In this way, the user only has one display output mode in normal use. If the user needs to change the output mode due to changes in the use environment (such as brighter environment during the day and darker at night, or high color temperature is required for viewing, and low color temperature images are required for TV photography). At the same time, it is necessary to readjust the display parameters of each display unit, which not only requires a lot of work, but also requires professional adjustment, which brings great inconvenience to users

Embodiment Construction
[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0013] As shown in the figure, a method for adjusting the balance of the display parameters of the splicing screen includes setting a control computer 1, and connecting the control signal output terminal of the control computer 1 to the control signal input terminal of the first-level display unit 3 through the control line 2, And through the control signal connection line 4, the control signal output end of the upper-level display unit is connected with the control signal input end of the lower-level display unit in turn, and then the control computer 1 is set up with each display unit under different conditions. The display balance database of the R, G, B three primary color parameter values, the establishment of the display balance database includes the following steps: ① When the splicing screen reaches the display balance for the first tim...

The invention discloses a balance conditioning method of the paste-up screen display parameter, it characterized in that a control computer is set, and the control signal output terminal of the control computer is connected with the control signal input terminal of the first display unit via the control line, the control signal output terminal of the higher level display screen unit is connected with the control signal input terminal of the next level display screen unit via the control line, the display balanced data base which possesses parameter values of the three primary colors R, G, B in different conditions of every display screen unit is built in the control computer, the corresponding command is input to choose the relative data group according to demand, the parameter values of the three primary colors R, G, B in the data group are transferred to the corresponding display screen unit to obtain the paste-up screen display output balance in different condition, the advantages are when user utilization environment changes, the corresponding signal is input, the brightness and contrast of the whole paste-up screen can be adjusted as a display screen unit.
Description
technical field [0001] The invention relates to a large-screen splicing display screen, in particular to a method for balancing adjustment of display parameters of the splicing screen. Background technique [0002] The existing combined splicing display screen is composed of multiple independent display screen units, each display unit cannot be completely consistent due to its display characteristics (including signal channels and display components), which leads to the brightness of each display unit , contrast, color temperature, RGB light and dark balance, and RGB three primary colors and other display parameters are inconsistent. In order to obtain a uniformly displayed spliced picture on the combined splicing screen, it is necessary to ensure the consistency of the display output of each display unit by changing the display parameters of each display unit. At present, people's work in this area is mainly to adjust the brightness, contrast, color temperature, RGB brig...
