FIG. 1 is a flowchart illustrating a method for setting screen parameters according to an exemplary embodiment.

In step 101, screen parameters of the screen are read from the screen, the screen parameters including a screen Identification (ID) number.

In this embodiment, an Electrically Erasable Programmable Read-Only Memory (EEPROM) is disposed on the tv screen side circuit driver board and is used for storing screen parameters of the screen. And when the television is started, the mainboard reads the screen parameters of the screen from the EEPROM.

In other embodiments, the television screen side circuit driver board is provided with an EEPROM for storing the screen parameters and the screen ID number of the screen. When the television is started, the mainboard reads the screen ID number of the screen from the EEPROM.

In step 102, consistency between the read screen ID number and the screen ID number configured in the motherboard program is checked.

In this embodiment, a default screen parameter is configured in the motherboard program before the motherboard is used with the screen for the first time. And if the mainboard is used with the screen, the parameters configured in the mainboard are the screen parameters configured last time. When the computer is started, the main board is powered on, and the main program passes through I²And the C bus (Intel-Integrated Circuit) reads the screen parameters in the screen end EEPROM, analyzes the screen parameters after reading the screen parameters in the screen end EEPROM, and collates the screen parameters with the screen ID number in the screen parameters configured in the mainboard program after analyzing the screen ID number.

It will be appreciated that the screen ID number is part of the screen parameters. And checking whether the screen ID number of the screen is consistent with the screen ID number in the screen parameters configured by the mainboard program, if so, determining that the current mainboard screen parameter configuration is correct, and displaying the television screen normally at the moment. If the parameters are inconsistent, the parameter configuration of the current main board screen is considered to be wrong, and the television screen cannot be normally displayed at the moment. And the screen ID number is checked to determine whether the screen parameters configured in the mainboard program are consistent with the screen parameters, and only the screen ID number is checked, so that the checking time is saved, and the time for automatically setting the screen parameters is shortened.

In other embodiments, the television screen side circuit driver board is provided with an EEPROM for storing the screen parameters and the screen ID number of the screen. It is understood that the screen parameters include a screen ID number. When the television is started, the mainboard only needs to read the screen ID number of the screen from the EEPROM. And checking whether the screen ID number of the screen is consistent with the screen ID number in the screen parameters configured by the mainboard program, if so, determining that the current mainboard screen parameter configuration is correct, and displaying the television screen normally at the moment. If the parameters are inconsistent, the parameter configuration of the current main board screen is considered to be wrong, and the television screen cannot be normally displayed at the moment.

It should be noted that, the consistency between the read screen ID number and the screen ID number configured in the motherboard program needs to be checked every time the motherboard is powered on, so as to prevent the situation that the screen cannot be normally displayed due to the replacement of screens of different models.

In step 103, if the screen parameters are inconsistent, a data record is newly established in the screen parameter database, and the screen parameters of the screen are stored.

In this embodiment, the television main board has a function of newly building a data record in the screen parameter database, and when the screen ID number in the screen parameter of the current screen is not consistent with the screen ID number in the screen parameter configured by the main board program, a data record is newly built in the screen parameter database to store the read screen parameter of the current screen. According to a set data format, after the read screen parameters are analyzed, the checking module checks the numerical value of the specific position of the check bit, if the value of the read screen parameters on the check bit is the same as the set value, the checking is successful, the analyzed screen parameters are written into the newly-created data, and if the checking is unsuccessful, the screen parameter data are obtained again and then analyzed.

In other embodiments, when the read screen ID number is not consistent with the screen ID number in the screen parameters configured by the motherboard program, the screen parameters in the EEPROM are read again, and a data record is newly established in the screen parameter database to store the read screen parameters of the current screen.

In step 104, configuring the screen parameters of the screen as the current screen parameters of the motherboard program.

And configuring the stored screen parameters of the screen as the current screen parameters of the mainboard program. So that the screen currently used cooperatively is normally displayed.

