An embodiment of the present invention provides a display panel voltage configuration method, which is applied to a display panel 100, a top view of the display panel 100 is shown in fig. 1, the display panel 100 includes a first display area 1 and a second display area 2 arranged along a first direction y, and a data line extending along the first direction y is disposed in the display area.
As shown in fig. 2, a schematic flow chart of the display screen voltage configuration method includes:
s101, display information of a display screen is acquired.
Wherein the display information is used for reflecting the gray-scale value of the display picture.
S102, entering a split screen display mode, and acquiring a first gamma adjustment standard and a second gamma adjustment standard.
The gamma adjustment standard is the corresponding relation between the gray scale value of the display frame and the voltage output to the data. The voltage outputted by the data line is provided by a driving chip 505 (as shown in fig. 1) of the display panel 100, and in order to simplify the circuit structure of the display panel 100 and reduce the area of the non-display region of the display panel 100, the driving chip 505 is usually disposed on one side of the display panel 100, that is, the driving chip 505 is disposed on the end far away from the first display region 1 or the driving chip 505 is disposed on the end near the first display region 1.
Due to the adoption of the one-sided arrangement of the display driving chip 505, the distances from the voltage output end of the driving chip 505 to the first display area 1 and the second display area 2 are different, that is, the lengths of the corresponding data lines in the first display area 1 and the corresponding data lines in the second display area 2 are different. Because the data line has line impedance, the longer the data line is, the higher the line impedance is, and the greater the line loss is. Therefore, in the split-screen display mode, if the voltages output to the first display area 1 and the second display area 2 by the driving chip 505 are the same, the voltages actually supplied to the first display area 1 and the second display area 2 for operation after being transmitted through the corresponding data lines are different, so that in order to avoid this phenomenon, different gamma adjustment standards are adopted for the first display area 1 and the second display area 2.
The first gamma adjustment criterion and the second gamma adjustment criterion are two different configuration relations of gray scale value and output data line voltage. Specifically, when the first direction y is away from the driving chip 505 of the display panel 100, the voltage of the first gamma adjustment standard configuration is lower than the voltage of the second gamma adjustment standard configuration at the same gray level.
It should be further noted that the first gamma adjustment criterion and the second gamma adjustment criterion are stored in different storage locations, and the execution subject obtains the corresponding gamma adjustment criterion by accessing the specified storage location. For example, a first gamma adjustment criterion is stored in a first storage location, a second gamma adjustment criterion is stored in a second storage location, and the execution subject accesses the first storage location to obtain the first gamma adjustment criterion from the first storage location; the execution principal obtains a second gamma adjustment criterion from a second storage location by accessing the second storage location.
S103, configuring the voltage of the first display area 1 through the data line according to the display information and the first gamma adjustment standard.
Specifically, the execution main body obtains a digital voltage according to the display information and the gamma adjustment standard, and the execution main body further needs to convert the obtained digital voltage into an analog voltage and then allocate the analog voltage to the corresponding display area.
Taking the implementation process of step 103 as an example, the process of executing the main body to adjust the standard configuration voltage according to the display information and the gamma will be specifically described.
Firstly, the execution main body acquires the digital voltage of the first display area 1 according to the display information and the first gamma adjustment standard; secondly, converting the digital voltage into an analog voltage; thus, the analog voltage is transmitted to the first display region 1 through the data line.
And S104, configuring the voltage of the second display area 2 through the data line according to the display information and the second gamma adjusting standard.
It should be noted that the implementation process of step S104 is the same as the process of step S103, and is not described herein again.
According to the display screen voltage configuration method provided by the embodiment of the invention, in a split-screen display mode, a voltage for display is configured for a first display area according to acquired display information and a first gamma adjustment standard; and configuring the voltage for displaying in the second display area according to the acquired display information and a second gamma adjusting standard. Because the distance between the driving chip and the first display area is different from the distance between the driving chip and the second display area, the length of the data line required for connecting the driving chip and the first display area is different from the length of the data line required for connecting the driving chip and the second display area, the lengths of the data lines are different, the line impedances are also different, and the generated line losses are also different. In order to relieve the influence of the line impedance of the data line on the display panel, different gamma adjustment standards are adopted to configure voltages for different display areas so as to realize compensation of different degrees of line loss of the different display areas, and therefore when the driving chip outputs the voltages to the different display areas through the data line, the voltages finally acquired by the different areas can have a uniform corresponding relation with the gray scale values of the display pictures, and the problem that the display brightness of the different display areas of the display screen is uneven in the split-screen display mode is effectively solved.
