Detailed Description

For the purposes of making the objects, embodiments and advantages of the present application more apparent, an exemplary embodiment of the present application will be described more fully hereinafter with reference to the accompanying drawings in which exemplary embodiments of the application are shown, it being understood that the exemplary embodiments described are merely some, but not all, of the examples of the application.

It should be noted that the brief description of the terminology in the present application is for the purpose of facilitating understanding of the embodiments described below only and is not intended to limit the embodiments of the present application. Unless otherwise indicated, these terms should be construed in their ordinary and customary meaning.

Furthermore, the terms "comprise" and "have," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a product or apparatus that comprises a list of elements is not necessarily limited to those elements expressly listed, but may include other elements not expressly listed or inherent to such product or apparatus.

Fig. 1 is a schematic view of a structure of a display device in the related art. As shown in fig. 1, the display device may include a System on Chip (SoC), a timing control (timing controller, TCON) circuit board (abbreviated as TCON board), and a display screen. Currently, TCON boards of most display devices (for example, smart televisions) are built-in TCON boards, that is, functions that can be implemented by a special TCON chip of the TCON board are integrated in a main board SoC, and the functions that can be implemented by the TCON chip are implemented by the main board SoC.

In this implementation, the voltage management components of the TCON board are retained on the TCON board, such as a power management unit (Power Management Unit, PMU), a Gamma voltage management unit (Gamma integrated circuit, gamma IC), a timing signal Level conversion unit (Level-shift integrated circuit, level-shift IC) as shown in fig. 1.

In the related art, after the display device is powered on, each voltage management component on the TCON board needs to be initialized first. Specifically, a manner for initializing each voltage management component on the TCON board and initialization data to be written into each voltage management component on the TCON board may be set in the SoC of the main board of the display apparatus. After the display device is powered on, the codes corresponding to the mode are operated so as to write the initialization data of each voltage management component into the corresponding voltage management component, and the initialization of each voltage management component is realized.

Then, the display device can control each voltage management component to provide voltage for the display screen, so that the display screen can display images. For example, the display device may control the PMU to provide a supply voltage for the display screen, adjust the voltage output by the Gamma IC to the display screen to achieve the effect of adjusting the brightness of the display screen, output a timing signal required by the display screen to the Level-shift IC, and control the Level-shift IC to perform Level conversion on the timing signal and output the Level-shift signal to the display screen.

However, there are various types of PMUs, gamma ICs, and Level-shift ICs, and there are situations where the voltage management components on the TCON board need to be replaced. For example, in the case of chip resource shortage, it is necessary to replace the voltage management component of chip resource shortage on the TCON board with the voltage management component of chip resource sufficiency. Alternatively, if the voltage management component on the TCON board fails, the voltage management component that is functional needs to be replaced with a voltage management component that is functional.

In the existing TCON board initialization method, if the voltage management components on the TCON board are replaced, since different initialization programs, initialization data and the like are required for the voltage management components of different models, the SoC needs to be redeveloped, so that the SoC can initialize the replaced voltage management components on the TCON board. However, the SoC is usually redeveloped, so that a different complete machine model is required to be derived, and the period of redeveloped verification of the SoC can reach at least 2-3 months. Therefore, the existing TCON board initialization method has a problem of causing a low development efficiency of the display apparatus.

Considering that the above-mentioned problems exist in the conventional TCON board initialization method because the SoC needs to be redeveloped when the voltage management components of different models are replaced on the TCON board, the present application provides a method that does not need to redevelop the SoC even if the voltage management components of different models are replaced on the TCON board, so as to improve the development efficiency of the display device.

Fig. 2 is a schematic structural diagram of a display device according to the present application. As shown in fig. 2, the display device provided by the present application may include a display screen, a TCON board, and a processor. The TCON plate may include: a storage component, and at least one voltage management component. The processor is connected with the first end of the TCON board, and the second end of the TCON board is connected with the display screen.

Alternatively, the processor may be integrated on a motherboard SoC of a display device as described above, for example. The processor may be implemented, for example, in hardware in at least one of digital signal processing (Digital Signal Processing, DSP), field programmable gate array (Field-Programmable Gate Array, FPGA), programmable logic array (Programmable Logic Array, PLA). The processor may integrate one or a combination of several of a central processing unit (Central Processing Unit, CPU), an image processor (Graphics Processing Unit, GPU), and a modem etc.

