[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0028] See also Figure 1 , which shows a schematic diagram of an application scenario of a display screen control system provided in an embodiment of the present application, which may include a display control device 100 and an LED display device 200. The display control device 100 may be communicatively connected to the LED display device 200 and perform data exchange with the LED display device 200.

[0029] The display control device 100 can be connected to the LED display device 200 by means of cable communication and the like, and perform data exchange with the LED display device 200. The display control device 100 can be a receiving card, a T-con (Timing Control) chip, a receiving card integrated with a Field Programmable Gate Array (FPGA) chip, or a receiving card integrated with a System on Chip (Soc).

[0030] The LED display device 200 may include a driver chip 210 and an LED display screen 220. The driver chip 210 may be communicatively connected to the display control device 100 and the LED display screen 220. The driver chip 210 may receive control parameters sent by the display control device 100 and control the LED display screen 220 to perform light-emitting display according to the control parameters. The driver chip 210 may be a driver integrated circuit (IC) chip.

[0031] In some embodiments, the driver chip 210 may be more than two driver chipsets, each driver chipset including a red sub-pixel driver chip, a green sub-pixel driver chip, and a blue sub-pixel driver chip, etc. The red sub-pixel driver chip, the green sub-pixel driver chip, and the blue sub-pixel driver chip in each driver chipset may be connected in parallel between the display control device 100 and the LED display screen 220 through a data channel; the sub-pixel driver chips of the same type in adjacent driver chipsets may be connected in series between the display control device 100 and the LED display screen 220 through a signal channel.

[0032] When the user performs display control on the LED display screen 220, the user can input the image to be displayed into the display control device 100, and the display control device 100 receives the image to be displayed, obtains the current grayscale data corresponding to the image to be displayed, and determines the target grayscale data corresponding to the image to be displayed according to the target current value and the current grayscale data corresponding to the image to be displayed, and sends the target current value and the target grayscale data to the driver chip 210, and the driver chip 210 receives and responds to the target current value and the target grayscale data, and controls the LED display screen 220 to work with the target current value and the target grayscale value, thereby realizing the display control process of the LED display screen 220. The grayscale data can be used to characterize the grayscale level of the image to be displayed on the LED display screen 220, and the grayscale data can be pulse width modulation (PWM) grayscale data.

[0033] See also Figure 2, which shows a flow chart of a display screen control method provided by an embodiment of the present application. In a specific embodiment, the display screen control method can be applied to Figure 1 The display control device 100 in the display screen control system shown in FIG. 1 is taken as an example below. Figure 2 The process shown is described in detail, and the display screen control method may include the following steps S110 to S130.

[0034] Step S110: obtaining current grayscale data corresponding to the target pixel address of the LED display screen.

[0035] In the embodiment of the present application, the LED display screen is an electronic display screen composed of LED dot matrix (LED lamp beads, referred to as LED), and the text, animation, picture or video, etc. are displayed on the electronic display screen by turning on and off the LED. Among them, the LED can be at least any one of the combinations of red LED lamp beads, green LED lamp beads, blue LED lamp beads, RGB LED lamp beads or RGBW LED lamp beads, and each LED corresponds to a pixel address of the LED display screen. Grayscale data can be used to characterize the grayscale level of the displayed image of the LED display screen, and the grayscale data can be pulse width modulation (PWM) grayscale data.

[0036] When a user controls the display of an LED display screen, the user can input a display image into a display control device. The display control device receives and responds to the display image, determines the target display data corresponding to the LED dot matrix based on the correspondence between the display image and the LED dot matrix, and analyzes the target display image to obtain the current grayscale data corresponding to the target display image, that is, the current grayscale data corresponding to the target pixel address of the LED display screen.

[0037] Step S120: determining corresponding target grayscale data according to the target current value corresponding to the target pixel address and the current grayscale data.

