CTOnews.com July 18 news, sound transmission holdings announced today, recently, sound transmission research and development image team and hong kong polytechnic university color image and meta-universe research center cooperation "display screen color calibration" project has achieved new results, through self-developed high-standard screen calibration method and landing production line, to achieve screen color consistency and accuracy.

The research paper "Color Characterization Model for OLED Displays with Crosstalk Effects" was accepted by Color Research & Application, a well-known international journal in the field of color science.

According to introduction, in the image processing of intelligent terminal equipment, because the color range of image imaging to image information content display is different, in order to accurately restore the true color of different image content on various devices, it is necessary to carry out color management for the whole link link from image imaging to display. The color calibration of the display screen is the basic link in color management, which can make the picture present relatively consistent color gamut coverage and color difference. If you cannot accurately control the color of the display screen, it will greatly affect the visual experience of the end consumer.

In order to improve the accuracy of Mobile device display and the comfort of consumer visual experience, this study proposes a new characterization model for the crosstalk problem existing in OLED screen. By measuring the tristimulus values corresponding to 64 sets of RGB signals on the screen, the screen is characterized and modeled, and the screen is accurately calibrated to sRGB or P3 standard.

According to Sound Transmission Holdings, the screen calibration scheme realizes a fully automatic rapid color calibration scheme on the Mobile device platform, which can reduce the color difference ΔE00 from 3.96 to 0.72, reaching the "industry-leading level," greatly improving the consistency and accuracy of screen color.

▲ At present, this technology has opened up the automatic color correction link of production line, which is first applied to the high-end models under the company, and will gradually be popularized to the middle and low-end models. This color calibration research project laid the foundation for the construction of P3 color gamut full-link color management. In the next step, the sound transmission will continue to promote the upgrade of screen color technology and product application, and accurately control the color of the display screen.
