Description

Technical Field

[0001] This application relates to the field of display technology, specifically to a controller driving method, apparatus, device, and storage medium for a display panel. Background Technology

[0002] During the production of liquid crystal displays (LCDs), differences in processes and materials can cause deviations in the gamma curve of each TFT LCD panel (inter-panel difference). This requires adjusting the grayscale mapping relationship and the gamma reference voltage to regulate the panel's gamma. Factories correct gamma by adjusting the grayscale mapping relationship of each panel (digital gamma binding), a process known as digital gamma compensation (DGC).

[0003] When the Tcon (timing controller) powers on / reboots, it first downloads the FW code (Firmware, software embedded in memory that provides functionality for the Tcon's underlying operating system) from the C-Board flash (the control board's first memory). Then, it loads the data from the DGC storage location in the X-Board flash (the X board's second memory) and checks if the location contains data. If so, the DGC LUT is loaded into the DGC IP within the Tcon; otherwise, the default LUT in the C-Board flash is loaded. This process of checking the X-Board flash for DGC data increases the Tcon's boot time. The default LUT is a set of default LUTs (Gamma compensation tables, i.e., initial gamma compensation data) stored in the C-Board flash, while the DGC LUT is the compensation data in the X-Board flash after factory gamma adjustment. Summary of the Invention

[0043] Please see Figure 1 This application provides a timing controller driving method, which includes steps S101 to S103, as follows:

[0044] S101, download firmware from the first memory of the control board.

[0045] Specifically, when the control board (C-Board) is powered on, the timing controller (Tcon) downloads firmware (FW code) from the control board's first memory (C-Board flash). FW code is the software embedded in the memory, providing the functionality of the Tcon's underlying operating system. The timing controller downloads the firmware based on a pre-configured strategy, which is equivalent to activating the timing controller, allowing it to continue executing subsequent operations.

[0046] S102, After the firmware is downloaded, the drive data in the second memory of the X board is read.

[0047] Specifically, after the firmware download is complete, the timing controller reads the driving data stored in the second memory of the X board. The driving data is used by the timing controller to drive compensation to achieve better display effects, including but not limited to optical compensation data (Demura), calibration grayscale value WT (white tracking), and viewing angle VAC (View Angle Compensation) data.

[0048] In one embodiment, before downloading the firmware from the first memory in step S101, the method further includes: S201, writing the gamma compensation data into the second memory, and writing the driver data with the newly added identification information into the second memory.

[0049] Specifically, during the manufacturing process of the display panel, initial gamma compensation data (default LUT) is written into the first memory of the control board. This default LUT is a set of default gamma compensation data stored in the first memory of the control board, and all display panels use the same default LUT. However, different display panels may have some differences, so directly using the initial gamma compensation data may not provide adequate compensation, resulting in poor display quality.

[0050] Therefore, individual experimental analysis can be conducted for each display panel to determine the applicable gamma compensation data DGC LUT for that display panel. The gamma compensation data DGC LUT is then written into the second memory of the X board. In other words, the gamma compensation data DGC LUT is the compensation data for each display panel after factory adjustment of gamma in the second memory of the X board. On one hand, based on the fabrication and programming process, the initial gamma compensation data default LUT and the gamma compensation data DGC LUT are written into the first memory of the control board and the second memory of the X board, respectively. On the other hand, only one needs to be selected during compensation, so storing them separately avoids confusion.

[0051] Furthermore, since the display panel has two scenarios: the second memory of the X board stores gamma compensation data DGC LUT and the second memory of the X board does not store gamma compensation data DGC LUT, even if the second memory of the X board does not store gamma compensation data DGCLUT, the timing controller still needs to load the storage space of the gamma compensation data DGC LUT when reading the drive data in the second memory of the X board. Taking a 10-bit LUT as an example, the storage space for storing gamma compensation data DGC LUT is about 6KBytes, which obviously takes a long time.

[0052] Therefore, in order to facilitate quick identification, new identification information is added to characterize whether the second memory of the X board stores gamma compensation data DGC LUT. Since the timing controller itself needs to read the drive data in the second memory of the X board during the power-on process, adding identification information to the drive data can avoid the need for the second memory of the X board to set up a separate storage space to store the identification information, and can also avoid the need for the timing controller to read and load new data.

[0053] In one embodiment, the timing controller performs multiple compensation adjustments based on the driving data, including but not limited to optical compensation data (Demura), calibration grayscale value WT (white tracking), and view angle compensation VAC. These compensations are performed in a specific order within the timing controller; for example, the timing controller typically performs optical compensation first, followed by gamma compensation. Before performing gamma compensation, the identification information in the driving data needs to be identified. Therefore, the driving data can be set as optical compensation data. To avoid affecting the parameter data used for compensation in the optical compensation data, identification information is added to the header file of the optical compensation data (XB flash Demura file header) to indicate whether gamma compensation data DGC LUT is stored in the second memory of the X-board.

[0054] In one embodiment, a bit is added to the header file of the optical compensation data to indicate whether gamma compensation data is stored in the second memory of the X board. The identification information includes the data name, the corresponding identification information, and the identification description information. The identification information corresponding to the data name includes preset first identification information and preset second identification information. The identification description information includes whether gamma compensation data is stored in the second memory corresponding to the preset first identification information and whether gamma compensation data is stored in the second memory corresponding to the preset second identification information. As shown in Table 1, the data name is dgc_lut_empty, and the identification information corresponding to the data name is 0 or 1. The first identification information is 1, and the second identification information is 0. The identification description information of the first identification information 1 indicates that DGC data is present in the second memory of the X board, and the identification description information of the second identification information 0 indicates that DGC data is not present in the second memory of the X board. Generally, the header file of the optical compensation data reserves a certain number of bits to facilitate the addition of new parameters. Therefore, adding identification information to the header file of the optical compensation data does not require deletion and will replace the original data. Furthermore, the header file of the optical compensation data needs to be read before the timing controller loads the gamma compensation data, thus further saving the power-on time of the timing controller. Compared to the timing controller reading the storage space of the second memory of the X board to load the gamma compensation data DGC LUT, the amount of data with added bit identification information in the header file of the optical compensation data is smaller, and the reading speed is faster.

