[0002] With the rapid development of embedded technology, embedded devices are also continuously applied to people's lives, thus facilitating people's lives. Display screens are also applied to various embedded devices. In the interaction between embedded devices and users, the display screen is an indispensable part.

[0085] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0086] In the related art, the controller of the display screen controls the on or off of the display screen code segment by directly writing display data to the register. This method is difficult to ensure real-time communication with the display screen, and it is easy to cause a stuck screen or incomplete display. In order to solve the above technical problems, the present invention provides a display control method for a display screen, first obtaining the number of common electrodes of the display screen, when the number of common electrodes is less than or equal to the preset number, configuring the buffer and display area in the register of the display screen according to the number of common electrodes, wherein the number of bits in the buffer and the number of bits in the display area correspond to the number of common electrodes, when the first display data to be displayed is obtained, the first display data is written into the buffer, thereby playing a buffering role for the first display data, and then the first display data in the buffer is synchronized to the display area, and finally the first display data in the display area is displayed, so that when the number of common electrodes of the display screen is less than or equal to the preset number, the register of the display screen is configured, the buffer and the display area are configured, and the first display data is buffered and the data is synchronized through the setting of the buffer and the display area, thereby ensuring the integrity of the display data and avoiding the stuck screen phenomenon of the display screen.

[0087] Reference Figure 1 , shows a flowchart of a display control method for a display screen provided by an embodiment of the present invention, and the method may specifically include the following steps:

[0088] Step 101, obtaining the number of common electrodes of the display screen.

[0089] In an embodiment of the present invention, the display screen may be a liquid crystal display screen, a controller may be provided in the display screen, a control chip and a register may be deployed in the controller, and the register may be a SEGCOM_x register. When the controller controls the display of the liquid crystal display, it can generally write display data into the register to control the code segment control bit of the corresponding register. For example, when it is necessary to light up the code segment on the display screen, the code segment control bit of the corresponding register can be set to 1, and when it is necessary to extinguish the code segment on the display screen, the code segment control bit of the corresponding register can be set to 0.

[0090] In the present invention, the controller can control the liquid crystal display of different COM*SEG segments, the COM segment is a common segment, the SEF segment is a segment, the controller generally has a total of 32 segments, a maximum of 8 common segments can be supported, and a minimum of 1 common segment can be supported. The segments other than the common segments can be segments. For example, the controller can support the following specifications of liquid crystal display segments (COM*SEG): 1*31, 2*30, 3*29, 4*28, 5*27, 6*26, 7*25, 8*24.

[0091] like Figure 2 As shown, a schematic diagram of the display control principle of a display screen provided by an embodiment of the present invention is shown. Display screens of different specifications have different numbers of COM*SEG. For example, a 4*28 display screen requires 4 COMs and 28 SEGs to drive the display screen. Two COMs and 28 SEGs constitute a coordinate system. By lighting up the code segments corresponding to the coordinates, the display screen can be controlled. Figure 2 COM0-COM7 in the diagram can be equivalent to x in the rectangular coordinate system, and SEG0-SEG31 can be equivalent to y in the rectangular coordinate system. In the coordinate system, one coordinate corresponds to one point. In the controller, the coordinate corresponds to one code segment. If you need to light up the code segment, you need to obtain the coordinate of the code segment and then set it to 1. If you need to turn off the code segment, you need to obtain the coordinate of the code segment and then set it to 0.

[0092] In the present invention, the register can be composed of 4 bytes, one byte can represent a SEG segment, one byte has 8 bits, and 1 bit can represent a COM segment. The register can convert the coordinates into bits, and the process of controlling the bits of the register is also the process of controlling the code segment. When controlling display screens of different specifications, the corresponding display data can be written into the bit of the corresponding COM segment according to the number of COM segments of the display screen, that is, the common electrodes of the display screen.

[0093] In the embodiment of the present invention, when performing display control on the display screen, the controller may first obtain the number of common electrodes of the display screen, that is, the controller may obtain the number of COM segments required to control the display screen.

[0094] Step 102, when the number of the common electrodes is less than or equal to a preset number, configuring a buffer area and a display area in a register of the display screen according to the number of the common electrodes; the number of bits in the buffer area and the number of bits in the display area correspond to the number of the common electrodes.

[0095] In an embodiment of the present invention, after obtaining the number of common electrodes of the display screen, it can be determined whether the number of common electrodes is less than or equal to a preset number. In the present invention, the preset number can be half of the binary digits of the register, for example, the preset number is 4. When the common electrodes of the display screen are less than or equal to 4, the register of the display screen can be configured according to the number of common electrodes, and a buffer area and a display area can be configured in the register. Among them, the number of bits of the buffer and the number of bits of the display area can correspond to the number of common electrodes, for example: if the number of common electrodes is 4, then the number of bits of the buffer and the number of bits of the display area are also 4, and if the number of common electrodes is 2, then the number of bits of the buffer and the number of bits of the display area are also 2.