Further, the driving chip 505 can provide a voltage for driving display for one display area of the display panel 100 at a time, so that in order to enable the executing entity to accurately determine whether the first gamma adjustment criterion needs to be acquired to configure the voltage for the first display area 1 or the second gamma adjustment criterion needs to be acquired to configure the voltage for the second display area 2, so as to accurately configure the voltage for each display area, the embodiment of the present invention provides another implementation manner, a flowchart of which is shown in fig. 3, before the step S102 of acquiring the first gamma adjustment criterion and the second gamma adjustment criterion, the method further includes:
and S105, acquiring a selection signal of a gamma adjusting standard, and judging the signal type of the selection signal.
Wherein the selection signal is a periodic pulse signal, each pulse period comprising the first signal and the second signal.
Specifically, the driving chip 505 provides a working voltage for the first display region 1 during the duration of the first signal; the driving plate 505 supplies an operating voltage to the second display region 2 for the duration of the second signal.
As shown in fig. 4, taking a display panel with a resolution of 1440 × 2880 as an example, when entering the split-screen display mode, the timing relationship between the selection signal and the scan line of the display panel is specifically described. Firstly, suppose that the display panel includes 2880 scan lines, the scan lines are S1 to S2880 in sequence along the first direction y, wherein the scan lines connected to the first display region 1 are S1 to S1440, the scan lines connected to the second display region 2 are S1441 to S2880, and when the scan lines output a high level signal, the display device in the display panel can be triggered to start up, so that the voltage output from the driving chip 505 to the data lines is transmitted to the display device in the display panel through the data lines, and the display device displays a corresponding picture; during the scanning time when the scanning lines S1 to S1440 output the high-level signal to the first display area 1 in sequence, the selection signal C is the first signal (e.g., the low-level signal), thereby triggering the driving chip 505 to provide the operating voltage for the first display area 1 according to the first gamma adjustment criterion; during the scanning time when the scan lines S1441 to S2880 sequentially output the high level signal to the second display area 2, the selection signal C is a second signal (e.g., a high level signal), thereby triggering the driving chip 505 to provide the operating voltage to the second display area 2 according to the second gamma adjustment criterion.
In order to realize the operation of determining whether the first gamma adjustment standard needs to be acquired to configure the voltage for the first display area 1 or the second gamma adjustment standard needs to be acquired to configure the voltage for the second display area 2 by using the selection signal C, the present invention further provides a circuit structure, the structure diagram of which is shown in fig. 5, the circuit structure comprises a first storage module 501 for storing the first gamma adjustment standard, a second storage module 502 for storing the second gamma adjustment standard, an N-type switch tube 503 and a P-type switch tube 504, and a driving chip 505, wherein the control ends of the N-type switch tube 503 and the P-type switch tube 504 are connected with the selection signal C output module 506, the first end of the N-type switch tube 503 is connected with the display information storage module 507, and the second end of the N-type switch tube 503 is connected with the first storage module 501; the first end of the P-type switch tube 504 is also connected to the display information storage module 507, and the second end thereof is connected to the second storage module 502; the first memory module 501 and the second memory module 502 are connected to the display panel 100 through the driver chip 505. When the selection signal C output module 506 outputs a low level, the N-type switch 503 is turned on and the P-type switch 504 is turned off, the execution main body only accesses the first storage module 501, and configures voltage for the first display area 1 through the driving chip 505 according to the display information and the first gamma adjustment standard; when the selection signal C output module 506 outputs a high level, the P-type switch 504 is turned on and the N-type switch 503 is turned off, the execution main body accesses only the second storage module 502, and configures a voltage for the second display area 2 through the driving chip 505 according to the display information and the second gamma adjustment standard.
S102, acquiring the first gamma adjustment standard and the second gamma adjustment standard comprises the following steps:
and S1021, when the selection signal is judged to be the first signal, acquiring a first gamma adjustment standard corresponding to the first signal.
And S1022, when the selection signal is judged to be the second signal, acquiring a second gamma adjustment standard corresponding to the second signal.
Further, in order to more accurately know that the display panel 100 enters the split-screen display mode and trigger the main body to perform the voltage configuration for the corresponding display area of the display panel 100, an embodiment of the present invention provides another implementation manner, a flowchart of which is shown in fig. 6, where before the display panel 100 enters the split-screen display mode, the method further includes:
and S106, identifying a display mode.
Specifically, the display panel 100 displays a display mode (e.g., a split-screen display mode, a full-screen display mode, etc.) of the terminal to the user for the user to select, when the user selects the split-screen display mode, the execution main body generates a corresponding operation instruction according to the operation of the user, the execution main body obtains the operation instruction of the user and responds to the instruction, the display mode is identified according to the operation instruction of the user, and the execution main body is triggered to start the split-screen display mode.
