Embodiment Construction

[0018] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] The splicing bright and dark line adjustment method in the technical solution proposed by the following embodiments of the present invention saves the adjustment position and adjustment amount as a file in real time during the adjustment process, and sends the saved file to the LED display control at one time after all adjustments are completed. System hardware, at the same time, when sending the saved files to the LED display control system hardware, you can choose to send them to volatile memory (RAM) or non-volatile memory such as Flash (flash memory). If it is sent to RAM, the adjustment coefficient will be lost after the LED display control system hardware is powered off, which is suitable for LED screen rental occasions; if...

Abstract

The invention puts forward a splicing bright / dark line adjustment method comprising the following steps: (i) getting the position information and resolution information of multiple splicing units, drawing a distribution diagram of the multiple splicing units, and marking out the boundaries of the multiple splicing units in the distribution diagram; (ii) selecting a first boundary needing adjustment and adjusting the first boundary so as to check the adjustment effect based on human vision until the splicing bright / dark lines at the first boundary are adjusted to a target state, for example, the splicing bright / dark lines are eliminated completely or basically; (iii) saving the adjustment position and adjustment value (such as brightness adjustment coefficient) corresponding to the first boundary to a file; and (iv) selectively sending the saved file to either a volatile memory or a nonvolatile memory of LED display control system hardware. Therefore, the problems in the prior art, such as high sending frequency, complicated operation and difficult revocation, are solved.

Description

technical field [0001] The invention relates to the technical field of display correction, in particular to a splicing bright and dark line adjustment method. Background technique [0002] LED display screen is a flat panel display device composed of LED dot matrix. Generally, a LED display screen is spliced ​​by several LED cabinets or LED display modules (here collectively referred to as splicing units). Each splicing unit has It can be calibrated in the factory to ensure that the uniformity of the LED display screen is good when it leaves the factory. However, due to the limitations of machining accuracy, assembly accuracy and other technological reasons during the splicing process, the edge of the adjacent splicing unit at the splicing unit and the splicing unit The distance between the LED light spots may be greater or smaller than the pixel center distance of the LED light spots in other places, which is called the splicing gap; at this time, the luminous density of th...
