting pixel using a first data signal line based on the image display data and the Gamma register value of the first light-emitting pixel. Similarly, it can provide a corresponding data voltage to the second light-emitting pixel using a second data signal line based on the image display data and the Gamma register value of the second light-emitting pixel, enabling the first and second light-emitting pixels to emit light under different Gamma parameters.

[0122] As an optional embodiment, the first Gamma parameter includes the first brightness corresponding to the first emitting pixel at each bound point grayscale, and the second Gamma parameter includes the second brightness corresponding to the second emitting pixel at each bound point grayscale. The target brightness of each bound point grayscale is the sum of the first brightness corresponding to the first emitting pixel and the second brightness corresponding to the second emitting pixel.

[0123] The first Gamma parameter mentioned above should include the first brightness corresponding to the first emitting pixel at each bounding grayscale, so that the debugging device can adjust the brightness of the first emitting pixel by changing the data signal voltage provided to the first emitting pixel by adjusting the Gamma register value during the Gamma debugging process. When the actual brightness of the first emitting pixel matches the first brightness at a certain bounding grayscale, the Gamma register value at this time can be used as the Gamma register value corresponding to that bounding grayscale. Similarly, the second Gamma parameter should include the second brightness corresponding to the second emitting pixel at each bounding grayscale, so that the debugging device can adjust the brightness of the second emitting pixel by adjusting the Gamma register value, and when the actual brightness of the second emitting pixel matches the second brightness at each bounding grayscale, obtain the Gamma register value at the matching time as the Gamma register value corresponding to each bounding grayscale.

[0124] Since both the first and second light-emitting pixels are part of all the light-emitting pixels included in the display panel, the first brightness corresponding to when only the first light-emitting pixel is emitting light in a single-dot grayscale should be lower than the target brightness when all the light-emitting pixels of the display device are emitting light. Similarly, the second brightness corresponding to when only the second light-emitting pixel is emitting light in the display device should also be lower than the target brightness when all the light-emitting pixels of the display device are emitting light.

[0125] Taking a single-pixel grayscale as an example, under a single-pixel grayscale, if only the first emitting pixel emits light, it corresponds to a first brightness; and if only the second emitting pixel emits light, it corresponds to a second brightness. Therefore, when both the first and second emitting pixels emit light simultaneously, the luminous brightness of the display device should be consistent with the target brightness corresponding to that grayscale. Since the actual luminous brightness of the display device should be the sum of the first and second brightness when both the first and second emitting pixels emit light simultaneously, in order to ensure that the luminous brightness of the display device is consistent with the target brightness corresponding to that grayscale when both the first and second emitting pixels emit light simultaneously, that is, the sum of the first brightness corresponding to the first emitting pixel and the second brightness corresponding to the second emitting pixel should be the target brightness of that grayscale.

[0126] As an optional implementation, before adjusting the first and second light-emitting pixels of the display device, it is necessary to determine the first brightness and the second brightness corresponding to the first and second light-emitting pixels, respectively.

[0127] When a first data signal line in a display device is connected to a first luminous pixel in the same column, and a second data signal line is connected to a second luminous pixel in the same column, since the number of luminous pixels in each column of the array can be approximately considered to be the same, the ratio of the number of first luminous pixels to the number of second luminous pixels can be converted into the ratio of the number of first data signal lines to the number of second data signal lines. Based on the number of first and second data signal lines provided in the display device, the numerical relationship between the number of first and second luminous pixels in the display area can be determined.

[0128] After determining the ratio of the number of first luminous pixels to the number of second luminous pixels, the first brightness corresponding to the first luminous pixel and the second brightness corresponding to the second luminous pixel can be determined based on the target brightness of each binding point grayscale.

[0129] After determining the first brightness corresponding to each grayscale level of each binding point, the debugging equipment can drive the display device to emit light only from the first emitting pixel. By adjusting the Gamma register value, the voltage of the data signal is adjusted, thereby regulating the actual emitting brightness of the first emitting pixel. By matching the actual emitting brightness with each first brightness, the Gamma register value corresponding to the first emitting pixel at each grayscale level of the binding point can be obtained.

[0130] Similar to the method of obtaining the Gamma register value corresponding to the first light-emitting pixel, after determining the second brightness corresponding to each gray level of the binding point, the debugging device can drive the display device to emit light only to the second light-emitting pixel, so that the actual light-emitting brightness of the second light-emitting pixel when it emits light is matched with each second brightness, and obtain the Gamma register value corresponding to the second light-emitting pixel with different light-emitting colors when matched, and obtain the Gamma register value corresponding to the second light-emitting pixel under each gray level of the binding point.