Further, the display mode includes a normal display mode in addition to the split-screen display mode, where the normal display mode is that the third display area 3 of the display panel 100 displays an operation interface of an application, and the third display area 3 includes the first display area 1 and the second display area 2. Based on this, the present invention provides another display panel voltage configuration method for the normal display mode, as shown in fig. 7, the method further includes:
and S107, when the display mode is identified to be normal display, entering the normal display mode, and acquiring a third gamma adjustment standard.
Wherein the third gamma adjustment criterion is a gamma adjustment criterion corresponding to a combination of the first display region 1 and the second display region 2.
It should be noted that the third gamma adjustment criterion is obtained in a manner similar to the first gamma adjustment criterion, the third gamma adjustment criterion is stored in a third storage location, and the execution main body accesses the third storage location to obtain the third gamma adjustment criterion from the third storage location.
It should be added that the gamma adjustment standard of the display panel is obtained by measuring the brightness and color coordinates of each display area of the display panel at different gray scales with an optical measuring instrument, the measuring instrument transmits the measured data to an upper computer connected to the display panel and the measuring instrument, the upper computer performs fitting processing on the measured data to obtain a fitting curve of the gamma adjustment, and corrects the measured data according to the obtained fitting curve to obtain a corresponding gamma adjustment standard, and the upper computer downloads the obtained large gamma adjustment standard to a corresponding storage location in the execution main body of the embodiment.
When the display mode includes a split-screen display mode and a normal display mode, the first gamma adjustment criterion, the second gamma adjustment criterion and the third gamma adjustment criterion acquired in the split-screen display mode in the normal display mode are obtained, that is, the optical measurement instrument and the upper computer need to perform measurement and correction for three display areas. In order to reduce the measurement time of measuring the brightness and color coordinates of different display areas of the display panel under different gray scales by an optical measurement instrument such as a display color analyzer CA-310 or a colorimeter, correct the measured brightness and color coordinates by an upper computer, and the like, and simultaneously, in order to reduce the number of required wires for measurement and transmission for obtaining the first gamma adjustment standard, the second gamma adjustment standard and the third gamma adjustment standard, the third gamma adjustment standard required in a normal display mode can be obtained through certain processing according to the obtained first gamma adjustment standard and the second gamma adjustment standard. For example, the third gamma adjustment criterion is obtained by averaging the first gamma adjustment criterion and the second gamma adjustment criterion, i.e., the third gamma adjustment criterion is the average of the first gamma adjustment criterion and the second gamma adjustment criterion.
It should be added that, in order to further save the time for measuring and correcting the brightness and color coordinates of the display area and reduce the number of traces during measurement, when the corresponding gamma adjustment standard is obtained, the central area of the corresponding display area may be measured and corrected, for example, when the first gamma adjustment standard and the second gamma adjustment standard are obtained, the first gamma adjustment standard is obtained by measuring and correcting the central area of the first display area 1, and the second gamma adjustment standard is obtained by measuring and correcting the central area of the second display area 2.
And S108, configuring the voltage of the third display area 3 through the data line according to the acquired display information and the third gamma adjustment standard.
As shown in fig. 1, the third display area 3 includes the first display area 1 and the second display area 2.
Further, as shown in fig. 8, in the display panel 100, a boundary area 4 exists between the first display area 1 and the second display area 2, where the boundary area 4 is formed by a first sub-display area 10 and a second sub-display area 20, the first sub-display area 10 is a partial display area of the first display area 1, and the second sub-display area 20 is a partial display area of the second display area 2.
When the difference between the gray scale value of the first sub-display area 10 and the gray scale value of the second sub-display area 20 is within a certain range, in the split-screen display mode, the first display area 1 and the second display area 2 adopt different gamma adjustment standards, so that a display dividing line is generated in the boundary area 4 of the first display area 1 and the second display area 2, and the display effect is poor. For example: when a white picture is displayed, a boundary line appears at the boundary of the first display area and the second display area because different gamma adjustment standards are adopted at two sides. Therefore, in order to fade the display dividing line, the embodiment of the present invention further provides two implementation manners,
the first implementation mode comprises the following steps: when the display information of the boundary area 4 meets the preset condition and enters a split-screen display mode, the method further comprises the following steps:
before describing the specific operations included in the method, it should be noted that the preset condition is that the gray scale value of the display frame of the boundary area 4 is greater than a specified threshold.
