Embodiment 1

[0028] According to an embodiment of the present invention, an embodiment of a method for sending a correction coefficient is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and , although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0029] figure 1 is a flow chart of a method for sending correction coefficients according to an embodiment of the present invention. Such as figure 1 As shown, the sending method of the correction coefficient may include the following steps:

[0030] Step S102, the first sending step, the sending card sequentially sends the corresponding data packets to the target cabinets under the multiple network ports of the display screen.

[0031] In the technical solution provided by the above-mentione...

Embodiment 2

[0060] The technical solutions of the embodiments of the present invention will be further introduced below in combination with preferred implementation modes, specifically, the display screen is an LED display screen.

[0061] When performing point-by-point calibration on the LED display, it is necessary to cooperate with the LED display point-by-point calibration system and the LED display control system, such as figure 2 As shown, among them, figure 2 It is a schematic diagram of a point-by-point correction system for an LED display screen according to an embodiment of the present invention. The point-by-point correction system 20 includes: a point-by-point correction system 21 for an LED display screen and a control system 22 for an LED display screen. Wherein, the LED display screen point-by-point correction system 21 includes: a correction computer 211, a correction software 212 and a camera 213 for generating correction coefficients, and the LED display screen control...

Embodiment 3

[0107] The embodiment of the present invention also provides a correction coefficient sending device. It should be noted that the apparatus for sending the correction coefficient in this embodiment can be used to implement the method for sending the correction coefficient in the embodiment of the present invention.

Abstract

The invention discloses a correction coefficient sending method and device, a storage medium and a processor. The method comprises the following steps: a first sending step: enabling a sending card to send corresponding data packets to a target box body of a display screen under a plurality of network ports in sequence, wherein the data packets comprise correction coefficients for correcting target pixels, and the target pixels are pixels of the target box body; and a first judgment step: judging whether the target box body is the last box body of the plurality of box bodies under each network port or not by the sending card, if not, determining the next adjacent box body of the target box body in the plurality of box bodies as the target box body, and returning to the first sending step until the target box body is the last box body. According to the invention, the technical problem of long time consumption for sending the correction coefficient to the box body of the display screen is solved.

Description

technical field [0001] The present invention relates to the field of display screens, in particular to a method, device, storage medium and processor for sending correction coefficients. Background technique [0002] At present, the sending card analyzes the correction coefficients of the pixels of the display screen according to the protocol in the first data packet, and sends them to the cabinet of the display screen according to the network port to which the first data packet belongs. After the cabinet receives its own correction coefficient, the cabinet starts to save the correction coefficient into the memory. The time length of this process is also different under the condition of different cabinets. The host machine waits for a period of time, and then sends the second data packet. Repeat the above steps to send the calibration coefficient of the cabinet under one network port, and then follow the above steps to send the calibration coefficients of the other cabinet...