[0055] Table 1

[0056]

[0057]

[0058] S103, if the identification information in the driving data is a preset first identification information, then the initial gamma compensation data in the first memory is loaded, and the preset first identification information indicates that gamma compensation data is not stored in the second memory.

[0059] Specifically, if the identification information in the driving data is the preset first identification information, the preset first identification information indicates that the second memory of the X board does not store gamma compensation data. It is possible that due to cost or other factors, no separate gamma adjustment analysis was performed for the display panel. As shown in Table 1, if the identification information is added to the header file of the learning compensation data, when the value of dgc_lut_empty is 1, it means that the second memory of the X board does not store gamma compensation data. In this case, only the initial gamma compensation data stored in the first memory of the control board can be loaded.

[0060] In one embodiment, after reading the driving data in the second memory in step S102, the method further includes: S301, if the identification information in the optical compensation data is a preset second identification information, then the gamma compensation data in the second memory is loaded, wherein the preset second identification information indicates that gamma compensation data is stored in the second memory.

[0061] Specifically, if the identification information in the driver data is the preset second identification information, the preset second identification information indicates that the second memory of the X board stores gamma compensation data, as shown in Table 1. If the identification information is added to the header file of the learning compensation data, when the value of dgc_lut_empty is 0, it means that the second memory of the X board stores gamma compensation data, then the gamma compensation data stored in the second memory of the X board is loaded.

[0062] In summary, based on Table 1, as follows: Figure 2 As shown, a timing controller driving method includes the following steps:

[0063] 1) Power on the control board (C-Board);

[0064] 2) The timing controller (Tcon) downloads firmware (FW code) from the first memory (C-Board flash);

[0065] 3) The timing controller reads the identification information (e.g., the value of dgc_lut_empty) from the drive data in the second memory (X-Board flash) to make a judgment;

[0066] 4) If the identification information in the driver data is the preset second identification information 0, proceed to step 5); if the identification information in the driver data is the preset first identification information 1, proceed to step 6.

[0067] 5) The timing controller loads the gamma compensation data (DGC LUT) from the second memory into the gamma compensation module (DGCIP);

[0068] 6) The timing controller loads the initial gamma compensation data (default DGC LUT) from the first memory into the gamma compensation module.

[0069] In one embodiment, step S103, if the identification information in the driving data is a preset first identification information, then loading the initial gamma compensation data in the first memory includes: determining the identification description information corresponding to the identification information based on a preset identification information mapping relationship; S402, if the identification description information is gamma compensation data not stored in the second memory, then loading the initial gamma compensation data in the first memory.

[0070] Specifically, in the above embodiments, the premise for adding identification information to the header file of optical compensation data is that the header file of optical compensation data has reserved free bits, or although the header file of optical compensation data does not have reserved free bits, replacing the identification information with data in some bits of the header file of optical compensation data will not cause other effects.

[0071] When it's impossible to add identification information to the header file of the optical compensation data, a separate storage space can be allocated in the second memory to store the identification information and a preset identification information mapping relationship. In the preset identification information mapping relationship, the identification information and the identification description information correspond one-to-one, and the identification description information explains whether gamma compensation data is stored in the second memory. As long as the amount of data in the identification information and the preset identification information mapping relationship is less than the amount of gamma compensation data stored in the second memory, the power-on time of the timing controller can also be saved.

[0072] If the identifier description indicates that gamma compensation data is stored in the second memory, then the gamma compensation data stored in the second memory is loaded into the DGC IP. If the identifier description indicates that gamma compensation data is not stored in the second memory, then the initial gamma compensation data stored in the first memory is loaded into the DGC IP.

[0073] In one embodiment, step S103, if the identification information in the driving data is a preset first identification information, then after loading the initial gamma compensation data in the first memory, further includes: S501, obtaining initial pixel driving parameters; S502, compensating the initial pixel driving parameters according to the initial gamma compensation data and the optical compensation data to obtain target pixel driving parameters.

[0074] Specifically, gamma compensation data or initial gamma compensation data is used for gamma compensation to calibrate grayscale values. Optical compensation data is used for optical compensation to improve uneven display. Both involve compensating and adjusting the data driver, thus obtaining initial pixel driving parameters. These initial pixel driving parameters include, but are not limited to, the data of each pixel. If initial gamma compensation data is obtained, the initial pixel driving parameters are compensated based on the initial gamma compensation data and optical compensation data. If gamma compensation data is obtained, the initial pixel driving parameters are compensated based on the gamma compensation data and optical compensation data. Finally, the target pixel driving parameters are obtained and output to the X-plate. Other compensation steps, such as increasing the viewing angle (VAC), will not be described in detail in this embodiment.

[0075] This embodiment sets an identification information in the driving data in the second memory to indicate whether gamma compensation data is stored in the second memory. This eliminates the need for the timing controller to load the storage space in the second memory where gamma compensation data is stored to determine whether gamma compensation data is stored. The time required for the timing controller to read the identification information is much less than the time required to load the storage space in the second memory where gamma compensation data is stored, thereby saving the power-on time of the timing controller.