[0096] In one embodiment, a buffer area and a display area in a register of a display screen are configured according to the number of common electrodes, including: determining the number of display bits and the number of buffer bits of a register of the display screen according to the number of common electrodes; configuring the display area of ​​the register according to the number of display bits; and configuring the buffer area of ​​the register according to the number of buffer bits and the display area.

[0097] For example: when the number of common electrodes of the display screen is 4, that is, COM is 4, then it can be determined that the number of display bits of the register of the display screen is 4, and the number of buffer bits is 4. According to the number of display bits, the display area of ​​the register is configured as BIT0-3, and according to the number of buffer bits and the display area, the buffer area of ​​the register is configured as BIT4-7. Another example: when the number of common electrodes of the display screen is 2, that is, COM is 2, then it can be determined that the number of display bits of the register of the display screen is 2, and the number of buffer bits is 2. According to the number of display bits, the display area of ​​the register is configured as BIT0-1, and according to the number of buffer bits and the display area, the buffer area of ​​the register is configured as BIT2-3, then BIT4-7 of the register is an invalid BIT bit, and when data is written to the invalid BIT bit, it has no effect on the LCD display.

[0098] Step 103: When first display data to be displayed is acquired, the first display data is written into the buffer.

[0099] In the embodiment of the present invention, after the buffer area and the display area in the register of the display screen are configured, when the first display data to be displayed is acquired, the first display data can be written into the buffer area.

[0100] In one embodiment, when the first display data to be displayed is obtained, the first display data is written into a buffer, including: when the first display data to be displayed is obtained, determining whether the state of the register is a write-protected state; when the state of the register is not a write-protected state, writing the first display data into the buffer and setting the state of the register to a write-protected state.

[0101] Specifically, when the first display data to be displayed is obtained, it can be determined first whether the state of the register is a write-protected state. When the state of the register is a write-protected state, it can indicate that the first display data cannot be written into the buffer of the register. When the state of the register is not a write-protected state, it can indicate that the first display data can be written into the buffer of the register. At this time, the first display data is written into the buffer, and then the state of the register is set to a write-protected state, so that when the first display data in the buffer has not yet been synchronized to the display area, new display data is written into the buffer, thereby avoiding incomplete or abnormal first display data.

[0102] In one embodiment, when the first display data to be displayed is obtained, determining whether the state of the register is a write-protected state may include: when the first display data to be displayed is obtained, obtaining a state value corresponding to the state of the register; when the state value is a first preset value, determining that the state of the register is a write-protected state; when the state value is a second preset value, determining that the state of the register is not a write-protected state.

[0103] For example, the first preset value is 1, and the second preset value is 0. When the first display data to be displayed is obtained, the status value corresponding to the status of the register can be obtained. When the status value is 1, it can be determined that the status of the register is a write-protected state. When the status value is 0, it can be determined that the status of the register is not a write-protected state.

[0104] In one embodiment, when the state of the register is not a write-protected state, writing the first display data into the buffer and setting the state of the register to a write-protected state may include: when the state of the register is not a write-protected state, writing the first display data into the buffer and modifying the state value to a first preset value.

[0105] For example, when the state value corresponding to the state of the register is 0, it is determined that the state of the register is not in a write-protected state, and the first display data can be written into the buffer, and then the state value corresponding to the state of the register is modified to 1. In other words, when the state of the register is in a write-protected state, it indicates that there is display data in the buffer of the register, and when the state of the register is not in a write-protected state, it indicates that there is no display data in the buffer of the register.

[0106] Step 104: synchronize the first display data in the buffer to the display area.

[0107] In the embodiment of the present invention, after the first display data is written into the buffer area of ​​the register, the first display data in the buffer area may be synchronized to the display area in the register.

[0108] In one embodiment, synchronizing the first display data in the buffer to the display area may include: when the state of the register is a write protection state, synchronizing the first display data in the buffer to the display area and canceling the write protection state of the register.

[0109] Specifically, when the state of the register is a write-protected state, it indicates that there is display data in the buffer of the register. Then the first display data in the buffer can be synchronized to the display area, and then the state value corresponding to the register state is modified to 0, and the write-protected state of the register is canceled, so that the register is not in a write-protected state, and display data can continue to be written to the buffer of the register.

[0110] Step 105: display the first display data in the display area.

[0111] In the embodiment of the present invention, after the first display data in the buffer area is synchronized to the display area, the first display data in the display area can be displayed through the display screen.