[0038] In an embodiment of the present application, the target current value is the operating current value when the LED display screen displays the current frame image, and the target current value corresponds to the target pixel address of the LED display screen; the target grayscale data is the grayscale data corresponding to the current frame image of the LED display screen.

[0039] After acquiring the current grayscale data corresponding to the target pixel address of the LED display screen, the display control device can determine the target grayscale data corresponding to the target pixel address according to the target current value corresponding to the target pixel address and the current grayscale data.

[0040] Specifically, after obtaining the current grayscale data corresponding to the target pixel address of the LED display screen, the display control device can determine the target driver chip address corresponding to the target pixel address based on the target pixel address, and obtain the target current value corresponding to the target driver chip address based on the target driver chip address, and determine the corresponding compensation coefficient table based on the target current value, and search the compensation coefficient table based on the current grayscale data to obtain the target compensation coefficient corresponding to the current grayscale data, and calculate the product of the current grayscale data and the target compensation coefficient to obtain the target grayscale data.

[0041] Among them, the compensation coefficient table can be used to characterize the correspondence between grayscale data and compensation coefficients. The compensation coefficient table can be a table preset by the user, or a table automatically generated by the display control device according to the user's historical display control process of the LED display screen.

[0042] For example, the correspondence between grayscale data and compensation coefficients may be as shown in Table 1, ie, a compensation coefficient table. Table 1 shows compensation coefficients corresponding to different grayscale data. According to the correspondence, the target compensation coefficient corresponding to the current grayscale data may be obtained.

[0043] Table 1

[0044] Grayscale data Compensation coefficient 50 1.1 100 1.2 150 1.3 200 1.5 250 1.8

[0045] It should be noted that the correspondence between grayscale data and compensation coefficients is not limited to that shown in Table 1, and can be set according to actual needs. In addition, the compensation coefficient table can also be a function or curve reflecting the correspondence between grayscale data and compensation coefficients.

[0046] In the embodiment of the present application, based on the different current response characteristics of the RGB LED, the RGB LED has different preset current gain coefficients. Therefore, the RGB LED generates corresponding target current values ​​based on different preset current gain coefficients. The display control device can obtain the corresponding reference current value according to the target driver chip address, and obtain the corresponding target current value according to the reference current value and the preset current gain coefficient. Among them, the reference current value is a pre-stored current value, and the reference current value corresponds to the target pixel address.

[0047] In some embodiments, the LED display control system may further include a storage module, which may be communicatively connected to the display control device and perform data exchange with the display control device; the storage module may pre-store a target current value corresponding to a target pixel address of the LED display.

[0048] After acquiring the current grayscale data corresponding to the target pixel address of the LED display screen, the display control device can send a current acquisition instruction carrying the target pixel address to the storage module. The storage module receives and responds to the current acquisition instruction sent by the display control device, and sends a pre-stored target current value to the display control device. The target current value corresponds to the target pixel address. The display control device receives the target current value returned by the storage module.

[0049] In some embodiments, the display control device is provided with a storage unit. For example, the storage unit may be integrated in the display control device. The storage unit pre-stores a target current value corresponding to a target pixel address of the LED display screen.

[0050] After acquiring the current grayscale data corresponding to the target pixel address of the LED display screen, the display control device can read the corresponding target current value from the storage unit according to the target pixel address.

[0051] In some embodiments, in order to avoid excessive brightness changes of the LED display screen during the switching process of two adjacent frames of the LED display screen, the operating current value corresponding to the current frame image of the LED display screen can be a current value calculated based on the previous frame image of the LED display screen. Among them, the operating current value of the first frame image when the LED display screen is turned on can be set to any current value less than the rated current of the LED display screen.