[0131] By determining the ratio of the number of first and second luminous pixels, the ratio of each first brightness to its corresponding second brightness can be established. Since the sum of the first and second brightnesses equals the target brightness, the first and second brightness corresponding to each grayscale level can be determined based on the ratio of the target brightness to the number of first and second luminous pixels. By adjusting the actual luminance of the first luminous pixel during illumination and matching it with each first brightness, the Gamma register value corresponding to the first luminous pixel at each grayscale level can be determined based on the Gamma register value at the matching point. Similarly, by adjusting the actual luminance of the second luminous pixel during illumination and matching it with each second brightness, the Gamma register value corresponding to the second luminous pixel at each grayscale level can be determined.

[0132] In some embodiments, at a single brightness level, substituting the Gamma value into the grayscale brightness formula can determine the target brightness corresponding to each bound point grayscale. Since the light-emitting pixels of the display device are composed of a first light-emitting pixel and a second light-emitting pixel, when the first light-emitting pixel emits light alone, each bound point grayscale corresponds to a first brightness; when the second light-emitting pixel emits light alone, each bound point grayscale corresponds to a second brightness.

[0133] In some embodiments, after determining that the sum of the first brightness and the second brightness is the target brightness corresponding to each grayscale level of the binding point, since the ratio of the number of first emitting pixels to the number of second emitting pixels can be predetermined, this ratio can be used as the ratio of the first brightness to the second brightness. Therefore, based on the target brightness corresponding to each grayscale level of the binding point and the ratio of the number of first emitting pixels to the number of second emitting pixels, the first brightness and the second brightness corresponding to each grayscale level of the binding point can be determined.

[0134] Taking HBM as an example, the Gamma value can be 2.2 or other values. In the grayscale range of 0-255, based on the target brightness corresponding to the maximum binding point grayscale of 255, the target brightness corresponding to each of the other binding point grayscales can be determined. Taking one of the binding point grayscales as an example, according to the grayscale brightness formula, the target brightness L corresponding to that binding point grayscale can be calculated using the target brightness at grayscale 255 and Gamma 2.2. After determining the target brightness L corresponding to that binding point grayscale, the first brightness L1 corresponding to the first emitting pixel and the second brightness L2 corresponding to the second emitting pixel can be determined based on the ratio of the number of first emitting pixels to the number of second emitting pixels. The sum of L1 and L2 is the target brightness L corresponding to that binding point grayscale, and the ratio of L1 to L2 is the ratio of the number of first emitting pixels to the number of second emitting pixels.

[0135] It should be noted that when the first data signal line and the second data signal line are arranged alternately, the ratio of the number of first luminous pixels to the number of second luminous pixels can be approximated as 1. In this case, the first brightness L1 corresponding to the first luminous pixel is equal to the second brightness L2 corresponding to the second luminous pixel. That is, L1 = L2 = 1 / 2 * L.

[0136] After determining the target brightness corresponding to each grayscale of each bound point under the HBM brightness level, the first brightness and second brightness corresponding to the target brightness of each bound point grayscale can be determined by using the ratio of the number of first emitting pixels to the number of second emitting pixels.

[0137] Similarly, at other brightness levels, such as HDR, Normal1, and Normal2, the ratio of the number of first emitting pixels to the number of second emitting pixels can be used to determine the first and second brightness corresponding to each grayscale of each bound point at each brightness level.

[0138] As an optional embodiment, if the number of first light-emitting pixels and the number of second light-emitting pixels in the display device are the same, then under a single bound-point grayscale, the first brightness corresponding to the first light-emitting pixel is half of the target brightness of the bound-point grayscale, and the second brightness corresponding to the second light-emitting pixel is also half of the target brightness of the bound-point grayscale.

[0139] In this embodiment, since the number of first light-emitting pixels is the same as the number of second light-emitting pixels, at each binding point grayscale, the first brightness of the first light-emitting pixel is half of the target brightness corresponding to that binding point grayscale, and the second brightness of the second light-emitting pixel is also half of the target brightness corresponding to that binding point grayscale.

