Understand the mobile phone screen in one picture. You are right to buy a mobile phone according to this

With the advancement of technology, mobile phone screens have become the most direct interactive interface for mobile phone users, and their quality is directly related to the user experience. In the mobile phone market in 2024, factors such as brightness performance, eye protection effect, resolution, and deep color gamut color accuracy have become important considerations for consumers when choosing mobile phones.

The brightness performance of the mobile phone screen directly affects the user's visual experience in various light environments. A high-brightness screen can still be clearly seen under strong light outdoors, while a low-brightness screen can reduce eye fatigue at night or in dark light environments. Therefore, when choosing a mobile phone, consumers should pay attention to parameters such as the maximum brightness of the screen, sunlight-stimulated brightness, and automatic brightness adjustment function.

The manual maximum brightness reaches 600 to 800nit, the global excitation brightness exceeds 1000nit, and the local peak brightness exceeds 3000nit. The screen basically meets the needs of daily use. Higher values ​​represent stronger screen parameter quality.

With the increase in the time of using mobile phones, the damage of the screen to the eyes has gradually attracted attention. Therefore, the eye protection function has become an important consideration for mobile phone screens. Currently, many mobile phones on the market are equipped with eye protection technologies such as eye protection mode and high-frequency PWM dimming to reduce screen flicker and blue light damage to the eyes. In addition, some high-end mobile phones also use self-luminous screen technologies such as OLED and AMOLED to further improve eye protection.

Dimming scheme is the key in eye protection technology. The full-range low-frequency PWM dimming strobe is more harmful to the eyes, while the full-range DC display effect is poor in dark light. Therefore, low-brightness high-frequency PWM + high-brightness DC dimming solution has become the first choice for OLED mobile phones.

3. Resolution: Delicate presentation of every pixel

Resolution is one of the important indicators for measuring the display effect of a mobile phone screen. A high-resolution screen can present more detailed and clear images and text, improving the user's visual experience. When purchasing a mobile phone, consumers can pay attention to parameters such as screen resolution and pixel density, and choose a screen with high resolution. Currently, resolutions from 1.5K to 2K can meet the needs of most users, providing detailed and clear display effects.

The color depth, color gamut and color accuracy of the mobile phone screen are crucial to the user's visual experience in scenarios such as watching videos and browsing pictures. Excellent color depth, color gamut, and color accuracy can ensure that the colors displayed on the screen are more realistic and accurate, allowing users to experience a more realistic visual experience. Although manufacturers generally promote P3 color gamut and color accuracy of ΔE

① Color gamut coverage affects the color expression ability of mobile phones, and irregular color accuracy may lead to color cast problems. For users who pursue color accuracy, it is recommended to refer to the real machine evaluation results.

②In terms of color depth, mainstream products in the market currently generally use 10bit, and there is not much difference in this aspect.

To sum up, the brightness performance, eye protection effect, resolution, color depth, color gamut, color accuracy and other factors of the mobile phone screen together constitute the comprehensive performance of the mobile phone screen. When consumers choose a mobile phone, they should consider these factors based on their needs and budget, and choose a mobile phone that suits them. At the same time, mobile phone manufacturers should continue to improve the technical level of mobile phone screens to provide users with a better experience.