The storage component on the TCON board may store a model identifier of the at least one voltage management component. The memory component may be, for example, a type of read-only memory such as a charged erasable programmable read-only memory (Electrically Erasable Programmable read only memory, EEPROM), flash memory, or the like. Alternatively, the memory component on the TCON board may be an EEPROM (smaller in size) to reduce the space occupied by the TCON board. Taking a storage component as an EEPROM as an example, the display device passes through I ² C (a serial communication bus name) reads the model identification of the at least one voltage management component from the EEPROM. In some embodiments, taking the storage component on the TCON board as a Flash memory, the display device may read the model identifier of the at least one voltage management component from the Flash memory of the TCON board through a serial peripheral interface (Serial Peripheral Interface, SPI).

In some embodiments, the voltage management component may include, for example, any of the following: PMU, gamma IC, and Level-shift IC.

In some embodiments, the display screen may include a display panel. The display panel may employ a liquid crystal display (liquid crystal display, LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode (AMOLED) or an active-matrix organic light-emitting diode (matrix organic light emitting diode), a flexible light-emitting diode (fle×light-emitting diode, FLED), a mini, a Micro led, a Micro-OLED, a quantum dot light-emitting diode (quantum dot light emitting diodes, QLED), or the like. In some embodiments, the display device may include 1 or more display screens.

It should be understood that the display device provided by the application can be, for example, a display device such as a smart television, a smart interactive tablet and the like.

Further, it should be understood that fig. 2 is merely an exemplary illustration taking the relevant structure of the display device according to the present application as an example. The application is not limited as to whether the display device further comprises other components and whether the TCON board further comprises other components. For example, taking the display device as an example, the display device may further include components such as a speaker, and the like, which are not described herein. For example, as shown in fig. 1, the display device may further control the main board SoC to transmit a P2P (Point to Point) signal including the image display content to the display screen through the TCON board, so that the display screen may perform image display.

The method for initializing the TCON board provided by the application is described in detail below with reference to specific embodiments. The following embodiments may be combined with each other, and some embodiments may not be repeated for the same or similar concepts or processes.

Fig. 3 is a schematic flow chart of a TCON board initialization method provided by the present application. As shown in fig. 3, the method comprises the steps of:

s101, for any voltage management component in at least one voltage management component, reading the model identification of the voltage management component from a storage component.

Taking the example of a storage component having stored therein model identifiers of a plurality of voltage management components, the display device may, for example, read the model identifiers of one voltage management component at a time from the storage component. For example, the display device may read the model identification of each voltage management component from the storage component in order of storage of the plurality of model identifications in the storage component.

Alternatively, the model identifier may be a model code for each voltage management component. Or, the display device may further read a byte corresponding to the model identifier from the storage component, and then determine the model identifier of the voltage management component according to a mapping relationship between the byte and the model identifier. The mapping relationship between the bytes and the model identifier may be stored in the display device in advance for the user, for example.

S102, determining an initialization program for initializing the voltage management component according to the model identification of the voltage management component.

Alternatively, the initialization program may be a piece of code, or may be a packaged program.

In some embodiments, the display device may determine an initialization procedure for initializing the voltage management component, for example, after obtaining the model identification of the voltage management component, based on the model identification of the voltage management component, and a mapping relationship between the model identification and the initialization procedure. The mapping relationship between the model identifier and the initialization program may be shown in the following table 1, for example:

TABLE 1

Model identification	Initialization program
		Sign 1	Mode 1
Sign 2	Mode 2
		Sign 3	Mode 3
…	…

Assuming that the display device determines that the model identification of the voltage management component is identification 2, the display device may determine an initialization procedure for initializing the voltage management component as mode 2 according to the mapping relationship shown in table 1.

In some embodiments, the mapping between the model identification and the initialization program may be pre-stored in the memory of the display device. The memory of the display device and the aforementioned processor may be both integrated in a motherboard SoC of the display device.

S103, running the initialization program to initialize the voltage management component.

After determining an initialization procedure for initializing the voltage management component, the display device may run the initialization procedure through the processor to initialize the voltage management component. The initialization process may include, for example, writing initialization data corresponding to the voltage management component into a register of the voltage management component.

