[ first embodiment ] A method for manufacturing a semiconductor device

Referring to fig. 1, a display device 10 according to a first embodiment of the present invention, as shown in fig. 1, includes: the liquid crystal display device comprises a liquid crystal display panel 11, a horizontal driving circuit board (XB) 12 connected with the liquid crystal display panel 11, a time sequence control Circuit Board (CB) 13 connected with the horizontal driving circuit board 12 and a time sequence control module 14.

The horizontal driving circuit board 12 includes, for example, a memory 121, the timing control circuit board 13 includes, for example, a memory 131, and the timing control module 14 is electrically connected to the memory 121, the memory 131, and the liquid crystal display panel 11.

Among them, the memory 121 stores a target panel information table including: target timing control information and target image processing parameters associated with the target timing control information. The timing control module 14 is configured to: the target panel information table stored in the read memory 121 is stored in the memory 131, the target timing control information is read from the memory 131 to determine a target timing control program, and the target timing control program is executed to read the target image processing parameters from the target display information table, perform image processing on input image data based on the target image processing parameters, and output the input image data to the liquid crystal display panel 11 for display.

The memory 121 and the memory 131 are referred to as nonvolatile memories such as Flash. The target timing control program referred to is the target TCON code. The target image processing parameters mentioned include, for example: ACC table, i.e. white balance compensation table, OD table, i.e. overdrive compensation table, dual gamma table, i.e. gamma adjustment table, and the like, and further, may further include the original DeMura table.

Further, as shown in fig. 2, the liquid crystal display panel 11 includes, for example: a display cell array 111, a source driving circuit 112, and a gate driving circuit 113. The source driving circuit 112 and the gate driving circuit 113 are electrically connected to the display cell array 111. The source driving circuit 112 includes a plurality of source drivers, for example, the source drivers are Chip On Film (COF) chips including source driving chips. The gate drive circuit 113 includes, for example, a plurality of gate drivers. The horizontal driving circuit board 12 connects the source driving circuit 112 and the gate driving circuit 113.

The display device 10 further includes, for example: a multimedia system motherboard 15 connected to the timing control circuit board 13,. The timing control module 14 is disposed on the timing control circuit board 13, for example, although the invention is not limited thereto, the timing control module 14 may also be disposed on the multimedia system motherboard 15. The timing control module 14 is disposed on the timing control circuit board 13 and is a timing control chip (TCON IC), and the multimedia system main board 15 is disposed with a System On Chip (SOC) 151, for example. When the timing control module 14 is disposed on the multimedia system main board 15, the timing control module 14 is, for example, a system-on-chip.

The memory 131 stores, for example, an initial timing control program, i.e., an initial program of the TCON IC. As shown in table 1, the aforementioned target timing control parameters include, for example, target panel architecture information, and the mentioned target panel architecture information represents the architecture of the current panel, which is, for example, a conventional architecture (stripe), a one-line flip architecture (1 line flip), or a two-line flip architecture (2 line flip).

TABLE 1 target Panel information Table

The aforementioned timing control module 14 is configured to read the target timing control information from the memory 131 to determine a target timing control program, which specifically includes: determining a corresponding data mapping relation based on the target panel architecture information; and reading the initial timing control program from the memory 131, and modifying the initial timing control program based on the data mapping relationship to obtain the target timing control program.

It can be understood that the data mapping relationships (data mapping) corresponding to different target panel architecture information are different. For example, strip does not need to insert dummy into the mini-LVDS image data, 1line flip needs to insert dummy into the mini-LVDS image data in an interlaced mode, and 2line flip needs to insert dummy into each 2 lines of the mini-LVDS image data. The TOCN code (time sequence control program) corresponding to different data mapping relations is different. Therefore, the timing control module 14 reads the target panel architecture information from the memory 131 so as to determine the corresponding data mapping relationship, and then modifies the initial timing control program to obtain the target timing control program.

In other embodiments of the present invention, the target timing control information includes, for example: the system comprises an initial time sequence control program, a target chip identification and a target chip initial program corresponding to the target chip identification. The timing control module 14 is specifically configured to: reading the target chip identification from the memory 131 to determine a corresponding program data conversion format based on the target chip identification; reading the initial timing control program from the target panel information table saved in the memory 131, and modifying the initial timing control program based on the program data conversion format to obtain the target timing control program; executing the target time sequence control program to read the target chip initial program from the target panel information table saved in the memory 131, perform format conversion on the target chip initial program based on the program data conversion format, and send the converted program to the target chip corresponding to the target chip identifier, and read the target image processing parameter from the target panel information table saved in the memory 131, perform image processing on the input image data based on the target image processing parameter, and output the processed image data to the liquid crystal display panel 11 for display.

