Abstract: This application discloses a configuration update method for an LED display screen, a receiver card, an LED display module, and an LED display screen. The method includes: (S201) when it is detected that a receiver card is powered on, reading storage identity authentication data of the receiver card, and verifying whether the receiver card has been replaced; (S202) when it is determined that the receiver card has been replaced, outputting a configuration parameter stored in a memory to the receiver card, to update a configuration parameter of the receiver card; (S203) when it is detected that an LED display module is powered on, reading display identity authentication data of the LED display module, and verifying whether the LED display module has been replaced; and (S204) when it is determined that the LED display module has been replaced, outputting correction data of the LED display module to the receiver card.

Abstract: This application discloses a support frame and an LED display screen system including the support frame. An LED display screen includes a plurality of splicing units that are spliced to each other. The support frame includes a bracket and a first rod extending in a first direction. The bracket includes a second rod and a first connection assembly, and one end of the second rod is connected to the first rod and extends in a second direction.

Abstract: A color display panel and a control method thereof are provided. The color display panel includes pixel units arranged in an array, and each pixel unit at least includes a red sub-pixel unit, a green sub-pixel unit, a blue sub-pixel unit, and a white sub-pixel unit, where white light of the color display panel is achieved through the white sub-pixel unit. With aid of the above, the white light of the color display panel of the disclosure is realized by a single white sub-pixel unit, which can effectively alleviate color separation during mixing of red, green, and blue light of traditional display panels, and greatly improve the display effect of the display panel.