According to the technical scheme, the screen end is additionally provided with the EEPROM for storing the screen parameters, when the computer is started, the mainboard reads the screen parameters stored in the EEPROM of the screen end, analyzes the screen ID number of the screen, and collates the screen ID number with the screen parameters configured in the mainboard program. If the parameters are consistent, the configuration of the screen parameters of the main board is considered to be correct, the television screen is normally displayed, if the parameters are not consistent, the main board creates a data record, records the screen parameters of the screen, configures the screen parameters as the current screen parameters of the main board program,

so that the television screen displays normally. The process of setting screen parameters is automatically completed, and developers are not required to participate in a new program for upgrading the mainboard, so that the screen parameters can be normally displayed.

FIG. 2 is a flowchart illustrating a method for setting screen parameters according to an exemplary embodiment.

In step 101, screen parameters of the screen are read from a screen storage module, wherein the screen parameters comprise a screen ID number.

In this embodiment, an EEPROM is provided in the tv screen side circuit driver board, and is used to store screen parameters of the screen. In this embodiment, the screen parameters of the television screen are stored in the EEPROM memory according to a set information format (i.e., a protocol), and the main board also analyzes the read screen parameter data according to the same information format.

In this embodiment, the Data that the television motherboard needs to confirm the screen parameters only includes several Data such as the screen ID number, the line number in one field of the screen, the vertical resolution, and the like, and information represented in many bytes in the Extended Display Identification Data (EDID) Data standard, which is not needed to be confirmed by the television motherboard. Table 1 is a two-dimensional (2D) display screen portion screen parameter specification. The screen parameters of the television screen are stored in the EEPROM memory according to a set information format, which is illustrated in table 2 by taking a two-dimensional (2D) display screen specification as an example.

TABLE 1

TABLE 2

The following describes the information format in detail:

byte 1, 8 bits (bit), represents a start bit, for example: 01010101 (or other special value). If the start bit is not judged well, the bytes can be added, and the rest bytes are delayed in sequence. When the motherboard obtains this data, it indicates that screen parameter data starts to be received, and parses the screen parameter data according to the information format, for example: when the byte data of this start flag is received according to the information format, the 11 th and 12 th byte data values received thereafter represent the vertical resolution (i.e., tdisp (v)) in the screen parameter.

Bytes 2, 3 and 4 represent the screen ID number of the screen.

Where byte 2, 8 bits, the first 5 bits represent the size of the screen, from 00000 to 11111 are data 0 to 31, for a total of 32 groups of data, each representing a different size. For example, make (illustrated in decimal): 0-24 cun; 1-32 cun; 2-39 cun; 3-40 cun; 4-43 cun; 5-49 cun; 6-50 cun; 7-55 cun; 8-60 cun; 9-65 cun; 10-65 cun; 11-75 cun; 12-80 cun; 13-100 cun; 14-N1 cun; ...; 31-N cun. The current television size classification is sufficient to be distinguished by 32 groups of data, and the current television display screen has about 20 sizes. The last 3 bits and 3 and 4 bytes represent the screen number, i.e., each size screen can be divided into 8 × 256 (i.e., 524288) models.

It should be noted that each type of screen corresponds to the same screen ID number, and not each screen has a different screen ID number. The motherboard is calibrated to the screen parameters configured in the motherboard program based on the screen ID number (i.e., bytes 2, 3, and 4 of data).

Bytes 5 through 10 represent the number of lines in one field of the screen (i.e., Tv) in the screen parameter. As shown in table 3, the three groups of values of 5 th, 6 th, 7 th, 8 th, 9 th, 10 th byte represent the minimum value, the typical value and the maximum value of TV in the screen specification.

Optionally, the verification process may be to perform bit-by-bit verification on the data, and when a value on a transmitted screen parameter verification bit is different from a set value, it is determined that the data transmission is incorrect.

Similarly, 16 bits are contained in the 7 th byte and the 8 th byte, the first 13 bits represent values from 0 to 8160, the fixed value of the last 3 bits is 010, the set of values represent typical values and are check bits, and if the last 3 bits of the 8 th byte read by the mainboard are not 010, the whole data transmission is wrong.

Similarly, 16 bits are shared by the 9 th byte and the 10 th byte, the first 13 bits represent values from 0 to 8160, the last 3 bits fix a value of 100, the value represents the maximum value of the group of values, and the values are check bits, if the last 3 bits of the 10 th byte read by the mainboard are not 100, the whole data transmission is wrong.

