Title: Innovations of Xiaofan Feng in Chromaticity Measurement

Introduction

Xiaofan Feng is a notable inventor based in Wuhan, China. He has made significant contributions to the field of electronic measurement technologies. With a total of 2 patents, his work focuses on enhancing the accuracy and efficiency of display technologies.

Latest Patents

Xiaofan Feng's latest patents include a chromaticity measurement method and device for calibration of tiled LED display screens. This innovative method offers convenience in operation and accurate measurement. The process involves imaging emergent light from the tiled LED display screen using an objective lens. The light beam is then received with a transflective lens, which performs beam splitting to obtain two separate light beams. The first light beam is captured by an imaging sensor to create an original image, while the second light beam is processed through a movable optical fiber array coupling device to convert it into one-dimensional lattice light. This method allows for the acquisition of chromaticity and spectrum information from multiple regions of the display screen.

Another significant patent is a method for evaluating the brightness measurement accuracy of Demura equipment. This invention generates a noise-added image by introducing a random number to an original grayscale image. The measurement value corresponding to the added random number is obtained through the noise-added image displayed by the Demura equipment. The evaluation of brightness measurement accuracy is based on the correlation between the measured value and the originally added random number, providing a quantitative method to assess the performance of the Demura equipment.