It should be noted that, since the gray scale value affects the luminance of the display screen, the larger the gray scale value is, the higher the luminance is displayed. The higher the display brightness of the boundary area 4 is, the more obvious the generated display dividing line is in the split screen mode, and when the display brightness of the boundary area 4 is lower than the designated brightness value, the less obvious the display dividing line of the boundary area 4 is in the split screen mode, so that in order to simplify the operation steps and save the operation time, when the display brightness of the display boundary area 4 is lower than the designated brightness value, no further display dividing line desalination process is needed, that is, when the display information of the boundary area 4 meets the preset condition, after entering the split screen display, the steps S102, S103 and S104 are executed, and the following steps are not needed.
In a flowchart of the first implementation manner, as shown in fig. 9, the method further includes:
and S109A, acquiring a third gamma adjustment standard.
The third gamma adjustment criterion is a gamma adjustment criterion corresponding to the combination of the first gamma adjustment criterion and the second gamma adjustment criterion, that is, the third gamma adjustment criterion is a gamma adjustment criterion between the first gamma adjustment criterion and the second gamma adjustment criterion.
S110A, configuring the voltage of the boundary area 4 through the data line according to the display information of the boundary area 4 and the third gamma adjustment standard.
Since the third gamma adjustment criterion is a gamma adjustment criterion between the first gamma adjustment criterion and the second gamma adjustment criterion, in the split screen mode, by applying the third gamma adjustment criterion to provide a voltage for display to the display devices of the first sub-display area 10 and the second sub-display area 20, the display split line generated in the boundary area 4 when the difference between the gray scale values of the first sub-display area 10 and the second sub-display area 20 is within a certain range can be effectively reduced.
In a second implementation manner, as shown in fig. 10, when the display information of the boundary area 4 meets the preset condition, and after entering the split-screen display mode, the method further includes:
the preset adjustment is the same as the preset condition in the first implementation, and therefore, the details are not repeated here.
S109B, adjusting the display information of the first sub-display area 10 according to a first adjustment manner along the first direction, and adjusting the display information of the second sub-display area 20 according to a second adjustment manner.
S103 configuring the voltage of the first display area 1 through the data line according to the display information and the first gamma adjustment criterion includes:
and S1031, configuring the voltage of the first sub-display area 10 through the data line according to the display information of the first sub-display area 10 and the first gamma adjustment standard.
S104 configuring the voltage of the second display area 2 through the data line according to the display information and the second gamma adjustment standard comprises:
and S1041, configuring the voltage of the first sub-display area 10 through the data line according to the display information of the first sub-display area 10 and a first gamma adjustment standard.
Specifically, the gray scale value of the display screen of the first sub-display area 10 is adjusted according to the first adjustment manner, so that the gray scale value of the display screen of the first sub-display area 10 is decreased; and adjusting the gray-scale value of the display picture of the second sub-display area 20 according to a second adjustment mode, so that the gray-scale value of the display picture of the second display area 2 is increased gradually, and when the voltage for displaying is provided for the first display area 1 by using the first gamma adjustment standard and the voltage for displaying is provided for the first display area 1 by using the second gamma adjustment standard, a transition of display brightness is formed in the boundary area 4. Therefore, by changing the gray-scale values of the first sub-display area 10 and the second sub-display area 20, the difference of visual display generated by a user in the boundary area 4 of the first display area 1 and the second display area 2 can be relieved by adopting different gamma adjustment standards, and the display separation line can be further faded.
Based on the method embodiment of the display screen voltage configuration method, the embodiment of the invention further provides an apparatus embodiment for realizing each step and method in the method embodiment. The device is provided with a display panel 100, the display panel 100 including a display area including a first display area 1 and a second display area 2 arranged in a first direction y, in which a data line extending in the first direction y is disposed.

a first acquiring unit 41 configured to acquire display information of the display screen.
A second obtaining unit 42, configured to obtain the first gamma adjustment criterion and the second gamma adjustment criterion.

Because the distance between the driving chip and the first display area is different from the distance between the driving chip and the second display area, the length of the data line required for connecting the driving chip and the first display area is different from the length of the data line required for connecting the driving chip and the second display area, the lengths of the data lines are different, the line impedances are also different, and the generated line losses are also different. In order to relieve the influence of the line impedance of the data line on the display panel, different gamma adjustment standards are adopted to configure voltages for different display areas so as to realize compensation of different degrees of line loss of the different display areas, and therefore when the driving chip outputs the voltages to the different display areas through the data line, the voltages finally acquired by the different areas can have a uniform corresponding relation with the gray scale values of the display pictures, and the problem that the display brightness of the different display areas of the display screen is uneven in the split-screen display mode is effectively solved.