[0140] Taking a single bound-point grayscale as an example, when adjusting the Gamma of the bound-point grayscale, the first data signal line can be turned on and the second data signal line can be turned off to provide the corresponding data voltage to the first light-emitting pixel through the first data signal line. The data voltage can be adjusted by adjusting the Gamma register value so that the actual light-emitting brightness of the first light-emitting pixel in the display area of ​​the display device matches the first brightness, that is, half of the target brightness of the bound-point grayscale.

[0141] It is understandable that when data voltage is provided through the first data signal line, the second data signal line does not provide data voltage, and at this time, none of the second light-emitting pixels emit light.

[0142] When the actual luminance of the first luminous pixel meets the first luminance, the Gamma register value at this time can be used as the Gamma register value of the first luminous pixel under the grayscale of that binding point.

[0143] After determining the Gamma register value of the first luminous pixel, a similar approach can be used to turn on the second data signal line and turn off the first data signal line, so as to provide the corresponding data voltage to the second luminous pixel through the second data signal line, and adjust the data voltage by adjusting the Gamma register value, so that the actual luminous brightness of the second luminous pixel in the display area of ​​the display device matches the second brightness, that is, half of the target brightness of the grayscale of the binding point, and finally obtain the Gamma register value corresponding to the second luminous pixel satisfying the second brightness as the Gamma register value of the second luminous pixel under the grayscale of the binding point.

[0144] It should be noted that when adjusting the Gamma of a single grayscale point, the order of adjustment of the first and second emitting pixels can be interchanged. For example, the first emitting pixel can be adjusted first through the first data signal line, or the second emitting pixel can be adjusted first through the second data signal line.

[0145] Under the Gamma adjustment of a single-point grayscale, after obtaining the Gamma register value of the first luminous pixel and the Gamma register value of the second luminous pixel, data voltage can be provided simultaneously through the first data signal line and the second data signal line. At this time, both the first luminous pixel and the second luminous pixel emit light.

[0146] The data voltage provided by the first data signal line is the data voltage corresponding to the Gamma register value of the first emitting pixel, while the data voltage provided by the second data signal line is the data voltage corresponding to the Gamma register value of the second emitting pixel. By providing the two data signal lines with data voltages corresponding to the Gamma register values ​​of the two emitting pixels respectively, independent Gamma adjustment of the two emitting pixels can be achieved.

[0147] Since the actual luminance of the first emitting pixel is half the target luminance of the grayscale level at a single binding point when the first data signal line provides the data voltage corresponding to that grayscale level, and the actual luminance of the second emitting pixel is also half the target luminance of the grayscale level at a single binding point when the second data signal line provides the data voltage corresponding to that grayscale level, the overall luminance of the display area obtained by the optical device when the first and second emitting pixels emit light simultaneously is the target luminance of the grayscale level at the binding point.

[0148] This application embodiment also provides a driving method for a display device, which is applied to the display device. The display device stores a first Gamma register value and a second Gamma register value obtained through the above-described Gamma adjustment method. The driving method for the display device includes:

[0149] S210, Obtain image data of the image to be displayed;

[0150] S220, based on multiple first Gamma register values ​​corresponding to the first Gamma parameter, determine the third Gamma register value corresponding to the first luminous pixel according to the portion of image data corresponding to the first luminous pixel in the image data, so as to drive the first luminous pixel through the data signal corresponding to the third Gamma register value;

[0151] S230, based on multiple second Gamma register values ​​corresponding to the second Gamma parameter, determine the fourth Gamma register value corresponding to the second luminous pixel according to the portion of image data corresponding to the second luminous pixel in the image data, so as to drive the second luminous pixel through the data signal corresponding to the fourth Gamma register value.

[0152] In S210, after the Gamma adjustment method described in the above embodiment, it is possible to store the first Gamma register value corresponding to the first emitting pixel and the second Gamma register value corresponding to the second emitting pixel under different luminous brightness levels. During the image display process of the display device, the first emitting pixel and the second emitting pixel can be driven to emit light according to the two Gamma parameters respectively.

[0153] During the image display process, the display device can acquire image data of the image to be displayed. This image data may contain the display grayscale corresponding to each luminous pixel of the display device.

[0154] In S220, the display device can determine a portion of image data corresponding to the first light-emitting pixel from the image data. This portion of the first image data may include the display grayscale of each first light-emitting pixel.

[0155] The display device can determine the third Gamma register value corresponding to the display grayscale of each first luminous pixel based on the multiple first Gamma register values ​​corresponding to the first Gamma parameter, and provide corresponding data signals to each first luminous pixel according to the third Gamma register value of each first luminous pixel, so as to drive the first luminous pixel to emit light through the first Gamma parameter.

