Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
Referring to fig. 1, fig. 1 is a block diagram of a signal adjusting circuit according to an embodiment.
In this embodiment, the signal adjusting circuit includes: an identification module 100, an analysis module 200, and an adjustment module 300. The identification module 100, the analysis module 200, and the adjustment module 300 are disposed at a data transmission transmitting end. In one embodiment, the recognition module 100, the analysis module 200, and the adjustment module 300 are disposed in a timing controller.
And the identification module 100 is used for acquiring the transmitted line data and identifying the type of each data.
And the analysis module 200, the analysis module 200 is connected to the recognition module 100, and is configured to analyze the line data type according to the type of each data, obtain a standard output amplitude corresponding to the line data type, and generate an adjustment instruction.
And the adjusting module 300, the adjusting module 300 is connected with the analyzing module 200, and is configured to adjust the transmission amplitude of the output data signal according to the adjusting instruction.
In the embodiment of the present invention, the identification module 100 is connected to the analysis module 200, and is configured to acquire and store the line data to be transmitted, identify the type of each data, and output the data and the type of each data to the analysis module 200 when the data needs to be transmitted. In one embodiment, the data type can represent a level state of the pixel data, and the specific data type includes 0 and 1, where 0 represents a negative level and 1 represents a positive level. For example, the data type of the first pixel data is 0, the data type of the second pixel data is 0, and the data type of the third pixel data is 1.
In the embodiment of the present invention, the analysis module 200 is connected to the identification module 100, and is configured to analyze the line data type according to the type of each data, obtain a standard output amplitude corresponding to the line data type, and generate an adjustment instruction to control the adjustment module to adjust the transmission amplitude of the output data signal. Wherein, different data types correspond to different standard output amplitudes, and dynamic matching can be realized.
In one embodiment, the analysis module 200 may obtain the row data types by performing sorting and integration on the types of the data, and analyzing the data type segments with relatively regular rules. For example, after sorting and integrating the types of the data, the row data type is 01010101.
In one embodiment, the analysis module 200 obtains the standard output amplitude corresponding to the line data type, and may obtain the standard output amplitude corresponding to the line data type by building a model of the line data type and the corresponding standard output amplitude in advance, and searching or comparing the line data type in the preset model after obtaining the line data type. The preset model may be an amplitude lookup table, or may be other models capable of representing the corresponding relationship. Taking the amplitude lookup table as an example, the following amplitude lookup table may be set; when the data does not find the related line data type, the line data type can be newly added into the amplitude lookup table, and the corresponding standard amplitude is obtained through operation.

| 01010101 | a |
| 00100100 | b |

| …… | e |
| …… | f |
In the amplitude lookup table in the above example, a plurality of different standards are set for different data types, where the values of a, b, c, and d may be set in combination with the actual data transmission condition. Meanwhile, since the amplitude is low when switching to 1 suddenly after a plurality of consecutive 0's, or when switching to 0 after a plurality of consecutive 1's, a < b < c < d is set according to the frequency of switching between 0 and 1. Such as the usual frequent switching between 0 and 1, the amplitude a may be set lower; the amplitude b is set larger for 2 consecutive switching after 0 or 1.