The target chip identifier is, for example, an identifier of a Gamma chip (Gamma IC) and/or an identifier of a power chip (PM IC). Different chip types correspond to different chip programs and thus to different TCON codes. Specifically, as shown in table 2, the target chip identifier is exemplified by a Gamma IC identifier and a PM IC identifier.

TABLE 2 target Panel information Table

The timing control module 14 is specifically configured to: reading a Gamma IC identifier and a PM IC identifier from a memory 131 to determine a program data conversion format corresponding to the Gamma IC and a program data conversion format corresponding to the PM IC, reading an initial time sequence control program (TCON code) from a target panel information table stored in the memory 131, modifying the initial time sequence control program based on the program data conversion format corresponding to the Gamma IC and the program data conversion format corresponding to the PM IC to obtain the target time sequence control program, executing the target time sequence control program to read the Gamma IC code from the target panel information table stored in the memory 131, format-convert the Gamma IC code based on the program data conversion format corresponding to the Gamma IC and send the Gamma IC code to the Gamma IC, read the PM IC code from the target panel information table stored in the memory 131, format-convert the PM IC code based on the program data conversion format corresponding to the PM IC and send the PM IC code to the PM IC, and read AC table, PM IC code and the target panel information table stored in the memory 131 to output and display image data 11. The target chips of different models can be matched through the design, the condition that a plurality of versions of TCON codes occur is avoided, and users do not need to worry about burning errors of the TCON codes.

In other embodiments of the present invention, the aforementioned target panel information table, i.e., table 2, may also not contain the initial timing control program, i.e., the aforementioned initial timing control program is stored in the memory 131.

In other embodiments of the present invention, the aforementioned target panel information table may further include other information, for example, TCON IP ON/OFF information, and the timing control module 14 is further provided with some specific functions, and the corresponding target panel information table may include information about whether the specific function is in an open state or in a closed state.

It should be noted that the specific content of the target timing control information included in the target panel information table is not limited in the present invention, and in principle, the information that can affect the setting of the TCON code may be set in the target panel information table.

Further, the target panel information table in the aforementioned embodiment further includes, for example: and (4) representing a target information table identification (checksum) of the target panel information table. The timing control module 14 is further configured to: reading the target information table identification stored by memory 131 in response to a power-up being resumed; judging whether the target information table identifier stored in the memory 131 is the same as the information table identifier currently stored in the memory 121; in response to the target information table id stored in memory 131 being different from the information table id currently stored in memory 121, the panel information table stored in memory 121 in association with the information table id is read and stored in memory 131 to replace the target panel information table stored in memory 131.

Further, the timing control module 14 is further configured to: in response to the target information table id stored in the memory 131 being identical to the information table id currently stored in the memory 121, the panel information table stored in the memory 121 need not be read and stored in the memory 131.

In short, after subsequent boot, i.e. powering on again, the timing control module 14 will first determine whether the identifiers of the information tables stored in the memory 131 and the memory 121 are the same, if the identifiers are the same, it indicates that the panel information table stored in the memory 121 is not changed, and if the target panel information table stored in the memory 131 is the same as the panel information table stored in the memory 121, it is not necessary to download the panel information table again; if the two tables are different, the panel information table stored in the characterization memory 121 is changed, and the panel information table stored in the characterization memory 121 needs to be downloaded to the memory 131 again.

In summary, in the display device 10 disclosed in this embodiment, the target panel information table is stored in the memory 121, and the target panel information table includes target panel architecture information, gamma chip information, power chip information, image processing parameters, and the like, and the target panel information table stored in the memory 121 is electrically read by the timing control module 14 and stored in the memory 131 to execute the target TCON code, so that a situation that the display device is abnormal due to mixed use of a plurality of versions of timing control programs in the related art can be avoided, complete universality of the full-size timing control circuit board can be realized, a situation that the mixed material or the TCON code is burnt erroneously is not needed, development and design time is shortened, labor cost for product development and design is reduced, and a debugging process is simplified.
