TFT screen note parameters
Release Time:2022-09-27
There are three important indices that an LCD screen needs to pay attention to:  
The first is the problem of color depth. It is what we often call 65k, 26w and so on. The screen is made up of pixels. Here, color depth refers to how many colors a pixel can display. Then the 65k mentioned earlier is a point that can display 65536 colors. More colors can perform better transition colors. (Regarding transition colors, everyone knows that in fact, the face in the photo is not expressed by a color.) It is represented by a color from dark to light or from light to dark. A little darker or lighter is actually another color. Therefore, the number of colors is larger, and the color expression on the face is more delicate, and on the contrary, it will become very stiff. The difference between 65536 and 262144 is not much, mainly because the human eye's ability to distinguish colors is limited. Look closely at the color transitions on the body, for example, to see clearly.  
Second screen material. We often say that tft or stn refers to the screen material. We don't care how he works, the best screen effect on the display effect is tft>tfd>ufb>stn. There are also more technologies such as oled that are used as external screens. For example, v868, 8280, and so on. The self-emitting contrast is also high, but it is said that Samsung's newly developed models have already used oled as the main screen. The tfd display effect is still good, but the brightness is still darker than TFT, but it is relatively power-saving. UFB also pays attention to the original UFB effect is not very satisfactory, such as LG7100 Samsung T208. However, new ones such as x608's 65536, ufb has been greatly improved compared to the previous product. Stn is in the ascendant. Some low-end machines have also begun to use TFT. There are also those in TFT such as LTPs, low-temperature polysilicon and the like, that is, the power-saving display effect is prominent, and Sharp's ace technology cg-slicon. TFT continuous polysilicon technology, better display effect, and can obtain a higher number of dots per unit area. If the above content is confused, you can basically consider it like this: cg-slicon >ltps>tft>tfd>ufb>stn These are from the display effect. Another point is the difference between the moto v303 and v300's transflective tft and transmissive tft that many people care about. It is said that the former has better clarity, while the latter can also see the screen clearly in the sun, each with its own advantages. Stn is not bright enough compared to tft, and there is a color that is easy to cast, especially easy to be yellow, easy to paste.  
The last one is the easiest to ignore. It is the screen resolution, in fact, the resolution is also a more important aspect. The screen resolution of mainstream models is 160*128, and the resolution of 160*128 is normal. For example, the high-resolution moto v303/v600 uses a resolution of 220*176, and its display area is similar to that of the general 160*128, so it can get better results. The image is more delicate, and the luster on the corner of the human mouth can be expressed. Here we also want to talk about the phone screen in qvga resolution. For example, Sharp gx22, the display effect is extremely good, reaching a resolution of 320 * 240, but the display area is relatively large. There is also a screen resolution of 320*240 for the Nec N820. This is the standard equipment of mainstream Japanese machines