With reference to the foregoing method, after the initialization operation is completed for each voltage management component on the TCON board, the display device may control each voltage management component on the TCON board to provide the voltage required for image display for the display screen, so as to improve the stability of image display performed by the display screen, and ensure the operation safety of the display device. Optionally, the specific implementation manner of the display device to control each voltage management component on the TCON board to provide the voltage required for displaying the image for the display screen may refer to the existing implementation manner, and the disclosure is not repeated herein.

It should be understood that the display device may initialize each voltage management component on the TCON board one by one, or may initialize each voltage management component on the TCON board at the same time, which is not limited by the present application.

In this embodiment, by reading the model identifier of the voltage management component on the TCON board stored in the storage component on the TCON board, an initialization program required for initializing the voltage management component may be determined according to the model identifier. By running the initialization program, the voltage management component may be initialized. By the method, when the TCON board is replaced, the display equipment only needs to read the model identification of the voltage management component on the replaced TCON board from the storage component of the replaced TCON board, and then the replaced voltage management component can be initialized. By the method, when the TCON plate is replaced, the display equipment does not need to be developed again, and the development efficiency of the display equipment is improved.

As previously mentioned, the display device may initialize the voltage management component by running an initialization program. In some embodiments, the initialization parameters corresponding to different voltage management components may be different, and the display device may initialize the voltage management components by inputting the initialization parameters corresponding to the voltage management components into an initialization program and then running the initialization program.

Wherein, in some embodiments, the initialization parameters may include at least one of: the address of the register of the voltage management component, the initialization data to be written into the register of the voltage management component, the interface identification required for writing the initialization data into the register of the voltage management component, and the like. To display the pass I between the processor and the TCON board in the equipment ² C (name of serial communication bus) for example, the interface identifier required for writing initialization data to the register of the voltage management component may be, for example, I required for communication between the processor and the register of the voltage management component on the TCON board ² C, interface identification.

As a possible implementation manner, the initialization parameters corresponding to each voltage management component on the TCON board may be pre-stored in the main board SoC of the display device. In this implementation manner, after the display device reads the model identifier of the voltage management component from the storage component of the TCON board, the initialization parameter corresponding to the voltage management component may be determined according to the model identifier of the voltage management component and the mapping relationship between the model identifier of the voltage management component and the initialization parameter.

As another possible implementation, the storage component of the TCON board may have stored thereon: initialization parameters for each voltage management component on the TCON board. In the following, a detailed description will be given of how the display device initializes the voltage management components, taking as an example that the storage component also stores the initialization parameters of each voltage management component. Fig. 4 is a flow chart of a method for initializing a voltage management component according to the present application. As shown in fig. 4, as a possible implementation manner, the method may include the following steps:

s201, reading initialization parameters of the voltage management component from the storage component.

In some embodiments, the display device first reads data from the storage component and then determines whether the identification of the data characterizes the data as data for the voltage management component.

If the identifier of the data represents that the data is the data of the voltage management component, the display device can analyze the initialization parameter corresponding to the voltage management component from the data. Alternatively, the display device may obtain different initialization parameters corresponding to the voltage management component by, for example, reading bytes of the target location in the data.

By way of example, examples of data stored in the storage component may be as shown in Table 2 below:

Wherein GMA represents a Gamma IC voltage management component. LS represents a Level-shift IC voltage management component. In table 2, one row of bytes in table 2 represents one data, and 0x50, 0x47, and 0x4C are all data representing that the identification of the data characterizes the data as a voltage management component. If the display device reads the data corresponding to 0x50 from the storage component, the data is indicated to be the data of the voltage management component.

Then, the display device can read the model identification of the voltage management component from the 01 st byte in the data, such as ic_index shown in table 2; reading the register to the voltage management component from the 02 nd byte in the dataThe memory writes the interface identifier required to initialize the data, i.e. as shown in table 2 ² C_addr; the address of the register of the voltage management component is read from A0-A7 in the data, and the initialization data to be written to the register of the voltage management component is read from D0-D7 in the data. As shown in table 2, the data may further include a component Number High (PNH), a component Number Low (PNL), and a Version (Version) of the EEPROM data. Wherein PNH and PNL are used to verify the matching of EEPROM data and TCON board.

If the identification of the data characterizes that the data is not data of a voltage management component, optionally, the display device may continue to read the next data in the storage component until the display device determines that there is no "data of a voltage management component that has not been read yet" in the storage component. When the display device determines that the data of the voltage management components which are not read yet exist in the storage component, the initialization of each voltage management component on the TCON board is determined to be completed, and then the display device can control the at least one voltage management component to provide voltage for the display screen so that the display screen can display images.