[0112] In an embodiment of the present invention, after the first display data in the display area is displayed, it also includes: when a control instruction is obtained, determining whether the control instruction is to disable the display screen; when the control instruction is to disable the display screen, disabling the display screen; when the control instruction is not to disable the display screen, determining whether the state of the register is a write-protected state; when the state of the register is not a write-protected state, writing the second display data in the control instruction into the buffer of the register, and setting the state of the register to a write-protected state; when the state of the register is a write-protected state, synchronizing the second display data in the buffer of the register to the display area of ​​the register, and canceling the write-protected state of the register; and displaying the second display data in the display area.

[0113] Specifically, when the display of the display screen needs to be controlled again, for example, when the display data needs to be modified, that is, when the displayed content needs to be modified, or when the display screen needs to be disabled, a control instruction can be sent to the controller. When the controller obtains the control instruction, it can first determine whether the control instruction is to disable the display screen. When the control instruction is to disable the display screen, the control instruction can be responded to and the display screen can be disabled. When the control instruction is not a display screen, the control instruction generally carries a second display data, and the second display data can be display data modified for the first display data. At this time, it can be determined whether the state of the register is a write-protected state. When the state of the register is not a write-protected state, the second display data can be written into the buffer of the register, and the state of the register is set to a write-protected state, and then it is determined whether the state of the register is a write-protected state. When the state of the register is a write-protected state, the second display data in the buffer of the register can be synchronized to the display area of ​​the register, and the write-protected state of the register can be canceled, and finally the second display data in the display area is displayed.

[0114] In an embodiment of the present invention, the display control method of a display screen may further include: when the number of common electrodes is greater than a preset number, writing first display data into a register; and displaying the first display data in the register.

[0115] For example, the preset number is 4, and the number of common electrodes of the display screen obtained is 5. At this time, the number of common electrodes is greater than the preset number. At this time, there is no need to configure the buffer area and display area of ​​the register. The first display data can be directly written into the register, and then the first display data in the register can be displayed.

[0116] In an embodiment of the present invention, after displaying the first display data in the register, it also includes: when a control instruction is obtained, determining whether the control instruction is to disable the display screen; when the control instruction is to disable the display screen, disabling the display screen; when the control instruction is not to disable the display screen, writing the second display data in the control instruction into the register; and displaying the second display data in the register.

[0117] Specifically, when the display of the display screen needs to be controlled again, for example, when the display data needs to be modified, that is, when the displayed content needs to be modified, or when the display screen needs to be disabled, a control instruction can be sent to the controller. When the controller obtains the control instruction, it can first determine whether the control instruction is to disable the display screen. When the control instruction is to disable the display screen, the control instruction can be responded to and the display screen can be disabled. When the control instruction is not a display screen, the control instruction generally carries the second display data, which can be the display data modified for the first display data. At this time, the second display data can be directly written into the register, and then the second display data in the register can be displayed.

[0118] In order to better understand the specific content of the embodiments of the present invention, Figure 3 The embodiments of the present invention are described in detail. Figure 3 As shown, a step flow chart of a display control method for another display screen provided by an embodiment of the present invention is shown. First, the number of common electrodes of the display screen is obtained, and it is determined whether the data of the common electrodes is less than or equal to 4. When the number of common electrodes is greater than 4, the first display data to be displayed is written into the register, and the first display data in the register is displayed. When a control instruction is obtained, it is determined whether the control instruction is to disable the display screen. When the control instruction is to disable the display screen, the display screen is disabled. When the control instruction is not to disable the display screen, the second display data in the control instruction is written into the register, and the second display data in the register is displayed.

[0119] When the number of common electrodes is less than or equal to 4, the buffer and display area in the register of the display screen are configured according to the number of common electrodes, and it is determined whether the status value of the register is 1. When the status value of the register is 1, it is continued to be determined whether the status value of the register is 1. When the status value of the register is not 1, that is, when the status value of the register is 0, the first display data with display is written into the buffer, and then it is determined whether the status value of the register is 1. When the status value of the register is not 1, that is, when the status value of the register is 0, it is continued to be determined whether the status value of the register is 1. When the status value of the register is 1, the first display data in the buffer is synchronized to the display area, and the status value of the register is modified to 0, and then the first display data in the display area is displayed.

[0120] When a control instruction is obtained, determine whether the control instruction is to disable the display screen. When the control instruction is to disable the display screen, the display screen is disabled. When the control instruction is not to disable the display screen, determine whether the status value of the register is 1. When the status value of the register is 1, continue to determine whether the status value of the register is 1. When the status value of the register is not 1, that is, when the status value of the register is 0, write the second display data in the control instruction to the buffer, and then determine whether the status value of the register is 1.