Bytes 11 and 12 represent the effective display line number, also known as the vertical resolution (i.e., tdisp (v)). The value is determined from the specification to be a fixed value, and the minimum value, the typical value and the maximum value are the same. As shown in table 3, the total of 16 bits, the first 13 bits represent values 0 to 8160, the last 3 bits fix values 000, the 3 bits are all 0, the group of values represent the minimum value, the typical value and the maximum value are all the same, and the values are check bits, if the last 3 bits of the 12 th byte read by the main program is not 000, the whole data transmission is incorrect.

TABLE 4

The 13 th, 14 th, 15 th, 16 th, 17 th, 18 th byte, three groups of values respectively represent the minimum value, typical value and maximum value of the vertical blanking (i.e. tblk (v)) in the screen specification. The same Tv part is specifically defined.

The three groups of values of 19 Th byte, 20 Th byte, 21 Th byte, 22 Th byte, 23 Th byte and 24 Th byte represent the minimum value, the typical value and the maximum value of the column number (namely Th) in one field of the screen in the screen specification. The same Tv part is specifically defined.

Bytes 25 and 26 represent the number of active display columns, also known as horizontal resolution (i.e., tdisp (h)). The value is determined from the specification to be a fixed value, and the minimum value, the typical value and the maximum value are the same. The same Tv part is specifically defined.

The 27 th, 28 th, 29 th, 30 th, 31 th, 32 th byte, three groups of values respectively represent the minimum value, typical value and maximum value of the horizontal blanking (i.e. tblk (h)) in the screen specification. The same Tv part is specifically defined.

The 33 rd, 34 th, 35 th, 36 th, 37 th, 38 th byte, three groups of values respectively represent the minimum value, the typical value and the maximum value of the main clock frequency (i.e. Fclk is 1/Tclk) in the screen specification. The same Tv part is specifically defined.

Bytes 39, 40, 41, 42, 43, 44, three sets of values respectively represent the minimum, typical and maximum values of the vertical refresh rate (Fv) in the screen specification. The same Tv part is specifically defined.

After the 50 th byte, screen parameter data of a three-dimensional (3D) display part, specifically, contents of a referenceable 2D part, can be defined.

The nth byte, the N +1 th byte can be used as an end mark to finish the data transmission of the screen parameter.

In step 203, if not, screen parameters of the screen are queried in a screen parameters database.

In this embodiment, the main board storage module may store screen parameters of dozens of commonly used screens when the main board storage module leaves a factory. And when the screen ID number in the screen parameters configured by the mainboard program is inconsistent with the screen ID number of the current screen. The main board inquires whether screen parameters identical to the screen ID number of the current screen exist in the screen parameter database. When inquiring the screen parameter database, inquiring the screen parameters in the screen parameter database according to the screen ID number.

In step 204, after the screen parameter of the screen is queried, the screen parameter of the screen is configured to be the current screen parameter of the motherboard program.

In this embodiment, the motherboard queries the screen parameter that is the same as the current screen ID number in the motherboard program screen parameter database, configures the screen parameter that is the same as the current screen ID number as the current screen parameter of the motherboard program, and if the screen parameter that is the same as the current screen ID number is not queried, considers that the motherboard and the screen are used in cooperation for the first time, and at this time, the motherboard program may newly establish a data record in the screen parameter database, store the screen parameter of the screen, and configure the screen parameter of the screen as the current screen parameter of the motherboard program.

According to the technical scheme, the mainboard program and the screen are communicated according to the set information format, and the mainboard storage module can store screen parameters of dozens of common screens when leaving a factory, so that when the mainboard is matched with different screens for use, if the screen parameters of the screen exist in the screen parameter database, a new screen parameter data record is not needed, and the time for setting the screen parameters is saved. And if the screen parameters of the screen do not exist in the screen parameter database, a screen parameter data record is newly established, and the screen parameters of the screen can be directly configured for normal display when the screen parameter data record is matched with the same screen or the screen with the same model for use next time.
