Cuando se vende la pantalla LED, es inevitable que haya colas. Debido a que estas colas son productos de diferentes lotes, el brillo es inevitablemente diferente y el efecto de visualización no es bueno después del ensamblaje. En este momento, se debe utilizar la tecnología de corrección punto-por-punto.
Eliminación de diferencias. La corrección punto-por-punto es una tecnología utilizada para mejorar la uniformidad del brillo y la fidelidad del color de las pantallas electrónicas LED. A través de la recopilación de datos de cada píxel en la pantalla LED, se proporciona una matriz de coeficiente de corrección y luego se retroalimenta a la pantalla. El sistema de control realiza el accionamiento diferencial de píxeles y reduce la diferencia de brillo y color.

Para realizar la unidad diferencial de píxeles, reduzca la diferencia de brillo y color. Esta tecnología permite unir diferentes lotes de archivos de cola, y la pantalla se puede mostrar pura y delicada, con colores reales y naturales.
1. According to the application, the point-by-point correction system is divided into two types:
1. A single LED cabinet is calibrated point by point, and the calibration is carried out on the production line to ensure that each cabinet delivered from the factory reaches a high degree of uniformity;
2, point-by-point calibration of the large screen on site, select a suitable viewing location for on-site calibration on the LED full-color large screen display site, to ensure that the display screen achieves a high degree of uniformity in the field observation location;
2. Point-by-point correction is divided into chromaticity correction and brightness correction.
1. Brightness correction is the correction of LED luminous intensity. At present, due to the lack of good color resolving power of some calibration instruments, the difference in this spectrum cannot be accurately measured, so it can only measure the luminous intensity but not accurately measure the chromaticity deviation.
2. Chromaticity correction refers to the correction method of light metering instruments with strong color resolving ability, which can more accurately measure the brightness and chromaticity value of LED.
Therefore, it is necessary to calibrate the brightness and chromaticity if different batches of tail-gear LED screens with the same main wavelength are used. It can not only ensure that the brightness of the entire LED electronic display screen is consistent, but also display the color display effect of the screen normally. The price of tail gear products is generally higher than that of large-scale products in the market. Through point-by-point correction technology, these different batches of tail gears can perform normal functions, which improves the use value of LED display products and saves customers. Large cost expenses.