S202, inputting initialization parameters of the voltage management component into an initialization program.

Optionally, the display device may, for example, input different initialization parameters to corresponding positions in the initialization program, so as to ensure the accuracy of the initialization program.

S203, running the initialization program to initialize the voltage management component.

For example, the display device may run the initialization program to determine the bus interface to transfer data with the voltage management component by writing the interface identification required to initialize the data to the registers of the voltage management component. And writing initialization data to be written into the register of the voltage management component according to the address of the register of the voltage management component through the bus interface.

In this implementation, by storing the initialization parameters of the voltage management component in the memory component of the TCON board, the memory component is replaced when the TCON board is replaced. The display device can read the initialization parameters of the voltage management components in the storage components in any replaced TCON board to initialize the voltage management components on any TCON board. By the method, when the TCON plate is replaced, the display equipment does not need to be developed again, and the development efficiency of the display equipment is improved.

As another possible implementation manner, the initialization parameters include: for example, the display device may further read the initialization data of the voltage management component from the register of the voltage management component, and compare the initialization data of the voltage management component with the initialization data of the register of the voltage management component read from the storage component.

If the voltage management component determines that the existing initialization data is different from the initialization data read from the storage component and to be written into the register of the voltage management component, the initialization data read from the storage component and to be written into the register of the voltage management component is required to be used for updating the existing initialization data, so that the display device can accurately control the voltage management component to provide normal working voltage for the display screen. The display device may input the initialization data read from the storage device to be written into the register of the voltage management device into an initialization program, so that the display device may implement initialization of the voltage management device by running the initialization program, and writing the initialization data to be written into the register of the voltage management device.

In some embodiments, if the display device determines that the initialization data of the voltage management component is the same as the initialization data read from the storage component to be written to the register of the voltage management component, it indicates that the initialization data of the voltage management component is correct, and the voltage management component does not need to be initialized again. The display device may control at least one voltage management component on the TCON board to provide voltage to the display screen to cause the display screen to display images. By the method, the display equipment is prevented from initializing the voltage management assembly again, the operation calculation amount of the display equipment is reduced, and the starting efficiency of the display equipment is improved.

As yet another possible implementation manner, the display device may further determine whether to input the initialization parameter of the voltage management component into the initialization program after checking the initialization parameter of the voltage management component acquired from the storage component.

If the display device passes the verification of the initialization parameter, which indicates that the initialization parameter is correct, the display device may input the initialization parameter of the voltage management component into the initialization program.

In some embodiments, the display device may read a preset standard value from the storage component. Then, the display device may obtain a verification value of the initialization parameter through a preset verification manner. And when the verification value of the initialization parameter is the same as the preset standard value, the display equipment can determine that the verification of the initialization parameter passes.

Illustratively, taking the foregoing preset verification method as an example of calculating the Checksum of the initialization parameter, assuming that the display device may read, from the storage component, data corresponding to the data identifier 0x50 as shown in table 2, the display device may use the 03 th byte of the data, that is, the Checksum, as the preset standard value Checksum. It is assumed that the display device obtains the check value of the initialization parameter as Checksum' by calculating the Checksum of the initialization parameter. The display device may determine that the initialization parameter checks pass when Checksum' is the same as Checksum. When Checksum' is different from Checksum, it is determined that the initialization parameter check fails.

It should be understood that the above manner of obtaining the check value of the initialization parameter by calculating the checksum of the initialization parameter is only a possible implementation manner provided by the present application, and the present application is not limited to how the display device obtains the check value of the initialization parameter by a preset check manner. Optionally, the preset standard values corresponding to different preset verification modes may be the same or different.

In some embodiments, the display device may further include a memory storing the initialization parameters of the voltage management component, and the display device may read the initialization parameters of the voltage management component from the memory and then input the initialization parameters of the voltage management component into the initialization program when the display device determines that the initialization parameters are not verified. By the method, when the verification of the initialization parameters stored in the storage component on the TCON board is failed, that is, when the initialization parameters possibly have errors, the initialization parameters stored in the storage component are not used, but the initialization parameters stored in the memory of the display device are used for initializing the voltage management component, so that the accuracy of initializing the voltage management component is improved.