[0052] The display control device can calculate the current grayscale characteristic value corresponding to the current grayscale data according to the maximum value and average value of the current grayscale data, and according to the current grayscale characteristic value, search the preset ammeter to obtain the corresponding current current value, and send the update instruction carrying the current current value to the storage module. The storage module receives and responds to the update instruction, and replaces the original stored target current value with the current current value as the updated target current value, which can avoid a large change in the display brightness when the LED display screen switches to the next frame image, and further improves the display effect of the LED display screen. For example, the target current value used by the current frame A frame is obtained based on the characteristic grayscale value of the previous frame A' frame based on the ammeter search, and is called from the memory for use; the current frame A frame also needs to obtain a new target current value based on the ammeter search according to its own characteristic grayscale value, and update it in the memory to replace the current value generated by the original A' frame, which is used to be called as the target current value of the next frame B frame.

[0053] For another example, if the current frame is the first frame of the picture, and there is no target current value generated by the previous frame for use, then the target current value used for the current first frame can be manually set by professionals, or generated by software through algorithms, etc. Possible implementation methods are not limited to this.

[0054] The current grayscale feature value can be used to characterize the grayscale weighted value. The current grayscale data may include maximum grayscale data Grey_max and mean grayscale data Gey_ave. The display control device may calculate the corresponding current grayscale feature value according to formula 1 based on the preset maximum grayscale data weight Ration_Grey_max, the preset mean grayscale data weight Ration_Grey_ave, the maximum grayscale data Grey_max and the mean grayscale data Gey_ave.

[0055] Formula 1 is: Chara-Grey=Ration-Grey-max·Grey-max+Ration-Grey-ave·Grey-ave, wherein Chara_Grey is the current grayscale eigenvalue.

[0056] The ammeter can be used to characterize the correspondence between the grayscale characteristic value and the current value. The ammeter can be a table preset by the user, or a table automatically generated by the display control device according to the user's historical display control process of the LED display screen.

[0057] For example, the correspondence between the grayscale characteristic value and the current value may be as shown in Table 2, ie, a preset current table. Table 2 shows the current values ​​corresponding to different grayscale characteristic values. According to the correspondence, the current current value corresponding to the current grayscale characteristic value may be obtained.

[0058] Table 2

[0059] Grayscale eigenvalue Current value (mA) 55 5 110 15 155 20 210 30 255 50

[0060] It should be noted that the correspondence between the grayscale characteristic value and the current value is not limited to that shown in Table 2, and can be specifically set according to actual needs. In addition, the current table can also reflect the function or curve of the correspondence between the grayscale characteristic value and the current value.

[0061] In some embodiments, different current values ​​correspond to different compensation coefficient tables. After obtaining the current grayscale data corresponding to the target pixel address of the LED display screen, the display control device can obtain the target current value corresponding to the target pixel address according to the target pixel address, and obtain the corresponding compensation coefficient table from multiple preset coefficient tables according to the target current value. The preset coefficient table can be used to characterize the corresponding relationship between the current value and the compensation coefficient table.

[0062] For example, the compensation coefficient table may include A, B, C, D, and E. The correspondence between the current value and the compensation coefficient table may be as shown in Table 3, that is, the preset coefficient table. Table 3 shows the compensation coefficient table corresponding to different current values. Based on the correspondence, the compensation coefficient table corresponding to the target current value can be obtained.

[0063] Table 3

[0064] Current value (mA) Compensation coefficient table 10 A 20 B 50 C 100 D 150 E

[0065] It should be noted that the correspondence between the current value and the compensation coefficient table is not limited to that shown in Table 3, and can be set according to actual needs. In addition, the preset coefficient table can also be a function or curve reflecting the correspondence between the current value and the compensation coefficient table.