[0156] In S230, similar to the principle of the display device driving the first light-emitting pixel, the display device can determine a portion of image data corresponding to the second light-emitting pixel from the image data. This portion of the second image data may include the display grayscale of each second light-emitting pixel.

[0157] The display device can determine the fourth Gamma register value corresponding to the display grayscale of each second light-emitting pixel based on the multiple second Gamma register values ​​corresponding to the second Gamma parameter, and provide corresponding data signals to each second light-emitting pixel according to the fourth Gamma register value of each second light-emitting pixel, so as to drive the second light-emitting pixel to emit light through the second Gamma parameter.

[0158] In this embodiment, the display device can determine the third Gamma register value required for the first luminous pixel to emit light according to the image to be displayed, based on multiple first Gamma register values ​​corresponding to the first Gamma parameter and the image data corresponding to the first luminous pixel, and drive the first luminous pixel to emit light through the data signal corresponding to the third Gamma register value. Similarly, the display device can also determine the fourth Gamma register value required for the second luminous pixel to emit light according to the image to be displayed, based on multiple second Gamma register values, and drive the second luminous pixel to emit light through the data signal corresponding to the fourth Gamma register value. By calling the first Gamma parameter and the second Gamma parameter to drive the first luminous pixel and the second luminous pixel to emit light respectively, the difference in luminous brightness between various display areas is reduced, and the phenomenon of uneven display brightness caused by the different luminous brightness of luminous devices at different positions is improved.

[0159] As an optional implementation, taking a single grayscale image as an example, the single grayscale image is the first grayscale image. Based on the image data of the image to be displayed, the display device can determine that the display grayscale of each first luminous pixel is the first grayscale, and the display grayscale of each second luminous pixel is also the first grayscale.

[0160] The display device can determine the third Gamma register value corresponding to the first grayscale based on multiple first Gamma register values ​​corresponding to the first Gamma parameter.

[0161] When the first gray level is a bound point gray level, the first Gamma register value that matches the bound point gray level can be directly determined from multiple first Gamma register values ​​as the third Gamma register value.

[0162] When the first gray level is not a bound point gray level, at least two bound point gray levels adjacent to the first gray level can be obtained. The two first Gamma register values ​​corresponding to the two bound point gray levels are used for interpolation calculation to obtain the third Gamma register value corresponding to the first gray level.

[0163] After obtaining the third Gamma register value corresponding to the first gray level, a data signal can be provided to the first luminous pixel based on the data voltage corresponding to the third Gamma register value.

[0164] Similarly, the display device can also determine the fourth Gamma register value corresponding to the first grayscale based on multiple second Gamma register values ​​corresponding to the second Gamma parameter. After obtaining the fourth Gamma register value corresponding to the first grayscale, a data signal can be provided to the second emitting pixel according to the data voltage corresponding to the fourth Gamma register value.

[0165] At the current brightness level, the target brightness of the display device corresponding to the first grayscale can be obtained based on the target brightness at the maximum grayscale and the Gamma coefficient (usually 2.2). When the first emitting pixel is driven to emit light by the third Gamma register value corresponding to the first grayscale, and the second emitting pixel is driven to emit light by the fourth Gamma register value corresponding to the first grayscale, the sum of the first brightness of the first emitting pixel and the second brightness of the second emitting pixel when both are emitting light simultaneously is the target brightness of the first grayscale. Therefore, when the first and second emitting pixels emit light simultaneously, the overall luminous brightness of the display device is the target brightness of the first grayscale.

[0166] This application also provides a debugging device, such as... Figure 6 As shown, the debugging device includes:

[0167] The first driving module 601 is used to respond to the Gamma debugging command to input the first data signal to the first light-emitting pixel through the first data signal line, and to cut off the path for the second light-emitting pixel to receive the second data signal.

[0168] The first debugging module 602 is used to adjust the luminous brightness of the first luminous pixel based on the first Gamma parameter carried in the Gamma debugging instruction, and to store the first Gamma register value corresponding to different luminous brightness.

[0169] The second driving module 603 is used to input the second data signal to the second light-emitting pixel through the second data signal line, and to cut off the path for the first light-emitting pixel to receive the first data signal.

[0170] The second debugging module 604 is used to adjust the luminous brightness of the second luminous pixel based on the second Gamma parameter carried in the Gamma debugging instruction, and to store the corresponding second Gamma register values ​​under different luminous brightness.
