[0042] OTP: One Time Program, one-time programmable;

[0043] Gamma: gamma;

[0044] GIR: Global IR Drop, which reduces the difference between small area display and full screen display by adjusting the voltage to change the current value of driving pixels;

[0045] LIR ： Local IR Drop, which improves screen uniformity by adjusting the voltage to change the current value driving the pixel;

[0046] IIC: Inter-Integrated Circuit, integrated circuit bus;

[0047] SPI:Serial Peripheral Interface, serial peripheral interface;

[0048] Flash: non-volatile memory;

[0049] Reg:Register, register;

[0052] DBV: Display brightness Value, display brightness value;

[0053] LUT table: Look-Up-Table, displays the lookup table;

[0054] Bin file: binary file.

[0055] In the production of medium-sized eDP (embedded display panel) modules, all data (such as firmware, gamma, demura, DBI, etc.) are stored in the flash, so the driver chip often reads and writes the flash. Since the driver chip continuously reads and writes the flash, the SPI port level of the flash is continuously occupied by the driver IC, which will cause the flash to be unable to exchange data with external devices through the SPI port, thereby affecting the burning of data.

[0056] In view of the above problems, some solutions have been proposed. For example, the method of burning with SPI alone, that is, after completing the OTP adjustment using IIC, power off, and then power the flash alone, use SPI to write the burning data into the flash at one time, thereby realizing the fast writing of SPI, and then power on the driver chip to perform normal display of the display panel. For another example, the method of burning with IIC alone, that is, first pass the data to the driver chip through IIC, and then control the driver chip to write to the fixed position of the flash, so as to achieve the purpose of storing the data in the flash. However, the above-mentioned method of burning with SPI alone requires all the data to be written, the amount of data is large, the program operation mechanism is more, and it is easy to make mistakes. In the above-mentioned method of burning with IIC alone, the IIC transmission speed is slow, and after writing the data, it is necessary to wait for the driver chip to read and run the data in the flash again before knowing whether the change is effective, which is inefficient.

[0057] To this end, in one embodiment, a data burning method is provided. The data burning method is applied to a display module. The data burning method can quickly complete the burning of optical data without affecting the normal display of the display module.

[0058] Reference Figure 1 The display module 100 includes a display panel 110, a driver chip 120 and a storage chip 130. The driver chip 120 is connected to the display panel 110 and the storage chip 130 respectively. The storage chip 130 stores optical data. The optical data stored in the storage chip 130 may include data such as firmware, gamma, demura, and DBI. During the normal operation of the display module 100, the optical data stored in the storage chip 130 is generally read and loaded by the driver chip 120 to drive the display panel 110 to display output. When the optical data needs to be updated, the optical data to be updated can be written into the storage chip 130, and then read and loaded by the driver chip 120.

[0059] Reference Figure 2 The data burning method provided in this embodiment includes the following steps:

[0060] Step S100 , supplying power to the display module 100 , controlling the driving chip 120 to retrieve the optical data in the storage chip 130 and loading the optical data into the display panel 110 ;

[0061] Step S300, disconnecting the driver chip 120 from the storage chip 130;

[0062] Step S500, determining a display parameter adjustment value and burning the display parameter adjustment value into the storage chip 130;

[0063] Step S700, restoring the connection between the driver chip 120 and the storage chip 130;

[0064] Step S900 , controlling the driving chip 120 to call the display parameter adjustment value in the storage chip 130 and loading it into the display panel 110 .

[0065] The data burning method provided in the embodiment of the present application is that after the driver chip 120 retrieves the optical data in the storage chip 130 and loads it to the display panel 110, the connection between the driver chip 120 and the storage chip 130 is disconnected, and then the display parameter adjustment value is determined and the display parameter adjustment value is burned into the storage chip 130, and then the connection between the driver chip 120 and the storage chip 130 is restored, and then the driver chip 120 is controlled to call the display parameter adjustment value in the storage chip 130 and load it into the display panel 110. In the above-mentioned burning method, when the display parameter adjustment value is burned into the storage chip 130, the storage chip 130 and the driver chip 120 are disconnected. When the burning is completed, the connection between the driver chip 120 and the storage chip 130 is restored, so that the driver chip 120 reads and writes the data in the storage chip 130 to control the display of the display panel 110, that is, the burning process and the display process can be performed independently and do not affect each other, thereby avoiding the problem in the traditional technology that the driver chip 120 continuously occupies the storage chip 130 and the storage chip 130 cannot be burned.

[0066] Reference Figure 4 In step S100 , the display module 100 can be powered normally. After the driver chip 120 is started, the optical data in the storage chip 130 can be retrieved and loaded into the display panel 110 , so that the display panel 110 displays the built-in screen of the output driver chip 120 .

