Mobile phones have become almost indispensable in our daily lives, but how much do you know about mobile phone displays? Almost all mobile phones available on the market now use LCD as the display screen. Due to differences in quality and technology, there are roughly FSTN, CSTN, TFT, and of course there are other display types, such as the more fashionable OLED display screen. Below, we will give a brief introduction to these displays, hoping that it will be helpful to everyone. FSTN screen FSTN mobile phone screens should be the mobile phone display screens we are most exposed to, because the screens of the black and white mobile phones we used in the past were all FSTN. FSTN is a passive matrix LCD device. Its advantages are low power consumption, wide viewing angle and low price. However, its fatal flaw is that it cannot display in color and its response speed is too slow. For dynamic display, such as playing games on mobile phones, the tail is seriously off. There are countless classic mobile phones in the FSTN era. Nokia8310, MOTO V70, and SAMSUNG A288 can be regarded as outstanding representatives. As people\'s requirements for life continue to improve, technology continues to advance. Black and white mobile phone screens are facing the fate of being completely eliminated, and color mobile phone screens have emerged. Major mobile phone manufacturers even call 2004 the year of color screens. CSTN screen The display principle of CSTN is to add a color filter to the traditional monochrome FSTN liquid crystal display, and divide each pixel in the monochrome display matrix into three sub-pixels, displaying the three primary colors of red, green, and blue through color filters respectively, and the three sub-pixels can display color pictures through spatial color mixing. CSTN and FSTN have the same display principle and are both passive matrix LCDs. Power saving is its biggest advantage, but it also has the disadvantage of slow response speed. At the same time, due to the problem of color compensation, CSTN itself cannot achieve a complete black and white background, so its color reproduction ability is far inferior to TFT. …