[0066] In some embodiments, the target compensation coefficient may include a white compensation coefficient and an RGB compensation coefficient. The display control device may calculate the white compensation coefficient weight and the RGB compensation coefficient weight corresponding to the current grayscale data based on the current grayscale data, and calculate the product of the white compensation coefficient, the white compensation coefficient weight and the current grayscale data to obtain the target white grayscale data, and calculate the product of the RGB compensation coefficient, the RGB compensation coefficient weight and the current grayscale data to obtain the target RGB grayscale data, and calculate the sum of the target white grayscale data and the target RGB grayscale data to obtain the target grayscale data, that is, the display control device calculates the corresponding target grayscale data based on the current grayscale data and the target compensation coefficient, thereby achieving a display effect that takes into account both white and monochrome of the LED display screen, and further improving the display effect of the LED display screen.

[0067] Among them, the display control device can calculate the saturation corresponding to the current grayscale data according to the current grayscale data, and calculate the white compensation coefficient weight and the RGB compensation coefficient weight corresponding to the saturation according to the saturation.

[0068] In an application scenario, the current grayscale data may include maximum grayscale data MAX(R, G, B) and minimum grayscale data MIN(R, G, B). The display control device may calculate the corresponding saturation S according to formula 2 based on the maximum grayscale data MAX(R, G, B) and the minimum grayscale data MIN(R, G, B).

[0069] Formula 1 is: Where S is the saturation, and the saturation S can include the maximum saturation S max and the minimum saturation S min .

[0070] And according to the saturation, preset maximum saturation S maxAnd the preset minimum saturation S min , calculate the RGB compensation coefficient weight according to formula three.

[0071] Formula three is: Ratio_RGB is the RGB compensation coefficient weight.

[0072] And according to the RGB compensation coefficient weights, the white compensation coefficient weight is calculated according to formula 4.

[0073] Formula 4 is: Ratio_W=1-Ratio_RGB, where Ratio_W is the weight of the white compensation coefficient.

[0074] Step S130: sending the target current value and the target grayscale data to the target driver chip corresponding to the target pixel address, so that the target driver chip controls the target LED pixel point corresponding to the target pixel address to emit light based on the target current value and the target grayscale data.

[0075] In the embodiment of the present application, after the display control device determines the corresponding target grayscale data according to the target current value corresponding to the target pixel address and the current grayscale data, the target current value and the target grayscale data can be sent to the target driver chip corresponding to the target pixel address. The target driver chip receives and responds to the target current value and the target grayscale data sent by the display control device, and controls the target LED pixel point corresponding to the target pixel address to work based on the target current value and the target grayscale data, thereby achieving the control of the corresponding target LED pixel point to work according to the target current value and the target grayscale data corresponding to the target pixel address, and the LED display screen has a high grayscale display accuracy at low grayscales, thereby improving the display effect of the LED display screen. Among them, the target driver chip corresponds to the target pixel address of the LED display screen.

[0076] In some embodiments, Figure 3 As shown, it shows a structural block diagram of a display screen control system. The target driver chip can be more than two driver chip groups, each driver chip group can include a red sub-pixel driver chip, a green sub-pixel driver chip, and a blue sub-pixel driver chip, etc. The red sub-pixel driver chip, the green sub-pixel driver chip, and the blue sub-pixel driver chip in each driver chip group can be connected in parallel between the display control device and the LED display screen through a data channel; the same type of sub-pixel driver chips in adjacent driver chip groups can be connected in series between the display control device and the LED display screen through a signal channel.

[0077] The target current value may include a first current value, a second current value, and a third current value, the target pixel grayscale data may include first grayscale data corresponding to the first current value, second grayscale data corresponding to the second current value, and third grayscale data corresponding to the third current value, and the target pixel address may include a first pixel address corresponding to the first grayscale data, a second pixel address corresponding to the second grayscale data, and a third pixel address corresponding to the third grayscale data.

