Nowadays, there are all kinds of mobile phones on the market, and the types of screens are also full of colors. How do we choose? From what perspective? Here is a comprehensive introduction to the popular mobile phone screens on the market.
According to the material classification of the screen, the current mainstream screens of smart phones can be divided into two categories: one is LCD (short for Liquid Crystal Display), that is, liquid crystal display. The other is an OLED (abbreviation of Organic Light-EmitTIng Diode), that is, an organic light emitting diode. Currently, TFTs and SLCDs, which are relatively common on the market, belong to the category of LCDs. Samsung is proud of its AMOLED series of screens that are part of the OLED category. Others such as IPS, ASV, NOVA, etc. are not screen materials, and they are called screen display technology more accurately.
If divided according to the driving method of display technology, it can be divided into two categories: passive matrix (Passive Matrix) and active matrix (AcTIve Matrix). The difference between a passive matrix and an active matrix is ​​the way in which the current is driven. When the external current passes, the arrangement of the liquid crystal changes. After the current is stopped, if the liquid crystal arrangement remains unoriginated (having memory), it is called an active matrix; and once the current disappears, it returns to the original position, and must be again. The charging can be arranged as a passive matrix.
In the LCD camp, PMLCD (short for Passive Matrix LCD) is a passive matrix liquid crystal display, including MSTN (Mono STN), CSTN (Color STN) and other technologies. Since PMLCD is not commonly used in practice, it has not been done here. More introduced. We mainly introduce AMLCD (short for AcTIve Matrix LCD), which is an active matrix liquid crystal display. And TFT is one of the AMLCDs.
In the OLED camp, it can be divided into small molecule OLED (SMOLED) and polymer OLED (PLED) according to material classification; if it is divided by driving method, it can be divided into passive matrix OLED (PMOLED) and active matrix OLED (AMOLED). Among them, PMOLED as a transitional product we do not explain too much, and AMOLED, which is also developed by Samsung, is currently widely used in mobile phones.
1, the mainstream mobile phone screen material is divided into two major categories of LCD and OLED.
2. Common TFTs and SLCDs on the market belong to LCD. Samsung AMOLED screens and their derivatives are all OLEDs.
3. IPS, ASV, and NOVA are all panel technologies based on TFT screens.
