1. A matching method for manufacturing a liquid crystal display (LCD) device, comprising:
acquiring luminance data of a plurality of backlight modules and transmittance data of a plurality of LCD panels under a same driving condition;
acquiring N backlight groups by grouping the plurality of backlight modules based on the luminance data, the luminance data of the backlight modules in different backlight groups being within different luminance ranges;
acquiring N panel groups by grouping the plurality of LCD panels based on the transmittance data, the transmittance data of the LCD panels in different panel groups being within different transmittance ranges; and
determining a corresponding relationship between the backlight groups and the panel groups, wherein the corresponding relationship indicates matching between a target backlight module and a target LCD panel in pairs, and indicates one-to-one correspondence between the N backlight groups in a descending order of representative values of the luminance range and the N panel groups in an ascending order of representative values of the transmittance range, the target backlight module being any one of the plurality of backlight modules, the target LCD panel being an LCD panel in the panel group corresponding to the backlight group to which the target backlight module belongs, and the target backlight module and the target LCD panel matched in pairs being configured to be assembled to form the LCD device;
wherein N is an integer greater than 1;
a distribution of the luminance data of the plurality of backlight modules satisfies a normal distribution, and grouping the plurality of backlight modules based on the luminance data comprises: grouping the plurality of backlight modules based on a standard normal distribution function; and
a distribution of the transmittance data of the plurality of LCD panels satisfies the normal distribution, and grouping the plurality of LCD panels based on the transmittance data comprises: grouping the plurality of LCD panels based on the standard normal distribution function.