Under the implementation mode, when the verification of the initialization parameters is confirmed to pass, the initialization parameters of the voltage management component are input into the initialization program, and the accuracy of the initialization parameters input into the initialization program is guaranteed through the method, so that the accuracy of initializing the voltage management component is guaranteed, and the accuracy of displaying images of the display equipment is improved.

In some embodiments, the display device may further update the mapping relationship between the model identifier stored in the display device and the initialization program, so as to increase the number of models of the voltage management components that the display device may initialize, so that the display device may be adapted to voltage management components of multiple models, and further improve the development efficiency of the display device.

Optionally, the display device may receive, for example, a mapping relationship between the updated model identifier and the initialization program from the configuration server, and replace the mapping relationship between the original model identifier and the initialization program by using the mapping relationship between the updated model identifier and the initialization program, so as to update the mapping relationship. Alternatively, the display device may periodically receive the updated mapping relationship. Or, the display device may further send an update request to the configuration server in response to an instruction for updating the mapping relationship by the user, so as to receive the mapping relationship between the updated model identifier and the initialization program from the configuration server.

Taking the memory component on the TCON board as an EEPROM, and taking the data shown in table 2 as an example, fig. 5 is a flow chart of another method for initializing the TCON board provided by the present application. As shown in fig. 5, the display device may read data from the EEPROM of the TCON board after the system is powered up and determine whether the data is data of the voltage management component. Taking the data shown in table 2 as an example, the display device can read the 1 st byte of the data and determine whether the byte is a chip identifier. If the data is a chip identifier, the identification of the data represents the data of the voltage management component. The display device may continue to perform subsequent steps.

If not, the identification characterizing data specifying the data is not data of the voltage management component. The display device may continue to read the next data until the display device determines that there is no "data of the voltage management component that has not been read" in the storage component.

After determining the 1 st byte of data as the chip identifier, the display device may read the 2 nd byte of data to determine the model of the chip and the 3 rd byte to obtain I to write initialization data to the registers of the voltage management component, as exemplified in Table 2 ² And a C address.

Exemplary, table 3 shows a byte and voltage management component actual model, and, I ² Examples of mapping relationships between the three addresses:

TABLE 3 Table 3

The mapping relationship as shown in table 3 may be stored in advance in a memory of the display device. The display device can determine the model and I of the voltage management component according to the mapping relation and bytes read from the storage component of the TCON board and used for representing the model ² C address, etc.

The display device may also read a preset standard value Checksum from the 4 th byte of data of the storage component and read the 16 th byte to acquire the data length. According to the length, the display device can acquire the register address representing the voltage management component and the initialization data to be written into the register in the data. The display device may calculate a Checksum over the register address and the initialization data to be written to the register, resulting in Checksum'.

The display device may then determine whether Checksum' is the same as Checksum. If the voltage management components are different, initializing data in a memory of the display device are used for inputting initializing programs corresponding to the types of the voltage management components. If so, the display device may read the existing initialization data from the register of the voltage management component and determine whether the existing initialization data is the same as the initialization data read from the EEPROM.

If the existing initialization data is different from the initialization data read from the EEPROM, the display device inputs the initialization data read from the EEPROM into an initialization program corresponding to the model of the voltage management component, and runs the initialization program, and writes the initialization data read from the EEPROM into a register of the voltage management component to initialize the voltage management component.

If the existing initialization data is the same as the initialization data read from the EEPROM, the display device continues to read the next chip identifier according to the judgment result of whether the length value is a multiple of 16. As shown in table 2, assuming length is equal to 16, the display device can directly read the next chip identifier. If the length is not 16, for example, the last row 08-0F in table 2 has no data, that is, the data length is less than 16, the display device may supplement the data length to 16, and then read the next chip identifier to ensure the accuracy of data reading.

After the display device reads the next chip identifier from the EEPROM, it may continue to determine whether the chip identifier is valid. Whether the chip identifier is valid, i.e. determiningWhether the byte is a chip identifier is broken. If so, the display device may continue to perform I of obtaining the model of the data and writing initialization data to the registers of the voltage management component ² C address, etc., to continue initializing the next voltage management component.

If the next chip identifier is invalid, the optional display device may determine that the initialization of each voltage management component is completed, so that the initialization process may be skipped to perform a screen pointing operation (i.e., the display device may control the at least one voltage management component to provide a voltage to the display screen to enable the display screen to perform image display).
