OPPO Find X3 Pro: display suitable for those suffering from color blindness


OPPO, thanks to the billion-color display of the new Find X3 Pro smartphone, guarantees optimal visibility of images even for people who suffer from this vision problem.

It is commonly believed that people perceive colors in exactly the same way. However, scientific research and data show that Color Vision Deficiency (CVD), the disorder that alters the vision of certain colors and leads to color blindness, affects about 1 in 12 men and 1 in 200 women worldwide.

Find X3 Pro: a display designed for all to see

Colour Vision Enhancement

OPPO’s goal is to guarantee the best color experience to an increasing number of people, making accessible the billion shades of color that the smartphone manages to capture through images and videos, even to those with visual impairments. .

The OLED display of the smartphone has been designed to be easily calibrated to easily adapt to different individual visual abilities. To achieve this perfection in color calibration and reproduction, the company conducted research with color science experts, professors Yaguchi and luo Ming from Zhejiang University.

Research has shown that most OPPO smartphone users can be divided into three groups: people with color vision deficiency and color blindness, people with partial color vision, and people who have complete color vision.

In particular, users with partial color vision and color vision deficiency represent respectively 68% and 16% of the interviewees. Only a small percentage (16%) have full color vision.

OPPO used up to eight methods to be able to test color vision optimally, later focusing on two methods, with the help of Professor Luo Ming. These are mainly based on the false color image detection, commonly used in medicine to diagnose color blindness, and the Munsell Color System. The latter, used to analyze the different shades of color, defines colors based on three dimensional coordinates: hue, brightness and saturation. This system has allowed OPPO to maximize the accuracy of the color gradient on the screen, thus compensating for any visual deficiencies of the user.

Color vision is a matter of cone cells

The eyes have millions of light receptors called “cones” which can be divided into 3 main groups. Each of these cones reacts to a series of wavelengths, which correspond to the different colors of light. In analyzing how these photoreceptors work, OPPO focused on long, medium and short wavelengths of light (LMS). This method showed a crossover in photoreceptors, especially with regard to the medium and long wavelengths that produce green, yellow, orange and red tones.

The human brain then constructs images from the information captured by these photoreceptors, and some people may perceive specific wavelengths of color better than others. At this point, active color compensation can come into play.

The three main types of color vision deficiency

Significant impairment of long, medium or short wavelength photoreceptors is the main cause of the three forms of color blindness: Deuteranomalia (green-red), Protanomalia (red-green) and Tritanomalia (blue-yellow).

The algorithms developed for OPPO Find X3 Pro they are able to compensate for these three problems, compensating for display hues to achieve full color contrast in an image. However, this color optimization is an extremely complex process. In fact, ambient lighting can drastically affect the perception of color displayed on a screen. Typically, in environments with warm light, the colors of smartphone displays tend to appear cold and bluish. The “Nature Tone Display” function of OPPO Find X3 Pro then automatically adjusts the color temperature according to the ambient light, so that the color vision enhancement algorithm works perfectly whether you are in an environment with a soft light in both a brighter one.

Color Correction 2.0

Through the recent “Color Vision Enhancement” function, the brand has refined the color compensation algorithm. This new feature allows you to perform a color perception test from the Find X3 Pro display, adjusting the compensation and offering a personalized and tailored visual experience for each user. You can get it up to 765 display profiles, with the aim of guaranteeing an optimal and accessible experience for everyone.
