The LED display will inevitably produce tail goods when selling. Tail goods are different batches of products. It is inevitable that the brightness will be different, and the display effect is not good after assembly. This situation needs to be corrected one by one.

Eliminate differences by pointing by point is the technology that improves the uniformity and color preservation of the LED electronic screen. By collecting the pixels of the LED display screen, the matrix of the corrected coefficient is given to the control system to achieve the difference in pixels to achieve the difference in pixels Finally, weakening the brightness and color differences can be connected to different batches of tails. The screen shows pure and delicate, color and real nature.

LED display

According to application occasions, the correction system is divided into two types.

1. A single LED box is corrected one by one, and the box is corrected during production to ensure that each box is uniform after the production of each box.

2. On -site large -screen correction one by one, the full color LED screen display the appropriate observation location on the spot for on -site correction to ensure that the height of the observation location is uniform.

Correct the color and brightness little by little.

1. Poly -color correction refers to a light detector correction with strong color recognition capabilities, which can accurately measure the brightness and color value of the LED display.

2. Brightness correction is the correction of LED light emitting intensity. Some correction equipment lacks good color recognition capabilities, cannot correctly measure the difference in spectrals, can only measure the light emitting intensity, and cannot correctly measure the color deviation of its color.
