Mobile screen knowledge popularization
2022-05-13
The mobile phone screen, also known as the display screen, is used to display images and colors. The screen size is calculated according to the diagonal of the screen, usually in inches, which refers to the diagonal length of the screen. With the increasing popularity of mobile phone color screen, the material of mobile phone screen is becoming more and more important.
Mobile phone screens are mainly divided into two types: LCD screen and OLED screen
According to the material of the screen, the mainstream screens of smart phones can be divided into two categories. One is LCD (liquid crystal display for short), that is, liquid crystal displays, such as TFT and SLCD screens;; The other is OLED (short for organic light emitting diode), that is, organic light emitting diode, such as AMOLED series screen. The fundamental difference between LCD and OLED is that OLED is self luminous, while LCD needs to be illuminated by backlight to display.
LCD：
Sharp is the industry leader, but its OLED is not good. When the market turns to OLED, the enterprise reacts too slowly and is overtaken by Samsung. BOE's LCD is worse than sharp, but it's OK. Tianma screen is relatively poor. It is mainly used in medium and low-end mobile phones. 2000-4000 mobile phones rarely use Tianma screen. However, sharp's igzo panel is not an ordinary LCD screen. It is extremely power-saving and has good color. Due to its structure, it is naturally suitable for making high score screens.
OLED：
Samsung's OLED is invincible on mobile phones. In the early years, it has insisted on using OLED on its flagship. In those years, there was indeed the problem of too gorgeous and distorted color. However, after so many years, its efforts have finally paid off in this era of OLED brilliance and become the leader of the industry.
Display module:
It is mainly divided into LCD and OLED. The LCD display module is composed of polarizer, color filter, liquid crystal, TFT (glass), backlight, etc. it is the most widely used display screen of smart phones at present; OLED display module is mainly composed of polarizer, encap (glass), organic self luminous layer and TFT (glass). It has the characteristics of self luminescence, simple manufacturing process, low energy consumption, ultra light and thin and bendable. It is one of the emerging mainstream display technologies.
Screen:
The screen is also the first impression. There are many determinants of the screen, such as resolution. 2K display must be more delicate than 1080 display. Now take your own Xiaomi 11ultra for comparison.
The high brush affects the smoothness of interface sliding. For example, when you slide the hot list interface under the high brush of 120Hz, the interface slides smoothly with a stroke of force. In the case of slow play, there is no jam, while 60Hz sliding is a little. 90hz refresh is better than 60Hz, but it is worse than 120Hz.
It is obvious that 120Hz refresh is smoother than 60Hz
Pixel density, color gamut, color accuracy and color depth are also decisive factors.
