There are inevitably some LED displays left during selling. As these products come from different batches, the luminance of these is different. Therefore, the point-by-point calibration technology has to be applied to improve the low display after assembly.
Point-by-point correction is a technology used to enhance LED electronic screens’ luminance uniformity and fidelity of color.
The process is acquiring data of each pixel on the LED display, calibrating the coefficient matrices, and then sending feedback to the display control system. The purpose is to achieve the differential drive of pixel and reduce the difference in brightness and color. This technique can stitch different LED-tailed gear batches and display beautiful and pure pictures with natural color.
According to the different applied situation, there are two forms of point-by-point correction system:
- Single LED cabinet point-by-point correction.
The system will rectify the cabinet one by one on the production line to ensure that the completed cabinets achieve a high homogeneity degree.
- Scene screen point by point correction.
The scene of the full-color LED large screen display chooses the appropriate views during on-site calibration.
The point-by-point correction has two kinds of systems. These are Point-by-point Correction Chromaticity and Brightness Adjustment.
1.The brightness correction is LED Luminous intensity correction. At present, due to some
correction machines, it cannot accurately measure the luminous intensity. However, the devices can not accurately measure the color deviation.
2.Color correction refers to a way that uses a metering instrument with color distinguishability. This way can measure the brightness and chroma value of LED.
Why is LED Display Chromatic Abberation important?
The use of different batches of the same wavelength shift LED Displays. It is necessary for luminance and chrominance correction. It can ensure the whole LED electric display screen brightness consistency and present a typical color picture. Tail gear products are generally more prominent than the market price file.
Through point-by-point correction technology, the different batches of tail files can play a normal function. Additionally, it improves the use valve of the LED Display products and saves costs for our customers.
