1. A display device, comprising:
a display panel comprising a plurality of gate lines and a plurality of data lines, wherein the plurality of gate lines intersect and are insulated with the plurality of data lines, the display panel further comprises a plurality of sub-pixels arranged in an array, and the plurality of gate lines and the plurality of data lines define areas where the sub-pixels are located;
a gate driver electrically connected to the plurality of gate lines in the display panel; and
a source driver bound to the display panel and electrically connected to the plurality of data lines in the display panel, wherein the source driver is configured to set data transmission start time for respective data lines, so that effective charging time of respective sub-pixels formed by the plurality of data lines and a same gate line is same, wherein:
the source driver comprises a source driving unit;
the gate driver is configured to transmit a gate signal in a first preset time range to the gate line;
the source driving unit is configured to transmit data signals to the plurality of data lines, any of a plurality of data lines intersecting a same gate line is taken as a first reference data line, and data transmission start time of the first reference data line is taken as reference time;
in a case that among the plurality of data lines intersecting the same gate line, a gate signal on the gate line at an intersection with the first reference data line is transmitted earliest, data transmission start time of data lines except the first reference data line among the plurality of data lines is later than the reference time, so that effective charging time of respective sub-pixels formed by the plurality of data lines electrically connected to the source driving unit and the same gate line is the same;
in a case that among the plurality of data lines intersecting the same gate line, the gate signal on the gate line at the intersection with the first reference data line is transmitted latest, data transmission start time of the data lines except the first reference data line among the plurality of data lines is earlier than the reference time, so that effective charging time of respective sub-pixels formed by the plurality of data lines electrically connected to the source driving unit and the same gate line is the same;
in a case that among the plurality of data lines intersecting the same gate line, the gate signal on the gate line at the intersection with the first reference data line is transmitted midway, among the plurality of data lines, data transmission start time of a data line of which a data signal is transmitted earlier than the gate signal on the gate line at the intersection with the first reference data line is earlier than the reference time; and among the plurality of data lines, data transmission start time of a data line of which a data signal is transmitted later than the gate signal on the gate line at the intersection with the first reference data line is later than the reference time, so that the effective charging time of the respective sub-pixels formed by the plurality of data lines electrically connected to the source driving unit and the same gate line is the same;
the source driving unit comprises a data input module, a multi-channel delay control module, a digital-to-analog conversion module, an output module and a logic control module;
the data input module is electrically connected to both the logic control module and the multi-channel delay control module, and is configured to: receive and analyze a video signal under control of a first control signal of the logic control module, to obtain first data of the video signal; and transmit the first data to the multi-channel delay control module;
the multi-channel delay control module is electrically connected to both the logic control module and the digital-to-analog conversion module, and is configured to: receive and analyze the first data under control of a second control signal of the logic control module, to obtain second data of respective data lines with different start time; and transmit the second data to the digital-to-analog conversion module;
the digital-to-analog conversion module is further electrically connected to the output module and is configured to: receive and convert the second data, to obtain third data; and transmit the third data to the output module; and
the output module is configured to receive and output the third data.