[0078] After determining the corresponding target grayscale data based on the target current value corresponding to the target pixel address and the current grayscale data, the display control device can simultaneously send the first current value and the first grayscale data to the red sub-pixel driver chip, send the second current value and the second grayscale data to the green sub-pixel driver chip, and send the third current value and the third grayscale data to the blue sub-pixel driver chip, so that the red sub-pixel driver chip controls the first target LED pixel point corresponding to the first pixel address to display red light based on the first current value and the first grayscale data, and the green sub-pixel driver chip controls the second target LED pixel point corresponding to the second pixel address to display green light based on the second current value and the second grayscale data, and the blue sub-pixel driver chip controls the third target LED pixel point corresponding to the third pixel address to display blue light based on the third current value and the third grayscale data, thereby realizing parallel display control of red light, green light and blue light of the LED display screen.

[0079] The solution provided by the present application obtains the current grayscale data corresponding to the target pixel address of the LED display screen, determines the corresponding target grayscale data according to the target current value corresponding to the target pixel address and the current grayscale data, and sends the target current value and the target grayscale data to the target driver chip corresponding to the target pixel address, so that the target driver chip controls the target LED pixel point corresponding to the target pixel address to operate based on the target current value and the target grayscale data. This method realizes controlling the corresponding target LED pixel point to operate according to the target current value and the target grayscale data corresponding to the target pixel address. The LED display screen has a high grayscale display accuracy at low grayscales, thereby improving the display effect of the LED display screen.

[0080] See also Figure 4 , which shows a flow chart of a display screen control method provided by another embodiment of the present application. In a specific embodiment, the display screen control method can be applied to Figure 1 The display control device 100 in the display screen control system shown in FIG. 1 is taken as an example below. Figure 4 The process shown is described in detail, and the display screen control method may include the following steps S210 to S240.

[0081] Step S210: obtaining current grayscale data corresponding to the target pixel address of the LED display screen.

[0082] In this embodiment, step S210 may refer to the contents of the corresponding steps in the aforementioned embodiments, which will not be described in detail here.

[0083] Step S220: In response to the preset mode selection operation, determine the corresponding target current value.

[0084] In this embodiment, the preset modes may include a high brightness working mode, a standard brightness working mode, a low brightness working mode, etc. The display control device may receive and respond to a preset mode selection operation, and determine a corresponding target current value according to the selected preset mode.

[0085] Specifically, the display control device receives and responds to a preset mode selection operation, can obtain a preset current parameter range corresponding to the preset mode, and display a current parameter adjustment control, and when receiving an adjustment operation on the current parameter adjustment control, receives and responds to the adjustment operation on the current parameter adjustment control, determines the corresponding current parameter from the preset current parameter range, and obtains the corresponding target current value.

[0086] Among them, the display control device receives and responds to the adjustment operation of the current parameter adjustment control, determines the corresponding target adjustment ratio, and obtains the corresponding current parameter from the preset ratio current table according to the target adjustment ratio. The preset ratio current table can be used to characterize the corresponding relationship between the target adjustment ratio and the current parameter. The preset ratio current table can be a table pre-set by the user, or a table automatically generated by the display control device according to the user's historical display control process of the LED display screen. In addition, the preset ratio current table can also be a function or curve reflecting the corresponding relationship between the target adjustment ratio and the current parameter.

[0087] Step S230: determining corresponding target grayscale data according to the current grayscale data and the target current value.

[0088] Step S240: sending the target current value and the target grayscale data to the target driver chip corresponding to the target pixel address, so that the target driver chip controls the target LED pixel point corresponding to the target pixel address to emit light based on the target current value and the target grayscale data.

[0089] In this embodiment, step S230 and step S240 may refer to the contents of the corresponding steps in the aforementioned embodiments, which will not be described in detail here.

[0090] In some embodiments, after the display control device determines the corresponding target grayscale data according to the current grayscale and the target current value, it can determine whether the target current value is within the preset current range, and when it is determined that the target current value is not within the preset current range, the corresponding preset display parameters are determined according to the current grayscale data. The preset display parameters can be used to characterize the preset mode of the LED display screen, and the preset display parameters are sent to the target driver chip. The target driver chip receives and responds to the preset display parameters, and controls the target LED pixel points corresponding to the target pixel address of the LED display screen to operate based on the preset mode. This achieves that when the target current value is not within the preset current range, the LED display screen is controlled to operate according to the preset display parameters corresponding to the current grayscale data, which can ensure that the target working state of the LED display screen is always in a normal working state when performing display work, thereby ensuring that the LED display screen has a long service life.