[0067] Reference Figure 5 In step S300, after the display module 100 displays normally, the connection between the driver chip 120 and the storage chip 130 can be disconnected, so that the driver chip 120 enters the all in mode and the saving function is turned off, that is, the operating data of the driver chip 120 all comes from the inside of the driver chip 120, and no data interaction is performed with the storage chip 130.

[0068] Among them, refer to Figure 3-Figure 5 The driver chip 120 and the storage chip 130 may be connected via an SPI interface, and the storage chip 130 may include flash. In step S300, disconnecting the driver chip 120 from the storage chip 130 may refer to releasing the driving of the SPI and the flash.

[0069] In step S500, after the connection between the driver chip 120 and the memory chip 130 is disconnected, the display module 100 can enter a display parameter adjustment mode, which can also be called an OTP adjustment mode, so as to determine a display parameter adjustment value, i.e., an OTP adjustment value, and then burn the display parameter adjustment value into the memory chip 130. Since the driver chip 120 is disconnected from the memory chip 130 during this process, the driver chip 120 will not occupy the interface of the memory chip 130, and the external device can burn the data to be burned into the memory chip 130. Moreover, data burning can be achieved without powering off during this process.

[0070] In one embodiment, referring to Figure 6 The step of determining the display parameter adjustment value in step S500 may further include the following steps:

[0071] Step S510, controlling the display module 100 to enter a display parameter adjustment mode;

[0072] Step S520, adjusting the optical data through the first external interface of the driving chip 120;

[0073] Step S530: determining a display parameter adjustment value according to the display effect when adjusting the optical data.

[0074] First, the display module 100 of normal display can be controlled to enter the display parameter adjustment mode, that is, the OTP adjustment mode. The OTP adjustment mode may include a gamma adjustment mode, a GIR adjustment mode, a LIR adjustment mode, etc. After entering the OTP adjustment mode, the optical data can be adjusted through the external interface of the driver chip 120 (defined as the first external interface in this article), wherein the first external interface may include an IIC interface. Taking the gamma adjustment mode as an example, the internal reg of the driver chip 120 can be adjusted through the IIC interface to seek the optimal gamma setting value so that x, y, and Lv meet the specification value, and then continue to adjust the 32 gamma binding point data, and save the R, G, and B optimal values, and then combine the known gamma binding point data and the interpolation calculation method to calculate the 1024-order gamma value, and save it in a csv table. Finally, based on the 1024-order gamma value, the DBV curve setting LUT table can be calculated by the driver chip 120 algorithm DLL and saved as a bin file, and the bin file can be stored according to 4K integer multiples of data.

[0075] Corresponding to various OTP adjustment modes, the finally determined OTP adjustment value may include at least one of a gamma adjustment value, a GIR adjustment value, and a LIR adjustment value.

[0076] In one embodiment, in step S500, in the step of burning the OTP adjustment value into the memory chip 130, the OTP adjustment value can be burned into the memory chip 130 through the second external interface of the memory chip 130. That is, after the OTP adjustment value is determined, the OTP adjustment value can be burned into the memory chip 130 through the external interface of the memory chip 130 (defined as the second external interface in this embodiment).

[0077] Among them, refer to Figure 3-Figure 5 The second external interface may include an SPI interface. Specifically, the bin file may be burned into the flash through the 4wire SPI interface.

[0078] In step S700, after the programming is completed, the connection between the driver chip 120 and the storage chip 130 can be restored. Specifically, after the programming is completed, an instruction can be sent to the driver chip 120 through the IIC interface to connect the driver chip 120 to the SPI and flash driver, thereby realizing the connection between the driver chip 120 and the flash.

[0079] In step S900 , when the driver chip 120 and the memory chip 130 are restored to be connected, the driver chip 120 can call the OTP adjustment value burned into the memory chip 130 and load it to the display panel 110 so as to adjust the optical display effect according to the OTP adjustment value.

[0080] In one of the embodiments, after step S900, i.e., the step of controlling the driver chip 120 to call the OTP adjustment value in the storage chip 130 and load it to the display panel 110, the data burning method provided in this embodiment also includes: confirming the optical display effect of the display panel 110, and if the optical display effect does not meet the preset requirements, returning to execute the step of disconnecting the driver chip 120 from the storage chip 130.

[0081] In practical applications, the optical display effect of the display panel 110 can be confirmed by an optical probe. If the optical display effect does not meet the preset requirements, it is necessary to re-debug and burn, that is, return to step S300 to step S900. If the optical display effect meets the preset requirements, the subsequent screen detection process can be carried out and the OTP station operation is completed.
