[0031] Such as figure 1 as shown, figure 1 It is a flow chart of a method for checking the effect of cabinet correction provided by the first embodiment of the present invention. The method includes the following steps:

[0032]Step 1. Obtain N simulated cabinets from M cabinets, where M is greater than or equal to N, and M and N are natural numbers;

[0033] Step 2, obtaining the correction coefficients of the N simulated cabinets;

[0034] Step 3. Draw a simulation diagram according to the correction coefficient and preset simulation parameters, so as to find out whether there is a problematic cabinet among the N simulated cabinets based on human visual observation.

[0035] Wherein, for step 1, it may be to select all, random multiple, front multiple, rear multiple or intermediate multiple cabinets as the N simulated cabinets from the M corrected cabinets.

[0036] Among them, for step 2, for the RGB full-color LED cabinet, each pixel includes red (R), green (G) and blue...

Abstract

The embodiment of the invention discloses a method and a device for checking correction effects of a box body. The method comprises steps of acquiring N simulation box bodies from M box bodies; acquiring correction coefficients of the N simulation box bodies; and according to the correction coefficients and a preset simulation parameter, drawing a simulation graph so that whether a defective box body exists in the N simulation box bodies can be found through visual observation of human eyes. According to the embodiment of the invention, simulation processing is performed on the correction coefficients of the corrected box bodies; brightness distribution of the box bodies before correction is simulated; correction effects of the box bodies are checked in an auxiliary manner; and splicing effects of corrected box bodies can be checked with no need to put up the boxes into the whole screen.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a method for viewing the correction effect of a cabinet and a device for viewing the correction effect of a cabinet. Background technique [0002] Today's LED display has become a mainstream information medium. In order to meet the different needs of customers, product diversification and technology are constantly being upgraded. LED display point-by-point calibration technology mainly solves the problem of poor brightness and chromaticity consistency of LED displays. With the improvement of people's display quality requirements, more and more manufacturers will perform point-by-point calibration before shipment. According to different application occasions, the point-by-point calibration technology can be divided into two types: one is box-by-box calibration on the production line (cabinet calibration); the other is on-site large-screen calibration (on-site calibration)...