[0091] The preset current range can be used to characterize the working current range when the working state of the LED display is in a normal working state. The display control device can determine whether the target current value is within the preset current range, thereby determining whether the target working state when the LED display works at the target current value is a normal working state.

[0092] When the target current value is within the preset current range, the target working state of the LED display when working at the target current value is determined to be a normal working state; when the target current value is not within the preset current range, the target working state of the LED display when working at the target current value is determined to be an abnormal working state.

[0093] The display control device can respectively calculate a first current difference value of the target current value minus the minimum current value of the preset current range, and a second current difference value of the maximum current value of the preset current range minus the target current value, and determine whether the target current value is within the preset current range based on the first current difference value and the second current difference value.

[0094] If the first current difference is greater than or equal to zero, and the second current difference is greater than or equal to zero, it is determined that the target current value is within the preset current range, indicating that the target working state of the LED display screen when working at the target current value is a normal working state; if not, it is determined that the target current value is not within the preset current range, indicating that the target working state of the LED display screen when working at the target current value is an abnormal working state.

[0095] When the display control device determines that the target current value is not within the preset current range, it means that the target working state of the LED display when operating at the target current value is an abnormal working state. The display control device can determine the preset display parameters corresponding to the current grayscale data based on the current grayscale data. The preset display parameters can be used to characterize the preset mode of the LED display.

[0096] When the display control device determines that the target current value is not within the preset current range, the preset display parameter lookup table can be searched according to the current grayscale data to obtain the preset display parameters corresponding to the current grayscale data. The preset display parameter table can be used to characterize the correspondence between the grayscale data and the display parameters. The preset display parameter table can be a table pre-set by the user, or a table automatically generated by the display control device according to the user's historical display control process of the LED display screen, or a function or curve reflecting the correspondence between the grayscale data and the display parameters.

[0097] For example, the display parameter may be display brightness (cd / m2). 2 )) Or, the correspondence between grayscale data and display parameters can be as shown in Table 4, that is, the preset display parameter table. Table 4 shows the display parameters corresponding to different grayscale data. According to the correspondence, the preset display parameters corresponding to the current grayscale data can be obtained.

[0098] Table 4

[0099] Grayscale data <![CDATA[Display parameter (cd / m 2 )]]> 45 500 120 1500 160 2000 220 3500

[0100] It should be noted that the correspondence between grayscale data and display parameters is not limited to that shown in Table 4, and can be set according to actual needs. In addition, the preset display parameter table can also be a function or curve reflecting the correspondence between grayscale data and display parameters.

[0101] The solution provided in this embodiment obtains the current grayscale data corresponding to the target pixel address of the LED display screen, responds to the preset mode selection operation, determines the corresponding target current value, and determines the corresponding target grayscale data based on the current grayscale data and the target current value, and sends the target current value and the target grayscale data to the target driver chip corresponding to the target pixel address, thereby achieving control of the corresponding target LED pixel point for luminous display based on the current grayscale data and the preset mode selection operation, and the LED display screen has a high grayscale display accuracy at low grayscales, thereby improving the display effect of the LED display screen.

[0102] Furthermore, when it is determined that the target current value is not within the preset current range, the corresponding preset display parameters are determined according to the current grayscale data, and the preset display parameters are sent to the target driver chip, so that when the target current value is not within the preset current range, the LED display screen is controlled to work according to the preset display parameters corresponding to the current grayscale data, which can ensure that the target working state of the LED display screen is always in a normal working state when it performs display work, thereby ensuring that the LED display screen has a long service life.
