Problems solved by technology

However, since the fixed-frequency video refresh period is fixed, but in fact the transmission time of each field of image data is not the same, so a frame of picture may not be completely transmitted within the fixed refresh period, or the transmission is completed but there is free time, etc. resulting in flickering
[0003] In the prior art, the user needs to set the field frequency at the sending card, and then issue the configuration parameters of the receiving card including field frequency related parameters through the upper computer LCT software to set the field frequency related parameters of the receiving card. This kind of application operation is complicated. Bad user experience

Abstract

An embodiment of the invention discloses a parameter adjustment method and device and a display system. The method is characterized by receiving input field frequency information; searching an internal traversal list according to the field frequency information to obtain target group image output control parameters corresponding to the field frequency information; and carrying out configuration parameter update according to the target group image output control parameters. The matched image output control parameters related to field frequency can be searched adaptively for configuration parameter update, so that image display effect is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a parameter adjustment method, a parameter adjustment device and a display system. Background technique [0002] In the LED display control system, the screen displayed on the receiving card is actually displayed sequentially by stacking data one by one. Since the refresh frequency of the LED display screen is much higher than the visual refresh frequency of the human eye, Therefore, the picture seen by human eyes will be a continuous picture display. However, since the fixed-frequency video refresh period is fixed, but in fact the transmission time of each field of image data is not the same, so a frame of picture may not be completely transmitted within the fixed refresh period, or the transmission is completed but there is free time, etc. resulting in flickering. [0003] In the prior art, the user needs to set the field frequency at the sending card, and then issue...
